Infineon 77GHz Radar Chips Equip Audi A8 for Level Three Driver Assistance

Infineon says it is supplying radar sensor chips for use in the first commercially released level three driver assist vehicle, the Audi A8. Level three driver assistance allows drivers to take their hands off the steering wheel under particular conditions such as in slow traffic, and when parking. Systems with this level of driver assistance offer collision warning and adaptive cruise control. (Level five will be fully autonomous).

According to Infineon the adaptive cruise control and collision warning can recognize objects at a range of up to 250 meters. Infineon points out that with 15 million chips already shipped, they are the leader in radar chips. Among the chips are the RTN7735PL (a three-channel transmitter) and RRN7745PL/46PL (a four-channel receiver) that offer a 77 GHz solution in an eWLB package.

A radar-based driver assistance system is mandatory for the independent Euro NCAP (European New Car Assessment Program) organization to give a vehicle the highest rating of five stars. The Euro NCAP organization reviews the safety of new vehicles sold in Europe.
