The vehicle traction control method specifically comprises the steps that when it is judged that a vehicle is in a slipping state at the next moment, the torque limiting value and the actual wheel torque are obtained, and the torque required by a driver is obtained through a whole vehicle controller; the torque limit value and the driver demand torque are analyzed and processed, and the final wheel demand torque is obtained; and according to the actual wheel torque and the final wheel demand torque, the wheel torque is adjusted, and the traction force of the vehicle is controlled. Data processing flows such as receiving of the wheel slip rate and the torque required by the driver and obtaining of the torque limit value are integrated in the same device instead of being dispersed to other devices, so that data transmission nodes are reduced, the data processing time is shortened, and the data processing efficiency is improved. The vehicle can respond in a short time, the traction force of the vehicle can be controlled, and the stability, comfort and other performance of the vehicle are improved.

    本发明公开了一种车辆牵引力控制方法和电机控制器,具体包括:当判定下一时刻车辆处于打滑状态时,获取力矩限值和车轮实际扭矩,以及通过整车控制器获取驾驶员需求扭矩;对所述力矩限值和所述驾驶员需求扭矩进行分析处理,获得最终车轮需求扭矩;根据所述车轮实际扭矩和所述最终车轮需求扭矩,对车轮扭矩进行调节,实现对车辆牵引力的控制。本发明通过将车轮滑移率和驾驶员需求扭矩的接收、以及力矩限值的获取等数据处理流程集成于同一器件内,而非将之分散至其他器件,以减少数据传输节点和减短数据处理时长,使得车辆能够在较短时间内响应并实现车辆牵引力的控制,提升车辆的稳定性和舒适性等性能。
