PROBLEM TO BE SOLVED: To accurately determine whether a vehicle has changed a lane.SOLUTION: A lane change determination system includes: a vehicle having a measurement device capable of measuring a parameter group including a position, a speed, and a yaw rate; a data center which can make bidirectional communication with the vehicle and has a database in which the position and an azimuth of a road are associated with each other; and a determination part which is disposed in at least one of the vehicle and the data center, and determines whether the vehicle has changed a lane. The determination part estimates a travel azimuth on the basis of the measured parameter group and obtains a road azimuth at the position of the vehicle from the data center. Further, the determination part calculates a relative lateral movement amount on the basis of a relative travel angle formed by the travel azimuth and the road azimuth and a speed of the vehicle. Further, the determination part determines that a lane change has been performed in a case where an integrated value of the relative lateral movement amounts becomes a threshold or greater.SELECTED DRAWING: Figure 2
【課題】 車両が車線変更を行ったか否かを精度良く判定する。【解決手段】 車線変更判定システムは、位置、速度及びヨーレートを含むパラメータ群を測定可能な測定装置を有する車両と、車両と相互通信可能であって位置と道路方位とを対応付けたデータベースを有するデータセンターと、車両及びデータセンターの少なくとも一方に設けられ且つ車両が車線変更を行ったか否かを判定する判定部と、を備える。判定部は、測定したパラメータ群に基づいて進行方位を推定すると共に、データセンターから車両の位置における道路方位を取得する。更に、進行方位と道路方位とがなす相対進行角度と車両の速度とに基づき、相対横移動量を算出する。更に、相対横移動量の積算値が閾値以上となった場合、車線変更を行ったと判定する。【選択図】 図2
