System and method for monitoring the wheels of a motor vehicle
First Claim
1. A system for monitoring the wheels of a motor vehicle for fault states, wherein each wheel to be monitored being assigned a wheel unit which, after the reception of a trigger signal supplies data which is suitable for detecting a fault state and/or for determining the wheel position of at least one wheel, the system comprising a portable transmitter with which a trigger signal, in particular a radio-frequency trigger signal, can be generated for at least one wheel unit, wherein in order to determine the wheel position of a wheel, the triggered wheel unit transmits an identifier to a central evaluation device of the vehicle, which simultaneously receives the trigger signal which is emitted by the portable transmitter and is assigned to a specific wheel position.

Abstract
The invention relates to a system for monitoring the wheels (R1, R2, R3, R4) of a motor vehicle (10) for fault states, in particular for incorrect tire pressures, each wheel (R1, R2, R3, R4) to be monitored being assigned a wheel unit (E1, E2, E3, E4) which, after the reception of a trigger signal (TR), supplies data (D1, D2, D3, D4) which is suitable for detecting a fault state and/or for determining the wheel position (FL, FR, RL, RR) of at least one wheel (R1, R2, R3, R4). There is provision for a portable transmitter (12) which can be included with which a trigger signal (TR), in particular a radio-frequency trigger signal, can be generated for at least one wheel unit (E1, E2, E3, E4).
