  DESCRIPTION OF EMBODIMENTS Hereinafter, preferred embodiments of an in-vehicle electronic device according to the present invention will be described in detail with reference to the accompanying drawings.

  FIG. 1 is a block diagram showing an example of an in-vehicle electronic device according to the present invention. An in-vehicle electronic device 50A shown in the figure functions as an input device for an electronic control unit (ECU) 70 of the car. For this purpose, the in-vehicle electronic device 50A includes an interface unit 10 to which the electronic control unit 70 is connected, a control unit 20A that outputs an operation setting command to the electronic control unit 70 via the interface unit 10, and predetermined image information. Is stored, a display unit 30 whose operation is controlled by the control unit 20A, and an operation unit 35 for inputting a command to the control unit 20A.

  On the other hand, the electronic control unit 70 stores operation setting commands for devices that can be set by the user among devices whose operations are controlled by the electronic control unit 70, such as the room lamp 61, the rheostat 62, the head lamp 63, and the like. It has a rewritable memory (not shown), has a function of controlling the operation of the device according to an operation setting command stored in the rewritable memory, and a function of outputting information on the usage state of the vehicle to the in-vehicle electronic device 50A. is doing.

  The control unit 20A in the in-vehicle electronic device 50A includes a determination unit 11, a display control unit 12A, and a setting output unit 13. The determination unit 11 obtains information on the usage state of the vehicle from the electronic control unit 70, and determines whether or not a predetermined condition is satisfied based on the information. The “predetermined conditions” are, for example, information that triggers the start of operation of a device that can be set by the user, information on the in-vehicle environment, time, road gradient, power-on to the in-vehicle electronic device 50A, etc. Is set. The information that triggers the start of the operation includes the door open / closed state, door lock open / closed state, whether or not the vehicle is parked, whether or not the auto cruise control is used, and the indoor environment information includes the room illuminance. It is.

  The display control unit 12A reads predetermined image information from the storage unit 25A when the determination unit 11 determines that the above condition is satisfied, and indicates that the operation can be set for a predetermined device that can be set by the user. A guide screen is displayed on the display unit 30. In the storage unit 25A, image information corresponding to the guide screen and image information corresponding to an operation setting screen described later are stored for each device that can be set by the user. The display unit 30 is configured using, for example, a liquid crystal display panel or an organic electroluminescence display panel.

  The setting output unit 13 electronically controls the operation setting command corresponding to the operation setting via the interface unit 10 when the user viewing the guide screen calls the operation setting screen and sets the operation from the operation unit 35. Output to unit 70. The operation unit 35 is configured using, for example, a transparent touch panel disposed on the screen of the display unit 30, or a hard switch such as a button switch or an adjustment knob disposed around the display unit 30. The operation setting command output from the setting output unit 13 to the electronic control unit 70 is stored in the rewritable memory of the electronic control unit 70 as described above, and the electronic control unit 70 storing this operation setting command in the rewritable memory is Thereafter, the operation of the device is controlled in accordance with the operation control command.

  FIG. 2 is a flowchart summarizing a procedure performed in the process in which the on-vehicle electronic device 50A described above outputs an operation setting command to the electronic control unit 70. The on-vehicle electronic device 50 </ b> A performs a predetermined step of steps S <b> 1 to S <b> 6 and outputs an operation setting command to the electronic control unit 70.

  In step S1 performed first, as described above, the determination unit 11 determines whether or not a predetermined condition is satisfied. When it is determined that the condition is not satisfied, step S1 is repeated. When it is determined that the condition is satisfied, the process proceeds to step S2, and a guide screen indicating that the operation can be set for a predetermined device that can be set by the user. Is displayed on the display unit 30 by the display control unit 12A.

  In the next step S3, the display control unit 12A determines whether or not a command for instructing the display of the operation setting screen is input from the operation unit 35. When it is determined that the command is not input, step S3 is performed. repeat. On the other hand, when it is determined that the above command has been input, the process proceeds to step S4, the display control unit 12A displays the operation setting screen on the display unit 30, and then the process proceeds to step S5.

  In step S5, the setting output unit 13 determines whether or not an operation setting command has been input from the user according to the operation setting screen. When it is determined in step S5 that the operation setting command has been input, the setting output unit 13 performs step S6 in which the operation setting command is output to the electronic control unit 70, and then proceeds to step S7. The setting output unit 13 determines whether or not it has been input. If it is determined in step S7 that the end command has not been input, the process returns to step S1 to repeat step S1 and subsequent steps. If it is determined that the end command has been input, the operation is terminated.

  On the other hand, when it is determined in step S5 that no operation setting command is input, the process proceeds to step S8, and the setting output unit 13 determines whether an end command is input from the user. If it is determined in step S8 that the end command has not been input, the process returns to step S5 to repeat step S5 and subsequent steps. If it is determined that the end command has been input, the operation ends.

  When the in-vehicle electronic device 50A that operates as described above is used, a guide screen indicating that operation setting is possible for a device that can be set by the electronic control unit 70 is displayed on the display unit 30 when a predetermined condition is satisfied. Therefore, the user can easily grasp the devices that can be set by the user. As a result, it is possible to set an operation according to one's preference even for a device that did not know that user setting is possible.

  Therefore, according to this in-vehicle electronic device 50A, it becomes easy to further enhance the convenience and comfort of the vehicle. In addition, for a device that can be set by a user, a part or all of a switch dedicated to the device can be omitted, so that the available space in the vehicle can be expanded. From this point, it becomes easy to enhance the comfort of the vehicle.

  For example, when a door transitions from a closed state to an open state, from an open state to a closed state, or when a door lock transitions from a closed state to an open state, or from a closed state to an open state, or even indoors When the room lamp 61 (see FIG. 1) is turned on / off under the control of the electronic control unit 70, such as when the illuminance falls below the condition value or in the evening or early morning, it is determined that the above condition is satisfied, The in-vehicle electronic device 50A can be configured such that a guide screen for setting the operation of the room lamp 61 is displayed on the display unit 30 (see FIG. 1).

  Regarding the operation of the room lamp 61, for example, the in-vehicle electronic device 50A is configured so that door interlocking, door lock interlocking, ACC (accessory) power interlocking, time interlocking, illumination interlocking, and the like can be set according to the user's preference. Is done. The door interlock means an operation setting for turning on the room lamp 61 regardless of the open / closed state of the door until a predetermined time has elapsed since the door was opened. In a vehicle having a plurality of room lamps 61, the on-vehicle electronic device 50 </ b> A can be configured so that it can be set which room lamp 61 is turned on according to the position of the opened door.

  The above-described door lock interlock means an operation setting for lighting the room lamp 61 until a predetermined time elapses after the door lock is released or until the door is locked. As in the case of door interlocking, for a vehicle having a plurality of room lamps 61, the in-vehicle electronic device 50A can be set so that which room lamp 61 is lit according to the position of the door whose door lock is released. Can be configured.

  The lighting duration time when the door is interlocked or when the door lock is interlocked can be determined in advance by the electronic control unit 70, or the in-vehicle electronic device 50A can be configured to be set according to the user's preference. . At this time, the in-vehicle electronic device 50A can be configured so that the lighting duration time can be individually set depending on whether the door is opened from the inside of the vehicle. Similarly, when it is possible to determine whether the door lock is released from inside the vehicle or outside the vehicle, the above-mentioned lighting duration time can be set individually when the vehicle is released from inside the vehicle and when it is released from outside the vehicle. The device 50A can also be configured.

  When the ACC power supply is turned on in the state where the door interlock or the door lock interlock is set, the door is closed or the door is locked even during the lighting duration of the room lamp 61. This means an operation setting for turning off the room lamp 61 as long as it is present. Moreover, said time linkage means the operation setting which controls the validity of the above-mentioned door linkage, door lock linkage, or ACC linkage according to the time of the day. For example, the door interlock, door lock interlock, and ACC interlock are disabled during the day, and the room lamp 61 is always turned off. An in-vehicle electronic device 50A is configured. At this time, the electronic control unit 70 detects the time.

  The above illuminance interlock means an operation setting in which the room lamp 61 is not lit even when the door is opened when the in-vehicle illuminance or the out-of-vehicle illuminance is greater than or equal to a predetermined condition value. The The in-vehicle electronic device 50A can be configured so that the above-described condition value can be set only for one of the in-vehicle illuminance and the in-vehicle illuminance, or the in-vehicle electronic device 50A can be configured so that both can be set. The electronic control unit 70 detects the illuminance inside the vehicle and the illuminance outside the vehicle.

  It may be preferable to turn on the room lamp for a relatively long time, such as when searching in a car at night. For example, a hard switch is provided in the room lamp, and the hard switch is turned on and off. The validity / invalidity of the above-described operation setting may be controlled. When the above-described operation setting is invalid, the room lamp continues to be lit.

  In addition, for the rheostat 62 (see FIG. 1), when the meter illuminance shifts from the non-dimming state to the dimming state or from the dimming state to the non-dimming state under the control of the electronic control unit 70. Alternatively, it is determined that the above-mentioned condition is satisfied when the vehicle shifts from the running state to the parking state, and the in-vehicle electronic device 50A is set so that a guide screen about the operation setting of the rheostat 62 is displayed on the display unit 30. Can be configured.

  About operation | movement of the rheostat 62 (refer FIG. 1), 50A of vehicle-mounted electronic devices are comprised so that parking interlocking | linkage, illumination intensity interlocking, etc. can be set according to a user preference, for example. The parking interlock means an operation setting for increasing the meter illuminance adjusted by the rheostat 62 during parking. The electronic control unit 70 determines whether the vehicle is parked or stopped.

  The illuminance interlock means an operation setting for changing the meter illuminance adjusted by the rheostat 62 according to the in-vehicle illuminance or the presence / absence of lighting of the headlamp. For example, the vehicle-mounted electronic device 50A can be set so that the user can individually set the illuminance according to his / her preference for the meter illuminance when the in-vehicle illuminance is high such as daytime and for the meter illuminance when the in-vehicle illuminance is low such as nighttime. Is configured. Further, the in-vehicle electronic device 50A is configured so that the illuminance can be set separately when the headlamp 63 (see FIG. 1) is turned off and when it is turned on. The electronic control unit 70 detects the in-vehicle illuminance and the presence / absence of lighting of the headlamp 63.

  As for the headlamp 63 (see FIG. 2), when the light projection angle at the time of lighting changes according to the road slope condition, that is, depending on whether traveling on a flat ground, uphill, or downhill, The in-vehicle electronic device 50 </ b> A can be configured such that a guide screen about the operation setting is displayed on the display unit 30 when the light projection angle changes. The electronic control unit 70 detects whether the vehicle is traveling on a flat ground, uphill, or downhill.

  The in-vehicle electronic device 50A can be configured such that the guide screen is displayed every time the above-described conditions are satisfied, or after the number of operation settings for the same device reaches a predetermined upper limit value. The in-vehicle electronic device 50A can be configured so that the guide screen is not displayed even if the above-described conditions are satisfied. For example, the in-vehicle electronic device is configured so that the operation setting command input from the operation unit 35 (see FIG. 1) is output to the electronic control unit 70 by the setting output unit 13 and also output to the storage unit 25A and stored as the operation setting history. If the device 50A is configured, the control unit 20A can detect the number of operation settings for the same device based on the operation setting history stored in the storage unit 25A. After reaching the predetermined upper limit value, it is possible to prevent the guide screen from being displayed even if the above-described condition is satisfied.

  In the in-vehicle electronic device of the present invention, a device that can be set by the electronic control unit can be configured such that a plurality of users can perform operation settings of the device according to their preferences.

  FIG. 3 is a block diagram schematically illustrating an example of an in-vehicle electronic device that allows a plurality of users to perform device operation settings according to their preferences. The in-vehicle electronic device 50B shown in the figure has the same configuration as the in-vehicle electronic device 50A shown in FIG. 1 except that it includes a control unit 20B having a user confirmation unit 14. Among the constituent elements shown in FIG. 3, those common to the constituent elements shown in FIG. 1 are given the same reference numerals as those used in FIG. 1 and description thereof is omitted.

  The user confirmation unit 14 obtains user identification information from the electronic control unit when, for example, the car electronic control unit performs key authentication. Alternatively, the operation of the display control unit 12 </ b> A is controlled to display a user confirmation screen on the display unit 30, and the user is confirmed by a command input from the operation unit 35. For the first confirmed user, the identification information of the user is registered in the storage unit 25A.

  When the user is confirmed by the user confirmation unit 14, the determination unit 11 is a trigger that causes the display unit 30 to display a guide screen indicating that the operation can be set for the above-described conditions, that is, user-configurable devices, for each user. It is determined whether or not the following condition is satisfied. If the operation setting history is stored for each user in the storage unit 25A, it can be easily determined from the operation setting history whether or not the above condition is satisfied for each user.

  When it is determined that the above condition is satisfied for the first time for the current user, the display control unit 12A causes the display unit 30 to display the above-described guide screen. The above conditions include users. For example, the in-vehicle electronic device 50B can be configured such that a guide screen for the operation setting of the device that adjusts the angle of the door mirror is displayed after the user confirmation for the user who is confirmed for the first time.

  Further, the display control unit 12 </ b> A displays the operation setting screen on the display unit 30 when a command for displaying the operation setting screen is input from the operation unit 35. When the operation setting command is input from the operation unit 35, the setting output unit 13 outputs the operation setting command to the electronic control unit 70 via the interface unit 10, while the operation setting history is displayed for each user. Store in the storage unit 25A.

  In the in-vehicle electronic device 50B configured as described above, a plurality of users can perform operation settings of the above devices according to individual preferences. Therefore, the convenience and comfort of the vehicle can be improved compared to the in-vehicle electronic device 50A. Becomes easier.

  In the in-vehicle electronic device of the present invention, when the vehicle is running when displaying the guide screen, only the icon of the guide screen is displayed on the display unit, and when the vehicle is not running, the user can display the guide screen from the above icons. It can also be configured to be called.

  The configuration of the in-vehicle electronic device in this case has a function of determining whether or not the vehicle is traveling by acquiring information on the traveling state of the vehicle from the electronic control unit, and when it is determined that the vehicle is traveling A configuration similar to the on-vehicle electronic devices 50A and 50B described in the first and second embodiments may be used except that the display control unit is added with a function of creating an icon of the guide screen and displaying the icon on the display unit. Since it is possible, the illustration is omitted here.

  FIG. 4 is a flowchart illustrating an example of a procedure performed in a process in which an in-vehicle electronic device having a function of converting a guide screen into an icon during driving of the vehicle outputs an operation setting command to the electronic control unit. In the illustrated example, steps S1a to S1d are added to the procedure shown in FIG. Of the steps shown in FIG. 4, those common to the steps shown in FIG. 2 are denoted by the same reference numerals as those used in FIG. 2, and description thereof is omitted.

  Step S1a described above is a step performed subsequent to step S1 described with reference to FIG. 2, and in this step S1a, the display control unit acquires information on the traveling state of the vehicle from the electronic control unit, and the vehicle travels. Determine if it is in the middle. If it is determined in step S1a that the vehicle is not traveling, the process proceeds to step S2 where the display control unit displays a guide screen on the display unit, and thereafter, step S3 and subsequent steps described with reference to FIG. 2 are performed.

  On the other hand, when it is determined that the vehicle is traveling in step S1a, the process proceeds to step S1b, and the display control unit converts the guide screen into an icon and displays it on the display unit. Thereafter, step S1c is performed in which the display control unit determines whether or not the user has called the guide screen from the icon. When it is determined that the guide screen has been called, the process proceeds to step S2 to perform step S2 and subsequent steps. When it is determined that the guide screen is not called, the process proceeds to step S1d, and the display control unit determines whether or not an end command is input from the user. When it is determined in step S1d that the end command is not input, the process returns to step S1c, and when it is determined that the end command is input, the operation is ended.

  In addition, it is preferable to avoid that the driver inputs the operation setting command while driving the vehicle from the viewpoint of safe driving. On the other hand, it is effective for improving convenience for the passenger, not the driver, to input the operation setting command while the vehicle is traveling. In step S1c described above, when it is determined that the user has called the guide screen from the icon while the vehicle is traveling, the on-vehicle electronic device is configured such that the operation setting screen is displayed on the display unit even after the vehicle is traveling. Whether or not the apparatus is configured can be selected as appropriate.

  The in-vehicle electronic device configured as described above has the same technical effect as the in-vehicle electronic device 50A (see FIG. 1) described in the first embodiment. In addition, the guide screen is iconified while the vehicle is running, and the driver's intention to input the operation setting command while driving the vehicle is suppressed, so that a reduction in safety can be suppressed.

  In the in-vehicle electronic device according to the present invention, when a device that can be set by a user among devices controlled by the electronic control unit operates differently from the normal operation setting screen of the device is automatically displayed. Functions can also be added.

  FIG. 5 is a block diagram schematically illustrating an example of an in-vehicle electronic device configured to automatically display an operation setting screen of a device when the device performs an operation different from a normal operation. The in-vehicle electronic device 50C shown in the figure includes a control unit 20C having an operation comparison unit 15, and a standard operation for a device that can be set by a user among devices that the electronic control unit 70 controls the operation. Except for the point that the model includes a storage unit 25B stored in advance, it has the same configuration as the in-vehicle electronic device 50A shown in FIG. Among the constituent elements shown in FIG. 5, those common to the constituent elements shown in FIG. 1 are given the same reference numerals as those used in FIG. 1 and description thereof is omitted.

  The operation comparison unit 15 always obtains information on the operation status of the device from the electronic control unit 70, compares it with the standard operation model in the storage unit 25B, and performs display control when there is a device that operates differently from the standard model. The operation of the unit 12A is controlled to display on the display unit 30 a guide screen indicating that the operation can be set for the device. That is, when the operation is different from that of the standard operation model, the “predetermined condition” described in the first embodiment is established.

  For example, when the headlamp 63 is turned on and not turned on for the operation of the rheostat 62, a standard operation model is created and stored in the storage unit 25B. When the operation of the rheostat 62 is set by the user so as to be equal to or greater than the condition value, a guide screen for prompting resetting can be displayed on the display unit 30.

  When the user displays an operation setting screen based on this guide screen and inputs an operation setting command from the operation unit 35, the setting output unit 13 outputs the operation setting command to the electronic control unit 70 via the interface unit 10. The electronic control unit 70 that has received this operation setting command thereafter controls the operation of the device according to the content of the operation control command.

  The on-vehicle electronic device 50C configured as described above has the same technical effect as the on-vehicle electronic device 50A (see FIG. 1) described in the first embodiment. Furthermore, since the guide screen indicating that the operation can be set when the device operates differently from the standard model is automatically displayed on the display unit 30, there is an error in the content of the operation setting performed by the user. Sometimes it can be urged to reset. Therefore, according to the in-vehicle electronic device 50C, it becomes easier to enhance the convenience and comfort of the vehicle.

  The in-vehicle electronic device according to the present invention can be added with a function as an audio visual device such as a television receiver, a music sound reproducing device, and a car navigation device.

  FIG. 6 is a block diagram illustrating an example of an in-vehicle electronic device to which a function as an audio visual device is added. The on-vehicle electronic device 50D shown in the figure is the same as the on-vehicle electronic device 50A shown in FIG. 1 except that the on-vehicle electronic device 50D includes a second interface unit 19, a control unit 20D, a speaker unit 40, and an information reading unit 45. It has a configuration. 6 that are the same as those shown in FIG. 1 are assigned the same reference numerals as those used in FIG. 1 and description thereof is omitted. Since the first interface unit in FIG. 6 has the same function as the interface unit 10 shown in FIG. 1, the first interface unit is denoted by reference numeral “10”.

  The second interface unit 19 receives a television broadcast radio wave or a signal from a GPS (Global Positioning System) and sends a predetermined electrical signal to the control unit 20D. The control unit 20D includes an audio visual (AV) control unit 12B and a communication control unit 16 in addition to the determination unit 11 and the setting output unit 13 already described with reference to FIG. The audio visual control unit 12B displays the operation setting screen on the display unit 30 in the same manner as the display control unit 12A already described with reference to FIG. 1, and in addition to the second interface unit under the control of the communication control unit 16. 19, the operation of the display unit 30 is controlled based on the electrical signal sent from the information reading unit 45, and a predetermined image is displayed on the display unit 30. Further, the operation of the speaker unit 40 is controlled based on the electrical signal sent from the second interface unit 20 or the information reading unit 45, and the speaker unit 40 is made to reproduce a predetermined musical sound.

  The speaker unit 40 reproduces musical sounds, and the information reading unit 45 reads video information and musical tone information recorded on a removable medium such as a CD-ROM or DVD, converts them into electrical signals, and transmits them to the audio visual control unit 12B. .

  In the in-vehicle electronic device 50D configured as described above, the second interface unit 19 and the information reading unit 45 are an information acquisition unit that acquires image information and musical tone information from a removable medium or an external device, or an external device (GPS system). Since it functions as an information acquisition unit that acquires vehicle position information from the vehicle, it also functions as an audiovisual device such as a television receiver, a music player, or a car navigation device. Of course, the same technical effects as those of the in-vehicle electronic device 50A described in the first embodiment are also obtained. Therefore, according to the in-vehicle electronic device 50D, it is even easier to enhance the convenience and comfort of the vehicle than the in-vehicle electronic device 50A (see FIG. 1) described in the first embodiment.

  In order to make the in-vehicle electronic device 50D function as a car navigation device, for example, a function of receiving a signal representing vehicle position information from the GPS system system is given to the second interface unit 19, and the information reading unit 45 includes Removable media on which map information is recorded is loaded. The audio visual control unit 12B causes the display unit 30 to display the vehicle position information superimposed on the map information read from the removable medium by the information reading unit 45.

  By the way, in the first to fifth embodiments, for example, information that triggers the start of operation of a device that can be set by the user, information on the in-vehicle environment, time, road gradient, power on the in-vehicle electronic device 50A, and the like are used. The example in which the user is notified of the operation setting screen when the set “predetermined condition” is satisfied has been described, but the present invention is not limited to this.

  The in-vehicle electronic device disclosed in the present application can notify the user of the operation setting screen even when, for example, a user operation condition is satisfied or an environment change condition is satisfied. In other words, the in-vehicle electronic device disclosed in this application prompts the user to adjust the operation setting at the timing when a user operation such as turning on the headlight occurs or when the scene that requires a room lamp or rheostat is reached. it can. In this way, the in-vehicle electronic device side not only notifies the user of the operation setting screen, but also allows the user to adjust settings according to the situation, and provides an HMI (Human Machine Interface) function that is user-friendly. be able to.

  Accordingly, in the sixth embodiment, an example in which the user is prompted to adjust the operation setting at the timing when the user operation occurs or the timing when the room lamp or the rheostat is required will be described with reference to FIGS.

  First, the configuration of the in-vehicle electronic device according to the sixth embodiment will be described with reference to FIG. FIG. 7 is a block diagram illustrating the configuration of the in-vehicle electronic device according to the sixth embodiment.

  As illustrated in FIG. 7, the in-vehicle electronic device 500A according to the sixth embodiment includes an interface unit 100, a control unit 200A, a storage unit 250, a display unit 300, and an operation unit 350, and includes an ECU 700. Are connected to the room lamp 610, the rheostat 620, the headlamp 630, the illuminance sensor 640, the shift lever 650, and the parking brake 660, respectively.

  The peripheral device connected to the in-vehicle electronic device 500A will be described first. The room lamp 610 is a light that illuminates the inside of the vehicle based on the user's ON / OFF operation, and the rheostat 620 is a resistance by turning a knob. A switch whose value changes, for example, a switch for meter illumination or the like. The headlamp 630 is a light that irradiates the front of the vehicle with a switch provided in the vehicle.

  The illuminance sensor 640 is a sensor that detects the brightness inside the vehicle provided inside the vehicle or a sensor that detects the brightness outside the vehicle provided outside the vehicle. The shift lever 650 is a sensor that detects the brightness outside the vehicle. The parking brake 660 is a sensor that detects ON / OFF of the parking brake of the vehicle.

  The ECU 700 is an electronic unit having the same function as the ECU 70 described in the first embodiment. In the sixth embodiment, the illuminance in the vehicle detected by the illuminance sensor 640, the position of the shift lever acquired from the shift lever 650, ON / OFF of the parking brake acquired from the parking brake 660 is output to the in-vehicle electronic device 500A.

  Returning to the configuration of the in-vehicle electronic device 500A, the interface unit 100 is an interface for controlling communication related to various information exchanged with the ECU 700. For example, the illuminance in the vehicle, the position of the shift lever, ON / OFF of the parking brake Etc. are acquired from ECU700. In addition, the interface unit 100 transmits the operation setting contents such as the switch output from the in-vehicle electronic device 500A, the change contents, and the like via the ECU 700, the loop lamp 610, the rheostat 620, the head lamp 630, the illuminance sensor 640, and the shift lever 650. And output to the parking brake 660.

  The display unit 300 includes a monitor (or a display) and a speaker, and displays and outputs an operation setting screen output from the control unit 200A, for example. The operation unit 350 is an input unit that realizes a pointing device function in cooperation with the keyboard, mouse, microphone, and display unit 300. For example, an operation setting change request from a user or an operation setting screen A command or the like for instructing display is received and output to control unit 200A. Further, the display unit 300 and the operation unit 350 do not need to be realized separately as shown in the figure. For example, the display unit 300 and the operation unit 350 are realized as the same processing unit like a touch panel. Also good. This is not limited to the sixth embodiment, and the same applies to other embodiments.

  The storage unit 250 stores data and programs necessary for various processes by the control unit 200A, and stores image information such as an operation setting screen output to the display unit 300 by the control unit 200A, for example.

  The control unit 200A has an internal memory for storing a control program such as an OS (Operating System), a program defining various processing procedures, and required data, and a determination unit 110, a display control unit 120A, and a setting output. Unit 130 and executes various processes. The determination unit 110, the display control unit 120A, and the setting output unit 130 have the same functions as the determination unit 11, the display control unit 12A, and the setting output unit 13 described in the first embodiment. Only functions different from Example 1 will be described.

  The determination unit 110 determines whether or not the operation unit 350 has detected a user operation, or whether or not there has been an environmental change that recommends changing the switch operation setting based on information acquired from the ECU 700. Specifically, the determination unit 110 instructs the display control unit 120A to display a screen when a user operation occurs or when the environment changes. By doing so, the user can adjust the setting according to the situation at that time, and can provide an HMI function that is easy for the user operation.

  For example, when the determination unit 110 detects that the room light 610 is turned on, the rheostat 620 is turned on, or the headlight 630 is turned on via the ECU 700, The display control unit 120A is instructed to display a screen. That is, the determination unit 110 displays an operation setting screen when a user operates a switch that allows operation settings such as illuminance, irradiation range, and timing.

  In addition, the determination unit 110 causes the display control unit 120A to detect when the illuminance (brightness) detected by the illuminance sensor 640 and acquired through the ECU 700 has changed by a predetermined threshold or more than the previously detected value. Instructs screen display. For example, the determination unit 110 displays the display control unit 120A when the illuminance (brightness) acquired at a predetermined interval (for example, once every 10 minutes) is higher or lower than the previously acquired illuminance by 10 lux or more. To display the screen.

  Further, when an operation such as a command input indicating a switch operation setting change request or an operation screen pressing is received by the operation unit 350, the determination unit 110 instructs the display control unit 120A described later to display a screen. Further, since an operation change during driving may hinder safe driving, for example, the operation setting change request described above is accepted by the operation unit 350 and the position of the shift lever received from the ECU 700 is “P” ( Alternatively, when the parking brake received from the ECU 700 is “ON”, the display control unit 120A described later may be instructed to display a screen.

  That is, the determination unit 110 can instruct the display control unit 120A to display a screen only when the operation setting change request is received by the operation unit 350 and the vehicle is stopped. In addition, although the example which used the shift lever 650 and the parking brake 660 was demonstrated as a method of determining that the vehicle stopped here, you may use a speed sensor (vehicle speed sensor) etc. besides this.

  When the display control unit 120A receives an instruction to output the operation setting change screen from the determination unit 110, the display control unit 120A reads the operation setting change screen from the storage unit 250 and causes the display unit 300 to display the operation setting change screen. In addition, when receiving an instruction to output an operation setting change screen from the determination unit 110, the display control unit 120A stores a guide screen indicating that operation setting can be performed for a predetermined device that can be set by the user. The operation setting change screen is read from the storage unit 250 when the operation such as the operation setting start is performed or a predetermined time elapses, and then the display unit 300 reads the operation setting change screen. Can also be displayed.

  The setting output unit 130 outputs an operation setting command corresponding to the operation setting to the ECU 700 via the interface unit 100 when the user who viewed the guide screen calls the operation setting screen and sets the operation from the operation unit 350. Specifically, when the setting change is made on the operation setting screen displayed on the display unit 300 so that the meter illumination is brightened, the setting output unit 130 is set to the newly set illuminance. The rheostat 620 is set and controlled via the ECU 700.

  Next, the flow of processing when a user operation is detected in the in-vehicle electronic device according to the sixth embodiment will be described with reference to FIGS. 8 and 9. FIG. 8 is a flowchart illustrating a process flow (with a guide screen) when detecting a user operation in the in-vehicle electronic device according to the sixth embodiment. FIG. 9 is a flowchart illustrating a process during user operation detection in the in-vehicle electronic device according to the sixth embodiment. It is a flowchart which shows the flow of a process (no guide screen).

  As illustrated in FIG. 8, when the in-vehicle electronic device 500A detects a user operation (Yes in step S101), the on-vehicle electronic device 500A indicates that operation setting can be performed for a device that can be set by the user among devices whose operation is controlled by the ECU 700. The guide screen is displayed and output on the display unit 300 (step S102).

  For example, when the user detects that the power source of the headlamp 630 and the room lamp 610 is turned on, the in-vehicle electronic device 500A detects the headlamp 630 and the room lamp 610 that are turned on. A guide screen indicating that the operation setting is possible for a device (for example, a rheostat 620, an air conditioner, a speaker output setting, etc.) that can be set by the user is displayed on the display unit 300.

  When the command for instructing the display of the operation setting screen is received by the operation unit 350 or the like (Yes at Step S103), the in-vehicle electronic device 500A displays and outputs the operation setting screen on the display unit 300 (Step S104).

  As a specific example, the in-vehicle electronic device 500 </ b> A is configured such that a button indicating a transition to an operation setting screen such as “operation setting” displayed on the guide screen is pressed or “operation” is performed by voice recognition of a user-generated word. When the “setting” is recognized or a predetermined time has elapsed since the guide screen was displayed, the operation setting screen is displayed on the display unit 300.

  Thereafter, when the in-vehicle electronic device 500A detects that the setting input is made by the user on the operation setting screen displayed on the display unit 300 (Yes in step S105), the in-vehicle electronic device 500A sets the setting contents to the corresponding device or sensor via the EUC 700. To reflect the setting contents (step S106).

  As a specific example, the in-vehicle electronic device 500 </ b> A displays the brightness of the headlight 630 when the user inputs a setting for increasing the brightness of the headlamp 630 on the operation setting screen displayed on the display unit 300. The contents set in the adjustment device etc. are output to reflect the set contents.

  When the in-vehicle electronic device 500A detects an instruction to end the operation setting (Yes at Step S107), the in-vehicle electronic device 500A ends the process and does not detect an instruction to end the operation setting (No at Step S107), Step S101. Return to and repeat the subsequent processing.

  To give a specific example, the in-vehicle electronic device 500A terminates the processing when a button such as “End” displayed on the operation setting screen is pressed, and displays “End” displayed on the operation setting screen. When a predetermined time elapses without the button being pressed, or when a button indicating transition to another operation setting such as “setting change” or “next setting” is pressed, the process returns to step S101 and the subsequent processing repeat.

  On the other hand, when the in-vehicle electronic device 500A detects an instruction to end the setting on the operation setting screen displayed on the display unit 300 without detecting the setting input by the user (No at Step S105). (Yes in step S108) When the process is terminated and an instruction to end the setting is not detected (No in step S108), the process returns to step S105 to execute the subsequent processes.

  To give a specific example, the in-vehicle electronic device 500A terminates the processing when a button such as “End” displayed on the operation setting screen is pressed, and displays “End” displayed on the operation setting screen. If a predetermined time elapses without the button being pressed, or if a button indicating a transition to another operation setting such as “setting change” or “next setting” is pressed, the process returns to step S105 to perform the subsequent processing. Execute.

  Moreover, although the example which displays a guide screen was demonstrated in FIG. 8, this guide screen does not necessarily need to be output. Therefore, a processing flow (without a guide screen) when detecting a user operation will be described with reference to FIG.

  As illustrated in FIG. 9, when the in-vehicle electronic device 500A detects a user operation (Yes in Step S201), the in-vehicle electronic device 500A inquires the user whether to display the operation setting screen without displaying the guide screen (Step S202).

  To give a specific example, for example, when the user detects that the power source of the headlamp 630, the room lamp 610, and the like is turned on, the in-vehicle electronic device 500A performs operation setting of the device that is turned on. An inquiry screen for inquiring whether or not to display the operation setting screen on the display unit 300 is output.

  Subsequently, when the in-vehicle electronic device 500A is instructed by the user to display the operation setting screen (Yes in step S202), the in-vehicle electronic device 500A displays and outputs the operation setting screen on the display unit 300 (step S203).

  For example, the in-vehicle electronic device 500A displays the operation setting screen when a button indicating a transition to an operation setting screen such as an “operation setting screen” displayed on the displayed inquiry screen is pressed. A display is output on the display unit 300. Note that the operation setting screen may be displayed immediately when a user operation is detected in step S201 without making an inquiry in step S202.

  The subsequent processing from step S204 to step S207 is the same as the processing from step S105 to step S108 described in FIG.

  8 and FIG. 9, although the example triggered by the user operation has been described, other than this, for example, the same processing can be executed also triggered by the environmental change. Therefore, an example in which the operation setting screen is notified to the user when the environment changes is described next with reference to FIGS. 10 and 11.

  FIG. 10 is a flowchart illustrating a flow of processing (with a guide screen) when an environmental change is detected in the in-vehicle electronic device according to the sixth embodiment. As illustrated in FIG. 10, when the in-vehicle electronic device 500 </ b> A detects an environmental change (Yes in step S <b> 301), the on-vehicle electronic device 500 </ b> A indicates that operation setting can be performed for a device that can be set by the user among devices whose operation is controlled by the ECU 700. The guide screen is displayed and output on the display unit 300 (step S302).

  To give a specific example, the in-vehicle electronic device 500A is, for example, when the illuminance (brightness) detected by the illuminance sensor 640 changes by a predetermined threshold or more than the previously detected value. When an environmental change such as the driving environment or the ride comfort of the occupant is detected, a guide screen is displayed on the display unit 300.

  Since the subsequent processing of step S303 to step S308 is the same as the processing of step S103 to step S108 described in FIG. 8, detailed description thereof is omitted here.

  Also, in the example in which the user is notified of the operation setting screen when the environmental change described above is detected, the guide screen does not necessarily need to be output, as in the case where the user operation is detected and the operation setting screen is notified. Therefore, next, a processing flow (without a guide screen) when detecting an environmental change will be described with reference to FIG. FIG. 11 is a flowchart illustrating a process flow (without a guide screen) when an environmental change is detected in the in-vehicle electronic device according to the sixth embodiment.

  As illustrated in FIG. 11, when the in-vehicle electronic device 500 </ b> A detects an environmental change (Yes in Step S <b> 401), the in-vehicle electronic device 500 </ b> A inquires the user whether to display the operation setting screen without displaying the guide screen (Step S <b> 402).

  As a specific example, the in-vehicle electronic device 500 </ b> A is detected by the illuminance sensor 640 when the illuminance (brightness) detected by the illuminance sensor 640 has changed by a predetermined threshold or more than the previously detected value. When it is detected that the brightness outside the vehicle is dark, an inquiry screen for inquiring whether or not to display the operation setting screen on the display unit 300 is output.

  Note that the subsequent processing of step S403 to step S407 is the same as the processing of step S203 to step S207 described with reference to FIG.

  Thus, in the in-vehicle electronic device according to the sixth embodiment, for example, even when the user operation condition is satisfied or the environment change condition is satisfied, the operation setting screen can be notified to the user. In other words, the in-vehicle electronic device disclosed in this application prompts the user to adjust the operation setting at the timing when a user operation such as turning on the headlight occurs or when the scene that requires a room lamp or rheostat is reached. it can. By doing so, the in-vehicle electronic device side does not simply notify the user of the operation setting screen, but the user can adjust the setting according to the situation, and can provide an HMI function that is easy for the user operation.

  Next, referring to FIG. 12, when the vehicle is running when displaying the guide screen, only the icon of the guide screen is displayed on the display unit, and when the vehicle is not running, the user can change the guide screen from the above icons. An example of configuring so that can be called will be described.

  FIG. 12 is a flowchart illustrating the flow of processing in the in-vehicle electronic device according to the seventh embodiment. As shown in FIG. 12, the in-vehicle electronic device 500A converts the guide screen into an icon and displays it on the display unit 300 when at least one condition of user operation or environment change described in FIGS. 8 to 11 is established (Yes in step S501). The display is output (step S502).

  Subsequently, the in-vehicle electronic device 500A that displays the guide screen as an icon displays the position of the shift lever acquired from the shift lever 650 via the ECU 700, ON / OFF of the parking brake acquired from the parking brake 660 via the ECU 700, or Then, based on the vehicle speed acquired from a vehicle speed sensor (not shown) or the like, it is determined whether or not the vehicle is traveling (step S503).

  In the in-vehicle electronic device 500A, for example, the position of the shift lever is “D” or “R” other than “P”, the parking brake is OFF, or the vehicle speed is other than “0”. When it is determined that the vehicle is traveling (Yes in step S503), for example, an icon operation impossible message such as “cannot operate an icon while traveling” is displayed on the display unit 300, or voice is output from a speaker (not shown). Then, the backlight of the display unit 300 is turned off to notify the user that the icon cannot be operated (step S504).

  On the other hand, the in-vehicle electronic device 500A determines that the vehicle is stopped, for example, because the position of the shift lever is “P”, the parking brake is ON, or the vehicle speed is “0”. In the case (No in Step S503), or when it is determined that the vehicle has stopped (No in Step S505) while the icon operation is impossible (Step S504), for example, an icon operable message such as “I can operate the icon” is displayed on the display unit. The information is displayed on the screen 300, the sound is output from a speaker (not shown), or the backlight of the display unit 300 is turned on to notify the user that the icon can be operated (step S506). In addition, after performing step S504, when it cannot be determined that the vehicle has stopped (No in step S505), the processing in step S504 is repeated.

  Thereafter, for example, when the icon is clicked to detect a screen call (Yes in step S507), the in-vehicle electronic device 500A inquires whether or not to display an operation setting screen for performing operation settings on the display unit 300. (Step S508).

  The subsequent processing of step S508 to step S512 is the same as that of step S303 to step S308 described with reference to FIG. 10. When a command for instructing display of the operation setting screen is received by the operation unit 350 or the like, the operation setting screen is output. When the setting is changed on the screen, the setting is reflected on the corresponding device.

  On the other hand, the in-vehicle electronic device 500A, for example, when a predetermined time elapses or the “end” button on the icon is pressed without detecting a screen call such as when the icon is clicked (No in step S507). A screen for inquiring whether to end the operation setting is output (step S513).

  Then, for example, when it is detected that the operation setting is ended by pressing the “end” button (Yes in step S513), the in-vehicle electronic device 500A ends the process and ends the operation setting. If not detected (No at step S513), the process returns to step S503 to execute the subsequent processing.

  By the way, in the sixth and seventh embodiments, the in-vehicle electronic device having the configuration described in FIG. 1 is described as an example. However, even in the in-vehicle electronic device having the configuration disclosed in FIG. 3, FIG. 5, and FIG. A similar process can be executed.

  Therefore, in the eighth embodiment, another configuration capable of realizing the functions of the sixth and seventh embodiments will be described with reference to FIGS.

  First, the configuration of the in-vehicle electronic device when a plurality of users perform operation settings of the device according to their preferences will be described with reference to FIG. FIG. 13 is a block diagram illustrating a configuration of an in-vehicle electronic device when a plurality of users perform operation settings of the device according to their preferences.

  As illustrated in FIG. 13, the in-vehicle electronic device 500B includes an interface unit 100, a control unit 200B, a storage unit 250A, a display unit 300, and an operation unit 350. The lamp 610, the rheostat 620, the headlamp 630, the illuminance sensor 640, the shift lever 650, and the parking brake 660 are connected to each other.

  Among them, the interface unit 100, the display unit 300, the operation unit 350, the ECU 700, the room lamp 610, the rheostat 620, the headlamp 630, the illuminance sensor 640, the shift lever 650, and the parking brake 660. 7 has the same function as that described with reference to FIG. 7, and therefore description thereof is omitted. Here, the control unit 200B and the storage unit 250A having functions different from those in FIG. 7 will be described.

  The storage unit 250A stores data and programs necessary for various processes performed by the control unit 200B. For example, user identification information used for user confirmation by the control unit 200B, a history of operation settings changed by the user in the past, and the like. Remember.

  The control unit 200B includes an internal memory for storing a control program such as an OS (Operating System), a program defining various processing procedures, and necessary data, and a determination unit 110, a display control unit 120A, and a setting output. Unit 130 and user confirmation unit 140, which perform various processes. Note that the determination unit 110, the display control unit 120A, and the setting output unit 130 have the same functions as those described in the sixth embodiment, and are omitted here.

  The user confirmation unit 140 is a processing unit that confirms a user (for example, a driver) who has boarded the vehicle. Specifically, the user confirmation unit 140 acquires user identification information from the electronic control unit 700 when, for example, the electronic control unit (ECU 700) of the car performs key authentication, and the user identification that matches the acquired identification information. The user is confirmed by specifying the information from the storage unit 250A.

  Alternatively, the user confirmation unit 140 controls the operation of the display control unit 120 </ b> A to display a user confirmation screen on the display unit 300 and confirms the user by a command input from the operation unit 350. For the first confirmed user, the identification information of the user is registered in the storage unit 250A.

  As described above, the in-vehicle electronic device 500B illustrated in FIG. 13 stores the operation setting history for each user in the storage unit 250A, and when the user is confirmed by the user confirmation unit 140, Whether the condition is satisfied can be easily determined from the operation setting history. As a result, a plurality of users can perform operation settings of the above-described devices according to individual preferences, and therefore it becomes easier to enhance the convenience and comfort of the vehicle than the in-vehicle electronic device 500A of FIG.

  Next, with reference to FIG. 14, when a device that can be set by the user among devices controlled by the electronic control unit operates differently from the normal operation setting screen of the device is automatically displayed. The configuration of the in-vehicle electronic device when adding the function to be described will be described.

  FIG. 14 adds a function for automatically displaying an operation setting screen of a device that can be set by a user among devices that are controlled by the electronic control unit. It is a block diagram which shows the structure of the vehicle-mounted electronic device in a case.

  As shown in FIG. 14, the on-vehicle electronic device 500 </ b> C includes an interface unit 100, a control unit 200 </ b> C, a storage unit 250 </ b> B, a display unit 300, and an operation unit 350. The lamp 610, the rheostat 620, the head lamp 630, the illuminance sensor 640, the shift lever 650, and the parking brake 660 are connected to each other.

  Of these, the interface unit 100, the display unit 300, the operation unit 350, the ECU 700, the room lamp 610, the rheostat 620, the headlamp 630, the illuminance sensor 640, the shift lever 650, and the parking brake 660. 7 has the same function as that described with reference to FIG. 7, and therefore description thereof is omitted. Here, the control unit 200C and the storage unit 250B having functions different from those in FIG. 7 will be described.

  The storage unit 250B stores data and programs necessary for various processes performed by the control unit 200C, and stores standard operation models such as devices and sensors connected to the ECU 700. For example, the storage unit 250B includes a room lamp 610 determined according to the standard operation model, the brightness outside the vehicle, and the rheostat when the headlamp 630 is lit and not lit for the operation of the rheostat 620. 620, the brightness values (reference values) of the headlamps 630, and the like are stored.

  The control unit 200C has an internal memory for storing a control program such as an OS (Operating System), a program defining various processing procedures, and necessary data, and a determination unit 110, a display control unit 120A, and a setting output. Unit 130 and operation comparison unit 150, which perform various processes. Note that the determination unit 110, the display control unit 120A, and the setting output unit 130 have the same functions as those described in the sixth embodiment, and are omitted here.

  The operation comparison unit 150 constantly obtains information on the operation status of the device from the EUC 700 and compares it with the standard operation model in the storage unit 250B. When there is a device that operates differently from the standard model, the operation comparison unit 150 performs the operation of the display control unit 120A. Control is performed to display on the display unit 300 a guide screen indicating that the operation of the device can be set.

  For example, the operation comparison unit 150 creates standard operation models for the operation of the rheostat 620 when the headlamp 630 is lit and when the headlamp 630 is not lit, and stores them in the storage unit 250B. In this case, when the operation of the rheostat 620 is set by the user so that the meter illuminance becomes equal to or higher than the condition value when the headlamp 630 is turned on, a guide screen for prompting resetting can be displayed on the display unit 300.

  Further, the operation comparison unit 150 acquires the reference values of the room lamp 610, the rheostat 620, and the headlamp 630 at the brightness outside the vehicle detected by the illuminance sensor 640 from the storage unit 250B, and the acquired reference values It is possible to compare the setting value that is actually set and operated, and display on the display unit 300 a guide screen that prompts the user to reset the setting value for which the comparison result is equal to or greater than a predetermined threshold value (bright or dark).

  As described above, the in-vehicle electronic device 500C illustrated in FIG. 14 has the same technical effect as the in-vehicle electronic device 50A (see FIG. 1) described in the first embodiment. Furthermore, since the guide screen indicating that the operation setting is possible when the device operates differently from the standard model is automatically displayed on the display unit 300, there is an error in the content of the operation setting performed by the user. Sometimes it can be urged to reset. Therefore, according to this in-vehicle electronic device 500C, it becomes easier to enhance the convenience and comfort of the vehicle.

  Next, the configuration of an in-vehicle electronic device to which a function as an audio visual device is added will be described with reference to FIG. FIG. 15 is a block diagram illustrating a configuration of an in-vehicle electronic device to which a function as an audio visual device is added.

  As shown in FIG. 15, the in-vehicle electronic device 500D includes a first interface unit 100, a second interface unit 190, a control unit 200D, a storage unit 250A, a display unit 300, an operation unit 350, and a speaker unit 400. And an information reading unit 450, which are connected to the room lamp 610, the rheostat 620, the headlamp 630, the illuminance sensor 640, the shift lever 650, and the parking brake 660 via the ECU 700.

  The first interface unit 100, the second interface unit 190, the control unit 200D, the storage unit 250A, the display unit 300, the operation unit 350, the speaker unit 400, the information reading unit 450, and the ECU 700 shown here. The room lamp 610, the rheostat 620, the headlamp 630, the illuminance sensor 640, the shift lever 650, and the parking brake 660 have the same functions as the in-vehicle electronic device 500D shown in FIG.

  The determination unit 110 of the control unit 200D of the in-vehicle electronic device 500D has the same function as that of the sixth embodiment, that is, based on whether the operation unit 350 detects a user operation or information acquired from the ECU 700. It has a function of determining whether or not there has been an environmental change in which it is recommended to change the switch operation setting.

  Such an in-vehicle electronic device 500D includes an information acquisition unit in which the second interface unit 190 and the information reading unit 450 acquire image information and musical tone information from a removable medium and a device outside the vehicle, or a vehicle from a device outside the vehicle (GPS system). Therefore, it also functions as an audio visual device such as a television receiver, a music player, or a car navigation device. Therefore, the same technical effect as that of the on-vehicle electronic device 50A described in the first embodiment can be obtained, and the convenience and comfort of the vehicle can be improved compared to the on-vehicle electronic device 50A (see FIG. 1) described in the first embodiment. Becomes even easier.

  The on-vehicle electronic device according to the present invention has been described with reference to the embodiments. However, as described above, the present invention is not limited to the above-described embodiments. For example, the guide screen displayed on the display unit may be a separate screen from the operation setting screen, or may also serve as the operation setting screen. Furthermore, the operation setting screen itself may be used. Also, the function for displaying the operation setting screen can be omitted. However, from the viewpoint of enhancing the convenience of the in-vehicle electronic device, it is preferable to use the in-vehicle electronic device as an input device of the electronic control unit of the car. For this purpose, a function for displaying an operation setting screen and an operation setting command are provided. It is preferable to add a function that can be output to the electronic control unit to the on-vehicle electronic device.

  When a function as a car navigation device is added to the in-vehicle electronic device, it is possible to set the operation of the auto cruise control when it is detected from the vehicle position information and the map information that the vehicle has entered the expressway. It is also possible to configure the in-vehicle electronic device so that the guide screen shown is displayed on the display unit. That is, it is possible to configure the on-vehicle electronic device so that the “predetermined condition” described in the first embodiment is satisfied when the car enters the expressway. The vehicle-mounted electronic device according to the present invention can be variously modified, modified, combined, etc. in addition to those described above.
