The invention belongs to the technical field of engines, and provides an engine energy-saving control method and system for a hybrid electric vehicle. When the hybrid electric vehicle is in a pure electric mode and the state of an engine meets a preset condition, power supply of related actuators of a throttling valve and an exhaust gas recirculation valve is cut off; the problem of energy waste caused by the fact that the throttle valve and the exhaust gas recirculation valve are always in an actuator motor control state in a pure electric mode is solved, the working time of the storage battery is prolonged, the service life of the storage battery is prolonged, and the problems of storage battery feed and the like are avoided.

    本发明属于发动机技术领域,提供了一种混合动力汽车的发动机节能控制方法及系统,本发明中混合动力汽车处在纯电模式下,当发动机状态满足预设条件时,切断节流阀和废气再循环阀相关执行器的供电,解决了纯电模式下节流阀和废气再循环阀一直处于执行器电机控制状态,造成能量浪费的问题,提高了电瓶工作时长和寿命,避免了电瓶馈电等问题。
