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."

Weekly Recap: Toyota propels hydrogen fuel cells

Toyota is serious about hydrogen fuel cells, and it wants the auto industry to follow suit. The Japanese automaker said this week it's releasing 5,680 fuel cell patents from around the world, including technologies used on its upcoming sedan, the 2016 Mirai. The move is unusual, but not unprecedented, as Tesla similarly released its electric vehicle patents last year. The idea for Tesla, and now for Toyota, is to spur development of alternative propulsion. "By eliminating traditional corporate boundaries, we can speed the development of new technologies and move into the future of mobility more quickly, effectively and economically," said Bob Carter, Toyota Motor Sales senior vice president of automotive operations, in a statement. Toyota's fuel cell patents will be free to use through 2020, though patents related to producing and selling hydrogen will remain open forever. Toyota said it would like companies that use its patents to share their own hydrogen patents, but won't require it. "What Toyota's doing is really a logical move, and really a good move for the industry," Devin Lindsay, principal powertrain analyst with IHS Automotive, told Autoblog. The announcement was made at the Consumer Electronics Show in Las Vegas. It comes as Toyota prepares to launch the hydrogen-powered Mirai in a limited number late this year in California. The launch will be extended to the Northeastern United States next year. Toyota also has announced plans to support networks of fueling stations in each region to try to smooth consumer adoption. The Mirai has a 300-mile range on a tank of hydrogen, and it takes about five minutes to refill. Fuel cells have been receiving increased attention recently, and Audi and Volkswagen debuted hydrogen-powered cars at the 2014 Los Angeles Auto Show. Honda, another proponent of the technology, also showed its updated FCV concept in November in Japan. The company, however, has delayed its fuel cell sedan a year until 2016. Like Toyota, Honda says its hydrogen-powered car will have a range of 300 miles or more. Meanwhile, Hyundai currently offers leases for fuel-cell powered Tucsons, which have a 265-mile range, in Southern California. Despite the optimism some automakers have for fuel cells, the technology still faces barriers. A lack of filling stations has long held it back, and many consumers are not familiar with the potential benefits.

Japanese earthquakes send ripples through auto industry

The earthquakes since April 14 in Japan's Kumamoto Prefecture on the island of Kyushu are having aftershocks on the US auto industry, particularly for Toyota. The company shut down most of its factories in the country due to parts shortages, and the plants will be closed at least through April 23. "Decisions regarding recommencement of operation at plants in Japan will be made on the basis of availability of parts," the company said in a statement. According to Automotive News, Toyota's closed factories include a vast range of popular models in the US, including the Toyota Prius, Mirai, RAV4, 4Runner, Land Cruiser, Lexus ES, LS, IS, GS, RC, NX, RX, GX, and LX. The company's only sites in Japan that are still open build Hino trucks, Daihatsu models, and the Toyota Century limo. Toyota isn't yet sure whether these shutdowns could lead to vehicle shortages in the US. "As you can imagine, we are still reviewing the situation and working to learn more," company spokesperson Aaron Fowles told Autoblog. "While we know that production will be suspended in stages at most of our vehicle assembly facilities in Japan between April 18th and the 23rd, we do not know if they will continue production suspensions. Also, any effects to our inventory and/or sales have yet to be determined." He expects the automaker to know more in the coming days. Many of the affected Toyota plants aren't even in Kumamoto Prefecture, but major suppliers have factories in the region. For example, Aisin Seiki and Renesas Electronics both had to shutdown operations at plants in the area, according to Automotive News. Toyota isn't the only automaker affected. Nissan experienced a brief slowdown but was back to work on Monday, and Honda has suspended a motorcycle plant in the region until Friday. Mitsubishi had to close a production line due to the parts shortage, according to The Japan Times, but it didn't affect US models. "A supplier to our Mizushima plant has been impacted but they only supply an engine part for our mini car line. That line has been temporarily shut down due to that situation," spokesperson Alex Fedorak told Autoblog. "That same plant builds the Lancer and i-MiEv and there has been no impact to that line and production continues uninterrupted." Two major quakes hit Kumamoto Prefecture around Kumamoto city in the past week. The first on April 14 measured 6.4 magnitude, and a second on April 16 measured 7.3.
