Mode for Carrying Out the Invention

[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 this embodiment, the description of the same or corresponding parts will be omitted or simplified as appropriate.

[0011] Referring to FIG. 1, the configuration of the vehicle 10 according to this embodiment will be described.

[0012] Vehicle 10 is any type of automobile, such as 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. Vehicle 10 may be driven by a user or 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 an abbreviation for Society of Automotive Engineers. Vehicle 10 may also be a vehicle dedicated to MaaS. "MaaS" is an abbreviation for Mobility as a Service.

[0013] Vehicle 10 includes a control device 20 and a user interface 30. The control device 20 can communicate with the user interface 30 and one or more doors 11 such as the back door of the vehicle 10 via a network such as a cable or CAN, or wirelessly. "CAN" is an abbreviation for Controller Area Network. The control device 20 may be able to communicate with a user's portable terminal such as a smart key, a mobile phone, a smartphone, or a tablet via a network such as the Internet. A digital key may be installed in the mobile phone, smartphone, or tablet.

[0014] The control device 20 is a computer mounted on the vehicle 10. The user interface 30 is a touch panel or a switch that provides a GUI. "GUI" is an abbreviation for graphical user interface. The user interface 30 is provided in the vehicle 10 in this embodiment, but may be provided in the user's portable terminal.

[0015] Referring to FIG. 1, the outline of this embodiment will be described.

[0016] When the control device 20 acquires, via the user interface 30, data indicating the door 11 specified by the user and its opening degree, the control device 20 controls the door 11 to open to the specified opening degree. When the specification of the door 11 by the user is received at the user interface 30, the control device 20 sets, as a threshold value, the minimum opening degree at which the door 11 can contact an obstacle existing around the vehicle 10. When the specification of the opening degree of the door 11 by the user is received at the user interface 30, the control device 20 does not accept a specification of an opening degree equal to or greater than the set threshold value, that is, controls the user interface 30 to accept a specification of an opening degree within a range below the threshold value.

[0017] According to the present embodiment, since the specification of the opening degree is accepted only within a range where the obstacle around the vehicle 10 and the door 11 do not come into contact, even when a user at a position where the obstacle cannot necessarily be recognized, such as the driver's seat, performs an operation to open the door 11, the possibility that the door 11 comes into contact with the obstacle is reduced.

[0018] When the specification of the opening degree of the door 11 by the user is received at the user interface 30, as shown in FIG. 2, the control device 20 may display an image 33 of the door 11 and an image 32 of the vehicle body on the screen 31, and control the user interface 30 to change the opening degree of the door 11 on the screen 31 by animation according to a user operation such as a drag operation. The opening degree of the door 11 on the screen 31 is changed only within a range of zero or more and less than the threshold value. The range equal to or greater than the threshold value is displayed as a restricted range 34 so as to be distinguishable from other ranges. For example, the restricted range 34 is displayed in red. Alternatively, when the opening degree of the door 11 on the screen 31 is equal to the threshold value, the control device 20 may control the user interface 30 to notify the user that the door 11 cannot be opened further. For example, the image 33 of the door 11 on the screen 31 may be highlighted in red so that it cannot be opened further.

[0019] Referring to FIG. 1, the configuration of the control device 20 according to the present embodiment will be described.

[0020] The control device 20 includes a control unit 21, a storage unit 22, and a communication unit 23.

[0021] The control unit 21 includes at least one processor, at least one programmable circuit, at least one dedicated circuit, or any combination thereof.

"4G" is an abbreviation for 4th generation. "5G" is an abbreviation for 5th generation. The communication unit 23 receives data used for the operation of the control device 20 and transmits data obtained by the operation of the control device 20.

[0024] The functions of the control device 20 are realized by executing the program according to this embodiment on a processor as the control unit 21. That is, the functions of the control device 20 are realized by software. The program causes a computer to execute the operations of the control device 20, enabling the computer to function as the control device 20. That is, the computer functions as the control device 20 by executing the operations of the control device 20 according to the program.

[0025] The program can be stored in a non-transitory computer-readable medium. The non-transitory computer-readable medium is, for example, a flash memory, a magnetic recording device, an optical disk, a magneto-optical recording medium, or a ROM. The distribution of the program is performed, for example, by selling, transferring, or lending a portable medium such as an SD card, a DVD, or a CD-ROM that stores the program.

For example, data that is not a direct instruction to the computer but has the property of defining the computer's processing corresponds to "things conforming to the program".

[0027] Some or all of the functions of the control device 20 may be realized by a programmable circuit or a dedicated circuit as the control unit 21. That is, some or all of the functions of the control device 20 may be realized by hardware.

[0028] With reference to FIG. 3, the operation of the vehicle 10 according to this embodiment will be described.

[0029] In S1, the vehicle 10 receives a designation of the door 11 of the vehicle 10 via the user interface 30. The control unit 21 of the control device 20 acquires data indicating the door 11 designated by the user from the user interface 30 via the communication unit 23.

[0030] In S2, the control unit 21 of the control device 20 determines whether there is an obstacle around the vehicle 10 using an in-vehicle camera or an in-vehicle sensor. If it is determined that there is no obstacle around the vehicle 10, that is, if no obstacle existing around the vehicle 10 is detected, the step of S3 is executed. On the other hand, if it is determined that there is an obstacle around the vehicle 10, that is, if an obstacle existing around the vehicle 10 is detected, the step of S4 is executed. Alternatively, the step of S4 may be executed only when an obstacle is detected in the vicinity of the door 11 specified in S1 and around the vehicle 10.

[0031] In S3, the vehicle 10 receives a designation of an arbitrary opening degree of the door 11 specified in S1 via the user interface 30. The control unit 21 of the control device 20 acquires data indicating the opening degree designated by the user from the user interface 30 via the communication unit 23. After S3, the step of S6 is executed.

[0032] In S4, the control unit 21 of the control device 20 sets, as a threshold value, the minimum opening degree at which the door 11 specified in S1 can come into contact with the obstacle detected in S2. The control unit 21 of the control device 20 controls the user interface 30 via the communication unit 23 to accept a designation of the opening degree within a range below the set threshold value. After S4, the step of S5 is executed.

[0033] In S5, the vehicle 10 receives, via the user interface 30, a designation of the opening degree of the door 11 designated in S1 within a range below the threshold value set in S4. The control unit 21 of the control device 20 acquires, from the user interface 30 via the communication unit 23, data indicating the opening degree designated by the user. After S5, the step of S6 is executed.

[0034] In S6, the control unit 21 of the control device 20 controls the door 11 designated by the user, indicated by the data acquired in S1, to open to the opening degree designated by the user, indicated by the data acquired in S3 or S5.

[0035] There may be cases where obstacles existing around the vehicle 10 cannot necessarily be accurately recognized from the position of the user, such as the driver's seat. As a modification, even when the user interface 30 is provided on the user's mobile terminal, there may be cases where obstacles existing around the vehicle 10 cannot necessarily be accurately recognized from the position where the user is operating the mobile terminal. However, according to the present embodiment or its modification, even if an operation to open the door is performed via the user interface 30, the door 11 will not accidentally come into contact with an obstacle and be damaged.

[0036] The present disclosure is not limited to the above-described embodiments. For example, two or more blocks described in the block diagram may be integrated, or one block may be divided. Instead of executing two or more steps described in the flowchart in chronological order according to the description, they may be executed in parallel or in a different order according to the processing capabilities of the device that executes each step, or as necessary. In addition, changes can be made without departing from the spirit of the present disclosure.
