Abstract
A method for determining an item of fastening information of a wheel of a motor vehicle, wherein rotational movements of the wheel are detected by at least one sensor. The sensor provides a wheel speed signal to an electronic control unit, which determines the fastening information from the wheel speed signal. A first time-frequency transformation of the wheel speed signal is carried out, whereby a first transformation signal is generated, after which a second time-frequency transformation of the first transformation signal is carried out. A second transformation signal is generated, in particular after which a first fastening parameter is obtained from the second transformation signal, after which the fastening information is calculated/determined as a function of the second transformation signal and/or the first fastening parameter.
