The invention relates to a torque vector control method for a pure electric front-drive vehicle and a storage medium. The method comprises the following steps that the vehicle information of a current vehicle and the road surface information of a driving road surface are obtained; the required torque of the driver is obtained according to the vehicle information, and whether the required torque of the driver is positive or not is judged; if yes, whether the vehicle is on a low-adhesion road surface or not is judged according to the road surface information; if yes, whether the vehicle starts to steer is judged according to the vehicle information; if yes, whether vehicle steering is sharp turning or not is judged; if yes, an intervention torque is calculated; the required torque of the driver is intervened according to the calculated intervention torque to obtain the final output torque of the current vehicle; and the vehicle is controlled according to the final output torque. The method is advantaged in that the vehicle suddenly turns according to the final output torque, so stability of the vehicle during turning on a low-adhesion road surface is improved.

    本发明涉及一种纯电动前驱车扭矩矢量控制方法及存储介质,所述方法包括以下步骤:获取当前车辆的车辆信息及行驶路面的路面信息;根据车辆信息获取驾驶员的需求扭矩,并判断驾驶员的需求扭矩是否为正;若为正,则根据路面信息判断车辆是否处于低附着力路面;若是,则根据车辆信息判断车辆是否开始转向;若是,则判断车辆转向是否为急转弯;若是,则计算出干预扭矩;根据计算出的干预扭矩对驾驶员的需求扭矩进行干预得出当前车辆的最终输出扭矩;根据最终输出扭矩对车辆进行控制。让车辆根据最终的输出扭矩进行急转弯,提高车辆在低附着力路面转弯时的稳定性。
