Google to unveil Auto Link at Google I/O — next stop, self-driving cars

Google will unveil one small portion of its push to smarten the ordinary auto at the Google I/O conference this week, tech partner Nvidia said on Tuesday.

At the California conference, where the company is expected to discuss everything from smartwatches to “quantum paper,” the company will show off Google Auto Link, an automotive head unit that connects to smartphones running the Android operating system is and a clear rival to Apple’s CarPlay system.

Google’s system will be controlled via the steering wheel and used largely for infotainment at present, including consumer applications such as music and mapping. But the 192-core, “supercomputing” power of the Tegra chips that power Nvidia’s larger car platform — and is likely to be in Google’s Auto Link — will ultimately be able to do much more. Nvidia plan a much tighter integration to the automobile, through an embedded system that’s capable of customizable, photorealistic digital instrument panels and advanced driver assistance – meaning steering, parallel parking, safety systems that avoid collisions, and more, just like the self-driving cars that Google has shown off.

This won’t be Google’s self-driving tech, however. 

“Google’s cheating,” joked Daniel Shapiro, senior director of automotive for Nvidia, at a New York City event.

The Tegra platform can run multiple OSes simultaneously, dedicating only some of its processing cores to analyzing real-time video to avoid collisions and steer, for example.

Google’s cars navigate by comparing laser scans of the surrounding topography to pre-loaded maps of a particular area that have already been scanned in meticulous detail. In other words, if Google hasn’t already deeply scanned and recorded the area, its self-driving cars can’t drive themselves in that area.

The Tegra platform, on the other hand, analyzes in real-time video of the surrounding environment in order to avoid collisions and steer, for example. It’s simply a different approach to the problem — both are computational nightmares. And because it’s able to run multiple operating systems simultaneously, it can dedicate only some of its processing cores to a real-time platform such as QNX, and at the same time dedicate other cores to an OS such as Android to power voice recognition and YouTube or Netflix for the kids in the back seat.

“Nvidia being used for safety systems – that’s the beginning of a big industry shift,” explained Roger Lanctot, associate director of the Global Automotive Practices for research firm Strategy Analytics.

“Google wants to be in the car but they want to control those implementations. They don’t want forks of Android, like Amazon’s Fire OS,” he told Digital Trends.

Regardless of how self-steering cars come about, the technology remains a long way off. There are approximately 5 million cars on the road with Nvidia chips in them, Shapiro said. None of them are currently being used for safety and driver assistance features. There will be over 25 million more cars in the next few years, from names such as BMW, VW, Porsche, Tesla and Audi. Of those cars, only a small percent will be using the chips for some form of autonomous navigation, he said.

Car companies have instead been opting for small steps towards automation, including such features as parallel parking assistance and cars that park themselves.

Audi has been a key partner for Nvidia to date. The company said other European models from partners incorporating its technology are likely to be unveiled at the Paris Auto Show this fall. Production units are expected by the end of the year, though they likely won’t make U.S. shores in that time.

Auto Link, as the technology has been called in several reports, is the first product of the OAA, or Open Automotive Alliance, a partnership between Google and Nvidia and several automotive companies including GM and Audi to create a standardized, easily expanded platform for automotive technology.

Nvidia would not confirm when cars with embedded versions of Android will appear.

“The expectation is that the next step for the OAA will be an embedded version of Android used as the operating system for infotainment systems,” a spokesman said.

Google I/O: There are big changes coming to Play Store reviews

Google Play Store customers -- some 2.5 billion souls in more than 190 countries -- have a new app and game review calibration to look forward to in August, according to Kobi Glick, product lead of Google Play. Speaking at a deep-dive session at Google’s annual I/O developer conference, the Play team departed from the usual code-speak to reveal an updated approach to app reviews designed to focus on more recent, and thus more relevant, reviews that app and game developers believe will better serve the public and provide a more accurate reflection of their apps.

“Many of you told us that you want a rating that reflects a more current version of your app, not what it was years ago -- and we agree,” Glick said. “So instead of a lifetime cumulative value, your Google Play Store rating will be recalculated to give more weight to your most recent ratings.” Users won’t see the updated rating in the Google Play Store until August, Glick said.

Google I/O: Android Q aims to bring app permissions firmly under control
google io 2019 android q permissions and security privacy

Google is capitalizing on Google I/O 2019 to detail how it intends to make Android app permissions and security better in Android Q, which will, in turn, make your smartphone a safer, more secure place for your data.

The biggest change to Android Q's permissions is the addition of a more targeted system. At the moment, granting a permission in Android is an analog process -- you either grant an app storage permission or you don't. While that makes everything nice and simple, it means that there are no limits on the app where timing is concerned.

Google I/O 2019: Here’s everything we saw, from Android Q to midrange Pixels
Google I/O 2019

What a beginning. The Google I/O 2019 keynote is over, but it felt like a tour de force from the beginning to the end. While some of our predictions didn't come true -- will we never have a Pixel Watch? -- the most anticipated rumors did come true, and that means we met some desirable new hardware, including the midrange Pixel 3a and the Nest Hub Max. Android Q was also in attendance, as expected, and it's made us even more excited for the future of mobile technology.

But there were plenty of things we didn't see coming, including Google's focus on creating mobile tech that everyone can engage with, and the shrinking down of existing tools so they can be made more easily available to everyone. Here's everything we saw at Google I/O 2019.
