The invention discloses an automobile range extender control method, a range extender control module and a range-extended automobile, which can reduce the starting and stopping times of a range extender and improve the power response speed of the automobile. According to the control method for the automobile range extender, when the automobile recovers energy, the range extender can be controlled to cut off oil and idle, the energy recovery efficiency can be improved, the use strength of a mechanical friction type brake pad is reduced, and therefore the service life of the mechanical friction type brake pad is prolonged; oil injection of the engine is forbidden, positive torque is applied to the generator through the range extender to maintain the rotating speed of the engine, and when the generator needs to generate electricity again, direct oil injection is performed to quickly finish ignition, so that the restarting time of the range extender is shortened, the response speed of the range extender to the driving demand power is increased, and the power response speed of the vehicle is increased; the fuel cut idling of the range extender can reduce the starting and stopping times of the range extender, the rotating speed of the engine is not obviously changed in the whole energy recovery process, vibration which can be perceived by a user and is caused by starting and stopping of the range extender is reduced, and the driving experience is good.
本发明公开了一种可以减少增程器的启停次数、提高车辆动力响应速度的汽车增程器控制方法、增程器控制模块及增程式汽车。本发明的汽车增程器控制方法,在车辆进行能量回收时,可以控制增程器断油怠速,可以提高了能量回收效率,降低了机械摩擦式刹车片使用强度,从而提高其寿命;通过禁止发动机喷油,通过增程器发电机施加正扭矩维持发动机转速,当需要发电机再次发电时,直接喷油快速完成点火,缩短了增程器重新启动的时长,提高了增程器对驾驶需求功率的响应速度,从而提高车辆动力响应速度;增程器断油怠速可以减少增程器的启停次数,整个能量回收过程发动机转速没有明显变化,减少用户可感知的因增程器启停导致的震动,驾驶体验好。
