The invention relates to road travel detection for state of charge management in a motor vehicle. A method for adjusting a state of charge (SOC) limit on a motor vehicle having a propulsion battery pack includes receiving, via a host computer, a pre-drive information set and identifying, from the pre-drive information set, a probability that the motor vehicle is about to begin a road travel. The road travel is a driving event in which the motor vehicle will travel outside a predetermined area. The method further includes expanding the SOC limit of the propulsion battery pack when the motor vehicle is about to begin a road travel such that the total SOC window of the propulsion battery pack is increased for the duration of the road travel. 本发明涉及用于机动车辆中的充电状态管理的道路旅行检测。一种用于调整具有推进电池包的机动车辆上的充电状态(SOC)限制的方法包括经由主计算机接收驾驶前信息集，并且从该驾驶前信息集识别机动车辆即将开始道路旅行的概率。该道路旅行是机动车辆将在预定区域之外行驶的驾驶事件。该方法还包括当机动车辆即将开始道路旅行时扩展推进电池包的SOC限制，使得在道路旅行的持续时间内增大推进电池包的总SOC窗口。
