The partially-remodeled version of Mazda Motor Corp's "CX-3" compact SUV (sport utility vehicle) comes with, as a standard feature, an automatic emergency braking system that supports nighttime pedestrians.
The new CX-3, which was released May 31, 2018, is the company's first vehicle equipped with an automatic emergency braking system supporting nighttime pedestrians.
As sensors that detect vehicles and pedestrians, the new CX-3's braking system, "Advanced Smart City Brake Support (Advanced SCBS)," uses a milliwave radar device and monocular camera. They are attached to the back side of the front emblem and the interior side of the upper part of the windshield, respectively.
The milliwave radar device and monocular camera are products of Denso Corp and Magna International Inc, respectively. The image processing chip of the monocular camera is "EyeQ3" of Israel-based Mobileye.
Nighttime pedestrians are detected by the monocular camera. To support nighttime pedestrians, in terms of software, the logic of detecting pedestrians was improved, enhancing the accuracy of recognizing pedestrians at night. Its hardware was also improved to increase the speed of exchanging data between the EyeQ3 image processing chip and memory.
Mazda plans to apply the improved monocular camera to other vehicles in stages so that their automatic braking systems support nighttime pedestrians.
