ABSTRACT:
A circuit arrangement for providing the reference value for generating the slip signals used to control the brake pressure in an antilocking control system for the wheel brakes of a vehicle, from the value of two wheel speed signals. A selector circuit feeds the wheel signal with the greater value to a memory to cause the memory to store this greater value as a reference value. A comparison circuit compares the values of each of the two wheel speed signals with the value stored in the memory and emits respective output signals whenever the value of either of the wheel speed signals exceeds or falls below the value stored in the memory. A logic circuit, which is responsive to the output signals from the comparison circuit and to signals indicating that the pressure control devices associated with the wheels from which the wheel speed signals are derived have responded, causes the reference value stored in the memory to be selectively varied according to one of a plurality of different time constants.
