- 車両の周囲にレーザ光を照射し、前記車両の周囲に存在する物体で反射された光を受光する複数のレーザレーダと、
前記複数のレーザレーダを制御すると共に、前記複数のレーザレーダの受光結果に基づいて前記物体を認識する制御装置とを備えた車載レーダシステムにおいて、
前記制御装置は、
前記物体の認識結果に基づき、前記複数のレーザレーダのうちのいずれかのレーザ光が前記物体で遮られて不検知領域が生じているかどうかを判定し、
前記複数のレーザレーダのうちの一のレーザレーダに対して不検知領域が生じていない場合、前記一のレーザレーダに隣り合う他のレーザレーダの検知範囲を初期設定値とし、前記検知範囲の初期設定値に基づいて前記他のレーザレーダを駆動させ、
前記複数のレーザレーダのうちの一のレーザレーダのレーザ光が前記物体で遮られて不検知領域が生じている場合、前記不検知領域の少なくとも一部が検知可能となるように、前記一のレーザレーダに隣り合う他のレーザレーダの検知範囲を前記初期設定値より拡大し、前記拡大された検知範囲に基づいて前記他のレーザレーダを駆動させることを特徴とする車載レーダシステム。 - 請求項1に記載の車載レーダシステムにおいて、
前記制御装置は、
前記複数のレーザレーダの受光結果に基づき、前記複数のレーザレーダのうちのいずれかに障害が発生しているかどうかを判定し、
前記複数のレーザレーダのうちの一のレーザレーダに障害が発生している場合、前記一のレーザレーダの検知範囲を補うように、前記一のレーザレーダに隣り合う他のレーザレーダの検知範囲を拡大させることを特徴とする車載レーダシステム。
