Cadillac has announced a new patented technology called Safety Alert Seat will debut on the all-new Cadillac XTS sedan when production begins this spring.

An industry first, the Safety Alert Seat uses "directional tactile sensation" to warn of crash threats while driving and parking. In other words, the driver will feel pulsing vibration patterns in the seat bottom to alert the driver of potential dangerour situation, such as drifting from a traffic lane without using a turn signal or moving towards nearby objects while parking. The vibration pulse patterns are felt from the left and/or right side of the lower bolster.

"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 system works in tandem with other active safety and driver assist systems such as Forward Collision Alert, Lane Departure Warning, Side Blind Zone Alert and Rear Cross Traffic Alert.

Kiefer adds, "Vibrating alerts also may help drivers who do not hear beeping alerts due to hearing loss or competing noises, and may be preferred by drivers and passengers who might be annoyed by beeps and shut crash avoidance features off," Kiefer said. "The last thing we want is for drivers to turn off features with safety benefits."

The Safety Alert Seat is part of the Drive Assist Awareness and Driver Assist packages and will be available this year also in the Cadillac ATS sedan and SRX crossover.
