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."

2018 Lexus RX 350L Quick Spin Review | Minding the gap in the Lexus lineup

PORTLAND, Ore. — Why on Earth does Lexus still make the Jurassic GX 460? It's old, inefficient, body-on-frame and completely atypical of the rest of the three-row luxury segment. Well, the answer lies in that segment descriptor: three rows. People want them, yet Lexus didn't offer anything else between the two-row RX and the $85,000, Land Cruiser-based LX 570. Despite this lineup gap lasting for two decades, Lexus decided to finally attempt filling it with a seemingly quick-and-dirty solution: Lengthen the RX 350, shoehorn in a third row, add an L to the name, wipe hands together, call it a day. The resulting 2018 Lexus RX 350L does indeed have a third row of seats and is generally a far superior vehicle to the GX. It's better to drive, massively more efficient, and its beautiful interior is up to the current Lexus norm. The cargo door doesn't swing into the curb. Plus, unlike some other slapped-together lengthened jobs over the years like the Chevrolet TrailBlazer EXT or even the long-wheelbase Range Rover, the RX 350L doesn't suffer visually for its extra inches. In fact, it can be difficult to tell the L apart from a non-L unless the two are parked together in profile. If everything, the extra 4.4 inches of length might actually improve the RX's proportions from certain angles. Of course, quite a few people find the current RX to be hideous, so finding comments below that include the words "lipstick" and "pig" would not be surprising. Adding the L also doesn't seem to take away from the RX's driving experience, which continues to impress. The current model is buttoned down and involving in a way its couch-like predecessors never attempted to be. From the lowered driving position to the more responsive steering, this is a far more driver-oriented vehicle. You don't even need to engage Sport mode, but doing so dials in an appropriate level of steering weight and sharpens throttle/transmission response. This general sportification also hasn't taken anything away from comfort, as a three-hour road trip from Portland to Seattle proved it to be a superb highway cruiser. Both seat and ride comfort are excellent. That was with two people aboard, however. Later in the week, we managed to easily fit an extra pair in the second row along with a rear-facing baby seat. That's all well and good, but the regular RX can do that.

Thanks to smaller engines, vehicle dependability falls for first time in 16 years

As automakers have made engines smaller and smaller to improve fuel economy, problems in those vehicles have gotten bigger and bigger. That's the synopsis of a J.D. Power vehicle-dependability study, which found that dependability dropped for the first time in 16 years, largely because the proliferation of four-cylinder engines is causing the vehicles to be less reliable. Specifically, the number of problems per 100 vehicles (or what J.D. Power calls PP100) during the past 12 months for 2011 model-year vehicles rose six percent from the year-earlier figures for 2010 model-year cars. Singling out four-cylinder vehicles revealed about a 10-percent increase in problems during the past year. This issues largely related to engine hesitation, rough transmission shifting and lack of power, signaling the inability of vehicle makers to iron out some of the problems in their smaller engines as they strove for better fuel economy. Six- and five-cylinder engines proved far more reliable. Among car brands, BMW's Mini sub-brand came out as least reliable, with 185 problems per 100 vehicles during the past year. Toyota's Lexus badge was easily the most reliable, with just 68 problems per 100 vehicles. Coming in second place was Mercedes-Benz. The overall average was 133. Check out J.D. Power's press release below. J.D. Power Reports: Increased Engine and Transmission Problems Contribute to Decline in Vehicle Dependability for The First Time in More Than 15 Years General Motors Company Receives Eight Segment Awards, While Toyota Motor Corporation Garners Seven and Honda Motor Company Earns Six WESTLAKE VILLAGE, Calif.: o Owners of 3-year-old vehicles (2011 model year) report more problems than did owners of 3-year-old vehicles last year, according to the J.D. Power 2014 U.S. Vehicle Dependability StudySM (VDS) released today. The study, now in its 25th year, examines problems experienced during the past 12 months by original owners of 2011 model-year vehicles. Overall dependability is determined by the number of problems experienced per 100 vehicles (PP100), with a lower score reflecting higher quality. The study finds that overall vehicle dependability averages 133 PP100, a 6 percent increase in problems from 126 PP100 in 2013. This marks the first time since the 1998 study that the average number of problems has increased. "Until this year, we have seen a continual improvement in vehicle dependability," said David Sargent, vice president of global automotive at J.D.
