Further, more specific content can be notified regarding a predetermined state according to the user's request.

(Embodiment)
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

<Configuration>
FIG. 1 shows a functional block diagram of a vehicle state presentation system 10 according to the present embodiment. Vehicle state presentation system 10 includes a vehicle state presentation device 100 and a vehicle 200.

  The vehicle state presentation device 100 is a small-sized device including an ear attachment unit attached to the user's ear. Vehicle state presentation apparatus 100 includes a user authentication unit 101, a sound emission unit 102, an input unit 103, a state detection unit 104, a first communication unit 105, a notification unit 106, and a first authentication unit 107. The sound emitting unit 102 is attached to the user's ear and includes a speaker capable of emitting sound in the user's ear canal. The input unit 103 includes an authentication microphone that picks up echo sound in the user's ear canal and a speech microphone that picks up the user's speech sound. In addition, it has a function of recognizing speech from the user's voice picked up. As an example, the user authentication unit 101 emits an authentication sound from the sound emission unit 102 to the user's ear canal, acquires the echo with the authentication microphone of the input unit 103, and registers in advance the characteristics of the echo. Authenticate the user by comparing it with the characteristics of the regular user's echo. The first communication unit 105 wirelessly communicates with the vehicle 200, and the state detection unit 104 detects a state notification of the vehicle based on the communication result. The sound emitting unit 102 also emits a sound for various notifications to the user. The notification unit 106 generates notification content for the user as a sound based on the input from the user to the input unit 103 and causes the sound emitting unit 102 to emit sound.

  Vehicle 200 includes a state monitoring unit 201, a second authentication unit 202, and a second communication unit 203. The second communication unit 203 wirelessly communicates with the vehicle state presentation device 100. When the distance between the vehicle 200 and the vehicle state presentation device 100 is within the distance that allows wireless communication with each other, the second authentication unit 202 transmits the first of the vehicle state presentation device 100 via the second communication unit 203. The authentication unit 107 executes a communication sequence for authentication. As an example of authentication, the second authentication unit 202 compares the identifier of the vehicle condition presentation device 100 with the identifier of the normal vehicle condition presentation device associated with the own vehicle in advance, thereby the vehicle condition presentation device 100 is identified. Certify. The state monitoring unit 201 monitors the states of various devices (not shown) of the vehicle 200, and notifies the vehicle state presentation device 100 via the second communication unit 203 when a predetermined state occurs. Note that the vehicle state presentation device 100 and the vehicle 200 may each include a control unit that appropriately controls the operation of the above-described units.

  As described above, if the vehicle state presentation device 100 authenticates the user and the vehicle 200 authenticates the vehicle state presentation device 100, the combination of the vehicle and the authorized user can be guaranteed, which is preferable. The above-described authentication method is an example, and may be modified. For example, the first authentication unit 107 of the vehicle state presentation device 100 may acquire the identifier of the vehicle 200 by communication, and may authenticate the vehicle based on this. FIG. 2 shows an example of a range 500 in which the vehicle 200 and the vehicle state presentation device 100 can wirelessly communicate with each other. The range 500 is, for example, a range of about 10 m or less from the vehicle.

<Processing>
FIG. 3 is a sequence diagram for explaining the processing of the vehicle 200 and the vehicle state presentation device 100 when a predetermined state occurs. This process will be described with reference to FIG.

  Step S1: The state monitoring unit 201 of the vehicle 200 monitors the states of various devices based on, for example, information from various control units installed in the vehicle, and detects this when a predetermined state occurs. . Here, the predetermined state is, for example, a state in which one or more conditions defined in advance are satisfied. For example, when the door lock operation is performed when the ignition is off and any of the doors is open, a half door state is established as a predetermined state.

  In addition, it is variously definable as a state of a vehicle. For example, when the vehicle speed is 0 and the key outside the vehicle is other than ignition off, when the driver's seat door is changed from the open state to the closed state, the key bring-out state is established as a predetermined state. In addition, when the door lock operation is performed when the ignition is off, the key vehicle interior and all the doors are in the closed state, the key closing state is generated by setting the predetermined state.

  Step S2: The state monitoring unit 201 of the vehicle 200 notifies, via the second communication unit 203, that the vehicle state presentation device 100 has generated a predetermined state.

  Step S3: The state detection unit 104 of the vehicle state presentation device 100 receives, from the vehicle 200, a notification indicating that a predetermined state has occurred, via the first communication unit 105.

  Step S4: The sound emitting unit 102 of the vehicle state presentation device 100 emits sound to the user. The sound to be emitted is, for example, a buzzer sound such as "pee".

  Step S5: The user listens to the sound emitted by the vehicle state presentation device 100.

  Step S6: The user performs a predetermined input on the vehicle state presentation device 100, which means to inquire what kind of state the sound heard specifically represents. As an example, the user utters "What is it now?"

  Step S7: The input unit 103 of the vehicle state presentation device 100 receives the speech of the user as an input, and analyzes the contents by the speech microphone that collects the speech sound of the user. If such an input is not performed within a predetermined period from the sound emission in step S4, the subsequent steps S8 and S9 are not executed.

  Step S8: Based on the analysis content in step S7, the notification unit 106 of the vehicle state presentation device 100 determines that it is a predetermined input for inquiring what kind of state it represents, and the voice (specifically, the state) For example, "a half door" is emitted from the sound emission unit 102.

  Step S9: The user can listen to the sound emitted by the vehicle state presentation device 100, and can specifically know the contents of the generated state. This completes the sequence.

  The input unit 103 of the vehicle state presentation device 100 may include a motion sensor, a touch sensor, and the like. The input method by the user in step S6 may not be based on a predetermined word, but may be based on a predetermined gesture such as waving a head or striking the vehicle state presentation device 100.

  Further, the sound emitted by the sound emitting unit 102 of the vehicle state presentation device 100 in step S4 is not limited, but is preferably concise. The sound may be the same regardless of the type of the generated state, or the type may be identifiable by the length of the sound, the number of repetitions, or the like.

  Note that the vehicle state presentation device 100 may have a configuration in which, for example, all the components are included in the ear attachment unit attached to the user's ear, or at least the sound emitting unit 102 is included in the ear attachment unit, and the other components are included. The configuration may be included in a portable terminal device such as a smartphone, and the ear attachment unit and the portable terminal device may communicate wirelessly or by wire. Moreover, although it is preferable to perform user authentication by the above-mentioned echo, it is not essential.

<Effect>
According to the above sequence, the predetermined state of the vehicle can be notified only to the user by sound from the sound emitting unit 102 worn on the ear. This makes the notification more noticeable to the user. In addition, since the notification can not be heard by a third party, it is not annoying and security can be improved. Further, when there is a predetermined input by the user, more specific content can be notified. However, if the user does not want to be notified of a voice representing a specific content and does not make a predetermined input, such as when the user intends to put in a predetermined state or thinks about the content, the specific Since the notification of the content is not performed, the burden can be reduced.

  The present invention can be viewed not only as a vehicle state presentation device and a system including the same and a vehicle, but also as a method executed by one or more computers provided with a processor and a program thereof.

  As a reference example, instead of or in addition to the sound output by the vehicle state presentation device 100 in the above-described steps S4 and S8, an output device such as a vehicle external buzzer, a meter, and a navigation device may be used as appropriate. It is also conceivable to guide the user in an orderly manner and cope with the generated state while suppressing unnecessary output in response to the user's reaction.

  The present invention is useful for an apparatus for notifying a user of the state of a vehicle or the like.
