To notify a crewman of a vehicle of whether a vehicle is in a reverse running state by appropriately determining the state, so as to prevent issuing of an unnecessary warning.SOLUTION: A warning section of a reverse running determination system issues a reverse running warning #50 to a driver of an object vehicle when a turn behavior of the object vehicle meets a previously regulated regulation condition. Road information in a periphery of the object vehicle includes information of road kinds including discrimination at least between an automobile road and an ordinary road. When the object vehicle approaches from the automobile road to the ordinary road during continuation of a turn behavior, the warning section performs prohibition processing #56 not to issue the reverse running warning after approach to the ordinary road during continuation of the turn behavior.SELECTED DRAWING: Figure 6
【課題】不要な警告を生じさせないように、車両が逆走状態であるか否かを適切に判定して車両の乗員に報知する。【解決手段】逆走判定システムの警告部は、対象車両の旋回挙動が予め規定された規定条件を満たす場合に、対象車両の運転者に逆走警告#50を行う。対象車両の周辺の道路情報は、少なくとも自動車専用道路と一般道路との区別を含む道路種別の情報を含み、警告部は、対象車両が旋回挙動の継続中に、自動車専用道路から一般道路へ進入した場合に、旋回挙動の継続中であって一般道路への進入後は、逆走警告を行わない禁止処理#56を実行する。【選択図】図6
