Why CERN’s work on Volvo’s autonomous cars won’t matter much

The world-renowned European Organization for Nuclear Research (better known as CERN) is working to develop “fast machine learning” for self-driving cars, according to CNBC. CERN has some of the best research facilities in the world, and has made breakthroughs in physics. But it’s unclear if CERN’s new research project will get autonomous cars into production any faster.

CERN is best known for the Large Hadron Collider, the world’s largest particle accelerator. The organization’s research produces vast amounts of data, so scientists have developed machine learning software with a focus on fast decision making, in order to sift through it. Zenuity — a joint venture between Volvo Cars and Swedish firm Veoneer — hopes to use that software to speed up decision making in self-driving cars.

In a statement, Zenuity said CERN’s Field-Programmable Gate Arrays (FPGAs) could “execute complex decision-taking algorithms in microseconds.” The idea is to use FGPAs to help autonomous cars make decisions more quickly. As any human driver knows, a quick decision is often needed to avoid a crash. But that’s only one piece of the puzzle.

Fast computing could allow self-driving cars to make decisions at the same speed as humans, but the systems that control these cars also need to have the knowledge to make the right decision. Companies developing self-driving cars are conducting real-world testing and running simulations to expose autonomous-driving systems to as many potential scenarios as possible. But the unpredictability of real-world driving conditions means covering everything is a monumental task.

Autonomous cars also need the right information to make an informed decision. The cars rely on an array of sensors — usually composed of cameras, radar, and lidar — to “see” their environment, and complex computer-vision software to interpret camera images. Creating a sensor setup that works reliably in all conditions, is durable enough for everyday use, and is cheap enough for mass production, is another major hurdle for autonomous cars.

Despite the technical challenges, many companies remain committed to self-driving cars. Volvo plans to put an autonomous car into production in the early 2020s. The automaker is also working with Uber on autonomous-driving tech. Volvo previously provided XC90 SUVs to Uber, one of which struck and killed a pedestrian in March 2018. Volvo has nonetheless renewed its partnership with Uber, and hopes to get a new generation of XC90 test vehicles on the road in 2020.

A weird thing just happened with a fleet of autonomous cars
A passenger getting into a Cruise robotaxi.

In what must be one of the weirder stories linked to the development of autonomous vehicles, a fleet of Cruise self-driving cars gathered together at an intersection in San Francisco earlier this week, parked up, and blocked traffic for several hours. And to be clear: No, they weren't supposed to do that.

Some observers may have thought they were witnessing the start of the robot uprising, but the real reason for the mishap was more prosaic: An issue with the platform's software.

Officers confused as they pull over an empty self-driving car

In what appears to be the first incident of its kind, police officers recently pulled over a self-driving car with no one inside it.

The incident, which took place on a street in San Francisco earlier this month, was caught on video by a passing pedestrian. It shows several traffic cops pondering about how to handle the incident after stopping the vehicle for failing to have its front lights on while driving at night.
