Abstract
A method for assigning a position of a tire, having a tire sensor, on a vehicle, includes transmitting, with the sensor, a signal including at least an identification number of the sensor following activation by a signal from an LF antenna connected to an evaluation unit. At a system start time, the evaluation unit first initiates an initialization including determination of the position of each tire having a sensor. The evaluation unit stores the identification number of each sensor together with the determined position of the tire having the sensor, before switching into a normal operating mode in which tire data, for example air pressure, is monitored by the sensors, with the position and preferably assignment of the sensor to a specific LF antenna, being stored in the sensor and kept available for retrieval. A device and a system for measuring air pressure in a vehicle tire are also provided.
