Arrangement for monitoring the operating state of vehicle pneumatic tires mounted on wheel rims
First Claim
1. System for monitoring the operating state of vehicle pneumatic tires, which are comprised of tire material and have tire beads and side walls, mounted on wheel rims comprising:
- sensors for detecting either the air pressure of the air temperature in each tire, and not both;
transmitting means comprising rim-side mounted rotor members and bodywork-side mounted stator members coupled thereto for transmitting the parameters detected by said sensors to an evaluating arrangement in a vehicle connected to the stator members;
a first transponder, coupled to said temperature sensor or said pressure sensor, but not both, which in response to an interrogation signal generated by the evaluating arrangement, transmits either temperature data or pressure data supplied to said transponder by the sensor to the rotor members of the transmitting means;
a second transponder, which is disposed in the pneumatic tires, and which, in response to an interrogation signal generated by the evaluating arrangement, transmits data to the stator members designating the type of the pneumatic tire.

Abstract
An arrangement for monitoring the operating state of vehicle pneumatic tires (14) mounted on wheel rims (10) is provided with sensors (40, 42) for detecting the air pressure and the air temperature in each tire. Furthermore, it includes transmitting means comprising rim-side mounted rotor members (28) and bodywork-side mounted stator members (32) coupled thereto for transmitting the parameters detected by the sensor (40, 42) to an evaluating arrangement in the vehicle connected to the stator members. The pressure sensor (40) and the temperature sensor (42) of each tire (14) are coupled to a first transponder (44) which as reaction to an interrogation signal generated by the evaluating arrangement transmits the data supplied to it by the pressure sensor (40) and the temperature sensor (42) to the rotor members (28) of the transmitting means. Disposed in the pneumatic tire (14) is a second transponder (48) which when it receives the interrogation signal transmits data designating the type of the pneumatic tire (14) to the stator members (32).
