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 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.

Lexus LF-NX gets turbocharged second act [w/video]

Don't let its supremely polarizing appearance fool you, this is not the Lexus LF-NX Concept that you (probably) had a strong reaction to when it debuted at the Frankfurt Motor Show. The German version of the concept car featured a variant of the Lexus Hybrid Drive system, while this LF-NX Turbo, well, it has "turbo" in the name, you see?
If fact, the namesake turbo would appear to be the first for Lexus; getting off the line in the forced-induction race with a 2.0T four-cylinder engine that "paves the way for the introduction of turbocharged powerplants in future Lexus models." Sounds good to us. The new turbo four has plenty of tricky tech, too. Lexus tells us that the engine makes use of an advanced high tumble port, fan spray fuel injection, VVT-iw variable valve timing, an exhaust manifold integrated into the cylinder head and, of course, a twin-scroll turbo with active wastegate valve. The result is said to be a blown engine that offers quick throttle response and "exhilarating" performance, along with excellent fuel economy and low tailpipe emissions.
As for the rest of the LF-NX Turbo concept? Well, you've seen this angular concept crossover before, basically. There's a slightly tweaked front end and new wheels sitting in slightly cleaned-up wheel wells. The boldest-yet version of the spindle grille still bears an uncanny resemblance to The Predator, and the slightly revised exterior visuals won't change your made-up-mind about this vision of Lexus' future.
