Here, FIG. 1 is a configuration diagram of a navigation device using ATIS communication according to claim 1, FIG. 2 is a configuration diagram of a navigation device using ATIS communication according to claim 2, and FIG. 3 is a flowchart of a navigation device using ATIS communication.

The navigation device based on ATIS communication according to the first aspect is a system for communication from a vehicle. As shown in FIG. 1, a navigation device body 1, an operation device 2 including a keyboard, a mobile phone 3, an ATI.
It comprises an S communication unit 4, a display 5, a map information storage medium 6 such as a CD-ROM map storing ATIS link information, and a speaker 7. Further, the operating device 2 is provided with a communication interval setting means 8 for arbitrarily setting a communication interval. The navigation device main body 1 includes a control unit 10 and a timer 17 for managing a communication interval.

Further, the navigation device based on ATIS communication according to claim 2 is a system for communicating from inside a room such as an office, and as shown in FIG.
In contrast to the navigation device using the ATIS communication according to
In addition to the above, the vehicle further includes a vehicle position detection unit 11, a vehicle speed sensor 12, a direction sensor 13 such as a gyro, a GPS antenna 14, and a route guidance unit 15.

The operation of the navigation device based on the ATIS communication configured as described above will be described with reference to the flowchart shown in FIG. Although the flowchart shown in FIG. 3 mainly describes the operation of the navigation device based on the ATIS communication according to the second aspect, the navigation device based on the ATIS communication according to the first aspect has common steps. I will explain.

First, in the case of the navigation device based on ATIS communication according to the first aspect, the CD-RO is operated by a mouse or the like.
The user inputs two points by, for example, clicking on the map obtained from M (step S1). ATIS according to claim 2
In the case of a navigation device by communication, the current position is detected by the vehicle position detection unit 11 based on output signals from the vehicle speed sensor 12, the direction sensor 13, and the GPS antenna 14, and the current position is input to the control unit 10 ( Step S
1).

Next, in the case of the navigation device by ATIS communication according to the first aspect, the communication interval setting means 8
To set the communication interval in the timer 17 (step S
2). In the case of the navigation device by ATIS communication according to the second aspect, the destination is set by the keyboard of the operation device 2, the destination is input to the control unit 10, and the communication interval is set by the communication interval setting means 8 as a timer. 17 (step S2). Here, the communication interval means that the current position and the destination are determined by the ATIS communication from the navigation device in order to receive the latest optimal route information service between the current position and the destination.
Center).

Next, two points, that is, the current position and the destination, or any two points are transmitted from the control unit 10 to the traffic information center via the ATIS communication unit 4 and the portable telephone 3 through a telephone line. Then, the traffic information center searches for the optimal route information in consideration of the road conditions between the transmitted current position and the two points of the destination or between any two points, and transmits the optimal route information between the two points via the telephone line. Then, an input is made to the control unit 10 (step S3).

Next, the optimal route information transmitted from the traffic information center is displayed on the map stored in the CD-ROM by the display 5, and the route guidance of the vehicle is performed together with the voice information from the speaker 7 (step S4). .

Further, in step S5, the elapsed time with respect to the communication interval time set in the timer 17 from the time when the current position and the destination or any two points are transmitted to the traffic information center is counted. It is determined whether or not the time (communication interval time) has elapsed. If it is determined that the set time has not elapsed, step S6
Proceed to.

On the other hand, if it is determined that the set time has elapsed, the control unit 10 drives the ATIS communication unit 4 to again connect the current position and the destination or any two points to the traffic information center through the telephone line. The CD-RO transmits the latest optimal route information between the two points transmitted from the traffic information center.
The information is displayed on the map stored in M by the display 5, and the route guidance of the vehicle is performed together with the voice information from the speaker 7 (step S7).

In step S7, the current position transmitted to the traffic information center again may be the current position transmitted in step S1, the vehicle speed sensor 12, the direction sensor 1
3 and the current position obtained by the vehicle position detection unit 11 based on output signals from the GPS antenna 14. However,
The current position obtained by the vehicle position detection unit 11 is more preferable. At the entrance of an expressway, the traveling direction of the vehicle may be required.
The traveling direction is also transmitted based on the traveling direction obtained in (1).

In step S6, the control unit 10 determines whether or not the vehicle has deviated from the optimal route transmitted from the traffic information center based on the output signals of the vehicle position detecting unit 11 and the route guidance unit 15, and determines from the optimal route. If it is determined that the route is deviated, the process proceeds to step S7. If it is determined that the route is not deviated from the optimal route, the process proceeds to step S8. When the vehicle deviates from the optimum route, the current position transmitted to the traffic information center again in step S7 is the vehicle speed sensor 12, the direction sensor 13
And the current position obtained by the vehicle position detection unit 11 based on the output signal from the GPS antenna 14.

In step S8, it is determined whether or not the vehicle has arrived at the destination. If it has not arrived, the process returns to step S5, and if it has arrived, the route guidance ends.

If the latest optimum route is different from the previous route in step S7, the driver or the like is alerted by voice information from the speaker 7 and the change status is highlighted on the display 5. Route guidance with certainty. Further, if there is a problem with the communication at present for the user's convenience or if the user intentionally deviates from the route, the communication is accepted by the user before communication in step S7. It may be set to do so.

When ATI communication is performed in a room such as an office, as shown in FIG. 1, the system configuration except for the calculation of the vehicle position and the route guidance is performed.
The S communication is performed, and the latest optimal route between the two set points is displayed on the display 5.
