The invention relates to an anti-slip control system for an electric automobile. The anti-slip control system comprises a motor controller, a motor connected with the motor controller, an accelerator pedal, an accelerator pedal sensor, a brake pedal, a brake pedal sensor, a motor current sensor and a rotary transformer, accelerator pedal signals, brake pedal signals, motor current data signals, motor rotating speed data signals, rotary transformer signals and other data of the motor controller are all collected and processed by the DSP data processor, and the motor is controlled through the motor controller. Signals are sent to the DSP chip data processor through all the sensors, the ramp condition of the vehicle is judged, then the svpwm duty ratio and the driving current are adjusted through the controller, the motor driving torque counteracts the torque borne by the vehicle due to the gradient, the vehicle is prevented from sliding, traffic accidents are greatly reduced, and the driving safety of the vehicle is improved. And meanwhile, the operation burden of restarting after the driver brakes during uphill and downhill is reduced.
本发明涉及一种电动汽车防溜车控制系统,包括电机控制器,与电机控制器连接的电机、油门踏板及油门踏板传感器、刹车踏板及刹车踏板传感器、电机电流传感器、旋转变压器;所述油门踏板信号、刹车踏板信号和电机电流数据信号、电机转速数据信号、旋变信号,以及电机控制器的其他数据均由DSP数据处理器采集处理,通过电机控制器控制电动机;通过各个传感器将信号发送到DSP芯片数据处理器,判断车辆的坡道状况,进而通过控制器来调整svpwm占空比,调节驱动电流大小,使得电机驱动力矩抵消掉车辆因坡度所受到的力矩,防止车辆溜车,大大减少了交通事故的发生,同时减少驾驶人员在上下坡刹车后再起动时的操作负担。
