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.
