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."

Toyota Recalls 1.9 Million Prius Hybrids

TOKYO (AP) - Toyota is recalling 1.9 million hybrid Prius cars globally for a software glitch that could cause the vehicle to stall. Toyota Motor Corp. said Wednesday that 997,000 Prius cars in Japan, some 713,000 in North America, another 130,000 in Europe and the rest in other regions are being recalled for a problem in the software to control the hybrid system. No accidents or injuries have been reported related to the problem. The software could cause transistors to become damaged, causing warnings lights to go off, driving power to be reduced or the car to stop. The recalled vehicles were manufactured between March 2009 and February 2014. The Japanese automaker suffered massive recalls starting in 2009, affecting more than 14 million vehicles for problems including floor mats, gas pedals and brakes. Affected vehicles include: 2010-2014 Prius vehicles, 2012 Toyota RAV4, 2012-2013 Toyota Tacoma and 2012-2013 Lexus RX 350 vehicles sold in the United States.

119K Toyota Avalon sedans recalled over airbag woes

Toyota has issued a voluntary safety recall for 119,000 2003-2004 Avalon models because in some cases the airbags could inadvertently deploy.
The automaker says that circuits within the airbag control module could be damaged by electrical noise, which could cause the front airbags and seatbelt pre-tensioners to activate. Dealers are going to repair cars by adding an electrical noise filter to the module. Owners will be notified by first class mail.
Toyota Public Affairs Manager Cindy Knight told Autoblog that there was one reported injury caused by the sudden deployment, but there have been no accidents or crashes. The company is currently preparing the parts for dealers now, and the component takes 90 minutes to two hours to install. "We don't believe there are any other affected models," said Knight.
