The invention discloses a starting control strategy of a range extender, which comprises an engine and a generator. The starting control strategy comprise the steps that S10 the position of the generator is positioned; S20 a controller controls a rotor of the generator to reversely rotate by a mechanical angle of 60 degrees; S30 the controller controls forward acceleration starting of the generator; and S40 the engine is driven by the generator to be ignited and started, and the generator is converted into a power generation mode after successful starting. By the adoption of the control strategy, the starting success rate can be increased, and the failure rate of the controller is reduced. 本发明公开一种增程器的启动控制策略，包括发动机和发电机，其特征在于，按以下步骤启动：S10：对发电机的位置进行定位；S20：控制器控制发电机的转子反向旋转60°机械角；S30：控制器控制发电机正向加速启动；S40：发动机在发电机的带动下点火启动，启动成功后发电机转为发电模式。采用本发明的控制策略，能够提高启动成功率，降低控制器故障率。
