The invention discloses a torque control method and device, equipment and a storage medium, which are used for improving the user experience during torque zero passage. The vehicle is monitored, if it is determined that the torque zero-crossing process is triggered under the working condition that the vehicle steps on the accelerator after sliding, the vehicle speed, the acceleration, the accelerator pedal opening degree and other related parameter information are obtained, and torque control related parameters are obtained by reading values calibrated in advance in a storage; by judging the size of the original required torque and the size of the filtering required torque, it is judged that torque reduction control is started, and the torque rising zero-crossing fitting process is further completed; judging whether repeated zero-crossing knocking treatment near zero torque needs to be carried out or not by judging the magnitude of the filtering required torque after zero crossing; and the process of controlling the torque to coincide with the filtering demand torque is completed by acquiring the time parameter of the transition area. Through the series of torque control processes, the effects of rapid zero crossing and abnormal knocking sound suppression are achieved.
本申请公开了一种扭矩控制方法、装置、设备和存储介质,用于提高扭矩过零时的用户体验。本申请对车辆进行监测,若在车辆滑行后踩油门工况,确定触发了扭矩过零过程,则获取车速、加速度、油门踏板开合度等相关参数信息,并通过读取存储器中预先标定的值获取扭矩控制相关参数;通过判断原始需求扭矩及滤波需求扭矩的大小,判断进入降扭控制并进一步完成升扭过零贴合过程;通过判断过零后滤波需求扭矩的大小,判断是否需要进行零扭矩附近的防反复过零敲击处理;通过获取过渡区时间参数,完成控制扭矩向滤波需求扭矩重合的过程。通过这一系列的扭矩控制过程,达到快速过零并抑制敲击异响的效果。
