Abstract

A receiving antenna with a rigid directional pattern, that is to say with an anisotropic receiving sensitivity of the receiving antenna, is used for localizing a wheel electronics unit in a wheel of the motor vehicle. Suitable evaluation of the received electromagnetic signals is provided in order to obtain a functionality achieved by way of the displacement or rotation of the directional antenna in the case of prior solutions. In this respect, a level of the received electromagnetic signal is compared with a predefined threshold value. As the result of the comparison, the wheel electronics unit is localized as being arranged in a wheel of the first wheel group or as being arranged in a wheel of the second wheel group.
