Clear the memory area to write data from, and also
Initialize each output port. In step S1, a photocoupler (not shown) detects whether the information recording card 30 is present in the card drawer section 18 into which the information recording card 30 is inserted or removed.

In step S1, the information recording card 30 is placed in the card drawer section 1.8.
When it is determined that the card exists, the "card insertion operation" routine is called in step S2, and the processing of the routine shown in FIG. 11 begins.

In the "card insertion operation" routine, the information recording card 30 is pulled in in step S81, and data from the information recording card 30 is written in the storage means 6 in step 382.
The processing of steps S81 and S82 is continued until the information recording card 30 is pulled in at step 88B.

After exiting the "card insertion operation" routine, the registration switch 16 selects a routine for storing the future travel route in the storage means 6, or transfers various data from the information recording card 30 to the storage means 6 in step S3. , it is determined whether the guide switch air, which outputs the positioning data stored in the storage means 6 to the display unit 4 and selects the navigation mode, is on, and when the registration switch 16 and the guide switch air are off, the process starts from step S1. The routine of step S3 is repeatedly executed.

When the registration switch 16 or the guide switch 17 is on, it is determined in step S4 whether the power switch 19 is off,
When the power switch 19 is turned off to end the use of this automobile route guide device, step S5
The ``card ejection operation'' routine is called, and the processing of the routine shown in FIG. 12 begins.

Normally, when the power switch 19 is turned on and the processing of this main program is started, it is confirmed in step S4 that the power switch 19 is on, and in step S6 it is determined whether the GPS receiver 2 is performing positioning, and the positioning is performed. If not, the routine starts from step 81B.

When it is determined in step S6 that the GPS receiver 2 is performing positioning, the current positioning position is calculated in step S7, and it is determined in step S8 whether it is the timing to store the positioning data,
If it is not the timing to store the positioning data, step 813

In step 823, from the positioning data stored in address n and address n+1, the positioning data of the passed position and the positioning data of the next arriving position are compared, and the next arriving position seen from the passed position is determined. The direction of the position and the direction of the next positioning position to arrive from the current positioning position are calculated.

In step S24, the positioning data of the positioning position passed through is compared with the positioning data of the next positioning position, and the straight-line distance d from the current positioning position is calculated.

Note that at this time, it is also possible to calculate the straight-line distance to the starting point. In step S25, the straight line distance d to the positioning position is
and a predetermined distance La for starting the lighting display, and if the straight-line distance d to the positioning position is not within the predetermined distance La, in step S26, the distance to the current positioning position on the display operation panel 10 is displayed on the distance display section 4A. indicate. Further, the direction of the next position from the current position around the distance display section 4A is displayed on the own vehicle traveling direction display section 4B. The guidance direction display section 4C displays the direction of the next positioning position seen from the positioning position passed, that is, the direction in which the own vehicle should proceed, by continuously lighting up. In addition, a predetermined comment is continuously displayed on the character display section 4D. This display state is determined in step S25 by the straight line distance d from the positioning position.
This is obtained by performing the routine processing from step S24 to step S26 and step 526a until the distance is within the predetermined distance La. If it is determined in step 526a that the straight line distance d to the positioning position is less than a predetermined distance, and that the direction in which the own vehicle should proceed is biased by a predetermined angular amount, an alarm will be sounded in step 526b. to notify you that you are away from the road.

The distance is displayed on the distance display section 4A. Further, the direction of the next position from the current position around the distance display section 4A is displayed on the own vehicle traveling direction display section 4B. The guidance direction display section 4C displays the direction of the next positioning position seen from the positioning position passed, that is, the direction in which the own vehicle should proceed, by continuously lighting up. In addition, a predetermined comment is continuously displayed on the character display section 4D. This display state is shown in step S35.

When it is determined in step S71 that the cursor switch 13 is on, a writing position is specified in step 87B to designate a position where a character to be written has not yet been determined so that writing is performed sequentially from the left side of the character display section 4D. . Step S7
In step 4, alphabets, katakana, numbers, etc. are repeatedly rotated, and in step 875, when a specific character is selected from among the alphabets, katakana, numbers, etc., and the character power switch 14 is turned on, the character switch 14 is turned on. Before writing a character at the designated position in S76 and using 8 digits in step S77, it is determined whether the writing of the character has been completed in the middle, and the elapse of the time T1 used for writing is determined. In step 878, it is determined whether 8 digits have been written in the character display section 4D. Step S
When it is determined in step S77 that the time is within time T1 and that writing of the 8 digits in the character display section 4D has not been completed in step S78, the routine processing from step 87B is repeatedly executed. Further, when it is determined in step S77 that the time T1 has elapsed, or when it is determined in step S78 that writing of the 8 digits on the character display section 4D is completed, the address counter n=0 of the selected memory area is set in step S79. Write it down.

That is, in this routine, alphabets, katakana, numbers, etc. are repeatedly rotated by the cursor switch 13, and by turning on the character manual switch 14, characters are written in order from the left of the character display section 4D.
When the time TI is exceeded, or when writing of 8 digits on the character display section 4D is completed, it is written to the address counter n=o of the selected memory area.

That is, in the routine of "positioning data storage operation" of this embodiment, the operation will be explained using the diagram of FIG.

As shown in FIG. 13(a), in the routine from step S54 to step S55 and step S60, from the starting point to the final destination, from address 1 to address m of the maximum address value of address area AD, which is sequentially allocated, , positioning data D1 to Dm are sequentially stored in the positioning data storage area DA.

Then, in the case of writing the next positioning data in which positioning data Dm has been stored up to address m, in the routine from step S55 to step S59, first, step S56
The address counter n is set to 12'', the positioning data of address 2 is cleared, and the positioning data of address 3 is stored in the empty positioning data memory area of address 2 in step S57, as shown in FIG. The subsequent addresses are moved by "1" address. Then, as shown in FIG. 13(C), the positioning data of address 2 and subsequent positions are repeated, and the positioning data of the current positioning m+1 times 1 is stored in the positioning data memory area of address m that is now empty in step S59. Store data at address m. Similarly, next time, as shown in FIG. 13(d), the current positioning data for the twelfth time is stored in the positioning data memory area at address m at address m. Furthermore, if necessary, a comment is stored in the comment storage area CA corresponding to the positioning data in the positioning data storage area DA measured using the positioning satellite 7 and stored sequentially from the starting point to the final destination.

The positioning data stored in the storage means 6 is as shown in FIG. 14, which is an explanatory diagram of the contents of the positioning data of the automobile route guide device according to the embodiment of the present invention.

That is, the one closest to the starting point among address 1, address 2, address 3, address 4, ..., address m-2, address m-1, address m1, address m+1, address m + 2, ... Even-numbered addresses are thinned out from the positioning data, and the positioning data closer to the starting point has a density that is half the density of the positioning data closer to the final destination.

Thereby, even if the storage capacity of the storage means 6 exceeds the storage capacity, information on the measured position of the road on which the vehicle is traveling can be stored.

However, the user of the automobile route guide device of this embodiment, that is, the general user, often knows the location near the starting point based on his/her driving experience, but the geography of the location near the final destination is unknown. Therefore, it is possible to increase the density of positioning data closer to the final destination to provide detailed information to the user.

After controlling in this manner, when the use of the automobile route guide device of this embodiment is finished, the "card ejecting operation" routine is called by the steering knob S5 by turning off the power switch 19 of the steering knob S4, and 12, first, in step S91, the ejection of the information recording card 30 is started, and in step S92, it is determined whether three write switches 12 are on, and when the write switch 12 is on, Step 89
At step B, it is determined whether a write-protection section 33 that prohibits writing is formed in the card body 31 of the information recording card 30, and if the write-protection section 33 is not formed, the data up to that point is deleted at step S94. New data is written while clearing the magnetic band 32 regardless of the presence or absence of writing, and the routine processing from step S91 to step S95 is repeated until the ejection of the information recording card 30 is confirmed in step 5-95, and the information is recorded. When it is confirmed that the card 30 has been ejected, the power is turned off in step S95 to terminate the main program. Further, when it is determined in step S92 or step 893 that the write switch 12 is off, and when it is determined that the write-protection section 33 that prohibits writing is formed in the card body 31 of the information recording card 30, the information Steps S91 to S are performed without writing to the card body 31 of the recording card 30.
92 or repeat the routine processing of step 893,
When it is confirmed that the information recording card 30 has been ejected, the power is turned off in step S95 to terminate this main program.

Note that, as can be determined from this example, the calculation means 3
Since the storage timing of the positioning data is determined by the setting of the built-in timer, by changing the time limit setting of the timing with the timing changeover switch 15, the drive distance corresponding to the memory can be set for long distance or short distance. can do. Further, on a complicated road, the time limit of the timer may be shortened during the outbound trip so that detailed road information can be obtained.

Conversely, on well-known roads, the timer setting built into the calculation means 3 may be stopped, and the current position registration switch 20 may be used to store positioning data only at specific locations, such as at every interchange or predetermined rest stop.

In this embodiment, when driving toward a specific destination, the positioning data of the own vehicle's position is stored in the information recording card 30 at predetermined time intervals using the positioning satellite 7, and the data is stored in the information recording card 30 at predetermined time intervals. When driving, the positioning data stored in the information recording card 30 is read out to guide the vehicle's driving route, which eliminates the need to manually enter specific road data while looking at an atlas. Since it does not display the map directly and display the current position in combination with it, the means for displaying the map can be omitted, and it is an inexpensive device that can provide the driver with the necessary traveling direction and distance information. be able to.

In addition, since the automobile route guide device of this embodiment automatically generates road data manually when driving toward a specific destination, it saves the labor of human labor. By operating the registration switch 20, it is possible to register positioning data according to the road condition. For example, in a place with many intersections, positioning data can be registered even within a predetermined time interval set in the timer built into the calculation means 3. can be stored in the storage means 6, that is, in the information recording card 30, and can be recalled sequentially during the next road trip, thereby making it possible to inform the driver of detailed guidance information.

In particular, since the positioning data of the current position of the vehicle is stored at predetermined time intervals set in the timer,
When driving in urban areas where the vehicle speed is slow, a large amount of positioning data can be obtained, making it possible to provide guidance that matches the driver's sense of driving.

In this embodiment, the calculation means 3 stores the positioning data of the current position of the vehicle at predetermined time intervals set in a built-in timer, and inputs the driving information of the vehicle from the outside. Therefore, it does not require the output of sensors installed in automobiles, and can be installed regardless of the type of automobile, allowing standardization of the device. In addition, in this embodiment, the timing at which positioning data is stored by the timer can be changed by selecting the timing changeover switch 15, and the timing at which the positioning data is stored by the timer can be set at an interval with the traveling time, and the timing at which the positioning data is stored by the timer can be set in accordance with the travel time. The timing for obtaining positioning data can be determined according to the road conditions.

Furthermore, by operating the current position registration switch 20, the storage means 6 stores positioning data with the current position of the vehicle as the positioning point.
As a result, since the information is stored in the information recording card 3o, the positioning data with the own vehicle position at that time as the positioning point can be stored in the information recording card 3o regardless of the predetermined distance interval or time interval. This allows the driver to specify a necessary location based on his or her judgment, and allows the driver to store positioning data at the necessary location in the storage means 6 while checking the road condition.

Therefore, since they do not display road conditions mechanically, positioning data is input at intersections where people can easily make mistakes.
It can be used as a road guide.

Furthermore, when the storage capacity of the predetermined memory area of the information recording card 30 is filled, since the geography of places near the final destination is often unknown, the positioning data on the starting point side is thinned out, and the data at the final destination is By storing positioning data on the side, even if the storage capacity is exceeded, the density of the positioning data closer to the final destination can be increased to provide detailed information to the user.

In addition, since comments on positioning data are displayed on the display means 4, management of multiple routes, names of intersections, etc.
Road names etc. can be recorded, making it more practical.

Furthermore, since the predetermined driving route can be managed in units of information recording cards 30, management by destination becomes easy.
