Self Study Program 668 – Audi A8 (type 4N) driver assistance systems

VAG SSP 668 – Audi A8 (Type 4N) Driver Assistance Systems: Innovations and Advancements in Sensor Technology. Self Study Program 668 covers the driver assistance systems of the Audi A8 (Type 4N), the innovative successor to the successful 4th generation A8. Each new model of the A8 introduces innovative solutions and new automotive systems, broadening the spectrum of driver assistance systems and extending the range of situations in which drivers are assisted by cutting-edge technology.

The 5th generation of the Audi A8 includes new features such as intersection assist and adaptive cruise assist, which provide longitudinal and lateral control assistance over a continuous speed range from 0 to 250 kph. The new laser scanner, located at the front end of the vehicle, enhances the performance of existing systems by precisely surveying the area in front of the vehicle.

The Audi A8 (Type 4N) utilizes a central driver assistance systems control unit (J1121) for the first time at Audi, which acts as the master control unit for multiple assistance systems. Several sensors are connected directly to the control unit, with sensor data processed in control unit J1121. This allows for high-quality data on the area around the vehicle, improving the performance of driver assistance systems.

Self Study Program 668 provides a detailed look at the driver assistance systems of the Audi A8 (Type 4N), making it a valuable resource for technicians and enthusiasts interested in understanding the innovative solutions and advancements in sensor technology of Audi’s latest flagship model. The program covers intersection assist, adaptive cruise assist, the new laser scanner, and the central driver assistance systems control unit (J1121).

With its advanced driver assistance systems and innovative solutions, the Audi A8 (Type 4N) is a luxurious and safe sedan that offers both style and performance. Its use of cutting-edge technology and advanced sensor systems make it a modern and efficient vehicle, while its driver assist systems provide safety and convenience on the road.
