Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a voice guidance type road guidance device for a vehicle.

[Conventional technology]

BACKGROUND ART Recently, the number of automobiles has increased rapidly, and arterial roads, especially in large cities and surrounding cities, are becoming congested every day. For this reason, many drivers try to avoid these congested roads and take so-called back roads to reach their destinations. For this reason, bookstores are selling atlases with detailed information on back roads for driving on these back roads.

Conventionally, when driving on an unfamiliar road, such as when passing through a back road as mentioned above, an atlas or the like has been used as a means of road guidance, and the driver drives a car while looking at this atlas, etc. This allows you to reach your destination. On the other hand, the National Highway Corporation, the police, automobile manufacturers, etc. have come together to form a project to provide drivers of each vehicle with information on road congestion and directions to get to their destination in the shortest possible time in order to alleviate traffic congestion. A navigation system is also under development.

[Problem to be solved by the invention]

However, when an atlas is used as a road guide as described above, it becomes extremely difficult to drive as it distracts attention. In particular, back roads like those marked on the map are usually narrow and crowded with people. There was a problem that there was an added danger when driving a vehicle. Furthermore, the navigation system described above has not yet become widespread at this stage, and even if it were to become widespread, it would require fairly expensive equipment, making it difficult for general users to use it right away. There is a point.

The present invention has been made in view of these problems, and an object of the present invention is to provide a road guide device for a vehicle that is safe, inexpensive, and does not interfere with driving.

[Means to solve the problem]

The road guidance device for a vehicle of the present invention includes an audio recording medium that records road guidance information step by step in accordance with the progress of the vehicle, and a regenerator that plays back the recorded information at each step according to switch operation. In addition, the above-mentioned reproducing device is configured to repeatedly reproduce recorded information by operating a switch.

[Effect]

In the road guidance device for a vehicle of the present invention, road guidance information can be opened by voice, and can be obtained step by step according to the progress of the vehicle by a simple switch operation.

〔Example〕

FIG. 1 is a block diagram showing the basic configuration of a road guide device for a vehicle according to the present invention. That is, this device includes an audio recording medium 1 that records road guidance information step by step in accordance with the progress of the vehicle, and a dedicated player 3 that plays back the recorded information step by step according to the operation of a switch 2. The reproducing device 3 can repeatedly reproduce recorded information by operating the switch 2.

The audio recording medium 1 may be a cassette tape or a CD (
A compact disc), a voice synthesis ROM, a card, etc. can be used, and as the player 3, a tape recorder, a CD player, etc. can be used, and the road guide information is announced from a speaker.

FIG. 2 is an external view showing a specific example of the guide device having the above configuration. In this example, a cassette tape, a CD, and a card can be used as the audio recording medium 1, and each tape recorder is used as the player 3.

It has a built-in playback means such as a CD player.

In the figure, 4 is a power switch, 11, 12, and 13 are slots for the cassette tape, CD, and card, 21 is a numeric keypad switch, and 22, 23, and 24 are reset (RE)
SET) switch, search (5EARCH)
25 is a step down (STEP DOWN) switch, 26 is a step up (STEP UP) switch, and 27 is a replay (REPLAY) switch for repeated playback. Switches 21 to 27 constitute switch 2 in FIG. 31 and 32 are a counter display section and a speaker of the regenerator 3, respectively.

In the road guidance device configured in this way, for example, a back road route (point landmarks and courses) is recorded step by step (step by step) on an audio recording medium 1 such as a cassette tape or CD in advance. In addition to recording the information, the driver should check in advance only the points where he or she enters the back roads (an atlas is required only when entering the back roads).

After entering the back road, the driver sets the recording medium 1 through any of the mounting ports 11 to 13 and presses the start switch 24. As a result, information on the back road route and each target point is announced from the speaker 32 in order. At that time, the driver presses the step-up switch 26 each time the vehicle passes each point as the vehicle progresses, and the information for the next point is announced each time, allowing the driver to reliably drive on the back roads in accordance with the guidance information. be able to. Furthermore, if the user misses the announcement, the user can listen to the guidance information again by pressing the replay switch 27. Furthermore, if the guidance information goes too far ahead of the actual driving location, the step down switch 25
You can restore it with . In such a case, it is also possible to reset to the initial state using the reset switch 22, or to move to a point several steps earlier or later using the numeric keypad switch 21 and search switch 23.

In this way, the driver can reach the destination safely and quickly through the back roads, but in this case, the driver does not have to drive down the back roads while looking at an atlas as in the past, and the switch 2 is easy to use. You can get road guidance information with simple operations. Accordingly, it becomes easier to drive on unfamiliar roads such as back roads, the causes of traffic accidents such as distracted driving can be eliminated, and it is safe and can be done with an inexpensive device. Furthermore, if a route to avoid traffic congestion is included in the road guidance information, each driver can individually avoid the congestion area, and large-scale traffic congestion can be eliminated as a whole.

Next, the operation when actually driving on a back road will be explained.

For example, if you are driving on a road like the one shown in Figure 3,
If the main street in the direction is congested and the driver wishes to drive on a back road in the direction of arrow B, he or she presses the start switch 24 shown in FIG. 2 at a previously checked location. As a result, the speaker 32 plays a voice that says, for example, "I will now give you directions to National Route 246 towards Shibuya." followed by "Step No. 1. First, O〇3-chome gas station ( Please turn left at the corner of point P1).'' is heard. Then, when the driver reaches point PI, he presses the step-up switch 26. At this time, the speaker 32 also said, ``Step No. 2. Run straight until the second traffic light, and when you see the mailbox (point P2) on your left and the tobacco shop (point P3) on your right, turn right at the corner. Please.'' is heard. The driver drives the car further and presses the step-up switch 26 again, and a voice from the speaker 32 says, "Step No. 3. Pass the traffic light and turn left at the corner of the ramen shop (point P4)." flows.

In this way, the driver switches step-up switch 2
By simply operating 6, you can get road guidance information, and you can reliably travel on the back roads as shown by the arrows in the figure, passing through the tennis club (points ps) and superstore (points pi).

At that time, if the driver goes too far past the target point, he can listen to the announcement from the previous step by operating the step-down switch 25 as described above, and if the driver misses the announcement, he can press the replay switch. You can listen to the same announcement again by performing step 27. And finally, thank you from speaker 32 for your hard work. This concludes O○'s (back) directions. ” is heard and the navigation ends.

〔Effect of the invention〕

As described above, according to the present invention, road guidance information is recorded in audio and the recorded information can be listened to step by step by operating a switch, thereby eliminating causes such as distracted driving.
It has the effect of being able to know road guidance information without hindering driving, being safe and inexpensive.
