The invention relates to a vehicle slip identification method, a processing device and a vehicle. The slip identification method of the vehicle comprises the steps that the rotating speeds of two driving motors of the vehicle are obtained, the rotating speed with the higher rotating speed is the first rotating speed, the corresponding angular acceleration is the first angular acceleration, the rotating speed with the lower rotating speed is the second rotating speed, and the corresponding angular acceleration is the second angular acceleration; and if the first angular acceleration is greater than 0, judging the slip trend of the driving motor corresponding to the first rotating speed at least according to the first rotating speed, the second rotating speed, the first angular acceleration and the second angular acceleration. The method has the technical effects that the slip trend of the vehicle is quickly recognized through the change of the rotating speed and the torque of the motor, the real-time performance and the accuracy of recognition are improved, the vehicle is intervened and controlled in time based on the recognition result, and the stability and the driving comfort of the vehicle are improved.

    本申请涉及一种车辆的滑转识别方法、处理装置及车辆。该车辆的滑转识别方法包括:获取车辆的两个驱动电机的转速,其中转速较高的为第一转速,对应的角加速度为第一角加速度,转速较低的为第二转速,对应的角加速度为第二角加速度;若所述第一角加速度大于0,则至少依据所述第一转速、第二转速、第一角加速度和第二角加速度判断所述第一转速对应的驱动电机的滑转趋势。本申请的一个技术效果在于,通过电机转速和扭矩的变化快速识别车辆的打滑趋势,提高识别的实时性和准确性,并基于识别结果对车辆及时干预与控制,提高车辆的稳定性和驾驶舒适性。
