Subaru uses Xilinx chips in central driver assistance system
In its new Levorg SUV model, the Japanese vehicle manufacturer Subaru uses the principle of optical recognition by stereo camera for numerous driver assistance functions. The central control element of this driver assistance system called EyeSight is a multiprocessor SoC (MPSoC) from Xilinx.

The EyeSight system, produced by the tier-one supplier Veoneer, serves as the linchpin for sophisticated functions such as adaptive cruise control, lane keeping assistance and pre-collision braking. The system is largely based on a stereo camera that is installed near the rear-view mirror. This sensor generates huge amounts of data, which are pre-processed and fused in real time with a Xilinx-MPSoC of the Zynq UltraScale family. A three-dimensional point cloud is provided at the output, from which a downstream computer generates the driving commands. Since this process is extremely safety-critical, the entire data fusion process must be practically without any delay.

The EyeSight system is the basis not only for the driver assistance functions mentioned above; it is also instrumental for algorithmic support in the detection of critical situations such as the detection of pedestrians on the road, danger of collision when turning or unintentional vehicle movement, and for monitoring the driver's ability to drive (via a separate interior camera with its own data processing). Subaru is considering equipping the vehicle with four additional short-range radars as an option in order to implement further functions such as congestion assistant and curve prediction; these sensors would also interact closely with the Eyesight system.
