Panasonic details radar-based technology that can detect collisions in low light
Collision detection for cars? Yeah, scientists are on that. But whenever we read about concepts like this, the accompanying literature is often curiously light on details pertaining to real-life driving conditions; it's often unclear how well the tech will fare if you dredge it up on a foggy day, or in the middle of torrential storm. But in that press release you see down there, low visibility and poorly lit roads are all Panasonic wants to talk about. The company just unveiled its new crash-avoidance system, which, like other concepts we've seen, uses millimeter-wave radar technology to detect pedestrians and bicyclists. Since humans tend to reflect weaker radar signals than cars, Panasonic has designed a new pulse radar code sequence that allows pedestrians to leave a bigger footprint. It's so effective, the company claims, that it can detect bystanders up to 40 meters (131 feet) away, and will work at night and through rain, fog, snow and blinding sunlight. That all sounds promising, of course, but as with other concepts, it's not clear, when, exactly we'll see this system put to good use in the real world.
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.
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]
Volvo, Mercedes and Honda get tested for collision prevention, everybody's a winner
We've heard the marketing babble, and pondered the possibilities of a hands-free drive to work, but do those radar-based collision prevention technologies actually work? The British Motor Insurance Repair Research Centre Thatcham seems to think so. BMIRPCT took a long hard look at Volvo City Safety, Mercedes Distronic Plus and Honda CMBS, and decided the technologies will have a major impact on slow speed accidents -- which account for 75% of accidents as it is -- and should prevent more than 125,000 injuries a year in Britain alone, according to this research.
