Document Type and Number:
WIPO Patent Application WO/2014/196115
Kind Code:
A1
Abstract:
Provided is a device for determining whether a vehicle is stopped, adapted to accurately determine, from GPS information for a vehicle, whether the vehicle has stopped. This device (100) for determining whether a vehicle is stopped has: a low-speed interval extraction unit (120) for extracting a low-speed interval which is an interval extending from the location of the vehicle at a first point in time at which the measured speed of the vehicle, which speed is obtained from GPS information for the vehicle, has fallen below a prescribed value, to the location of the vehicle at a second point in time at which the measured speed has exceeded the prescribed value; a vehicle speed transition model generating unit (130) for generating a vehicle speed transition model having as conditions of constraint an interval distance indicating the length of the extracted low-speed interval, and the time elapsed from the first point in time to the second point in time, for indicating temporal transition of the speed in such a way that the speed continuously increases to the second point in time after having decreased from the first point in time; and a stop determination unit (140) for determining that the vehicle has stopped within the low-speed interval, on the condition that an interval in which the speed is zero or less is present within the generated vehicle speed transition model.
