Vehicle motion control is concerned with the study of the automotive vehicle viewed as a total system composed of interacting subsystems. It will entail the application of control action on a combination of - Propulsion control, - Steering control, and - Suspension control.
Conventionally, these subsystems have been treated separately. Future applications will follow a trend towards integrated vehicle control systems capable of coordinating the actions of the various subsystems present in a vehicle.
In order to address the vehicle motion control problem described, a combination of integratable computer tools is required which provides the capability for MBS model generation, nonlinear simulation and control analysis, usually based on linear system theory.
A particular combination of tools which adequately performs these tasks is SD/FAST, ACSL and MATLAB. Their use have been exemplified in the execution of the IAVSD road vehicle benchmark problems.
This paper describes aspects of this set of tools which have not been discussed or appropriately emphasized in the benchmark solutions.
