The invention relates to a vehicle dragging torque control method and system and a vehicle. The method comprises the steps that S1, the transverse deceleration of the vehicle is compared with a preset first deceleration threshold value; s2, if the transverse deceleration exceeds the first deceleration threshold value, the limited recovery torque corresponding to the transverse deceleration is determined; s3, determining a corresponding recovery torque value of the vehicle according to the limited recovery torque; and S4, the dragging torque of the vehicle is adjusted to the recovery torque value through a vehicle control unit of the vehicle. According to the technical scheme, when the transverse deceleration of the vehicle is larger than the preset first deceleration threshold value, the limited recovery torque corresponding to the transverse deceleration at the moment is obtained according to the torque limiting diagram, and the vehicle adjusts the whole vehicle torque according to the limited recovery torque.

    本申请涉及一种车辆拖拽扭矩的控制方法、系统及车辆,方法包括:S1,将车辆的横向减速度与预设的第一减速度阈值进行比较;S2,若所述横向减速度超出所述第一减速度阈值,则确定与所述横向减速度对应的限制回收扭矩;S3,根据所述限制回收扭矩确定所述车辆的相应的回收扭矩值;S4,通过所述车辆的整车控制器将所述车辆的拖拽扭矩调节到所述回收扭矩值。本申请的技术方案,当车辆的横向减速度大于预设的第一减速度阈值时,根据扭矩限制图获取此时横向减速度对应的限制回收扭矩,车辆根据限制回收扭矩调整整车扭矩。
