New Sensor May Eliminate Blind Spots
Posted on October 2, 2007CNET reports that Micron is launching a new sensor, called MT9V023, that can be used to improve vehicle safety. CNET's article includes this list of possible uses for the in-camera camera.
There are lots of accidents caused by blind spots that could be avoided without them. The cameras mentioned above that monitor whether a vehicle is "unintentionally drifting out of a lane" could be used to wake a suddenly sleeping driver. These are just a few of the many uses for advanced cameras and sensors.
Volvo's XC90 SUV uses three cameras: one for backing up and two for monitoring the blind spots to either side of the car. Cameras can be used to check for vehicles that are destined for a collision, telling the car to deploy air bags or tighten seat belts. The Hyundai Move in Japan uses this application, he said. Another forward-looking camera can check if a driver is unintentionally drifting out of a lane, using an algorithm that factors in speed and how sharply the steering wheel is being turned to distinguish between unintentional drifting and deliberate lane changes. Yet another front-mounted camera could keep an eye out for oncoming night traffic, automatically switching headlights between dimmed and high beams. A camera mounted on top of the steering column can monitor the frequency and duration of a driver's blinks to guard against drowsy driving. If blinks become too rapid or protracted, the car can sound an alarm to jolt the driver awake. An internal camera can help identify passengers to control how air bags should be deployed--for example, with less force when protecting children. Another camera could let parents watch their children bicker in the distant reaches of a vast van or SUV.
