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 RC media event in Japan canceled over lack of interest

It's a good thing senior editor Seyth Miersma doesn't live in Japan, or he wouldn't have been able to snap a photo like the one you see here, of a fresh-off-the-line Lexus RC F on hand at a first drive for media. That's because Toyota's Japanese arm has outright canceled its RC press launch. Sure, we've heard about events being delayed, but canceled? That's rare. Even worse is the reason: according to Automotive News, the event was nixed due to lack of interest. Wow.
In an email to media, Lexus said the event "has been canceled due to insufficient attendance," according to AN. The News posits that perhaps it would have just been better to hold the event anyway, in an attempt to save face, and that this is another example of the Japanese culture (especially youth) becoming less and less interested in cars. Of course, there's also the thought that local media just didn't want to drive out to Yokohama to drive the RC on a not-so-sexy press launch, which, if you ask us, is an incredibly lame excuse (do your jobs, folks!).
Either way, will this bode well for the Lexus RC's public launch? Will it receive the same lukewarm response when it arrives at Japanese dealers? We'll see.

Lexus exploring PHEV, full EV and fuel cell versions of LS flagship

After four years of rumors about a Lexus LS powered by a hydrogen fuel cell, the chief engineer of the flagship sedan says the carmaker's working on even more options. Toshio Asahi told Australia's GoAuto that three alternative powertrains — plug-in hybrid, full electric, and hydrogen — are "all on the table" for consideration. Asahi wouldn't give any timeframes, but whenever they arrive, additional drive options would fill out the LS range to better contend with the Germans. Years of reports predicted this fifth-generation LS would get hydrogen power. A Motoring article at the end of 2014 forecast a fuel cell LS to arrive by 2017. In 2015 Japan's Nikkei newspaper reported that Lexus was considering a fuel cell option to arrive in 2020, around the time of the Tokyo Olympics. Later that year, at the Tokyo Motor Show, Lexus showed off the LF-FC concept, powered by a cell and stack arranged for "optimum front-rear weight distribution for a sporty saloon." GoAuto said that during that show, a Lexus executive said an FCEV powertrain would end up in production "sooner than you think." The following year, Autocar reported we'd see a production version of the LF-FC "on sale before 2020" as a replacement for the LS, and last year, Lexus trademarked the name "LF-FC Concept." The intel gets murkier regarding plug-in hybrid and full electric versions. We now know Lexus is working on a more powerful hybrid system. The current hybrid produces a total system 354 horsepower and 258 pound-feet of torque using the same 3.5-liter V6 in the standard car as a base, though the standard car adds two turbos for 415 hp and 442 lb-ft. The coming hybrid will likely use the twin-turbo setup and could achieve two important ends: Smoothing out noted issues of powertrain refinement, and at least matching the power specs of Mercedes-Benz and BMW flagship plug-in hybrids. That hybrid LS would still miss out on the all-electric driving of its rivals. If there really is an LF-FC coming in the next two years, it would seem a perfect time to retire the conventional hybrid and introduce a plug-in version embodying the velvet sophistication Lexus is known for. The battery electric LS is a big question mark outside of Lexus HQ. Last year Toyota announced a breakthrough in solid state battery technology, the carmaker announcing it wanted such batteries on the market by 2022.
