[0015] [Figure 1] FIG. 1 is a configuration diagram of a mobile object control device. [Figure 2] FIG. 2 is an explanatory diagram of customization information. [Figure 3] FIG. 3 is a flowchart of the setting process of the display unit and the settable equipment by the mobile object control device. [Figure 4] FIG. 4 is a timing chart of the setting process of the display unit and the settable equipment by the mobile object control device. DETAILED DESCRIPTION OF THE INVENTION

[0016] [1. Configuration of mobile control device] The configuration of a mobile body control device 1 of this embodiment will be described with reference to Fig. 1. The mobile body control device 1 is mounted on a vehicle 50, which corresponds to a mobile body of the present disclosure. The vehicle 50 is provided with a meter 51, a HUD (Head Up Display) 52, and a touch panel 53 such as a DA (Display Audio) that are visible to a user of the vehicle 50.

[0017] Vehicle 50 is equipped with an electric seat 70, left and right door mirrors 71, 72, a steering wheel 73, speakers 74, and an air conditioning unit 90, which correspond to the configurable equipment of the present disclosure. Vehicle 50 is also equipped with an in-vehicle camera 80 that captures images of the interior of the vehicle, exterior cameras 81, 82, 83, 84 that capture images of the surroundings on the front, rear, left and right sides of vehicle 50, a communication unit 91, an ignition (IG) switch 60, an operation panel 61 for changing the set temperature of air conditioning unit 90, etc., a door mirror switch 62 for changing the angle of door mirrors 71, 72, and a seat switch 63 for changing the position (forward / backward position, reclining angle) of electric seat 70.

[0018] The mobile object control device 1 is a computer unit configured with a processor 10, a memory 20, etc. Operation signals from an IG switch 60, an operation panel 61, a door mirror switch 62, a seat switch 63, and a touch panel 53 are input to the mobile object control device 1. In addition, images captured by an in-vehicle camera 80, images captured by external cameras 81, 82, 83, and 84, and data received by a communication unit 91 are input to the mobile object control device 1.

[0019] The control signals output from the mobile body control device 1 control the display state of the meter 51, HUD 52, and touch panel 53, the position of the electric seat 70, the angle of the door mirrors 71, 71, the volume of the alarm sound (corresponding to the specified sound in this disclosure) output from the speaker 74, the set temperature of the air conditioning device 90, etc.

[0020] The memory 20 stores a control program 21 for the mobile object control device 1 and user data 22. As shown in FIG. 2, the user data 22 stores personal data of multiple specific users who are registered with the vehicle 1. The personal data stores a user ID, a facial image of the specific user, and customization information set by the specific user, such as the display mode settings for the meter 51 and HUD 52, the volume of the alarm sound output from the speaker 74, the temperature of the air conditioning device 90, and the position settings for the power seat 70. The alarm sound corresponds to the predetermined sound in the present disclosure, and the volume corresponds to the output mode of the predetermined sound in the present disclosure. The output mode of the predetermined sound may be not only the volume but also the tone, sound output pattern, etc.

[0021] The specific user sets the display mode of the meter 51, the volume of the alarm sound from the speaker 74, and the set temperature of the air conditioning unit 90 by operating the operation panel 61, the touch panel 53, or a switch (not shown) provided on the steering wheel 73, and sets the position of the electric seat 70 by operating the seat switch 63, and the customization information for the specific user is updated in accordance with these setting operations.

[0022] The display state settings of the meter 51 include settings of the display language, display color, display angle, brightness, character size, display items, display design, etc. The settings of the HUD 52 include settings of the display position, tilt, brightness, character size, display items, etc. Figure 1 shows a situation in which a specific user U approaches a vehicle 50 and gets on (boards) the vehicle 50.

[0023] The processor 10 reads and executes the control program 21 to function as a user identification unit 11, a customization information acquisition unit 12, a setting control unit 13, a standby time change acceptance unit 14, and a standby time setting unit 15.

[0024] The user identification unit 11 identifies a specific user U outside the vehicle 50 by comparing a facial image of a person extracted from an image captured by the exterior cameras 81, 82, 83, and 84 with the facial image of the specific user recorded in the user data 22. The user identification unit 11 also identifies a specific user U who is in the vehicle 50 by comparing an image of a person extracted from an image captured by the interior camera 80 with the facial image of the specific user recorded in the user data 22. Note that whether a person is a specific user U may also be identified based on biometric information other than a facial image, such as an iris or fingerprint, or ID information transmitted from a communication terminal 100 carried by the person. Alternatively, the user identification unit 11 may identify a specific user U based on a user name selected by operating the touch panel 53 or the like, or based on the result of comparing the entered password with a password recorded in association with the selected user name.

[0025] The customization information acquisition unit 12 acquires customization information for the specific user U by referring to the user data 22. Of the customization information, the setting states of the display modes of the meter 51 and the HUD 52 correspond to a first setting state in the present disclosure, and the setting states of the volume of the alarm sound, the set temperature of the air conditioner 90, and the position of the electric seat 70 correspond to a second setting state in the present disclosure.

[0026] The setting control unit 13, which will be described in detail later, executes a first control to change the display mode settings of the meter 51 and the HUD 52 and a second control to change the volume of the alarm sound, the set temperature of the air conditioner 90, and the position of the power seat 70, based on the customization information of the specific user U, when the specific user U starts using the vehicle 50. The setting control unit 13 first starts the second control, and then starts the first control when a predetermined waiting time Tw (see FIG. 4, described later) has elapsed since the start of the second control.

[0027] In addition, if the user identification unit 11 recognizes a specific user U who is outside the vehicle 50, the process of executing the first control may not be performed when the waiting time Tw has elapsed after the second control is started by the setting control unit 13.

[0028] The standby time change receiving unit 14 changes the standby time Tw in response to an operation of the operation panel 61 or the like by the specific user U. The standby time setting unit 15 sets the standby time Tw in response to the time required for the second control. For example, when changing the position of the electric seat 70 through the second control, the standby time setting unit 15 may set the standby time Tw to a longer time as the time required for changing the position increases.

[0029] [2. Display and configurable equipment setting process] The procedure for setting the display unit and the settable equipment based on the customization information of the specific user U, which is executed by the mobile object control device 1, will be described with reference to the flowchart shown in FIG.

[0030] 3, when the setting control unit 13 recognizes that the IG switch 60 has been turned ON, the process proceeds to step S2, where the meter 51 and the HUD 52 are displayed in the display mode that was set the last time the vehicle 50 was used. In the following step S3, the user identification unit 11 compares the facial image of the user extracted from the image captured by the in-vehicle camera 80 with the facial image of the specific user recorded in the user data 22, thereby identifying whether the user riding in the vehicle 50 is the specific user U.

[0031] If the user identification unit 11 identifies that the user riding in the vehicle 50 is a specific user U, the process proceeds to step S5, and if the user identification unit 11 identifies that the user riding in the vehicle 50 is not a specific user U, the process proceeds to step S11. In step S5, the customization information acquisition unit 12 refers to the user data 22 to acquire the customization information of the specific user U.

[0032] In the next step S6, the setting control unit 13 starts a second control to change the volume of the alarm sound output from the speaker 74, the set temperature of the air conditioner 90, and the position of the power seat 70 based on the customization information of the specific user U. In the next step S7, the setting control unit 13 displays a notification on the meter 51 that says "Personal settings being reflected" (a display indicating that measures are being taken to set the vehicle to the first setting state and the second setting state).

[0033] In the next step S8, the setting control unit 13 starts a timer with the waiting time Tw as the set time, and when the timer times out in the next step S9, the process proceeds to step S10. In step S10, the setting control unit 13 executes a first control to change the settings of the display modes of the meter 51 and the HUD 52 based on the customization information of the specific user U.

[0034] FIG. 4 is a timing chart when the processing according to the flowchart of FIG. 3 is executed, and shows the timing of the ON / OFF of the IG switch 60, the control of personal settings of the display state of the meter 51 and HUD 52 (first control), and the control of personal settings of the output volume of the alarm sound from the speaker 74, the temperature setting of the air conditioner 90, and the position of the power seat 70 (second control) on a common time axis t.

[0035] At t1, when the IG switch 60 is turned ON, the setting control unit 13 initiates a second control in which the volume of the alarm sound from the speaker 74, the set temperature of the air conditioner 90, and the position of the power seat 70 are adjusted according to the customization information of the specific user U. At this time, the setting control unit 13 displays a notification on the meter 51 saying "Personal settings being reflected."

[0036] At t2, when the waiting time Tw has elapsed since t1, the setting control unit 13 executes the first control to set the display modes of the meter 51 and the HUD 52 to a setting state according to the customization information of the specific user U. In this way, by changing the display modes of the meter 51 and the HUD 52 by the first control after the waiting time Tw has elapsed since the start of the second control, it is possible to prevent the specific user U who views the meter 51 from perceiving flickering.

[0037] 3. Other Embodiments In the above embodiment, the temperature setting of the air conditioner 90 has been described as the second setting, but the temperature setting of the air conditioner 90 may be treated as the first setting by setting the temperature of the air conditioner 90 in conjunction with a setting for whether or not to display the set temperature of the air conditioner 90 on a display such as the meter 51, and a setting for the temperature indicator (number or color indicating the set temperature) to be displayed on the display.

[0038] In the above embodiment, a vehicle 50 is shown as a mobile body of the present disclosure, but the mobile body of the present disclosure may be any mobile body that identifies a user as a specific user and changes the adjustment state of the display unit and configurable equipment according to the settings made by the specific user, and may also be a ship, an aircraft, etc.

[0039] In the above embodiment, the configuration is such that the waiting time is changed by including a waiting time change acceptance unit 14 and a waiting time setting unit 15, but the configuration may also be such that either or both of the waiting time change acceptance unit 14 and the waiting time setting unit 15 are omitted.

[0040] In the above embodiment, the notification "Personal settings being reflected" is displayed on the meter 51 until the waiting time has elapsed, but this display may be omitted. Also, the notification "Personal settings being reflected" may be displayed not only until the waiting time has elapsed, but also until the change in the display mode settings of the meter 51 and the HUD 52 is completed, or until a predetermined time has elapsed since the change in the display mode settings of the meter 51 and the HUD 52 was started.

[0041] In the above embodiment, the electric seat 70, the speaker 74, and the air conditioning unit 90 are given as examples of configurable equipment whose settings by a specific user U are saved, but the setting states of other configurable equipment such as the door mirrors 71, 72, the steering wheel 73, etc. may also be included in the customization information.

[0042] 3, in the above embodiment, when the user identification unit 11 identifies the user who boarded the vehicle 50 as a specific user in step S4, the setting control unit 13 starts the second control in step S6. In another embodiment, the second control may be started when the vehicle 50 transitions to a drivable state by operating the IG switch 60, etc.
