GM’s Onstar division has long raised privacy concerns among the professionally paranoid, but now it’s putting all that observational power into the hands of consumers, with a pilot program called “Family Link.”  Described in GM’s presser as “a new optional service that will explore ways subscribers can stay connected to their loved ones,” the service includes

  • Vehicle Locate: The subscriber can log on to the Family Link website to view a map with the vehicle’s exact location at any time.
  • Vehicle Location Alert: Subscribers can set up email or text message notifications to let them know the location of their loved one’s vehicle. They can choose the day, time and frequency of the alerts.

But that’s not all: if the pilot proves that consumers are willing to pay for the right to surveil their loved ones,

Future considerations for the pilot include Speed Alert, Boundary Alert and Arrival/Departure Alert.

Forget Big Brother… with this system, you can be Big Daddy, in the center of your own little family-sized panopticon. From making sure the kids stay out of trouble (“Say, son, what were you doing in downtown Detroit last night?”) to checking up on your loving spouse (“Honey, why did you say you were going to the gym, when you just parked for an hour at the Slee-Zee Snooze Motel?”), it’s how today’s on-the-go families foster an atmosphere of suspicion and mistrust. Because why let the government have all the voyeuristic fun?

Former TVR owner Peter Wheeler used to explain the lack of airbags in his firm’s high-powered sportscars by arguing drivers would be safer if he installed a metal spike in the middle of each steering wheel. That was back in the late 1990s and early 2000s… since then, the rise of adaptive cruise control, “attention assist” systems, collision-sensing brake pre-loading and more have only made his critique all the more provocative. And, according to research cited in a Wired Magazine report, Wheeler’s philosophy seems to have a strong basis in science.

“The point the automakers are making, which is true, is that they go to extreme lengths to make these systems work and extremely reliable,” [Stanford University’s Clifford] Nass said. “The reliability on these systems is very high. If you have automatic cruise control, it’s not extremely often you have to jump into the fray.”

Therein lies the problem. We come to count on our cars to keep us out of trouble, even in situations where the technology isn’t designed to.

“Road hazards other than the car in front of you are so rare, especially on the highway where these adaptive cruise control systems would be in play, that they would, over time, encourage a complacency that undermines safety,” said Erik Blaser, a psychology professor at the University of Massachusetts, Boston, who studies vision and perception. “You stop paying attention to the driving.”

Though these “semiautonomous” systems are sold as safety equipment, researchers argue that they create a sense of reliance that actually makes drivers less safe (unlike “secret” safety systems like stability control and ABS, which operate consistently without the driver’s knowledge). And, somewhat counterintuitively, these researchers argue that the rise of semiautonomous driver aids actually increases the need for life-long driver eduation.

Between Nissan’s Leaf racer and a new EV-only racing cup, electric auto racing has been coming along in recent months, although significant challenges remain. For one thing, batteries are still extremely heavy, and for another, they take a long time to recharge. Finally, thermal management issues conspire with both of these battery challenges to force EV races to be quite short. And in search of a solution, one team that’s entered into the EV Cup is looking to the original EV racers for inspiration: slot cars. Rather than getting hot and heavy with big batteries, figures Drayson Racing Technologies, why not charge the car as it’s racing at speeds upwards of 200 MPH? Luckily HaloIPT has come aboard the project, bringing its eponymous wireless Inductive Power Transfer technology to bear in order to create life-sized, wireless, slot-free slot cars.

In addition to the recent tales (and sitcom gags) of GPS units leading hapless drivers into bodies of water, we have a new twist on the theme: GPS units leading hapless drivers astray in Death Valley. NPR reports

After a long day, [Donna] Cooper and her family asked “Nell,” the GPS, for the shortest route back to their home.

“Please proceed to the highlighted route,” Nell said.

But what came next did not compute. The GPS told them to go 550 feet, then turn right, Cooper says.

“Well, at 550 feet it was like a little path, and then it was like, go a quarter of a mile and turn left. There was nothing there. She had me running in circles for hours and hours and hours,” she says.

A park ranger explains that this happens “a couple times a year now,” including one incident two years ago in which a mother and her son were lost on an abandoned mining road for five days and the boy died. Rangers are now working with GPS firms to update their data on small and closed-down roads, but say no amount of work will ever replace common sense when it comes to navigating desert roads. Speaking of which, what happened to Cooper’s family?

Research into environmentally sensitive ways of running a car, AKA “green patents” have been in the news lately and it’s been good news for GM’s image. The Detroit automakers in general are not seen as technology leaders, particularly in terms of alternative energy. Bob Lutz saw the Chevy Volt as a way of changing that perception, taking away some green luster from Toyota. Since there is usually considerable time between a patent’s filing and its granting, patents granted in the last 2 or 3 years are a good reflection of what a company has been doing for the past 4 or 5 years, and there’s evidence that Lutz’s strategy was not just a PR job but also a reflection of a very large amount of research and development at the automaker. Cleantech Group, of the Heslin Rothenberg Farley & Mesiti intellectual property law firm, publishes the Clean Energy Patent Growth Index. The CEPGI tracks the granting of U.S. patents for solar, wind, hybrid/electric vehicles, fuel cells, hydroelectric, tidal/wave, geothermal, biomass/biofuels and other clean renewable energy. The law firm publishes the CEPGI quarterly and then tabulates the annual results.

Over the last several years, Toyota has fought off suits by a firm called Paice, which claimed to own patents on technology used in Toyota’s hybrid drivetrains. Toyota settled that dispute a year ago, but now Bloomberg reports that another firm is going after Toyota’s hybrid Intellectual Property (IP). According to the report

Efficient Drivetrains Inc., based in Palo Alto, California, has an exclusive license from the University of California for use of the technology, including the way electricity is drawn from a battery to power an electric motor and an internal combustion engine, according to a July 20 federal court complaint filed by Toyota in San Jose… The five patents at issue also include technology, invented by EDI co-founder Andy Frank, on ways to control the power output of an internal combustion engine and a method to draw electricity to operate the electric motor and the internal combustion engine, together or separately depending on driving conditions

In my review of the VW Golf blue-e-motion on Tuesday, I noted that “the holy grail of EV development is a multi-speed transmission,” but that nobody has been able to build one that can reliably handle the 100% torque at zero RPM characteristics of an electric drivetrain. Tesla tried two different multi-speed transmissions (from X-Trac and Magna), before giving up and going with the single-speed setup that every production EV now uses. Nobody has even talked about a multi-gear EV since… until now. With Fisker’s Karma about to go to market, CEO Henrik Fisker tells Autocar that his firm is developing a multi-speed EV gearbox, and that it would improve performance in EVs like the Karma, saying

With the torque at the wheels increased by the use of a gearbox, Veyron levels of performance should be possible.

We’re as excited as anyone else by the idea of an EV with shiftable gears, but this sounds more like Fisker trying to drum up some hype for the Karma launch. After all, the Karma launches to 60 MPH in a leisurely 7.9 seconds in “stealth” (EV) mode and 5.9 seconds in “sport” mode with gas power to up the wattage… a far cry from Veyron performance. As C&D puts it:

The Karma’s initial surge is sufficiently potent to avoid damnation as a slug. But the physics conspire against it keeping pace with other $100K sports sedans.

Lugging over 4,000 lbs is certainly easier with a multi-gear transmission, but given the reliability challenge, we’d be more likely to trust an EV transmission from a reliable supplier rather than a boutique luxury PHEV maker. And until Fisker can back up the Veyron reference with some hard evidence, we’re filing this one under “intriguing but unlikely.” Still, it’s exciting to know that this technical challenge is still out there, unconquered by major manufacturer or feisty startup… in a world where cars are becoming increasingly mundane, the multi-gear EV transmission challenge is a throwback to the golden years of automotive development.

As automakers face slowly diminishing returns in their attempts to make internal combustion engines more efficient (while facing huge challenges in electric, hydrogen and other alt-fuel drivetrains), they are looking ever more closely at alternative materials to improve efficiency (and, to a lesser extent, driving pleasure) through weight-savings. Perhaps the biggest emerging trend in this area, especially at the higher end of the market, is in the use of carbon fiber, which is being actively pursued by automakers like BMWToyota, Lamborghini and Daimler. But, as WardsAuto points out, there’s another material that’s trying to earn a place in the lightweight cars of tomorrow: polycarbonate plastics.

Polycarbonate windows weigh half as much as glass, and because they are made with injection molding they can come in shapes that can’t be imagined with glass.

However, the material is more expensive. To get auto makers to convert, Sabic and its main material competitor, Bayer MaterialScience, have to sell the idea of integrating other parts into the plastic mold that makes the window.

For example, says Umamaheswara, “on a liftgate, a lot of features can be integrated, and if the manufacturer is short of room in the factory, it can be delivered as a module.”

A modular liftgate could include the window, cladding for the D-pillar, a roof spoiler, the high-mounted rear brake light, a rear wiper foot, handles and logos. When all those processing costs are included, he says, polycarbonate is competitive with glass and metal.

TTAC has long seen stop-start systems (which turn off the engine at idle) as one of the many common-sense technologies that will continue to improve internal combustion engine efficiency at a relatively low cost. Outside of these digital pages, though, the systems have taken longer to gain awareness in the United States, resulting in the lagging adoption rate pictured in the chart above. Up to this point, we’ve assumed that this can largely be blamed on the EPA test’s unwillingness to acknowledge the urban-driving advantages of stop-start systems, pointing to Mazda’s protests on the matter as evidence that government intransigence was keeping the technology out of the market. But recently Mazda has announced that all of its vehicles will get stop-start as standard by 2015, and Ford has said that it will begin offering the technology on “some” four-cylinder models for the North American 2012 model-year… and the rest of Detroit isn’t far behind. So what’s the deal? The EPA hasn’t changed its test… why are stop-start systems finally starting to trickle over?

Thanks to new research obtained by TTAC from the cleantech investment fund Pacific Crest, we now have a better understanding of stop-start technology, and why we’re actually glad it’s taking so long for the systems to get here.

Smell that? It’s the gathering scent of a new industry trend towards natural gas. Honda’s expanded its pioneering Civic GX to 50 states, Sergio Marchionne wants to replicate his Italian CNG success at Chrysler (eventually), and now GM is jumping on the bandwagon while it’s still relatively uncrowded. The Winnepeg Free Press reports that GM has signed a development deal with Vancouver, B.C.-based Westport Innovations which could see a prototype light-duty natural gas-powered engine completed “within 18 months” if preliminary study proves promising. A Westport spokesman boasts

If both parties agree to move ahead with commercialization this would be one of the first pure OEM [natural gas-powered] products

You know, except the Civic GX which has been prowling American streets since 1998. Still, with Chrysler targeting CNG commercialization no earlier than 2017, GM could have a strong head-start on a fuel technology that promises to be a viable and promising gasoline alternative, especially if the NatGas Bill [PDF] passes, expanding $7,500 plug-in tax credits to natural gas vehicles. And GM’s got a strong partner in Westport, which has heavy-duty commercial deals with Cummins and Caterpillar. With Nissan all-in on EVs and years ahead of the competition in terms of global EV production capacity, look for other competitors to hedge their alt-energy bets… and natural gas is rapidly becoming the most popular alternative.

TTAC’s man-about-the-junkyard Murilee Martin has made the bold claim that we live in the golden age of cheap superchargers, but when it comes to new cars, we may be entering another “golden age” for superchargers as well. Eaton’s Ken Davis tells Automotive News [sub] that his firm is looking at doubling its supercharger sales as the technology comes into its own as a fuel-saving measure. Though turbochargers have received the lions share of attention as the industry moves towards downsized, forced-induction engines, Davis argues that supercharger have their own role to play in the effort, specifically when it comes to “downspeeding” engines to produce better power at lower RPM. He adds

Audi is our largest supercharger customer, and we are on a couple of platforms with Nissan… Nissan will bring their supercharged vehicles here. We’ll be on Audi and Volkswagen platforms, too. We are starting to get some attention.

Having seen its RX-8 banned from Europe for flunking emissions tests, Mazda may be going to extreme lengths to improve the efficiency of its next-gen rotary engine (codenamed 16x) which has been in development since 2007. Autocar reports

The 16X’s capacity has been raised from 1304cc to 1600cc, and it is also physically smaller and partly built from aluminium. The changes are designed to improve two of the biggest issues with rotary engine performance: fuel economy and torque delivery.

The Mazda source said the new engine “needed a smaller hole on the wall [of the combustion chamber]” as a result of eliminating the space-hungry normal spark plug. He also admitted to Autocar that the use of laser ignition “was absolutely possible”.

Recent advances in Japan have created high-power lasers made from ceramics that measure just 9mm in diameter and 11mm in length, easily small enough to fit into a car engine.

Not only would laser ignition allow the 16x to burn leaner, it would also allow more precise control of ignition points and timing. More importantly, it would cement the Wankel rotary’s status as the least-necessary, most overly-complex and thoroughly awesome engine ever created. And they say emissions standards always make cars less interesting…

Google’s autonomous cars have already shown how close vehicles are to driving themselves in day-to-day traffic, but there’s still one uncontrollable, unpredictable, and often-irrational variable that autonomous cars still struggle to cope with: you, me and all the other haphazardly-programmed human beings on the road. And though predicting human behavior might be one of the most difficult tasks for a human-programmed computer, researchers at MIT are already digging into the challenge. Using model cars (one autonomous, one human-controlled) on overlapping tracks, 97 out of 100 laps avoided collision. But not all of those laps fell into the near-collision “capture set”… which, as it turns out, is what makes the human threat to autonomous cars so challenging.

According to [MIT Mechanical Engineering Professor Domitilla] Del Vecchio, a common challenge for ITS developers is designing a system that is safe without being overly conservative. It’s tempting to treat every vehicle on the road as an “agent that’s playing against you,” she says, and construct hypersensitive systems that consistently react to worst-case scenarios. But with this approach, Del Vecchio says, “you get a system that gives you warnings even when you don’t feel them as necessary. Then you would say, ‘Oh, this warning system doesn’t work,’ and you would neglect it all the time.”

More people feel that the task of driving belongs to the driver, and do you really want to sort of hand over your safety to a machine? It’s possible the technology might one day be widely deployed. I just don’t think we’re anywhere close to that right now

NHTSA Administrator David Strickland came away from his first run-in with Google’s autonomous cars in a less-than-entirely optimistic mood [via the DetN]. You might think that Strickland, who is a central figure in Transportation Secretary Ray LaHood’s “War on Distraction,” would appreciate a driver that has no need for Twitter, Facebook or the other increasingly-common in-car distractions. Instead, he took his position to its remarkably solid core: that individuals need to think more, not less, about their responsibilities as drivers. It’s actually a fantastic message, especially given that he wasn’t kidding about the “technology isn’t ready” part, telling the DetN

There’s near misses. It’s not fool-proof. There’s a lot of work to go, [but] it’s a great piece of technology.”

Since Nissan’s PR and communication folks are probably having a busy morning anyway, we thought we’d bring this video to their attention. According to this apparently quite tech-savvy Leaf owner, the Leaf’s CarWings system will automatically send your location data to any third-party RSS feed you sign up for. As he puts it in the video

“There’s a lot of personal data there. I’m not sure if you really want Fox News to know exactly where you’re at, how fast you’re driving, that kind of thing… when you read those RSS feeds in your car, you might want to think twice about hitting that button”

Why would signing up for an RSS feed require that constantly-updated locational data be sent to the RSS provider? The video’s maker assumes the data is for “CarWings internal use” and yet he shows that it gets sent to third parties. We know GM monitors Chevy Volt user data anonymously through Onstar, but one assumes that this kind of data is fairly well protected from third parties. In the case of the Leaf, that may not be the case. We’d sure like to know if this is true, and why…

[UPDATE: Nissan tells us: “Owners have to opt in or agree to share their data every time they sign in.  If they don’t, then they pass on the benefit as well.  They will however, lose any remote control or data logging capability but the choice is in the hand of the driver every time.”]
