To provide a car shape detection device and a car wash machine equipped with the same, that can create car shape data that eliminates as much influence of splashed water as noise in car shape detection, even when a car wash course is performed in which car body detection operation and car wash operation are executed in parallel.SOLUTION: During a traveling and moving action of a car wash machine main body 1, a car is scanned at a plurality of times for detecting a car body at the same position of the car body; car body data obtained for a number of car scans is temporarily stored in a car body scan storage unit 22; the majority decision about the determination result of each optical axis B related to the stored car body data is performed and the determination result with the larger number is determined as the determination result of the optical axis by a majority computation unit 21. When the number of car scans executed at the same position of the car body is an even number, and the result of majority decision for each optical axis is the same for "car body present" and "car body absent", the determination result of the optical axis is determined as "car body present".SELECTED DRAWING: Figure 2 【課題】車体検出動作と洗車動作とを並行して実行する洗車コースを行った場合にも、車形検出を行う上でノイズとなる飛散水による影響をできるだけ取り除いた車形データを作成することができる車形検出装置及びこの装置を備えた洗車機を提供する。【解決手段】洗車機本体１が走行移動する動作の中で、自動車車体の同一位置において車体検出を行う車両走査を複数回実行し、走査を行った回数分の車体データをいったん車体走査記憶部２２に記憶して、記憶したその車体データに関して各光軸Ｂの判定結果についての多数決判定を多数決演算部２１で行い、数が多い方の判定結果を当該光軸の判定結果として確定する。この時に、車体の同一位置において実行した車両走査の回数が偶数であって、さらに光軸ごとに多数決判定した結果が「車体有り」と「車体無し」とで同数となった場合には、「車体有り」として当該光軸の判定結果を確定する。【選択図】図２
