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, PSA extend partnership with new European van

Toyota and PSA Peugeot Citroen collaborate on a number of vehicles. One of them is a small van jointly developed by the two automakers but marketed individually under their own brands across Europe. Now they've announced the extension of that collaboration, and revealed the first image and details of their new product. Set to be unveiled at their respective booths at the Geneva Motor Show this coming March are the new Toyota ProAce, Peugeot Traveller, and Citroen Spacetourer. They replace the Toyota model of the same name as well as the outgoing Peugeot Expert and Citroen Dispatch, and will each be made available in private and commercial shuttle forms. Although technical specifications have yet to be announced, each will share the same underpinnings and mechanical components, leaving only the parts you can see changing from one brand's version to the next. Expect engines to range from 1.5 to 2.0 liters and burning gasoline or diesel, but the latter will undoubtedly prove the more popular option in Europe. No mention was made of a replacement for the Fiat Scudo, another badge-engineered version of the same van program in its current form. That would seem to suggest that Fiat Professional is either preparing to go it alone with the next-generation Scudo, or phase out the model altogether. The current Scudo slots in between the smaller Doblo (imported to the US as the Ram ProMaster City) and the larger Ducato which was also jointly developed with PSA and sold as the Citroen Jumper/Relay, Peugeot Boxer, and here in America as the Ram ProMaster. The ProAce and its cousins are made by PSA at its Sevel plant in Valenciennes, France. Aside from their vans, the Japanese and French automakers also collaborate on the city car platform sold alternately as the Toyota Aygo, Peugeot 108, and Citroen C1. Fiat also partners with PSA on the smaller Fiat Fiorino/Qubo, Peugeot Bipper and Citroen Nemo. All of which just goes to show what a tangled web they weave in the European market, especially where commercial vehicles are concerned. NEW STAGE IN THE CO-OPERATION PROGRAM BETWEEN PSA PEUGEOT CITROEN AND TOYOTA PSA Peugeot Citroen and Toyota Motor Europe (TME) reveal today the new Citroen SPACETOURER, Peugeot TRAVELLER, and Toyota PROACE. They will be available in MPV versions for private use and in shuttle versions for business use. Both companies therefore confirm the continuation of their co-operation agreement signed in 2012.

Toyota to buck engine downsizing trend, may go larger and turbo-free

Turbocharging isn't really Toyota's specialty, and the Japanese automaker isn't being shy about acknowledging it. Koei Saga, a senior managing officer in charge of drivetrain research and development, says that eschewing turbos and increasing displacement of engines using the Atkinson cycle can produce better power gains without sacrificing fuel economy, Automotive News reports.
Toyota is investing heavily in larger-displacement Atkinson-cycle engines in addition to turbocharged engines, but Saga doesn't think the automaker will use turbocharging across many product lines. He apparently remains unconvinced that the technology "makes the world better."
In Toyota's eyes then, Atkinson cycle engines do make the world better, and here's how. Their pistons complete four processes - intake, compression, power and exhaust - in one revolution of the crankshaft, and the power stroke is longer than the compression stroke. Traditional Otto cycle engines require two crankshaft revolutions to accomplish those same four operations and have equal-length compression and power strokes. Atkinson cycle engines are more efficient, but less power dense, though increasing displacement can offset that shortfall.
