AMSTERDAM – Mobileye N.V., a computer vision-based driver assistance systems company, announced its latest technology partnership with Volvo Car Corporation and Delphi Corporation. Beginning with the new 2008 Volvo S80, V70, and XC70, Mobileye debuts a first-ever combination of its advanced vehicle detection and lane detection technologies, all powered by the Mobileye EyeQT vision system on a chip. As a result, Mobileye technology plays a key role in three of Volvo’s all-new safety and driver-comfort features, including the world-first Volvo Driver Alert Control (DAC) system, Volvo’s Lane Departure Warning (LDW) system, and the Volvo Collision Warning with Auto Brake (CWAB) system.

The CWAB system has been designed to help avoid or at a minimum mitigate collisions due to driver distraction or inattention. Powered by Mobileye’s advanced computer-vision algorithms and Delphi’s long-range millimeter-wave radar for vehicle detection, CWAB is a vision-radar fusion system for autonomous emergency braking.

Mobileye’s part in the Volvo CWAB system begins with the Mobileye EyeQT vision system on a chip. This powerful processor analyzes the video stream from a Complementary Metal Oxide Semiconductor (CMOS) camera mounted on the windscreen, looking forward. The EyeQ chip runs Mobileye’s advanced vehicle detection algorithms on the received video, and together with Delphi’s 77 GHz radar powers a collision warning system that performs automatic braking in certain emergency situations.

When both vision and radar sensors agree that the situation is critical, the system activates a series of steps to avoid or mitigate the imminent collision. When the system anticipates an imminent collision with a vehicle ahead, it provides an audio-visual forward collision warning (FCW) and also pre-charges the brakes to make the driver’s braking more effective. If the driver still doesn’t brake, and the system determines that a collision is imminent, the brakes are automatically activated. CWAB is designed to lower the impact speed as much as possible and thereby reduce the risk of injury to the occupants of both vehicles.

Volvo’s fusion of the two sensors enables a highly robust emergency braking decision and eliminates the disadvantages inherent with pure radar or pure vision sensors. The vision-radar fusion offers numerous benefits, such as improved availability in various road conditions, including very curvy roads and a wider performance range that enables earlier warnings as well as a longer braking distance in emergency situations.
