    DARPA helps drones avoid mid-air collisions

    Some of the latest consumer drones, such as the DJI Phantom 4, come with an obstacle avoidance system. They're designed for stationary and slow-moving objects, however, like trees and cyclists, rather than aircraft ripping through the sky at 550mph. That poses a problem if we ever want manned and unmanned aircraft playing nicely in the sky. To help, the Defense Advanced Research Projects Agency (DARPA) is working on a new sense-and-avoid (SAA) system. The group recently conducted its first test flight, demonstrating that a shoebox-sized prototype can effectively detect and track a Cessna 172G aircraft approaching from different angles.

  • Authorities want collision avoidance tech to be a standard car feature

    A lot of automakers have been developing crash avoidance systems for years, but the technology hasn't made it to most vehicles' feature list yet. The National Transportation Safety Board wants to change that: in a report released today, the agency has recommended for collision avoidance tech to be a standard in cars and all other passengers and commercial vehicles. In addition, it's asking federal regulators (aka the National Highway Traffic Safety Administration) to test and rate the crash avoidance systems developed within the past 20 years. The suggestion's already facing opposition from the Alliance of Automobile Manufacturers, though. Its vice president, Gloria Bergquist, told AP that the tech should remain optional, so buyers can decide which driver assist product they want.

  • Toyota plans mid-decade launch of anti-collision system and self-driving cars

    In 2015, Toyota plans to make an advanced anti-collision system available to consumers, starting with Japan. The system uses sensors that watch for other cars, pedestrians and other obstacles and not only hits the brakes, but steers the vehicle to avoid hitting whatever is in its path. It gives the driver a chance to react first, bringing up a visual cue then setting off an audible alarm, before taking action on its own. Of course, that's just the start of Toyota's plans. By the end of the decade it hopes to roll out Automated Highway Driving Assist (AHDA), a self-driving platform developed with its research vehicle unveiled at CES. The platform is built around two core technologies: Cooperative-adaptive Cruise Control, which talks to other cars over a 700MHz wireless connection to keep a safe distance at all times, and Lane Trace Control, which uses millimeter wave radar and high resolution cameras to keep the vehicle in its lane. These technologies will be deployed in limited situations at first, with a trial on the Shuto Expressway near Tokyo beginning on October 15th. The goal here isn't to take complete control away from the driver, but focus on improving safety. For more details on both initiatives, check out the PR after the break.

  • GM demos accident avoidance system with brains and long range

    Collision avoidance systems aren't exactly exciting new news any more. But most of these systems, even the ones that jerk the wheel out of your hands, simply detect obstacles -- they don't talk to each other. GM's new prototype uses Dedicated Short-Range Communication (DSRC) to share data with other vehicles. The cars not only detect other motorists, but construction zones, police activity, and slowed or stopped traffic. Unlike a similar concept from Ford, GM doesn't just talk to cars in the immediate area, but can detect trouble up to a quarter mile down the road, offering plenty of warning time for you to change course or hit those breaks. We think the company's estimate that such a system could avoid 81-percent of crashes in the US is a tad optimistic though -- clearly they don't realize how big of jerks most drivers are.

  • Toyota's new crash-avoidance technology takes control of the wheel

    Crash-avoidance technology in cars is hardly anything new, of course, but Toyota's gone a bit further than most with its latest effort. While complete details are still a bit light (including any word of an actual rollout to vehicles), the new system is said to use a combination of both front and rear cameras, and millimeter wave radar technology to detect pedestrians or obstacles that could lead to a crash. The real kicker, however, is that when the car does detect a possible collision, it actually takes control of the wheel to avoid it instead of just stopping the vehicle. What's more, that's just one new safety measure that Toyota recently showed off to reporters in Tokyo -- it's also working on things like a pop-up hood that could provide some additional protection in the event of a crash, and a steering wheel that can measure the driver's heartbeat and avoid a crash if they suffer a heart attack.

  • Continental readies stereo camera system for 'seeing' cars

    The idea of cars preventing accidents before they happen isn't novel, but at the end of the day, collision detection systems are only as smart as the information being fed to them. That's the ethos behind Continental's new stereo camera system, which spots people, pets, and other objects in a vehicle's path, and measures their height, distance from the vehicle, and how they might be moving. This rig, which will be just another part of Continental's ContiGuard safety system, uses the difference in the lenses' optical paths to make these calculations -- so long as those obstacles are 20 to 30 meters (66 to 98 feet) away. The company also says the cameras are sharp enough to detect partially obscured objects, and claims accuracy within 20 to 30 centimeters (8 to 12 inches). No word on when it will be ready to ship seeing cars, though if the press release is any indication, German drivers are likely to get their test drive first.

  • Ford's intelligent vehicles communicate wirelessly, shoot hula hoops out of tailpipes (video)

    Imagine how many accidents could be avoided if we all had perfect X-Ray vision -- assuming, of course, that everyone could refrain from being distracted by all the naked pedestrians. Drivers would never be surprised by rapidly slowing traffic, cars broken down around blind curves, or autos zooming into blind spots. No matter how many ads we respond to in the back of Mad Magazine we'll never have that, but Ford has an alternative with its Intelligent Vehicle Research: cars that simply rely on GPS and a wireless data connection to beam their location and speed to each other. Autos alert their drivers when a car at the front of a convoy is rapidly decelerating or when there's a broken down rig right around the next bend. Interestingly the tech is using WiFi, not cellular data, so range is somewhat limited, but still far enough to warn drivers with blinking lights or trigger an automatic-braking system. It's all demonstrated in the video after the break and, while there are no crazy platooning stunts like Volvo recently showed off, we have to figure that's coming in version 2.0.

  • Nissan shows off two more collision avoidance prototypes

    Nissan has a knack for pumping out novel safety advancements every few months, and the latest two are in the same vein as a few previous efforts. Two new technologies, Side Collision Prevention and Back-up Collision Prevention, fit into the auto maker's Safety Shield concept to "help protect the vehicle and its occupants from potential risks coming from multiple directions." As for the first, the tech utilizes side-mounted sensors to activate a warning if an approaching vehicle is detected in the drivers intended lane; from there, a yaw mechanism is "activated through brake control of individual wheels to help prevent a potential collision." For the second, an array of sensors detect potential obstacles and triggers an alarm / puts on the brakes if a collision is about to happen. Per usual, there's no mention of when these brilliant ideas will be implemented into production vehicles, but our insurance bills are pleading for "soon." [Via Gizmag]
