The invention provides a vehicle travel mileage area estimation method. The method comprises the following steps of calculating n pieces of theoretical driving end point position information distributed around a vehicle according to the current position information of the vehicle and the endurance limit mileage of the current vehicle, and confirming n driving routes according to the n pieces of theoretical driving end point position information; acquiring the distance and the average driving time of each road section of each driving route, and acquiring a speed-time road spectrum array of each driving route through calculation; according to a vehicle dynamics model, converting the speed-time road spectrum array of each driving route into a power-time road spectrum array; according to the power-time road spectrum array of each driving route, calculating an available residual energy value of the corresponding driving route; according to the power-time road spectrum array and the available residual energy value of each driving route, calculating to obtain position information of a predicted driving end point of each driving route; and drawing a drivable area according to the position information of the predicted driving end points of the n driving routes.

    本发明提供一种车辆行驶里程区域预估方法,根据车辆的当前位置信息以及当前车辆的续航极限里程,计算得到围绕车辆分布的n个理论行驶终点位置信息,并根据n个理论行驶终点位置信息确认n个行驶路线;获取每个行驶路线的每个路段的距离和平均行驶时间,以计算得到每个行驶路线的速度‑时间路谱数组;根据车辆动力学模型,将每个行驶路线的速度‑时间路谱数组分别转换为功率‑时间路谱数组;根据每个行驶路线的功率‑时间路谱数组,计算得到相应行驶路线的可用剩余能量值;根据每个行驶路线的功率‑时间路谱数组和可用剩余能量值,计算得到每个行驶路线的预计行驶终点的位置信息;根据n条行驶路线的预计行驶终点的位置信息,绘制可行驶区域。
