LAS VEGAS—In its keynote showcase at CES, Mercedes-Benz emphasized advances in telematics, which is seemingly turning its automobiles—like those of its competitors—into rolling social-media platforms. However, off the show floor, Daimler researchers interviewed by EE Times told a potentially more impactful story of research which could ultimately deliver serious weight reductions and range boosts for electric vehicles.
The keynote speech was given Tuesday (Jan. 10) by Dieter Zetsche, chairman of Daimler AG and head of Mercedes-Benz. Zetsche became famous in the U.S. a decade ago as "Dr. Z," the star of television commercials for Chrysler Corp., which Daimler owned at the time.
At CES, Zetsche turned his Teutonic charisma to the task of marketing what he called the next level of auto mobility. That would be Daimler's telematics system, called mbrace2, which is making its first appearance in Mercedes' new SL, and will soon become standard on all its U.S. models.
Billed as cloud based, mbrace2 uses Daimler's Vehicle Backend Server to continuously stream navigation information to the car, and to enable connectivity to social media sites such as Facebook. In the other direction, it'll send real-time automotive diagnostics back to the dealer.
On a marketing basis, it's billed as a "digital lifestyle" solution which can function as a "personal concierge." That will allow parents to track what their kids are doing with the car, search on Google, and perform other common Internet-era functions.
However, beyond such low-hanging consumer fruit, Zetsche alluded to more serious applications which will be possible via the continued uptick in embedded automotive smarts. "We're working on a new generation of vehicles that serve as digital companions," he says. Proactively offering consumers entertainment is a big part of that, but so are weather and road-condition advisories for drivers' planned trips.

Lest consumers construe modern vehicles as electronics platforms with engines and transmissions thrown in as after thoughts, Zetsche responds with the view that telematics will lead to improved safety. "We use the Web to manage huge amounts of data traffic," he says, "So why not use it also to manage huge amounts of road traffic?"
Such data sifting would include analysis of GPS data from smartphones to identify traffic hot spots and thus shunt drivers around delays. It could also encompass collision avoidance technology. "It's still key to make the car as safe as possible, so we are pursuing the vision of an accident-free car," Zetsche says.
While in-car electronics dominated Mercedes' public message, engineers involved with the company's research and development operation told EE Times that there's ample work going on behind the scenes to advance both safety and alternative power-train technologies.
Carbon-fiber composites, which are playing a major role in aerospace due to their heavy use in Boeing's new Dreamliner, are currently too expensive for extensive automotive use. (High-end electric car maker Fisker uses composites in its vehicles.) A Mercedes researcher said he believes the accelerating use of composites will result in reduced cost of manufacturing, and that carbon fiber will begin permeating the automotive sector.
It'll be a long time, if ever, before all-composite cars are common. However, even limited use of composites can result in weight reduction. The latter is important because lighter cars can run longer. For plug-in electrics, that's significant because "range anxiety" has been the biggest consumer stumbling block.
Looming even larger has been the lack of Moore's Law-like advances in battery technology. Storage capacities and energy densities of electric car batteries have advanced little in the past decade. Lithium-ion remains at the cutting, even as its drain time and range remains stagnant. Contrary to commonplace thinking that batteries are likely to remain forever stalled, the Mercedes researcher believes advances will ultimately come from experiments with new chemical formulations.
I think that progress with batteries in electric cars are far more important than turning cars into social media platforms. Car purists and environmentalists would rather see more mileage come out of their electric cars than being able to send a Tweet on the move. Here's to hoping that Mercedes get their priorities right.

I am not sure if Mercedes Benz coming up with the mbrace2 is really just a gimmick to divert attention away from the fact that it has not made significant improves to the existing cars in terms of engine, safety and efficiency. Having the ability to connect to Facebook and use Google seems like trivial affairs when compared to other serious advancements that can be made, like better braking systems, and more efficient engines.

Glad to hear that Mercedes continues focusing on the efficiency of their automobiles in addition to making them more technologically advanced. While a car that can update your Facebook status is certainly pretty cool, a vehicle that uses carbon fiber reinforced plastics to reduce weight while maintaining safety is a win for both consumers and the environment. Thanks for the great write-up, Alexander Wolfe!

Intense competition and interest in plug-in (PHEV) and pure electric (BEV) cars are driving innovation in battery designs. We're in a very dynamic portion of the development cycle with battery chemistry, nanotechnology, air and fluid cooling systems all changing in an effort to improve safety and energy density. Like solar cell R&D, every day seems to bring another breathless report of a breakthrough technology. It will be interesting to see what designs settle out as the best technologies.
Mercedes foresees collision avoidance technology,weight reductions and range boosts for electric vehicles,real-time automotive diagnostics back to the dealer, allow parents to track what their kids are doing with the car ,road-condition advisories for drivers' planned trips,vision of an accident-free car, number of new features to welcome. Also they said that It will take a long time, if ever, before all-composite cars are common.
Pursuing "an accident-free car" is a noble cause, but accidents will happen and reliable speech recognition in the noisy car atmosphere is a priority for telematics. Drivers should not be satisfied with "digital concierges", but with "intelligent concierges" who listen and react instantaneously to avert accidents. But then some accidents are beyond technology to react. Ask anyone hit by a deer on route 20 in upstate NY.

David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
