Scope for the Integration of Powertrain and Chassis Control Systems: Traction Control - All-Wheel Drive - Active Suspension

摘要

In the past ten years there were two important developments in passenger vehicles which were virtually independent of each other: 1) the anti-slip control systems 2) the four-wheel drive. Since nearly two years we can see a focus in the development of another chassis control system, that means 3) active suspension. Each system has its own benefits to the customer, but it seems to that a functional integration of these systems might have additional benefits. The first stage of getting benefit is the common usage of sensors. The sensors used in traction control and in active suspension are not congruent. The next stage of getting benefit is the functional integration of different control systems. Therefore, this paper reviews the actual development situation of the single systems and tries to evaluate the possible advantages by combining the systems. Measurements were made to show some advantages by the functional integration.
