Google self-driving car badly damaged in accident but wasn't at fault

A self-driving Lexus RX 450h hybrid sport utility vehicle owned and operated by Google was involved in an accident in Mountain View, California, on Friday afternoon. Nobody was injured, though there was an occupant inside the Lexus at the time of the crash. Initial reports indicate Google's autonomous vehicle was not at fault. The accident happened when another driver in a commercial van ran a red light and hit the passenger side of the autonomous vehicle. Google confirmed that the vehicle was piloting itself at the time of the accident. When it became obvious a collision was imminent, the human driver applied the brakes, but it was too late. The car sustained significant damage in the crash and had to be towed away on a flatbed trailer. This isn't the first time one of Google's self-driving vehicles was involved in an accident, but it does appear to be the first time one of the tech giant's cars sustained serious damage. In a statement to 9to5Google.com, Google said, "Thousands of crashes happen everyday on US roads, and red-light running is the leading cause of urban crashes in the US. Human error plays a role in 94% of these crashes, which is why we're developing fully self-driving technology to make our roads safer." The United States Department of Transportation earlier this week outlined a set of 15 safety assessment objectives for autonomous vehicle manufacturers to meet. The DOT said "automated vehicles hold enormous potential benefits for safety, mobility and sustainability."

Lexus NX debuts in turbocharged and hybrid guise

Lexus showed off its polarizing new NX at the 2014 Beijing Motor Show, trotting out both the turbocharged 200t model (Lexus' first production turbo) alongside the hybrid-powered 300h.
We still don't know a great deal about the turbocharged model, aside from the fact that the engine underhood is a 2.0-liter four-cylinder, although we're hoping to get details sooner rather than later. For reference, the 2.0-liter turbo in the BMW X1 pumps out 240 horsepower while the four-pot turbo in the Mercedes-Benz GLA250 turns out 208 horsepower, which leads us to think we should expect the Lexus to fall somewhere between these two figures.
If Lexus' naming strategy in the past rings true here, though, we can confidently say the 300h will use a 2.5-liter four-cylinder Atkinson cycle engine with an electric motor and lithium-ion battery, just like the Lexus ES300h and Toyota Avalon Hybrid. That should mean around 200 system horsepower and well over 30 miles per gallon, although it's probably too early to predict economy with any degree of certainty.

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."
