A technology formerly associated with military and aircraft applications – radar – is now an instrumental technology in modern cars, making vehicles safer by helping reduce the frequency of crashes.
This state-of-the-art technology was recognized by Automotive News as a 2017 PACE Award winner, marking the 19th time Delphi has earned this honor.
By opting to use a higher frequency radar than the industry standard, Delphi’s Short Range Radar (SRR) sensor enables a wider range of driver assist and safety technologies than other solutions.
Delphi’s high-performance, low-cost SRR sensor was the first-to-market 76 GHz radar initially introduced for side, blind spot warning applications. The higher, 76 GHz frequency is capable of providing 360-degree sensing around the vehicle, a capability the industry standard 24 GHz radar does not provide. The sensor offers a range coverage from 0 meters to 80 meters with excellent object discrimination in cluttered environment and spatial resolution.
OEMs require incredibly precise, “image-like” information about the position (length, width and extent) and edges of moving objects, as well as the stationary environment around the vehicle (360-degree coverage) to enable creation and implementation of initial automated features for lateral and longitudinal control of the vehicle (such as sideswipe prevention, virtual bumper, auto-parking and frontal cross traffic alert). Birds-eye view cameras do not provide the accuracy of range or position required. Existing 24 GHz radars used for blind spot detection are not capable of adequately discriminating edges of objects to define the available free space.
The Delphi SRR provides four enabling technologies for vehicle level features such as Side Blind Zone Alert, Front and Side Cross Traffic Alert, Lane Change Assist, Forward and Rear Collision Imminent Braking. The SRR is one of the key building blocks of sensors for automated driving.
