177k Toyota Camry Hybrids being recalled for brake issue

It looks like Consumer Reports might be getting part of what it wants regarding the Toyota Camry Hybrid and its braking system. Toyota is issuing what it calls a limited service campaign, rather than a full recall, covering about 177,500 of the hybrid sedans from the 2007 through 2011 model years because of an issue with the cars' brake fluid reservoirs.
The models have a filter separating two chambers of the brake fluid reservoir, and the part can get clogged over time. If this happens, the fluid level in one of the chambers can get too low and eventually cause the power assist to fail. There are multiple warning lights on the dashboard that illuminate over time if the filter gets obstructed, though. The company is replacing the entire reservoir with an improved unit, and the fix takes about two hours to perform.
Consumer Reports recently began asking for a recall on these models for the potentially clogged filters. The magazine also reported a second issue with the ABS brake actuator that could lead to a difficult to depress brake, but Toyota has increased the warranty on the part to 10 years or 150,000 miles.

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."
