ABSTRACT:
A control loop, preferably for movement stability regulation in a motor vehicle, has a yaw rate sensor supplying an electrical sensor signal and a temperature sensor supplying an electrical sensor signal for compensation of temperature dependency of the sensor signal of the yaw rate sensor. A circuit configuration for evaluation of the sensor signal of the yaw rate sensor includes a first evaluation device for calculating an instantaneous yaw rate from the electrical sensor signals of the yaw rate sensor and of the temperature sensor, and a second evaluation device for adaptively determining sensor-specific characteristic parameters of the yaw rate sensor as a function of temperature. A reference yaw rate .PSI..sub.ref being calculated from measured wheel rotation speed values v.sub.1 and v.sub.r in accordance with the following formula: ##EQU1## is taken into account, where l.sub.trackw designates a distance between two centers of contact of wheels on a non-driven axle with the ground.
