Stability and reliability within the electrical system are an The number of electronic control units has grown rapidly in recent important basis for system quality in a situation where the number years. Most of today s innovations have only been made possible of electronic systems and components are increasing. by the increasingly higher performance of the electronic systems. With an overall weight of as much as 50 kilogrammes, around Without that development, many vehicle comforts and 1,500 individual leads with an average length of approx. 2 metres, conveniences that are now taken for granted would not have been numerous contacts, switches, seals, fuse boxes and wiring ducts, achievable. the electrical system is one of the largest, heaviest and most In comparison with its predecessor, the Audi A8 ’10 features the expensive parts of a motor vehicle. Nowadays, the electrical following most noticeable differences system plays a major role in ensuring the high quality standards the number of control units has increased from 68 to 95 demanded of the electrics/electronics at Audi. a new bus system, the FlexRay, has increased the number of bus Against the background of present day energy and environmental systems from 6 to 7 considerations, the development of new, lighter electrical system the volume of software on the vehicle now exceeds 230 MB, components is extremely important, as weight is a major factor in which is almost four times the amount on the previous model fuel consumption and, therefore, CO emissions. 2 459 025 Learning objectives of this Self study Programme This Self study Programme informs you about the network In what locations are electrical components fitted on the topology of the Audi A8’10.
