Abstract
An automated car wash system includes a device for recognizing the types of vehicles passing through the system. The vehicle type recognition device includes two ultrasonic sensors positioned above the vehicle pathway to determine a vehicle profile. A computer recognizes the vehicle profile and type by monitoring a relationship between signals present at each sensor. The computer communicates the vehicle type information to a dryer controller that controls the position of the dryer relative to the vehicle.
