  In general, in a one-box type or minivan type vehicle, a vehicle door control device called a so-called auto slide door that automatically opens and closes by sliding a rear side door by a driving force of a door opening / closing means equipped with a motor or the like. Is adopted. This kind of vehicle door control device is, for example, a door opening / closing motor having a sliding door opening / closing motor and an electromagnetic clutch that is provided so as to be able to contact and separate from the sliding door opening / closing motor and transmits a driving force of the sliding door opening / closing motor to the sliding door when connected. By means of selecting the automatic opening / closing by a main switch for selecting automatic opening / closing or manual opening / closing of the sliding door, the door opening / closing means is controlled to automatically open / close the sliding door.

Further, in such a vehicle door control device, when the free fall manual opening and closing time and the own weight of the sliding door, in order to prevent the opening and closing child by a sliding door requires more speed, the electromagnetic clutch, during manual opening and closing In addition, it has been proposed to perform control to suppress the opening / closing speed of the sliding door to a predetermined speed or less during natural fall (see Patent Document 1).

JP-A-8-270315 (see paragraphs 0004, 0014 to 0016 and FIG. 4)

  By the way, in the conventional apparatus described in Patent Document 1 described above, when the sliding door opens and closes due to its own weight drop, the inconvenience that the opening and closing speed of the sliding door becomes faster than necessary is solved, but at the time of manual opening and closing and natural falling Since the opening and closing speed is always limited by the electromagnetic clutch, there is a problem that even if the user wants to close the sliding door quickly, it cannot be closed quickly, and the user's intention is not reflected.

  The present invention is capable of opening and closing a sliding door quickly by relaxing the suppression of the opening and closing speed of the sliding door when the user indicates that he / she wants to open and close the sliding door quickly even during manual opening and closing or natural fall. The purpose is to.

In order to achieve the above object, a vehicle door control device according to the present invention transmits a driving force of a motor to a door driving mechanism to automatically open and close a sliding door, and the driving force of the motor is applied to the door driving mechanism. Door opening / closing means that allows the sliding door to be opened and closed manually without transmission, a main switch for selecting whether to automatically open or close the sliding door, and automatic opening / closing by operating the main switch upon selection, to transmit the driving force of the motor to the door drive mechanism, said upon selection of the manual opening and closing by the operation of the main switch, the electromagnetic clutch does not transmit the driving force of the motor to the door drive mechanism, manually by the user Detecting means for detecting the presence / absence of a door opening / closing operation for opening / closing the door, and an upper limit of the opening / closing speed of the sliding door by the door opening / closing means. Suppression means that suppresses the opening / closing speed to a predetermined speed or less, and when the detection of the manual door opening / closing operation by the detection means is detected, the suppression means sets the upper limit of the opening / closing speed more than when there is no detection. It is characterized in that the switching is set to be high.

According to the first aspect of the present invention, when the user wants to quickly open and close the sliding door , the door opening / closing operation is manually performed to open / close the door. By setting the upper limit of the opening / closing speed of the sliding door higher than when there is not, the control of the opening / closing speed of the sliding door can be relaxed and the opening / closing speed of the sliding door can be increased. It can be opened and closed.

It is a block diagram of one embodiment of a vehicle door control device according to the present invention. It is operation | movement explanatory drawing of FIG. It is operation | movement explanatory drawing of FIG. It is operation | movement explanatory drawing of FIG. It is operation | movement explanatory drawing of a modification.

  Next, in order to describe the present invention in more detail, an embodiment of the present invention will be described in detail with reference to the block diagram of FIG. 1 and the operation explanatory diagrams of FIGS.

  As shown in FIG. 1, the vehicle door control device of the present embodiment includes a vehicle speed sensor unit 1 that detects the vehicle speed of the host vehicle, a foot brake sensor unit 2 that detects that the foot brake is stepped on, and parking. And a parking brake sensor unit 3 for detecting that the brake is operated. Based on signals from the vehicle speed sensor unit 1, the foot brake sensor unit 2 and the parking brake sensor unit 3, a slide door ECU (described later) The Electronic Control Unit) detects whether the vehicle is not traveling, that is, in a non-traveling state, that is, in a stopped state or in a traveling state.

The vehicle speed sensor unit 1 is not limited to a configuration that directly acquires a signal from the vehicle speed sensor, but an ABS (Antilock Brake System) ECU (not shown) sends a CAN (Controller
The vehicle speed signal may be received by area network communication to detect the vehicle speed.

  Further, as shown in FIG. 1, a door latch switch 5 that detects the latch (lock) of the slide door is provided. Based on a signal from the door latch switch 5, a slide door ECU, which will be described later, closes the slide door. Whether it is present or open is detected.

  Further, as shown in FIG. 1, a main switch 6 for selecting automatic opening / closing or manual opening / closing of the slide door is provided, and when a driver or the like turns on the main switch 6, an automatic opening / closing signal is input to the slide door ECU. When the main switch 6 is turned off, a manual opening / closing signal is input to the sliding door ECU.

  In addition, a door opening / closing switch 7 for opening or closing the sliding door is provided. The door opening / closing switch 7 is provided on an outer handle and an inner handle of the sliding door and is operated from outside and inside the vehicle, An instrument panel opening / closing switch provided on the instrument panel and operated mainly by a driver, and a remote control opening / closing switch provided on a remote controller for carrying a driver in a so-called key-free system. If there is a door opening operation and a door closing operation of any one of the handle switch, the instrument panel opening / closing switch, and the remote control opening / closing switch, an opening operation signal and a closing operation signal by the operation of these switches are input to a slide door ECU to be described later. It is like that.

  Furthermore, as shown in FIG. 1, door opening / closing means 8 for automatically opening and closing the rear sliding door is provided. The door opening / closing means 8 has a door drive mechanism 83 in addition to a sliding door opening / closing motor 81 and an electromagnetic clutch 82, and the electromagnetic clutch 82 is provided on the sliding door opening / closing motor 81 so as to be freely connected to and separated from the sliding door opening / closing motor 81. At the time of connection, the driving force of the sliding door opening / closing motor 81 is transmitted to the door driving mechanism 83 via the electromagnetic clutch 82, and the sliding door is slid in the opening / closing direction by the door driving mechanism 83.

  Incidentally, the electromagnetic clutch 82 does not transmit the driving force of the sliding door opening / closing motor 81 to the sliding door when the main switch 6 is turned off and the manual opening / closing is selected. With this control, there is a function of setting a certain upper limit to the opening / closing speed of the sliding door by manual or natural fall due to the weight of the sliding door and suppressing it to a predetermined target speed (predetermined speed in the present invention) or less. As described above, the electromagnetic clutch 82 and the slide door ECU constitute the suppression means in the present invention.

  Further, the target speed described above is set in advance according to the degree of opening and closing of the slide door, and is mapped and stored in a memory not shown in FIG. Specifically, as shown in FIG. 2, a target speed is set such that the sliding door gradually decreases from a certain value as the sliding door approaches full closing (or full opening), and only one type of target speed or a plurality of target speeds are set. The types of target speeds are mapped and stored in memory. Then, the target speed corresponding to the door opening detected by the door position sensor section described later is read from the memory map, and the opening / closing speed of the slide door is set by the electromagnetic clutch 82 with the read target speed as the upper limit. It is suppressed. A fixed target speed may be set regardless of the opening degree of the slide door.

  In addition, as shown in FIG. 1, a door position sensor unit 9 that detects the door opening degree from the position of the slide door is provided, and the door position sensor unit 9 generates an abnormality such as a half door state of the slide door or occurrence of pinching. When detected, a buzzer drive unit 10 for driving a buzzer for notifying the driver and passengers of an abnormality is provided. The sliding door ECU, which will be described later, derives the opening / closing speed of the sliding door from the time change of the sliding door position (door opening) detected by the door position sensor unit 9.

  Further, as shown in FIG. 1, a slide door ECU 11 having a microcomputer configuration is provided. Based on the signals from the sensor units 1 to 3, 5, 9 and the switches 5 to 7, the slide door ECU 11 is provided. The door opening / closing means 8 is controlled, and the buzzer driving unit 10 is controlled to generate various notification sounds.

  The sliding door ECU 11 has a vehicle speed detected by the vehicle speed sensor unit 1 being zero, and the foot brake sensor unit 2 is stepping on the foot brake while the shift lever of the vehicle is in the P (parking) range. When the parking brake sensor unit 3 detects that the parking brake is being operated, the sliding door ECU 11 detects the stop state of the host vehicle while the vehicle speed sensor unit 1 detects that the detected vehicle speed is not zero. The brake sensor unit 2 detects that the shift lever of the vehicle is outside the P (parking) range and that the foot brake is not depressed, or the parking brake sensor unit 3 does not operate the parking brake. Is detected by the sliding door ECU 11 Condition is detected.

  When the main switch 6 is turned on, the door opening / closing means 8 is controlled by the slide door ECU 11, the electromagnetic clutch 82 is connected to the sliding door opening / closing motor 81 of the door opening / closing means 8, and the sliding door opening / closing motor 81 is driven. The force is transmitted to the door driving mechanism 83 via the electromagnetic clutch 82, and the sliding door is slid by the door driving mechanism 83 to be automatically opened and closed.

  That is, the main switch 6 is turned on, the sliding door is fully open, and the sliding door ECU 11 detects that the host vehicle is in a stopped state, and an input of a closing operation signal based on the door closing operation of the door opening / closing switch 7 is received. If so, the normal closing control of the door opening / closing means 8 by the sliding door ECU 11 is performed, and the fully opened sliding door is driven in the closing direction. When the slide door moves to the fully closed position, the normal closing control of the door opening / closing means 8 is stopped. At this time, the buzzer driving unit 9 is controlled by the slide door ECU 11, and a buzzer sound for notifying that the normal closing control is being performed sounds in a predetermined pattern or tone.

  In addition, when the main switch 6 is turned on, the sliding door is fully closed, and the sliding door ECU 11 detects that the vehicle is in a stopped state, and an input of an opening operation signal based on the door opening operation of the door opening / closing switch 7 is input. If there is, the normal opening control of the door opening / closing means 8 by the sliding door ECU 11 is performed, and the sliding door in the fully closed state is driven in the opening direction. When the sliding door moves to the fully open position, the opening control of the door opening / closing means 8 is stopped.

  On the other hand, when the main switch 6 is turned off, the door opening / closing means 8 is controlled by the sliding door ECU 11, the electromagnetic clutch 82 is disconnected from the sliding door opening / closing motor 81, and the sliding door can be manually opened and closed. At this time, as described above, the opening / closing speed of the sliding door is equal to or lower than the target speed read by the electromagnetic clutch 82 with the target speed read from the memory as the upper limit according to the position of the sliding door (door opening). To be suppressed. Therefore, for example, when the main switch 6 is turned off in order to manually close the slide door in a state where the vehicle is stopped on an uphill, the electromagnetic clutch By 82, the closing speed of the sliding door is suppressed to a predetermined speed with the target speed as the upper limit.

  Further, when the main switch 6 is off and the manual opening / closing is selected, if the door opening / closing switch 7 is operated, the sliding door ECU 11 detects that the user has performed the door opening / closing operation. Then, the upper limit target speed is obtained by adding a fixed value to the target speed when the sliding door ECU 11 detects that the door opening / closing switch 7 is not operated and the sliding door ECU 11 detects no door opening / closing operation by the user. Is set high. Here, the detection of the presence or absence of the door opening / closing operation by the user of the slide door ECU 11 corresponds to the detection means in the present invention. In addition to the addition as described above, a predetermined target speed is stored in a memory that previously stores a high target speed in addition to the low target speed, and the door opening / closing operation is performed. Accordingly, the high target speed and the low target speed may be switched and selected.

  More specifically, as shown in FIG. 3, assuming that the sliding door is closed from the fully open state, when the sliding door is manually moved slightly from the fully open position to the closing direction, the door opening / closing operation by the user is performed. When the presence is detected by the sliding door ECU 11, the target speed from that point to the fully closed state is switched to a speed V2 higher than the speed V1 so far.

  As a result, for example, when the sliding door is manually closed from a fully opened state when the vehicle is stopped on a flat road without an inclination, the opening / closing speed of the sliding door is as shown by the solid line in FIG. It remains zero until it is detected that there is an operation, and after detecting that there is a door opening / closing operation, it changes so that the high target speed V2 is suppressed to the upper limit. On the other hand, when the sliding door is manually closed from the fully open state when the vehicle is stopped on an uphill, the opening / closing speed of the sliding door is detected as indicated by the solid line in FIG. 4B. By the natural fall, the speed of the sliding door gradually increases with the target speed V1 as the upper limit, and changes so that the high target speed V2 is suppressed to the upper limit after the detection of the presence of the door opening / closing operation.

  Therefore, according to the above-described embodiment, when the main switch 6 is off and the manual opening / closing is selected, the slide door ECU 11 detects that there is a door opening / closing operation (operation of the door opening / closing switch 7) by the user. Then, the target speed, which is the upper limit of the opening / closing speed of the sliding door, is switched higher by the sliding door ECU 11 than when the door opening / closing switch 7 is not operated and the sliding door ECU 11 detects that there is no door opening / closing operation by the user. Therefore, priority is given to the door opening / closing operation based on the intention of the user to open and close the slide door quickly, and the control of the opening / closing speed of the sliding door can be eased and the opening / closing speed of the sliding door can be increased. The sliding door can be opened and closed quickly on the street.

At this time, if it is detected that the user opens / closes the door, the target speed can be switched high, but the upper limit is set for the opening / closing speed of the sliding door. It can be prevented from becoming too fast.

  In the above-described embodiment, the case where the slide door is manually moved from the fully open state to the closing direction has been described. However, the same effect can be obtained even when the slide door is manually moved from the fully closed state to the opening direction. be able to.

  The present invention is not limited to the above-described embodiment, and various modifications other than those described above can be made without departing from the spirit of the present invention. For example, the suppression means is not limited to that configured by the electromagnetic clutch 82 and the slide door ECU 11 described above.

  Further, for example, when the main switch 6 is turned off and manual opening / closing is selected and the fully opened slide door is manually closed, as described above, the presence / absence of the door opening / closing operation by the user is detected by the slide door ECU 11, and the sliding door is opened / closed. After the target speed, which is the upper limit of the speed, is switched to the speed V2 higher than the speed V1, the sliding door is opened when the door opening degree by the door position sensor unit 9 becomes a predetermined opening degree close to full closing. Control may be performed to return the target speed, which is the upper limit of the opening / closing speed, to the speed V1.

  As a modified example, when the main switch 6 is turned off and manual opening / closing is selected and the fully opened sliding door is manually closed, the sliding door ECU 11 detects the presence of the door opening / closing operation by the user as described above. As shown in FIG. 5, after the target speed, which is the upper limit of the opening / closing speed of the sliding door, is switched to the speed V2 higher than the speed V1, the sliding door that is moving in the closing direction is stopped before it is fully closed. When the sliding door opening / closing speed drops below the speed V1 as shown by the solid line in the figure, when the sliding door stops, the sliding door ECU 11 again determines whether the user has detected whether the door opening / closing operation has been performed. If detected, the target speed may be reset to the speed V2.
