PROBLEM TO BE SOLVED: To provide a confluence support device that provides a vehicle supporting confluence with information with little arithmetic load when calculating the contents of confluence support.SOLUTION: A confluence support device receives the position and speed information on a vehicle at a confluence from sensors 2 and 3 that are installed at a position where they can detect a vehicle at the confluence and can detect the position and speed on a vehicle at the confluence. The confluence support device comprises: a distance calculation unit 11 that calculates distance between the vehicle at the confluence and a confluent point from a detection result of the sensors and road data on the confluence stored in a storage unit 13 in advance; a simple map creation unit 12 that creates a simple map arranging the vehicle at the confluence together with the speed information detected by the sensors on a straight-line flat road map including a virtual confluent point on the basis of the distance to the confluent point calculated by the distance calculation unit; and a road-to-vehicle communication unit 4 that transmits the simple map to the vehicle on a confluent path.SELECTED DRAWING: Figure 1
【課題】合流支援を行う車両に、合流支援の内容を算出する際の演算負荷が少ない情報を提供する合流支援装置を提供する。【解決手段】合流部の車両を検知できる位置に設置され、合流部の車両の位置及び速度を検知するセンサ2、3から、合流部の車両の位置及び速度情報を受信する合流支援装置である。センサの検知結果及び記憶部13に予め記憶してある合流部の道路データから、合流部の車両と合流地点までの距離を算出する距離算出部11と、距離算出部の算出した合流地点までの距離に基づき、合流部の車両を仮想の合流地点を有する直線平坦路マップ上に、センサが検知した速度情報と共に配置した簡易マップを作成する簡易マップ作成部12と、前記簡易マップを、合流路上の車両に送信する路車間通信部4と、を備える。【選択図】図1
