Abstract

PURPOSE:To facilitate the recognision of running data, by displaying the running locus and the present position of a vehicle on a specialized running locus display, and displaying the advancing direction on a specialized bearing display. CONSTITUTION:A running distance detector 1 detects the running distance of a vehicle. A bearing detector 2 detects the advancing bearing of the vehicle. Two dimensional coordinate axes comprising an X axis 3a and a Y axis 3b are displayed on the screen of a running locus display 3. A running locus 3d of the vehicle from an original point O of the coordinate axes to the present position 3c is displayed on the screen. An advancing bearing display 4 displays the advancing direction of the vehicle by a pointer 4a. A control circuit 5 computes the running locus of the vehicle from the original point of the two dimensional coordinate axes to the present position based on the detected signals from the running distance detector 1 and the bearing detector 2 and displays and controls the result on the screen of the display 3. The circuit 5 also display and controls the advancing direction on the display 4. A reset switch 5a gives a command for returning the present position mark 3c to the original point O.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a travel information display device that displays the travel trajectory and heading of a vehicle such as an automobile.

In other words, the present invention is capable of displaying a driving trajectory that allows the driver to know the current location and the route taken by the vehicle he or she is driving, even in areas where the roads are unfamiliar. It is an object of the present invention to provide a driving information display device that can easily read the traveling direction of a vehicle.

In order to achieve the above object, in the travel information display device of the present invention, two-dimensional coordinate axes are drawn on the screen of a travel distance detector that detects the travel distance of the vehicle and a direction detector that detects the traveling direction of the vehicle. A travel trajectory indicator that displays the travel trajectory of the vehicle from the origin of the coordinate axis to the current position, a direction indicator that displays the traveling direction of the vehicle, and a detection signal of the travel distance detector and a detection signal of the direction detector. a control circuit that calculates the traveling trajectory of the vehicle from the origin of the two-dimensional coordinate axes to the current position based on the signal and controls the display on the screen of the above-mentioned display device, and controls the display of the traveling direction on the above-mentioned direction display. It is a % mark of preparation.

a mileage detector (2) that synchronously generates a pulse train signal;
) is, for example, a direction detector that detects the vehicle's traveling direction using a geomagnetic detection sensor, (81 is the origin of the coordinate axis, where a two-dimensional coordinate axis consisting of the orthogonal coordinate axes It is a traveling trajectory display device that displays the traveling trajectory (6d) of the vehicle from 0 to the current position (3C). It is made of a CRT, for example, and is arranged such that the scale of each axis is 10 and -. , (4) is a heading indicator that displays the heading of the vehicle, and has a scale with abbreviations N, S, E, and W indicating the heading, and the heading is indicated by the pointer (4a). .

Therefore, (5) is based on the detection signal of the mileage detector (1) and the detection signal of the direction detector (2), and the vehicle travel trajectory (3d
) and controls the display on the screen of the display (81), as well as displaying the heading on the direction display (4). Note that (5a) Fi is the reset switch of this control circuit. be.

In the above-mentioned display, the control circuit (5) displays and controls the current position of the vehicle in the following manner. By integrating the distance am, which is the detection signal of the control distance detection story (1), the two-dimensional coordinates (X, Y), that is,
Calculate d s to find the current position from the origin 0, and record the travel trajectory to the current position (3d) and current position mark (6c)
is displayed on the screen of the display device (8). As a result, the user can refer to the coordinate axes (6a), (3b) and the origin (0) to know the running trajectory (3d) and the boundary positions #, , (3c).

On the other hand, the user arbitrarily operates the reset switch (5a) to give a reset command to the control circuit (5),
The user (1) can clear the travel trajectory (3d) on the display (8) and return the current position mark (3c) to the origin point. Operate and run with the bamboo bamboo II
It is easy to confirm the current location by comparing the IIL trace (3a) and the boundary location marker (3c) with the map.

Further, the control circuit (5) displays the azimuth angle θ, which is the detection signal of the azimuth detector (2), using the azimuth indicator (sword pointer (4a). In other words, the direction indicated by the pointer (4) in Figure 1) This shows that the vehicle is traveling in the northeast direction.

In this way, since the traveling direction is displayed on the dedicated direction display (41), it is easy to get distracted by the direction.

As explained above, according to the present invention, the traveling trajectory (6d)
And the current position mark (5c) is a dedicated travel trajectory display! #(
In a+, the traveling direction is similarly displayed on the dedicated direction display (4), and is displayed in a display form that matches the nature of each piece of information, which has the effect of making it easier to calculate the km of this traveling information.
