Mercedes Digital Light puts a light show on the road

Soon full-featured heads up displays, augmented reality, and intelligent lighting will all work together to provide drivers with the safest and most complete picture of the road ahead. Until then, it's one advance at a time, the latest being Digital Light for Mercedes-Maybach customers. Stuttgart engineers designed a small LED with more than a million micro-reflectors for each headlight. Hardware and software control the light pattern, and paint at least nine different graphics on the road in light to warn of safety issues ahead. Digital Light evolved from the intelligent headlights demonstrated on the Mercedes Experimental Safety Vehicle in 2009 — the same ESF2009 that previewed rear belt-bag inflating seatbelts. Back then, the main beams were composed of 100 LEDs, and a brain controlled each LED to create a specific and occasionally complex lighting pattern. The new Digital Light works with all the cameras, sensors, and navigation information employed by an S-Class, and has increased resolution 10,000-fold to roughly HD quality, with a commensurate rise in the complexity of available patterns and representations. Mercedes cites numerous benefits, one being a "virtually dazzle-free main beam," another being high beams that can selectively darken so as not to blind oncoming traffic or pedestrians. Some of the projected symbols include guide lines on the road representing the width of the sedan when navigating a narrow construction zone, an arrow pointing to a pedestrian either in or very near the road, a snowflake when the temperature drops below freezing, and a chevron placed on the center line or shoulder to warn a driver when he's leaving his lane or when there's someone in his blind spot. Digital Light will first go into service with selective fleet customers for the Mercedes-Maybach S-Class this year. Considering the state of current U.S. auto regulations, we wouldn't expect to see it here for a number of years.

Why we can't have better headlights here in the U.S.

It wouldn't be a European auto show if we weren't teased with at least one mainstream vehicle we can't have here. At the Geneva Motor Show last week, the small but vocal contingent of shooting-brake buffs lamented that the Mazda6 wagon won't be coming to our shores, although they can take comfort in the fact that the vehicle won't get the torquey 250-horsepower 2.5-liter turbocharged gasoline engine we'll get here. Mercedes-Benz also announced a new headlight technology in Geneva that likely won't be available here anytime soon. It's just the latest in a long line of innovative and potentially lifesaving front-lighting solutions that the federal government doesn't allow in this country due to outdated standards — and a current lack of leadership at the U.S. Department of Transportation. Mercedes-Benz's new Digital Light system that debuted in Geneva uses a computer chip to activate more than a million micro-reflectors to better illuminate the road ahead. The Digital Light headlamps works with the vehicle's cameras, sensors and navigation mapping to adjust lighting for the given location and situation and to detect other road users. The Digital Light technology also serves as an extended head-up display of sorts by projecting symbols on the pavement ahead to alert drivers to, say, slippery conditions or pedestrians in the road. And it can even project lines on the road in a construction zone or through tight curves to show the driver the correct path. Digital Light will be available on Mercedes-Maybach vehicles later this year, although like any technology it's bound to trickle down to less expensive vehicles. That is, if we ever get it here in the U.S. Audi, a leader in automotive lighting, has repeatedly run into snags trying to bring state-of-the-art car headlights to the U.S. The German luxury automaker's recently introduced matrix laser headlight system, which performs many of the same trick as Mercedes-Benz's Digital Light, also isn't legal on U.S. roads. And five years after the introduction of its matrix-beam LED lighting, which illuminates more of the road without blinding oncoming motorists with brights by simultaneously operating high and low beams, Audi still can't bring that technology to the U.S. either.

Recharge Wrap-up: Houston's bus revival, autonomous trucks on the Autobahn

A documentary shows how Houston, Texas significantly improved its outdated bus system. Called High Frequency: Why Houston is Back on the Bus, the short film describes how the city reimagined its bus system to become more efficient, more useful and more popular. Despite some opposition, the change has proven to be effective, with bus ridership up eight percent in three months, and light rail ridership up due to complementary bus routes. See the video above, and read more at CityLab. Automakers sent autonomous semi trucks on the German Autobahn as part of the European Truck Platooning Challenge of 2016. Mercedes-Benz, Volvo and Scania, among other groups, sent platoons of trucks between Stuttgart, Germany, and Rotterdam, Holland. In Mercedes's platoon of three trucks, the lead truck was fitted with lasers and other sensors to guide the convoy down the road. The two following trucks relied on vehicle-to-vehicle communication to trail 50 feet behind the lead, making room for cars to come between them and closing the gaps when able. The close following distance provides fuel economy gains of up to 10 percent in the rearward trucks on account of the reduction in drag. Read more at Hybrid Cars. Renault has reduced NOx emissions in its Euro 6b diesel vehicles in real world driving conditions. By improving its exhaust gas recirculation systems and NOx traps, nitrogen oxide emissions are cut in half on average, under certain driving conditions. The improvements will be included in vehicles leaving the factory beginning in July of 2016. Beginning in October, owners of Renault Euro 6b diesels can have the modifications added to their cars for free. Read more from Renault. Tata Technologies is creating an innovation lab in California to partner with EV technology companies. Having a tech center in California allows Tata to work on technologies that will largely be deployed in the company's main market of Asia. "Today, we are partnering with companies and startups who have aspirations to sell in China, but a lot of what they do is in California," says Samir Yajnik of Tata Technologies.

RideCell provides technology for services such as carsharing, ridesharing and other transit services. "The convergence of transportation trends in cities is of key importance to BMW," says Ulrich Quay, head of BMW i Ventures.
