Abstract

A brake slippage control is described where the difference .DELTA..lambda. between an acceptable brake slippage .lambda.* and the actual brake slippage is determined. The difference .DELTA..lambda. is supplied to a control amplifier and converted into actuating times for a brake pressure control unit. Magnitude and increase of the reference value required for forming the slippage values .lambda. and .lambda.* is from time to time actualized when the control is switched off.
