Cadillac semi-autonomous driving with Super Cruise

Starting this fall in the United States and Canada, American manufacturer Cadillac will offer a new feature in its Cadillac CT6 saloon called Super Cruise. Basically, it is a system of assistance to the driving that allows the circulation "without hands" in fast routes.
In this way the General Motors brand is committed to semi-automatic driving, in the style of the well-known Tesla Auto Pilot or the corresponding systems of European manufacturers such as Audi (the new Audi A8 incorporates the latest in the house), Mercedes-Benz or BMW .
What allows this Super Cruise is to circulate on freeways without the driver having to control the direction or the pedals, since the vehicle is able to maintain an indicated speed, to focus automatically in the lane by which it circulates and to draw curves ( in fast, American roads in addition, are not usually very pronounced). It operates at speeds up to 137 km / h (85 mph). It is an autonomous level 2 driving system.
According to Cadillac, the main idea is not that the car is completely autonomous, that it is not, but the driver, while traveling, can perform tasks that require his attention without worry, such as using the navigation system, adjust the system sound or respond to a phone call. Even so, Super Cruise is not able to change lane, overtaking or carry out emergency maneuvers.
The Super Cruise system is based on real-time information collected by ultrasonic sensors, short and long distance radars, video cameras and GPS, but also adds information about the environment captured by laser or LiDAR sensors and captured on a digital map.
According to Cadillac, this high-precision map generated by information collected by LiDAR sensors contains all the highways of the United States and Canada (well-delimited highways with defined access and exit ramps, totaling some 257,000 kilometers) and developed specifically for Super Cruise. Thus, the system works exclusively on dual carriageways (and only in cases where there is no possibility of cross-traffic - in some cases there are crossings on the dual carriageway), and not on rural roads or in urban areas.
In any case, the system requires the attention of the driver. Nothing to take a nap at the wheel or get a movie. In fact, the vehicle has a monitoring system of the driver's own attention to ensure that it is sloped from the road. If you ignore the road for a few seconds, the system deactivates and the car can stop completely if we ignore the indication to resume the steering wheel.
The fundamental device of this system is a small camera located in the steering column that studies the movements of the head and the eyes of the driver, and can determine if it is paying attention or not to the road. It works even in the dark or if you wear sunglasses, because on the steering wheel there are six infrared emitters that "illuminate" the driver.
Those who have tried it say that it is quite simple. Just press the Super Cruise button on the steering wheel, center the car on the lane and let the car take control of itself and let you know by the icon of a green steering wheel in the instrument cluster and a green light on the top of the steering wheel (which is also blue to indicate system paused and red for disconnected).
To perform any maneuver, such as a lane change, the Super Cruise is switched off when the steering wheel is moved or the turn signal is activated, and to re-activate the vehicle, the vehicle must be refocused on the lane and wait for the green indicators to light up and you can release the hands of the steering wheel again.
