Next Generation Driving Assist System Using New Stereo Camera
Subaru developed a next generation driving assist system that realized pre-crush safety function for objects including pedestrians and Full Speed Range Adaptive Cruise Control (FSR-ACC) by only using new stereo camera. In 1999, we commercialized the world´s first driving assist system using stereo camera. Since then, this system has been evolved as one of the Subaru´s unique safety technologies.
The new stereo camera has dramatically improved recognition performance and high reliability in bad weather conditions that was seen as a defect of conventional camera sensor. In addition, a newly developed stereo image processing LSI (Neo 3D Core) was built in the stereo camera unit. This actualized the compact and cost effective stereo camera.
The next generation driving assist system with the new stereo camera can detect various objects on the road such as forward vehicles, bicycles, pedestrians, guardrails, or driving lanes in the horizontal range with high accuracy. The system also gives appropriate warning and brake control for offset collision that are difficult to conduct by the current system.
All these features helped to realize the pre-crush safety function for not only vehicles but also vulnerable road users such as bicycles or pedestrians, and FSR-ACC that can select a forward vehicle appropriately in various traffic situations.
This paper describes the construction, principle of operation, and functions of the next generation driving assist system.
