Abstract

PURPOSE: To set a destination safely and easily even while a vehicle is running by recognizing a word generated correspondingly to the destination among registered points. CONSTITUTION: A driver preliminarily registers a destination for a vehicle to a point-registering means 103, and sets a name of the registered point by a name-setting means 104. When the name is not set, a word and the point are arranged to correspond each other at an initialization step. In setting a course, when the name of the destination or the initially set word is uttered, a voice-recognizing means 105 recognizes the name or word and a course-setting means 102 sets a course including the point corresponding to the recognized word as the destination under the control of a control means 106. For example, an address of the driver's home is registered at 103 and a name 'home' is set at 104. After the setting, when the driver sounds 'home', a course wherein a corresponding point to the sounded 'home' is a destination is set at 102. In this manner, a complicate setting operation of steps is totally elimnated. Moreover, the driver needs not to look at a screen to set the destination and therefore the driver can concentrate his or her attention on driving, thereby improving safety.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle-mounted navigation device for inputting a destination of a vehicle by voice and setting a traveling route to the destination.

[0002]

2. Description of the Related Art In a vehicle-mounted navigation device, when a travel route to a destination is searched, it is necessary to set a destination point in advance. In the conventional navigation device, a method of setting by a prefecture name or a municipality name, a method of moving a cursor and selecting from a pre-registered point, and the like are used.

[0003]

However, the destination setting operation in the conventional vehicle-mounted navigation device has a complicated hierarchy, and many selection operations are required until the final destination is set. Also, since these are operations while checking the screen, it is extremely dangerous while driving, and setting operations during running are often prohibited,
There was a problem that the destination setting operation could not be performed while driving.

The present invention solves the above-mentioned problems of the prior art. It is possible to set the destination safely and easily even while the vehicle is running, and the voice operation without any setting operation while checking the screen is performed. It is an object of the present invention to provide a vehicle-mounted navigation device capable of setting a destination according to.

[0005]

In order to achieve the above object, the present invention provides a vehicle current position estimating means for estimating the current position of a vehicle, a route setting means for setting a traveling route to a destination of the vehicle, and a map. It is equipped with a point registration means capable of registering a plurality of arbitrary points above and a voice recognition means for recognizing a plurality of vocabulary of unspecified speaker voices, and the driver selects a destination from the points registered in the point registration means. By uttering the vocabulary corresponding to the point, the voice recognition means recognizes the vocabulary, and the travel route is set with the point corresponding to the recognized vocabulary as the destination of the vehicle.

Further, according to the present invention, the voice recognition means is provided by separately providing a name setting means for setting a name at each point registered by the point registration means, and the driver uttering the name of the destination point. Recognizes this and sets the traveling route with the point corresponding to the recognized name as the destination.

[0007]

Therefore, according to the present invention, when the driver sets the traveling route to the destination, the destination is set by uttering the vocabulary corresponding to the destination point from the registered points. Since it is possible to end the process and start setting the travel route, it is possible to omit any complicated setting operation while checking the conventional screen.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows the configuration of an embodiment of the present invention. Reference numeral 101 is a vehicle current position estimating means for estimating the current position of the vehicle, 102 is a route setting means for setting a traveling route from the current position to a destination, 103 is a point registration means capable of registering a plurality of arbitrary points on the map, and 104 is registration. Designated name setting means for setting a name at each of the designated points, and 105 is a voice recognition means for recognizing a plurality of vocabularies of an unspecified speaker. 10
Reference numeral 6 denotes a control unit, which controls the entire device such as the route setting unit 102, the point registration unit 103, and the name setting unit 104 based on the outputs of the vehicle current position estimation unit 101, the voice recognition unit 105, and the like.

Next, the operation of the above embodiment will be described. The driver registers the destination point of the vehicle in the point registration means 103 in advance, and sets the registered name of the registered point by the name setting means 104. If the name is not set, the vocabulary and point by default are associated.
When the driver sets the route, by uttering the name of the destination or the vocabulary set by the initial setting,
The voice recognition means 105 recognizes the route, and the route corresponding to the recognized vocabulary is set as the destination. For example, the address of the driver's home is registered by the point registration means 103, and the name "home" is set by the name setting means 104. If no name is set, a vocabulary such as "Point A" is set as the initial setting. In addition, points such as “company” that are frequently used as destinations by drivers are similarly set. After these setting operations, when the driver utters a vocabulary such as "home", the route is set with the point corresponding to "home" as the destination.

As described above, according to the above embodiment, if the destination point is registered in advance and the name of the registered point is set, the name of the set point or the vocabulary by the initial setting is uttered. As a result, a route can be set with this point as the destination. Therefore, as in the past, you can select and set the name of the prefecture or the name of the municipality,
Further, it is not necessary to move the cursor to select from the registered points, and the destination can be set by a method like a speed dial of a telephone.

[0011]

As is apparent from the above embodiment, the present invention corresponds to a desired destination among registered points when the driver wants to set a traveling route to the destination. Since it is possible to set the destination and start setting the travel route simply by uttering the vocabulary, it is possible to omit the conventional setting operation according to the complicated hierarchy. Further, since it is not necessary to look at the screen for setting, the driver can concentrate on driving, which has an effect of improving safety. As a result, it becomes possible to safely perform destination setting and setting while traveling, which is conventionally prohibited.

Since the voice recognition means recognizes the voice of an unspecified speaker, the driver does not need to register his / her voice in advance, and the burden of operation at the start of use can be greatly reduced.
