Abstract:
1. A device for localizing a wheel electronics unit in a motor vehicle having a first wheel group and a second wheel group shifted with respect to the first wheel group in a direction of travel of the motor vehicle, the device comprising: a wheel electronics unit disposed in a wheel of the first wheel group and/or in a wheel of the second wheel group, said first wheel electronics unit having a transmitting device; a rigid, directionally sensitive receiving antenna disposed substantially centrally between the first wheel group and the second wheel group, within a given margin of tolerance, with reference to the direction of travel of the motor vehicle, said receiving antenna having an anisotropic receiving pattern for receiving an electromagnetic signal from said transmitting device of said first wheel electronics unit, and said receiving antenna exhibiting a higher receiving sensitivity in the direction of travel of the motor vehicle than transversely to the direction of travel; an evaluation device for evaluating an electromagnetic signal received by said receiving antenna by way of comparing a level of the electromagnetic signal with a predetermined threshold value, said evaluation device assigning the wheel electronics unit to a wheel of the first wheel group if the level is greater than the predetermined threshold value, and/or assigning the wheel electronics unit to a wheel of the second wheel group if the level is less than the predetermined threshold value.
