The invention discloses a vehicle electric quantity maintaining method based on the actual driving working condition of a user, a vehicle adopts a hybrid architecture, and the method comprises the following steps: 1) estimating the mass of the whole vehicle; (2) when the vehicle runs to a ramp, the angle of the current ramp is calculated based on the whole vehicle mass; and 3) re-determining the power generation power of the generator according to the actual working condition of the vehicle on the ramp. The electric quantity maintaining method provided by the invention is suitable for the actual use condition of a user, the condition that the whole vehicle power is insufficient due to limited discharge power of a power battery due to insufficient SOC caused by the fact that the user working condition electric quantity is maintained at a low level is avoided, the user driving experience can be improved, the service life of the battery is prolonged, the energy utilization efficiency is improved, and the vehicle reliability and adaptability are enhanced.

    本发明公开了一种基于用户实际行驶工况的车辆电量维持方法,所述车辆采用混动架构,包括以下步骤:1)整车质量估算;2)当车辆运行至坡道时,基于所述整车质量,计算当前坡道的角度;3)根据车辆在坡道上的实际工况重新确定发电机发电功率。本发明提供的电量维持方法,适用于用户实际使用情况,避免用户工况电量维持在较低水平,导致因SOC不足动力电池放电功率受限出现整车动力不足的情况,可提升用户驾驶体验、延长电池寿命、提高能源利用效率、增强车辆可靠性和适应性。
