要求を自動的に行うことができる。After reaching a certain distance, a request can be automatically made to rotate the map by the difference between the currently displayed map orientation and the current orientation in which the vehicle is currently traveling straight.
（実施例）

結果を表示制御手段６におくる。In FIG. 1, reference numeral 10 denotes straight-line detection means, which is connected to rotation unit detection means 5 and straight-line distance calculation storage means 11. Reference numeral 12 denotes a rotation request determining means for issuing a rotation request, which receives the output from the straight distance calculation storage means 11 and sends the determination result to the display control means 6.

わない利点がある。Direction data is input from the direction detection means 1 in FIG. 1 to the rotation angle calculation means 4. In this rotation angle calculation means 4,
Difference between previous orientation data and current orientation data (rotation angle)
seek. In the rotation unit detection means 5, the rotation angle calculation means 4
It is detected whether the rotation angle obtained is larger than a predetermined value (for example, 5.6"). If the rotation angle is larger than the predetermined value, the direction data is transferred from the direction detection means 1 to the straight-ahead detection means 10. The vehicle speed detection means 10 detects whether or not the direction per unit time is changing (whether the vehicle is traveling straight or not).If it is determined that the vehicle is traveling straight, the vehicle speed detection means 2 Vehicle speed data is input to the straight-ahead distance calculation storage means 11, and the straight-ahead distance is calculated.When the straight-ahead movement continues for a predetermined distance, a rotation request signal is output from the rotation request determination means 12 to the display control means 6, and one display data rotation is performed. The display map is rotated by the control signal from the means 9. In this way, according to the above embodiment, the straight-ahead detection means 10 detects straight-ahead travel, and if there is no straight-ahead travel for a certain distance, issues a map rotation request. This has the advantage that the map does not rotate while the angle of the car is changing.

This has the effect of displaying the current position and direction more clearly.
