Chinese automaker SAIC will use ZF’s new 4-D full-range radar in an SUV starting in 2022. It perceives the vehicle environment in four dimensions, including height. 

With an aperture angle of +/- 60°, ZF’s 4-D full-range radar is designed for city traffic, rural roads and highways. In addition to a range of 350 m, it offers high resolution in the four dimensions of distance, speed, horizontal angle (azimuth), and height (elevation angle). The 4-D detection of the traffic situation thus enables, for example, early detection of the end of a traffic jam under a bridge and appropriate braking. The edge of the road can also be detected. 

Compared to a mid-range radar, the new technology offers a combination of several MMIC (Monolithic Microwave Integrated Circuit) chips, so that a total of 192 instead of 12 channels are available. The detailed object detection enables, for example, the acquisition of around ten data points from a pedestrian and can even resolve the movement of individual limbs and thus detect the direction of movement.

ZF will produce the radar sensors in China starting in 2022 and supply them to SAIC for the R-series electric SUVs. “With its high object and scene detection and long range, full-range radar is an important key technology that meets the demanding requirements of Level 3 and Level 4 automated driving at a competitive price point,” said Christophe Marnat, head of ZF’s Electronics and ADAS Division.
