在行驶辅助系统(500)中,位置信息取得部(110)取得车辆(200)的位置信息(111)。路线生成部(120)根据路径引导中使用的简易地图(181)和位置信息(111),在简易地图(181)中生成行驶路线。周边地图生成部(130)使用位置信息(111),在车辆(200)的行驶中生成周边地图(182)。特征提取部(140)提取简易地图(181)和周边地图(182)各自的道路的特征。位置对准部(150)根据道路的特征进行简易地图(181)与周边地图(182)的位置对准,计算车辆位置(151)。然后,线路生成部(170)使用车辆位置(151)将行驶路线投影到周边地图(182)上,生成用于供车辆(200)行驶的线路(171)。

    In a travel assist system (500), a positional information acquisition unit (110) acquires positional information (111) of a vehicle (200). A route generation unit (120) generates a travel route on a simple map (181), based on positional information (111) and the simple map (181) which is used for course guidance. A surrounding area map generation unit (130) generates a surrounding area map (182) of the vehicle during travel of the vehicle (200), using the positional information (111). A characteristic extraction unit (140) extracts a road characteristic on each of the simple map (181) and the surrounding area map (182). An alignment unit (150) aligns the simple map (181) and the surrounding area map (182) with each other based on the road characteristic, and calculates a vehicle position (151). Then, a path generation unit (170) projects a travel route onto the surrounding area map (182) using the vehicle position (151), and generates a path (171) for the vehicle (200) to take for traveling.
