<P>PROBLEM TO BE SOLVED: To provide a car washing machine which controls contact/separation of brushes by current values of brush motors, wherein the car washing machine is configured to be able to use a freezing preventing measure that brings the brushes into contact with an abutting member. <P>SOLUTION: In the car washing machine which controls contact/separation of the washing brushes 5 and 6 by the current values of the brush motors 15 and 25, a first current threshold value is set according to the current value of a case in which the brush motors 15 and 25 are rotated at the positions where the washing brushes 5 and 6 can contact parts other than a car body, a second current threshold value is set according to the current value of a case in which the brush motors 15 and 25 are rotated at the positions where the washing brushes cannot contact the parts other than the car body, and a reference threshold value for determining the contact with the car body is switched in accordance with the moving positions of the washing brushes 5 and 6. <P>COPYRIGHT: (C)2013,JPO&INPIT |
