The invention relates to a range extender start-stop control method and device based on navigation, an automobile and a computer readable storage medium, and the method comprises the steps: obtaining the current navigation distance and the current traffic congestion degree of a user, and the average discharge power of a battery in a historical preset time period of the user in a whole automobile power-on state; according to the current traffic congestion degree, the battery average discharge power and the correction coefficient of the battery average discharge power, calculating estimated battery discharge power and estimated battery remaining capacity after the vehicle runs; determining whether the average discharge power of the battery is greater than the corresponding maximum discharge power of the battery and whether the current residual electric quantity of the battery is less than a preset charge threshold; if so, acquiring the lowest residual electric quantity of the battery; and calculating the required charging power of the range extender in the preset starting time, and controlling the range extender to start. According to the scheme, the energy consumption loss caused by frequent starting of the range extender can be effectively reduced, and meanwhile the dynamic property of the vehicle is improved in the running process of the vehicle.

    本申请涉及一种基于导航的增程器启停控制方法、装置、汽车及计算机可读存储介质,该方法包括:在整车上电的状态下,获取用户当前导航距离和当前交通拥堵程度,以及用户历史预设时间段内的电池平均放电功率;根据当前交通拥堵程度、电池平均放电功率、电池平均放电功率的修正系数计算预估电池放电功率及车辆行驶后的预估电池剩余电量;确定电池平均放电功率是否大于对应的电池最大放电功率,以及当前电池剩余电量是否小于预设充电阈值;若均是,则获取电池最低剩余电量;计算增程器在预设启动时间内的需求充电功率,控制增程器启动。通过本方案,能够有效降低增程器频繁启动导致的能耗损失,同时使得车辆在行驶过程中,提升车辆的动力性。
