The invention discloses a range extender control method which comprises the following steps that S1, a range extender receives a starting signal and judges and sends a target torque signal to a GCU according to the maximum allowable discharge power Pdischargemax of a current battery pack and the water temperature Tcoolant of an engine, and the GCU controls a generator to send positive torque to drag the engine to operate; s2, when the engine runs to the target rotating speed, the GCU generates zero torque and quits starting, and the ECU conducts oil injection ignition; and S3, according to the maximum allowable charging power Pchargemax, a target torque is set for the ECU, and a target rotating speed is set for the GCU. And S4, after a set time, after the front oxygen sensor closed-loop state Soxygen reports that the closed loop is completed, completing ignition. And S5, after light-off is completed, entering a first power generation mode.
本发明公开了一种增程器控制方法，包括以下步骤：S1，增程器接收启动信号，并根据当前电池包的最大允许放电功率Pdischargemax与发动机水温Tcoolant判断发出目标扭矩信号至GCU，GCU控制发电机发出正扭矩拖动发动机运转；S2，当发动机运转至目标转速时，GCU发0扭矩退出启动，ECU进行喷油点火；S3，根据最大允许充电功率Pchargemax，对ECU设定目标转矩，对GCU设定目标转速。S4，经过设定时间后，同时前氧传感器闭环状态Soxygen报出闭环完成后，完成起燃。S5，起燃完成后，进入第一发电模式。
