Robert Bosch GmbH will be employing a chip from Infineon Technologies in its next generation of automotive radar systems. Bosch, one of the world’s largest suppliers of components for the automotive industry, has chosen a chip from Infineon’s Radar System IC (RASIC™) product family for use in its new third-generation Long Range Radar (LRR3) sensor system.
The LRR3 has been developed for Adaptive Cruise Control at ranges up to 250 m and predictive radar-based safety functions such as predictive brake assist systems, collision warning features and automatic emergency braking. As Infineon produces the radar chip using silicon-germanium (SiGe) technology, it enables smaller and more cost-effective radar systems.
“The LRR3 radar system was specially developed for high-volume driver assistance systems, and for the first time makes use of silicon-germanium as the semiconductor material,” said Dirk Freundt, LRR3 project manager for Bosch. “By employing Infineon’s innovative radar chips and avoiding the use of costly special-purpose semiconductors, it has been possible to significantly enhance the functionality of the Bosch sensor, and considerably reduce system costs. Bosch is also looking to bring the radar sensor and its functions into the midrange and compact class, where it could soon be part of a car’s standard equipment.”
