Serial communications within vehicles has emerged as the enabling technology for the next generation of electrical vehicle architecture. Currently, many of the major automotive companies are evaluating serial communications as a solution for delivering real-time control powertrain system functions. Amongst the front runners is Jaguar. This paper highlights how Jaguar has successfully implemented high speed serial communications technology, controller area network, to enable communications between powertrain subsystems entailing anti-lock braking system, engine control module, transmission control module and instrument pack. This high speed network is the core of the vehicle electrical system which enables enhanced feature and refinement of vehicle functions and service bay diagnostics, allowing the XK8 to meet all current emissions legislation, whilst maintaining best in class drivability.
