The Impact of Different ABS-Philosophies on the Directional Behavior of Commercial Vehicles

During the most recent past, contributions to anti-lock systems have been continuously published reflecting on the multi-functional significance of these systems only in a limited way. It seems essential therefore, to compare the primary criteria of functionality to the costs precisely. The technical solutions carried into effect during the past and the present orientated towards variously different criteria of optimization.

The paper illustrates the particularities of the different control systems, like 2-, 4-and 6-channel systems with Individual Control, Select-Low Control or Modified Individual Control. The impact of the various ABS-philosophies on the directional control of heavy commercial vehicles will be analyzed, using driving maneuvers like “straight-ahead braking” or “braking in a turn” on homogeneous and split adhesion road surfaces.
