The invention relates to the technical field of vehicles, and particularly discloses a torque control method and device of a hybrid vehicle, the vehicle and a storage medium. According to the torque control method of the hybrid vehicle, the required rotating speed of an engine is obtained, and the engine runs at the required rotating speed and is in transmission connection with a gearbox; the optimal power of the engine is determined based on the required rotating speed of the engine, the optimal torque of the engine is determined based on the optimal power, the required rotating speed of the engine and the first mapping relation, when the charging interface is connected with the charging gun, the current torque of the engine is obtained, and when the current torque is larger than the optimal torque, the engine is charged. The first assisting torque output by the motor is determined based on the difference value N1 of the current torque and the optimal torque and the SOC of the battery, the motor outputs the first assisting torque, the current torque of the engine is made to be close to or equal to the optimal torque under the condition that the SOC of the battery is fully considered, and then the fuel economy and the NVH performance of the engine are guaranteed; and the working efficiency of the whole vehicle is improved.
本发明涉及车辆技术领域,具体公开了一种混动车辆的扭矩控制方法、装置、车辆及存储介质,该混动车辆的扭矩控制方法通过获取发动机的需求转速并使发动机以需求转速运行且与变速箱传动连接,基于发动机的需求转速确定发动机的最优功率,基于最优功率、发动机的需求转速和第一映射关系确定发动机的最优扭矩,当充电接口与充电枪连接时,获取发动机的当前扭矩,并当当前扭矩大于最优扭矩时,基于当前扭矩与最优扭矩的差值△N1以及电池的SOC确定电机输出的第一助力扭矩并使得电机输出第一助力扭矩,在充分考虑了电池的SOC情况下,使得发动机的当前扭矩靠近或等于最优扭矩,进而保证发动机的燃油经济性和NVH性能,并提升整车工作效率。
