The invention discloses a torque control method, device and equipment for a driving motor, and the method comprises the steps: monitoring whether a vehicle is changed from a driving state to a first state or not, and the first state represents that the time length of non-flameout parking of the vehicle is greater than a first preset time length; if it is monitored that the vehicle is changed from the running state to the first state, at least controlling the torque of the driving motor to be reduced to a first preset torque within a second preset duration; monitoring whether the vehicle is changed from the first state to a second state or not, wherein the second state represents that the vehicle has a starting demand; if it is monitored that the vehicle is changed from the first state to the second state, the torque of the driving motor is controlled to be increased to a second preset torque within a third preset duration, and the second preset torque is larger than the first preset torque. According to the invention, the technical problem that the control of the vehicle starting smoothness and the temporary parking energy consumption of the vehicle is unbalanced is solved.

    本发明公开了一种驱动电机的扭矩控制方法、装置及设备,该方法包括:监测车辆是否从行驶状态改变至第一状态,第一状态表征车辆未熄火停靠时长大于第一预设时长;若监测到车辆从行驶状态改变至第一状态,至少控制驱动电机的扭矩在第二预设时长内减小至第一预设扭矩;监测车辆是否从第一状态改变至第二状态,第二状态表征车辆有起步需求;若监测到车辆从第一状态改变至第二状态,控制驱动电机的扭矩在第三预设时长内增大至第二预设扭矩,第二预设扭矩大于第一预设扭矩。通过本发明解决了车辆起步平顺性和车辆临时停靠能耗的控制不平衡的技术问题。
