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."

Lexus resurrecting SC name for big, expensive coupe

Lexus is preparing the SC nomenclature for its third act, after the first bombshell SC coupe from 1991 and the second, Desperate Housewives hardtop convertible evolution from 2001. The brand is aiming again for something that makes a deep mark, with rumored specs pointing to a large, heavy, powerful coupe that will square its spindle grille up against the Mercedes SL and BMW 6 Series. It will be built on the frame of the next-generation LS sedan, and Automobile says internal combustion motivation will come in three flavors. The starter will be a juiced-up version of the company's 5.0-liter, naturally aspirated V8, the one that currently makes 467 horsepower in the RC F. Stepping up from there will be some kind of hybrid powertrain good for around 500 horsepower; last year Motor Trend wrote that the hybrid would be based around a V6 ICE with Toyota's coming "multi-hybrid" system. The top step will be a twin-turbo version of the V8 that could exceed 600 hp. Early reports of dimensions have it at 185 inches long, 75 inches wide, and 53 inches tall. It is expected to use the world's first application of a ten-speed automatic transmission. It'll also get the RC F's torque vectoring mechanism for the rear-wheel-drive setup, though Car and Driver says an all-wheel drive option "might be added later." Aluminum and carbon fiber components will help manage weight. Its design will be inspired by the LF-LC concept, and right now its pricing is as murky as its looks. C/D posits an MSRP from $80,000 to $95,000, Automobile figures it will go "past the $100,000 mark," and MT pegs the situation at $150,000. All agree, however, that it will join the retail pipeline as a 2017 model.

Lexus apologizes for anti-EV ad, Plug In America calls it 'outdated'

Anyone who's spent any time learning about the alternatives to the standard fossil fuel-burning internal combustion engine knows that there are arguments to be made for and against all of the main options. They also know that there is barely any refueling infrastructure for hydrogen fuel cell cars in the US, aside form a handful of H2 stations in California and one in South Carolina. Somehow, though Lexus, recently said there was an "established infrastructure" in 20 states in an online video ad on the company's official site. Another part of that site also made unfair negative comments about battery-powered electric vehicles, saying that it takes too long to charge the cars. Read our original post on the matter here. In the ongoing discussion about how the US moves away from inefficient gas and diesel engines, this was seen as a real muck up of the facts. Upon seeing the videos, pro-electric vehicle group Plug In America released a statement to AutoblogGreen (Lexus is owned by Toyota): Hey, Toyota, the 1990s called. They want their outdated anti-EV attack ad back. Plug-in electric vehicles charge while you're sleeping at home, far more convenient than making a trip to a gas station and coming away smelling like carcinogens. Driving on electricity costs about one fifth what it costs to drive the average gas car and about a third what it costs to drive the most efficient hybrid. An electric drive has smooth, instant acceleration which can't be matched by any gasoline engine. If you don't believe me, just ask anyone driving a Toyota RAV4 EV. The videos were produced by Team One, Lexus' ad agency. Exactly where the information came from and how it made it to the website is unclear, but Lexus spokesman Moe Durand said that Lexus apologizes for offending anyone and has taken the incorrect videos down. The company will review all the materials and alter and adjust the campaign as necessary, he said.
