The invention provides a power generation control method and system of an extended-range vehicle and a vehicle control unit, and relates to the technical field of vehicles. The method comprises the steps that the SOC of a battery of the extended-range vehicle is obtained; when the SOC is larger than a first preset SOC value and smaller than a second preset SOC value, target generated power of the extended-range vehicle is calculated according to the SOC based on a preset generated power correction strategy; wherein when the target generated power is calculated based on the preset generated power correction strategy, if the SOC is greater than a third preset SOC value and less than a fourth preset SOC value, the SOC is in negative correlation with the target generated power; and controlling the extended-range vehicle to generate power according to the target generated power. When the electric quantity of the battery is low, the electric quantity can be guaranteed, and meanwhile, the NVH performance of the vehicle is considered.
本发明提供一种增程式车辆的发电控制方法、系统及整车控制器,涉及车辆技术领域,本方法包括:获取增程式车辆的电池的SOC;在SOC大于第一预设SOC值,且小于第二预设SOC值时,基于预设发电功率修正策略,根据SOC,计算增程式车辆的目标发电功率;其中,在基于预设发电功率修正策略计算目标发电功率时,若SOC大于第三预设SOC值,且小于第四预设SOC值,则SOC与目标发电功率呈负相关;控制增程式车辆按照目标发电功率进行发电。本发明能够在电池电量较低时,实现电量保电,同时兼顾车辆的NVH性能。
