The invention provides a parking regeneration control method and device and a hybrid electric vehicle, and the method comprises the steps that when the hybrid electric vehicle needs to enter a parking regeneration state, a particle catcher regeneration unit sends a parking regeneration control instruction to a vehicle control unit; after the vehicle control unit receives the regeneration control instruction, whether parking regeneration is allowed or not is judged according to the current vehicle state condition; if so, determining a regeneration strategy according to the current available charging power of the battery and the temperature value of the particle catcher; and the whole vehicle control unit controls the torque and the rotating speed of the engine according to the regeneration strategy. According to the technical scheme provided by the embodiment of the invention, the parking regeneration of the hybrid vehicle is ensured, the safety is also ensured, and better regeneration speed and fuel economy are provided.
本发明提供一种驻车再生控制方法、装置及混合动力汽车,其中方法包括:当需要进入驻车再生状态时,颗粒捕捉器再生单元向整车控制单元发送驻车再生控制指令;整车控制单元接收所述再生控制指令后,根据当前车辆状态条件判断是否允许进入驻车再生;若允许,根据当前电池可用充电功率以及所述颗粒捕捉器的温度值确定再生策略;整车控制单元根据所述再生策略控制发动机的扭矩和转速。本发明实施例提供的技术方案保证了混合动力车辆驻车再生的同时,也保证了安全性,并提供较好的再生速度和燃油经济性。
