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:

Toyota, Lexus recall 460,000 vehicles for stability control issue

Toyota and its luxury subsidiary, Lexus, are recalling 460,000 electrified models produced for the 2020-2022 model years to address an issue that can cause the vehicles' stability control systems not to activate on startup. If you drive a new Toyota or Lexus and it has at least one electric motor in it (or it's the new LX 600), there's a better-than-even chance you'll be hearing from your dealer in the coming months. The good news for owners is that the issue is one of compliance, rather than something which may immediately endanger a vehicle occupant.  "A software error can cause the Vehicle Stability Control system (VSC) not to default to ON the next time the car is started under certain circumstances. This can result in a noncompliance with applicable regulations in the U.S," Toyota said in its announcement. "For all involved vehicles, Toyota and Lexus dealers will update the software of the Skid Control ECU free of charge to customers." Included in the campaign are the 2020-2022 Toyota Venza, Mirai, RAV4 Hybrid, RAV4 Prime, Sienna Hybrid, and Highlander Hybrid. On the Lexus side, it hits the LS500h, LX600, NX350h and NX450h+. Notably absent here are the Tundra-based trucks with the new iForce Max hybrid, though Toyota may have addressed the issue in those models before they went on sale. On the other side of the coin, the LX 600 — a purely ICE model for the time being — managed to stumble into the defect pool.  Toyota says owners should receive notices before the end of June.

Mazda-Toyota partnership has us dreaming of a rotary hybrid

As you may have seen, Mazda and Toyota are going to be working a little more closely with each other. In their announcement, the two companies said they'd be building an American assembly plant together, and working on electric vehicle technology. But one of the companies' goals got our mental gears turning: It's listed as "Expand complementary products," and it's left very open-ended. The companies say they "will further explore the possibilities of other complementary products on a global level." These are in addition to Mazda providing the Mazda2 to Toyota as the Yaris iA, and Toyota providing Mazda a commercial van to sell in Japan. So what could these future complementary products be? We have a couple of ideas, one that's ludicrous but awesome (and, sadly, probably won't ever happen), and the other grounded in reality. Let's start with the fun one. What's the one thing Mazda fan has been wanting for years? A rotary sports car, of course! And while Mazda has repeatedly said that it has a small band of engineers plugging away at the spinning triangle problem, the odds of Mazda putting it into production have been slim. The inherent thirst of the rotary would make it tough to introduce when fuel economy regulations have been tightening. Plus, Mazda is a small company that needs to stretch every dollar, and having a one-off engine not based on anything else would be expensive. How could Mazda get around these obstacles? This is where the partnership with Toyota comes in, in our long-shot fantasy. Aside from having deep pockets, Toyota has a wealth of knowledge in the realm of hybrids. Thus, why not a rotary hybrid? Electrifying their oddball motor would fix two issues. One is obviously the fuel economy, since the gas engine wouldn't have to run all the time. The other is in providing torque. Rotaries infamously have little torque, especially down low, so adding an electric motor would allow this hypothetical rotary sports car to have a grunty low end, while still providing the Everest-high redline rotary fans like. The idea would be sweetened with the solid-state batteries that Toyota is developing, which could provide lots of electricity without weighing a ton. The rotary-electric mashup notion isn't totally alien to Mazda, either, since the company created an electric Mazda2 with a rotary engine for a range extender — albeit for different reasons. The company even filed a patent for the rotary range extender recently.
