Toyota takes self-driving step with patent for eyelid detection device

With the rise of smartphones and more advanced auto infotainment systems, combatting distracted driving is a growing concern. One day, fully autonomous vehicles could end the problem, but that solution is still at best years away for consumers. Until then, automakers are working to make the tech safer, and one way to do that is monitoring drivers' eyes to make sure they're paying attention. With a recent patent, Toyota thinks it can make the tracking work even better. In Japanese brand's patented solution, a camera constantly monitors the driver's upper and lower eyelids and uses the data to calculate how open the eyes are. The company admits systems like this already exist elsewhere, but they can sometimes return false results by detecting redeye instead of the location of a person's actual eyeball. To fix this, the automaker adds a further step to search for redeye. If it occurs where skin is already assumed to be, then the system can go back to tracking the accurate location of the eye. Toyota doesn't specify how it might use this technology, but more accurate data would always be useful. The company wouldn't be the first automaker to work on implementing eye detection, either. For example, General Motors has a pilot program using it to monitor distraction, and Jaguar Land Rover watches a driver's peepers to create the 3d image for its Virtual Windscreen. Related Video:

Solid-state batteries: Why Toyota's plans could be a game-changer for EVs

Word out of Japan today is that Toyota is working on launching a new solid-state battery for electric vehicles that will put it solidly in the EV game by 2022. Which leads to a simple question: What is a solid-state battery, and why does it matter? Back in February, John Goodenough observed, "Cost, safety, energy density, rates of charge and discharge and cycle life are critical for battery-driven cars to be more widely adopted." And risking a bad pun on his surname, he seemed to be implying that all of those characteristics weren't currently good enough in autos using lithium-ion batteries. This comment is relevant because Goodenough, professor at the Cockrell School of Engineering at the University of Texas at Austin - it so happens, he turns 95 today - is the co-inventor of the lithium-ion battery, the type of battery that is pretty much the mainstay of current electric vehicles. And he and a research fellow at U of T were announcing they'd developed a solid-state battery, one that has improved energy density (which means a car so equipped can drive further) and can be recharged more quickly and more often (a.k.a., "long cycle life") than a lithium-ion battery. (Did you ever notice that with time your iPhone keeps less of a charge than it did back when it was shiny and new? That's because it has a limited cycle life. Which is one thing when you're talking about a phone. And something else entirely when it involves a whole car.) What's more, there is reduced mass for a solid-state battery. And there isn't the same safety concern that exists with li-ion batteries vis-a- vis conflagration (which is why at airplane boarding gates they say they'll check your carryon as long as you remove all lithium-ion batteries). Lithium-ion batteries may be far more advanced than the lead-acid batteries that are under the hood of essentially every car that wasn't built in Fremont, Calif., but as is the case with those heavy black rectangles, li-ion batteries contain a liquid. In the lithium-ion battery, the liquid, the electrolyte, moves the lithium ions from the negative to the positive side (anode to cathode) of the battery. In a solid-state design, there is no liquid sloshing around, which also means that there's no liquid that would freeze at low operating temperatures. What Toyota is using for its solid-state battery is still unknown, as is the case for the solid-state batteries that Hyundai is reportedly working on for its EVs.

2014 Toyota Tundra to debut at Chicago Auto Show

The fullsize pickup market is dominated by trucks from Ford, General Motors and Ram, but this segment could get some hefty competition in coming years. We've already reported that Nissan is planning a redesign of its Titan truck for 2015, and now Toyota has announced that it will be revealing the 2014 Tundra next month at the Chicago Auto Show.
In the brief press release posted below, Toyota says that the 2014 Tundra will be "redesigned," but it's unclear as to whether this means we'll be seeing an all-new truck or just an extensive refresh. The current Tundra design has been around since 2007 and sales are hardly worrisome to the Big Three, so a new design would be a logical guess.
In any case, we only have to wait a couple more weeks for the new Tundra to debut on February 7, and we'll be on hand to bring you plenty of live coverage from the show.
