The invention discloses a hybrid electric vehicle, a speed reduction control method, a speed reduction control device and a vehicle-mounted terminal. The speed reduction control method comprises the steps that the actual torque of an engine and driving information of the hybrid electric vehicle are obtained; wherein the driving information comprises vehicle speed information; the vehicle speed information refers to the driving speed of the vehicle when the hybrid electric vehicle enters a sliding working condition; the compensation torque of the motor is determined according to the driving information; determining a motor demand torque of the motor according to the actual torque and the compensation torque; and controlling the motor according to the motor demand torque. The actual torque of the engine and the driving information of the hybrid electric vehicle are obtained, the compensation torque of the motor can be determined through the driving information, and the motor demand torque of the motor is determined according to the actual torque and the compensation torque, so that the motor is controlled based on the motor demand torque; the torque deviation of the engine is counteracted by adjusting the torque of the motor, so that the vehicle decelerates normally.

    本申请公开了一种混合动力汽车及减速控制方法、减速控制装置、车载终端,减速控制方法包括步骤:获取发动机的实际扭矩和混合动力汽车的行驶信息;其中,行驶信息包括:车速信息;车速信息是指混合动力汽车进入滑行工况时汽车的行驶速度;根据行驶信息,确定电机的补偿扭矩;根据实际扭矩和补偿扭矩,确定电机的电机需求扭矩;根据电机需求扭矩对电机进行控制。本申请获取发动机的实际扭矩和混合动力汽车的行驶信息,可以通过行驶信息,确定电机的补偿扭矩,并根据实际扭矩和补偿扭矩,确定电机的电机需求扭矩,从而基于电机需求扭矩对电机进行控制,通过调整电机的扭矩抵消发动机的扭矩偏差,使得车辆正常减速。
