However, the function for setting the power saving mode cannot be determined only from the state of the mobile terminal, and it is necessary to comprehensively determine the surrounding environment of the vehicle in which the mobile terminal is brought in and the state of the mobile terminal. For example, when it is predicted that the state in which the reception level of the mobile terminal is lower than the predetermined level will continue for a predetermined period from the surrounding environment of the vehicle, the mode is automatically switched to the power saving mode for turning off the function related to communication in the mobile terminal, When the communication state is improved from the state, it is desired to immediately return to the original operation mode.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to obtain an in-vehicle device that can appropriately switch the mode of a mobile terminal brought into the vehicle.

  The in-vehicle device according to the present invention is set in a communication unit that communicates with a mobile terminal brought into the vehicle, a mobile terminal state acquisition unit that acquires terminal information indicating the state of the mobile terminal by the communication unit, and a mobile terminal. Based on the mode storage unit that stores the power mode, the vehicle surrounding information indicating the surrounding environment of the vehicle, and the terminal information acquired by the mobile terminal state acquisition unit, among the modes stored in the mode storage unit, set to the mobile terminal The mobile terminal state management unit for selecting the mode to be selected, determining the timing for setting the selected mode in the mobile terminal and the timing for returning to the original mode, and the timing for determining the instruction information for changing the mode by the mobile terminal state management unit And a change mode instructing unit for switching the mode by transmitting to the portable terminal by the communication unit.

At this time, the portable terminal 2 is also waiting for an event (8 steps ST1a-1).
Next, the portable terminal state acquisition unit 12 periodically sends terminal information (information indicating the state of the portable terminal 2 in the currently set mode) to the portable terminal 2 via the short-range wireless communication unit 11. A request is made (step ST2a).
The control unit 20 of the mobile terminal 2 transmits its terminal information (information indicating the state in the currently set mode) via the short-range wireless communication unit 21 in response to a request from the in-vehicle device 1 ( Step ST2a-1).

The portable terminal state management unit 101 acquires the terminal information of the portable terminal 2 received via the short-range wireless communication unit 11 and the portable terminal state acquisition unit 12 (step ST3a).
Next, the portable terminal state management unit 101 uses the display unit 16 or the audio output unit 17 to inquire the user whether the operation of the portable terminal 2 can be automatically switched (step ST4a).

When there is a reply that the automatic operation switching is not performed (step ST4a; NO), the mobile terminal state management unit 101 uses the display unit 16 or the audio output unit 17 to store the mobile terminal 2 in the mode storage unit 102. The user is inquired whether the mode can be changed to the registered mode (step ST5a).
When there is a reply that the change is not made (step ST5a; NO), the operation management mode is ended (step ST6a).
When there is an answer to the change (step ST5a; YES), the change mode instruction unit 100 requests the mobile terminal 2 to change the mode via the short-range wireless communication unit 11 in accordance with an instruction from the mobile terminal state management unit 101. To do. The portable terminal 2 changes to the said mode according to this (step ST7a).

  When there is a reply that the operation may be automatically switched (step ST4a; YES), or when the mobile terminal 2 is changed to the registered mode in step ST7a, the mobile terminal state management unit 101 The current position of the vehicle is acquired from the position information acquisition unit 15 (step ST8a). Furthermore, the portable terminal state management unit 101 confirms whether or not a destination is set from the car navigation unit 13 (step ST9a).

When the destination is set (step ST9a; YES), the mobile terminal state management unit 101 acquires vehicle surrounding information related to the travel route (guide route) from the car navigation unit 13, and based on the vehicle surrounding information, When there is a place in the travel route that can be outside the reception area of the telephone network communication unit 22a (for example, a long tunnel longer than a predetermined distance, a mountain that travels for a predetermined time, etc.), Is obtained and stored (step ST10a).
Thereafter, the mobile terminal state management unit 101 enters and exits a place that can be an out-of-reception area obtained from the vehicle surrounding information, so that the mode stored in the mode storage unit 102 for the mobile terminal 2 is stored. From within, a mode in which the function of the telephone network communication unit 22a is stopped (hereinafter referred to as “partial off mode”), or all communication functions except the short-range wireless communication unit 21 are turned off (power of the communication units 22a to 22d) Mode) (hereinafter referred to as all-off mode).

The control unit 20 of the portable terminal 2 periodically checks the reception level of the telephone network communication unit 22a, and when the reception level of the telephone network communication unit 22a decreases to a certain level, Information is transmitted to the in-vehicle device 1 as terminal information (step ST10a-1).
The portable terminal state management unit 101 recognizes that the vehicle has approached the predetermined area outside the reception area specified in step ST10a and that the reception state of the telephone network communication unit 22a has deteriorated from the terminal information of the portable terminal 2. Then, it is determined that the reception state of the telephone network communication unit 22a has deteriorated due to the vehicle approaching the out-of-reception area, and it is time to set the partial off mode or the full off mode selected as described above. decide. Thereby, the portable terminal state management unit 101 instructs the change mode instruction unit 100 to transmit a request for setting the partial off mode or the full off mode.
