Waabi develops a self-driving vehicle simulator

One of Canada’s autonomous vehicle experts has unveiled a way to help self-driving vehicles develop intuition and experience away from the road.

Raquel Urtasun’s Toronto-based company Waabi revealed on Feb. 9 that it has built a high-fidelity, closed-loop simulator, helping engineers test, assess and ultimately develop a car’s “brain,” so it can learn to safely drive on its own.

The simulator, called Waabi World, acts as a driving school for autonomous vehicles, allowing engineers to advance self-driving technology without potentially dangerous on-road testing and manual tuning.

The simulator uses data and artificial intelligence to build a realistic virtual world that can present both common and “once-in-a-lifetime” scenarios — erratic driving, a car cutting into a lane unexpectedly or merging onto a highway during rush hour — to stress-test autonomous vehicle software.

By using the simulator, the software automatically learns from its mistakes and develops instincts and intuition that would take a fleet of autonomous vehicles years on the road to build up.

“Oftentimes you will see companies say, ‘We drive millions of miles in the real world’ and that’s actually in my opinion a negative, because they require all the driving in order to really understand or see when the system fails,” said Urtasun, who served as the chief scientist for Uber’s autonomous vehicle efforts until she struck out on her own last year.

Using Waabi’s simulator, which was created in just six months, doesn’t eliminate the need for a car to drive on a physical road during development, but it reduces driving and development time, slashes costs and in some cases, cuts the number of vehicles companies need for testing.

The small fleet Waabi is building will still hit the road in tandem with its use of the simulator to test how well its virtual training helps the vehicle learn compared with real-world experience.

Urtasun does not plan to license Waabi World to competitors, but imagines the simulator will be helpful for regulators that will eventually have to assess self-driving vehicles and find ways to safely and quickly evaluate the car’s performance.

For now, Urtasun is focused on advancing her fleet.

The company will work first on the logistics and long-haul trucking industries because of the extreme driver shortages and surging demand they are seeing, but Waabi’s technology could easily be applied elsewhere.

Dozens of companies ranging from automakers Ford, Audi and Tesla to tech brands such as Apple, Microsoft and Google have joined the race to develop autonomous vehicles.

Uber was a key player until decided to sell its six-year-old self-driving venture — called the Advanced Technologies Group — to Silicon Valley startup Aurora.
