The invention provides a vehicle-mounted battery discharge control method and a vehicle control system.The vehicle-mounted battery discharge control method comprises the steps that under the condition that discharge requirements exist, the remaining endurance mileage of current fuel oil is detected, and the protection mileage set by a user is obtained; adjusting the cut-off residual electric quantity of the battery pack according to the protection mileage and the residual endurance mileage; and controlling the battery pack to discharge according to the cut-off residual electric quantity. Under the condition that the discharge demand exists, the cut-off residual electric quantity of the battery pack is adjusted according to the protection mileage and the residual endurance mileage, and then the battery pack is controlled to discharge according to the cut-off residual electric quantity, so that the dynamic adjustment of the residual cut-off electric quantity of the battery pack in the discharge process is realized; the harm of noise, waste gas and the like caused by repeated starting and stopping of the engine due to fixed cut-off residual electric quantity can be effectively avoided.

    本发明中提供了一种车载电池放电控制方法及车辆控制系统,该车载电池放电控制方法包括:在存在放电需求的情况下,检测当前燃油的剩余续航里程,并获取用户设定的保护里程;根据所述保护里程和所述剩余续航里程调整电池包的截止剩余电量;根据所述截止剩余电量控制所述电池包进行放电。本发明在存在放电需求的情况下,根据保护里程和剩余续航里程调整电池包的截止剩余电量,然后根据所述截止剩余电量控制所述电池包进行放电,实现放电过程中电池包的剩余截止电量的动态调节,可以有效的避免固定截止剩余电量引起的发动机反复启动关闭,带来噪声,废气等危害。
