Detailed description of the invention
In order to there be understanding clearly to technical characteristic of the present utility model, object and effect, now contrast accompanying drawing and detailed description of the invention of the present utility model is described, label identical in the various figures represents identical parts.For making simplified form, only schematically show the part relevant to utility model in each figure, they do not represent its practical structures as product.
As shown in Figure 1, 2, 3, the utility model is pure electric coaching vehicle control, comprise entire car controller 1 and battery 2, be provided with battery management system BMS13 in battery 2, battery charger 3, battery management system BMS13, electric machine controller 4 are connected by car load high-voltage conducting wires successively with motor 5; Battery charger 3, battery management system BMS13, electric machine controller 4, entire car controller 1 are connected by CAN line successively with combination instrument 6; Entire car controller 1 is connected with brake pedal 8 with efp 7 respectively by acquisition of signal line; 12V power supply 10 is connected with key switch 9 by primary cable, and key switch 9 is with brake pedal 8, efp 7, battery management system BMS13, battery charger 3, entire car controller 1, be connected by car load primary cable between electric machine controller 4 and combination instrument 6; Be provided with magslip 11 in motor 5, motor 5 is connected with five grades of change speed gear boxs 12.
Principle of work of the present utility model is as follows: when starting the vehicle, key switch 9 is adjusted to ON shelves by driver, 12V power supply 10 is connected, and entire car controller 1 carries out communication by CAN line and electric machine controller 4, battery management system BMS13, and whether detection battery 2 and electric machine controller 4 have fault to exist; When key switch 9 is adjusted to START, i.e. vehicle ignition, entire car controller 1 makes the main contactor in battery 2 close by CAN line, electric machine controller 4 positive and negative busbar is connected with high pressure, signal on entire car controller 1 Real-time Collection efp 7 and brake pedal 8, and by the signal collected by sending torque command by CAN alignment electric machine controller 4 after parsing, calculation process, electric machine controller 4 starts drive motor 5 and operates after receiving torque command, thus driving change speed gear box motion, vehicle starts normal traveling.
The utility model gathers the current state of signal on efp 7, brake pedal 8, the current information of battery 2, motor 5 by entire car controller 1 after, torque rating is converted to by parsing, computing, send to electric machine controller 4 by CAN line again, thus realize the function of conventional fuel oil car engine.Entire car controller 1 sends the signal of direction running to electric machine controller 4, the advance of vehicle or return back through five grades of change speed gear boxs 12 and realize, thus is consistent with conventional fuel oil car.
If when starting vehicle, driver does not operate efp 7, electric machine controller 4 can make motor 5 be in idling mode by its inner software arranged, and completes the startup of car load.If electric machine controller 4 or battery 2 break down, entire car controller 1 is uploaded to combination instrument 6 by CAN line.
The utility model can realize the idling function of car load by electric machine controller 4, and when driver's operated clutch and efp 7 exercise not harmony, by the extinction function of the software simulating electronlmobil in electric machine controller 4.Concrete operations are: definition N1 (ox. rice) be during battery-driven car idling electric machine controller 4 export maximum torque, definition N2 (ox. rice) for electric machine controller 4 export real-time torque rating, the rotating speed that n1 (rpm) is motor during idling 5, the rotating speed that n2 (rpm) is motor during idling flameout 5, when electric machine controller 4 positive and negative busbar voltage has high input voltage, the vdc of battery 2 is converted to the three-phase line end that alternating-current voltage/AC voltage is input to motor 5 by electric machine controller 4, thus make motor 5 be in operative condition, i.e. battery-driven car idling mode, now electric machine controller 4 is adjusted to rotating speed control, the rotating speed of motor 5 is made to remain on n1 by regulation output moment of torsion N2, if in starting process, because vehicle load is excessive or parking brake is forgotten and put down, the rotating speed of motor 5 still cannot be made to remain on n1 when the moment of torsion N2 that electric machine controller 4 exports in real time is greater than N1, and motor 5 real-time rotate speed is when being less than n2, battery-driven car now then stops working, electric machine controller 4 is quoted flame-out fault upload combination instrument 6 and is shown.
During normal startup, the actual output torque N2 of electric machine controller 4 is at 15 Ns. rice and-15 Ns. regulate between rice, motor 5 actual speed is operated at 500 turns of per minutes and 80 turns of per minutes, finally maintain 270 turns of per minutes, when reaching setting speed, motor 5 is in stable idling mode, and now namely battery-driven car represents and start successfully, and trouble free is quoted.If when student's mal starts, as started rear put in the first speed but forgetting RELEASE PARKINGBRAKE, controller actual output N2 can increase always, motor 5 rotating speed also cannot be made to remain on 270 turns of per minutes until be increased to setting torque peak N1, and battery-driven car stops working when motor 5 rotating speed is reduced to setting value n2, electric machine controller 4 is quoted flame-out fault and is uploaded to combination instrument 6, and prompting driver break down.
The utility model has speed limiting function, controls the maximum speed of revolution of motor 5 by electric machine controller 4, thus controls the maximum speed of revolution of vehicle.Under electric machine controller 4 can make motor 5 be operated in drive pattern or braking mode situation, curve motor 5 rotating speed being declined by software is consistent with driving engine, thus without pause and transition in rhythm or melody sense when switching gear.
The utility model has braking priority function, if when entire car controller 1 receives the signal on brake pedal 8 and the signal on efp 7 simultaneously, entire car controller 1 will send torque command will not to electric machine controller 4, invalid depending on efp 7, bring danger to prevent student's faulty operation.
Entire car controller of the present utility model 1 and electric machine controller 4, battery management system BMS13 carry out communication, and the information of each parts of Real-time Collection is also carried out diagnosis and judged whether each parts have fault, thus the safe operation of guarantee vehicle.Entire car controller 1 is communicated with electric machine controller 4, battery management system BMS13 in real time by CAN line, monitors, diagnoses the information of each parts in real time, occurs that different stage fault carries out classification process, improve the safety of car load to parts.When entire car controller diagnose out parts to there is minor failure such as motor temperature is higher time, entire car controller 1 limits sending to the torque rating of electric machine controller 4, and vehicle can be at low speed; When entire car controller 1 diagnoses out parts to there is major failure as there is electric leakage, entire car controller 1 is disconnected being made the main contactor in battery 3 by CAN line, to ensure the safety of car load.
Battery charger 3 of the present utility model can charge to battery 2, battery charger 3 is communicated by CAN line with battery management system BMS13, the time in student's nooning or evening is utilized to charge to battery 2,200km continual mileage can be reached after battery 2 is full of electricity, meet driving school's use of a day.
Detailed description is above only illustrating for feasibility embodiment of the present utility model; they are also not used to limit protection domain of the present utility model, allly do not depart from equivalent implementations that the utility model skill spirit does, change and transformation all should be included within protection domain of the present utility model.
