The invention provides a vehicle torque zero-crossing control method and device, electronic equipment and a vehicle. The method comprises the following steps: acquiring torque data and vehicle speed data of a vehicle to obtain real-time torque data and vehicle speed data; according to the torque data and the vehicle speed data, a preset triggering condition of a torque zero-crossing interval of the vehicle is judged; when the vehicle meets the triggering condition corresponding to the torque zero-crossing interval, executing query operation on a corresponding torque table according to the torque change trend of the vehicle; and determining a final motor request torque corresponding to the torque zero-crossing interval according to a query result, and performing smooth torque zero-crossing control on a driving motor of the vehicle by using the final motor request torque. According to the invention, the application scene of torque zero-crossing control is improved, dynamic and smooth torque zero-crossing control of the driving motor is realized, and the driving experience of a driver is improved.

    本申请提供了一种车辆扭矩过零控制方法、装置、电子设备及车辆。该方法包括:对车辆的扭矩数据以及车速数据进行采集,以获取实时的扭矩数据和车速数据;依据扭矩数据和车速数据,对预设的车辆的扭矩过零区间的触发条件进行判断;当车辆满足扭矩过零区间对应的触发条件时,依据车辆的扭矩变化趋势对相应的扭矩表执行查询操作;依据查询结果确定与扭矩过零区间相对应的最终电机请求扭矩,利用最终电机请求扭矩对车辆的驱动电机进行平滑的扭矩过零控制。本申请提升扭矩过零控制的使用场景,实现动态、平滑的驱动电机扭矩过零控制,改善驾驶员的驾驶体验。
