Abstract: A driving control method for a hybrid vehicle has state of charge (SOC) ranges including a high SOC range, an intermediate SOC range and a low SOC range, and a plurality of power distribution strategies corresponding to the respective SOC ranges. The driving control method controls the hybrid vehicle using a power distribution strategy corresponding to an SOC range to which a current SOC of the hybrid vehicle belongs. When a speed of the hybrid vehicle is high or low and is outside a predetermined range, boundary values of the intermediate SOC range and the low SOC range among the SOC ranges are increased.
Abstract translation: 混合动力车辆的驱动控制方法具有包括高SOC范围，中间SOC范围和低SOC范围的充电状态（SOC）范围，以及与各SOC范围对应的多个配电策略。 驱动控制方法使用与混合动力汽车的当前SOC所属的SOC范围对应的配电策略来控制混合动力车辆。 当混合动力车辆的速度高或低并且在预定范围之外时，SOC范围中的中间SOC范围和低SOC范围的边界值增加。
