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."

Genesis wins J.D. Power Tech Experience Study for third straight time

The results are out for the J.D. Power 2023 U.S. Tech Experience Index (TXI) Study, which "focuses on the user experience with advanced vehicle technology as it first comes to market and is an early measure of problems encountered by vehicle owners." Its measurement metric is problems per 100 vehicles (PP100), same as with the J.D. Power Initial Quality Study (IQS). The takeaway this year isn't that owners aren't using advanced technologies, as was the case with the 2022 study, or that they're having more problems with them overall. It's that owners of battery-electric vehicles are having more problems with advanced tech than owners of ICE-powered vehicles. According to the study, 17 of 21 features that can be had on both propulsion types — such as remote parking assistance and gesture controls — get lower satisfaction ratings by owners of BEVs, in some cases nearly 20 PP100.  The survey organization says this tracks with what its found in the IQS, where total vehicle problems were "46% higher among BEVs (excluding Tesla) than ICE vehicles and satisfaction is lower among owners of BEVs across nine of 10 APEAL categories than among owners of ICE vehicles." Findings regarding biometric measurements are among those that go against the overall study findings. Whether a fingerprint reader or an eye tracker, car owners in general said "they do not consider them to be useful." In terms of ease-of-use and satisfaction, plug-and-charge capability on EVs gets good marks. This allows EV owners to plug into a public charger and have payment taken care of automatically; the vehicle communicates with any charging station compatible with an automaker's plug-and-play system, so the vehicle can automatically submit a bill for the charging session to a central owner account with no further action needed at the station. Survey respondents noted a mere 6 PP100 and an 88.9% satisfaction.    Among manufacturers, repeat winners took the top prizes. Genesis earned the highest rank for innovation overall and among premium brands for the third straight year. Hyundai not only won the tech innovation banner for mass market brands for the fourth straight year, ahead of Kia, GMC, Ram and Subaru, Hyundai finished in second in the overall standings. On that overall chart, the top five are Genesis, Hyundai, Cadillac, Lexus and BMW. On the premium chart, Genesis is followed by Cadillac, Lexus, BMW and Mercedes-Benz in the top five. It wasn't close from the first to the rest, though.

2018 Lexus LS First Drive | Luxury, performance and the puzzling parts

When one imagines the enormous executive sedan that might be driven by a wealthy lawyer or banker (or their chauffeur), the mind naturally goes to the Mercedes S-Class or the BMW 7-Series. Venerable, enormous and expensive. But for those wanting to keep their driveway a little more understated, we also have the Lexus LS. Sure, it's not as ostentatious as the big saloons from Munich and Stuttgart, but it has a dignified elegance all its own. For nearly three decades, the LS has been a discrete and dependable Japanese luxury sedan. The new 2018 LS, perhaps thankfully, is a bit less discrete. We saw the new-look LS when it was introduced earlier this year in Detroit. Now we know how it drives. We put the 2018 LS through its paces on the traffic-clogged streets of San Francisco and over the Golden Gate Bridge to the twisty B-roads around Marin County and the legendary Skywalker Ranch, where we stopped for lunch. Unfortunately, all in attendance were sworn to secrecy about the details of Skywalker Ranch, but we're free to tell you all about the LS. Here's our one-sentence summary, which can be used to describe many cars to bear the Lexus badge: It's excellent in many respects, odd in a few, and incredibly, massively frustrating in one very important area. Lexus has a brand new 3.5-liter twin-turbocharged V6 paired with a 10-speed automatic transmission, a first for a premium passenger car. It produces 416 horsepower and 442 pound-feet of torque, up from 386 hp and 367 lb-ft from the outgoing naturally aspirated 4.6-liter V8. Lexus engineers are extremely proud of the fuel efficiency of the new engine, which required some clever technical innovations (a longer bore stroke and increased valve angle) as well as tech borrowed from Formula One, including a "laser clad valve seat" that allows for a more direct flow of air into the combustion chamber and a high "tumble ratio." In other words, Lexus figured out how to get more bang out of each gasoline-powered buck. Fuel economy numbers are 19 city, 29 highway, and 23 combined for the RWD version and 18/27/21 for AWD, with the highway numbers particularly helped along by the 10-speed gearbox. It's a torque converter unit, but Lexus promises shift times that rival its dual-clutch-wielding competitors. The LS is no slouch, either. In RWD trim, the nearly 5,000-pound car hustles from 0-60 mph in 4.6 seconds, according to Lexus' reckoning.
