A control system for a vehicle washing system is provided. The control system utilizes a plurality of sensors to determine the length of a vehicle, the position of a vehicle relative to a fixed track upon which a gantry travels, and the profile of a vehicle relative to the track. The control system preferably begins a vehicle washing routine by commanding a gantry to travel from a beginning of the track to the end of the track while awaiting the interruption of an photoelectric beam for an entrance eye which first detects the front end of a stationary vehicle within the vehicle washing area. The gantry continues to move towards the end of the track while awaiting detection of a portion of the vehicle which is higher than a preset distance from ground. Upon detection of such vehicle portion, the control system establishes parameters setting a front safe tilt zone. In similar manner, the control system determines a rear safe tilt position for the vehicle washing system. Thereby providing a vehicle washing system which may process along a length of vehicle with deployed washing members while ensuring contact between such members and the vehicle is avoided.
