The invention provides a hybrid vehicle output torque control method and device, electronic equipment and a vehicle, and relates to the technical field of vehicle torque control. Firstly, the motor target torque and the total target torque of a vehicle in the next period and the SOC value of the current period are obtained, the SOC value is determined as a first input variable, the ratio of the motor target torque to the total target torque is determined as a second input variable, the first input variable and the second input variable are input into a preset fuzzy controller, and an initial torque distribution factor is obtained through output. Then, the initial torque distribution factor is optimized, and a target torque distribution factor is obtained; and finally, according to the target torque distribution factor, the actual output torque of the motor and the actual output torque of the engine of the vehicle in the next period are determined. According to the method, the vehicle is controlled according to the actual output torque of the motor and the actual output torque of the engine, it can be guaranteed that the SOC value of the battery fluctuates within a reasonable range while it is guaranteed that the efficiency of the engine is optimal, the battery is prevented from being overcharged or overdischarged, and therefore the service life of the battery is prolonged.

    本发明提供了一种混动车辆输出转矩控制方法、装置、电子设备及车辆,涉及车辆转矩控制技术领域。首先获取车辆下一周期的电机目标转矩和总目标转矩,以及当前周期的SOC值,并将SOC值确定为第一输入变量,将的电机目标转矩与总目标转矩的比值确定为第二输入变量,输入预设模糊控制器,输出得到初始转矩分配因子。然后,对初始转矩分配因子进行优化,获得目标转矩分配因子。最后,根据目标转矩分配因子,确定车辆下一周期的电机实际输出转矩和发动机实际输出转矩。在本发明中,根据电机实际输出转矩和发动机实际输出转矩对车辆进行控制,能够在确保发动机效率达到最优的同时,保证电池SOC值在合理范围内波动,防止电池过充或过放,从而提高电池的使用寿命。
