The all-new 2013 Cadillac XTS will begin production this spring and it will be the industry's first car to use what is called directional tactile sensation – a fancy way of saying vibrations of the driver's seat bottom will occur to warn of crash threats while driving and parking.
It works like this: the seat vibrates pulse patterns on either the right or left of the driver's seat bottom to alert the driver if they're drifting out of a lane or getting too close to an object while parking. In the event of a threat from the front or rear, the seat vibrates on both sides.
"It's akin to someone tapping on your shoulder in a crowd to get your attention," said, General Motors active safety technical fellow Raymond Kiefer. "Using the tactile sense to communicate crash threat direction provides an effective and intuitive way to cut through the clutter of visual and auditory sensory information that drivers routinely experience."
The Safety Alert Seat works with a variety of sensors and cameras installed in the car that help "intelligently" decide when to activate warnings. For example, if a turn signal is on, lane departure warnings are not presented. The seats also will be connected to the XTS Park Assist system and Rear Cross Traffic Alert system to help make parking in tight spaces easier.Read more
