A method and an apparatus for determining the position of a wheel mounted on a vehicle, wherein at least two target locations on the wheel are irradiated by a transmitter from a given location. The beams are reflected at the target locations and received by a receiver at a given location. The wheel position is ascertained from the measurement values produced by that arrangement, with signals associated with the respective target locations being emitted at given times and the periods of time from emission to reception of the signals reflected at the respective target locations being measured so the wheel position is determined from the measured times.

1. A method of determining the position of a wheel mounted on a motor vehicle, comprisingirradiating the wheel by first and second beams aimed at first and second diametrically spaced target locations on the wheel which are associated, respectively, with different given wheel position angles, wherein said first and second beams are emitted at the same time with spatially fixed predetermined irradiation and reflection directions from a transmitter maintained in one stationary position on one side of an axis of the wheel at least during the emission of said first and second beams, and wherein the said first and second beams directed, respectively, to said target locations relating said different given wheel position angles involve different signal characteristics, receiving the first and second beams reflected by the target locations on the wheel by a receiver at a given location on an opposite side of the wheel axis, which receiver is in a stationary position at least during the reception of said first and second beams, measuring the first and second beam transit times from emission from the transmitter to reception at the receiver, and determining the wheel position angle from said given stationary positions of the transmitter and the receiver, the predetermined irradiation and reflection directions and the measured beam transit times of said first and second beams.
