Self Study Programme 475 For internal use ESC Audi Audi Training Service Introduction Traction control and support systems based driver automatic braking make an important To Service personnel, knowledge of functional relationships is an important challenge. contribution to active safety in road traffic. Most of the time we do not even notice these Knowledge in this area are essential to be able to explain to the client commands and auxiliaries during everyday driving. functions for controlling functions for fault detection, to diagnosis and ultimately for troubleshooting. Recent years have seen a rapid development in the field of driver assistance systems. Technological advances, especially in the development and production of electronic This self study program is to teach you the fundamentals of these systems. components, are provided. Common use of sub functions of several systems, the exchange of information between different systems and various outbuildings are the logical consequence of this development. Illustration of development using the example of the size and weight of the unit ABS / ESC computer and hydraulic unit 475 001 from Bosch. Due to the change of the ESP designation ESC in 2012 at the Group level, the ESC These designations containing the abbreviation ESP will continue initially be used designation is used for the first time in this self study program. The designations of in the service of documents and systems. components, such that unit G419 ESP sensors are an exception here. 2 Summary basic knowledge of driving dynamics The pneumatic connection floor 5 System overview Classification systems 11 Control systems based on ABS / ESC The anti lock system ABS 12 electronic distributor of braking force EBV 21 Electronic differential lock EDS 23 Traction control ASR . 26 Torque control of external systems Electromechanical parking brake emergency brake function EPB 58 Cruise Co
