The invention provides a hybrid vehicle control mode switching coordination control method and a vehicle. The driving torque of an engine for a driving system is calculated through the torque of a generator, and the output torque of a driving motor is continuously adjusted according to the difference value between the driving torque of the engine for the driving system and the torque required by the vehicle, so that the obtained output torque of the driving motor is more accurate; in a control mode switching process, the driving motor is used for dynamic compensation; the error between the sumof the output torque of the driving motor and the driving torque of the engine used for the driving system and the torque required by the vehicle is small, the phenomenon that power transmission is not smooth when a pure electric power mode and a hybrid power mode are switched is avoided, and the drivability and subjective feeling of the vehicle are improved.
本发明提供了一种混合动力车辆控制模式切换协调控制方法及车辆,通过发电机转矩计算发动机用于驱动系统的驱动转矩,根据发动机用于驱动系统的驱动转矩与车辆需求转矩之间的差值不断调整驱动电机的输出转矩,使得到的驱动电机的输出转矩更加精确;在控制模式切换过程中,使用驱动电机进行动态补偿,使驱动电机的输出转矩与发动机用于驱动系统的驱动转矩之和与车辆需求转矩之间的误差较小,避免了纯电动力模式与混合动力模式之间切换时产生动力传递不平顺的现象,提高了车辆的驾驶性能和主观感受。
