The invention discloses a motor torque zero-crossing control method, device and equipment and a medium, and belongs to the technical field of vehicles. The method comprises the steps that the accelerator pedal state of the automobile is obtained, wherein the accelerator pedal state comprises a treading state and a non-treading state; if the state of the accelerator pedal jumps from the treading state to the non-treading state or jumps from the non-treading state to the treading state, the output torque of the motor is obtained; if the output torque reaches the preset torque threshold value, the output torque is adjusted to be preset tooth leaning torque; if the duration of keeping the output torque as the tooth-leaning torque reaches a preset first duration, adjusting the output torque as a preset buffer torque; if the duration of keeping the output torque as the buffer torque reaches a preset second duration, acquiring the request torque of the motor, and adjusting the output torque as the request torque; wherein the tooth leaning torque is larger than the buffering torque. According to the method, in the motor torque zero-crossing period, the smoothness and the dynamic responsiveness of the automobile can be considered while the gear knocking/pause condition can be reduced.

    本发明公开了一种电机扭矩过零的控制方法、装置、设备及介质,属于车辆技术领域。该方法包括:获取汽车的油门踏板状态,油门踏板状态包括踩下状态和未踩下状态;若油门踏板状态从踩下状态跳变为未踩下状态,或者从未踩下状态跳变为踩下状态,则获取电机的输出扭矩;若输出扭矩达到预设的扭矩阈值,则将输出扭矩调为预设的靠齿扭矩;若输出扭矩保持为靠齿扭矩的时长达到预设的第一时长,则将输出扭矩调为预设的缓冲扭矩;若输出扭矩保持为缓冲扭矩的时长达到预设的第二时长,则获取电机的请求扭矩,并将输出扭矩调为请求扭矩;其中,靠齿扭矩大于缓冲扭矩。该方法在电机扭矩过零期间可以减少敲齿/顿挫情况的同时兼顾汽车的平顺性和动力响应性。
