Nvidia Unveils New Tegra X1 Chip

Chipmaker Nvidia debuted a new processor aimed at powering high-end graphics on car dashboards as well as sophisticated auto-pilot systems.

At an event in Las Vegas ahead of the Consumer Electronics Show, Nvidia Chief Executive Jen-Hsun Huang said the Tegra X1 chip would provide enough computing horsepower for automobiles with displays built into mirrors, dashboard, navigation systems and passenger seating.

“The future car is going to have an enormous amount of computational ability,” Huang said. “We imagine the number of displays in your car will grow very rapidly.”

The Tegra X1 has twice the performance of its predecessor, the Tegra K1, and will come out in early 2015, Nvidia said.

An upcoming platform combining two of the X1 chips can process data collected from up to 12 high-definition cameras monitoring traffic, blind spots and other safety conditions in driver assistance systems, Huang said.

Combined with next-generation software, the chips can help detect and read road signs, recognize pedestrians and detect braking vehicles, he said.

Santa Clara, California-based Nvidia in recent years has been expanding beyond its core business of designing high-end graphics chips for personal computers.

After struggling to compete against larger chipmakers like Qualcomm in smartphones and tablets, Nvidia is now increasing its focus on using its Tegra mobile chips in cars and is already supplying companies including Audi, BMW and Tesla.

Tesla Updates Charging Software

Tesla Motors Inc is making changes to prevent overheating of its charging systems, including giving customers upgraded wall adapters and providing charging-software upgrades, the electric-car company said on Friday.

The moves come after a November garage fire involving a Model S in Irvine, California, which the Orange County Fire Authority said may have been caused by a Tesla charging system or by a connection at the electricity panel on the wall of the garage.

At the time, Tesla disagreed with the fire officials’ findings, denying that the charging electronics were related to the fire. A Tesla spokeswoman did not immediately respond to a question on Friday about whether the upgrades were related to the Irvine fire.

In a Friday press release, Tesla said that its goal was to prevent excessive heating of the adapters used to charge its cars. A variety of factors ranging from corrosion to inappropriate wiring of electrical outlets can cause overheating, the company said.

A December tweak to its charging software tackles the issue through reducing charging by 25 percent if the charging system detects fluctuations in power entering the vehicle, Tesla said.

“Tesla believes that this software update fully addresses any potential risks,” the release said. But as a precaution, it said it would make available an improved wall adapter with a thermal fuse for affected customers, staring in a few weeks.

Separately, three road fires in Model S sedans caused Tesla’s stock to fall sharply in October.

The fires occurred in Washington state, Tennessee and Mexico. In the U.S. incidents, Model S sedans caught fire after running over road debris. In Mexico, a Model S caught fire after striking a concrete wall.

On Friday, Tesla’s stock fell 1.23 percent to $145.72, up from levels under $120 in late November but down from its high of $194.50 in late September.

AT&T Gets GM

AT&T Monday said it will provide LTE wireless services to most General Motors automobiles starting in 2014 in the U.S. and Canada.

A multi-year agreement between AT&T and GM subsidiary OnStar calls for vehicles to continue getting OnStar’s safety and security services while adding information and entertainment services for backseat drivers, AT&T said.

Millions of vehicles will be affected, as AT&T rolls out LTE to reach 300 million people in the U.S. by the end of 2014.

The AT&T-GM announcement is part of an explosion in the number of devices connected to the Internet, many of them wirelessly, in what some have termed the “Internet of Things.”

“The is a big announcement for connected devices,” Glenn Lurie, president of emerging enterprises and partnerships at AT&T, said in an interview at Mobile World Congress here.
