Abstract

A method for determining the wheel position (FL, FR, RL, RR) of wheels (R1, R2, R3, R4) of a motor vehicle (10) which, for monitoring purposes, in particular for monitoring the tire pressures, are each 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 (TR1, TR2, TR3, TR4, TR5, TR6). The wheel positions (FL, FR, RL, RR) of the monitored wheels (R1, R2, R3, R4) can be determined by activating a portable transmitter (12) whose position with respect to the vehicle (10) is sensed.
