It turns out that not all advanced “helper” of the driver, like adaptive cruise control or hold in the band of the useful and reliable. Even in the expensive premium they can avoid critical mistakes.
To such conclusion the American automobile Association (American Automobile Association, AAA), which conducted a series of tests with the BMW X7, the Cadillac CT6, the Ford Edge, Kia and Subaru Outback Telluride, released in 2019 and 2020.
All cars were equipped with some form of semi-Autonomous driving technique, like Super Cruise in Cadillac or Highway Driving Assist Kia in Telluride. Extensive testing showed that the test 6437 kilometers they made serious mistakes over the 12.9 km (average).
The worst was working the help system while keeping traffic lanes: it accounted for 73% of incidents. The experts noted that the effectiveness of its functioning depends significantly on the quality and brightness of the markings (which is logical). If the road was recently repaired and the markings more contrasted against the background of asphalt, then the electronics is not difficult to navigate properly. But even in the wealthy United States, the share of such highway is very small. In the end, the result left much to be desired. Plus, the withholding system in the lane at times too close failed vehicle to other vehicles or fences.
Dissatisfaction of analysts called and recognition of obstacles. For example, in a simulated situation where a vehicle is on the side of a roadway, the top of the crossover BMW X7, made the collision in two cases out of three. Once he never saw obstacles, and the other recognized him too late, having to slow down from 48.3 km/h only to 40.4 km/h. X7 Only once did everything correctly and the advance stopped.
Kia Telluride demolished simulated vehicle all three times, though, and tried each time to stop.
The Subaru Outback only once collided, besides slowing to 23.1 km/h.
In the end, the test machine allowed clashes in 66% of cases. And this despite the fact that they were moving at a modest speed of 48.3 km/h.
But there was a place for praise. All cars worked well the adaptive cruise control in traffic. He easily led machine for going ahead of the vehicle, time slowing down and speeding up.
However, in the current form of the driver assistance system often pose more of a danger. First, the owner of “smart” machines can get too comfortable, relying on modern electronics. Second, manufacturers diskreditiert itself, advertising the capabilities of their systems.
