[0009] Hereinafter, an embodiment of the present disclosure will be described with reference to the drawings.

[0010] In each figure, the same or corresponding parts are denoted by the same reference numerals. In the description of the present embodiment, the description of the same or corresponding parts will be omitted or simplified as appropriate.

[0011] Referring to FIG. 1, the outline of the present embodiment will be described.

[0012] The information presentation device 20 is a computer mounted on the vehicle 12. That is, the information presentation device 20 is provided in the vehicle 12.

[0013] The vehicle 12 is any type of automobile such as, for example, a gasoline vehicle, a diesel vehicle, a hydrogen vehicle, an HEV, a PHEV, a BEV, or an FCEV. "HEV" is an abbreviation for hybrid electric vehicle. "PHEV" is an abbreviation for plug-in hybrid electric vehicle. "BEV" is an abbreviation for battery electric vehicle. "FCEV" is an abbreviation for fuel cell electric vehicle. The vehicle 12 is driven by the driver 11 in this embodiment, but the driving may be automated at any level. The level of automation is, for example, any one of levels 1 to 5 in the SAE level classification. "SAE" is the abbreviation of Society of Automotive Engineers. The vehicle 12 may be a vehicle dedicated to MaaS. "MaaS" is an abbreviation for Mobility as a Service.

[0014] The information presentation device 20 determines whether or not there is a person inside the vehicle 12, that is, whether or not a person is trapped inside the vehicle 12, in response to a locking operation outside the vehicle 12 that may include the in-lock of the vehicle 12. When the information presentation device 20 determines that a person is trapped inside the vehicle 12, the information presentation device 20 notifies the trapped person of the procedure for unlocking and opening the door via a display or a speaker inside the vehicle 12.

[0015] According to the present embodiment, since the procedure for unlocking and opening the door is notified to the person trapped inside the vehicle 12, the probability that the person can unlock and open the door by themselves and escape from the vehicle 12 is increased.

[0016] When the information presentation device 20 determines that a person is trapped inside the vehicle 12, the information presentation device 20 may start a call between the portable terminal of the driver 11 and the information presentation device 20.
