Toyota R&D shows off free piston engine linear generator for future EVs

We often hear how an electric vehicle powertrain architecture allows vehicle designers much more freedom than a traditional ICE powertrain does. With differently shaped battery modules and small electric motors, there are lots of way to put the pieces together. With today's plug-in hybrid technology, engineers still need to put a decent-sized ICE somewhere, but new technology from Toyota could free up the gas-electric vehicle designers of the future. Presented at the recent SAE World Congress in Detroit, the idea from Toyota Central R&D Labs Inc. and involves what is called a Free Piston Engine Linear Generator (FPEG). Think of it as a sort of one-cylinder, two-stroke mini-engine that can work either as a generator (thank to magnets and a linear coil) or to directly drive a vehicle. The current prototype is a 10-kW unit that Toyota say would provide enough power to get a B- or C-segment electric vehicle up to highway speeds (75 miles per hour) when paired up to offer 20 kW. Pairing the FPEGs is also important to minimize vibrations. One system tested by Toyota had a 42 percent thermal efficiency, but the engineers are working to improve the overall efficiency even further.

Chip maker Nvidia adds Volvo to list of self-driving partners

Chipmaker Nvidia Corp announced on Monday it was partnering with Volvo Cars and Swedish auto supplier Autoliv to develop self-driving car technology for vehicles due to hit the market by 2021. Volvo is owned by China's Geely Automobile Holdings. Silicon Valley-based Nvidia also announced a non-exclusive partnership with German automotive suppliers ZF and Hella for artificial intelligence technology for autonomous driving. Nvidia came to prominence in the gaming industry for designing graphics processing chips, but in recent years has been a key player in the automotive sector for providing the so-called "brain" of the autonomous vehicle. The company, whose many partners already include Tesla, Toyota, Ford, Audi, BMW, and tier one supplier Robert Bosch, announced its latest deals at an automotive electronics show in Ludwigsburg, Germany. Nvidia's Drive PX artificial intelligence platform is used by Tesla in its Models S and X and upcoming Model 3 electric vehicles. Volkswagen AG's Audi is also using the system to reach full autonomous driving by 2020. In a call with reporters, Nvidia's senior automotive director Danny Shapiro said carmakers and their main suppliers are now moving away from the research and development phase of autonomous vehicles and into concrete production plans. The system developed jointly by ZF and Hella, and using Nvidia's Drive PX platform, will combine front cameras with radar and software to create technology meeting the Euro NCAP safety certification for so-called "Level 3" driving, in which some, but not all, driving is performed by the car. Volvo is already using the Drive PX for the self-driving cars in its "Drive Me" autonomous pilot program. Volvo's production vehicles built on Nvidia's platform, as announced on Monday, are planned for sale by 2021.Reporting By Alexandria SageRelated Video: Auto News Green Tesla Toyota Volvo Technology Emerging Technologies Autonomous Vehicles nvidia autoliv

Toyota has now sold over 7 million hybrids

You take your victories where you can. In Toyota's case, that means disclosing the cumulative total of hybrid sales since the first Prius was sold in Japan in 1997. And that number is impressive. During its monthly conference call discussing sales, Toyota representatives noted that the automaker has sold over 7 million hybrids during the past 17 years. The Japanese automaker started selling the Prius in the Japan in 1997 (and in US in 2000) and firmly established itself as the world's largest hybrid maker. Today, Toyota sells four Prius models as well as gas-electric versions of the Camry, Avalon and Highlander in the US. Of course, such big sales aren't always easy to match, and Toyota's been lagging behind 2013's numbers all year. Including its Lexus division, Toyota's green-car sales including the low-volume RAV4 electric vehicle fell 10 percent from a year earlier in September to just over 21,000 vehicles. Through the first three quarters of the year, Toyota's green-car sales were down 9.1 percent to almost 247,000 vehicles. That still dwarfs any other automakers' green-car numbers. Toyota crossed the 6 million hybrid threshold in January when it doubled the 3 million total from March 2011. Toyota will start selling its first mass-produced hydrogen fuel-cell electric vehicle in Europe next summer, and hopes that it will repeat the long-term success that the Prius has enjoyed, according to Automotive News Europe.
