Patent number: 7222046Abstract: 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.Type: GrantFiled: April 19, 2005Date of Patent: May 22, 2007Assignee: Siemens AktiengesellschaftInventors: Martin Fischer, Manfred Fröhler, Franz Hillenmayer, Matthias Münch, Martin Prenninger, Dieter Wagner, Gero Wuttke

Publication number: 20060012475Abstract: The device and the method enable the localization of transponders, particularly in motor vehicles. A determination of the distance of different transponders from the base station is made possible by evaluating the different request signals and response signals received and also the physical variables contained therein, such as signal level, charging time, and signal propagation delay. As a result of the relative determination of the different distances of the transponders from a base station, it is for example possible to determine the position of wheels of a motor vehicle. This means savings in terms of tire electronics, which require a separate power supply and are technically more complicated and more expensive to use than transponders.Type: ApplicationFiled: July 19, 2005Publication date: January 19, 2006Inventors: Herbert Froitzheim, Matthias Munch, Dieter Wagner
