Abstract

PURPOSE:To prevent the user from losing the sight of the mark for the present position displayed on a display by emitting an alarm when said mark deviates from the predetermined region on the image plane of the display. CONSTITUTION:A control circuit 10 knows the preent position from an origin 5 from the signal detected with an azimuth detector 2 and the traveling distance detected with a detector 1 for traveling distance. A traveling locus 6 up to the present position and a mark 7 for the present position are displayed on a display 3. At such a time when the vehicle travels beyond a boundary line 8 and deviates from the predetermined region if the vehicle advances in the same direction of the mark 7 displayed on the display 3, the circuit 10 triggers a buzzer 9 to produce alarming sounds for a prescribed time, thereby announcing the possible deviation to the user. Then, the user is prevented from losing the sight of the present position.

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a travel trajectory display device that displays the travel trajectory of a vehicle such as an automobile on a display device capable of two-dimensional display, such as a CRT display.

This type of conventional device uses a distance detector such as an electromagnetic pickup and a direction detector using a magnetic sensor to convert the distance traveled and heading into electrical signals, and a control circuit using a microcomputer or the like converts these signals into electric signals. There are devices that process and calculate signals and display the driving trajectory and current position on a display such as a CRT. You can also check your current driving position by comparing it with a map.

In such conventional devices, when the display point indicating the vehicle's current position displayed on the display screen approaches the edge of the screen, and the user notices this, the current position is displayed by, for example, an attached operation switch. The procedure is to return the point to a predetermined reference point and then restart calculation and display of the travel trajectory from this reference point.

However, the display point indicating the current position is getting closer to the edge of the screen.
Even if the user finally deviates from the screen, if the user still does not notice this, he or she will subsequently lose track of the current position, and it will no longer be possible to compare it with the map, and the user will again be able to move away from the predetermined reference point as described above. A problem arises in that it becomes impossible to calculate and display the travel trajectory of the vehicle.
