Method and system for monitoring the wheels of a vehicle
First Claim
1. A method for monitoring the wheels of a motor vehicle for fault states, in which each wheel to be monitored is assigned a wheel unit which transmits data to a central evaluation device of the vehicle at least in response to a trigger signal, the occurrence of a fault state and the wheel position of the wheel at which the fault state has occurred being indicated, the detection and the indication of the wheel position of the wheel at which the fault state has occurred being triggered after the fault state has been indicated, wherein the wheel position of the wheel at which the fault state has occurred is detected without all the wheel positions being stored, and said detection comprises a further trigger signal being supplied to at least one wheel unit at a known wheel position.

Abstract
A method for monitoring the wheels (R1, R2, R3, R4) of a motor vehicle (10) for fault states, in particular for incorrect tire pressures, comprises the steps of: each wheel (E1, E2, E3, E4) to be monitored is assigned a wheel unit (E1, E2, E3, E4) which transmits data (D1, D2, D3, D4) to a central evaluation device (ECU) of the vehicle (10) at least in response to a trigger signal, the occurrence of a fault state and the wheel position (FL, FR, RL, RR) of the wheel (R1, R2, R3, R4) at which the fault state has occurred being indicated. The detection and the indication of the wheel position (FL, FR, RL, RR) of the wheel (R1, R2, R3, R4) at which the fault state has occurred can be triggered after the fault state has been indicated.

- 14. A system for monitoring the wheels of a motor vehicle for fault states having a plurality of wheel units and having a central evaluation device, each wheel to be monitored being assigned a wheel unit which transmits data to a central evaluation device of the vehicle at least in response to a trigger signal, the occurrence of a fault state and the wheel position of the wheel at which the fault state has occurred being indicated, and the detection and the indication of the wheel position of the wheel at which the fault state has occurred being triggered after the fault state has been indicated, wherein it has trigger means which, when activated, cause a further trigger signal to be supplied to at least one wheel at a known wheel position in order to detect, without storing all the wheel positions, the wheel position of the wheel at which the fault state has occurred.
