This flow is performed in a timely manner, for example, at a constant time period after the telematics control unit 100 and other devices connected to the vehicle bus 200 are started to a certain extent.
- control unit 110 identifies one SIM interface having a lower priority among unprocessed SIM interfaces (step S101). Specifically, the control unit 110 refers to the SIM connection condition storage unit 111 and identifies an unprocessed connection SIM 111B having a low priority 111A.
- control part 110 determines whether the communication conditions of the specified SIM interface are satisfy
- step S102 When the communication condition of the specified SIM interface is satisfied (“Yes” in step S102), the control unit 110 selects the SIM interface as an activation target (step S103). Then, the process proceeds to step S104.
- the control unit 110 determines whether or not the identified SIM interface is the highest-order SIM interface (step S104).

It can be said that it is possible.

This flow is performed after the telematics control unit 100 and other devices connected to the vehicle bus 200 are activated to a certain degree, and after the SIM interface is activated so as to be communicable by the SIM selection process, by the control unit 110 in a timely manner.
- the SIM interface whose vehicle information satisfies the service start condition 111D is selected and started.
- the control unit 110 determines whether there is a higher-order SIM interface that is in communication or has ended communication (step S201). Specifically, the control unit 110 terminates communication in the past within a predetermined time from the time of the processing for the SIM interface having a higher priority than the SIM interface activated so as to be communicable, or the processing time Whether or not the communication is in progress is determined. In any state, the control unit 110 ends the communication process. This is because it is not a situation in which communication with a SIM interface having a lower priority is actively required, that is, an accident or theft may occur.
- Step S201 the control unit 110 determines whether or not there is a peer SIM interface in communication. Specifically, the control unit 110 determines whether there is a SIM interface that is in communication at the time of processing and is a peer SIM interface that has no priority.
- control unit 110 waits until the communication of the peer SIM interface in communication ends (step S203). And control part 110 will advance processing to Step S206 mentioned below, if communication of the peer SIM interface in communication is completed.
- control unit 110 determines whether there is a lower SIM interface in communication (step S204). Specifically, the control unit 110 determines whether there is a SIM interface that is communicating at the time of processing and has a lower priority order.
- control unit 110 advances the processing to step S206 described later.
- step S204 If there is a lower-order SIM interface in communication (“Yes” in step S204), the control unit 110 performs an interrupt process to the lower-order SIM interface described later (step S205). And the control part 110 advances a process to step S206 mentioned later.
- control part 110 implements communication by the selected SIM interface (step S206).
- the telematics control unit 100 does not perform the communication process using the lower SIM interface when the communication of the higher SIM interface has been completed or is in communication. Further, during the communication of the peer SIM interface, the communication is started after the end of the communication by the SIM interface during the communication. In addition, during the communication of the lower SIM interface, the communication is started with an interrupt. By doing so, since communication with a higher priority SIM interface is prioritized, communication with a higher urgency upper SIM interface is preferentially performed in a highly urgent situation. That is, when the vehicle information indicates a predetermined emergency state, it can be said that the SIM interface for performing emergency support communication can be made communicable.
- FIG. 6 is a flowchart showing an interrupt process to the lower SIM interface performed by the telematics control unit 100. This flow is performed after the telematics control unit 100 and other devices connected to the vehicle bus 200 are activated to a certain degree, and after the SIM interface is activated so as to be communicable by the SIM selection process, by the control unit 110 in a timely manner. This is started when a SIM interface whose vehicle information satisfies the service start condition 111D is selected and a SIM interface lower than the selected SIM interface is already communicating.
- control unit 110 disconnects the line of the lower SIM interface that is in communication (step S301).
- control unit 110 disconnects the logical port between the modem 130 and the control unit 110 (step S302).
- the SIM switching unit 131 switches to the SIM interface that interrupts the SIM interface (step S303). Specifically, the SIM switching unit 131 disconnects the lower SIM interface from the modem 130, and interrupts and connects the selected SIM interface to the modem 130.
- the SIM switching unit 131 performs location registration on the network of the SIM interface to be interrupted (step S304). Specifically, the SIM switching unit 131 instructs the interrupted SIM interface to transmit location registration information toward the network of the SIM interface to be interrupted.
- the interrupted SIM interface receives the position information from the position information receiving unit 140, and transmits the position information as registration information to the nearest base station or the like as the registration information transmission destination.
- control part 110 implements the process of step S305-step S307 mentioned later in parallel with implementation of step S303 and S304.
- the control unit 110 performs a termination process for the application in communication using the lower SIM interface (step S305). Specifically, the control unit 110 delivers information that prompts the end of the process, for example, information on the end of communication, to the application that has used the lower-order SIM interface that performed the communication disconnected in step S301.
- control part 110 registers DTC (error code) (step S306). Specifically, the control unit 110 identifies an error code that causes communication to end and registers it as a DTC.
- control part 110 cuts off the power supply of the device which is not used in the SIM interface to interrupt (step S307). Specifically, the control unit 110 turns off the power supply for a predetermined electronic component predetermined for each SIM interface. For example, in the case of an accident, this is to eliminate unnecessary power consumption. In other words, when the communication using the SIM interface having a lower priority than the SIM interface that performs the interrupt is started, the SIM switching unit 131 disconnects the communication using the SIM interface where the communication is started and interrupts the communication. It can be said that the control unit 110 terminates the processing unit that has performed communication using the lower priority SIM interface in response to starting communication using the SIM interface to be performed.
- the above is the operation of interrupt processing to the lower SIM interface.
- the interrupt operation to the lower SIM interface it is possible to perform SIM interrupt processing by executing SIM interface switching processing and communication termination processing in parallel with each other. As compared with the process of switching the SIM interface after waiting, the interrupt can be performed quickly.
