Abstract

The disclosed invention makes use of a wheel speed signal to detect a wheel anomaly such as a loose wheel or a wheel with zero pressure. The wheel speed signal is used as a basis to determine a first and a second detection signal. A further basis for determining the first and second detection signals are a first and second reference signal, respectively. The anomaly of e.g. a loose wheel is detected, according to the teaching of the invention if at least one of the detection signals exceeds a threshold. In particular, the disclosure relates to methods, systems and computer program products to achieve the mentioned objective.
