Cadillac Semi-autonomous Driving System


By mid-decade you will be able to buy a Cadillac that features semi-autonomous driving system.

Called the Super Cruise, the system is currently under testing and offers fully automatic steering, braking and lane-centering in highway driving under certain optimal conditions. The idea is to reduce from the driver’s workload by leaving some of the jobs, well almost all of it, to the system. 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.

It doesn’t mean the driver is of no use anymore. The Super Cruise wouldn’t work in bad weather condition or poor road surface with bad signs.

Cadillac press release:

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. 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.

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. When reliable data is unavailable, the driver will need to steer.

GM and its research partners recently conducted a study funded by the Federal Highway Administration on human factors in semi-autonomous vehicle operation. When asked, some study participants expressed strong interest in having a vehicle that could drive itself, particularly for long trips when lane centering and full-speed range adaptive cruise control could help lighten the driver’s workload.

“The primary goal of GM’s autonomous and semi-autonomous vehicle development is safety,” Capp said. “In the coming years, autonomous driving systems paired with advanced safety systems could help eliminate the crash altogether by interceding on behalf of drivers before they’re even aware of a hazardous situation. More than ever, consumers will be able to trust their car to do the right thing.”
