Based on described embodiment 1, described collecting device can comprise: manual accelerator control voltage transducer, foot throttle pedal sensor, load selector switch, engine start trigger switch, oil pressure sensor, accelerator pedal sensor and crankshaft rotational speed sensor etc.Certainly, when monitoring for Motor Vehicle, used collecting device is not limited to above-mentioned cited sensor or switch, and sensor or switch that these can concrete setting will be used according to the running state of the actual Motor Vehicle that will monitor are enumerated here no longer one by one.On embodiment 1 basis, for different collecting devices, carry out the detailed description of the adjustment of different Motor Vehicle real-time running states, be described as follows:
1, two Throttle Opening Control of Motor Vehicle
The value of the pedal sensor that the magnitude of voltage that controller reception manual accelerator control is corresponding and foot throttle are corresponding, the magnitude of voltage that described manual accelerator control is corresponding is a upper voltage limit value, is used for determining maximum engine speed.Can determine the engine speed corresponding to value of the pedal sensor that described foot throttle is corresponding according to upper voltage limit value corresponding to described manual accelerator control, then regulate actual engine speed to the engine speed corresponding to value of pedal sensor corresponding to described foot throttle by ratch.The corresponding a plurality of different voltage gears of manual accelerator control, such as, manual accelerator control can corresponding 0-5V the voltage gear, when manual accelerator control is operated personnel adjustment when the 4V and during 5V, the different corresponding maximum engine speeds of voltage are different on the one hand, suppose that maximum (top) speed corresponding to 4V is that maximum (top) speed corresponding to 1600,5V is 2000; On the other hand, in the different situation of magnitude of voltage corresponding to manual accelerator control, even the value of pedal sensor corresponding to foot throttle is identical, such as all being 50%, still corresponding engine speed is different, such as, the rotating speed of correspondence 50% is 800 during 4V, and the rotating speed of correspondence 50% is 1000 during 5V.
2, the control of many power characteristics
The driver selects the load condition of vehicle according to the actual loading situation of vehicle (such as bulldozer), described load condition comprise underloading, in carry and heavy duty, in the practical operation, can realize that unequally loaded selects with three polymorphic switches.The in a single day selected a kind of load condition of driver, the switch that this state is corresponding will be connected, and produces the switching value signal, and described switching value signal can be represented by voltage (perhaps simply being interpreted as the high-low level signal).Controller is determined the load condition of vehicle according to the switching value signal that receives, be external characteristics oil mass MAP curve corresponding to this condition selecting.Described MAP curve has identified transmitter rotating speed and oil spout the relationship between quantities, and described fuel injection quantity is maximum spout oil mass corresponding under certain rotating speed.Determine that external characteristics oil mass MAP curve corresponding to different conditions is in order to save the protection of oil consumption and motor; give an example; such as; suppose for underloading, in carry and heavy condition; fuel injection quantity in MAP curve corresponding to same rotating speed is respectively 50 milligrams, 80 milligrams and 100 milligrams; determine after the fuel injection quantity of vehicle; can send control command control fuel injection quantity; to guarantee that vehicle is when normally moving; under different load conditions; fuel injection quantity does not exceed the maximum spout oil mass in real time, saves oil consumption, the protection motor.There is not in the prior art the selection of MAP curve, the driver is in the process of steering vehicle, can't switch the MAP curve, vehicle operating just may occur under heavy condition in this, and the fuel injection quantity of car load is to come oil spout according to the fuel injection quantity under the light condition, the power that motor produces is inadequate, and the situation of over-emitting black exhaust will occur, and not only fuel consumption is large but also also larger to the loss of motor).
3, engine start control and protection
In order to protect motor; can control engine start; such as; can set in advance very first time threshold value; if the driver inserts key and turns key to the state of ato unit; engine start switch is triggered, and the gear in the controller control Starter stretches out, and drives engine operation by Starter; described very first time threshold value is key and is inserted into maximum duration between the engine operation; in at this moment, no matter whether motor starts successfully, reach time threshold after; controller disconnects the control to cranking-motor relay; starter gear is regained, engine start trigger switch open circuit, and starting stops.The minimum interval (the second time threshold) of adjacent twice ato unit equally also can be set, like this can be when engine failure, the motor loss of avoiding the frequent starting motor to bring.
Preferably; before ato unit, can set the engine start protective condition; such as, neutral position switch whether indicate neutral be vehicles failed start, to motor pre-for machine oil whether finish, safety strip (whether snap close inserts) whether effectively (whether the driver fastens seat belts).Certainly, in actual applications, can also according to the needs of practical application scene, the condition of different protections be set.In the situation that above-mentioned condition all satisfies, the start-up course of motor is just effective.Wherein, the pre-of motor finished before engine start for machine oil, refer to before the so-called engine start, when turning the state that powers on for controller after key inserts (key can be selected different gears after inserting), active controller, controller output control command is so that start for oil pump in advance and supply in advance machine oil for motor, when oil pressure sensor indication pre-exceeds the preset pressure threshold value for engine oil pressure, can determine to supply in advance the machine oil process to finish.Preferably, can't finish the pre-machine oil that supplies for fear of pre-breaking down for oil pump, make engine oil pressure can't reach the preset pressure threshold value always, can also arrange pre-for the machine oil time threshold, engine oil pressure does not also reach the preset pressure threshold value when reaching pre-confession machine oil time threshold, then send fault warning, indication is pre-breaks down for machine oil.
Meanwhile, the idling of motor can also be set, concrete can arrange according to the loading condition of vehicle, such as, take air-conditioning as example, if air-conditioning is not worked, it is low a little that the rotating speed that then engine idle is corresponding can arrange, if air-conditioning work then improves the rotating speed of motor under idling mode accordingly, such as adding 100 on original idle speed value basis.Described engine idle indication is when vehicle speed is zero, and motor is output power not, but can keep the engine speed value that vehicle runs well.According to different loads, the occurrence of idling can also specifically arrange, and does not do concrete restriction here, and above-mentioned each numerical value all is convenient to the understanding to this programme as an example, should not regard the restriction to this programme protection domain as.
4, adjustable full distance speed regulating rate
For the ease of the understanding to adjustable full distance speed regulating rate, the below describes for example, controller receives the value (corresponding engine speed) of accelerator pedal sensor and crankshaft rotational speed sensor, the value of supposing accelerator pedal sensor is 50%, for the vehicle that reality is used, different accelerator pedal values is the engine speed of corresponding certain limit.Value and the engine speed of supposing accelerator pedal in the Vehicle Driving Cycle process are mated, if vehicle meets obstructions suddenly, engine speed might be larger depart from the coupling rotating speed, at this moment, if corresponding engine speed is higher than the corresponding tachometer value of motor max. output torque during normal vehicle operation, then adopt first to set rotational speed rate engine speed is regulated, such as can be with the adjustment of rotational speed after departing to departing from former rotating speed 5%-8%(speed governing rate); If corresponding engine speed is lower than the corresponding tachometer value of motor max. output torque during normal vehicle operation, adopt the second setting rotational speed rate that engine speed is regulated, such as, can be with the adjustment of rotational speed after departing to departing from former rotating speed 3%-5%.The meaning of described speed governing rate is, suddenly increase or unexpected when less in vehicle load, the wave range of engine speed and the proportionate relationship of former tachometer value, wave range is the smaller the better, is 1000 to turn such as, former rotating speed, the larger load of prominent chance, rotating speed drops to 970 and turns, and this moment, the speed governing rate was 3%, and motor also need to strengthen oil spout in the short time and make and rise to 1000 in the engine speed and turn.Preferably, can exchange the speed subsection setup by the VEC6800 calibration software.As for the size of speed governing rate, can specifically arrange according to the practical application scene in actual applications, be not construed as limiting here.
In the monitor procedure to motor, engine speed is a very important parameter, Security for assured plan, preferably, described crankshaft rotational speed sensor can arrange a plurality of, there is a crankshaft rotational speed sensor to break down and to use, such as open circuit, can starts backup sensors and work on.Because if do not start the words of backup sensors, controller then can't obtain real engine speed, this Time Controller starts the acquiescence engine speed of preserving, if such as this moment vehicle be in heavy condition, if the acquiescence engine speed can not provide enough power for vehicle, can cause outside the over-emitting black exhaust, also can damage motor.
5, to other controls of Motor Vehicle
Here illustrate the otherwise control of Motor Vehicle in the mode of enumerating, such as, controller can also receive air filter and stop up the switching value signal, when the resistance of air filter reaches predetermined threshold value, force the resistance switch on, to controller transmit button amount signal, controller is reported to the police, and indication air filter resistance is crossed major break down.
When the moisture height that filters out in the oil exceeds preset height, trigger the switching value signal of corresponding oil-water separation level sensor, controller is reported to the police, and the indication water content in oil is crossed multiple faults.
Charge heating is controlled, (controller control inlet air heating relay), after controller powers on (if motor does not start), the coolant temperature that can obtain according to cooling-water temperature transmitter, if the coolant temperature of obtaining is lower than the preset temperature lower limit, then control the inlet air heating relay closes, the inlet air heating grid heats; If engine start in heating process, then stopped heating process immediately; If motor starts, judge then whether the coolant temperature that cooling-water temperature transmitter obtains is higher than the preset temperature CLV ceiling limit value, if be higher than, then reduce accordingly the concurrent warning information that is out of order of fuel injection quantity of Motor Vehicle according to the real time temperature of cooling liquid.Give an example, suppose that the coolant temperature CLV ceiling limit value is 95 degree, when coolant temperature reaches 95 when spending; on the one hand controller starts alarm, on the other hand, multiply by at this moment one on the basis of fuel injection quantity less than 1 Weighting factor; make fuel injection quantity less, such as multiply by 90%, along with the rising of coolant temperature; continue to reduce Weighting factor, such as, when temperature reaches 100 when spending; can multiply by 10%; to reduce fuel injection quantity, temperature continues to be increased to setting value, then stops oil spout and carries out the motor protection.
If the speed of a motor vehicle of described Motor Vehicle is in zero and object time, the value of the value of manual accelerator control voltage transducer and foot throttle pedal sensor does not change, and then the control engine state is adjusted to idle; When the value of the value of manual accelerator control voltage transducer and/or foot throttle pedal sensor changes, then adjust actual engine speed according to the value of manual accelerator control voltage transducer and the value of foot throttle pedal sensor.
Rapid Thermal car that can the controller motor-car, such as, controller is adjusted the idling of motor according to engine coolant temperature, reach Rapid Thermal car purpose.Such as, idle speed value under the cold machine state is set is 700 and turn, the idling during so corresponding Rapid Thermal car can be set to 900 and turn.Such as, water temperature is-20 ℃, then idle speed value is 750 to turn, water temperature is 10 ℃, idling is 650 to turn, water temperature be 30 ℃ and more than, then idle speed value is 600 to turn.
Be understandable that, in the specifying of above-mentioned control to Motor Vehicle, label 1-5 does not represent the sequencing of controlling method, and just difference is to the difference control of Motor Vehicle.Described several controlling method is for the present embodiment being made an explanation, also only illustrating, and is not the restriction to controlling method, can not regard the restriction to protection domain of the present invention as.Wherein all threshold values all can arrange voluntarily according to the practical application scene.
When breaking down, for concrete Type of alarm, embodiments all among the present invention all do not do restriction, in practical operation, can adopt the mode that connects tutorial light at the controller end, go out such as tutorial light and to be fault-free, tutorial light is bright for fault is arranged, can show that at different tutorial light places this tutorial light is used to indicate the fault at which position of vehicle, perhaps send signal to entire car controller by the CAN bus, be outputed in the instrument panel by entire car controller and show, preferably, also can adopt simultaneously above-mentioned dual mode, when avoiding certain indicating mode to break down, can't indication fault.Simultaneously, also can for controller arranges tutorial light, be used to indicate controller failure.Preferably, controller and CAN bus can adopt SAE J1939 protocol communication, and the data that will finally need to be fed back by entire car controller show at instrument panel.
Further, can also carry out record to fault, be convenient to the follow-up work personnel and check the historical failure situation.Further, ann reset can also be set, fault is eliminated if controller detects described fault after a period of time occurs, and then the indication of reporting to the police is resetted, if tutorial light is then controlled the state of tutorial light to unfaulty conditions.Because in the actual travel process, if sensor connects open circuit, the alarm of breaking down, and the road of Vehicle Driving Cycle jolts so that sensor is closed, namely is returned to normal working, this Time Controller can be controlled alarm indicator lamp and reset, and vehicle is normally moved.
For the ease of according to actual use condition, increase new function, the controller among the present invention can the reserved part interface, is convenient to follow-up Function Extension.
In above-mentioned description based on embodiment 1, can obtain technological scheme of the present invention, analyze by the running state data to each collecting device collection of receiving, judge the runnability of Motor Vehicle, the full distance speed regulating to motor, the selection of external characteristic curve have been realized, regulate the fuel injection quantity of oil sprayer, can calculate according to air inflow can the required fuel injection quantity of best combustion, reduces exhaust pollution.Under the prerequisite of guaranteed output, save oil consumption.Diagnose the fault that shows that Motor Vehicle exists by fault diagnosis switch and fault indicating lamp, can help the location of the quick failure judgement type of maintenance man and the position of breaking down.Having water tutorial light reminding driver to open switch in can be by oil when the moisture water level in the fuel oil transfinites bleeds off the water that filters out.Before engine start, can supply with machine oil to motor in advance for pump in advance by machine oil, start and to the protection of engine friction part with convenient.Before engine start, when coolant temperature is low, according to coolant temperature control inlet air heating relay the air in the suction tude is heated, be conducive to the cold start-up of motor.In engine operation, COOLANT TEMPERATURE is quoted the COOLANT TEMPERATURE fault, and reduces oil spout.Can realize the two Throttle Opening Control of car load and the total line traffic control function of CAN, fully change the present situation of the pure machinery control of engineering machinery high-power mechanical pump structure engine.
