Toyota reveals latest autonomous tech test bed

Toyota revealed its latest autonomous technology effort Friday, a sophisticated Lexus LS 600hL prototype that showcases its plans to advance in the emerging field. The Lexus is the first developed entirely by the company's in-house Toyota Research Institute and it will focus on the car's ability to learn and see behavior on the road. Toyota is showing the car at the Prius Challenge event at Sonoma Raceway. The Lexus uses Lidar, radar, and sensors, which potentially reduce reliance on mapping. The prototype advances Toyota's last concept vehicle shown at the Consumer Electronics Show in 2013. This one is said to be more flexible and it will focus on Toyota's two autonomous tech pillars, called Guardian and Chauffeur. Guardian is meant to improve safety features, while Chauffeur moves toward full autonomy. "We believe Guardian can probably be deployed sooner and more widely than Chauffeur, providing high-level driver-assist features capable of helping mitigate collisions and save lives, sooner rather than later," Toyota Research Institute Gill Pratt said in a statement.

5 stars in Euro NCAP crash tests for 5 new cars available in U.S.

Seven new cars have received a full five-star rating in the latest Euro NCAP crash tests. Of these, five are available in the United States: the Audi E-Tron, Lexus UX, Toyota Corolla, RAV4 and Mazda3. The Renault Clio and the Volkswagen T-Cross also took part, also receiving five stars. The Mazda3 hatchback was the fourth car in Euro NCAP history to reach an adult occupant protection score of 98%, after the Volvo V40 and XC60 and the Alfa Romeo Giulia. No NHTSA ratings for the Mazda3 or the Audi are yet available, but the Lexus and the Toyotas have all received five-star NHTSA safety ratings as well. Those three were tested as hybrid variants by Euro NCAP. Audi's first fully electric vehicle, the E-Tron, scored 91% in Euro NCAP's adult occupant rating, with unavailable knee airbags bringing down the score. The Mazda and the Toyotas offer them for the driver only, and the Lexus has the passenger's knees covered as well. The Lexus UX managed a 96% adult occupant score, close to the Mazda, and it provided better pedestrian safety (82%) than the Audi (71%), despite neither, or none, of the test vehicles having an active hood to catch pedestrians. As for the Toyotas, the Corolla, tested in both sedan and hatchback guises, scored 95% for adult occupant safety, with the RAV4 a couple notches down at 93%. Still, the five-star rating means all these vehicles are a very safe choice in their respective classes. Michiel van Ratingen, secretary general of Euro NCAP, states how important it is that even family hatchbacks perform well and have the latest safety tech available. "It is encouraging to see that all manufacturers did well, regardless of type of powertrain or class of vehicle tested," said van Ratingen. "New cars on the market continue to offer more advanced technology as standard, systems that were not even considered an option a few years ago." More crash test videos are available on Euro NCAP's YouTube channel. Audi Lexus Mazda Toyota Car Buying Safety audi etron lexus ux

Toyota finds 10% MPG improvement in hybrid PCU

Keeping up its from-all-angles approach to efficiency, Toyota has found yet another way to eke out up to ten percent more precious MPGs in its hybrid vehicles, this time electronically. The automaker has announced the development of new silicon carbide (SiC) power semiconductors for use in power control units, which it will begin testing on Japanese roads within the next year. The PCU using the silicon carbide compound offers less electrical resistance, which improves efficiency when passing current between the battery and electric motor. It also loses less power after shutting off, and can operate at a higher frequency. The net power loss of the new PCU is just one-tenth of the current silicone-only version (the latter accounting for 20 percent of total electrical power loss in today's hybrids). The result, so far, is a claimed five-percent improvement in fuel economy in test vehicles, with the potential of ten percent by the time the new SiC power semiconductor comes to market. Additionally, the carbide wafers allow for smaller a power module, coil and capacitor, thus allowing the entire PCU to be 80 percent smaller (see the side-by-side comparison in the accompanying photo, which you can click to enlarge). We've got a while to wait before we start to see the carbide technology to start making a real-world impact. Toyota aims to begin using the SiC units in 2020. By then, with improvements in the company's other key efficiency factors - engine technology and aerodynamics - cars like the Prius will likely see significant gains in fuel economy. Read more in the press release below. Toyota Develops 'Diamond-like' Computer Chips to Boost Hybrid Mileage May 20, 2014 Toyota City, Japan – Toyota is using one of the hardest materials in nature after diamonds to develop a semiconductor chip it hopes will improve the fuel efficiency of its hybrids, such as the Prius, by as much at 10 percent. The company and its partners announced today that they have developed a silicon carbide (SiC) power semiconductor for use in automotive power control units. Toyota plans to begin test-driving vehicles with the technology on public roads in Japan within a year. The chips, made from carbide - one of the hardest materials in nature, theoretically have superior characteristics such as one-tenth the electrical power loss and 10 times the drive frequency. Toyota said the chips would also allow it to reduce the size of current automotive power control units by 80 percent.
