The invention discloses a four-motor wheel drive control system based on an electric formula car, which is connected to a vehicle control unit through a power CAN (Controller Area Network) and a data CAN, and the power CAN performs direct data transmission from the vehicle control unit to a motor controller through an accelerator pedal; the data CAN feeds back various sensor data including the SOC state of the battery box and the bus output current and voltage to the vehicle control unit, through the arrangement mode, the purpose of efficiently controlling the formula car is achieved, the running stability of the formula car is improved, and the service life of the formula car is prolonged. Therefore, the motor performance can be improved as much as possible under the condition that the total consumed power of the four motors meets target power following.

    本发明公开了一种基于电动方程式赛车的四电机轮边驱动控制系统,本发明通过动力CAN和数据CAN连接于整车控制器上,且动力CAN通过油门踏板到整车控制器到电机控制器进行直接数据传输,数据CAN通过将各种传感器数据包括电池箱的SOC状态、母线输出电流与电压进行反馈给整车控制器,通过上述设置方式,实现高效对方程式赛车进行控制的目的,且提高方程式赛车的运行稳定性,从而能够在四电机总消耗功率满足目标功率跟随情况下尽可能提高电机性能。
