GM Develops New Collision Warning System

Relies on low-cost, single-camera design.

by on Sep.30, 2011

The new GM crash-avoidance system relies on a single camera to help reduce the cost for mainstream buyers.

General Motors is planning to equip the 2012 GMC Terrain with the industry’s first, “affordable” crash avoidance system. The system is based on a single camera placed in front of the rear-view mirror to help drivers avoid front-end and un-signaled lane departure crashes.

It’s by no means the first collision avoidance system on the road, but the new technology significantly lowers the price compared to existing designs that may use multiple cameras, radar sensors or both, putting the system within the price range of mainstream, rather than luxury, buyers.

“Digital image sensors are used in just about everything from cameras to mobile phones to computers and this is making them a more-affordable alternative for use in vehicles,” said Raymond Kiefer, General Motors Technical Fellow for crash avoidance systems.  “By combining a digital camera with state-of-the-art image processing algorithms, we’re able to estimate when a crash may be imminent,” he said.

This dual-benefit crash avoidance system will cost $295, which is significantly less expensive than the systems now available in luxury cars, GM’s experts said. The maker developed the system with extensive help from suppliers, including Magna, TRW and Mobileye.
