The invention discloses a power generation control method and system for an extended-range vehicle, and relates to the technical field of extended-range vehicles, and the method comprises the steps: obtaining the required power generation power according to a vehicle control unit, and obtaining the current actual power generation power of a power generator according to a power generator controller; judging whether the absolute value of the difference between the required power generation power and the actual power generation power is greater than a preset power generation power calibration quantity; wherein if the absolute value of the difference value between the required power generation power and the actual power generation power is larger than the preset power generation power calibration value, the power generator controller controls the rotating speed of the power generator through rotating speed control; and if the absolute value of the difference value between the required power generation power and the actual power generation power is smaller than the preset power generation power calibration value, a power generator controller controls the rotating speed of the power generator through torque control. Through rotating speed control or torque control, optimal control over the generator system is achieved, and the generated power of the generator system can be effectively improved.

    本发明公开了一种增程式车辆发电控制方法及系统,涉及增程式车辆技术领域,该方法包括:根据整车控制器获取需求发电功率,并根据发电机控制器获取发电机当前的实际发电功率;判断需求发电功率与实际发电功率的差值绝对值是否大于预设的发电功率标定量;其中,若需求发电功率与实际发电功率的差值绝对值大于预设的发电功率标定量,则使发电机控制器通过转速控制实现发电机的转速控制;若需求发电功率与实际发电功率的差值绝对值小于预设的发电功率标定量,则使发电机控制器通过扭矩控制实现发电机的转速控制。则本发明通过转速控制或扭矩控制,实现了对发电机系统的最优控制,能够有效提升发电机系统的发电功率。
