The invention relates to the technical field of automobiles, in particular to an energy recovery control method and device of a hybrid electric vehicle and a vehicle. The method comprises the following steps that whether the hybrid electric vehicle switches a driving mode or not is detected; before it is detected that the driving mode is switched and when the energy recovery condition is met, the hybrid electric vehicle is controlled to enter the energy recovery working condition, and after the driving mode is switched, the actual torque of the clutch and the actual negative net torque of the P2 motor respond to the minimum torque limiting value of the transmission according to the preset gradient; and when the clutch is opened and the idle speed of the P2 motor or the engine meets the preset condition, the hybrid electric vehicle is controlled to quit the energy recovery working condition. According to the method, the problem that when braking or sliding energy is large, the driving mode switching is not smooth can be effectively solved, the smoothness when the energy recovery working condition is quitted is improved, the idling stability of an engine or a motor is improved, and the driving experience is improved.

    本申请涉及汽车技术领域,特别涉及一种混合动力汽车的能量回收控制方法、装置及车辆,其中,方法包括以下步骤:检测混合动力汽车是否切换驾驶模式;在检测到切换驾驶模式前,且满足能量回收条件时,控制混合动力汽车进入能量回收工况,切换驾驶模式后将离合器的实际扭矩和P2电机的实际负净扭矩均以预设梯度响应变速器的最小扭矩限值;在离合器打开且P2电机或者发动机怠速满足预设条件时,控制混合动力汽车退出能量回收工况。本发明实施例的方法可以有效避免制动或者滑行能量较大时驾驶模式切换不平顺的问题,提高退出能量回收工况时的平顺性,并提高发动机或电机怠速的稳定性,提升驾驶体验。
