General Motors Co.'s Cadillac unit says it has begun testing its expanding "super cruise" semi-autonomous driving technology on real roads.
The latest system combines radar, ultrasonic sensors, cameras and GPS map data to enable a vehicle to control its speed, braking and in-lane steering.
GM says super cruise is likely to go into production before the end of the decade, but not until considerably more testing is completed. The system is being designed to work in bumper-to-bumper traffic and on freeways. Future tests will include night driving and a wide variety of weather, traffic and road conditions.
The company emphasize that the feature will permit hands-free driving only when it determines it's safe to do so. The system will warn the driver to resume control when it lacks enough reliable data to operate autonomously.
Researchers note that a key challenge is to make sure the driver can quickly resume command of the vehicle when necessary. They are using simulators to develop techniques to limit the driver's "secondary task behavior" when super cruise is active.
