"The 2012 GMC Terrain crossover SUV will feature a new crash avoidance system that'll also serve as a lane departure system, according to GM. It will be the first such system in a General Motors vehicle.
Unlike other precollision and lane departure systems, which typically use a series of radar or laser sensors to detect vehicles in front of them, the GMC system uses a digital camera mounted on the windshield in front of the rear-view mirror.
The digital camera, combined with object- and range-detecting software, determines if an accident is eminent. If it is, the system illuminates a warning icon and beeps to warn the driver. The system also will pre-charge the brakes, like other systems, if it deems an smashup as unavoidable. GM doesn't mention if the system will pre-emptively tighten seat belts, adjust seating position, raise head restraints or close the windows as similar systems do. GMC's precollision system only works at speeds above 25 miles per hour." [Continue reading...]
