Description

[Detailed Description of the Invention] This invention provides a recording and
Regarding a trajectory display device having a playback function, the present invention aims to make it possible to easily distinguish between an outbound route and a return route, the current position, the direction of travel, and when to restart from a midway point.

That is, this invention displays coordinates and directions on the screen of a CRT (cathode ray tube), and uses information sent from auxiliary devices such as a direction sensor and a vehicle speed sensor, starting from a certain point within the coordinates. A device capable of displaying the trajectory of a vehicle on a screen, and further recording and reproducing the screen on a permanent recording device such as a cassette tape or floppy disk, in which the vehicle travels back and forth between a starting point and a destination. In some cases, the color of the outbound and inbound trajectories can be changed using the KEY or voice input, or the trajectory can be displayed as a solid line or a broken line, so that the current location of the vehicle can be easily determined. As a means for that purpose, this trajectory display device i includes a calculation device that calculates the current location relative to the departure point based on data obtained from the sensor, a memory that stores the current location that changes over time, and a memory that stores the current location that changes over time. It consists of a display device that displays trajectories based on the data obtained, and a permanent recording device such as magnetic or C-MOS that records these trajectories. This trajectory display device records the trajectory from the starting point to the halfway point in a permanent magnetic recording device, reads the trajectory data at any time desired, displays the trajectory on the display, and furthermore, the trajectory is reproduced on the display. From the end point, the trajectory and current location can be displayed again based on the data from the direction sensor and vehicle speed sensor. In this case, the trajectory can be continued from the middle to the destination, or the trajectory can be displayed from the beginning to the starting point. KE for each case when heading back towards the destination.
The color in which the locus is displayed can be changed by specifying it with Y or voice input. Furthermore, this trajectory display device reads the recorded trajectory screen from the memory and displays it on the display, and by specifying the starting point or any position on the trajectory, the color or brightness of the trajectory differs from the recorded and reproduced screen. With this configuration, which allows the trajectory to be displayed overlaid on the trajectory screen that is pre-displayed in color or brightness, this trajectory display device simply uses information from input devices such as a direction sensor or vehicle speed sensor. In addition to displaying the trajectory or current position (by specifying with the KEY or voice input, the trajectory can be displayed in different colors for the outbound and return trips to clearly indicate the current location and direction of travel. .Also, after reproducing the trajectory recorded in advance on a permanent recording device using the KEY input, etc.
Even if you start from any point on the trajectory, you can compare it with the old trajectory by changing the color or brightness of the trajectory using a key input or the like, and furthermore, you can confirm your current position and direction of travel.

An embodiment of the invention is shown in FIGS. 1 to 5. First, in Fig. 1, numeral 1 indicates a direction and vehicle speed sensor, a 2-digit keyboard device, a 3-digit memory device that temporarily stores image data and program data, and 4 displays an image on a CRT screen based on the image data of the memory device 3. 5 is a permanent recording device such as a cassette tape recorder or floppy disk that can semi-permanently record the image displayed on the display device 4 and reproduce it on the display device 4; 6 is the device 1; Control units 5 to 5 are arithmetic units that control the input and output of data and perform arithmetic functions based on input data.

Fig. 2 shows an example of a trajectory on the screen of the display device 4 with point R as the starting point and point T as the destination, and Figs. It shows. In this figure, Y represents YES and N represents NO in the flowchart. first,
By a predetermined operation at the starting point R, which is the reference point,
The arithmetic unit 6 is caused to jump to the routine shown in FIG. 3 in the locus mode (@FIG. 3). When the "outward route" key is input using the keyboard device 2, the process 8 shown in FIG. Based on this, the current position relative to the starting point R is calculated, stored in the memory 3, and changed over time, and at the same time, the trajectory is displayed on the display device 4 based on the data stored in the memory 3. The color of the locus at this time is set to "red", for example. In this way, point R and point T
When we reached point U in the middle of (Fig. 2 (!l)),
The trajectories between points R and U will be connected in "red" (
"Red" is indicated by a solid line). When the vehicle takes a break at this point U, in order to record the trajectory so far before stopping the engine and turning off the power, press the stop (STP) key and the record key on the keyboard 2 to record the 5th point. The contents of the memory 3 are recorded in the recording device 5 by processing 11 through judgments 9 and 1o in the figure. After stopping the engine and resting for a while, you can turn on the power and press the playback key on keyboard 2 to replay the same trajectory on the display. After Jin's regeneration is complete, if you want to continue the trajectory toward point T, press the "outward" key again (6
) Judgment 13 in Figure 4. Through the connector C, a "red" trajectory can be drawn continuously on the reproduced trajectory (FIG. 2(b)), and the trajectory is displayed as the vehicle travels to the destination T.

On the other hand, when returning to the starting point R from point U on the way, by operating the playback key (Fig. 3) on the keyboard 2 and inputting the "return" key, the yellow color is determined by judgment 14 and process 15 in Fig. 4. As the vehicle travels, the trajectory is displayed as shown in FIG. 2(C) (represented by a dotted line). In this case, as shown in FIG. 2(C), in the portion where the outbound trajectory (red) and the return trajectory (yellow) overlap, the "red" color of the outbound trajectory is changed to "yellow" (indicated by a dotted line). In addition, in the case of non-overlapping displays, as shown in Figure 2 (d), the "
Both the "red" trajectory and the return "yellow" trajectory are displayed. When returning to the starting point R, press the stop (STP) key and connect connector E9 in FIG. 5 based on judgment 16 in FIG. 4.
A trajectory is recorded through the decision lO. When returning from destination T, perform the same operation as above to return to Figure 2 (e).
) A yellow return trajectory is drawn.

In addition, as shown in FIG. 2(f), if the trajectory between points R and T that has been recorded once is played back on the display device 4 and the trajectory is started from an arbitrary point Q between R and T, the keyboard device 2 After the position of point Q is stored in the memory by operation, by inputting the "return" key (FIG. 4), a return route can be drawn using a yellow route.

Judgments 17 and 18 in Figure 5 are when the vehicle stops traveling during the outbound or return trip, operates the stop key, and then restarts by operating the outward or return key without operating the record key. Judgments 19 to 23 are judgment parts for determining whether the image of the display device 4 is cleared by operating the clear (CLR) key.

As described above, the trajectory display device having the recording/reproducing function of the present invention is capable of distinguishing between displaying the outgoing trajectory and the returning trajectory, and also recording and reproducing the trajectory. This has the effect of being able to clearly display the driving platform of the vehicle, such as the direction of travel.
