The invention discloses a gasoline engine generator control and torque compensation method which comprises the following steps: generator power generation opportunity control: when an engine is in a vehicle acceleration, starting or full load working condition, the generator is controlled not to generate power; when the engine is not in the working condition, the generator is controlled to recover normal power supply; power generation load calculation of a power generator: firstly, performing primary correction on an LIN communication output result; and then carrying out secondary correction on the primary correction result output by the LIN communication to obtain the final power generation load of the generator. The method comprises the following steps: firstly, obtaining a torque compensation basic value of an alternating-current generator; water temperature correction is conducted on torque compensation of the alternating-current generator; and then, starting time correction is carried out on the torque compensation value of the alternating-current generator after water temperature correction, and the final torque compensation value of the engine to the alternating-current generator is obtained.

    本发明公开了一种汽油机发电机控制及扭矩补偿方法,包括:发电机发电时机控制:当发动机处于车辆加速、起步或满载工况时,控制发电机不进行发电;当发动机并非处于上述工况时,控制发电机恢复正常供电;发电机的发电负荷计算:首先对LIN通信输出结果进行一次修正;然后对上述LIN通信输出的一次修正结果进行二次修正,得到最终的发电机的发电负荷;发动机对发电机扭矩补偿计算:首先,获得交流发电机扭矩补偿基本值;对交流发电机扭矩补偿进行水温修正;然后,对水温修正后的交流发电机扭矩补偿值进行起动时间修正值,得到最终的发动机对交流发电机的扭矩补偿值。
