An electromagnetic clutch 11 is connected between the clutch 11 and the transmission 10. A motor shaft (not shown) of the electric motor M is interposed in series between the clutch 11 and the transmission 10.

  If the electric motor M is de-energized with the electromagnetic clutch 11 connected and the motor shaft is idled by the vehicle-side control device UV, the output of the engine E is output from the electromagnetic clutch 11, the motor shaft and the transmission 10. Thus, the wheel W can be driven by the engine E because it is transmitted to the wheel W side. On the other hand, if the electric motor M is energized from the battery B while the electromagnetic clutch 11 is disconnected, the output of the electric motor M is transmitted to the wheel W side through the transmission 10, so that the wheel W travels with the electric motor M. Can be driven. As described above, the refuse collection vehicle V is a hybrid work vehicle capable of driving and driving the wheels W using either the engine E or the electric motor M as a power source.

Is done. Of the sensors provided in the engine E, in particular, a sensor that detects that the engine is in operation and outputs an engine operating signal is also connected to the bodywork side controller UK (second controller UK2). The

  Thus, each of the vehicle-side control device UV, the engine E, the electric motor M, and the battery B is actually connected by a plurality of power lines and / or signal lines, but the display is shown in FIG. Simplified.

  The transmission 10 is provided with a power take-out device PTO capable of taking out the output of the transmission at any time, and the output side of the power take-out device PTO is a part of the bodywork K, which will be described later. Linked to and linked to P. The power take-out device PTO is connected to the vehicle-side control device UV, and the output of the transmission 10 is changed to a wheel according to an operation input to the power take-off switch P-SW that is also connected to the vehicle-side control device UV. Transmission can be selectively switched between the W side and the hydraulic pump P side. That is, when the power take-off switch P-SW is off, the output of the transmission 10 is transmitted to the wheel W side and used for driving, but when the switch P-SW is turned on, the transmission The output of 10 is transmitted to the hydraulic pump P side and used for driving the pump. In addition, since the structure function of such a power take-out device PTO is conventionally known, further explanation is omitted.

  Thus, the electromagnetic clutch 11, the power take-out device PTO, and the power take-off switch P-SW constitute the power selective take-out mechanism PS in cooperation with each other.

  In the illustrated wheel drive system D, the engine E and the electric motor M are arranged in series with each other. However, in the present invention, the electric motor M and the engine E are respectively connected in parallel with each other via an electromagnetic clutch.

  In addition, the dust container 1 is provided with a dust discharge device 7 as a working machine for discharging dust stored in the box to the outside. The dust discharge device 7 includes a discharge plate 6 that extends to the full width in the dust storage box 1 and can be moved back and forth with respect to the dust input box 3 at the loading position, a back surface of the discharge plate 6, and a dust storage box. The first cylinder A1 is interposed between the first cylinder A1 and the fourth cylinder A4, which is interposed between the front part of the first cylinder A1 and drives the discharge plate 6 forward and backward with respect to the dust box 3. Then, when the dust input box 3 is in the discharge position (raised position), the discharge plate 6 is retracted in the dust storage box 1 to force the storage dust in the dust storage box 1 from the rear end opening 1a. It can be discharged.

  Referring also to FIG. 6, a front operation panel CF is provided in the cab of the base vehicle Vb, and the operation modes of the dust loading device 2 and the dust discharge device 7 are arbitrarily set in the front operation panel CF. Various work switches CF-SW1 to 3 for selecting and operating, and second power for arbitrarily switching between an engine driving state in which the hydraulic pump P is driven by the engine E and a motor driving state in which the electric motor M is driven. A source selection switch M-SW2, an automatic switching mode for automatically controlling switching between the engine driving state and the motor driving state of the hydraulic pump P (that is, switching of the power source) and an arbitrary switching mode performed manually are selectively performed. A mode change switch SWC for switching operation and various notification lamps L1 to L6 are provided.

You may comprise so that it can return. Thus, the main switches CF-SW 1 to 3, the up / down selection switch CF-SW 2, and the advance / retreat selection switch CF-SW 3 also function as work end switches for the dust discharge process.

  Referring also to FIG. 7, the rear operation panel CR is fixed and supported on the outer surface of the dust input box 3 around the dust input port 3a. The rear operation panel CR includes various work switches CR-SW1 to 5 for arbitrarily selecting and operating the operation mode of the dust loading device 2, an engine driving state in which the hydraulic pump P is driven by the engine E, and the electric motor M. The first power source selection switch M-SW1 for switching operation between the motor driving state driven by the motor and the switching between the engine driving state and the motor driving state of the hydraulic pump P (that is, switching of the power source) is automatically controlled. A mode change switch SWC for selectively switching between an automatic switching mode and an arbitrary switching mode that is manually performed, and various notification lamps L1 to L6 are provided. The power source selection switch M-SW1 outputs a motor selection signal only when it is turned on to select a motor drive state. In the illustrated example, the rear operation panel CR is disposed on the left side of the dust input port 3a of the dust input box 3, but in addition (or alternatively), the rear operation panel CR is provided on the right side of the dust input port 3. It may be arranged.

  The various operation switches of the rear operation panel CR include, for example, a loading switch CR-SW1 that outputs a command signal for starting the loading operation to the refuse loading device 2, and the loading cycle of the dust loading device 2. A single switch CR-SW2 that selects whether to operate only once or continuously, and an emergency stop switch that outputs a command signal for emergency stop of loading operation of the dust loading device 2 and discharging operation of the dust discharging device 7 CR-SW 5 and work switches CR-SW 3 and 4 for auxiliary work are included.

  Thus, when the single unit switch CR-SW2 is switched to the single operation position while the continuous unit switch CR-SW2 is held in the continuous operation position and the loading cycle is continuously operated, the dust loading device 2 Since the loading operation ends at the same time as the end of the loading cycle being executed, the unit switch CR-SW2 also serves as a work end switch during continuous operation.

  As the auxiliary work switch, in the illustrated example, the container reversing switch CR-SW3 for reversing the mini container Ct around the dust inlet 3a and the opening / closing door 3t of the dust inlet 3a are opened and closed. Open / close switch CR-SW4 is provided. Among them, the reversing drive device 50 for the mini container Ct is conventionally known as disclosed in, for example, Japanese Patent No. 3095673, and is disposed around the dust inlet 3a. The dust in the mini-container Ct can be automatically put into the dust box 3 from the dust slot 3a by being reversely driven by the driving force of the fifth cylinder A5.

  FIG. 8 shows a schematic view of an example of the reversing drive device 50 installed at the rear end of the dust box 3, and the mini container Ct detachably connected to the device 50 is the fifth cylinder A 5. It is lifted upward by an extension operation and rotated so as to be reversed, so that the dust in the container Ct can be automatically thrown into the dust box 3. In addition, such a container reverse drive device 50 is installed in the garbage throwing box 3 as needed, and can be omitted depending on the purpose and usage of the garbage truck.

  The open / close door 3t of the dust input port 3a is attached to the dust input box 3 so as to be slidable between an open position and a closed position. Between the open / close door 3t and the dust input box 3, an open / close cylinder is provided. A door opening / closing device (not shown) that operates by the driving force of the sixth cylinder A6 is interposed.

  Further, the various notification lamp groups on the front and rear operation panels CF and CR are in a state in which the hydraulic pump P can be normally driven by the electric motor M while a vehicle key switch (not shown) is turned on. A first notification lamp L1 as a first notification means for notifying that it is, a second notification lamp L2 as a second notification means for notifying that the remaining amount of the battery B has dropped below a predetermined value, and hydraulic pressure A third notification lamp L3 as third notification means for notifying that the pump P is being driven by the electric motor M (that is, the motor is being driven), and the remaining amount of the battery B sufficiently exceeds a predetermined value. The fourth notification lamp L4 as a fourth notification means for notifying that there is a fifth notification means as a fifth notification means for notifying that the power source selection switch M-SW1, 2 is in the operation position for selecting the motor drive state. 5 Notification lamp L5 And a sixth notification lamp L6 for warning that prompts the switching operation of the power source selection switches M-SW1 and M2, and the notification contents of the notification lamps L1 to L6 are included in the front and rear operation panels CF and CR. Is attached to each.

  Thus, the sixth notification lamp L6 constitutes a warning means of the present invention, which effectively warns the operator and strongly urges the switching operation of the power source selection switches M-SW1 and M2. Blinks when lit.

  The “state in which the electric motor M can be normally driven” notified by the first notification lamp L1 means that the remaining amount of the battery B (that is, the amount of electricity charged) is sufficient, that is, not less than a predetermined lower limit value. The electric system including the electric motor M and the battery B (hereinafter simply referred to as “electric system” in this specification) for ensuring the electric motor M to operate with the electric power from the battery B is not broken. A state (that is, a state in which the electric system functions normally without a failure such as disconnection, short circuit, or element breakage).

  Thus, after switching the main switch CF-SW1 of the front operation panel CF to the loading selection position and turning on the loading switch CR-SW1 of the rear operation panel CR, the loading of the dust loading device 2 is performed. Can be started, and if the main switch CF-SW1 is switched to the discharge selection position and the up / down selection switch CF-SW2 is operated to the raised position, the dust box 3 is rotated upward, and then If the advance / retreat selection switch CF-SW3 is operated to the discharge position, the discharge plate 6 can be moved backward to discharge the stored dust in the dust storage box 1.

  The notification lamps L1 to L6 described above are appropriately color-coded for each notification function in order to make it easier to visually identify the notification function, or change the flashing mode of at least some of the notification lamps (for example, the flashing interval). May be changed). Further, as the first to sixth notification means, instead of (or in addition to) the first to sixth notification lamps L1 to L6 in the illustrated example, sound generation means for generating a predetermined notification sound or announcement sound may be used. Is possible. In this specification, the notification lamps L1 to L6 are used in a broad concept including not only a light bulb and a pilot lamp but also an LED (light emitting diode) and a liquid crystal with a backlight.

  By the way, the front operation panel CF is installed in the cab, but the operation terminal MS is further arranged as a third operation panel at a location outside the cab and away from the dust box 3. Although not shown in the figure, this operation terminal MS includes switches such as various switches CF-SW1 to 3, CF-SW1 to 4, M-SW1, and the like provided on the front operation panel CF and / or the rear operation panel CR. Is attached. Further, the operation terminal MS is provided with a display MD as a display means, at least one equipment such as a keyboard, a mouse, and a touch panel as an operation input device, and at least one equipment such as a camera and a scanner as an information input device. Is done.

  And, for example, when the operation terminal MS is installed and fixed at a suitable position on the side surface of the refuse storage box 1, the operation terminal MS becomes relatively close to the loading switch CR-SW1 and the like of the rear operation panel CR, and the wiring is collected. There is an advantage which becomes easy. Further, if the operation terminal MS is installed and fixed in the front part of the refuse storage box 1, for example, in the vicinity of a control unit box UKB described later, there is an advantage that it becomes relatively close to the bodywork side control unit UK and wiring can be easily collected.

  The operation terminal MS constitutes an arbitrary setting means of the present invention, and may be substituted by at least one of a tablet PC, other personal computer, mobile phone, handy terminal, etc. Or, to be used as a wireless remote controller, an operator can attach and detachably attach and detach using a magnetic force of a magnet or the like to an arbitrary position of a vehicle (for example, the outer surface of the dust container 1) or a fixed object outside the dust container 3 Or it may be carried or carried by a worker. In that case, the operation terminal MS and the second control device UK of the bodywork side control device UK may be detachably connected by external wiring, or may be connected wirelessly.

  Further, in the garbage storage box 1, various hydraulically operated working machines mounted on the vehicle, that is, the dust loading device 2, the dust discharging device 7, the container reversing device 50, and the dust opening door opening / closing device (hereinafter simply referred to as a working machine). The hydraulic circuit C including the hydraulic pump P is mounted. As shown in FIG. 5, the hydraulic circuit C includes a hydraulic pump P whose suction side is connected to an oil tank T, and a discharge side of the hydraulic pump P as a hydraulic oil chamber of the first to sixth cylinders A1 to A6. The first to sixth valves v1 to v6 respectively interposed in the oil passages connected in parallel and the discharge side of the hydraulic pump P and the oil tank T to suppress the discharge pressure of the hydraulic pump P to a predetermined value or less. And a relief valve R.

  The first to sixth valves v1 to v6 are operated between the hydraulic oil chambers of the cylinders A1 to A6 and the hydraulic pump P so as to switch and control the operations of the corresponding cylinders A1 to A6 independently. It is configured to perform oil supply / discharge control. When each of the valves v1 to v6 is switched to the neutral position, at the same time, the valves v1 to v6 and the corresponding hydraulic oil chambers of the cylinders A1 to A6 are shut off, and the cylinders A1 to A6 are hydraulically locked. As a result, the corresponding work machine is stopped and locked at the current work position. In the illustrated example, the first to sixth valves v1 to v6 are centrally arranged as a multi-valve MV in a single base and unitized, and the multi-valve MV constitutes a valve device.

  The hydraulic pump P is composed of a variable displacement displacement type hydraulic pump, and in this embodiment, in particular, a plurality of plungers that are annularly arranged in a pump casing (not shown) and are slidably fitted, and end portions of the plungers It is composed of a swash plate plunger pump that has a swash plate that is in sliding contact with the pump casing and that can rotate relative to the pump casing. By changing the inclination angle of the swash plate, the operation stroke of each plunger, and hence the pump discharge capacity is changed. It is possible. An electric actuator A that drives the swash plate is linked to and connected to the swash plate to change the inclination angle. Since the structure of such a swash plate type plunger pump is conventionally well-known, further description is abbreviate | omitted. If such a swash plate type plunger pump is used as the hydraulic pump P, there is an advantage that the discharge capacity can be easily changed and the switching control can be performed quickly and accurately. The actuator A can be appropriately selected from an electromagnetic actuator, an electric motor or the like, and an electromagnetic actuator is used in this embodiment.

  By the way, the bodywork K is provided with a bodywork-side control device UK that is independent from the vehicle-side control device UV, and this is a control unit attached to an appropriate place (the front end portion in the illustrated example) of the dust container box 1. Built in box UKB. This body control unit UK is a multi-valve for controlling the operation of the work machine according to operation inputs to the various work switches CF-SW1 to 3 and CR-SW1 to 5 of the front and rear operation panels CF and CR. A first control unit UK1 having a microcomputer as a main part and capable of outputting a valve control signal to the MV, and intervening between the first control unit UK1 and the vehicle-side control unit UV to exchange signals, that is, an interface function It is comprised from the 2nd control apparatus UK2 which can exhibit. The vehicle-side control device UV and the bodywork control device UK are both activated by turning on the vehicle-mounted power supply when the vehicle key switch is turned on, and the key switch is turned off. In response to this, it becomes de-energized and stops operating.

  The first control unit UK1 is basically a control device having the same structure as the control device for work equipment that is conventionally mounted and used in the dust collecting vehicle V so as to control the operation of the dust loading device 2 and the dust discharge device 7. To this, various work switches CF-SW1 to 3 and CR-SW1 to 5 provided on the front and rear operation panels CF and CR are connected so as to receive the operation input signals. The first control unit UK1 is connected to a multi-valve MV (each valve v1 to v6) that controls the operation of various cylinders A1 to A6 that operate the work implement, and individually outputs an operation command signal to the valves v1 to v6. Is possible.

  Further, the first control unit UK1 can output an idle up signal for idling up the engine E to the second control unit UK2 when it is determined from the operation input status of the various work switches that the work implement is operating. In response to the input of this idle up signal, the second control unit UK2 can output a work implement operating signal indicating that the work implement is operating to the motor control unit of the vehicle side control unit UV. An electronic governor signal is output to the engine control unit of the side control device UV so that the engine speed can be increased (idle up).

  On the other hand, the first and second power source selection switches M-SW1, 2 are connected to the second control unit UK2 so as to receive the operation input signals, and the first to sixth notification lamps L1-6 are provided. It is connected so that the notification (lighting) operation can be performed by the output current from the second control unit UK2.

  In addition, the second control unit UK2 sends a motor drive command signal to the motor control unit of the vehicle-side control unit UV in response to the power source selection switches M-SW1 and M2 being turned on to output a motor selection signal. Based on the motor drive command signal and the work implement operating signal, energization from the battery B to the electric motor M (accordingly, motor operation) can be executed.

  That is, when the vehicle-side control device UV receives a motor drive command signal from the second control device UK2, the vehicle-side control device UV controls the engine E, the electric motor M, and the power selection / removal mechanism PS so that the power source of the hydraulic pump P is the electric motor M. When the motor drive command signal is not received from the second control unit UK2 (that is, when the engine start command signal is received), the engine E, the electric motor M, and the power are used so that the power source of the hydraulic pump P is the engine E. The selective extraction mechanism PS can be controlled.

  Thus, the second control unit UK2 controls the hydraulic pump P with the engine E in response to an operation input to the first and second power source selection switches M-SW1, 2 and in cooperation with the vehicle-side control unit UV. The engine drive state to be driven and the motor drive state to be driven by the electric motor M can be switched. The electromagnetic clutch 11 directly involved in switching the power source and the second control unit UK2 and the vehicle side control unit UV for controlling the operation of the electric motor M and the engine E in connection with the clutch switching. The power source switching device X of the present invention is configured in cooperation with each other.

  And the 2nd control apparatus UK is memory | storage part C1 which memorize | stores the motive power source selection information preset corresponding to each of several surrounding environment condition of the working vehicle detected by several detection means SE1-4, A power source selection unit C2 for selecting a power source based on the power source selection information stored in the storage unit C1 and a plurality of surrounding environmental conditions of the work vehicle detected by the detection means SE1 to SE4, and the power source selection unit And a switching control unit C3 that switches and controls the power source switching device X to operate the work implement with the power source selected in C2.

  Thus, the storage unit C1 stores, for example, a plurality of surrounding environmental conditions of the work vehicle in each table of FIGS. 11 and 12, for example, work time (time) of the work vehicle detected by the clock SE1 as a time sensor, and GPS The working position of the work vehicle detected by the position sensor SE2 such as a sensor, the noise of the surrounding environment of the working vehicle detected by the noise sensor SE3, and the brightness of the surrounding environment of the working vehicle detected by the illuminance sensor SE4, respectively. The associated power source selection pattern is stored as a plurality of power source selection information.

  In this case, for example, the power source selection information corresponding to the work time (time) of the work vehicle detected by the time sensor SE1 is selected according to the work time (that is, nighttime or daytime) in the setting example of FIG. The setting can be changed arbitrarily by the operator by clicking on a predetermined part of the display scene as appropriate while viewing the display MD of the operation terminal MS as an arbitrary setting means. It is convenient. In addition, since reference information (for example, sunrise, sunset time, etc.) is displayed on the display MD when the setting is changed, the setting can be performed easily and accurately using this as a guide.

  Further, for example, the power source selection information corresponding to the work position of the work vehicle detected by the position sensor SE2 is an electric or engine according to position information such as latitude and longitude of a specific dust collection place in the setting example of FIG. Driving or selection (electrical priority or engine priority) is set in advance, and a power source is selected based on the setting contents and position information detected by the GPS sensor SE2. Concerning the setting relating to the position information, it is convenient that the operator can arbitrarily change the setting by appropriately clicking a predetermined part of the display scene while viewing the display MD of the operation terminal MS as an arbitrary setting means. In addition, as another setting method, the position data of the dust collection place is converted into a barcode in advance, and the list of the dust collection places with barcodes carried by the operator is read by the scanner of the operation terminal MS. The position information may be specified. As another setting method, image data of the characteristic landscape of the dust collection location is stored in advance, and the dust collection location is specified from this and the image data taken with the camera as the information input device of the operation terminal MS You may make it do.

  Further, for example, the power source selection information corresponding to the noise in the surrounding environment of the work vehicle detected by the noise sensor SE3 does not cause the engine noise at the upper sound pressure level (for example, 65 dB) or more in the setting example of FIG. Electricity is set when the engine is driven and the lower sound pressure level (for example, 50 dB) or less, and selection (electricity priority) is set at the intermediate sound pressure level. These settings are also convenient because the operator can arbitrarily change the settings by appropriately clicking a predetermined part of the display scene while viewing the display MD of the operation terminal MS as an arbitrary setting means. In addition, when changing the setting, reference information (for example, environmental standards for noise and specific sound pressure levels at typical noise locations) is displayed on the display MD. Can be done.

  In addition, for example, the power source selection information corresponding to the brightness of the surrounding environment of the work vehicle detected by the illuminance sensor SE4 indicates that in the setting example of FIG. In the lightness level zone where the electric power is lower than the lower lightness level (for example, 200 lux) or lower than the upper lightness level and brighter than the predetermined intermediate lightness level (for example, 900 lux), the selection (engine priority) is selected. Selection (electric priority) is set for each lightness level band that is darker and brighter than the lower lightness level. The setting is also convenient because the operator can arbitrarily change the setting by appropriately clicking a predetermined part of the display scene while viewing the display MD of the operation terminal MS as an arbitrary setting means. In addition, when changing the settings, reference information (for example, typical time zones of the day or specific brightness at typical locations in the room) is displayed on the display MD. It can be done easily and accurately.

  Further, the plurality of power source selection information stored in the storage unit C1 is in the surrounding environment state of the work vehicle ignoring the operation position of the power source selection switches M-SW1 and M2, as exemplified by the dotted frame in FIG. First power source selection information that causes the power source selection unit C2 to select a corresponding specific power source, and second power source selection information that prompts the user to select a specific power source corresponding to the surrounding environment of the work vehicle. And is classified.

  Furthermore, in the storage unit C1, the plurality of powers set in advance corresponding to a plurality of surrounding environmental conditions (time, position, noise, brightness) of the work vehicle respectively input from the plurality of detection units SE1 to SE4. In addition to the source selection information, as exemplified by the dotted frame in FIG. 10, the power source priority order set in advance for a plurality of surrounding environmental conditions, and the sensor priority order set in advance for a plurality of detection means SE1 to SE4 Is remembered. The selection of which priority is to be valid (step S204 described later) is provided at an appropriate position of the operating terminal MS or the bodywork K (for example, the operation panel CR or CF). Using a selection switch or the like that can be connected to the second control unit UK2 of the device UK, it is set to any one at the factory shipment stage of the product, and can be changed and set at any time after the shipment according to the user's desire or the like.

  Then, when the former priority order is selected and set, the second control device UK2 of the bodywork side control device UK uses the power source selection unit C2 to select the power source based on a plurality of surrounding environment conditions of the work vehicle. When selecting, if multiple power source selection information corresponding to the multiple types of surrounding environmental conditions are conflicting (that is, different) information, one of the surrounding environmental conditions prioritized by the power source priority order Since the power source is selected based on the power source selection information corresponding to the power source selection information, the power source selection information to be used for the selection can be appropriately narrowed down and the power source can be selected accurately.

  On the other hand, when the latter priority is selected and set, when the power source selection unit C2 selects a power source based on a plurality of surrounding environment conditions of the work vehicle, the plurality of types of surrounding environment conditions are dealt with. When the plurality of power source selection information are conflicting (that is, different) information, the power source is selected based on the power source selection information corresponding to the detection output of any of the detection means SE1 to SE4 prioritized according to the sensor priority. In this case, too, the power source selection information to be used for the selection can be appropriately narrowed down to appropriately select the power source.

  Note that a check column for setting validity / invalidity of detection outputs of the detection means SE1 to SE4 is displayed on the display means MD of the operation terminal MS. Then, by selecting the presence / absence of a check mark in the check column with the operation input device of the operation terminal MS, the validity / invalidity of the detection output of each of the detection means SE1 to SE4 can be arbitrarily set. Only the power source selection information corresponding to the detection output of the detection means validated by the setting is used as basic information for power source selection.

  Thus, when the second power source selection information is input to the power source selection unit C2, the second control device UK2 of the bodywork side control device UK has a specific power corresponding to the surrounding environment of the work vehicle. When the power source is selected by the power source selection switches M-SW1 and M2, the sixth notification lamp L6 as a warning means is blinked for a predetermined time when the power source is not selected. The power source selection unit C2 selects a power source based on the operation position of the source selection switch M-SW1, 2, and a specific processing example will be described later.

  Furthermore, the second control unit UK2 can input the output signal of the main switch CF-SW1 of the front operation panel CF to this, and it is in the loading operation selection state or the discharge operation selection state from the output signal. Can be determined. Based on the determination result, the second control unit UK2 makes the switching operation signal from the power source selection switch M-SW1 valid while the loading operation is selected, but the switching operation signal from the power source selection switch M-SW2 is On the other hand, while the discharge operation is selected, the switching operation signal from the power source selection switch M-SW2 is validated, but the switching operation signal from the power source selection switch M-SW1 is invalidated. Instead of such a control mode, the first and second power source selection switches M-SW1, 2 may be configured to be switched independently of each other.

  Further, a motor drive permission signal can be output from the vehicle side control device UV to the second control device UK2 side. However, the motor drive permission signal indicates that the electric system is normal and the battery B is out of battery (that is, the remaining amount is less than a predetermined lower limit), and the electric system is normal but the battery B The output mode (for example, duty ratio of the output signal) is set to be different from the case where the remaining amount of battery is reduced to a certain extent (that is, below a predetermined value higher than the predetermined lower limit value), and the electric system fails Alternatively, when the battery B has run out, the motor drive permission signal is not output. The motor drive permission signal may be output only while the vehicle-side control device UV is receiving the work implement operating signal.

  Although not shown, a failure diagnosis circuit for detecting the presence or absence of a failure in the electric system is provided between the battery B and the electric motor M. The failure diagnosis circuit and the battery sensor provided in the battery B are provided. Are input to the vehicle-side control device UV, so that the vehicle-side control device UV determines which output mode of the motor drive permission signal should be output or whether the output should be stopped. The

  Further, an engine operating signal for identifying whether the engine E is operating or stopped can be input from a sensor provided in the engine E to the second control unit UK2 of the body control unit UK. A battery remaining amount signal indicating the remaining amount of the battery B can be input from a sensor provided in the battery B, and is output when the engine E is started by an operation input to the starter switch S-SW. An engine start signal can be input from a sensor provided in the starter switch S-SW.

  Then, the second control unit UK2 has front and rear operation panels based on the motor drive permission signal from the vehicle side control unit UV and the motor selection signal from the power source selection switches M-SW1 and M2 input thereto. The first and fifth notification lamps L1 to L5 of CF and CR can be controlled (lighted), and the battery B is out of battery when the hydraulic pump P is driven (that is, the remaining amount falls below a predetermined lower limit value). Or an emergency stop signal is output to the first control unit UK1 when it is determined that an abnormality has occurred in the electrical system. In this case, when the first control unit UK1 receives the emergency stop signal from the second control unit UK2, the multi-valve MV (each valve v1) controls the operation of the multi-valve MV to the neutral position so that the work implement is emergency-stopped. ~ V6) to output a stop command signal.

  The work implement emergency stop method based on the operation control of the multi-valve MV by the first control device UK1 described above is performed by the first control device UK1 when the emergency stop switch CR-SW5 is turned on during operation of the work implement. This is the same as the method of urgently stopping the work machines simultaneously by controlling the operation of the valve MV to the neutral position. In particular, in the present embodiment, the wiring for outputting the emergency stop signal from the second control unit UK2 is connected to the wiring of the emergency stop switch CR-SW5. Therefore, for the emergency stop signal input from the second control unit UK2 The emergency stop signal can be sent from the second control unit UK2 to the first control unit UK1 without specially providing the input terminal of the first control unit UK1. Note that the wiring for outputting the emergency stop signal from the second control unit UK2 can be directly connected to the first control unit UK1 without being connected to the wiring of the emergency stop switch CR-SW5.

  Thus, in the bodywork side control device UK of the present embodiment, the motor drive state and the engine drive state of the hydraulic pump P according to the operation input to the first and second power source selection switches M-SW1,2. When the switching control is performed, the signal input / output unit on the body side control device UK side of all signals to be exchanged between the body side control device UK and the vehicle side control device UV is the second control device. Only provided in UK2.

  Accordingly, in the bodywork side control unit UK, the interface function parts that should exchange information (signals) between this and the vehicle side control unit UV can be aggregated in the second control unit UK2, so Various work switch groups CF-SW1 to 3 on the operation panels CR and CF; a conventionally known work machine control device (that corresponds to the first control device UK1) that controls the work machine based on operation inputs to the CR-SW1 to 5 The newly developed second control unit UK2 is simply added to and connected to the newly developed second control unit UK corresponding to the hybrid work vehicle. It becomes possible. As a result, the development cost can be reduced and the development period can be shortened. Also, a component (that is, a first work) is required between a normal type work vehicle that drives a hydraulic pump for a work machine only by an engine and a hybrid type work vehicle. The control device corresponding to one control device UK1 is shared.

  Further, as described above, the second control unit UK2 of the present embodiment is operated when the battery B runs out of the battery B or the electric system fails in the motor drive state of the hydraulic pump P, or the engine E is started. In this case, the first control unit UK1 converts the signal output from the vehicle-side control unit UV into a conventionally known emergency stop signal so that the multi-valve MV is controlled to stop the work implement in an emergency. 1 Outputs to the control unit UK1. Therefore, in the bodywork side control unit UK, the conventionally known first control unit UK1 for controlling the work implement is used as it is, but an emergency stop signal is output from the second control unit UK2 having the interface function thereto. As a result, the work machine can be stopped urgently, and the overall control configuration can be simplified as much as possible.

  The second control unit UK2 is connected to the electromagnetic actuator A for driving the swash plate of the hydraulic pump P, and can output a swash plate angle change signal to the actuator A. Then, based on the swash plate angle change signal, the electromagnetic actuator A changes the swash plate angle to drive the stroke of each plunger of the hydraulic pump P, and thus the discharge capacity, whether the hydraulic pump P is in the engine drive state or the motor drive. Change control can be performed depending on whether the state is present.

  For example, in the illustrated example, the second control unit UK2 outputs a swash plate angle change signal to the swash plate driving actuator A only in the motor driving state, whereby the discharge capacity of the hydraulic pump P in the motor driving state is output. (For example, 80 cc / rev) is set to be larger than the discharge capacity (for example, 63 cc / rev) in the engine driving state. As a result, even when the electric motor M is rotated at a low speed for noise countermeasures or the like in the motor driving state, it is possible to secure a discharge oil amount necessary for driving the work machine by setting the hydraulic pump P to a relatively high discharge capacity. It becomes. Further, in the engine driving state, even if the engine E is rotated to a certain degree of high speed to prevent engine stall etc., it is effective to set the hydraulic pump P to a relatively low discharge capacity, so that the amount of discharged oil becomes excessive. It becomes possible to prevent. Instead of the discharge capacity control as described above, the discharge capacity of the hydraulic pump P may be set to be kept constant regardless of the switching of the power source.

Next, the operation of the embodiment will be described.
[Loading process]
The loading process of the charged dust in the dust charging box 3 by the dust loading device 2 includes the dust charging box 3 at the loading position (solid line in FIG. 1) and the discharge plate 6 near the rear end of the dust storage box 1. The process is started in a state where each is held at a predetermined retracted position. In this case, after the main switch CF-SW1 of the front operation panel CF is operated to the loading position, the loading process is started by turning on the loading switch CR-SW1 of the rear operation panel CR. The loading cycle is operated only once or continuously according to the operation position of the single unit changeover switch CR-SW2. During continuous operation, if the single unit changeover switch CR-SW2 is switched to the single operation position, the dust loading device 2 stops at the end of the loading cycle.

The dust pushed into the dust storage box 1 by the execution of the loading process is stored in the dust storage box 1 while being appropriately compressed between the discharge plate 6 and the dust loading device 2. In this case, in the illustrated example, the discharge cylinder A4 is gradually contracted by the compression reaction force that the discharge plate 6 receives from the stored dust, and the discharge plate 6 is gradually advanced.
[Discharge process]
When the garbage container 1 is filled with the contained dust, the garbage truck V is moved to the garbage disposal site. In the garbage disposal site, the main switch CF-SW1 of the front operation panel CF is operated to the discharge selection position, and if the vertical selection switch CF-SW2 is operated to the raised position, the dust input box 3 is rotated upward, Thereafter, when the advance / retreat selection switch CF-SW3 is operated to the discharge position, the discharge plate 6 can be moved backward to discharge the stored dust in the dust storage box 1. After the discharge process is completed, the up / down selection switch CF-SW2 is lowered to rotate the dust input box 3 back to the loading position, and the advance / retreat selection switch CF-SW3 is operated to advance. In a state where 6 is returned to the predetermined retracted position at the rear part of the dust storage box 1, the discharge plate 6 is made to stand still and wait. Then, the garbage collection vehicle V is made to travel to the dust collection place, and the next loading process by the dust loading device 2 is started from the standby state.

  Thus, in the loading / discharging process, the first control unit UK1 of the body-side control unit UK mainly operates the work switch groups CF-SW1 to 3, CR-SW1 to the front and rear operation panels CF and CR. This can be executed by outputting a valve control signal to the multi-valve MV in response to an operation input to 3 and controlling the operation of each cylinder A1 to A4 of the work machine (especially the dust loading device 2 and the dust discharge device 7). The control procedure is well known in the art and will not be described.

Next, FIG. 9 and FIG. 9 show examples of control procedures when the body control unit UK and the vehicle control unit UV cooperate with each other to switch the power source of the hydraulic pump P between the engine E and the electric motor M. This will be described with reference to FIG. These controls are performed in a state where the vehicle key switch UV and the body control device UK (first and second control devices UK1, 2) are energized with the vehicle key switch turned on. Executed.
[Basic flow of power source switching control]
First, in FIG. 9, it is determined whether or not the power take-off switch P-SW has been turned on (step S1). If the power take-off switch P-SW has been turned on, the process proceeds to step S2, and the operation position of the mode switch SWC is automatically switched. It is determined whether the mode or the arbitrary switching mode (that is, the manual mode).

  If it is determined in step S3 that the mode is the arbitrary switching mode, the process proceeds to step S3, where it is determined whether any of the power source selection switches M-SW1, 2 is turned on (ie, motor drive selection). That is, in the case of engine drive selection), the routine proceeds to step S4, where it is determined whether or not the engine is operating. If NO is determined in step S4, the process proceeds to step S5, where an engine start command signal is output from the second control unit UK2 to the vehicle side control unit UV, whereby the engine E is started and the hydraulic pump While P is driven, the electromagnetic clutch 11 is in a connected state, and then the process proceeds to step S6.

  On the other hand, if it is not NO in step S4 (that is, the engine is operating), step S5 is skipped and the process proceeds to step S6. At this time, the hydraulic pump P is driven by the engine E. However, since the valves v1 to v6 of the multi-valve MV are in the neutral position, the oil discharged from the hydraulic pump P passes through the relief valve R and is on the oil tank T side. The cylinders A1 to A6 of the work machine are put in a standby state without being operated.

  In step S6, the work switches CF-SW1 to 3 and CR-SW1 to 4 of the work machine are operated and input to perform an arbitrary work (for example, loading process or discharging process) (for example, the main switch CF-SW1 is switched). It is determined whether or not the loading switch CR-SW1 has been turned on). If it is determined that there has been an operation input, the process proceeds to step S7, and the multi-valve MV is controlled according to the operation input. The valves v1 to v6 are switched and controlled to operate the cylinders A1 to A6 of the work machine to execute work of the work machine (for example, loading work), and then the process proceeds to step S8. On the other hand, if it is determined NO in step S6, a return is returned.

  In the step S8, when the condition for ending the work being executed is satisfied, for example, an operation input to the work switch for ending the work (for example, switching operation of the main switch CF-SW1 to the off position, loading) It is determined whether or not there is a continuous operation of the single switch CR-SW2 during the continuous operation of the process, or when the single operation of the loading process is completed. If it is determined, the process returns and the work being executed continues. On the other hand, if it is determined in step S8 that the answer is no, the process proceeds to step S9 to terminate the work being executed, and then returns.

  If it is determined in step S2 that the operation position of the mode switch SWC is in the automatic switching mode, the process proceeds to step S11, and the work environment information (work timing / position / noise / brightness) of the work vehicle. The automatic power source selection process according to The automatic selection process in step S11 will be specifically described in the subroutine shown in FIG.

  When the automatic power source selection process ends in step S11, the process proceeds to step S12, and it is determined whether the power source selected in step S11 is the engine E or the electric motor M. If it is determined in step S12 that the engine E is selected as the power source, the process proceeds to step S4. If it is determined that the electric motor M is selected, the process proceeds to step S13.

  In step S13, it is determined whether or not the battery B is out of battery (that is, the remaining amount is lower than a predetermined lower limit value) and the electric system is normal and the motor can be driven. If it is determined there to be no (that is, the motor cannot be driven), the process proceeds to step S4.

  If it is determined in step S13 that the answer is no (that is, the motor can be driven), the process proceeds to step S14, where a motor drive command signal is output from the second control unit UK2 to the vehicle control unit UV. The motor M is started to drive the hydraulic pump P, and the electromagnetic clutch 11 is disconnected. Further, the process proceeds to step S15, and in the same manner as in step S6, the work switches CF-SW1 to 3 and CR-SW1 to 4 of the work machine perform an operation input to execute an arbitrary work (for example, a loading process or a discharging process). Is determined (for example, the main switch CF-SW1 is loaded and the loading switch CR-SW1 is turned on). If not, the process returns.

If it is determined in step S15 that the result is not negative (that is, the operation input of the work switch has been received), the process proceeds to step S16 to operate the cylinders A1 to A6 of the work machine corresponding to the operation input of the work switch Thus, the work of the work machine (for example, loading work) is executed, and the process proceeds to step S8.
[Power source selection process flow]
FIG. 10 is a subroutine specifically showing the process of step S11 (FIG. 9). In FIG. 10, first, in step S200, after confirming validity / invalidity of each of the sensors S1 to S4 as detection means, only output information from the sensors SE1 to SE4 confirmed to be valid is acquired. The confirmation is performed depending on which output from the sensors SE1 to SE4 is set to be valid in advance by the operator's operation input to the operation terminal MS (whether valid / invalid is checked).

  Next, in step S201, the sensor output information acquired in step S200 is associated with a plurality of power source selection information stored in advance in the storage unit C1 of the second control unit UK2, thereby enabling effective sensor output information. The power source selection information corresponding to is extracted and input to the power source selection unit C2 of the second control unit UK2. The power source selection information extracted at this time is a first for selecting a specific power source corresponding to the work environment information of the work vehicle ignoring the operation position of the power source selection switches M-SW1 and M2. Or the second power for prompting the user to select a specific power source corresponding to the work environment information of the work vehicle by operating the power source selection switches M-SW1 and M2. Whether the information relates to the source selection information (selection priority) is also read.

  Next, the process proceeds to step S202, where power source selection information corresponding to the sensor output information extracted in step S201 is compared with each other to determine whether or not they match. If it is determined that the answer is not negative (that is, they match), the process proceeds to step S203, and the matched power source selection information is read as formal selection information, and then the process proceeds to step S207.

  If it is determined in step S202 that the answer is NO (that is, they do not match), the process proceeds to step S204, and the priority order set and stored in advance in the storage unit C1 is either the power source priority order or the sensor priority order. It is judged whether there is. If the priority order is determined to be the sensor priority order, the process proceeds to step S205 to formally select the power source selection information corresponding to the sensor with the highest sensor priority order from among a plurality of mismatched power source selection information. After reading as information, the process proceeds to step S207.

  On the other hand, if it is determined in step S204 that the priority order is the power source priority order, the process proceeds to step S206, and the power source priority order corresponding to the power source priority order highest among the plurality of mismatched power source selection information is handled. After the power source selection information is read as formal selection information, the process proceeds to step S207.

  In the step S207, the power source selection information read as the formal selection information in any of the steps S203, 205, and 206 is the selection information (selective electric motor) that particularly encourages the electric power out of the second power source selection information. If it is determined there, the process proceeds to step S208, and the power source selection information read as the formal selection information in any of steps S203, 205, 206 is It is determined whether or not the second power source selection information is selection information (selection engine priority) that prompts engine driving.

  If NO in step S208, the process proceeds to step S209, where a power source is selected based on the first power source selection information, that is, the operation position of the power source selection switches M-SW1, 2 is related. Rather, a specific power source corresponding to the work environment information (work time, position, noise, brightness) of the work vehicle is selected.

  On the other hand, if it is determined in step S207 that it is not negative (ie, priority is given to electrification), the process proceeds to step S210, and either of the power source selection switches M-SW1 and M2 is turned on as in step S3. If it is determined whether (ie, motor drive is selected) or not (ie, if motor drive is selected), the process proceeds to step S211, where the power source is selected based on the operation position of the power source selection switches M-SW1 and M2, and the end. It becomes. Therefore, in this case, motor driving is selected.

  If NO (ie, engine drive selection) is determined in step S210, the process proceeds to step S212, where the warning means L6 is activated to alert the operator to the motors of the power source selection switches M-SW1, 2. The switch to the selection side is urged, and then the process proceeds to step S213 to count the warning time. When the warning time has passed a predetermined time (for example, 5 seconds), the process proceeds to step S211 and the power source selection switches M-SW1, 2 The power source is selected based on the operation position. Therefore, when the operator does not turn on the power source selection switches M-SW1 and M2 within a predetermined time (motor drive selection), engine drive is selected against the second power source selection information.

  If it is determined in step S208 that the answer is no (that is, the selected engine has priority), the process proceeds to step S214, and either of the power source selection switches M-SW1, 2 is turned on as in step S210. If it is determined whether (i.e., motor drive selection) has been made and not (i.e., motor drive selection), the process proceeds to step S212. In step S212, the warning means L6 is activated to urge the operator to switch the power source selection switches M-SW1 and M2 to the engine selection side. Then, the process proceeds to step S213 and the warning time is counted. When the warning time has passed the predetermined time, the process proceeds to step S211, and a power source is selected based on the operation position of the power source selection switches M-SW1 and M2. Therefore, when the operator does not turn off the power source selection switches M-SW1 and M2 within a predetermined time (engine drive selection), the motor drive is selected against the second power source selection information.

  If it is determined in step S114 that the answer is NO (that is, engine drive selection), the process proceeds to step S211 to select a power source based on the operation position of the power source selection switches M-SW1 and M2. Therefore, in this case, engine driving is selected.

  As described above, when the second power source selection information is input to the power source selection unit C2 of the second control unit UK2, the work environment information (work time, position, noise, brightness) of the work vehicle is input. When the corresponding specific power source is selected by the power source selection switches M-SW1 and M2, the power source selection switch is operated immediately after the warning means L6 is operated for a predetermined time. The power source can be selected based on the operation positions of the M-SWs 1 and 2.

That is, the power source selection information input as the formal selection information to the power source selection unit C2 is the second power source selection information, and the specific power source corresponding to the surrounding environment of the work vehicle is the power source selection switch M−. When the switch SW1 or SW2 is not selected, the operator is prompted to switch the power source selection switches M-SW1 and M2 by a warning by the warning means L6. Although it is possible to select a power source that is more suitable for the power source, even if the power source selection switch M-SW 1 or 2 is not switched in spite of such a warning, the power source is selected. The intention of the operator can be more respected by performing based on the actual operation position of the switch.

According to the power source switching control mode according to the present embodiment described above (FIGS. 9 and 10), in the hybrid work vehicle V, when the mode change switch SWC is set to the arbitrary switching mode, the hydraulic operation is performed. The hydraulic pump P that supplies hydraulic oil to the working machine of the type can be selectively driven by any power of the engine E and the electric motor M based on the switching operation of the power selector switches M-SW1 and M2. It is convenient that the power source can be properly used according to the work situation and environment. For example, it is convenient that the hydraulic pump P can be driven by the electric motor M in a place such as a residential area where noise exhaust of the engine E is a problem, and the engine E can be driven in a place where the problem is not a problem.

  In particular, the second control unit UK2 of the bodywork side control unit UK corresponds to the working environment status (working time / position / noise / brightness) of the work vehicle, specifically to the detection outputs of the detection sensors SE1 to SE4. A storage unit C1 that stores preset power source selection information; a power source selection unit C2 that selects a power source based on the power source selection information stored in the storage unit C1 and the working environment of the work vehicle; And a switching control unit C3 that switches and controls the power source switching device X to operate the work implement with the power source selected by the power source selection unit C2, and is set in advance according to the working environment of the work vehicle. On the basis of the selected power source information, the work machine can be operated by automatically and accurately selecting the power source according to the detection outputs of the detection sensors SE1 to SE4 (that is, the actual working environment status). Whole and Switch operation Te is able to enhance the working efficiency is simplified, also becomes possible to effectively avoid in advance a situation that would operate the working machine with improperly selected power source.

  By the way, in the said embodiment, four types of detection sensors (namely, time sensor SE1, position sensor SE2, noise sensor SE3) in order to detect each of the four types of work environment conditions (work time, position, noise, brightness) of the work vehicle V. The detection output of the illuminance sensor SE4) is used for power source selection. However, in the present invention, the detection output of one to three detection sensors is used to detect at least one work environment situation of the work vehicle V. May be used for power source selection, or detection outputs of five or more types of detection sensors may be used for power source selection. In addition, at least a part of the detection sensors used in the embodiments of these variations may include at least a part of the same type of detection sensors as in this embodiment, or a different type of detection sensor from this embodiment may be used. May be used.

  In the embodiment, the second control unit UK2 of the bodywork side control unit UK detects the detection outputs of the detection sensors SE1 to SE4 (that is, actual working environment status) and the power source selection information stored in the storage unit C1. A specific switch (this embodiment) that allows the operator to arbitrarily operate the power source selection process (that is, step S11 in FIG. 9 and the subroutine in FIG. 10) that causes the power source selection unit C2 to select the power source of the work machine based on Is started based on an operation input to the power take-off switch P-SW), so that the power source selection process can be executed in conjunction with the switch operation to the specific switch P-SW, thereby simplifying the operation. Is achieved. In the above embodiment, the power take-off switch P-SW, which is one of the switches for preparing to start work by the work implement, is used as the specific switch for starting the power source selection process. Similarly, the main switch CF-SW1, which is one of the switches for preparing to start work, may be used as the specific switch. Further, a dedicated switch for starting the power source selection process may be provided as a specific switch on at least one of the front and rear operation panels CR, CF, and work switches CF-SW2, 3 other than the main switch CF-SW1. , CR-SW1-4 may be used as a specific switch.

  In addition, in the embodiment, the automatic switching mode for automatically switching the power source of the work machine and the arbitrary switching mode for arbitrarily switching the power source of the work machine based on the work environment state of the work vehicle are selected at any time. Since the mode change switch SWC is provided, when the automatic switching mode is selected, the power source selection control according to the operation input mode to the work switch can be automatically performed as described above. When the arbitrary switching mode is selected, the power source can be arbitrarily selected based on the operation input to the power source selection switches M-SW1 and M2, and it is convenient to use both modes according to the work environment. .

  Further, the second control unit UK2 of the present embodiment determines that the battery B has run out of battery or an abnormality has occurred in the electrical system in the motor drive state of the hydraulic pump P shown in FIG. When the motor drive permission signal is no longer output from the vehicle-side control device UV even though the work implement operating signal is input, an emergency stop signal is output to the first control device UK1 side. In response to this, the first control unit UK1 issues a stop command signal to the multi-valve MV and controls the operation to the neutral position all at once, thereby urgently stopping the working machine in operation.

  As described above, when the battery B runs out of the battery while the hydraulic pump P is in a motor drive state or when an abnormality occurs in the electric system, the work machine is stopped urgently, so that the electric motor M cannot be driven normally. Therefore, it is possible to prevent the work machine from operating unexpectedly and surely.

  In the present embodiment, the dust discharge device 7 operates as long as the up / down selection switch CF-SW2 or the advance / retreat selection switch CF-SW3 is operated. For example, the dust discharge box 3 is moved from the loading position (lowering position). When the worker interrupts the operation of the up / down selection switch CF-SW2 while being rotated upward toward the discharge position (raised position), the dust box 3 is stopped at a position below the discharge position. In this case, although the operation of the work machine (the dust discharge device 7) is temporarily stopped, the power source switching control of the hydraulic pump P based on the switching operation input of the power source selection switches M-SW1 and M2 is performed. May be executable.

  Further, even when the emergency stop switch CR-SW5 is operated and the work machine is urgently stopped, the operation is temporarily stopped. Therefore, the power source of the hydraulic pump P based on the switching operation input of the power source selection switches M-SW1 and M2. Switching control can be executed. When safety cannot be sufficiently ensured during an emergency stop or when safety is a top priority, the power of the hydraulic pump P based on the switching operation input of the power source selection switches M-SW1 and M2 after the emergency stop is provided. It may be set to prohibit the source switching control.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to these embodiment, Various embodiment is possible within the scope of the present invention.

  For example, in the above-described embodiment, a so-called compression plate type garbage collection vehicle is illustrated as a work vehicle. However, in the present invention, a dust collection vehicle equipped with a so-called rotation plate type dust collection device by cooperation of a rotation plate and a push plate. Alternatively, a dust collection vehicle equipped with a so-called dump-type dust discharge device that tilts the dust storage box 1 may be used. In the present invention, the work vehicle is not limited to a garbage truck, and other various work vehicles that drive the work machine with a hydraulic pump, such as a concrete mixer truck, a concrete pump truck, a container transporter with a container loading / unloading function, The present invention can be applied to work vehicles such as an automobile wholesale transport vehicle with an automobile loading / unloading function.

  In the above embodiment, the engine or the electric motor is selectively switched as an indirect power source of the work machine (that is, as a power source of a hydraulic pump that drives the work machine). The engine or the electric motor may be selectively switched as a direct power source of the work machine.

  Moreover, in the said embodiment, although what was implemented in the hybrid vehicle which enabled the motive power of the electric motor M not only to drive a hydraulic pump but to drive a wheel was shown, in this invention, the motive power of the electric motor is shown. You may make it use only for the drive of a hydraulic pump. In this case, an electric motor dedicated to driving the pump, a battery that supplies electric power to the electric motor, an engine that is configured separately and independently from a traveling engine that applies driving force to the wheels, and is used only for driving a hydraulic pump, An embodiment in which a power switching device capable of selectively switching the power source of the hydraulic pump to either an engine or an electric motor is mounted on the bodywork K can also be adopted. In this embodiment, in the embodiment, The functions of the engine / motor control unit of the vehicle-side control device UV may be configured such that the body-side control device UK, particularly the second control device UK2, is responsible for the control of the engine / motor on the body UK side.

  In the embodiment, each power source selection switch M-SW1, 2 has a motor drive selection position (on operation position in the embodiment) and an engine drive selection position (off operation position in the embodiment). In the present invention, both the selection positions can be alternately selected by one switch. However, in the present invention, any power source selection switch M-SW1, 2 can be switched before the operation. The driving state (for example, engine driving state) of the hydraulic pump may be switched to another driving state (for example, motor driving state). In addition, only the power source selection switch that performed the power source selection operation of the hydraulic pump (for example, the ON operation for selecting the motor drive) last time among the plurality of power source selection switches M-SW1, 2 is the next power source. You may comprise so that switching operation (for example, OFF operation for selecting engine drive) can be performed.

  In the above embodiment, the motor drive state is selected by turning on the power source selection switches M-SW1 and M2, and the engine drive state is selected by turning off the power source selection switch M-SW1, but the power source selection switch M-SW1 is selected. , 2 may be output so that the two power sources (motors and engines) can be distinguished and selected. For example, the engine drive is selected by the on operation and the motor drive is selected by the off operation. You may comprise.

  In the above embodiment, the power source selection switches M-SW1 and M2 are dedicated to switching the power source of the hydraulic pump. However, in the present invention, the existing work switch is also used as the power source selection switch. Also good. For example, when the main switch CF-SW1 is also used as a power source selection switch, the main switch CF-SW1 is automatically returned from the loading position or the discharge position to the off position side. After selecting the position or the discharge position, the power source is switched when the same operation position is operated again, the power source is further switched when the same operation position is operated again, and the power source is further switched when the same operation position is operated again. You may enable it to perform alternate switching operation in the procedure of switching.
