Nvidia offers a peek under the hood of its Drive PX 2 platform for self-driving cars

At the Hot Chips conference in Cupertino, California, Nvidia offered more details about its hardware platform for self-driving cars.

It used the conference to unveil Parker, the processor used in the Drive PX 2 platform unveiled at CES earlier this year. Two Parker processors are used in the Drive PX 2, which is already being used by 80 carmakers, Tier 1 suppliers, and university research centers for development of autonomous cars, according to a Nvidia blog post detailing the processor.

The Parker processor is part of a scalable architecture, allowing carmakers to use just one processor as part of a stand-alone system, or upgrade to the full Drive PX 2 setup. The system is capable of hosting multiple functions, including infotainment, digital instrument clusters, and driver assistance functions. Self-driving cars with Parker processors can also receive updates from the cloud, letting engineers deploy tweaks to the algorithms that control them more easily.

The processor uses a new 256-core Pascal GPU, which Nvidia says provides the performance needed to run “advanced deep learning inference algorithms” for self-driving cars, as well as the graphics capabilities for in-vehicle displays such as digital instrument clusters and center-stack screens. Nvidia claims the complete Drive PX 2 system with two Parker processors can run up to 24 trillion deep learning operations per second.

Nvidia already has plans with Volvo to deploy the Drive PX 2 platform in the Swedish carmaker’s autonomous test vehicles. The Nvidia hardware will be used in 100 automated XC90 SUVs, which will be tested on designated public roads in Gothenburg, Sweden, as part of Volvo’s ongoing “Drive Me” autonomous-car development program.

Drive PX 2 will also be used in the autonomous race cars being developed for Roborace. The series is an offshoot of the Formula E race series for electric cars, and will be the first based around autonomous vehicles. Roborace released renderings of a radical robotic race car earlier this year, and has been testing a prototype over the past few months. It hopes to race the finished car in conjunction with the 2016-17 Formula E season.

Autonomous cars confused by San Francisco’s fog
Waymo Jaguar I-Pace electric SUV

Driving in thick fog is a big enough challenge for humans, but it turns out self-driving cars find it pretty tricky, too.

Overwhelmed by dense fog in San Francisco early on Tuesday morning, five of Waymo’s fully driverless vehicles suddenly parked by the side of a residential street in what appeared to be a precautionary measure, the San Francisco Chronicle reported. Another of its cars apparently came to halt in the middle of the street, the news outlet said.

Is Tesla Full Self-Driving worth it?
A Tesla Model S is seen driving to the left.

While many electric cars offer advanced driver assistance tech these days, most of those boil down to a few different technologies working together -- like lane-keeping and adaptive cruise control. Generally, they work quite well. Together, they can essentially allow a car to drive itself on the highway under the right conditions. But companies are also working on the next generation of self-driving cars, and there's been no company more public about this than Tesla, which offers its Full Self-Driving tech.

But while Tesla Full Self-Driving is available to customers, it's far from free. At the time of this writing, Tesla offered Full Self-Driving through a one-time payment of a hefty $15,000, or as a $200-per-month subscription. Neither of those is cheap, and as such you might be wondering whether or not it's worth the money.

Rumors have been swirling around for years regarding Apple’s plans for an electric, self-driving car.

The latest report, which arrived on Tuesday via a usually reliable source, suggests Apple has scaled back its plan for an autonomous car, with some elements yet to be agreed upon.
