Cadillac
is road testing a semi-autonomous technology it calls “Super Cruise”
that is capable of fully automatic steering, braking and lane-centering
in highway driving under certain optimal conditions. The system could be ready for production vehicles by mid-decade,
according to the company, which added that Super Cruise is designed to
ease the driver’s workload on the freeway, in both bumper-to-bumper
traffic and on long road trips, by relying on a fusion of radar,
ultrasonic sensors, cameras and GPS map data. “Super Cruise has the potential to improve driver performance and
enjoyment,” said Don Butler, vice president of Cadillac marketing, in a
statement. Many of the building block technologies for Super Cruise are already available on the all-new 2013 Cadillac XTS and ATS
luxury sedans, as part of the available Driver Assist Package,
according to the company. It is the first Cadillac system to use sensor
fusion to provide 360 degrees of crash risk detection and enhanced
driver assist features, including:
- Rear Automatic Braking
- Full-Speed Range Adaptive Cruise Control
- Intelligent Brake Assist
- Forward Collision Alert
- Safety Alert Seat
- Automatic Collision Preparation
- Lane Departure Warning
- Side Blind Zone Alert
- Rear Cross Traffic Alert
- Adaptive Forward Lighting
- Rear Vision Camera With Dynamic Guidelines
- Head Up Display
The key to delivering semi-autonomous capability will be the
integration of lane-centering technology that relies on forward-looking
cameras to detect lane markings and GPS map data to detect curves and
other road characteristics, said John Capp, General Motors director of
global active safety electronics and innovation, in a statement. Even when semi-autonomous driving capability is available on
vehicles, the system will have operational limitations based on external
factors such as weather and visibility of lane markings, according to
the company. It added that when reliable data is unavailable, the driver
will need to steer.
