US Patent 7765057 Driving schedule creating device

A redundancy computing part 22 computes a redundancy between respective detectable regions D of perimeter monitoring sensors 10 mounted in a plurality of vehicles, while a driving schedule creating part 26 creates such a driving schedule as to lower the redundancy between detectable regions D computed by the redundancy computing part 22, thus making it possible to create a driving schedule which reduces parts where the respective detectable regions D of the perimeter monitoring sensors 10 of the vehicles overlap, thereby increasing areas where obstacles can directly be detected by the perimeter monitoring sensors 10 of the vehicles.
