Research on Nonlinear Driving Control and Driving Force Calibration of Pure Electric Vehicle

Abstract:

According to the main problems of nonlinear driving control and driving force calibration of pure electric vehicle, based on the research of permanent magnet synchronous motor control method, on the vehicle's driving force calibration techniques were studied, from the high efficiency and energy saving analysis of necessary driving force calibration, designed a new driving force calibration method, and drew the control curve of the accelerator pedal opening and the speed and the motor torque relationship between the three, and finally to pure electric self-developed to test platform for automotive related experiments. The experimental results show that, in the vehicle driving process, the driving force calibration technique compared with the previous calibration has better performance, while no obvious change of acceleration performance, the current value of the initial acceleration phase have been greatly decreased, could make the vehicle run more energy efficient, extended battery life and vehicle driving mileage.
