Toyota Is Uneasy About the Handoff Between Automated Systems and Drivers (caranddriver.com)
schwit1 shares a report from Car and Driver: Toyota has not yet decided whether it will bring a car to market that is capable of automated driving in some situations yet still requires a human driver behind a wheel who can take control if needed -- but the automaker, characteristically, is more cautious than many about moving forward with the technology. Citing safety concerns regarding the handoff between self-driving technology and human driver, Kiyotaka Ise, Toyota's chief safety technology officer, said the biggest issue with these kinds of systems is that "there is a limbo for several seconds between machine and human" in incidents when a car prompts a human to retake control if it cannot handle operations. These kinds of systems, defined as Level 3 autonomy by SAE, have divided automakers and tech companies in their approaches to developing cars for the self-driving future. As opposed to Level 2 systems, like Tesla Motors' Autopilot, in which a human driver is expected to keep his or her eyes and attention on the road while a system conducts most aspects of the driving, Level 3 is characterized by the system's claiming responsibility for the driving task when it is enabled. Although Toyota assures us that its researchers are hard at work figuring out the challenges of Level 3 autonomy, it seems like the company could eventually join others moving directly from its current Level 2 system to a Level 4 system. Given the self-driving race has been on for a while, this could put Toyota at a competitive disadvantage, but it's clear engineers at the company care more about getting things right than they do about being first. -
Standard For Electric Car Charging Announced
SchrodingerZ writes "The Society of Automotive Engineers (SAE), an international syndicate, has unveiled what is to become the standard for electric car charging. In today's market there are hundreds of different methods and plugs to charge a variety of different cars, now a single multi use plug is announced as the world standard. Called the J1772 , it 'has two charging plugs incorporated into a single design and is said to reduce charging times from as long as eight hours to as little as 20 minutes.' The cumulative work of over 190 'global experts,' the plug can cater to both AC and DC currents for charging. The plug also sets a new standard on safety regulations, including 'its ability to be safely used in all weather conditions, and the fact that its connections are never live unless commanded by the car during charging.' The J1772 beat out its Japanese competitor the CHAdeMO, used as an option on the Nissan Leaf." -
Can Your Car Get 1,700 MPG?
Xaroth writes "Given all the hubbub over EPA mileage ratings, I'm a little surprised that this one hasn't come up earlier. SAE apparently holds a contest each year to encourage students to design single-person, fuel-efficient vehicles. This year's winner achieved 1,747.4 MPG, with the press release that tipped me off pointing out that third got a 'measly' 1,194. There are more details on the competition over at SAE's site about the competition. Now, if only they could make these street-legal..." However, even the winner has nothing on top entries we mentioned in Shell's competition a few years back. -
