A navigation device adapted to display on a display device configured by an RT or the like is mounted on a vehicle and used. Such a navigation device generally includes a distance sensor and an azimuth sensor, and the output of each of these sensors is given to the position detector. The position detection unit detects the current position data of the vehicle based on the output of each sensor, and the detected current position data is given to the control unit (computer). The control unit reads out the map data of a certain range around the detected current position from the map memory composed of a CD-ROM or the like, and displays the current position on the display device together with the map around the current position.

By the way, the above navigation device includes
Usually, a function of setting a destination (including a transit point, the same applies hereinafter) is added. This destination is set, for example, by displaying a road map on the display device, operating the cursor movement key to move the cursor to a desired point (intersection, building, etc.), and pressing the execute key. Such settings are generally made by the driver before departure, and once the destination is set, the destination is displayed as a mark while driving, and the direction and straight line distance to the destination are displayed at the same time. To be done. Also, when the vehicle arrives at its destination, arrival guidance is given by voice or the like. Therefore, the driver can confirm whether the vehicle is heading correctly to the destination. Therefore, this function is mainly used when traveling or driving.

On the other hand, recently, when the delivery destination is set as the destination, the package can be reliably delivered to the delivery destination, so that the destination setting function is frequently used by the logistics companies. ing. However, the logistics company rarely delivers the package to one delivery destination, and normally delivers the package to a plurality of delivery destinations. That is, the driver has to set a plurality of delivery destinations as destinations by the complicated setting method as described above before departure, which increases the burden on the driver and reduces the efficiency of work. It was

Further, in the above-mentioned logistics company, when the delivery destination of the package has a plurality of deliverable points such as companies, the delivery destination may be changed after departure. That is, for example, after the departure is set after the destination is planned to be delivered to the point A before the departure, it may be changed to the point B due to the convenience of the delivery destination. In such a case, normally, the management section of the logistics company is first contacted by the delivery destination, and then the driver is informed that the delivery destination has been changed by, for example, a car telephone. Then, the driver purposely stops the vehicle (it is impossible to set the destination while the vehicle is traveling) and resets the destination to the change destination.

That is, in the above case, there is a problem that it is inefficient and inconvenient, and that it takes a certain amount of time to complete the changing operation, which may delay the delivery time. Therefore, an object of the present invention is to provide a destination setting system capable of remotely setting a destination in a vehicle-mounted navigation device from a control station.

The navigation unit 20 is also connected to a destination data storage device 26 including a flash memory for storing the destination data transmitted from the control station 2.

FIG. 2 is a diagram showing the structure of transmission data transmitted from the control station 2. The transmission data is transmitted in time series. First, the SOD 40 representing the beginning of the transmission data is transmitted. Next, the data type 41 for specifying in what format the destination data is transmitted is transmitted, and then the destination data 42 is transmitted. And finally, the EOD 43 indicating the end of the transmission data
Will be sent.

The destination data 42 is constructed in any form of coordinate data, place name data, and facility data, for example. Among them, for example, the coordinate data has a content of “map number, X coordinate, Y coordinate, additional data”. Here, the additional data (guidance data) is information about the destination, such as the telephone number or address of the destination, the name of the person who manages the building if the destination is a building, or Includes the names and landmarks of those who live in the building. The map number is a number given to a map obtained by vertically and horizontally cutting a map of Japan. On the other hand, in the case of the place name data or the facility data, the map number is not included, and the code corresponding to the place name or the facility name is used instead of the X and Y coordinates. The data type 41 is composed of, for example, 2 bits. For example, "01" represents coordinate data, "10" represents place name data, and "00" represents facility data.

The procedure of destination setting in the destination setting system will be described below with reference to FIG. When a destination is input from the input device 4 provided in the control station 2, the destination is converted into destination data (coordinate data, place name data or facility data), and then sent to the control device 5. It is temporarily held in the buffer 6. Next, the telephone number of the automobile telephone 22 provided in the vehicle is input from the input device 4. The input telephone number is sent to the control device 5, and when the control device 5 receives this telephone number, it sends a control signal indicating a call request to the modem 6. The modem 6 that receives this call makes a call, and the telephone station that receives this call selects a telephone station in the area where the vehicle is present, and then connects the line with the automobile telephone 22.

When the line with the automobile telephone 22 is connected, a response signal is sent from the telephone station in the area where the vehicle is present to the control station 2. When the control station 2 receives this response signal, the control device 5 Transmits a signal indicating the activation command to the navigation device 1. When the navigation device 1 receives the signal indicating this activation command and the navigation unit 20 is ready to receive data,
Acknowledge (ACK) indicating that data can be received
The signal is returned to the control station 2. This AC in the control station 2
When the K signal is received, the control device 5 reads the destination data temporarily stored in the buffer 6, converts the destination data into the transmission data described in FIG. 2, and then transmits the transmission data. When the navigation unit 20 finishes receiving the destination data, it transmits an ACK signal indicating the end of reception, and the control device 5 receiving this ACK signal disconnects the line.

The destination data is transmitted to the navigation device 1 as described above. The destination data is transmitted in any of the coordinate data, the place name data, and the facility data as described above. here,
When the coordinate data is transmitted, the navigation unit 20 can directly set the X-coordinate and Y-coordinate points forming the coordinate data as the destination.
On the other hand, in the case of place name data or facility data, it cannot be set as the destination as it is. Therefore, in this embodiment, the navigation unit 20 is provided with the map number data corresponding to the place name data or the facility data, X
A memory 50 (see FIG. 1) storing the coordinates and the Y coordinate is provided so that the navigation unit 20 recognizes the point corresponding to the transmitted place name data or facility data.

The operation of the navigation device 1 after the destination data is transmitted will be described below. When the destination data is transmitted from the control station 2, the destination data is sent to the destination data storage device 26 via the navigation unit 20 and stored therein. At the same time, the navigation unit 20 causes the display device 24 to display a message for notifying the driver that the destination data has been received by interruption. The driver who sees this message confirms the destination by input device 2
A predetermined confirmation operation is performed according to 5. Note that a speaker may be connected to the navigation unit 20 to notify by voice that the destination data has been received.

When the driver performs a predetermined confirmation operation, the navigation unit 20 reads the destination data from the destination data storage device 26 and the road map data including the destination from the map data storage device 23. The destination data and road map data thus read are sent to the display device 24 and displayed. By looking at this, the driver can confirm that the destination has been set.

In addition to this, when the driver operates the input device 25 by a predetermined method, if the additional data is added to the destination data, the additional data is displayed in the lower part of the map display screen including the destination. can do. A specific operation procedure for displaying the additional data will be described. First, the selection switch 60 shown in FIG. 3A is operated to move the cursor (crossed solid line) on the screen. Then, move the cursor to one of the destinations already displayed, for example, the destination number is "x".
When the input switch 61 is pressed in accordance with "1", additional data relating to the "x1", for example, "△△ Co., Ltd. 06- ×××-○○○○ Konohana-ku, Osaka City ...
Additional data such as "..." is displayed.

Further, in this map display screen, as shown in FIG.
As shown in, the “all destinations” key 62 is displayed, and next to it, the number of all destinations (8 points in the figure) is displayed. Here, when the cursor is moved to the "all destinations" key 62 and the input switch 61 is pressed, the display screen is switched to the additional data list screen as shown in FIG. 3 (b).
However, if the additional data of all the destinations cannot be displayed on one screen, the additional data is displayed on a plurality of screens. In this case, when the next item key 63 is pressed, it is possible to switch to the next screen. Also, by pressing the previous item key 64, it is possible to return to the previous screen. Of the destination numbers 65 displayed on the additional data list screen shown in FIG. 3B, move the cursor to the desired destination number 65 and press the input switch 61 to return to FIG. ) Is switched to the map display screen, and the additional data of the destination data corresponding to the destination number 65 is displayed in the lower part of the map display screen.

As described above, according to the destination setting system of this embodiment, the destination setting in the navigation device 1 can be performed by remote control from the control station 2.
The driver does not have to set the destination, which reduces the burden. In addition, since the destination setting becomes more flexible than in the conventional case, the navigation device 1 can be used more effectively.

In the above description, it is assumed that the vehicle has not set the destination before the departure. However, for example, after the destination is set before the departure and the vehicle is started, the destination is added or The present invention can be applied even if there is a change. For example, when the destination is added, when the additional destination data is transmitted from the control station 2, the destination data is stored in the destination data storage device 26 via the navigation unit 20. Thereby, additional destination data can be set. The driver can be informed that the destination data has been added by displaying a message indicating that the destination data has been added on the display device 24.

Further, when the destination is changed, the destination data of the changed destination is transmitted from the control station 2 and any of the destination data already set is sent along with this. Data indicating whether to change is transmitted. When these data are received by the navigation unit 20, the navigation unit 20 recognizes which destination data to be changed stored in the destination data storage device 26 is, and recognizes the recognized destination to be changed. Rewrite the destination data to the destination data you want to change.
Thereby, the destination can be changed. Also,
Similarly to the above, if a message for notifying the change of the destination is displayed on the display device 24, the driver can be notified that the destination has been changed.

Further, for example, in a logistics company,
A configuration may be adopted in which the host computer of the central headquarters is connected to the control device 5 via a communication network. In this way, since the destinations can be collectively set in the navigation device 1 at the central headquarters, it is possible to centrally manage the delivery destination of each vehicle at the central headquarters.

Although the embodiments have been described above, the present invention is not limited to the above embodiments. For example, in the above embodiment, the navigation device 1 and the control station 2
Although the wireless connection was made between and, it may be connected by wire, for example. According to this, the destination in the navigation device 1 can be set from the control station 2 when the vehicle is stopped near the control station 2.

In addition, various design changes can be made without changing the gist of the present invention.

[0033]

As described above, according to the destination setting system of the present invention, since the destination can be set in the vehicle-mounted navigation device by remote control from the control station, the burden on the driver can be reduced. Further, since the setting of the destination becomes more flexible than in the conventional case, the in-vehicle navigation device can be used more effectively, which is very convenient. Further, for example, a logistics company can eliminate delays in delivery time by eliminating wasted time to stop and change destinations after departure, thus improving service to delivery destinations. Can be planned.

In particular, according to the structure of claim 4, for example, a logistics company can set the destination in the vehicle-mounted navigation device by remote control from the central headquarters, so that each vehicle is delivered at the central headquarters. It enables centralized management.
