Study on Control Process of Automatic Mechanical Transmission System for Pure Electric Bus

Abstract:

The vehicle driveline of pure electric bus based on the automatic mechanical transmission (AMT) was introduced and the rationality and necessity of using AMT in electric bus was discussed. The control network structure of vehicle driveline was built in this paper. According to the evaluation standards of automatic gear shifting, that is, the shift time and shift jerk, the optimum control strategy of automatic gear shifting was proposed in terms of the principle and method of adjusting torque and speed of motor. The experimental results indicate that, by the use of the developed gear-shifting control system for pure electric bus with AMT, the coordination control of gear-shifting process between AMT and synchronous motors based on the controller area network (CAN) bus technology can be realized. Consequently, the shifting quality can be improved thus to achieve the predetermined effect.
