The invention discloses an intelligent start-stop control method for a hybrid electric vehicle, which comprises the following steps that the hybrid electric vehicle is driven by pure electricity to start and then normally runs, and when the rotating speed of a motor driving shaft reaches an economic efficiency interval of the rotating speed of an engine, the motor driving shaft and an engine driving shaft are linked by controlling a clutch to work; inertial kinetic energy of the automobile is used for starting a flywheel of the engine, and engine starting is achieved. The method has the advantages of prolonging the service life of the starting motor, reducing energy consumption and the like.

    本发明公开了一种混合动力汽车智能启停控制方法,包括如下步骤:通过纯电驱动混合动力汽车起步之后正常行驶,当电机驱动轴转速达到发动机转速经济效率区间时,通过控制离合器工作,将电机驱动轴和发动机驱动轴联动;利用汽车的惯性动能来启动发动机的飞轮,实现发动机启动。本发明具有延长启动马达使用寿命、降低能耗等优点。
