Google shares more details on self-driving car accidents

Google has pledged to release monthly reports on the status of its self-driving car program, and says these updates will include information on accidents involving the vehicles. But the company won't release the actual accident reports, a sore point for activists who recently have clamored for the company to be more transparent in the way it tests this promising technology on public roads. "Google is dribbling out bits of information in the hope to silence legitimate calls for full transparency," said John Simpson, privacy director for Consumer Watchdog, a nonprofit that has asked Google to release reports from the 12 accidents the company says it has been involved in over the past six years. "They are testing on public roads, and the public has a right to know exactly what happened when something goes wrong." Under California law, the accident reports are not considered public records. Google has attributed all accidents to human error, and says drivers of the other cars involved caused 11 of the 12 accidents. In eight of those, the Google cars were rear-ended, and the autonomous vehicles were sideswiped in two other crashes. One of the accidents occurred at an intersection when a human driver failed to yield at a stop sign, and in one incident, a Google driver accidentally rear-ended another car while manually driving. Google had previously provided those details. The first monthly report installment sheds new light on which types of self-driving vehicles were involved, directions of travel, locations, and whether the cars were operating in autonomous or manual mode. Update: Google says this information comes directly from the OL 316 forms used to report accidents involving autonomous cars in California, though it has "edited the summaries lightly to protect other drivers' information." But Google still will not release the original OL 316 forms, nor the "traffic collision report" forms used in California to report accidents. Another company that has been involved in a single self-driving car accident, Delphi Automotive, has released this information, which verified its car was not at fault. Regarding Google, Simpson said, "We now know a few more details of what happened. The problem is that it's Google's version and they want us to take their word for it." The Google self-report adds information that goes beyond accidents, with further details on the company's overall program.

'Next Lexus F' teased ahead of Detroit debut

We've got absolutely zero actual information from the automaker on what its "Next Lexus F" will be, other than what was just released today in this brief press release and lone teaser image, but our best guess is that it's the next-generation IS-F sedan. The timing would make sense, considering that the latest IS just hit the market earlier this year as a 2014 model.
Since we know so little, we'll just share some of the exuberant marketing speak contained in the press release for your reading pleasure:
Designed from the asphalt up, to strike at the heart, the newest Lexus F model will debut at the January 2014 North American International Auto Show in Detroit.

8 things you should know about the Lexus LC 500h powertrain

Lexus unveiled the LC 500h today in The Netherlands, and I got to take a look inside its new hybrid system. On one hand it seems like a box of magic – it combines two seemingly incompatible transmission types into one package. But that's also the ingenious simplicity of the thing. We don't have all of the details on how it all works yet, but here's a rundown of the high points.Efficient business in front, low-key party in the back. What makes it all work is the mullet of transmissions. For the new hybrid transmission, Lexus used the Toyota Hybrid Synergy Drive/Lexus Hybrid System – which consists of an e-CVT with a planetary gearset and two electric motors (one for charging the battery, the other for motivation and regen) – and grafted a conventional four-speed automatic onto the back. The two units actually coexist in one package, with the e-CVT making things efficient and the automatic expanding the capabilities. So at the low end, the system can deliver more torque, and the engine can also run at lower rpm on the highway. It's all thanks to those fixed gear ratios, and it's surprisingly simple.Except it's not that simple. This is where the virtual gear ratios come in. Like current Lexus hybrids, the system has ratios it can call up with the e-CVT. In this case, there are six virtual ratios to complement the four real physical ratios, for a total of 10 "gears" at the transmission's disposal. (Not coincidentally, the V8 LC 500 coupe has a 10-speed automatic.) One of the four fixed gears is always engaged when the car is moving, so the 10 ratios come about from combinations of what the e-CVT in front and the automatic in the back are doing. In other words, all 10 ratios are variations on the four fixed gear ratios, which means that all 10 gears could be considered virtual.It won't use all the gears all the time. In Eco mode, the car will start off on electric power and skip the first couple of "gears." When it's set to Sport or Sport +, the engine will be engaged from a stop and the transmission will select the lowest ratio. The sportier modes will also ignore the top couple of gear ratios.It can drive faster with the engine off. In a Lexus GS 450h with the Lexus Hybrid System, for example, at speeds above 62 mph or so the engine has to start up. This is because something needs to take up some slack from the battery-charging motor-generator or else it will start spinning too quickly.
