Self Study Program 286 – New data bus systems – LIN, MOST, Bluetooth PDF. The constantly increasing demand for additional functions and convenience in the vehicle calls for the use of ever more  wide ranging electronics.

Whereas the first Audi A8 model introduced in 1994 required a maximum of only 15 control units for implementation of all vehicle functions, this number will increase five-fold in the Audi A8 ´03.

The increased use of electronics also required a new approach to data transfer between the individual control units. A first important step towards this was the introduction of the CAN data bus at Audi in the mid 1990s.

This system does however have its limitations, particularly with regard to the transmission rates involved in the infotainment sector. The only solution is therefore to employ transmission systems designed to deal with specific requirements. Service and diagnosis functions will also benefit from this development.
