Application of control system simulation in the automotive industry

Longitudinal driver support systems have been under development for a number of years. Conventional cruise control, which, when activated, keeps the speed of the vehicle constant, is an established feature. Adaptive cruise control (ACC), where distance-keeping is added to the basic speed control function, has been launched by Jaguar in the supercharged XKR sports car. This paper describes Jaguar's particular ACC implementation, briefly covering the system architecture, braking system, sensor system and driver interface. The development of the control system for ACC and the use of simulation and rapid prototyping techniques are discussed in more depth.
