MOBILE-BODY POSITION DETECTING APPARATUS AND MOBILE-BODY POSITION DETECTING METHOD

摘要

An apparatus of detecting a position of a mobile body acquires a current position based on a result of accumulating heading directions and movement distances of the mobile body, acquires a modified current position acquired from modification by verifying a movement locus of the mobile body with a road shape, and compares the current position with the modified current position, thereby assigning a reliability degree to the modified current position. Alternatively, the apparatus acquires a current position based on a result of accumulating heading directions and movement distances of the mobile body, and compares the current position with a positioning result acquired based positioning satellites, thereby assigning a reliability degree to the current position.
