It is determined whether or not the authentication data confirmation is OK (S103). If the authentication is not OK, this process ends. If the authentication is OK, the control device selecting unit 23 determines the target vehicle-mounted device from the control data (S104). ).

Then, the control data transmission unit 24 converts the control data into a form of communication with the vehicle-mounted device (S105), and the control data transmission unit 24 transmits the control data to the vehicle-mounted device (S106). Next, the processing in the in-vehicle device is performed (S10
7) The processing output of the in-vehicle device is input to the in-vehicle device control device 2 (S108), and the output control unit 25 converts the output into a data format that can be handled by the communication unit 22 (S109). Then, the output data is transmitted to the remote terminal 1 using the communication unit 20 and the communication device 4 (S110).

§5: Description of Example 4 (1): Description of System FIG. 13 shows a system configuration diagram of Example 4. Hereinafter, a specific configuration of Example 4 will be described with reference to FIG. Example 4
Is an example of a system in which the output destination of the in-vehicle device connected to the in-vehicle device control device 2 can be switched between the inside of the vehicle and the terminal 1 at a remote location.

In this system, when an operation is performed on the terminal 1 at a remote location, the control device selecting section 23 sets the target device to
It is recorded (registered) in the control device list 29. When there is an output from the vehicle-mounted device, it is determined whether or not the device is from a device recorded (registered) in the control device list 29. If the device is recorded, the output control unit 25 and the communication unit 2
2 to a remote terminal 1.

If the device is not recorded in the control device list 29, it is output to an output device (for example, the speaker 32, the display 31, the amplifier 30, etc.) in the vehicle. Since the output from each in-vehicle device is connected to a separate input terminal of the in-vehicle device control device 2 for each device, the correspondence between the input terminal and the in-vehicle device is set in advance, and the input terminal from which the input terminal is input is determined. You can identify it if you know it.

When the in-vehicle device control device 2 and the in-vehicle device are connected by a communication method such as a wireless LAN that is commonly used by a plurality of in-vehicle devices, an identification number (for example, wireless The identification is performed by an IP address or the like in the case of a LAN). The other configuration is the same as the basic system of FIG.

(2): Description of Terminal Processing in System of Example 4 FIG. 14 is a flowchart of terminal-side processing of Example 4. Hereinafter, the terminal-side processing of Example 4 will be described with reference to FIG.
In addition, S121 to S128 indicate each processing step.

First, in the remote terminal 1, the remote control unit 1
In step 3, an image for initial control is created (S121) and displayed on the display screen of the output device 11. The user inputs control using the input device 10 while viewing this screen (S12).
2). Next, the remote control unit 13 creates remote control data in accordance with the input (S123), and the communication unit 12 and the communication device 3
Is used to transmit the output data to the in-vehicle device control device 2 (S124).

Then, it is determined whether or not there is communication from the in-vehicle equipment control device 2 (S125). If there is communication from the in-vehicle device control device 2 in this way, output data is received through the communication device 3 and the communication unit 12 (S126), and is output to the output device 11 by the data output unit 14 (S127). And control (app)
Is determined (S128), and if the control is not completed, the process proceeds to S122. If the control has been completed, this process is completed.

(3): Description of Processing of In-Vehicle Equipment Control Device in System of Example 4 FIG. 15 shows a processing flowchart (part 1) of the in-vehicle equipment control device of Example 4.

First, it is determined whether or not there is communication from the remote terminal 1 (S131). If there is no communication, the process waits as it is. If there is communication, the remote control data is transmitted through the communication device 4 and the communication unit 22. It receives (S132). The control device selection unit 23 determines the target in-vehicle device control device from the control data (S133), and determines whether or not to start the control (S13).
4).

As a result, if the control is to be started, it is registered in the control list, and it is determined whether the control is to be ended (S136). However, if the control is not started, the process proceeds to S136 without performing the process of S135. If the control is completed in the process of S136, the control device list 29 is deleted (S137), and the control data transmission unit 24 converts the control data into a communication form to the in-vehicle device (S138). But,
If the control is not completed in the process of S136, the process proceeds to the process of S138 without performing the process of S137.

Next, control data is transmitted to the on-vehicle device by the control data transmitting unit 24 (S139), and the processing on the on-vehicle device is performed (S140). Then, the processing output of the in-vehicle device is input to the in-vehicle device control device 2 (S141), and it is determined whether or not the device is registered in the control device list 29 (S14).
2).

As a result, if the device is registered in the control device list 29, the output control unit 25 converts the data into a data format that can be handled by the communication unit 22 (S143). Then, the output data is transmitted to the terminal 1 at the remote location (S144). However, if it is not registered in the control device list 29 in the process of S142, it is set as the in-vehicle output (S145).
