NHTSA Readies New Voluntary Autonomous Driving Database

The National Highway Traffic Safety Administration (NHTSA) plans to release new guidance for automakers to make autonomous testing data available to the public. As you are no doubt aware, the concept of self-driving cars is losing steam. The industry finds itself confronting hurdles it never could have anticipated, slowing progress, while high-profile mishaps have shaken the public’s faith.

While polling has hardly been consistent (and often conducted by actors who frame the questions to get a desired answer), reputable outlets have shown us that public acceptance of self-driving cars declined over the past few years. The NHTSA would like to offset this by allowing regular folks to more easily track the industry’s progress, while encouraging a bit of competition among companies as they compare themselves to each other in a new database.

SAE Consumer Autonomous Driving Study Finds… Public Acceptance?

With the realities of autonomous driving growing increasingly apparent, the Society of Automobile Engineers (SAE) decided to conduct a survey to gauge public sentiment surrounding the technology. We’ve seen these studies before, noticing a lack of consistency. While several high-profile accidents relating to autonomous (or semi-autonomous) systems have clearly shaken people’s confidence over the last two years, we’re still seeing conflicting reports — and we don’t mean minor discrepancies, either.

The SAE survey, published on Tuesday, stated that 76 percent of respondents “think a self-driving car experience is similar or superior to a human-driven experience.” However, the American Automobile Association (AAA) released a study in March claiming 71 percent of survey respondents still had serious concerns with the technology, with only 19 percent claiming they’d even consider putting a loved one in a self-driving vehicle.

That’s a complete turn-around in just over six months. Perhaps we should look at how these surveys are being conducted and the type of questions being asked, because taking the SAE Demo Days Survey at face value makes it seem as though automated driving has finally gained public acceptance.

With New Technology Comes New Ways to Die

Since 2005, 37 deaths by carbon monoxide poisoning have been attributed to vehicles with keyless ignitions that were inadvertently left running. Automatic engine shutoff is not currently mandated by the National Highway Traffic Safety Administration, so manufacturer’s application of the technology is sporadic. But the PARK IT Act wants to change that.

Piston Slap: Blinded by the Light or BGE Clarity?

Looooooongtime TTAC reader Robin writes:

Even after all these years on the road (driving since 1972) there are still situations that raise the hackles on my my neck. This is my cautionary tale.

The other day I was on 75, heading south to Dallas, from McKinney. It was around 6:00 a.m., a good hour before sunrise. I like to stay in the next-to-the-outside lane, leaving the furthest right hand lane for drivers entering the freeway. So I began my scan to move over one.

Immediately behind me was a late model, full-sized truck. They are high enough that those headlights pretty much flood my rear vision. I could see that he was NOT attempting to overtake me, either. But there was something in my field of vision. It was vague, flooded out by those projector headlights. I hesitated before moving. And sure enough, here came a guy on a motorcycle, passing us all. He was not driving recklessly at all. Yet I could not see him for the briefest instant as he traversed through the glare of those projector beams.

I don’t know what would have transpired, we were all tucked in pretty damned closely.

Bottom line is, no matter how safely one is operating their vehicle, no matter how safely everyone else is operating, it only takes a literal second for things to go sideways.

Suppliers Rule! The PACE of Automotive Innovation

Suppliers are integral to new technology in the auto industry to an extent not true since the early years of the 20th century, when ventures such as Ford began as mere assemblers, not manufacturers. That will be highlighted on Monday at the 21st PACE “academy awards” for supplier innovation. (For those not in the know, Monday’s the opening night of the SAE [Society of Automotive Engineers] in Detroit.)

Vox Explains: Don't Use A/C – Roll Up Windows & Wear an Ice Vest to Save Gas

It’s always nice when you come across an answer that addresses a question that you’ve wondered about? When I saw that Vox, a relatively new site that says it has “the smartest thinkers, the toughest questions” to “explain” our confusing world to us, was running a post on which uses less fuel, running the A/C or opening the windows, I figured I could put the question to bed. While I did find out about the windows down vs air conditioning thing, I also found out that the smart thinkers over at Vox may not be as smart as they think they are.

Original Documents: The Corvette Story (Circa 1961) by P.J. Passon

Okay, so it’s not The Christmas Story, but while trying to track down a since deleted summary of an upcoming Society of Automotive Engineers paper that leaked details of the 8 speed automatic transaxle that the 2015 Corvette will offer, I came across another SAE paper concerning the Corvette, this one published in 1961, titled The Corvette Story. In 1961, just 8 years after the first Corvettes went on sale, fiberglass bodied cars were still a new thing. Chevrolet engineer P.J. Passon’s paper for the SAE goes over the processes involved in making the Corvette bodies and then how the cars are assembled. He discusses the 1961 Corvette’s engineering features and explains why GM went with fiberglass instead of steel and also why mass-market Chevrolet was making and selling a sports car with limited market appeal. I’m sure that anyone with an interest in Corvettes and Corvette history will find it worthwhile, though it’s also a nice snapshot of advanced materials manufacturing circa 1961.

In its brief life span of eight years, the Corvette has undergone rapid character development. It has built up a clientele all its own – demanding, but enthusiastic. Their attitude is contagious, and progress has come fast. I do not intend to cover the history of the Corvette this morning, except to say that its roadability has increased since 1953 in roughly the same proportion as its power-to-weight ratio or approximately two-to-one.

SAE Paper Summary Leaking 2015 Corvette's 8 Speed Auto Gets Redacted

It’s not known if the leak was intentional or not, but the summary of a paper initially published by the Society of Automotive Engineers, since taken down from the SAE site, says that a new eight speed automatic transmission, given the designation 8L90 by General Motors, will be introduced in the 2015 Corvette, on sale next fall. The all-new 7th generation Corvette is currently offered with GM’s 6L80 six speed automatic and a seven speed manual gearbox. The 8L90 is described as being designed for rear-wheel-drive applications and variants will likely be used in GM’s fullsize pickups and in rear wheel drive Cadillacs.

The 8L90 has about the same overall dimensions as the 6L80, and is said to be able to handle up to 737 lb-ft of torque. It has a shorter first gear for better launch acceleration, an overall ratio spread of 7.0 and three speed sensors for better shift response. Other benefits are said to be better fuel economy, improved performance and a quieter car with improved NVH levels.

The War Of The Plugs: The Japanese Empire Talks Back

Today, members of CHAdeMO congregated in the 7th floor auditorium of Tokyo’s Big Sight for CHAdeMO’s General Assembly 2012. CHAdeMO is a consortium of mostly Japanese companies with the target of establishing a standard for the charging of EVs. Also in the room was an invisible, but giant Godzilla. They called him “The Combo.” The combo is the product of (in Japanese views) an unholy alliance between U.S. and German OEMs which agreed on their own plug. The CHAdeMO and The Combo are utterly incompatible. Sparks are already flying.

American, German Automakers Show Off Rival Fast-Charging Standard

Even though the Nissan Leaf and Mitsubishi i already have their own standard for “quick-charge” stations – known as CHAdeMO, a standard supported by Nissan, Mitsubishi, Fuji Heavy Industries (parent company of Subaru) – the SAE is apparently pitching its own standard of quick-charger outlets (pictured above), creating a situation that would be akin to having certain cars only compatible with certain gas pumps.

Piston Slap: Playing Super Breakout by Itself?

C.V. writes:

I am a mechanical engineering student looking to learn how to work on cars.

My friend has given me the opportunity to take his 1988 Mazda B2200 extra-cab 5-speed. When I drove it, I saw why. The catalytic converter has broken off, and apparently pieces of it are in the exhaust. Would it be possible to just replace the catalytic converter, or should I replace the whole exhaust?

The Doyle Rotary Engine

One of the cool things about the SAE World Congress is that there’s always at least a couple of radical new engine designs. Scuderi was back with their split cycle compressed air hybrid, only this time with a turbo that lets them use a much smaller piston on the intake side, reducing friction. FEV showed an engine optimized for compressed natural gas, with turbocharging, long intake runners, and a piston designed to increase turbulence. Two exhibitors were at the SAE for the first time. Grail Engine Technologies was showing their atmospheric-valve-in-piston engine that routes the induction through the crankcase and up into the combustion chamber.
