Nearly 700,000 Toyotas and Lexuses named in fuel pump recall

In an announcement posted to its corporate press room, Toyota made known a voluntary safety recall on select 2018 and 2019 Toyota and Lexus models. The recall includes roughly 696,000 vehicles and deals with a fuel pump that might stop working. An internal investigation into the issue is under way.  Affected rides include the Toyota 4Runner, Camry, Highlander, Land Cruiser, Sequoia, Sienna, Tacoma, Avalon, Corolla, and Tundra, as well as the Lexus LS 500, LC 500, RC 350, RC 300, GS 350, IS 300, ES 350, LX 570, GX 460, RX 350 NX 300, RX 350L, and GS 300. The Avalon, Corolla, NX 300, RX 350L, and GS 300 are restricted to 2019 model years, while the others are 2018 and 2019 model years. The potential danger in this issue is pretty obvious. Should the fuel pump stop, the vehicles could sputter, stall, and come to a stop, likely without the ability to restart the cars. Toyota notes warning lights and messages would display should this occur, but by then, it'd be too late. Although Toyota made the announcement this week, the investigation is not yet complete, and therefore, a fix has not yet been specified. The resolution, when determined, will come free of charge to affected customers. Toyota plans to send out notifications for affected vehicles in mid-March. 

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

How Toyota's 100-year textile history influenced FCV hydrogen fuel cell car

Turns out, Toyota had a surprising ace in the hole when it came to building the new fuel tanks for the FCV hydrogen fuel cell car, which is coming next year. Well before Toyota became the Toyota Motor Company, it was the Toyota Industries Corporation and it made textile looms. This is important because the main structure of the hydrogen tank is wound carbon fiber. When Toyota set out to increase the strength of the tanks to hold hydrogen stored at 10,000 psi (up from 5,000 in the previous tanks), it was able to draw on its 100-year-old history as it designed its car of the future. "A lot of that textile experience came back when we did the tank wrapping." – Justin Ward "We have a lot of experience with textiles," Justin Ward told AutoblogGreen at the 21st World Congress on Intelligent Transport Systems (ITS) in Detroit this week, "and a lot of that textile experience came back when we did the tank wrapping." On top of being able to hold the higher-pressure hydrogen, Toyota's first attempt to build its own hydrogen tank was six times faster than the industry standard, so it saved time and money as well as working better. The company will also be able to inspect its own tanks. Ward is the general manager of powertrain system control at the Toyota Technical Center and hydrogen vehicles are something he knows a lot about. The reason for the stronger, 10,000-psi tanks is because the 5,000-psi tanks only offered around 180-200 miles of range, even with four tanks in the early $129,000 FCHV Highlander hydrogen prototypes. The FCV only has two, but they will able to deliver the 300-mile range that customers told Toyota they wanted. Dropping the number of tanks not only obviously reduced the cost for the tanks themselves but also the number of valves and hoses and other components you need. Despite the benefits of higher compression, going much higher doesn't make sense. 10,000 psi is the "natural progression," Ward said, because "you start to bump up against compression inefficiencies." Think of an air compressor. When hydrogen is produced at a wastewater treatment plant or a reforming site, Ward said, is it at around ambient pressure (14 psi). That has to be raised, using compressors, all the way to 10,000 psi. "That takes energy," Ward said, "and every doubling of pressure adds another doubling of energy needed, so it starts to add up pretty fast if you go too high." Component specifications are also fine at 10,00 psi, but more difficult at higher levels.
