To provide a technique for more appropriately setting a range in which each vehicle may move, and preventing interference between vehicles on the basis of the range.SOLUTION: A vehicle interference prevention system comprises an approach determination device that determines whether there is a risk of interference between a first vehicle and a second vehicle, and the approach determination device is characterized in that: calculating a distance traveled by the first vehicle and the second vehicle during a first vehicle travel time until a current travel speed of the first vehicle decelerates to a predetermined speed; obtaining an arrival point for each of steering angles of the first vehicle at the time when the first vehicle is calculated and moves a distance; obtaining a first area including the respective arrival points and having a center thereof in front of the traveling direction of the first vehicle; obtaining an arrival point for each steering angle of the second vehicle at the time when the second vehicle moves the calculated distance; obtaining a second area including the respective arrival points and having a center thereof in front of the traveling direction of the second vehicle; and determining whether these areas interfere with each other.SELECTED DRAWING: Figure 4
【課題】各車両がこれから移動する可能性のある範囲をより適切に設定し、これに基づき車両同士の干渉を防止する技術を提供する。【解決手段】車両干渉防止システムは、第1車両と第2車両との干渉のおそれの有無を判定する接近判定装置を有し、接近判定装置は、第1車両の現在の走行速度から所定の速度に減速するまでの第1車両移動時間に、第1車両および第2車両が移動する距離をそれぞれ算出し、第1車両が算出され距離を移動したとするときの到達点を第1車両の操舵角ごとに求め、当該各到達点を含み、中心が第1車両の進行方向の前方となる第1領域を求め、第2車両が算出される距離を移動したとするときの到達点を第2車両の操舵角ごとに求め、当該各到達点を含み、中心が第2車両の進行方向の前方となる第2領域を求め、これら領域が相互で干渉しているかを判定することを特徴とする。【選択図】図4
