Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a navigation device mounted on a vehicle and capable of communicating with the outside via a detachably connected portable terminal. The present invention relates to a technology for performing an automatic response.

[0002]

2. Description of the Related Art Conventionally, for example, Japanese Patent Application Laid-Open No. H11-132778.
For example, when a mobile terminal such as a mobile phone that can be connected to a navigation terminal receives an incoming call while the vehicle is running, as in the route guidance device disclosed in 2. Description of the Related Art There is known a navigation apparatus that automatically transmits an audio signal including information such as a current position and a traveling direction of a vehicle together with a set predetermined response message. In such a navigation device,
Upon receiving the voice signal of the automatic response from the navigation device, the communication partner for the incoming call of the mobile terminal must understand that the owner of the mobile terminal is driving the vehicle and cannot respond to the incoming call. Have been able to.

[0003]

By the way, in the route guidance apparatus according to the above-mentioned prior art, information such as the current position and the traveling direction of the vehicle is displayed together with a response message notifying that the owner of the portable terminal cannot respond to the incoming call. Since the caller is automatically notified as a voice signal, information such as the current position and the traveling direction of the vehicle is notified even for an incoming call from an unspecified number of people. For this reason, the owner of the mobile terminal cannot perform detailed operation settings for the automatic response, for example, the setting of a partner who is notified of vehicle information, and cannot protect the privacy of the owner of the mobile terminal. There is. The present invention has been made in view of the above circumstances, and provides a navigation device capable of performing flexible operation setting according to an operator's request for an automatic response and protecting the privacy of the operator. The purpose is to provide.

[0004]

In order to solve the above-mentioned problems and achieve the object, a navigation device according to the present invention is provided with a unique identification number (for example, a telephone in an embodiment described later). (For example, a communication terminal 11 in an embodiment to be described later)
And position detection means for detecting the current position of the vehicle (for example,
The vehicle position detecting unit 31 in an embodiment described later), a destination input unit (for example, the input unit 12 in an embodiment described later) for inputting a waypoint or a destination, and map data storage for storing map data Means (for example, a map data storage unit 15 in an embodiment to be described later) and a route calculating means for calculating a travel route from the map data based on the current position of the vehicle and the destination (for example, an embodiment to be described later) And a route information storage unit (for example, a destination setting unit 35 in an embodiment to be described later) that stores the identification numbers that are different for each of the destinations or the waypoints on the travel route. ), When there is an incoming call to the communication means from an external communication partner, the identification number of the communication partner and the destination or the transit point stored in the route information storage means. Identification number comparing means for comparing the identification number (e.g., telephone number comparing section 3 in the embodiments described below
3) and when the identification number comparing means determines that the identification number of the communication partner and the identification number of the destination or the stopover point coincide with each other, the information relating to the current position of the vehicle is converted into the information. A vehicle information notifying means (for example, a hands-free device 34 in an embodiment described later) for automatically transmitting to a communication partner is provided.

According to the navigation device having the above configuration,
In advance, the operator stores a predetermined identification number such as a telephone number in association with the destination or the waypoint on the travel route. When an incoming call is received by a communication means such as a mobile phone owned by the operator, the telephone number of the communication partner of the incoming call is compared with a telephone number stored in advance. As a result of this comparison, if it is determined that they match, for example, the operator is driving the vehicle and together with a message notifying that it cannot respond to an incoming call,
A voice message for notifying information about the current position of the vehicle, for example, information such as the current position of the vehicle, the distance to the destination or the waypoint, and the estimated time of arrival at the destination or the waypoint is transmitted to the communication partner. On the other hand, if it is determined as a comparison result that they do not match, for example, the operator transmits only a message notifying that the vehicle is driving and cannot respond to an incoming call to the communication partner. As a result, as a communication partner set in advance by the operator, it is possible to notify the information regarding the current position of the vehicle only to the destination or the waypoint on the travel route, for example, from other places deviating from the travel route of the vehicle. In response to an incoming call, it is possible to protect the privacy of the operator and perform an appropriate automatic response without notifying information on the current position of the vehicle.

Further, according to a second aspect of the present invention, there is provided the navigation device, wherein the destination or the stopover and the current position of the vehicle are determined based on the destination or the stopover and the current position of the vehicle. Distance calculating means (for example, the route calculating unit 32 also serves as an embodiment to be described later) for calculating a distance between the vehicle and the vehicle information notifying means. It is characterized by being transmitted to.

According to the navigation device having the above configuration,
When there is an incoming call from a destination or a waypoint, a voice message notifying of the current position of the vehicle is transmitted, and the distance between the communication partner and the current position of the vehicle is calculated. Send a voice message notifying you of distance information. Thereby, the communication partner existing on the traveling route of the vehicle can easily acquire the information on the current position of the operator and the distance to the current position. In this case, together with the distance information, for example, information such as the estimated arrival time of the vehicle may be transmitted to the communication partner, so that the communication partner can make appropriate preparations in anticipation of the arrival of the vehicle.

Further, in the navigation apparatus according to the third aspect of the present invention, position information storage means for storing position information on the current position of the vehicle (for example, in an embodiment to be described later, the map data storage unit 15 also serves). Wherein the vehicle information notifying means extracts the position information on the current position of the vehicle from the position information storage means and automatically transmits the position information to the communication partner.

According to the navigation device having the above configuration,
When there is an incoming call from a destination or a waypoint, a voice message notifying the current position of the vehicle is transmitted, and a voice message notifying the position information of the current position of the vehicle is transmitted to the communication partner. Thus, the communication partner can easily acquire the current position of the operator and the position information of the current position. In this case, together with the position information, for example, information such as the estimated arrival time of the vehicle may be transmitted to the communication partner, so that the communication partner can make appropriate preparations and the like in anticipation of the arrival of the vehicle.
