Research on Braking Efficiency Simulation of Electric Vehicle Based on AMESim-Simulink Software

在分析了整车制动控制数学模型的基础上,合理分配前后轴制动力矩,并制定了整车制动力分配与恒定再生制动力矩策略,根据驾驶员的制动意图识别所需制动强度。利用AMESim-Simulink软件搭建联合仿真模型,仿真结果表明:采用恒定再生制动力矩策略,可以满足汽车的制动效能要求,实现停车制动功能。

Based on the analysis of the mathematical model of the vehicle braking control,the braking torque of the front and rear axles was reasonably distributed,and the strategy of the vehicle braking force distribution and constant regenerative braking torque was developed.The required braking intensity was identified according to the braking intention of the driver.According to the above control strategy,a co-simulation model was built by AMESim-Simulink.The simulation results show that the constant regenerative braking torque strategy can meet the braking efficiency requirements of the vehicle and realize the braking function.
