It consists of a display section for displaying information. Some vehicles are equipped with a sound generator that outputs driving guidance information as sound. The travel guidance device is mounted on a vehicle and used, and when the driver inputs a departure point, destination point, waypoint, etc., the control device controls the travel guidance based on map data and output data of the sensor. The system creates guidance information and notifies the driver by displaying the created driving guidance information on the display section or by outputting it as a voice on the audio output. Therefore, the driver can reach the destination point by driving according to the travel guidance information received from the travel guidance device.

``Problems to be Solved by the Invention'' By the way, in the conventional travel guidance system, the initial operation had to be performed manually, which was inconvenient, especially when there was a situation where a departure had to be made in a hurry.

On the other hand, it is a rule of thumb that impressions of route points vary from person to person.

For this reason, with conventional travel guidance devices that create travel guidance information based only on ready-made map information, there is a risk that some drivers will be guided to the wrong destination point.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a travel guidance device whose initial operation is simple. Another object of the present invention is to provide a driving guidance device in which the driver himself/herself can input personal impression point data.

"Means for Solving the Problems -" In order to solve the above problems, the present invention provides a voice recognition unit that recognizes external input data, a personal information memory that stores the external input data, and a road map data storage unit. a map memory for detecting a vehicle, a position/traveling distance detection unit for detecting the position/traveling distance of a vehicle, and road map data in the road map memory;
Based on the external input data of the personal information memory and each output data from the voice recognition section and the position/traveling distance detection section, an information creation section that creates travel guidance information and a 111 information creation section. The vehicle is characterized by comprising a sound generating section that outputs the traveling guidance information as sound.

"Operation" According to the above configuration, it is possible to input by voice,
Initial operation becomes jR speed easier. Furthermore, since personal impression point data can be input and output, guidance tailored to the driver's personality is possible.

This makes it possible to guide the vehicle even more safely and reliably.

This is to notify the driver. Next, the operation of this embodiment will be explained.

FIG. 2 is a map showing the driving route in this example.

In this figure, it is assumed that the traveling guidance device of this example is applied when a certain vehicle travels from S as a starting point to a destination point G. Note that points A, B, and C on the map are intermediate points (impression points).

When the driver of the vehicle departs from point S, he turns on the power to the travel guidance device. When power is supplied to the travel guidance device, the CPU la prompts the driver to input cut-off data by voice according to the input processing procedure shown in FIG. First, in the Stenobu SA+, the CPUla sends a starting point input instruction signal to the audio synthesizer l3.

When the speech synthesizer 13 receives the starting point input instruction signal, it converts it into an audio signal and sends it to the speaker l4. In this way, the speaker 14 outputs a voice saying "Please input the starting point", and the sound is transmitted to the driver using sound waves as a medium. When the driver receives the voice instruction to input the starting point, he utters "S" (for the starting point) into the microphone 10 (step SA2). The microphone 10 sends the voice signal “S′” to the voice recognition device 1l. The voice recognition device 11 decodes the voice signal “S” and causes the CPUla to take in the decoding result. Next, the CPUla
The process proceeds to step SA3, and sends a destination point input instruction signal to the speech synthesizer l3. When the audio synthesis device l3 receives the destination point input instruction signal, it converts it into an audio signal and sends it to the speaker l4. Thus, subika l
4, a voice message saying "Please input the destination point" is output and transmitted to the driver. Upon receiving this voice instruction, the driver speaks into the microphone 10 (where is the destination)?
Say “G’” (Stenob SA4).Microphone 10
sends the voice signal "G" to the voice recognition device l1. The speech recognition device 11 decodes the speech signal "G" and causes the CPUla to take in the decoding result. Next, the CPUla proceeds to step SA5 and passes through the speech synthesizer l3 (impression).
Sends a point input instruction signal. When the voice synthesizer l3 receives the route (impression) point input instruction signal, it converts it into an audio signal and sends it to the speaker 14. Thus,
The speaker 14 outputs a voice saying "Please input the route point" and transmits it to the driver. When the driver receives this voice instruction, the driver sequentially speaks "A", "B", and "C" into the microphone 10 (for the route point).
A6).

The microphone 10 sequentially sends audio signals "A" and "B゛C" to the voice recognition device 11. voice recognition device
decodes the audio signals "A", "B", and "C" and causes the CPUla to take in the decoding results.

This completes the input processing procedure and then
starts the travel guidance instruction operation according to the processing procedure shown in FIG.

(1) When the vehicle travels between the starting point S and the first way point A, the CPUla first performs the following operations at an appropriate timing for travel guidance.
Sampling each output data of the direction sensor 2 and mileage sensor 3 (Steps SBl, SB2), calculate the current position and mileage (travel) distance based on each obtained sample value. Step SB3), and calculate the calculation results. R.A.
Store in MIC (Stesop S B4). The subsequent processing will be explained below by case.

(la) When there is no voice input of personal impression point information In this case, steps SB5 and SB6 are not processed,
The CPUla returns to step SB7 and creates travel guidance information based on the current position/travel data and map data, and provides the created travel guidance information to the driver by voice. For example, in step SB7, CPUla decides whether to go straight through the first T-junction (at waypoint A) or not.
Decide whether to turn right or left, and as a result of the decision,
Turn left at the first T-junction. ” (Figure 5). When the vehicle reaches the first T-junction, the driver follows the audio guidance
Turn left at the second T-junction.

(1b) When there is voice input of personal impression point information In this case, proceed to steps SB5 and SB (3 (Figure 4)),
Input, recognition, and recording processing of personal impression point data is executed. For example, when approaching the first waypoint A, the driver gets the impression that there is a ×× bank on the left corner.
``There is a bank. The decoding result is taken into the CPUla.When the CPUla takes in the decoding result at the step SB5, the CPUla stores the decoding result in the memory card l2 at the next step SB6.

(lc) When personal impression point information is recorded The driver has traveled this route before, and at that time, the process of (1b) above is performed and stored in the memory card 12 as personal impression point information. If the above (la
), when CPUla instructs travel guidance information, the personal information input in (lb) above, that is, "XX bank is on the left corner" is also reported. Thereby, the driver can obtain driving guidance that is easy for him/herself to understand.

(2) When the vehicle travels between the first waypoint 8 and the second waypoint B (2a) When the vehicle turns left at the first waypoint A, the CPU
After going through the same process as explained in (1) above, la gives a voice instruction, ``Please turn right at the second crossroads.'' (FIG. 5). Following this instruction, the driver goes straight at the first crossroads, and turns right when he reaches the second crossroads (ie, way point B) (FIG. 2).

(2b) When the vehicle approaches the second waypoint B, when the driver recognizes from road signs that the name of the crossroads is ○○ intersection, the microphone 1
0, input "Turn right at ○○ intersection" by voice.

When "Turn right at ○○ intersection" is input by voice, the same process as described above is performed, and the CPU l a stores the decoding result in the memory card l2 (steps SB5 and SB
6).

(2c) If the analysis result is stored in the memory card l2 (same case as in (la)), the CPU l2
When giving the above driving guidance instruction by voice, "O○
"Turn right at the intersection."

(3) Vehicle's second waypoint B and third waypoint C
(3a) When the vehicle turns right at the second waypoint B, the CP
After going through the same process as described in (1) above, Ula gives a voice instruction, "Please turn left at the first Y-junction." Following this instruction, when the vehicle reaches the Y-junction (ie, via point C), the driver turns left (FIG. 2).

(3b) In this case, when the vehicle approaches the third way point C, the facility of gas station △△ comes into view of the driver, and it is determined that this gas station △△ can be a feature point, The driver inputs voice into the microphone 10, ``There is a gas station △△ in front''. When there is a voice input saying “There is a gas station △△ in front”, the same process as described above is performed, and the CPU
la stores the decoding result in memory card l2 (
Steps SB5, SB6).

(3c) Furthermore, if the process in section 2 (3b) has been previously performed and the analysis result is stored in the memory cart river 2, the CPUla issues the travel guidance instruction (step SB
When performing step 7), an instruction such as "Gas station △△ available" is also given by voice.

Thus, by driving according to the instructions of the travel guidance device, the destination point G can be reached safely, reliably, and easily.

In addition, in the above-mentioned embodiment, a case was described in which a memory card was used as a means of storing personal information.
The present invention is not limited to this, and for example, a table recorder may be used.

In addition, in the above-mentioned embodiment, a case has been described in which information such as whether to turn right or left or the name of a building or facility is recorded as personal impression point information, but the information is not limited to this.
It may also be possible to store information such as the distance to a certain point, road width, and whether it is up or down.
