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."

The Lexus LC 500h has a four-speed auto and that's a good thing

Lexus is sharing some powertrain details on the LC 500h ahead of the big hybrid coupe's debut in Geneva. Its new gas-electric setup strays from Toyota's tried-and-true system found in everything from the Prius to the Lexus GS. It's called the Multi Stage Hybrid System that's designed for performance vehicles, and it has an antiquated-sounding piece of equipment buried deep inside that's supposed to make it more enjoyable to drive. The basics: In the LC 500h, its first application, the Multi Stage Hybrid System will consist of a 3.5-liter V6, a hybrid transmission, and a lithium-ion battery pack. The hybrid transmission has an electric motor for motivation (and we're guessing a second for charging) and a four-speed automatic mounted to its rear, which either means inside or aft and in series. Why add ancient tech to a new hybrid system? Lexus says it preserves the connection between throttle input and engine speed that gets lost in a CVT. And while four seems like an insignificant sum in the face of nine- and 10-speed autos, remember that it is an infinite increase in gear count compared to CVT-packing hybrids. Toyota has been using versions of the Hybrid Synergy Drive system since the first Prius debuted in 1997, and the same system is sold under the Lexus Hybrid Drive banner in most of the luxury brand's offerings. These systems use what Toyota calls an e-CVT – two electric motors paired with a planetary gearset. This lets the engine and electric motors share the job of propelling the car – one motor handles charging of the battery and the other is primarily used to drive the wheels but can also recoup energy through regen. Like a conventional CVT, the planetary gearset arrangement allows the gas engine to run at its optimal engine speed when called upon for motivation and/or charging. But that doesn't make for the most exciting or familiar driving experience, as it affects both power delivery and the sound of the power being delivered. This is where the four-speed auto comes in. Based on the limited details Lexus has shared, our hunch is that the hybrid transmission will meld some form of the existing Lexus Hybrid Drive system with two more planetary gearsets, or the basic guts of a four-speed auto. This will provide the four fixed ratios and the feeling of actual shifting gears – because there will be actual gears shifting.

Lexus LC 500 dominates 2016 EyesOn Design Awards

The Lexus LC 500 captured top honors for the best-designed production car and the best interior at the 10th annual EyesOn Design awards at the Detroit Auto Show. The awards are handed out by the Detroit Institute of Ophthalmology. The Buick Avista won the concept car category, just as its four-door predecessor, the Avenir, did last year. Other winners this year included the Chrysler Pacifica, which won for the best-designed production "truck" (as crossovers and minivans are sometimes categorized), and the Audi H-Tron Quattro, which won for the best concept truck. The Acura Precision concept was also recognized for its "innovative use of color, graphics, and materials." And the new Volvo S90 was singled out for its human-machine interface. The panel of jurists this year included designers from an array of automakers and art schools. Several past honorees for the organization's LifeTime Design Achievement Award participated in the voting, including GM's Wayne Cherry, BMW DesignworksUSA founder Chuck Pelly, Hyundai's Peter Schreyer, and Jack Telnack (formerly of Ford). Telnack also served on the select panel of chief judges this year, alongside Chris Chapman from Hyundai, Dave Marek from Acura, and Stewart Reed from the Art Center College of Design. Lexus Takes 2 and Buick Wins Best Concept For 2nd Year at EyesOn Design Awards at NAIAS January 12, 2016, Detroit, Michigan. A panel of design leaders representing worldwide automotive manufacturers and transportation design chiefs from top design schools around the globe today selected these vehicles to receive the following EyesOn Design Awards at the North American International Auto Show: * Production Car: 2017 Lexus LC500 * Production Truck: 2017 Chrysler Pacifica * Concept Car: Buick Avista Concept * Concept Truck: Audi h-tron Quattro Concept * Best Designed Interior: 2017 Lexus LC500 * Innovative Use of Color, Graphics and Materials: Acura Precision Concept * Human Machine Interface: 2017 Volvo S90 Chief Judges were: Chris Chapman of Hyundai, Dave Marek of Acura, Stewart Reed of ArtCenter College of Design, and Jack Telnack of Ford Motor Company (retired). 2016 marks the tenth year the EyesOn Design Awards have been an integral part of the North American International Auto Show.
