The invention relates to a power generation control method and device, a vehicle control unit and a storage medium. The method comprises the steps that when the electric quantity of a current power battery is smaller than or equal to a target electric quantity grade, determining the engine target torque of an engine in a target fuel economy interval, the target electric quantity grade is the maximum electric quantity grade for starting the engine to generate electricity, and calculating the torque required by a driver according to current driving parameters; and according to the driver demand torque and the engine target torque, calculating generator power generation torque and engine power generation torque, and based on the generator power generation torque and the engine power generation torque, controlling the engine to drive the generator to generate power. According to the method of the invention, the engine working in the target fuel economy zone can be controlled to drive the generator to generate electricity, so that the engine charges the current power battery while consuming less fuel, and the overall fuel consumption of the hybrid electric vehicle is reduced.

    本公开涉及一种发电控制方法、装置、整车控制器及存储介质。该方法包括:在当前动力电池的电量小于或等于目标电量等级时,确定发动机处于目标燃油经济区间内的发动机目标扭矩,其中,目标电量等级为启动发动机发电的最大电量等级,根据当前驾驶参数,计算驾驶员需求扭矩,根据驾驶员需求扭矩和发动机目标扭矩,计算发电机发电扭矩和发动机发电扭矩,基于发电机发电扭矩和发动机发电扭矩,控制发动机带动发电机发电。根据本公开实施例,可以控制在目标燃油经济区内工作的发动机带动发电机发电,使得发动机在消耗较少的燃油的同时为当前动力电池充电,降低了混合动力汽车的整体油耗。
