PROBLEM TO BE SOLVED: To provide information on a speed by properly determining a class concerning a speed limit on a road.SOLUTION: When an own vehicle passes a switching area in which a speed type is classified, a determination processing unit 17 determines a speed type, which is adopted after passage, according to class information associated with the switching area. The determination processing unit 17 determines based on a frontage road determination condition concerning a mode of traveling, which is implemented when the own vehicle has passed the switching area, whether a traveling road on which the own vehicle has passed the switching area is a frontage road. If the traveling road is decided not to be the frontage road, a speed monitoring control unit 19 provides a driver with information according to a speed limit associated with the speed type determined at the time of passing the switching area. If the traveling road is determined to be the frontage road, the speed monitoring control unit 19 provides the driver with information according to a speed limit obtained before speed types are switched at the time of passing the switching area.SELECTED DRAWING: Figure 1
【課題】道路における速度制限に関する区分を的確に判断して、速度に関する情報提供を行う。【解決手段】判定処理部17は、速度種別を区分する切替エリアを自車両が通過したときに、当該切替エリアに対応する区分情報に従って通過後の速度種別を判別する。また、判定処理部17は、自車両が切替エリアを通過したときの走行の態様に関する側道判定条件に基づいて、自車両が切替エリアを通過したときの走行路が側道であるか否かを判定する。走行路が側道でないと判定された場合、速度監視制御部19は、切替エリアを通過した際に判別された速度種別に対応する速度制限に従って運転者に対する情報提供を行う。一方、走行路が側道であると判定された場合、速度監視制御部19は、切替エリアを通過した際に速度種別が切替えられる前の速度制限に従って運転者に対する情報提供を行う。【選択図】図1
