An operating system for a vehicle having an electric vehicle (EV) driveline and a plurality of electric accessories is described. The controller determines a target off-road path segment via the navigation system and characterizes the target vehicle, environmental conditions, and the target off-road path segment to determine an estimated power consumption for operating the vehicle on the target off-road path segment. The EV driveline and the electric accessories are controlled during operation of the vehicle over the off-road route segment based on the estimated power consumption of the target vehicle. Doing so is to minimize the likelihood of low SOC events for the DC power supply of the path segment and avoid low battery states at locations remote from the charging station.

    描述了一种用于具有电动车辆(EV)传动系和多个电动附件的车辆的操作系统。控制器经由导航系统确定目标越野路径路段,并且表征目标车辆、环境条件以及目标越野路径路段,以确定用于使车辆在目标越野路径路段上操作的估计的电能消耗。基于估计的目标车辆的电能消耗,在车辆在越野路径路段的操作期间控制EV传动系和电动附件。这样做是为了最小化针对所述路径路段的DC电源的低SOC事件的可能性,并避免在远离充电站的位置处的低电池状态。
