The invention provides an electric driving method and an electric driving system for a vehicle, and relates to the field of vehicle electronic devices. The electric driving method comprises the stepsof collecting an accelerator pedal opening degree, a brake pedal opening degree, a vehicle speed/motor driving rotating speed, a driving mode, gear information, a vehicle body electronic stability control system state and a brake anti-lock braking system state of a vehicle in real time; obtaining a motor request torque according to a smaller one of a first motor request torque and a second motor request torque; and making the vehicle enter a corresponding working state according to the accelerator pedal opening degree, the brake pedal opening degree, the driving mode, the gear information, thevehicle body electronic stability control system state and the brake anti-lock braking system state, and controlling a motor output torque of the vehicle or controlling the output torque of the motorto be zero according to the motor request torque. The electric driving method can improve an energy utilization rate of the vehicle.
本发明提供一种用于车辆的电驱动方法和电驱动系统,涉及车辆电子器件领域。电驱动方法包括:实时采集车辆的加速踏板开度、制动踏板开度、车速/电机驱动转速、驾驶模式、挡位信息、车身电子稳定控制系统状态及制动防抱死系统状态;根据第一电机请求转矩和第二电机请求转矩中较小者获得电机请求转矩;根据加速踏板开度、制动踏板开度、驾驶模式、挡位信息、车身电子稳定控制系统状态及制动防抱死系统状态控制车辆进入相应的工作状态,并根据电机请求转矩控制车辆的电机输出转矩或控制电机的输出转矩为零。本发明的电驱动方法能够提高车辆能量利用率。
