The invention provides a pure electric heavy truck retarder torque control method. The pure electric heavy truck retarder torque control method is characterized in that a central control module, a retarder control module, a drive control module, a brake control module, a vehicle speed detection module and a road slope detection module are included; the control method comprises the steps that the central control module obtains the accelerator pedal torque according to the accelerator pedal opening degree and the vehicle speed, then obtains the retarder torque according to the road slope, the vehicle speed and the retarder torque coefficient, and then determines the braking torque according to whether the retarder state is activated or not; and finally, the motor demand torque is obtained according to the accelerator pedal torque, the brake torque and the whole vehicle speed ratio. By the adoption of the control method, the driving safety and the driving comfort of the pure electric heavy truck can be greatly improved.

    本发明提供了一种纯电重卡缓速器扭矩控制方法,其特征在于:包括中央控制模块、缓速器控制模块、驱动控制模块、制动控制模块、车速检测模块和路面坡度检测模块;所述控制方法包括:中央控制模块根据油门踏板开度和车速获取油门踏板扭矩,然后根据路面坡度、车速和缓速器扭矩系数获取缓速器扭矩,然后根据缓速器状态是否激活确定制动扭矩,最后根据油门踏板扭矩、制动扭矩、整车速比获取电机需求扭矩。采用本申请的控制方法,能大大提高纯电重卡行驶的安全性和驾乘舒适度。
