1. An azimuth determination apparatus comprising:
- horizontal-direction acceleration detection means installed in a movable body as means for detecting an acceleration caused by a centrifugal force, which is generated when said movable body is making a turn, as an acceleration oriented in a horizontal direction perpendicular to the traveling direction of said movable body; and
azimuth determination means for producing a result of determination as to whether said movable body is making a right or left turn on the basis of said detected acceleration oriented in said horizontal direction and threshold values.

Abstract
Disclosed herein is an azimuth determination apparatus including: a horizontal-direction acceleration detection section installed in a movable body as a section configured to detect an acceleration caused by a centrifugal force, which is generated when said movable body is making a turn, as an acceleration oriented in a horizontal direction perpendicular to the traveling direction of said movable body. The apparatus further includes an azimuth determination section configured to produce a result of determination as to whether said movable body is making a right or left turn on the basis of said detected acceleration oriented in said horizontal direction and threshold values.
