As Toyota enhances the efficiency of its vehicles, included in improving them overall are advancements in their safety.   This week the company announced both a new high-speed collision avoidance system and a new testing facility in Japan to further develop pedestrian and related safety technologies as well as environmental and fuel-efficiency related innovations.   Pre-collision System: Intelligent Braking From Toyota  Toyota cites statistics from the Institute for Traffic Acci ...
Get into a cab and it’s safe to assume the driver knows the ins, outs, shortcuts and potential traffic tie-ups between you and your destination. That kind of knowledge comes from years of experience, and IBM is taking a similar tact that blends real-time data and historical information into a new breed of traffic prediction. IBM is testing the new traffic-management technology in a pilot program in Lyon, France, that’s designed to provide the city’s transportation engineers wit ...

University of California, San Diego researchers say they have developed a way to better estimate what goes on inside lithium ion batteries -- a breakthrough that could lead to lower battery costs and faster charging times for electric vehicles.   Professor Miroslav Krstic and postdoctoral fellow Scott Moura devised the algorithms, or mathematical procedures, to clarify what goes on in the "complicated world" of lithium ion batteries, Krstic said in an interview last week.   There is st ...
Car buyers and bureaucrats are demanding better fuel economy, so automakers are hellbent on squeezing every last MPG from a tank of gas. The byproduct of this is more fuel-sipping powertrains, but there’s an unintended consequence: more unwanted noise in the cabin.   “Things are happening with powertrains that are good for fuel efficiency, but not necessarily good for the noise character inside the vehicle’s cabin,” John Pelliccio, manager of Technical Product Market ...
  Nissan has created a new system to help reduce the likelihood of pedal misapplication. Called the Emergency Assist for Pedal Misapplication with Carpark Detection Function (catchy, huh?), the technology uses a version of the company's ingenious Around View monitor to detect if the vehicle is in a parking space. If so and there are solid object such as other vehicles or walls near by, the vehicle's cameras will automatically control acceleration and apply the brakes to prevent a collision ...
Engineers at the University of California, San Diego, have developed sophisticated estimation algorithms that allow lithium-ion batteries to run more efficiently.   This algorithms could potentially reduce lithium-ion batteries’ cost by 25 percent and allow the batteries to charge twice as fast as is currently possible.   In one instance, electric batteries could be charged in just 15 minutes.   The researchers at the Jacobs School of Engineering at UC San Diego are sharing ...
BMW is experimenting with infrared heating systems for future cars, warming occupants in a more fuel-efficient and precise manner, and thus potentially extending the range of hybrids and EVs. The system, outlined during a BMW “innovation day,” bypasses traditional warm-air vents in favor of infrared heating surfaces that warm passengers directly. There’d be no more sitting shivering until the car warmed up in the depths of winter, either, with BMW claiming that the system can h ...
The timeline for autonomous cars hitting the road en masse keeps getting closer. GM’s Cadillac division expects to produce partially autonomous cars at a large scale by 2015, and the automaker also predicts it will have fully autonomous cars available by the end of the decade. Audi and BMW have also shown self-driving car concepts, with the former working with Stanford to pilot a modified TT up Pikes Peak. Meanwhile, Google is ripping along at its own rapid pace with a fleet of fully auton ...
Engineering students at the University of Birmingham in the U.K. have successfully built and demonstrated a hydrogen-fuel-cell-powered locomotive.   In testing at the Stapleford Miniature Railway in Leicestershire, the hydrogen-powered narrow-gauge train managed to carry a load that weighed more than 8,800 pounds. ”The hydrogen system worked quietly, efficiently and reliably throughout two days of testing,” said project leader Stephen Kent. “The same could not be said for ...
Automakers say they will squeeze much more efficiency from the internal combustion engine.   For instance, they will use excess heat to warm engine lubricants more quickly to reduce friction. Better transmissions will reduce friction, and turbocharging and direct injection will boost power from small engines.   "We've got to have a lot of small improvements, like Olympic athletes, to get to the goals that we're looking for," Gary Rogers, CEO of engineering firm FEV Inc., said at the ...
In an effort to cut costs and boost efficiency, Ford is to introduce a complete virtual factory that will simulate the production process on the assembly line.   With thousands of components needed to construct a vehicle, it is believed that computer simulation will help with the testing of the vehicle build process without the need for investing in a real-world production line until it is ready. Indeed Ford has been using computer simulations since 1977 – the first carmaker to do so ...
A fleet of mini Minis will be used to retrieve javelins, hammer, discus and shot during the London 2012 Olympic and Paralympic games. See the car in action.     ...
Researchers at the Goodyear Tire & Rubber Company have found in their tests that using soybean oil in tires can potentially increase tread life by 10% and reduce the tiremaker’s use of petroleum-based oil by up to seven million gallons each year.   In addition, testing at Goodyear’s tire plant in Lawton, Oklahoma showed improved mixing capabilities in the manufacturing process. The company found that rubber compounds made with soybean oil blend more easily with the silica u ...
  Mercedes-Benz can be credited with more technological firsts in the automotive industry than perhaps any other company, but it cannot lay claim to being the first automaker to offer a seatbelt airbag. Nor can it claim to be the second. Those two spots go to the Ford Explorer and Lexus LFA, both of which came out with seatbelt airbags in 2010.   Nevertheless, Mercedes isn't the sort of company to let the glory of being first get in the way of doing something worthwhile, and so its ne ...
