Toyota develops new pre-collision system with steering assist

A number of automakers are working on developing fully autonomous cars, but it looks like the groundwork for such technologies will likely show up first as semi-autonomous systems for both safety and convenience. Following recent announcements from Nissan and Ford in this area, Toyota has now released information for some of its advanced semi-autonomous technologies that could be offered in production cars over the next few years.
On the safety front, Toyota's new pre-collision system with pedestrian-avoidance steering assist is aimed at protecting the folks who aren't in the car. This system combines visual and audible alerts with automatic brake assist and automatic steering. If warnings don't get the driver to slow down, the brake assist kicks in if a collision is very likely, but if that is still not able to avoid the impending collision (and if there is enough room to do so), the car can automatically steer itself around the pedestrian. This sounds most beneficial for last-second dangers such as a person accidently stepping out into the road in front of a car. Toyota hopes to have this technology available to customers by 2015.
The Japanese automaker is also testing a suite of technologies called Automated Highway Driving Assist (AHDA). The key part of this is a new adaptive cruise control system that uses vehicle-to-vehicle (V2V) communications rather than a radar-based system. This cooperative-adaptive cruise control allows vehicles to communicate their acceleration and deceleration data with other cars, which Toyota says this helps to improve fuel efficiency and traffic flow. Also a part of AHDA is the Lane Trace Control feature, which sounds like a next-gen lane keep assist. This system uses cameras, radar and a computer to keep the vehicle in a "smooth driving line" by being able to change steering angle, engine torque and braking force. Toyota says this technology could be in place by the "mid-2010s."

2014 Lexus IS350 F-Sport

Is A New Kind Of Lexus Hiding Under That Radical Skin?
When the now-outgoing Lexus IS generation was launched back in 2006, the company would not have been wise to bring the compact luxury sedan to be driven by journalists to a track like Driveway Austin Motorsports. Taking along a BMW 335i for comparison loops would have proved an ill choice as well.
Our own Jonathon Ramsey found the current-generation Lexus IS250 to be fairly nimble over a tightly wound autocross course, when he drove it back-to-back with the prototype version of this 2014 IS a few months ago. Our track for testing the fully realized version of the IS350 F-Sport meanwhile - again with the 2013 version along for competitive driving - was on a circuit designed to string together recreations of some of the best tracks in the world. Laguna Seca, bits of the Nürburgring and sections inspired by Imola and Ferrari's Fiorano test track all make for a far more enticing road course than you'd expect to find plunked down in a nondescript area a few miles east of downtown Austin. Critically, this environment highlighted what strides Lexus has made in the sport sedan race with its new IS.

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.
