Why Suzuki Did Not Use Stereo Camera for New Wagon R (2)
Continued from Why Suzuki Did Not Use Stereo Camera for New Wagon R (1)
Based on such experiences, for the new Wagon R, Suzuki employed a sensor unit integrating a monocular camera and an infrared laser device. The sensor unit is manufactured by Germany-based Continental. And it is the same product as the hardware that Toyota Motor Corp uses for the "Toyota Safety Sense C" automatic braking system for compact cars.
So, it can be said that the cost of the sensor unit has been lowered because Toyota procured the unit in large quantity. The partially-remodeled Outlander "PHEV," which Mitsubishi Motors Corp released in February 2017, also uses the same sensor unit.
On the other hand, the aforementioned stereo camera was co-developed by Suzuki and Hitachi Automotive Systems Ltd exclusively for Suzuki's vehicles and manufactured by Hitachi Automotive Systems.
The automatic braking system of the Wagon R is available as an option at a price of ¥59,400. Though it seems that the cost did not decrease, the price includes the head-up display that has been employed for a light car for the first time (See related article).
In terms of size reduction, I confirmed that the system can be compactly installed in front of the rear-view mirror of a real car.
For the "Swift" compact car, which was released in January 2017, Suzuki employed Continental's sensor integrating a monocular camera and an infrared laser device for the first time. This time, the company applied the knowhow to the Wagon R.
After replacing the stereo camera with a combination of the monocular camera and infrared laser device, Suzuki will probably focus on the capability to detect pedestrians during nighttime hours. In 2018, a test of automatic braking targeted at nighttime pedestrian detection is expected to be added to the "NCAP (New Car Assessment Program)" in Japan, Europe, etc.
"We are now comparing sensors in view of the future NCAP," the company said.
