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 to display turbocharged LF-NX Concept at Tokyo Motor Show

Concept cars typically have a short lifespan. They debut at a major international auto show, then make the rounds of the lesser local shows, and that's pretty much it. They might be loaned out for test drives or put on display in a museum, but by and large they've had their fifteen minutes of fame by that point. That said, Japan's automakers have found a way to keep these show cars going and keep them in the news. They're modifying them and giving them a fresh lease on life.
That's what Subaru is doing with the Viziv concept for the upcoming Tokyo Motor Show, and what Lexus is doing as well with the LF-NX concept. Having already unveiled the crossover concept at the Frankfurt Motor Show, Lexus is fitting the LF-NX with a new 2.0-liter turbo engine. (But then, as far as we could tell, Lexus never revealed engine specs for the concept in the first place.)
To go with the turbo engine, Lexus has also fitted the concept with a new front splitter, but otherwise it's the same - and even appears to be wearing the same liquid-metal paint, unlike the LF-LC concept that got repainted from red to blue when its limelight was starting to fade.

Lexus files to copyright LC 500 nameplates [UPDATE]

UPDATE: Reached for comment, Lexus told Autoblog that it "cannot offer comment on the potential naming of a production version of the LF-LC concept" and pointed out that automakers trademark nameplates as a matter of course. Some automakers already slap a production-ready name on their concepts, but not Lexus. The Japanese automaker typically labels its show cars with the letters LF-XX. So when we heard that Toyota had green-lit the LF-LC concept for production, we naturally started wondering what name the production version would carry. But if the latest intel is any indication, we can stop wondering. According to Lexus Enthusiast, the automaker has filed to trademark the names LC 500 and LC 500h in a variety of markets – including the United States, Canada and Australia. The application tells us a number of things: first of all, that the LF-LC will retain that second set of letters along the road to production (like the NX but unlike other recent Lexus concepts). And secondly, it indicates what engines we can expect to find under the hood. The 500 designation would seem to suggest that the base version of Lexus' upcoming halo sports car will pack the 5.0-liter V8 from the RC F. The bigger question mark is over the hybrid version. Current gasoline-electric models in the company's lineup include the RX 450h (based on a 3.5-liter V6) and the LS 600h (with a 5.0-liter V8). For the LC 500h, Lexus could be planning a more potent electric motor to mate to the 3.5L V6, or planning a new powertrain altogether.
