A distributed embedded control system for vehicles is a real-time system constituting measurements, signal analysis and control. The project aims at methods and procedures for definition and specification of functions and properties of sub-systems, and the content and form of interaction between the sub-systems. A general treatment is sought through a direct study of a number of vehicle dynamic and control systems. These include distribution on local computers in combination with coordination and optimization of the local control using a network. Adaptation to a realistic architecture and switching between different modes in the system are important aspects.
As part of this project, models describing the vehicle's dynamic behaviour has been developed. These models has been extended with various vehicle dynamics control systems; Anitlock Brake Systems, Traction Control, Adaptive Cruice Control and Yaw Control. These simulation models has been structured according to the proposed software structure for vehicle dynamics control system. That is a structure which decouples the driver from the actual driving and lets the computer system handle the car according to the intent of the driver. The idea behind this method is that a computer system can drive the car better than the average driver, especially in critical situations.
