A database for a set of orientation-matched road (OMR) sections is searched according to a calculated orientation of an object and orientations of road sections stored in the database. The OMR sections are searched for a position-matched road (PMR) set acc...

Disclosed is a traveling state determining device including an acceleration sensor which detects an acceleration, a cycle comparing unit which compares a varying cycle of an acceleration of a vertical direction component in an output of the acceleration se...

In one embodiment, a method comprises generating three-dimensional (3D) imaging data for an environment using an imaging sensor, extracting an extracted plane from the 3D imaging data, and estimating an uncertainty of an attribute associated with the extra...

The method involves determining an effective distance between a current position of an aircraft and a particular flying point. Aircraft deceleration and acceleration times are determined from respective convergence curves. The curves are different and form...

A velocity information acquisition section 21 acquires velocity information on the velocity of a vehicle and records this acquired information in a velocity information recording section 27. A state judgment section 23 judges start and stop states of the v...
