To provide a technology for reducing a possibility that a target trajectory becomes erroneous.SOLUTION: A target trajectory acquisition system comprises: a road face shape acquisition part for acquiring a road shape of a road on which a vehicle travels on the basis of a traveling-scheduled route of the vehicle; and a target trajectory acquisition part for acquiring a target trajectory of the vehicle on the basis of a compartment line on the road which is specified according to the road shape. When a curvature radius as the road shape is equal to a threshold or smaller, the target trajectory acquisition part acquires a line passing a center of the compartment lines existing at the left and right as a target trajectory when the compartment lines existing at the left and right of the road can be recognized, and when the compartment line can be recognized at only a single side of the left and right of the road, the target trajectory acquisition part acquires a line passing a position apart from the recognized compartment line by a constant distance as the target trajectory.SELECTED DRAWING: Figure 1
【課題】目標軌道が誤りになる可能性を低減する技術の提供。【解決手段】車両の走行予定経路に基づいて車両が走行する道路の道路形状を取得する道路形状取得部と、道路形状に応じて特定される道路上の区画線に基づいて車両の目標軌道を取得する目標軌道取得部と、を備え、目標軌道取得部は、道路形状としての曲率が閾値以下である場合、車両の左右に存在する区間線が認識できた場合には、左右に存在する区画線の中央を通る線を目標軌道として取得し、車両の左右の片側のみにおいて区間線が認識できた場合には、認識できた区画線から一定距離の位置を通る線を目標軌道として取得する、目標軌道取得システムを構成する。【選択図】図１
