Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a navigation device for providing a driver with necessary information on a vehicle.

[0002]

2. Description of the Related Art Conventionally, various navigation devices have been developed which automatically measure the current position and perform distance, direction, route guidance, etc. to a destination or waypoint. In JP-A-58-26214, JP-A-59-2200, JP-A-60-218022, etc., a planned running course is set in advance, and when a preset point is reached during running, a voice message is output. A technique of reading voice data from a memory and outputting the voice from a speaker is disclosed. Further, there is a system in which the contents of the voice memory can be rewritten into voice data read from a microphone to use one's own voice.
No. 0-40909.

[0003]

In the conventional device, the voice data is read from the voice memory and output as voice at a preset route point on the preset running course.

Therefore, during traveling, voice data is not output until the set waypoint is reached. When turning right or left at an intersection, the output location of audio data varies depending on the size of the intersection and the detection accuracy of the current position. For example, in the case of a right or left turn on a narrow road with a speed limit of 40 km / h, even if voice data is output just before the intersection, the user can immediately respond to the voice data, but there are 3 or more lanes on one side, If you have a right-turn lane or a left-turn lane and you can drive at high speeds, you may miss the right or left turn at the intersection if you do not output audio at a point just before the intersection. Therefore, it is desired that the user can confirm the voice data to be output in advance by a key operation not only before the preset intersection but also while traveling to the intersection.

In view of the above points, an object of the present invention is to make it possible to confirm preset voice data which is voice-outputted at a preset point during traveling, at an arbitrary point.

[0006]

Means for Solving the Problems The means used in the present invention for solving the above problems are a destination / route memory for storing the positions of a plurality of destinations / routes, and a destination / route memory of destinations / routes. A selection means for selecting any one, a voice data memory capable of storing voice data as many as the number of destinations / routes, and a voice recording / playback means for exchanging voice data between a microphone, a speaker and a voice data memory. , Voice memo key, and voice data input means for controlling the voice recording / playback means so as to record the voice from the microphone according to the operation of the voice memo key in the voice data memory in association with the selected destination / route point. , Voice key, and voice recording to read the voice data of the destination / route selected from the voice data memory according to the operation of the voice key and send it to the speaker. A voice data output means for controlling the live means, a current position measuring means, and a destination of the position in the voice data memory when the measured current position is close to any one of a plurality of destinations / routes. -Voice guidance means for controlling the voice recording / playback means so as to read out the voice data from the location corresponding to the waypoint and send it to the speaker.

[0007]

According to the above means, when one of the plurality of destinations / routes set by the selecting means is selected and the voice memo key is operated, the user operates the voice data inputting means from the microphone to the voice data memory. The voice data generated by can be recorded using a voice recording / playback means. When the voice key is operated, the recorded voice data can be reproduced from the speaker using the voice recording / reproducing means by the action of the voice data output means. The recorded voice data is reproduced from the speaker when approaching the corresponding destination or waypoint. Therefore, if the user sets the positions of the destinations and transit points in advance and records the audio data corresponding to the destinations and transit points, the user will be guided by voice when approaching the destinations and transit points. Since it is possible to function as a navigation device, the user can travel along a preset route according to voice guidance. Furthermore, since the recorded content can be confirmed by pressing the voice key even before the point where the voice is guided, even if the voice is suddenly guided when approaching the destination or the waypoint, there is no need to worry.

As shown in the figure, the main road, the destination, and the direction thereof received from the transmitter arranged on the road are displayed, and road regulation information in the vicinity thereof is displayed. (G) is an example of the present location display. The map book number, the page number, the frame number, and the position in the frame are indicated by numbers, and the traveling locus and the current position in the frame are displayed. (H) is a display example of the setting screen. You can enter the destination / route number, map book number, page number, frame number, and position within the frame.

In the above embodiment, when approaching a preset destination or waypoint, prerecorded voice data is output. Still, the voice data can be confirmed in advance by pushing the voice key at any point desired by the user. For example, at each point on the map as shown in FIG. 20, route points 1 to 6 are set, voice recording is made at the route point 1 saying “Turn right at XX intersection”, and at the route point 2, “XX intersection” is set. Make a voice recording at each point of the destination or waypoint, such as "Left turn". After that, when departing from the start point, when the vehicle comes before the intersection designated by waypoint 1, the speaker automatically reproduces the voice "turn right at XX intersection". The same applies to other transit points. The user can reach the destination by driving according to the voice instruction. Here, the audio reproduction is interrupted until the right before the XX intersection is reached after turning right at the XX intersection of the waypoint 1. If the distance between the XX intersection and the XX intersection is long, the driver becomes worried. However, in this case, when the voice key is pressed, the voice data "XX intersection turn left" reproduced at the next intersection can be heard. Therefore, if the driver puts in his head that he will make a left turn at the XX intersection, he / she can immediately respond when the XX intersection is actually reached and voice data is automatically generated. By pressing the voice key, the driver can confirm the voice data to be guided next time in advance, so if you are turning left you should be close to the driving lane, if you are turning right you should be in the overtaking lane. You can be ready before being voice-guided, such as leaning towards or slowing down.

Although the recording time of the voice data is set to 4 seconds in the above embodiment, this time can be changed as required.

[0059]
