The invention discloses an electric quantity pre-control method for an extended-range vehicle. The electric quantity pre-control method comprises the following steps: S1, determining a target mileage of the vehicle; s2, determining the available mileage of the vehicle; s3, according to the difference value between the target mileage and the available mileage and the speed interval where the vehicle is located, the use state of the range extender is determined, the range extender is used according to the use state of the range extender, and control over the electric quantity of the vehicle is achieved. Consumption of battery electric energy and power generation electric energy of the engine can be distributed more reasonably, low-power power generation of the engine is avoided as much as possible, and oil consumption of the whole vehicle is reduced.

    本发明公开了一种增程式车辆的电量预控方法,包括步骤:S1.确定车辆的目标里程;S2.确定车辆的可用里程;S3.根据目标里程与可用里程之间的差值以及车辆所处的速度区间,来确定增程器的使用状态,并依据增程器的使用状态来使用增程器,实现对车辆电量的控制。本发明能够更加合理地分配电池电能与发动机发电电能的消耗,尽可能地避免了发动机小功率发电,降低了整车的油耗。
