Abstract

Abstract Translated from Japanese (57)【要約】 【課題】 リフレクタが高い位置にある先行車も確実に 認識するとともに、看板等の自車線上方に存在する物体 は誤検出しないようにすることで、先行車認識の精度を 向上すること可能な、先行車認識装置を提供すること。 【解決手段】 先行車に接近していると判定され、か つ、先行車が検知されなくなったと判定された場合、第 1の検知エリアよりも上方向の検知エリアを少なくとも 含む第2の検知エリアに切り換えるとともに、第2の検 知エリアにおける最大検知距離を、検知エリア切換手段 による切換え前の先行車までの距離に基づいて設定す る。また、検知エリア切換手段により第2の検知エリア に切り換えた後、第2の検知エリアにおいて先行車が検 知されていないと判定された場合には、第1の検知エリ アにもどるようにする。 (57) [Summary] [PROBLEMS] To accurately recognize a preceding vehicle in which a reflector is at a high position, and to prevent false detection of an object such as a signboard located above the own lane, thereby improving the accuracy of the preceding vehicle recognition. To provide a preceding vehicle recognition device that can be improved. SOLUTION: When it is determined that the preceding vehicle is approaching, and when it is determined that the preceding vehicle is no longer detected, a second detection area including at least a detection area above the first detection area is detected. At the same time, the maximum detection distance in the second detection area is set based on the distance to the preceding vehicle before switching by the detection area switching means. Further, after switching to the second detection area by the detection area switching means, if it is determined that the preceding vehicle has not been detected in the second detection area, the vehicle is returned to the first detection area.
