In the system described in Patent Document 1, when a target position is set in a car navigation device as an in-vehicle device in accordance with an instruction from the vehicle management center, after the setting, the calculation function provided in the car navigation device is used. The estimated arrival time to the location is calculated. Then, the calculated estimated arrival time is displayed on the display unit of the car navigation device.
Thus, when the target position is set by the car navigation device, displaying the estimated arrival time on the screen of the car navigation device has been conventionally performed. Even when the center and the system are combined, the estimated arrival time of the target position is only displayed on the screen of the car navigation device in the vehicle.

  Therefore, the vehicle management center has a problem that it is impossible to confirm the arrival time of each vehicle to the target position and the distance to the target position. In addition, the estimated arrival time calculated by an in-vehicle device such as a navigation device is often corrected during traveling due to actual road congestion, but the vehicle management center has corrected the estimated arrival time. Even so, there was a problem that I could not know that.

  The present invention has been made in view of these points, and when a target position is set in an in-vehicle device according to an instruction from the vehicle management center, information on arrival time and the like can be confirmed well on the center side. With the goal.

The present invention includes a vehicle information display device installed in a vehicle management center and an in-vehicle device mounted on a vehicle managed by the vehicle information display device, and communicates between the vehicle information display device and the in-vehicle device.

5. Modified example

[1. System configuration example]
A system configuration example according to an embodiment of the present invention will be described with reference to FIG.
The system of the example of the present embodiment includes a vehicle information display device 10 installed in a vehicle management center and an in-vehicle device 20 mounted on a vehicle managed by the vehicle management center. Although only one device is shown in FIG. 1, the in-vehicle device 10 is actually composed of a plurality of in-vehicle devices 20 mounted for each of a plurality of vehicles.

  The vehicle information display device 10 includes a communication processing unit 11, and the in-vehicle device 20 includes a communication processing unit 21, and performs communication between the vehicle information display device 10 and the in-vehicle device 20 as needed. In FIG. 1, an antenna 12 is connected to the communication processing unit 11 of the vehicle information display device 10, an antenna 22 is connected to the communication processing unit 21 of the in-vehicle device 20, and wireless communication is performed between the antennas 12 and 22. However, the communication processing unit 11 of the vehicle information display device 10 on the center side does not always perform direct wireless communication. For example, the center side may be configured to be connected to a wireless communication system that performs wireless communication with the in-vehicle device via some communication line or telephone line.

  The configuration of the vehicle information display device 10 installed in the vehicle management center will be described. The vehicle information display device 10 includes a target position input unit 14, and information on a target position to which a vehicle managed by the vehicle management center heads. Entered. The target position input unit 14 is configured so that the operator of the vehicle information display device 10 performs a target position input operation by displaying a map or the like, or a call from a third party is received. The position information detected at the time may be input as the target position.

Information on the target position input by the target position input unit 14 is sent to the data processing unit 15. In addition, an operation unit 17 that receives an input based on the operation of the operator is provided, and the operation input of the operation unit 17 is also sent to the data processing unit 15.
When the target position is input, the data processing unit 15 transmits information on the target position to the vehicle under management by communication from the communication processing unit 11 and determines the returned information. Then, the target position and the returned information are subjected to data processing, and the display processing unit 13 is caused to execute processing for displaying the information. The display processing unit 13 is a processing unit that controls display on the display unit 16. Note that information received by the communication processing unit 11 may be sent directly to the display processing unit 13. Details of the display processing state relating to the target position will be described later.

Next, the configuration of the in-vehicle device 20 mounted on each vehicle will be described. The in-vehicle device 20 includes a position detection unit 23 and measures the current position of the vehicle as needed. For example, a signal transmitted from a GPS (Global Positioning System) satellite is received, the received signal is analyzed, the current position is measured, and current position information is obtained. When the current position is measured, it may be detected by combining a gyroscope or a vehicle speed pulse.
The obtained current position information is supplied to the display unit 26 and is also supplied to the target position arrival information calculation unit 25 via the vehicle position input unit 24. On the display unit 26, the current position is displayed on the screen. The target position arrival information calculation unit 25 is supplied with the vehicle position data from the vehicle position input unit 24 and the target position data received by the communication processing unit 21 via the data processing unit 27. The target position data and the vehicle position data are absolute position data including, for example, latitude and longitude. The target position data may be received as data such as a place name, a building name, and a road name, and the received data may be converted into absolute position data including latitude and longitude.

By supplying these pieces of information, the target position arrival information calculation unit 25 calculates target position arrival information such as the target position arrival time from the input target position data and the current vehicle position data. The calculated target position arrival information is supplied to the display unit 26 in the in-vehicle device, displayed on the screen, supplied to the communication processing unit 21, and transmitted to the vehicle information display device 10 side.
As the position detection unit 23, the vehicle position input unit 24, the target position arrival information calculation unit 25, and the display unit 26 of the in-vehicle device 20, for example, those configured as a car navigation device can be used as they are.

[2. Example of processing until reaching the target position]
Next, a processing example until the vehicle arrives at the target position in the example of the present embodiment will be described with reference to the flowchart of FIG.
In the example of the flowchart of FIG. 2, the vehicle information display device 10 is set with a target position to which the vehicle is headed, and the target position is instructed from the state in which the target position is instructed to the in-vehicle device 20 of the specific vehicle. The process until the vehicle arrives at the target position is shown. In the flowchart of FIG. 2, the processing in the center-side vehicle information display device 10 and the processing in the vehicle-side in-vehicle device 20 are shown in one flow.
The processing will be described with reference to FIG. 2. First, the communication processing unit 11 of the vehicle information display device 10 transmits target position data to a specific in-vehicle device 20 (step S11), and the target position data is communicated to the in-vehicle device 20. The unit 21 receives (step S12).

When the in-vehicle device 20 receives the target position data, the target position arrival information calculation unit 25 obtains target position arrival information such as an estimated arrival time from the current position indicated by the vehicle position data to the target position indicated by the target position data. Is calculated (step S13). The calculated target position arrival information is transmitted from the communication processing unit 21 to the center side (step S14).
When this target position arrival information is received by the communication processing unit 11 of the vehicle information display device 10 on the center side (step S15), the target position arrival information is sent to the display processing unit 13 and arrives at the screen being displayed on the display unit 16. The target position arrival information such as the predicted time is displayed (step S16). The target position arrival information such as the estimated arrival time is also displayed on the display unit 26 on the in-vehicle device 20 side.

  Thereafter, the target position arrival information calculation unit 25 of the in-vehicle device 20 determines whether or not the target position has been reached (step S17). If the target position has not arrived, the process returns to step S14, and a predetermined constant value is determined. The target position arrival information is transmitted at a cycle. The fixed period is a relatively short time such as 1 minute or 3 minutes. Alternatively, transmission of the target position arrival information may be repeated under some conditions, such as when the current position has changed by a certain distance or more.

FIG. 3 shows a display example on the display unit 16 of the vehicle information display device 10 when the processing of the flowchart of FIG. 2 is performed.
FIG. 3 shows an example in which a vehicle type display 1, a target position display 2, an expected arrival time display 3, a required time display 4, and a distance display 5 are performed on the screen. In this example, different target positions are set for a plurality of vehicles managed by the vehicle management center, and the states of the respective vehicles are displayed in a list.

In the column of vehicle type display 1, “vehicle A”, “vehicle B”... And the type of vehicle are displayed.
In the target position display 2 column, the target position set for each vehicle is displayed. The display of the target position may be a position display such as latitude / longitude, but it is preferable to display the place name or building name in an easily understandable form.
In the column of predicted arrival time display 3, the estimated arrival time transmitted from the in-vehicle device 20 is displayed.
The required time display 4 column displays the required time to the target position. This required time is a required time from the current time to the estimated arrival time. Or it is good also as a total required time from the timing which instruct | indicated the target position with respect to the vehicle-mounted apparatus 20 to the estimated arrival time.
In the column of the distance display 5, the remaining travel distance to the target position is displayed. This travel distance information is transmitted from the in-vehicle device 20 side as information added to the target position arrival information, for example. Alternatively, on the vehicle information display device 10 side, the travel distance may be predicted and displayed from the current position of the vehicle and the target position. Also regarding this travel distance, the total travel distance from the time of setting the target position may be indicated.

In the display shown in FIG. 3, the display information for each vehicle is updated each time the processing of steps S14 to S16 in the flowchart of FIG. 2 is repeatedly executed. Since this update is performed individually for each vehicle, information about each vehicle being displayed as shown in FIG. 3 is updated individually as needed.
Thus, the vehicle arrival efficiency of vehicle management is improved by displaying the estimated arrival time of the vehicle instructing the target position on the display unit 16 of the vehicle information display device 10 provided in the vehicle management center. For example, when a request from a third party to the vehicle management center is a call or the like, and the vehicle is directed to the location of the third party, the center operator views the estimated arrival time of the vehicle on the screen. It is possible to confirm the arrival time to a third party. Conventionally, since the estimated arrival time was only displayed on the display unit on the vehicle-mounted device side, the operator on the center side needs to contact the personnel on the vehicle side by radio telephone etc. and listen to the estimated arrival time. However, there is no need for such processing, and the center side can quickly determine the estimated arrival time. In addition, since the estimated arrival time itself is calculated by the in-vehicle device on each vehicle side, a highly accurate prediction is made in consideration of the actual road running condition and congestion in each vehicle, and the arrival is highly accurate. There is an effect that the estimated time can be grasped on the center side.

[3. Example of vehicle selection processing at the center]
The processing in the flowchart of FIG. 2 shows the processing in a state where the vehicle to be directed to the target position has already been selected. However, in the case of selecting the vehicle to be directed to the target position, for example, as illustrated in the flowchart of FIG. Processing is executed.
The process of the flowchart of FIG. 4 will be described. First, it is assumed that the target position input unit 14 of the vehicle information display device 10 has an input of a target position that turns the vehicle (step S21). The input of the target position may be either automatically input based on some correspondence such as a telephone call or manually input by the operator.
When the target position is input, the data processing unit 15 of the vehicle information display device 10 selects a vehicle within a certain distance from the target position from the current position of each vehicle grasped by the vehicle information display device 10 as a candidate vehicle. (Step S22). Here, it is determined whether there is a vehicle that is responding to the emergency service among the selected candidate vehicles (step S23). If there is a vehicle that is responding to the emergency service, it is excluded from the candidates (step S24). ).

  When candidate vehicles are selected, a command for returning the arrival time to the target position is sent to all of the candidate vehicles. In the in-vehicle device 20 of each vehicle, the target position arrival information calculation unit 25 calculates the arrival time from the current position to the target position, and the information on the calculated arrival time to the target position is transmitted from the communication processing unit 21 to the vehicle. The information is transmitted to the information display device 10 side. However, in this state, only the target position arrival information calculation unit 25 performs calculation, and the target position is not yet set in the in-vehicle device 20.

When receiving the arrival time to the target position, the vehicle information display device 10 displays the expected arrival times of each candidate vehicle in a list in order of the expected arrival time (step S25). A display example at this time will be described later.
Then, the operator of the vehicle information display device 10 performs an operation of selecting a necessary number of vehicles to be directed to the target position from the list display (step S26), and the on-vehicle device of the selected one or a plurality of vehicles. A command to set the target position is issued to 20 (step S27).
The process of transmitting the command for setting the target position in step S27 corresponds to the transmission of the target position data in step S11 of the flowchart of FIG. 2, and thereafter, the process according to the flowchart of FIG. 2 is executed.

FIG. 6 shows an example where the display unit 16 of the vehicle information display device 10 in step S25 displays the expected arrival times of candidate vehicles in a list in order of the expected arrival time.
In this example, a vehicle type display 31, an expected arrival time display 32, a required time display 33, and a distance display 34 are performed.
In the example of FIG. 6, “vehicle A”, “vehicle D”, and “vehicle E” are selected as the estimated arrival times to “target position X”, and the estimated arrival times are displayed in order from the earliest. I'm allowed.
Then, the selection display 35 showing the column of the vehicle to be selected from the displayed candidates is performed. The selection display 35 is selected by an operation by the operator such as clicking the display location of the decision button 36. The selected vehicle is selected as the vehicle to be directed to the target position. From the display screen of FIG. 6, a plurality of vehicles may be selected as vehicles to be directed to the target position.

[4. Example of reselection processing at the center]
Next, an example in which the vehicle is reselected in a state after selecting the vehicle to be directed to the target position will be described.
First, the vehicle information display device 10 determines whether or not it is time to update the predicted arrival time display in a state where the predicted arrival time display as shown in FIG. 3 is being performed (step S31).
If it is determined in step S31 that it is not the update timing, it is determined whether or not the operator of the vehicle information display device 10 has manually performed the latest information acquisition operation. If there is no update operation, the process returns to step S31.

  And when updating a display, it moves to step S33, acquires the newest expected arrival time information from the vehicle which is heading to the target position, and updates the displayed expected arrival time. In addition, although the process of this step S31-S33 is a process supposing updating with the request | requirement from the vehicle information display apparatus 10, the newest arrival time information is automatically updated for every fixed time from the vehicle-mounted apparatus 20 side. The vehicle information display apparatus 10 may be updated when receiving the information.

Then, it is determined whether or not the updated estimated arrival time is later than a predetermined condition (step S34). As a condition here, for example, it is determined whether or not the expected time is delayed more than a certain time such as 10 minutes. Alternatively, it is determined that the time is delayed by a certain ratio or more (for example, 30% or more) with respect to the remaining required time.
When there is a vehicle that is delayed more than the determined condition, whether or not there is an operation input for performing re-selection based on the display that prompts re-selection of the target position on the vehicle information display device 10 Judgment is made (step S35). If there is no operation input for reselection, the process returns to step S31.
If there is an operation input for reselection, the selection screen is displayed again (step S36), and thereafter, the vehicle to be directed to the target position is changed based on the operation on the selection screen.

FIG. 7 is an example of a display prompting reselection of the target position in step S35. In this example, it is assumed that the estimated arrival time of the vehicle A is updated to “17:25”, which is delayed by 10 minutes, in the state where the estimated arrival time display shown in FIG. 3 is performed. At this time, a delay warning display 41 such as blinking the estimated arrival time delayed by 10 minutes is performed and a reselection button 42 is displayed on the screen. When the operator performs an operation input to select the reselect button 42, for example, a list of candidate vehicles shown in FIG. 6 is displayed, and a vehicle suitable for moving to the target position again is selected. Can be done.
In this way, when a delay in the estimated arrival time occurs, the center can quickly determine this, so that it is possible to quickly change the vehicle, report delays to a third party, etc., and achieve good vehicle management. Has the effect of being able to do.

[5. Modified example]
Note that the processing configurations and display examples described in the above-described embodiments are merely examples, and modifications and changes can be made without departing from the scope of the present invention.
For example, as an example of display, an example is shown in which the arrival time of each vehicle is displayed in the form of a table. For example, the current position of each vehicle is indicated by displaying a road map, etc. Information such as estimated arrival time may be displayed at the location of the vehicle.

  Further, the configuration of each processing unit of the vehicle information display device 10 and the in-vehicle device 20 shown in FIG. 1 is a configuration viewed from the functions realized by the devices, and each device necessarily includes such a processing unit. Not exclusively. For example, a program (software) for performing the processing of the present invention may be installed in an information processing device including a computer device and a display, and the same processing may be performed.
