First Claim
Patent Images
1. A device for ascertaining a wheel position of wheels on a wheeled vehicle, the device comprising:
- separate wheeled-vehicle-side wheel units each respectively assigned to one of the wheels for monitoring purposes and respectively receiving monitoring data of an assigned wheel;
a vehicle bus connected to said separate wheel units;
a central control and analysis unit connected through said vehicle bus to each of said separate wheel units for an exchange of data; and
a supply lead system connected to and supplying said separate wheel units with energy;
said central control and analysis unit connecting said separate wheel units successively to said supply lead system for an energy supply in a defined sequence and assigning a new individual identity code to a respectively connected wheel unit.

Abstract
Devices and methods are used for ascertaining wheel positions of wheels on a wheeled vehicle. Separate wheel units are connected to each other via a vehicle bus and via an additional supply lead, so that for the purposes of learning the separate wheel units, the separate wheel units are connected to the supply lead successively in a predetermined sequence and provided with a new, individual identity code, or subjected to a wheel-unit-specific dc voltage potential as an identity code by using at least one additional connection.

12. A method for ascertaining a wheel position of wheels on a wheeled vehicle, separate wheel units each being respectively assigned for monitoring purposes to each of the wheels and respectively connected to a central control and analysis unit for an exchange of data, which comprises the steps of:
-
each time the wheeled vehicle is put into operation; connecting the separate wheel units in a defined sequence to a supply lead system for supplying energy to the separate wheel units by the central control and analysis unit; and assigning a new, individual identity code to the respectively connected wheel unit by the central control and analysis unit and; and identifying each of the separate wheel units with the individual identity code assigned thereto during a current operation of the vehicle, ascertaining the wheel position of the wheels on the wheeled vehicle in accordance with the identity codes assigned to the wheel units, and outputting a signal with the wheel position of at least one wheel on the wheeled vehicle. - View Dependent Claims (13, 14)
