Patent ID: 8163097

Claim:
A method for controlling the movement of a horizontal brush of a vehicle washing system, said method including the steps of: providing a first and a second vector velocity control mode of said brush; providing an alternating logic between said first and second vector velocity control mode, wherein said first vector velocity control mode is based on the control of the absorption current of the rotation motor of said brush and said second control mode being based on the geometric limitation of the position of said brush wherein said second control mode provides for acquiring the profile of the vehicle to be washed and, starting from the acquired profile of the vehicle, processing in real time a gauge profile for the geometric limitation of the position of said brush on said vehicle over the entire profile covered by said brush; calculating, starting from said acquired profile of the vehicle, the inclination value of said profile of the vehicle during said second control mode, to be used during said first control mode in order to obtain an initial value indispensable to guarantee smooth switching between said first and second control modes without discontinuity; and generating a forced movement of said brush by geometrically modifying said calculated gauge profile.
