To enable this expansion, Cadillac has strengthened its cartography. Unlike autopilot and the like pseudo-self-driving systems offered by the likes of NissanSuper Cruise strictly limits the places where the driver can use it. During the development of the system, Cadillac hired a company called Ushr, responsible for navigating every kilometer of limited access highway in the United States and Canada, using a laser scanner to record all lines, cabs tolls, curves, mergers, divisions and others. . It was used for a few days and easily used by a computer. The following map helps the car anticipate sharp turns, but its function is more important.
By matching the location of the car (with the help of GPS) to the map, Cadillac turns off the system where it is not certain that the system can handle driving. Maybe the car is coming to an end, or that it is approaching the toll, or that the five lanes of the Bay Bridge Bridge have divided into several highways of Berkeley and Oakland – all that requires more than staying between the lines and at a safe distance the car in front of us. About a third of a mile before the shutdown, the lights on the steering wheel change from green to red, the driver's seat buzzes and the dashboard says "Super Cruise disengaged, take back control."
For the first edition of Super Cruise in 2017, Cadillac and Ushr have listed only limited access highways, type ramps to access and exit. Now, he adds divided routes, which are not very simple. Cadillac and Ushr tweeted their mapping protocol to take into account some new features, including stop signs and traffic lights that you sometimes see on these roads. These fall under the Super Cruise Prohibition Zone because the system is not designed to handle them. But the car will cross uncontrolled intersections where it has priority.
This raises the specter of two Tesla accidents, one in may 2016 and one in March of this year. In each case, a driver using the Tesla autopilot system died after colliding with a truck that turned on his way. Neither driver was driving within seconds of the accident, and neither driver pressed the brakes before impact. It is unclear why the cars did not stop by themselves, but the defects of the radars they use are a plausible explanation. Cadillac uses the same type of radar, but the automaker's engineers have confidence in the safety of their systems.
"The extraordinary is the driver's attention system," says Mario Maiorana, chief engineer of Super Cruise. It refers to the infrared camera that is on the steering wheel and monitors the position of the driver's head and his gaze. A few seconds later, you will hear ringing in your seat, as well as visual and audible warnings allowing you to monitor the road, ignore them and the system will automatically shut down, turn on the hazard lights and slow down the stop. in his driver bottling, but most competing systems, including those from Tesla, rely on a torque sensor in the wheel to verify that the driver is paying attention to the configuration defeated by a well placed orange or by typing usually on the wheel without bothering to look at the road.
Super Cruise Drivers – the system is available only on the CT6 sedan and will switch to the CT5 sedan next year – so your dealer can get the necessary software upgrade to take advantage of the new added parts of the card. The process is free and takes about an hour. After that, Cadillac will send updated maps via live software updates from this summer and into the fall.
