Racing autonomous cars through the desert is one thing. Racing a driver-less car up the steep, winding paths of the Rocky Mountains at race speeds is quite another, but that's the goal a team of Stanford graduate students has set for itself, outfitting an Audi TTS named "Shelly" to navigate the Pikes Peak race course wit no one behind the wheel.
Named for French driver Michele Mouton, the first female rally driver to win the Pikes Peak rally in 1985, Shelly's trunk is loaded with computer gadgetry and a $100,000 GPS system that will help direct the piloting software through the course's 12.4-mile, 156-turn ascent to more than 14,000 feet above sea level. With the exception of a couple of exterior fixtures on the roof, Shelley looks and acts like a normal Audi TTS, running on gasoline and handling via standard braking and steering systems. But unlike the average roadster, a software package designed by Stanford's Dynamic Design Lab will execute the actual driving maneuvers, which are designed to closely mimic those of an actual racecar driver.
Other autonomous cars have run the Pikes Peak course before, but those vehicles topped out at around 25 miles per hour; Shelly, whose top speed in the desert is 130 miles per hour, will navigate the course at close to race speeds, a first for a driver-less vehicle.
The students hope Shelley will be the first step toward creating autonomous driving systems that will one day be integrated into all vehicles as a safety measure. "If we can design a car that can autonomously go up Pikes Peak, we can design a car that can take over when a driver falls asleep," Kirstin Talvala, one of the students working on Shelley, told the AFP.
Funded partially by Volkswagen, Shelley will take her first runs to the peak early next year with a driver at the wheel so the software can monitor human reactions to the course, incorporating them into the software. Shelley's first autonomous race to the peak should follow shortly thereafter.
that's pretty freakin cool
Yes, it's cool but...
By using GPS data to control the car on a known route, they are avoiding dealing with the real problem of how to make autonomous vehicles avoid obstacles. Sure they can make the Audi go fast and not drive off the edge, but would this system work if there were other cars on the road? Or rocks or animals or people?
These people have come quite a way from the 'run around like Keystone Kops' from some years back. I wonder if they have to teach each corner separately, at stable speed and under thrust. As I recall, their advances in obstacle avoidance were groundbreaking as well. Consider that almost all accidents come from human error when you look at this.
I saw this in a magazine.
that's pretty cool, next challenge is to learn how to spell ;-) (check out the video at 1:31s "continuous")
