The long-delayed Cadillac Super Cruise system will be arriving as an option for the 2018 CT6 this fall. Described as "the industry’s first true hands-free driving technology for the highway,"(Tesla would argue otherwise) Super Cruise combines the driver assistance features currently on the CT6, along with a driver attention system and LiDAR-based mapping data.
Unlike other systems that monitor forces on the steering wheel to see if the driver is paying attention, Super Cruise uses a camera mounted on the steering column to monitor a driver's head position and movement. If it detects the driver has turned their head away from the road, the system will issue an alert to have the driver bring their eyes back to the road via a light bar on the steering wheel and then the safety alert system. If the driver fails to do this, Super Cruise will bring the car to a stop and call OnStar “if necessary.”
As for the "LiDAR-based mapping data", this scan of limited-access highways in the U.S. and Canada is paired with an improved GPS system, real-time cameras, and sensors to determine whether or not the system can come on, along with keeping the vehicle on the road.
“American drivers travel twice as many miles on urban and suburban highways as they do on rural roads. Super Cruise™ allows hands-free driving and operates only within the environment where it has the most benefit. While it is technically possible for the technology to drive hands-free on other kinds of streets and roads, we feel strongly that this targeted approach is the best to build consumer and regulatory confidence and enthusiasm for advanced mobility,” said Barry Walkup, chief engineer for the system.
