Abstract
At certain operating points, a plausibility test of the detected rotational speed signals is used to recognize an existing defect. The operating point for implementing the plausibility test is determined when it is detected that the motor vehicle has accelerated. The operating point at which defects in speed sensors are detected is determined in a simple manner but in such a way that any defect which may be present can be recognized reliably.
