NIST develops prototype meter test for hydrogen refueling stations

July 22, 2014 2:20 pm | News | Comments

Three automakers plan to begin selling hydrogen-fueled vehicles to consumers in 2015. To support the fair sale of gaseous hydrogen as a vehicle fuel, researchers at NIST have developed a prototype field test standard to test the accuracy of hydrogen fuel dispensers. Once the standard is field tested, it will serve as a model for constructing similar devices for state weights and measures inspectors to use.

Driverless car test site gets industry partners

May 6, 2014 10:21 am | by David Runk, Associated Press | News | Comments

General Motors, Ford and Toyota are joining the Univ. of Michigan in establishing a testing site for driverless cars that will simulate a cityscape, and will work with the school to help make such vehicles commercially viable, officials announced Tuesday. The Michigan Mobility Transformation Center's 32-acre testing site near the Ann Arbor school's North Campus is scheduled to be completed this fall.

Nissan develops first "self-cleaning" car prototype

April 28, 2014 11:00 am | Videos | Comments

Washing a car can be a costly and time-consuming chore. The European model of Nissan’s Note will be the first car to wear a new type of paint which could make car washes obsolete. The paint has been engineered to be super-hydrophobic and oleophobic, meaning it repels both water and oils. The tests may result in an aftermarket application.

Google: Driverless cars are mastering city streets

April 28, 2014 10:48 am | by Justin Pritchard, Associated Press | News | Comments

Self-driving cars are motoring along: Google’s cars can navigate freeways comfortably, albeit with a driver ready to take control. But city driving has been a far greater challenge for the cars' computers. In a blog entry posted April 28, the project’s leader said test cars now can handle thousands of urban situations that would have stumped them a year or two ago.

Tesla delivers first China cars, plans expansion

April 22, 2014 11:19 am | by Joe McDonald, AP Business Writer | News | Comments

Tesla Motors Inc. delivered its first eight electric sedans to customers in China on Tuesday and CEO Elon Musk said the company will build a nationwide network of charging stations and service centers as fast as it can. Customers received the first Model S sedans this week at a brief ceremony at Tesla's office in a Beijing industrial park, also the site of its first Chinese charging station.

Oak Ridge study pegs fuel economy costs of common practices

April 9, 2014 3:07 pm | News | Comments

People who pack their cars and drive like Clark Griswold in National Lampoon’s “Vacation” pay a steep penalty when it comes to fuel economy, according to a report by Oak Ridge National Laboratory. Researchers tested vehicles at a variety of speeds with different configurations of load and tire inflation. While the findings were not unexpected, they serve as a reminder of how drivers can save money by taking simple measures.

Advanced warning systems increase safety at intersections, study shows

April 9, 2014 9:28 am | News | Comments

A major factor making driving difficult is hazards that are sudden and hard to predict. The wrong choice in this situation, known as the “dilemma zone,” may lead to crashes. Roadside and in-vehicle display warning systems may help drivers handle these hazards by predicting their occurrence and providing advanced warning to the driver, according to a new study.

Hybrid vehicles more fuel efficient in India, China than in U.S.

March 31, 2014 4:14 pm | News | Comments

What makes cities in India and China so frustrating to drive in makes them ideal for saving fuel with hybrid vehicles, according to new research by scientists at Lawrence Berkeley National Laboratory. Heavy traffic, aggressive driving style and few freeways allow hybrids in these countries to deliver as much as a 50% increase in fuel savings over conventional internal combustion vehicles.

Emotion detectors could make driving safer

March 14, 2014 10:46 am | News | Comments

Technology now allows us to read facial expressions and identify which of the seven universal emotions a person is feeling: fear, anger, joy, sadness, disgust, surprise or suspicion. This is very useful in video game development, medicine, marketing and, perhaps less obviously, in driver safety. Scientists and automakers are now using these tools and embedded cameras to observe drivers and determine when driver irritation takes place.

California pushes to finish driverless car rules

March 12, 2014 1:44 pm | by Justin Pritchard, Associated Press | News | Comments

Once the stuff of science fiction, driverless cars could be commercially available by decade's end. Under a California law passed in 2012, the DMV must decide by the end of this year how to integrate the autonomous vehicles onto public roads. That means the regulation's writers will post draft language regulations around June, then alter the rules in response to public comment by fall in order to get them finalized by the end of 2014.

Interactive simulator takes driver behavior into account

March 10, 2014 7:43 am | News | Comments

Driving behavior is a key factor that is often insufficiently accounted for in computational models that gauge the dynamic characteristics of vehicles. Researchers in Germany have developed a new driving simulator designed to make the “human factor“ more calculable for vehicle engineers.

New special air filter blocks small particles from getting inside cars

February 25, 2014 9:31 am | News | Comments

While taking in the scenery during long road trips, passengers also may be taking in potentially harmful ultrafine particles (UFPs) that come into the car through outdoor air vents. Closing the vents reduces UFPs, but causes exhaled carbon dioxide to build up. Now, scientists have developed a high-efficiency cabin air filter that could reduce UFP exposure by 93% and keep carbon dioxide levels low.

Car-to-car talk offers warning on collisions

February 4, 2014 1:33 pm | by Joan Lowy, Associated Press | News | Comments

Your car might see a deadly crash coming even if you don't, the government says, indicating it will require automakers to equip new vehicles with technology that lets cars warn each other if they're plunging toward peril. The action, still some years off, has "game-changing potential" to cut collisions, deaths and injuries, federal transportation officials said at a news conference Monday.

Silicon Valley sees shortage of EV charge stations

January 20, 2014 6:59 pm | News | Comments

Installation of electric vehicle charging ports at some companies has not kept pace with soaring demand, creating thorny etiquette issues in the workplace. The shortage has created incidents of "charge rage" among drivers, with vehicles being unplugged while charging. But adding chargers is expensive.

Research: “Sourcing hub” could help create more efficient supply chain

January 15, 2014 3:55 pm | by Phil Ciciora, Univ. of Illinois, Urbana-Champaign | News | Comments

According to Anupam Agrawal, a professor of business administration at the Univ. of Illinois, Urbana-Champaign, firms can manage their sourcing better by developing relationships not only with their suppliers but also with their suppliers’ suppliers. The lack of communication or collaboration between the big players at either end of the supply chain spectrum can prevent gains in efficiencies.

An unconventional car

November 19, 2013 9:06 am | by Marlene Cimons, National Science Foundation | News | Comments

A city car under development at Ohio State Univ. has no engine, no transmission and no differential. It weighs half as much as a conventional car and is powered by battery-power motors in each of its four wheels. But it needs help from a computer to stay stable and operating smoothly, which is why the research team is designing sophisticated algorithms for the vehicle's onboard computer.
