Volvo Car Corporation recently introduced an in-vehicle radar system that could detect the pedestrians coming in the line of vehicle movement. These researchers from Technical University of Munich have come up with a better pedestrian movement detector, capable of detecting cyclists and pedestrians even when they are not in front of them.
In the designed Ko-TAG system, the pedestrian/cyclist wear a small transponder. Car on the other hand sends a specially coded signal in the surrounding. When these signals come in contact with the transponder, the transponder responds and transmits back the coded signal to the vehicle, alerting him about the distance, position and trajectory of movement. If the system determines vehicle and person are about to collide it can alert the driver and or even apply the breaks automatically.
“With this, we achieved an accuracy in distance measurement of a few centimeters. Together with the unique code-based process, this is the explanation for the exceptional performance and an important unique selling point of our system,” says Professor Biebl. The clever design and techniques make the whole process happen in a few microseconds, with the precision of centimeters.
The small wearable transponders can also be integrated with cell phones in the future, with minor hardware modifications. One major cell phone manufacturer has already expressed interest in the system.
