Method for Assigning a Tire Pressure Monitoring System After Driving Interruptions and Device and System for Measuring Air Pressure in a Vehicle Tire
First Claim
1. A method for assigning a position of a tire on a vehicle, the method comprising the following steps:
- providing an evaluation unit;
transmitting a receive signal with an LF antenna located at a predetermined position on the vehicle and connected to the evaluation unit;
providing the tire on the vehicle with a tire sensor having an individual identification number, and transmitting a transmit signal, including at least the identification number, with the tire sensor following activation by the receive signal;
first initiating with the evaluation unit, at a system start time, an initialization including determination of the position on the vehicle of each tire provided with a tire sensor;
storing the identification number of each tire sensor together with the position on the vehicle of the tire provided with the tire sensor as determined by the system, with the evaluation unit, before it switches over into a normal operating mode in which the tire sensors monitor tire data to be monitored; and
storing the position of the tire sensor on the vehicle in the tire sensor itself and keeping the position of the tire sensor available for retrieval.

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.
