Abstract
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, will be launched by Jaguar in the supercharged XKR sports car, in European markets from September this year. This paper describes Jaguar's particular ACC implementation, covering the system architecture, braking system, control system, sensor system and driver interface. (A*)
