The invention provides a range extender control method and device, a range extender controller and a vehicle. According to the method, the current SOC of a power battery of the vehicle and the accelerator opening degree increment of the vehicle in the previous period are obtained in the current period, and if the current SOC of the power battery does not meet the operation condition of a range extender of the vehicle, the range extender is started; if the accelerator opening increment in the previous period is smaller than or equal to a preset opening threshold value, the current generated power upper limit of the range extender is determined on the basis of the actual generated power of the range extender in the previous period, so that the range extender is controlled to work on the basis of the current generated power upper limit in the current period, the upper limit of the current generated power is positively correlated with the actual generated power of the range extender in the last period, so that the situation that the generated power of the range extender is greatly increased under the condition that a driver does not increase the power output intention of the vehicle can be effectively avoided while smooth operation of the vehicle is guaranteed, and the NVH performance of the vehicle is effectively improved.
本申请提供了一种增程器控制方法、装置、增程器控制器及车辆,该方法通过在当前周期获取车辆的动力电池的当前SOC和上一周期内车辆的油门开度增量,若动力电池的当前SOC不满足车辆的增程器的运行条件,且上一周期内油门开度增量小于或等于预定开度阈值,则基于上一周期内增程器的实际发电功率,确定增程器的当前发电功率上限,以在当前周期内,基于该当前发电功率上限控制增程器工作,其中,当前发电功率上限与上一周期内增程器的实际发电功率正相关,由此,通过本方案能够在保证车辆平顺运行的同时,有效避免增程器的发电功率在驾驶员未增加车辆动力输出意图的情况下出现大幅增加,实现了车辆NVH性能的有效提高。
