An autonomous racing car overtook one other driverless racing car on a Las Vegas racing circuit on Friday: the feat is a primary in the brief historical past of automobiles pushed by algorithms.
On the sting of the oval monitor, the members of the Italian-American workforce PoliMOVE loudly applauded Minerva, the nickname they gave to their car, after it overtook, on a number of events, that of the workforce. South Korean Kaist.
The organizers wished to see the automobiles overtake at the very least 160 km / h. Objective achieved: Minerva was working at 185 km / h when she overtook the South Korean single-seater, which then gave up.
“It's a success,” Paul Mitchell of ESN, co-organizer of the Indy Autonomous Challenge (IAC), informed AFP, even earlier than the race was over. It was held on the sidelines of CES, the annual assembly of the tech business.
The objective of this competitors, in which groups of scholars from all around the world take part, is to advance autonomous driving applied sciences in order that they can work anyplace, together with on highways.
– “Not mechanics” –
At the tip of October, the IAC had deliberate to run the 9 automobiles collectively, however had lastly given up as a result of not all of the groups have been prepared, and had contented themselves with separating them at the most effective time.
“It almost holds the world record for speed of autonomous cars”, boasts Davide Rigamonti, one of many engineers of PoliMOVE, brooding Minerva with a loving look.
In Indianapolis in October, she had climbed the pit straight at round 250 km / h, earlier than spinning into the bend.
In query, no “bug”, however the conjunction of chilly tires and a bent to oversteer (the rear tires slip).
Friday, it's the South Korean car which made laps on itself after having overtaken that of the University of Auburn (Alabama).
“The students who program these cars are not mechanics. Most of them knew nothing about racing,” mentioned Lee Anne Patterson, specialist in single-seater competitions.
“We helped them figure out how to take care of their machine. We taught them about racing,” she says. “For example, when the car is sucked in by another, it gains 8 km / h. How will the autonomy system react?”
– “Milliseconds” –
All the groups obtained the identical car, a Dallara IL-15, a type of small F1, and the identical technological gear with, in the highlight, sensors, cameras, GPS and radars, to permit the automobiles to be on the monitor and between. they.
It is then as much as the scholars to program the software program in order that it makes the best choices.
To be capable to overtake, for instance, “we must foresee how the other car is likely to react, and plan the behavior of our own, according to the physical limits of driving”, underlines Markus Lienkamp, one of many professors of the college of Munich, TUM, who received the October competitors.
“The only parameter to be determined today is the speed. Then, the car does all the maneuvers automatically,” he explains from the tent the place his PhD college students are glued to the management screens.
“It plays out in milliseconds,” says Paul Mitchell. “When a sensor detects another car, it sends a signal to the computer, which sends a signal to the driving system to tell it to adjust speed or to move away … The computer has to make the same decisions. than a human driver, despite the speed “.
The IAC plans to prepare different races on the mannequin of Friday's, pitting two automobiles in opposition to one another, with the hope of reaching a stage ample to in the future launch all of the automobiles collectively.
