ABSTRACT:
A circuit configuration for evaluating signals from a yaw rate sensor is used in particular for movement stabilization in a motor vehicle. There is provided a controller which receives the signals from the yaw rate sensor and from further sensors. The further sensors detect motion state dependent variables, such as for example wheel speed, steering wheel angle, lateral acceleration and longitudinal acceleration. The controller calculates from one or more of these further sensors a reference yaw rate. The reference yaw rate is compared with the yaw rate measured by the yaw rate sensor. The plausibility of the yaw rate sensor signal is also checked, taking account of the motion state. If the difference between the measured yaw rate and the reference yaw rate determined in the plausibility check is above a predetermined threshold value, then the yaw rate sensor is identified as being faulty.
