Abstract: A two-channel antiblocking system for the driven wheels of an axle in which either an electronic decoupling system is connected downstream of the channels, or the channels are fed the sum (channel 1) or the difference (channel 2) of the wheel speed signals, specific controllers being used for the sum and difference, and the outputs of these controllers being on the one hand added to the actuating signal for the first channel and, on the other hand, subtracted from the actuating signal for the second channel. The aim of both measures is to compensate at least partially the coupling, caused by the differential, that is present between two drive wheels.

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.

Abstract: The goal of this concept is to adjust a wheel slip value, during a controlled braking of a vehicle wheel, at which, on the one hand, the coefficient of adhesion .mu. in the longitudinal direction is near the maximum attainable value, and on the other hand, an adequate coefficient of adhesion is available in the transverse direction. This slip value is below the value at which the coefficient of adhesion in the longitudinal direction is at a maximum. While at the maximum coefficient of adhesion in the longitudinal direction the wheel slip curve .mu. (.lambda.) has a slope of zero, .mu. (.lambda.) assumes positive slopes at the slip value to be adjusted. In addition to the advantage of greater cornering forces, the concept presented offers the opportunity of purposefully limiting the yawning moments engaging the vehicle during controlled braking and thereby improving control of the vehicle.
