Abstract: A method of determining a coasting area is disclosed, together with methods of providing coasting information to a vehicle driver; coasting being when the vehicle is allowed to decelerate or to roll without being under power. In embodiments, the coasting area is determined by: determining an end point location of a coasting area based upon a location in map data of an expected decrease in speed of a vehicle traversing a road network represented by the map data; determining a start point location of the coasting area based on at least one attribute associated with the map data proximal to the end point location; and generating coasting information indicative of the coasting area having the start point and end point locations. In other embodiments, coasting information is provided to a driver by: determining a location of a coasting area based on a location of a navigation device; and determining whether to output information indicative of the coasting area based on a current speed of travel of the navigation device and, if so, outputting an indication of the coasting area.

Abstract translation: 公开了一种确定惯性区域的方法，以及向车辆驾驶员提供滑行信息的方法; 当车辆被允许减速或滚动而不受电时，惯性滑行。 在实施例中，滑行区域通过以下方式确定：基于由地图数据表示的穿过道路网络的车辆的预期速度下降的地图数据中的位置来确定惯性区域的终点位置; 基于与靠近终点位置的地图数据相关联的至少一个属性来确定惯性区域的起点位置; 以及生成表示具有起点和终点位置的惯性区域的滑行信息。 在其他实施例中，通过以下方式向驾驶员提供滑行信息：基于导航装置的位置来确定惯性区域的位置; 以及基于所述导航装置的当前行驶速度来确定是否输出指示所述惯性行驶区域的信息，如果是，则输出所述惯性区域的指示。
