During nearly the past ten years, the efforts of chassis engineers concentrated on the development of modern axle systems, such as the Mercedes Benz multi-link suspension, the Japanese different type double wishbone axles and the BMW integral axle, but the main engineers concentrated on the development of control systems. These control systems enhance driving comfort and driving safety. Safety is generated by influencing the adhesion the tyre and the road surface. These systems intend to minimize the adhesion required longitudinally, laterally and vertically in order to maximize reserves for accommodating additional longitudinal, lateral and vertical forces. Mostly chassis control systems have been developed systems have been developed in isolation and presented correspondingly as individual systems. Only a few attempts have been made to analyse the combined effects of various suspension control systems and to propose appropriate combinations. This paper discusses the correlation between control system efficiency and the input which is needed for reasons of system safety.
