[0036]
As shown in FIG. 3, the portable communication device 10 is provided with a pendulum sensor 44 that detects its own vibration, and a vibration value detected by the pendulum sensor 44 is counted by a timer 45 by a counter 45 every predetermined time. The vibration value is counted and compared with a preset threshold value by the comparator 47. And when the vibration value by the pendulum sensor 44 exceeds a threshold value, it transmits to the vehicle-mounted communication device 20 as vibration information.
[0037]
The in-vehicle communication device 20 determines whether the mobile communication device 10 is moving or stopped from the vibration information received from the mobile communication device 10 and displays the determination result on the display.

[0040]
The following communication operations can be applied as a master or slave regardless of the combination of portable communication devices, on-vehicle communication devices, or on portable communication devices and on-vehicle communication devices. This system is configured so that the location and status of the can be easily confirmed.
[0041]
FIG. 5 shows a communication partner authentication procedure by ID verification, and FIG. 6 shows a communication partner location information acquisition procedure.
<Authentication of communication partner>
In step S1 of FIG. 5, if there is another communication device within the communicable range (YES in step S1), it is determined in step S3 whether the address of the counterpart communication device has been registered.
[0042]
If it is checked in step S3 (YES in step S3), data is synchronized in the link format in step S5.
[0043]
In step S7, master or slave information is acquired.
[0044]
If it is determined in step S9 that it is a master, the process proceeds to step S11. If it is a slave, the process proceeds to step S29.
[0045]
In steps S11 to S15, a basic ID request is sent to the slave, and after receiving the basic ID from the slave, the received ID is checked against its own ID.
[0046]
If the IDs do not match in step S15, they are added to the checked address in step S27 and the process returns.
[0047]
If the IDs match in step S15, an auxiliary ID request is received from the slave in steps S17 to S21, the auxiliary ID is transmitted, and the reception of the auxiliary ID verification result from the slave is awaited.
[0048]
After receiving the verification result of the auxiliary ID from the slave in step S21, the verification result is determined in step S23, and if it does not match, it returns to the checked address in step S27. Communication of location information is started.
[0049]
In synchronization with the master operation, the slave receives a basic ID request from the master in steps S31 to S37, transmits the basic ID to the master, creates an auxiliary ID request, and transmits the auxiliary ID request to the master.
[0050]
In steps S39 and S41, if the auxiliary ID is received from the master before a timeout occurs after a predetermined time has elapsed since the transmission of the auxiliary ID to the master, the auxiliary ID received in step S43 is checked against its own auxiliary ID.
[0051]
If a time-out occurs in step S39 or if the auxiliary ID does not match in step S43, it is added to the checked address in step S49 and the process returns.
[0052]
If the IDs match in step S43, the collation result is transmitted to the master in steps S45 and S47, and communication of position information with the master is started.
[0053]
Note that the authentication by the ID verification may be performed by at least one of the master and the slave.
<Acquisition of location information>
Acquisition of the location information of the communication partner is realized by two-way communication between the master and the slave authenticated by ID verification. If the master acquires the attribute information from the slave in step S51 shown in FIG. 6 (in step S51). YES), slave attribute information is displayed in step S53 (see display A in FIGS. 7 and 8).

In the case of communication between in-vehicle communication devices as in the display examples of the in-vehicle communication devices in FIGS. 7 and 8, this attribute information includes ID and name (display A) on the map screen such as a car navigation device, Attached information such as vehicle characteristics such as the color of the vehicle, manufacturer name, vehicle type, partner's position (display B), partner's state (display C), and partner's direction (display D) is displayed. The display on the portable communication device is the same.
[0055]
If the attribute information is not acquired from the slave in step S51 (NO in step S51), or if the attribute information of the slave is displayed in step S53 and then the position information is acquired from the slave in step S55 (YES in step S55). In step S57, the slave position information is displayed.
[0056]
The position information is displayed as a display E on the map screen of the in-vehicle communication device exemplified in FIGS. 7 and 8 and the map screen of the portable communication device exemplified in FIGS. 9 and 10.
[0057]
In step S59, the master detects the operation of the confirmation button for informing the slave that the position and attribute of the slave have been confirmed, and transmits a confirmation signal to the slave in step S61 if the confirmation button is turned on.
[0058]
In step S63, the operation of the end button for ending the exchange of position information and attribute information by communication with the slave is detected, and the processing from step S55 is repeatedly executed until the end button is turned on.
[0059]
When the slave is a portable communication device and the received attribute information includes vibration information from the pendulum sensor, the master determines from the vibration information whether the slave is moving or stopped. A character indicating that the slave is a portable communication device and is moving as indicated by display C1 of FIG. 7 or a character indicating that the slave is a portable communication device and is stopped as indicated by display C2 of FIG.

[0061]
Thus, when displaying the status of the master at the slave, a character indicating that the master is moving is displayed as shown by display C3 in FIG. 9, or the master is stopped as shown by display C4 in FIG. Displays a character indicating that it is inside.
[0062]
The communication data amount when the master or slave is stopped may be set to be larger than the communication data amount during movement, and it may be determined whether it is moving or stopped from the change in the communication data amount. In this case, it is possible to prevent a decrease in communication reliability due to the influence of radio waves by transmitting only necessary data during movement.
[0063]
Further, as shown in FIG. 11, on the master map screen, the range in which communication with the slave is possible centered on the current position at the same time as the slave position information (display F1 in FIGS. 7 and 8, display in FIG. 11). F1, F2, and F3) may be displayed.
[0064]
In addition, when transmitting the current position from the slave to the master, the slave simultaneously transmits identification information of an object (such as a traffic light) that is within a predetermined distance range from the current position of the slave, and the master combines with the identification information of the object. Slave position information may be displayed.
[0065]
Furthermore, if the master is an in-vehicle communication device, it sends its location information to the slave along with the map screen of the car navigation device, and the slave displays at least the portion of the map screen received from the master. To do.
[0066]
In addition, the master (or slave) transmits predetermined operation information based on a user operation, and the slave (or master) that has received the predetermined operation information receives this operation so that the other party can be easily confirmed when the communication partner approaches. An operation corresponding to the predetermined operation information (such as flashing of a vehicle light, horn operation, vibration of a portable communication device) is executed. At this time, at least one of the master and the slave may transmit periodic predetermined operation information, and the slave or master that has received the predetermined operation information may execute an operation corresponding to the information.
[0067]
Further, the distance to the communication partner is detected by at least one of the master and the slave, and if the distance to the communication partner approaches within a predetermined distance range, this is notified by a change in sound, display screen, or vibration.
