The invention relates to the technical field of electric vehicle control, in particular to a control system and a control method for ramp auxiliary driving of an electric vehicle. The control system comprises a vehicle control unit VCU and a driving system; the vehicle control unit VCU is used for collecting vehicle CAN network signals including vehicle BMS system signals, MCU system signals, OBC system signals, accelerator pedal input signals, brake pedal input signals, gear input signals and hand brake input signals. The driving system comprises a motor controller MCU, a motor and a differential mechanism. The driving system executes different action responses in real time according to control instructions of a vehicle control unit VCU. The control instructions of the vehicle control unit VCU comprise a working mode, a request torque and an enable signal; according to the control method, by judging the acceleration of the vehicle, the situation that the vehicle mistakenly enters the anti-slip mode can be effectively reduced, the situation that the vehicle enters the anti-slip state is accelerated, the vehicle slip distance can be effectively reduced, and the comfort and safety of vehicle acceleration are improved.

    本发明涉及电动汽车控制技术领域,具体涉及一种电动汽车坡道辅助驾驶的控制系统及控制方法。控制系统包括整车控制器VCU和驱动系统;整车控制器VCU用于整车CAN网络信号的采集,包括整车BMS系统信号、MCU系统信号、OBC系统信号、加速踏板、制动踏板、档位、手刹输入信号的采集;驱动系统包括电机控制器MCU、电机、差速器,驱动系统实时根据整车控制器VCU的控制指令来执行不同的动作响应;所述整车控制器VCU的控制指令包括工作模式、请求扭矩、使能信号三种;所述控制方法通过对车辆加速度的判断可有效减少车辆误进入防溜坡模式和加快车辆进入防溜坡状态,可有效降低车辆溜坡距离,提供车辆加速的舒适性和安全性。
