[0009] [First embodiment] Hereinafter, an in-vehicle function control method and an in-vehicle terminal according to the present embodiment will be described with reference to the drawings. In the description of the drawings, the same parts are given the same reference numerals and the description thereof will be omitted.

[0010] [In-vehicle system configuration] The configuration of an in-vehicle system including an in-vehicle terminal according to this embodiment will be described with reference to Fig. 1. Fig. 1 is a block diagram showing the configuration of the in-vehicle system according to this embodiment. As shown in Fig. 1, the in-vehicle system 1 includes an in-vehicle terminal 3 and a plurality of wireless communication devices 5A to 5D.

[0011] The in-vehicle system 1 is a system that provides in-vehicle infotainment (IVI) functions to assist the driver in driving more comfortably. The in-vehicle system 1 wirelessly connects an in-vehicle terminal 3 mounted on the vehicle with portable terminals 7A to 7D used by the vehicle occupants, and controls the functions mounted on the vehicle. Of the portable terminals 7A to 7D, the portable terminal 7A is a portable terminal used by the driver, and the portable terminals 7B to 7D are portable terminals used by the occupants other than the driver.

[0012] The in-vehicle system 1 transmits and receives information using an in-vehicle network while protecting the safety of the vehicle occupants, and provides various in-vehicle functions to the vehicle occupants via the in-vehicle terminal 3. The functions provided by the in-vehicle system 1 include, for example, a navigation function, an air conditioning temperature control function, a speaker volume control function, and also a seat adjustment function that automatically adjusts the seat to suit the occupants.

[0013] The in-vehicle terminal 3 is a terminal for providing IVI functions, and in particular is wirelessly connected to the mobile terminals 7A to 7D used by the vehicle occupants to control the functions installed in the vehicle. The in-vehicle terminal 3 includes a control unit 11 and a storage unit 13, as well as a display device, a touch panel, and the like (not shown).

[0014] The control unit 11 is a controller that executes control for setting functions that can be operated on the mobile terminals 7A to 7D. Specifically, the control unit 11 identifies the mobile terminal 7A used by the driver of the vehicle, and identifies the mobile terminals 7B to 7D used by passengers other than the driver.

[0015] In particular, in this embodiment, wireless communication devices 5A to 5D are arranged in each seat of the vehicle, and the mobile terminal 7A used by the driver is identified and the mobile terminals 7B to 7D used by passengers other than the driver are identified based on the connection status between the wireless communication devices 5A to 5D and the mobile terminals 7A to 7D. Then, the control unit 11 differentiates the functions that can be operated on the mobile terminal 7A used by the driver from the functions that can be operated on the mobile terminals 7B to 7D used by passengers other than the driver.

[0016] The control unit 11 estimates the relative positions of the mobile terminals 7A to 7D with respect to the vehicle by wirelessly communicating with the mobile terminals 7A to 7D via the wireless communication devices 5A to 5D, and performs vehicle control such as locking and unlocking the doors and starting the engine. In particular, the control unit 11 determines whether any of the mobile terminals 7A to 7D is located within a predetermined range from the driver's seat, and identifies the mobile terminal 7A located within the predetermined range from the driver's seat as the mobile terminal used by the driver. Then, the control unit 11 identifies the mobile terminals 7B to 7D other than the identified mobile terminal 7A as mobile terminals used by passengers other than the driver.

[0017] The control unit 11 is configured by a controller having a memory, a processor such as a CPU (Central Processing Unit), and various interfaces. The memory and various interfaces are connected to the processor via a bus. The processor executes programs stored in the memory, and the control unit 11 performs processing to control functions installed in the vehicle.

[0018] The storage unit 13 is a memory or database that stores information necessary for controlling the functions installed in the vehicle by the in-vehicle terminal 3. Specifically, the storage unit 13 stores information recording functions that can be operated on the mobile terminals of the occupants. In addition, if the occupants who use the vehicle are registered users, the storage unit 13 stores user information for each occupant and device information for the mobile terminals owned by each occupant.

[0019] The in-vehicle terminal 3 is a computer configured with general-purpose electronic circuits including a microcomputer, a microprocessor, and a CPU, as well as peripheral devices such as memory, and is installed with a computer program for executing in-vehicle function control processing. Each function of the in-vehicle terminal 3 can be implemented by one or more processing circuits. The processing circuit may include, for example, a programmed processing device including an electrical circuit, and may also include devices such as an application-specific integrated circuit (ASIC) or conventional circuit components arranged to perform the functions described in the embodiments.

[0020] The wireless communication devices 5A to 5D are communication modules for performing wireless communication with the mobile terminals 7A to 7D, and perform, for example, wireless communication of the UWB-IR (Ultra Wide Band-Impulse Radio) system (hereinafter referred to as UWB communication). Each of the wireless communication devices 5A to 5D is configured to be able to perform UWB communication with the other wireless communication devices 5A to 5D installed in the vehicle.

[0021] Each of the wireless communication devices 5A to 5D is connected to the in-vehicle terminal 3 via a dedicated communication line or an in-vehicle network so as to be able to communicate with each other. The operation of each of the wireless communication devices 5A to 5D is controlled by the in-vehicle terminal 3. Note that the wireless communication device 5A is placed so that the driver's seat is its communication area, the wireless communication device 5B is placed so that the passenger seat is its communication area, the wireless communication device 5C is placed so that the right rear seat is its communication area, and the wireless communication device 5D is placed so that the left rear seat is its communication area.

[0022] The mobile terminals 7A to 7D are devices that can access the in-vehicle system 1 via a network, and are, for example, smartphones or tablet terminals that are used daily by the occupants. The mobile terminals 7A to 7D are equipped with communication modules for transmitting and receiving UWB communication impulse signals, and are capable of wireless communication with the wireless communication devices 5A to 5D. Furthermore, the mobile terminals 7A to 7D have installed therein applications required to operate the functions installed in the vehicle via the in-vehicle terminal 3.

[0023] In this embodiment, mobile terminal 7A is a mobile terminal used by the driver, mobile terminal 7B is a mobile terminal used by the passenger in the front passenger seat, mobile terminal 7C is a mobile terminal used by the passenger in the rear seat on the right side, and mobile terminal 7D is a mobile terminal used by the passenger in the rear seat on the left side.

[0024] [In-vehicle function control processing] Next, an in-vehicle function control method using the in-vehicle terminal 3 according to this embodiment will be described. Fig. 2 is a flowchart showing the processing procedure of the in-vehicle function control processing. The in-vehicle function control processing shown in Fig. 2 starts when the power supply of the vehicle is turned on.

[0025] 2, in step S101, the control unit 11 determines whether or not one or more mobile terminals are connected to the in-vehicle terminal 3 via wireless communication. If no mobile terminals are connected, the control unit 11 continues to determine whether or not a mobile terminal is connected, and if one or more mobile terminals are connected, the process proceeds to step S103. For example, in the case of FIG. 1, four mobile terminals 7A to 7D are connected.

[0026] In step S103, control unit 11 determines whether or not any of the portable terminals connected in step S101 is within a predetermined range from the driver's seat. In this embodiment, wireless communication device 5A has the driver's seat as its communication area, so it is sufficient to determine whether or not any portable terminal is connected to wireless communication device 5A. If any portable terminal is within the predetermined range from the driver's seat, the process proceeds to step S105, and if no portable terminal is within the predetermined range from the driver's seat, the process proceeds to step S109.

[0027] In step S105, the control unit 11 determines whether there is only one mobile terminal determined to be within the predetermined range from the driver's seat in step S103. If there is only one mobile terminal within the predetermined range from the driver's seat, the control unit 11 identifies the mobile terminal used by the driver of the vehicle. At the same time, the control unit 11 identifies the mobile terminals used by passengers other than the driver.

[0028] 1, for example, mobile terminal 7A is identified as the mobile terminal used by the driver, and mobile terminals 7B to 7D are identified as the mobile terminals used by passengers other than the driver. If there is only one mobile terminal within a predetermined range from the driver's seat, the process proceeds to step S107, and if there is more than one mobile terminal within the predetermined range from the driver's seat, the process proceeds to step S109.

[0029] In step S107, the control unit 11 sets the functions that can be operated on the mobile terminal to the normal mode. In the normal mode, the control unit 11 differentiates the functions that can be operated on the mobile terminal 7A used by the driver from the functions that can be operated on the mobile terminals 7B to 7D used by passengers other than the driver.

[0030] For example, as shown in Fig. 3, in the navigation function, the mobile terminal 7A used by the driver is set to be able to display only a route guidance screen while the vehicle is traveling, and other functions such as setting a destination cannot be operated. Similarly, the mobile terminal 7A used by the driver is set to be unable to operate functions that are restricted from operation while the vehicle is traveling. In other words, the functions that can be operated on the mobile terminal 7A used by the driver are restricted while the vehicle is traveling.

[0031] In contrast, with the mobile terminals 7B to 7D used by passengers other than the driver, all navigation functions can be operated even while driving, and even functions that are restricted in operation while driving can be operated.

[0032] For example, as shown in Fig. 4, on the route guidance screen of the navigation function, operation icon 41 is displayed on portable terminals 7B to 7D used by passengers other than the driver, but operation icon 41 is not displayed on portable terminal 7A used by the driver while the vehicle is traveling. Therefore, while the vehicle is traveling, the operation to set a destination in the navigation function must be performed from portable terminals 7B to 7D used by passengers other than the driver. In this way, control unit 11 differentiates the functions that can be operated on portable terminal 7A used by the driver from the functions that can be operated on portable terminals 7B to 7D used by passengers other than the driver.

[0033] However, if the destination of the vehicle is set on a mobile terminal 7B to 7D used by a passenger other than the driver, approval of the destination is required on the mobile terminal 7A used by the driver or the in-vehicle terminal 3. Note that all navigation functions can also be operated on the mobile terminal 7A used by the driver while the vehicle is stopped.

[0034] 3, the temperature control of the air conditioning for the entire vehicle and the volume control of the speakers can be controlled by the mobile terminals 7A to 7D used by all the occupants of the vehicle. On the other hand, the temperature control of the air conditioning and the volume control of the speakers provided in each seat of the vehicle can be controlled by the mobile terminal used by the occupant sitting in each seat.

[0035] For example, of the air conditioning temperature adjustment screen shown in Fig. 5, display area 51 is displayed on the driver's mobile device 7A, and display area 52 is displayed on the passenger's mobile device 7B. At this time, when switch button 53 or 54 is pressed, display area 51 or 52 expands to display the entire temperature adjustment screen, allowing temperature adjustment of the entire vehicle. Alternatively, display areas 51 and 52 may be configured to be swapped when switch button 53 or 54 is pressed. When the normal mode is set in this manner, the in-vehicle function control process according to this embodiment ends.

[0036] In step S109, control unit 11 sets the functions that can be operated on the mobile terminal to a restricted mode. Step S109 is a process when there is no mobile terminal at the driver's seat (No in step S103) or when there is more than one mobile terminal at the driver's seat (No in step S105), and therefore is a process when the mobile terminal 7A used by the driver cannot be identified.

[0037] Therefore, in the restricted mode, the functions that can be operated on the mobile terminals 7A to 7D used by all the vehicle occupants are restricted. That is, when the control unit 11 cannot identify the mobile terminal 7A used by the driver, the control unit 11 restricts the functions that can be operated on the mobile terminals 7A to 7D used by all the vehicle occupants.

[0038] For example, in normal mode, the temperature controls of the air conditioning and the volume controls of the speakers installed in each seat of the vehicle can be controlled from the mobile devices of the occupants sitting in each seat, as shown in Figure 3. However, in restricted mode, as shown in Figure 6, the temperature controls of the air conditioning and the volume controls of the speakers installed in each seat are restricted so that they cannot be controlled from the mobile devices of any occupants.

[0039] In addition, the mobile terminals 7B to 7D of the passengers other than the driver are restricted to displaying only the route guidance screen while driving, and are also restricted from operating functions that are restricted while driving. When the restriction mode is set in this way, the in-vehicle function control process according to this embodiment ends.

[0040] [Effects of the first embodiment] As described above in detail, the in-vehicle terminal 3 according to this embodiment identifies the mobile terminal 7A used by the driver of the vehicle and identifies the mobile terminals 7B to 7D used by the passengers other than the driver. The in-vehicle terminal 3 then differentiates the functions that can be operated on the mobile terminal 7A used by the driver from the functions that can be operated on the mobile terminals 7B to 7D used by the passengers other than the driver. This makes it possible to distinguish and set different functions on the driver's mobile terminal and the mobile terminals of the passengers other than the driver. Therefore, it is possible to set functions that should not be operated by the driver so that they cannot be operated on the driver's mobile terminal, thereby improving safety.

[0041] Furthermore, in the in-vehicle terminal 3 according to this embodiment, the temperature adjustment of the air conditioning for the entire vehicle and the volume adjustment of the speakers can be controlled by the mobile terminals used by all occupants of the vehicle. On the other hand, the temperature adjustment of the air conditioning and the volume adjustment of the speakers provided in each seat of the vehicle can be controlled by the mobile terminals used by the occupants sitting in each seat. This allows all occupants to adjust the air conditioning and speaker volume for the entire vehicle, improving convenience. On the other hand, the air conditioning and speaker volume for each seat can be adjusted by the occupants in each seat, so they can be adjusted to suit the preferences of the occupants.

[0042] Furthermore, when the mobile terminal 7A used by the driver cannot be identified, the in-vehicle terminal 3 according to this embodiment restricts the functions that can be operated on the mobile terminals 7A to 7D used by all vehicle occupants. This prevents functions that should not be operated by the driver from being operated on the driver's mobile terminal 7A even when the driver's mobile terminal 7A cannot be identified, thereby improving safety.

[0043] Furthermore, the in-vehicle terminal 3 according to this embodiment limits the functions that can be operated on the mobile terminal 7A used by the driver while the vehicle is traveling. This prevents functions that should not be operated by the driver from being operated on the driver's mobile terminal 7A while the vehicle is traveling, thereby improving safety.

[0044] Furthermore, with the in-vehicle terminal 3 according to this embodiment, if the vehicle's destination is set on a mobile terminal 7B to 7D used by a passenger other than the driver, the destination must be approved on the mobile terminal 7A used by the driver or on the in-vehicle terminal 3. This allows the driver to confirm and approve the destination, preventing the navigation function from guiding the driver to the wrong destination.

[0045] [Second embodiment] Hereinafter, an in-vehicle terminal and an in-vehicle function control method according to this embodiment will be described with reference to the drawings. In the drawings, the same parts are given the same reference numerals and detailed description will be omitted. In the first embodiment, the mobile terminals 7A to 7D were identified by the wireless communication devices 5A to 5D, but in this embodiment, the mobile terminals are identified by photographing the occupants with a camera, which is different.

[0046] [In-vehicle system configuration] The configuration of an in-vehicle system including an in-vehicle terminal according to this embodiment will be described with reference to Fig. 7. Fig. 7 is a block diagram showing the configuration of the in-vehicle system according to this embodiment. As shown in Fig. 7, the in-vehicle system 1 includes an in-vehicle terminal 3 and a camera 71. The in-vehicle system 1 wirelessly connects the in-vehicle terminal 3 installed in the vehicle with mobile terminals 7A to 7D used by the vehicle occupants, and controls functions installed in the vehicle.

[0047] The in-vehicle terminal 3 is a terminal for providing IVI functions, and in particular is wirelessly connected to mobile terminals 7A to 7D used by the vehicle occupants to control the functions installed in the vehicle. The in-vehicle terminal 3 includes a control unit 11, a storage unit 13, and a communication unit 15, as well as a display device, a touch panel, and the like (not shown).

[0048] The control unit 11 is a controller that executes control for setting functions that can be operated on the mobile terminals 7A to 7D. Specifically, the control unit 11 identifies the mobile terminal 7A used by the driver of the vehicle and identifies the mobile terminals 7B to 7D used by the passengers other than the driver, based on an image of the interior of the vehicle captured by the camera 71. The control unit 11 then differentiates the functions that can be operated on the mobile terminal 7A used by the driver from the functions that can be operated on the mobile terminals 7B to 7D used by the passengers other than the driver.

[0049] The control unit 11 registers in advance the user information of the occupants who will use the vehicle. For example, as shown in Fig. 8, the user name, device address, and facial photograph of each occupant are registered in association with each other. The facial photograph is registered by transmitting the photograph to the in-vehicle terminal 3 while the occupant's mobile terminal is connected to the in-vehicle terminal 3.

[0050] The storage unit 13 stores user information of the occupants who use the vehicle, in particular, a facial photograph of each occupant, and also stores device information of the mobile terminals owned by each occupant.

[0051] The communication unit 15 is a communication module having a function of transmitting and receiving information via a network, and performs wireless communication with the mobile terminals 7A to 7D. The communication unit 15 transmits and receives information required to operate the functions installed in the vehicle to and from the mobile terminals 7A to 7D.

[0052] Camera 71 is an imaging unit that captures images of the interior of the vehicle, and is installed at the center of the upper part of the front windshield as shown in Fig. 9, in a position where it can capture images of the faces of all passengers sitting in the vehicle seats. Camera 71 is connected to in-vehicle terminal 3 via communication unit 15, and transmits the captured images to in-vehicle terminal 3. Note that the number of cameras 71 does not need to be one, and multiple cameras may be installed.

[0053] [In-vehicle function control processing] Next, a description will be given of an in-vehicle function control method by the in-vehicle terminal 3 according to this embodiment. Fig. 10 is a flowchart showing the procedure of the in-vehicle function control process.

[0054] As shown in FIG. 10, in step S201, when the engine of the vehicle is started or when an identification request is received from an occupant, the control unit 11 captures an image of the interior of the vehicle cabin with the camera 71 in order to identify the driver.

[0055] In step S203, the control unit 11 compares the image captured in step S201 with the facial photographs registered in the storage unit 13. For example, when an image such as that shown in FIG. 11 is captured by the camera 71, the control unit 11 cuts out an image of an area A1 corresponding to the face of the person sitting in the driver's seat and areas A2 to A4 corresponding to the faces of the people sitting in the other seats, and compares them with the facial photographs of the user information registered in the storage unit 13.

[0056] In step S205, the control unit 11 determines whether or not the face of the person sitting in the driver's seat matches the facial photograph in the user information as a result of the comparison in step S203, and the driver can be identified. If the driver can be identified, the control unit 11 identifies the mobile terminal 7A used by the driver from the device address in the user information, and proceeds to step S207. At this time, the control unit 11 identifies passengers other than the driver from the faces of the people sitting in the other seats, and also identifies the mobile terminals 7B to 7D used by the passengers other than the driver from the device addresses in the user information. On the other hand, if the driver cannot be identified, the process proceeds to step S209.

[0057] Thereafter, in step S207, the control unit 11 sets the functions that can be operated on the mobile terminal to normal mode, and in step S209, sets the functions that can be operated on the mobile terminal to restricted mode. The processes of steps S207 and S209 are the same as the processes of steps S107 and S109 in the first embodiment, and therefore detailed description thereof will be omitted. When the normal mode or restricted mode is set in this way, the in-vehicle function control process according to this embodiment ends.

[0058] [Variations] Vehicle door locks can also be unlocked and the engine started using a virtual key system, which allows users to unlock the doors and start the engine using a virtual key received on their smartphone, while the master key remains with the administrator or owner.

[0059] When using such a virtual key system, the in-vehicle terminal 3 records the device address of the mobile terminal holding the virtual key that started the engine, and identifies the mobile terminal having this device address as the mobile terminal used by the driver. This allows the in-vehicle function control process to be executed in the same manner as in the above-described embodiment.

[0060] [Effects of the second embodiment] As described above in detail, the in-vehicle terminal 3 according to this embodiment identifies the mobile terminal 7A used by the driver of the vehicle and identifies the mobile terminals 7B to 7D used by passengers other than the driver, based on an image of the interior of the vehicle captured by the camera 71. This allows the passengers actually sitting in each seat to be imaged and identified, so that the mobile terminals used by the passengers sitting in each seat can be accurately identified.

[0061] Although the embodiments of the present invention have been described above, the descriptions and drawings that form part of this disclosure should not be understood to limit the present invention. Various alternative embodiments, examples, and operating techniques will become apparent to those skilled in the art from this disclosure. [Explanation of symbols]
