The invention relates to a motor torque compensation control method based on battery parameter analysis. The method comprises the steps of 1, building a pure electric vehicle torque control model, and enabling an electric vehicle torque controller to determine a driving torque according to a driving torque instruction, wherein the driving demand torque is expressed as a function composed of the opening degree of an accelerator pedal, the opening degree change rate of the accelerator pedal, the vehicle speed and the SOC of a power battery; and 2, according to a torque control strategy of the pure electric vehicle, adopting a driving mode fuzzy controller, dividing the driving mode of the electric vehicle into a common mode and an acceleration mode, and introducing driving compensation torque in the acceleration mode. According to the method, the appropriate driving mode can be selected under different acceleration requirements, the electric quantity of the power battery is utilized more reasonably, the acceleration performance of the electric vehicle is improved, the time required for acceleration is shortened, and the driving operation feeling and the endurance mileage of the electric vehicle are improved.

    本发明涉及的是基于电池参数解析的电机转矩补偿控制方法,其包括:步骤一、建立纯电动汽车转矩控制模型,电动汽车转矩控制器根据驱动转矩指令确定驱动转矩,驱动需求转矩表示为由加速踏板开度及其开度变化率、车速和动力电池SOC组成的函数;步骤二、纯电动汽车转矩控制策略,采用驱动模式模糊控制器,将电动汽车的驱动模式分为普通模式和加速模式,并在加速模式下引入驱动补偿转矩。本发明能在不同的加速需求下选择合适的驱动模式,更加合理的利用动力电池电量,并且提升了电动汽车的加速性能,缩短了加速所需时间,提高了电动汽车的驾驶操作感和续航里程。
