The invention provides a pure electric vehicle torque compensation method and system, and the method comprises the steps: obtaining the opening degree change rate of an accelerator pedal, and judging whether a torque compensation strategy condition exists or not based on the opening degree change rate of the accelerator pedal; if the torque compensation strategy condition is met, the compensation torque is obtained through table look-up according to the accelerator pedal opening change rate and the current vehicle speed; and adding the compensation torque and the basic torque to obtain required torque, and outputting the required torque when the required torque meets upper and lower limit limits of an accelerator. According to the scheme, the power response speed of the pure electric vehicle in a sudden acceleration scene can be improved, and the power requirement of a driver is met.

    本发明提供一种纯电动车辆扭矩补偿方法及系统,该方法包括:获取油门踏板开度变化率,基于油门踏板开度变化率判断是否扭矩补偿策略条件;若满足扭矩补偿策略条件,则根据油门踏板开度变化率和当前车速,查表获取补偿扭矩;将补偿扭矩与基础扭矩相加得到需求扭矩,当需求扭矩满足油门上下限限制,则输出需求扭矩。通过该方案可以提升纯电动车辆急加速场景下动力响应速度,满足驾驶员的动力需求。
