Infineon Technologies has announced that it supplies key components for the Audi A8, the first series production car featuring level 3 automated driving. The ability of cars to self-drive is split into a number of different levels: With level 3, drivers can temporarily take their hands off the steering wheel under certain conditions. The Audi A8 allows this when parking and exiting, in slow-moving traffic or in traffic congestion. Using microelectronics from Infineon Technologies, a car can take over in this kind of driving situation.
Various types of chips from Infineon serve the safe automated driving in the Audi A8: sensors, microcontrollers and power semiconductors. Radar sensor chips from the RASIC family are installed in the front and corner radar. They send and receive high-frequency 77-GHz signals and forward these on to the central driver assistance controller (zFAS).
AURIX microcontrollers are used in several controllers in the Audi A8: On the one hand, they control the functions for the engine. On the other, they operate in the Audi AI active chassis and in the electronic chassis platform, which controls the shock absorption. The microcontrollers also support activation of the airbag.
In addition to the electronics for drive, driver assistance and chassis, other semiconductor solutions from Infineon are installed in the comfort and body electronics, such as for example LED drivers from the LITIX Basic family in the tail lights as well as bridge drivers from the Embedded Power family in the windscreen wipers.
