The invention discloses a gear selecting and shifting mechanism self-learning detecting control system and method. The system comprises a CAN communication circuit, a voltage and current detecting circuit, a PLC man-machine interaction module, a master control module, a motor load circuit and a position detecting circuit, and a control cabinet is internally provided with a switch circuit, the voltage and current detecting circuit and a voltage conversion circuit. According to the method, positive and negative rotation of a gear selecting motor and a gear shifting motor are controlled, the gearselecting sensor voltage value and the gear shifting sensor voltage value are obtained, the mechanism running position is identified by detecting voltage changes of sensors, the sensor voltage valuesof the mechanism in all gears are recorded, and identification of the gears is achieved. The gear selecting and shifting mechanism self-learning detecting control system and method have the beneficial effects that by controlling the mechanism running tracks, man-made reading errors are eliminated; and by means of running of a process control mechanism in the gears, frequent and repeated operationof each speed changing box by an engineer is avoided, continuous and automatic running can be achieved, and the standardization working efficiency of the speed changing box mechanism is greatly improved.
Description
technical field [0001] The invention relates to a system and method for self-learning detection and control of a gear selection and shift mechanism, and belongs to the technical field of detection equipment for pure electric vehicles. Background technique [0002] In pure electric vehicles, the reason why the vehicle can automatically shift gears is because the driver lowers the position of the accelerator during work. The vehicle's vehicle control system can command the automatic gear shift system to work, and the gear selection mechanism is to achieve this. The direct executor of the function, it plays an important role in the operation of the vehicle. It directly determines whether the vehicle can perform normal up-and-down gears. Run in the required gear, realize the power output direction and speed ratio conversion, control the vehicle to move forward or backward and the driving speed. An important guarantee for output. It is of great significance to match the car's g...
