PROBLEM TO BE SOLVED: To provide a sensor abnormality detection apparatus capable of highly accurately detecting abnormality of a sensor possibly occurring at detection of collision in a vehicle incorporated with plural surrounding environment recognition sensors.SOLUTION: A sensor abnormality detection apparatus includes: a first sensor for detecting a condition of a first zone surrounding a vehicle itself; a second sensor for detecting a condition of a second zone that is different from the first zone and has an overlap zone overlapping with a part of the first zone; sensor abnormality determination means for determining abnormality of the first and second sensors; and collision detection means for detecting an event of the vehicle itself colliding with an object. If the first zone does not overlap with the second zone in the overlap zone after a collision is detected, the sensor abnormality determination means determines that abnormality has occurred to at least one of the first and second sensors.
【課題】複数の周辺環境認識センサを搭載した車両において、衝突検出時に生じ得るセンサの異常を高精度に検出できるセンサ異常検出装置を提供することを課題とする。【解決手段】センサ異常検出装置は、自車両周辺の第1領域の状況を検出する第1のセンサと、第1領域とは異なる領域であって当該第1領域の一部と重複する重複領域を有する第2領域の状況を検出する第2のセンサと、第1のセンサ及び第2のセンサの異常を判定するセンサ異常判定手段と、自車両が物体に衝突したことを検出する衝突検出手段と、を備え、センサ異常判定手段は、衝突を検出した後、重複領域において第1領域と第2領域とが重複しない状況であると、第1のセンサ及び第2のセンサのうち少なくともいずれか一方に異常があると判定する。【選択図】図1
