The invention provides a method and a device for controlling the power assisting function of a vehicle. The method comprises the steps that a current working mode fed back by a vehicle control unit is obtained; the working modes comprise a pure electric mode, a traditional mode and a hybrid mode; if the obtained working mode is a traditional mode or a hybrid mode, a dynamic power assisting function is executed, and the execution of the dynamic power assisting function comprises the steps that a motor dynamic power assisting torque demand is sent to a motor, and an actual motor dynamic power assisting torque returned by the motor is received; and the power performance of the engine is compensated according to the actual dynamic power-assisted torque of the motor. According to the dynamic torque compensation method, device, the whole vehicle controller controls the motor with the fast response to conduct dynamic torque compensation, the whole vehicle requirement can be met in a short time, the whole vehicle acceleration performance is improved, and the driving feeling is improved.

    本发明提供一种汽车助力功能的控制方法及装置,该方法包括:获取整车控制器反馈的当前的工作模式;所述工作模式包括:纯电动模式、传统模式和混动模式;若获取到所述工作模式为传统模式或混动模式时,执行动态助力功能,其中,所述执行动态助力功能包括:向电机发送电机动态助力扭矩需求,并接收电机返回的实际电机动态助力扭矩,根据所述实际电机动态助力扭矩对发动机动力性能进行补偿。本发明中,实现由整车控制器控制响应较快的电机进行动态扭矩补偿,能够在较短的时间内满足整车需求,提高整车加速性,提高驾驶感受。
