Nissan Motor Co Ltd employed Israel-based Mobileye's "EyeQ4" (latest version) as an image processing chip for the trinocular camera of its "Propilot 2.0" second-generation ADAS (advanced driver assistance system).

Nikkei xTech/Nikkei Automotive found this in an interview with Nissan at Automotive Engineering Exposition 2019, which took place from May 22 to 24, 2019, at Pacifico Yokohama.

The EyeQ4 has already been employed by BMW AG, Tesla Inc and China-based EV startup NIO as an image processing chip for their trinocular cameras. Nissan is the first Japanese automaker that has employed the EyeQ4. Though the company did not disclose the name of the supplier of the camera, it seems to be ZF Friedrichshafen AG (former TRW).

The employment of the EyeQ4 enabled the automatic brake of the Propilot 2.0 support nighttime pedestrians. Nissan's current "Propilot" system uses ZF's monocular camera as a sensor.

The monocular camera of the current system uses the "EyeQ3" (existing model) as an image processing chip, and its automatic brake does not support nighttime pedestrians because the processing speed of the chip is not high enough.

The processing speed of the EyeQ4 is 2.5TOPS, which is about 10 times higher than that of the EyeQ3. The employment of the chip capable of processing a large amount of information at high speed enabled the automatic brake of the Propilot 2.0 to support nighttime pedestrians.

The Propilot 2.0 enables the driver to leave his/her hands off from the steering wheel when the vehicle is running on the same lane of an expressway and helps the driver to change lanes and pass another vehicle in conjunction with a navigation system.
