PROBLEM TO BE SOLVED: To provide an on-vehicle device which accurately estimates a traveling direction of a vehicle.SOLUTION: In an on-vehicle device, an outside information processing unit 120 acquires probability tree information representing a running probability of each lane of a road according to a behavior of an own vehicle 2a and acquires vehicle information on the other vehicle 2b in the vicinity of the own vehicle 2a. Based on the probability tree information acquired by the outside information processing unit 120 and the information on the behavior of the own vehicle 2a acquired by an on-vehicle information processing unit 130, a vehicle information generating unit 140 estimates the travel lane of the own vehicle 2a. A warning processing unit 150 estimates a traveling direction of the own vehicle 2a based on the traveling lane of the host vehicle 2a estimated by the vehicle information generating unit 140.SELECTED DRAWING: Figure 4

    【課題】車両の進行方向を正確に推定する車載装置を提供する。【解決手段】車載装置において、車外情報処理部120は、自車両2aの挙動に応じた道路の各車線の走行確率を表す確率木情報を取得すると共に、自車両2aの周辺の他車両2bに関する車両情報を取得する。車両情報生成部140は、車外情報処理部120により取得された確率木情報と、車内情報処理部130により取得された自車両2aの挙動に関する情報とに基づいて、自車両2aの走行車線を推定する。警告処理部150は、車両情報生成部140により推定された自車両2aの走行車線に基づいて自車両2aの進行方向を推定する。【選択図】図4
