Abstract

The disclosure relates to a sensor arrangement for a vehicle having at least one rotation-speed detection apparatus, which continuously detects a state variable and outputs said state variable to an evaluation and control unit which receives and evaluates signals which are output by a rotation-speed detection apparatus, wherein the evaluation and control unit carries out a first evaluation process with the detected state variable and ascertains a rotation speed of at least one vehicle wheel, the rim of said vehicle wheel being fastened to a corresponding wheel hub by means of wheel fastening means. According to the disclosure, the evaluation and control unit carries out a second evaluation process and identifies and monitors, on the basis of the continuously detected state variable, mechanical play between the vehicle wheel and the corresponding wheel hub in order to detect detached wheel fastening means.
