The invention provides a torque control method, system and device, a medium and a vehicle, and the method comprises the steps: when a belt of a motor slips, according to the belt transmission torque of the motor when the belt slips and the absolute rotating speed difference between the motor and a vehicle engine, calculating the limiting torque of the motor when the belt slips; and then torque control is carried out on the motor according to the calculated limiting torque until belt slipping of the motor is eliminated. According to the invention, by eliminating the belt slipping of the motor, the negative influence caused by the belt slipping of some new energy vehicle types at present can be overcome, and meanwhile, the good drivability and the qualified emission standard of the vehicle are ensured. After belt slipping is eliminated, the motor limiting torque can be gradually recovered until the motor limiting torque reaches the set target torque. After the motor torque recovery times reach the preset upper limit times, the limited torque of the motor is not recovered any more, so that interference of external factors such as noise on a driver is relieved.

    本申请提供一种扭矩控制方法、系统、设备及介质、一种车辆,该方法包括:在电机出现皮带打滑时,根据电机出现皮带打滑时的皮带传动扭矩、电机与车辆发动机的绝对转速差,计算出电机在皮带打滑时的限制扭矩,然后根据计算出的限制扭矩对电机进行扭矩控制,直至电机的皮带打滑消除。本申请通过消除电机的皮带打滑,可以克服目前部分新能源车型在皮带打滑时所带来的负面影响,同时保证了车辆具有良好的驾驶性以及合格的排放标准。本申请在皮带打滑消除后,还可以逐步恢复电机限制扭矩,直至电机限制扭矩达到设定的目标扭矩。本申请在电机扭矩恢复次数达到预设上限次数后,就不再对电机限制扭矩进行恢复,以减轻噪音等外界因素对驾驶员的干扰。
