Our high system knowledge and close cooperation with leading system suppliers and car manufacturers around the world are key elements to our success," says Hanebeck.
Broad product portfolio for radar-based driver assistance systems from short to long vicinity range.
Even in poor visibility situations, radar chips in the 77-GHz range make it possible for vehicles to "recognise" other road users at a distance of up to 250 meters (approx. 275 yards). This allows a car to indicate a hazardous traffic situation in time and brake automatically.
If radar-based driver assistance systems continue to become widely adopted, then those dreaded collisions you get when stuck in a traffic jam - especially around vacation time - could well be a thing of the past.
In addition to 77-GHz radar chips for active safety systems, Infineon also offers radar chips in the 24-GHz frequency range for distances up to 100 meters (approx. 110 yards). 24-GHz radar chips are most often used to monitor the blind spot. With them, the radar system alerts drivers to vehicles behind them when passing or changing lanes. When parking, the radar detects cross-traffic in the rear and prevents collisions.
How radar technology works in the car
A vehicle driver assistance radar system sends out radio-frequency electromagnetic waves, which are reflected back by vehicles or other objects ahead. Radar chips of Infineon send and receive these high-frequency signals and pass them on to the radar electronic control unit (ECU). The radar ECU then determines the distance of the car to other vehicles and their speed in order to warn the driver in good time and to initiate the braking maneuver in case of emergency.
"Made in Germany" innovation
Ever since 2009, Infineon manufactures its radar chips in Regensburg, the company's innovation center for high frequency technology in Germany. Here the radar chips are integrated in special chip packaging and tested. The use of the silicon germanium manufacturing technology developed by Infineon helps make radar sensor systems that are more compact and cost-effective.
