The invention provides a gear shifting auxiliary control method of a hybrid vehicle and the hybrid vehicle. The technical problems that energy is wasted due to the fact that the gear shifting time of the hybrid vehicle is long and gear shifting fails when a motor breaks down in the prior art are solved. According to the gear shifting auxiliary control method of the hybrid vehicle and the hybrid vehicle, the rotating speed of the power input shaft of the gearbox is regulated and controlled by regulating and controlling the opening degree and/or the valve closing rate of the exhaust throttle valve, so that the rotating speed of the power input shaft of the gearbox is consistent with the rotating speed of the power output shaft of the gearbox; therefore, the hybrid assembly is assisted in gear shifting to achieve rapid gear shifting, the gear shifting duration in the gear shifting process is shortened, energy waste caused by long gear shifting time of the hybrid gearbox is effectively reduced, and when a motor is adopted for driving, even if the motor breaks down, gear shifting can still be completed.
本申请提供了一种混动车辆的换档辅助控制方法、混动车辆,解决了现有技术中的混动车辆换档时间长导致的能量浪费以及电机发生故障时导致换档失败的技术问题。本申请提供的一种混动车辆的换档辅助控制方法、混动车辆,通过调控排气节流阀的开度和/或关阀速率来调控变速箱的动力输入轴的转速以使得变速箱的动力输入轴的转速与变速箱的动力输出轴的转速一致,从而辅助混动总成换档以实现快速换档,减小换档过程中的换档时长,有效减少混动变速箱换档时间长而导致的能量浪费,且当采用电机作为驱动时,即便电机发生故障,依然可以完成换档。
