Abstract
The proper functioning of a control system (such as an ABS, ASR) that secures the adhesion of the wheels, by analyzing wheel rotating speed signals, is determined by comparing acceleration signals determined from the wheel rotating speed signals with accelerated signals measured by acceleration sensors on the vehicle. If they do not correspond within given limits during absence of control system control signal, the control system is disabled by an error signal and a warning indicator is activated.
