The invention relates to the technical field of vehicles, and discloses a motor torque zero-crossing control method and device, a vehicle, electronic equipment and a medium. According to the method, when the vehicle is in a continuous high-speed sliding state, a motor is controlled to sequentially output first-direction torque and second-direction torque, so that a gear moves close to teeth on different sides; the motor rotor angular speed and the vehicle tire rotation angular speed in the process are collected, a transmission system gap is determined, a target torque gradient correction value is obtained through matching, then the current torque zero-crossing gradient of the vehicle is determined, torque zero-crossing control is conducted on the motor of the vehicle, and the torque zero-crossing control over the motor of the vehicle is achieved by correcting the current torque zero-crossing gradient in the vehicle running process. And the current torque zero-crossing gradient of each vehicle is determined and corrected individually, so that the suitability of the current torque zero-crossing gradient is improved, the smoothness of the output torque of the power system is improved, and the user experience is improved.

    本发明涉及车辆技术领域,公开了一种电机扭矩过零控制方法、装置、车辆、电子设备及介质,该方法通过在车辆处于持续高速滑行状态下,控制电机依次输出第一方向扭矩和第二方向扭矩,使得齿轮在不同侧靠齿运动,采集这一过程中的电机转子角速度和车辆轮胎转动角速度,确定传动系统间隙,并匹配得到目标扭矩梯度修正值,进而确定车辆的当前扭矩过零梯度,以对车辆的电机进行扭矩过零控制,通过在车辆行驶过程中当前扭矩过零梯度进行修正,以及对每一辆车个性化地进行当前扭矩过零梯度的确定与修正,提升了当前扭矩过零梯度的适配性,提升了动力系统输出扭矩的平顺性,提升了用户体验度。
