RUNNING CONDITION DETECTION DEVICE, RUNNING CONDITION DETECTION METHOD, AND RECORDING MEDIUM

摘要

A running condition detection device includes
a GPS receiving unit configured to receive a GPS signal and output a current position,a geomagnetic sensor configured to detect geomagnetism,a direction determination unit configured to obtain a current moving direction based on current positional data and last positional data from the GPS receiving unit,a first bend determination unit configured to compare current moving direction data obtained by the direction determination unit and reference direction data to determine passage of a street corner,a second bend determination unit configured to compare geomagnetic data detected by the geomagnetic sensor and reference geomagnetic data to determine passage of a street corner, anda determination prohibition unit which prohibits the first and second bend determination units from determining passage of a street corner during a given period of time when passage of a street corner is determined by one of the first bend determination unit and the second bend determination unit.

1. A running condition detection device comprising:
a GPS receiving unit which receives a GPS signal and outputs a current position; a geomagnetic sensor which detects geomagnetism; a direction determination unit which obtains a current moving direction based on current positional data and last positional data from the GPS receiving unit; a first bend determination unit which compares current moving direction data obtained by the direction determination unit and reference direction data to determine passage of a street corner; a second bend determination unit which compares geomagnetic data detected by the geomagnetic sensor and reference geomagnetic data to determine passage of a street corner; and a determination control unit which prohibits the first and second bend determination units from determining passage of a street corner during a given period of time after passage of a street corner is determined by one of the first bend determination unit and the second bend determination unit, and to maintain determination of passage of a street corner by the first and second bend determination units when determination is not prohibited.
