The invention discloses a vehicle torque control method, device and equipment and a storage medium, and the method comprises the steps that under the torque zero-crossing working condition, the current torque of a motor is switched into step torque according to the current actual rotating speed of a driving gear and the required torque of the motor; the current relative distance is determined according to the current relative rotating speed of the driving gear relative to the driven gear after torque switching; according to the ratio of the current relative distance to the gear clearance, the current relative rotating speed and the current actual rotating speed, the current torque variable quantity is determined; according to the current torque and the current torque variable quantity, the current target torque of the motor in the process that the driving gear operates to the driven gear is determined. According to the technical scheme, through torque control, the driving gear can pass through the gear clearance and can be rapidly synchronized with the rotating speed of the driven gear, the shaking problem of the torque zero-crossing interval is solved, and meanwhile the dynamic response of the torque zero-crossing interval is guaranteed.

    本申请公开了一种车辆扭矩的控制方法、装置、设备及存储介质,所述方法包括:在扭矩过零的工况下,根据主动齿轮的当前实际转速和电机的需求扭矩,将电机的当前扭矩切换为阶跃扭矩;根据扭矩切换后主动齿轮相对于从动齿轮的当前相对转速,确定当前相对距离;根据当前相对距离与齿轮间隙的比值、当前相对转速和当前实际转速,确定当前扭矩变化量;根据当前扭矩和当前扭矩变化量,确定主动齿轮运行至从动齿轮过程中电机的当前目标扭矩。上述技术方案通过扭矩控制使主动齿轮既能走完齿轮间隙又能快速与从动齿轮的转速同步,在解决扭矩过零区间的抖动问题的同时,保障了扭矩过零区间的动力响应。
