Navigation apparatus for automotive.

摘要

A navigation apparatus mounted on a vehicle comprises a distance sensor (1) sensing the travelled distance of the vehicle, a direction sensor (2) sensing the advancing direction of the vehicle, an information storage unit (4) storing map data, a signal processor (3) computing the present position of the vehicle on the basis of the output signals from the distance sensor and direction sensor for displaying the computed present position of the vehicle on a color cathode-ray tube (503) together with a map read out from the information storage unit. In the navigation apparatus, the map data are provided by position coordinate information or font information of division points dividing a road map into sections that can be linearly interpolated.
