CAR WASHING DEVICE

PROBLEM TO BE SOLVED: To provide a car washing device capable of surely recognizing a self traveling state of an own car at necessary timing during car washing, without performing wasteful free running.SOLUTION: A car washing device comprises self-traveling state detection means. The self-traveling state detection means continuously detects travel positions of a body frame, using a travel encoder during moving forward time of the body frame from a start point SP where a first vehicle sensor 10 detects a vehicle body while a vehicle shape sensor 9 and a second vehicle sensor 11 do not detect the vehicle body; and determines that the car is in a self-traveling state when a distance a between a travel position P1 where the vehicle shape sensor 9 detects the vehicle body, and a travel position P2 where the second vehicle body sensor 11 detects the vehicle body, is different from a distance A between installed positions of the vehicle shape sensor 9 and the second vehicle sensor 11; and also determines that the car is in the self-traveling state when a distance b between a travel position P3 where the first vehicle sensor 10 comes to detect no vehicle body, and a travel position P4 where the vehicle shape sensor 9 comes to no longer detect the vehicle body, is different from a distance B between installed positions of the first vehicle body sensor 10 and the vehicle shape sensor 9.SELECTED DRAWING: Figure 4 【課題】無駄な空走を行わず、洗車中の必要なタイミングで自動車の自走を確実に認識することができる洗車装置を提供する。【解決手段】自走検出手段を備えた洗車機であって、自走検出手段は、第１車体センサ１０で車体を検出し、車形センサ９及び第２車体センサ１１で車体を非検出となっている状態を起点ＳＰとする本体フレームの往行時に、走行エンコーダで本体フレームの走行位置を検出していき、車形センサ９で車体を検出したときの走行位置Ｐ１と、第２車体センサ１１で車体を検出したときの走行位置Ｐ２との距離ａが車形センサ９と第２車体センサ１１の設置間隔Ａと異なるとき自動車の自走を判断するとともに、第１車体センサ１０で車体を非検出となったときの走行位置Ｐ３と車形センサ９で車体を非検出となったときの走行位置Ｐ４との距離ｂが第１車体センサ１０と車形センサ９の設置間隔Ｂと異なるとき自動車の自走を判断する。【選択図】図４
