ABSTRACT:
A circuit configuration for brake systems with anti-lock control and/or traction slip control is equipped with circuits for cornering identification and for generating signals characteristic of cornering. The differential speed between the wheels of one axle is measured. The speed difference signal is standardized. An error signal which is system-inherent and occurs also when driving straight ahead is generated by means of a low pass filter having a long time constant. The difference between the standardized speed difference signal and the error signal represents the cornering signal. Further, a quantity depending upon the speed of a wheel is compared with the cornering signal and checked for reasonableness. A second reasonableness check is based on the comparison and the evaluation of the cornering signals which were generated by the front axle and the rear axle irrespective of one another.
