Method and system for monitoring the wheels of a vehicle
First Claim
1. A method for monitoring the tire pressure in the wheels of a motor vehicle for fault states, in which a wheel unit is arranged in each wheel whose tire pressure is to be monitored comprising the steps of:
- transmitting tire pressure-data to a central evaluation device within the vehicle at least in response to a trigger signal, comparing the tire pressure-data with reference data by the central evaluation device to determine a fault state, detecting the wheel position of the wheel at which the fault state has occurred 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 wherein the occurrence of a fault state and the respective wheel position is displayed, and wherein the determination and the display of the wheel position is only triggered after the determination of a fault state.

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 tire pressure in the wheels of a motor vehicle for fault states comprising:
- a plurality of wheel units for determining the tire pressure, wherein each wheel unit is arranged within a wheel, a central evaluation device, wherein each wheel unit transmits tire-data to the central evaluation device of the vehicle at least in response to a trigger signal, and a signaling means for signaling the occurrence of a fault state and the wheel position of the wheel at which the fault state has occurred, and wherein 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, further comprising 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.
