Description

  The present invention relates to a vehicle operation device that displays content on a display device and receives an operation on the content.

  A vehicle is equipped with a display device for displaying content represented by an operation screen of an audio visual device or a setting screen of an in-vehicle device such as an air conditioner. Although it has been studied to display a plurality of contents on one display device as the contents increase, the number and types of contents displayed on the display apparatus at the same time are expected to increase. In addition, it is expected that the screen size of the display device mounted on the vehicle will increase as the types of content increase. If the screen size is increased, it is considered that the types of contents displayed on one display are increased.

  By the way, many contents are able to accept occupant operations on each content, and perform processing such as accepting settings and switching screens according to occupant operations. If a hard key to which different operation details are assigned for each key is provided as a user interface for receiving an operation, the number of hard keys corresponding to the type of operation details that can be received by the content is required.

  For this reason, software of user interfaces has been progressing conventionally, and each content often displays a soft key on a display device in order to accept an occupant's operation on the content. The occupant individually operates the content by touching a display device integrally formed with a touch panel. However, it is a burden on the driver that the display device is in a place where it is difficult for the driver to reach or the user needs to watch the screen for operation.

  For this reason, some vehicles have conventionally been provided with general-purpose operation receiving means such as a cross key at a place where the driver can operate without looking, for example, around the steering wheel or console box. Such an operation accepting unit has, for example, a selection key for selecting a soft key, an enter key, and the like, and can accept an operation regardless of the type of content. The content side associates the soft key displayed when the occupant operates with the operation content of the operation accepting means, and accepts the operation with the selection key and the decision key in the same manner as when the soft key is operated.

  However, when a plurality of contents are displayed on one display device as described above, it is difficult to determine which contents the occupant has operated the operation receiving means. As one method, when a plurality of contents are displayed on one display device, it is conceivable that the occupant selects the contents to be operated in advance by the operation receiving means or the like. In this method, the occupant can select the contents with certainty, but the number of operations that the occupant has to perform increases.

  In addition, a technique is conceivable in which the direction in which the driver is gazing is detected and content is specified (see, for example, Patent Document 1). In Patent Document 1, in-vehicle devices provided in a plurality of locations of a vehicle, first pupil detection means for detecting the direction of the driver's pupil and generating pupil direction data indicating the direction of the pupil, and pupil direction data Based on the above, an in-vehicle electronic device that specifies which in-vehicle device among a plurality of in-vehicle devices the part that the driver is gazing at and selects the specified in-vehicle device as a control target is disclosed. ing.

  However, in the method for selecting an in-vehicle device disclosed in Patent Document 1, it is possible to detect which content in the display device the pupil is facing even if it is possible to detect that the pupil is facing the display device. Have difficulty. In addition, a camera or an image processing device for detecting the orientation of the pupil is required.

  In view of the above problems, an object of the present invention is to provide a vehicular operating device capable of selecting a content to be operated from a plurality of contents displayed at the same time.

  The present invention is a vehicular operating device that receives an operation on content displayed on a display device, the display control means for dividing the display device into a plurality of regions and displaying a plurality of contents simultaneously, The operation content acquisition means for acquiring the operation content from the operation reception means commonly used for the operation, the vehicle status detection means for detecting the vehicle status, and the priority of each content displayed by the display control means Content determining means that changes according to the vehicle status and determines the content to be notified of the operation details based on the priority.

  It is possible to provide a vehicular operating device capable of selecting a content to be operated from a plurality of contents displayed at the same time.

The vehicular operating device 100 includes a general-purpose operation receiving unit 150 that receives operations for a plurality of contents, a display 200 that can display a plurality of contents at the same time, and what content the operation content received by the general-purpose operation receiving unit 150 is for. And an input control unit 60 to be selected.

  The input control unit 60 has priority data in which the priority order of contents is registered according to the vehicle situation. For example, in the vehicle situation I, the priority is higher in the order of contents A → B → C → D, and in the vehicle situation II, the priority is higher in the order of contents C → D → A → B.

  When the operation content accepted by the general-purpose operation accepting unit 150 is acquired, the input control unit 60 detects the vehicle situation, refers to priority data suitable for the vehicle situation, and determines the priority of the content. Then, in consideration of each content displayed on the display 200 and the operation content that can be received, the content (application) for notifying the operation content is determined and output.

  Therefore, in the vehicle operation device 100 according to the present embodiment, the general-purpose operation reception unit 150 is operated even if the content to be operated by an occupant (hereinafter, the occupant includes a driver) is not selected in advance. In this case, it is possible to accept an operation for one content from among a plurality of contents displayed on the display 200. In addition, a device for detecting the pupil and the line of sight is unnecessary.

[Configuration example]
FIG. 2 shows an example of a schematic configuration diagram of the vehicle operating device 100. The vehicle operation device 100 includes an information processing unit 49 and various peripheral devices 48. The information processing unit 49 includes a control unit 50 and various functional units (GPS signal processing unit 31 to display control unit 46), and the entire operation is controlled by the control unit 50. The control unit 50 includes at least one of a microcomputer, an IC, and an ASIC including a CPU, a RAM, a ROM, an I / O, and the like. The control unit 50 controls each peripheral device and provides a characteristic function to the vehicle operation device 100 described later.

  The GPS antenna 11 receives radio waves from at least three GPS satellites and outputs them to the GPS signal processing unit 31. The GPS signal processing unit calculates the distance from the GPS signal to each GPS satellite and measures the position (latitude, longitude, altitude) of the vehicle by a predetermined calculation. The detected position information is used in the navigation system. The control unit 50 estimates an accurate position starting from the coordinates detected by the GPS signal processing unit 31 even when a radio wave cannot be received by using detection signals of an in-vehicle sensor and an internal sensor 36 described later for autonomous navigation. .

  The broadcast antenna 12 receives radio (AM / FM) and digital television radio waves and outputs them to the broadcast receiver 32. The broadcast receiving unit 32 includes a tuner circuit and a detection circuit, for example, demodulates a radio or television channel signal selected by the passenger and outputs the demodulated signal to the control unit 50.

  The peripheral camera 13 is a camera that captures the periphery of the host vehicle, such as a back monitor camera, a side camera disposed on a door mirror, and a front camera that captures the front. The image input unit 33 controls the gain, shutter speed, and the like of the peripheral camera 13, performs γ correction, noise removal, distortion correction, and the like on the image data captured by the peripheral camera 13 and outputs the image data to the control unit 50. When a plurality of cameras are mounted, the image output by the image input unit 33 is automatically selected according to the vehicle situation, and can be arbitrarily selected by the occupant.

  The external device 14 may be any device as long as it can be connected to the external device I / F 34. For example, a portable music player, a smartphone, a mobile phone, a notebook computer, a tablet, and the like. The external device I / F 34 is, for example, a USB host, a Bluetooth (registered trademark) module, a wireless LAN communication module, or the like. The external device I / F 34 outputs music data received from the external device to the control unit 50.

  The on-vehicle sensor 15 is various sensors mounted on the vehicle, and is directly connected to the information processing unit 49. In addition, various in-vehicle sensors are mounted on the vehicle, and a detection signal detected by the in-vehicle sensors is acquired by the information processing unit 49 via an in-vehicle communication device 38 described later. The in-vehicle sensor 15 is, for example, a wheel speed sensor, a parking brake switch, a stop lamp switch, a lever operation position sensor, a three-axis gyro sensor, a yaw rate sensor, or the like. The vehicle situation can be detected by the in-vehicle sensor 15. The sensor signal input unit 35 outputs each detection signal of the in-vehicle sensor 15 to the control unit 50. In addition, the information processing section 49 has a built-in internal sensor 36, and even if it is not connected to the in-vehicle sensor 15, a minimum navigation is possible. The internal sensor 36 is a three-axis gyro sensor, for example, and enables the above-described autonomous navigation.

  A DCM (Data Communication Module) 16 is a communication device that performs data communication with a server via a wireless communication network such as a mobile phone network, a wireless LAN network, and a WiMax network. Data received by the DCM 16 is output to the control unit 50 by the DCM I / F 37. The DCM I / F 37 adds or removes a header according to the communication protocol and outputs the received data to the control unit 50. There are various types of data received by the DCM 16, and examples include road map data, music data, and web pages.

  The in-vehicle communication device 38 is a communication device that communicates with the electronic control unit connected to the in-vehicle LAN. Communication standards for in-vehicle LANs include CAN (Controller Area Network), FlexRay, Lin (Local Interconnect Network), Ethernet (registered trademark), and the like. The in-vehicle communication device 38 directly receives a detection signal from another sensor that is not detected by the connected in-vehicle sensor 15 via the in-vehicle LAN. For example, various data flowing through the in-vehicle LAN, such as engine speed, fuel consumption, accelerator opening, air conditioner set temperature, and actual room temperature, can be received. Further, the operation content set by the occupant at the general-purpose operation reception unit 150 is output to the in-vehicle LAN as necessary.

  The HDD 17 stores programs and data. The program is an application, OS (Operating System), middleware such as a device driver, etc., which will be described later. The program also includes a function for determining an application for notifying the operation content received by the general-purpose operation receiving unit 150. The data stored in the HDD 17 is, for example, road map data, music data, video data, data downloaded from the DCM 16 from the outside, and the like. The HDD I / F 39 writes the data instructed by the control unit 50 to the HDD 17 and outputs the data from the HDD 17 to the read control unit 50.

  The microphone 18 collects a voice uttered by the occupant, converts it into an electrical signal, and outputs it to the voice processing unit 41. The sound processing unit 41 converts the electrical signal into digital data using PCM or the like and outputs the digital data to the control unit 50. In addition, the voice processing unit 41 may perform voice recognition. As a result, voice operation of the in-vehicle device can be performed. The control unit 50 causes the voice processing unit 41 to start voice processing when the general-purpose operation receiving unit 150 receives an operation of a voice recognition button.

  The Blu-Ray drive 19 is an optical disk mounting portion that can mount an optical disk such as a CD, a DVD, and a Blu-Ray. The Blu-Ray drive reads a signal from the optical disc and outputs data such as music and video to the drive I / F 42. The drive I / F 42 outputs data such as music and video to the control unit 50.

  The music playback unit 43 decodes music data (MP3, WAVE, etc.) acquired by the broadcast receiving unit 32, the external device I / F 34, the DCM I / F 37, the HDD I / F 39, the drive I / F 42, etc. according to the format. Output to the control unit 50. The control unit 50 outputs the decoded music data from the speaker 21 via the amplifier 44.

  The video playback unit 45 decodes video data acquired by the broadcast receiving unit 32, the external device I / F 34, the DCM I / F 37, the HDD I / F 39, the drive I / F 42, etc. according to the format, and outputs the video data to the control unit 50 To do. The control unit 50 causes the display control unit 46 to display an image. The display control unit 46 draws an image based on the video data by driving the thin film transistors equally arranged in a grid pattern of the display 200. Further, the display control unit 46 can divide the display 200 into several regions and display a plurality of contents on the display 200 at the same time according to an instruction from the control unit 50. Whether to display a single content or a plurality of contents can be switched by the control unit 50 according to the vehicle situation, or can be arbitrarily switched by the user operating the general-purpose operation receiving unit 150, for example. is there.

  The display 200 is a flat panel display such as a liquid crystal display or an organic EL display. The size of the display 200 is increased, for example, from about 4 inches to 10 inches or more. Since the resolution is improved, one display 200 can be divided into a plurality of regions regardless of the size. The display 200 is disposed on, for example, a center console or a dashboard. The display 200 is disposed on the center console or the dashboard so as to be openable and closable, and may be retractable except when in use. Two or more displays 200 may be provided, and another display may be arranged in a meter panel or the like. That is, in the present embodiment, it is possible to select one application from a plurality of applications displayed on the plurality of displays 200.

  Further, the display 200 may be a projection type, and may be a project that projects an image on a center console or the like, a HUD (Head Up Display) that projects an image on a window shield or the like.

  Various hard keys are arranged around the display 200, and a touch panel is integrally provided. The operation position detection unit 22 detects the operation position of the passenger on the touch panel and notifies the control unit 50 of the operation position. The control unit 50 identifies the operated soft key based on the operation position. The hard keys are a current location button, a volume adjustment button, a menu button, and the like.

  The general-purpose operation reception unit 150 receives an occupant's operation on the information processing unit 49 and notifies the control unit 50 of the operation content. Details will be described later.

[General-purpose operation reception part]
FIG. 3 shows an example of a schematic perspective view of the general-purpose operation reception unit 150. The general-purpose operation reception unit 150 is disposed at a position where the occupant can operate with a thumb or the like while holding the steering wheel in a neutral steering wheel, for example. The occupant can operate a plurality of contents (music player screen, air conditioner screen, cruise control screen, etc.) displayed on the display 200 by the general-purpose operation receiving unit 150. Conventionally, although depending on the vehicle type, etc., dedicated steering switches have been prepared for audio, air conditioning, and cruise control, respectively. In the present embodiment, these are preferably integrated into one general-purpose operation receiving unit 150. Alternatively, it is possible to reduce at least the type and mounting space of the switch.
The cross key 151 accepts operations in four directions (up / down / left / right) for the content.
The decision key 152 accepts the decision of the selected menu etc. The return key 153 accepts an operation to return the content to the previous state. The mode key 154 accepts the selection of the content. The volume buttons 155 and 156 increase or decrease the volume. As described above, the operation contents that can be received by each key of the general-purpose operation reception unit 150 are general-purpose, and can be commonly used when the occupant operates a plurality of contents. The operations that each key is interpreted as in each content are defined by the content. Further, depending on the content, there is a key where the operation of the general-purpose operation receiving unit 150 is invalid, and there is a key where the validity / invalidity of the operation varies depending on the screen even for the same content. As will be described later, the input control unit 60 is notified of operation details that can be received by the content.

  In the present embodiment, a description will be given of processing for mainly notifying the content of operation of the cross key 151 (that is, operation in four directions, up, down, left, and right).

  Note that the general-purpose operation receiving unit 150 does not have to be a steering switch disposed on the steering wheel. That is, it is sufficient that the occupant does not need to move the line of sight at all while maintaining the driving posture or may be disposed at a position where it can be operated without a large movement of the line of sight.

  FIG. 3B is a diagram illustrating an example of a lever switch type general-purpose operation receiving unit 150. The general-purpose operation reception unit 150 is disposed around the center console box between the passenger seat and the driver seat. The lever 160 is configured to be able to swing in a total of eight directions, in addition to up, down, left and right.

  In addition, a dial-type general-purpose operation reception unit 150 that sequentially selects a touch pad, a menu, and the like that detect a user's operation position on a predetermined area is known, and FIGS. 3A and 3B are general-purpose. The configuration of the operation reception unit 150 is not limited.

  The general-purpose operation receiving unit 150 may be configured by voice recognition using the microphone 18 and the voice processing unit 41. That is, the occupant utters “Up”, “Down”, “Right”, “Left” while pressing the voice recognition button, and the voice processing unit 41 recognizes the utterance content as a voice. The same operation content as when the cross key of section 150 is operated is accepted.

[Example of display division]
FIG. 4 is an example of a diagram for explaining a division example of the display 200. In FIG. 4A, one display 200 is divided into four areas. A browser screen is displayed in area 1, an air conditioner screen is displayed in area 2, a music player screen is displayed in area 3, and a fuel consumption screen is displayed in area 4. ing. The display content of each screen is the content. Description will be made assuming that the content is created by the application, and the application and the content correspond one-to-one.

  The occupant can arbitrarily set the correspondence between the area and the displayed content. Further, when there are more types of content than the number of areas, the passenger can arbitrarily select the content to be displayed with priority over the display 200. Further, content that cannot be displayed simultaneously is displayed when the user operates the general-purpose operation reception unit 150, for example. When a plurality of contents are arranged in a tile shape on the display 200 as shown in FIG. 4A, the number of contents displayed simultaneously can be increased by reducing the screen of each content or increasing the size of the display 200. can do. In addition, it is possible to enlarge the contents screen and reduce the number of contents displayed simultaneously. That is, the number of contents displayed simultaneously may be less than 4 or 5 or more. Note that the screen size of each content need not be the same.

  FIG. 4B is a diagram showing another example of content arrangement. Each content is displayed in a horizontal row. Thus, the content arrangement may be suitable for the shape of the display 200 or suitable for the user's preference.

  FIG. 4C shows another example of content arrangement. The air conditioner screen is displayed in a picture-in-picture (PinP) mode on the browser screen. In this way, it is possible to display the main content large and display other arbitrary content (two or more) small.

[Content soft key]
FIG. 5 is an example of a diagram illustrating soft keys included in each content. The browser screen includes, for example, a return button 171, a forward button 172, an update button 173, an up scroll button 174, and a down scroll button 175. The air conditioner screen includes a determination button 185, a small air volume button 183, a large air volume button 184, a small temperature button 182, and a large temperature button 181. The music player screen has a determination button 193, an up scroll button 191, and a down scroll button 192. Since the fuel consumption screen does not need to accept an operation, there is no soft key in FIG. These soft keys are merely examples, and various other soft keys may be provided.

  The operation contents that can be accepted by the contents are generally displayed as soft keys. However, it is not always possible to operate the general-purpose operation accepting unit 150 unless the soft key is displayed, and it is possible to operate a soft key that is not displayed on the general-purpose operation accepting unit 150. For example, even if soft keys that are frequently operated such as the back button 171 and the forward button 172 of the browser are not displayed, the passenger can operate. Further, the degree of freedom in designing the content screen is increased by not displaying the content. The occupant may arbitrarily set whether or not to display the soft key.

  FIG. 5B is an example of a diagram for explaining other content soft keys. The seat screen has an Up button 201, a Down button 202, a front button 203, and a rear button 204. The navigation screen has a detail button 215, a wide area button 216, and four scroll buttons 211-214. The cruise control screen has a + RES button 221, a CANCEL button 222, a −SET button 223, and an ON / OFF button 224. The television screen has a volume down button 233, a volume up button 234, a channel up button 231, and a channel down button 232.

  These are merely examples, and other than those shown, any vehicle-mounted device that can be operated by a passenger can be operated by the general-purpose operation receiving unit 150. For example, the present invention can be applied to switching between passing light distribution and traveling light distribution of a headlight by a headlight application, or switching of a target parking position by a parking support application.

[Correspondence between content soft key and general-purpose operation reception unit]
FIG. 6A is an example of a diagram for explaining the correspondence between the content soft key and the operation content of the general-purpose operation receiving unit 150. Each content associates the operation details of the general-purpose operation reception unit 150 with the operated soft keys in advance. For example, in the case of an air conditioner screen, the small air volume button 183 is associated with the left direction key, the large air volume button 184 is associated with the right direction key, the small temperature button 182 is associated with the down direction key, and the large temperature button 181 is associated with the up direction key. Yes. That is, if only the air conditioner screen is displayed on the display 200, the air conditioner application for creating the air conditioner screen detects that the large air volume button 184 has been pressed if the right direction key is operated, and the up direction key is operated. Then, it is detected that the large temperature button 181 has been pressed.

  FIG. 6B is a diagram showing a list of correspondences between the operation contents of the general-purpose operation receiving unit 150 and the soft keys of the respective contents. The up direction key of the general-purpose operation receiving unit 150 is interpreted as operating the large temperature button 181 on the air conditioner screen, the up scroll button 174 on the browser screen, and the up scroll button 191 on the music player screen. The downward key of the general-purpose operation reception unit 150 is interpreted as an operation of the small temperature button 182 on the air conditioner screen, the down scroll button 175 on the browser screen, and the down scroll button 192 on the music player screen.

  The correspondence between the soft key and the operation content of the general-purpose operation receiving unit 150 is information necessary for the application side to select the soft key according to the operation content, and the input control unit 60 does not need to manage. However, as shown in FIG. 6B, the correspondence between the soft key and the operation content may be managed. The correspondence between the operation content and the content soft key is referred to as an operation content / soft key list.

[Functions of the vehicle operating device]
FIG. 7 shows an example of a functional block diagram of an application that operates on the vehicle operation device 100 and the input control unit 60. Each function of the input control unit 60 is realized by the control unit 50 executing a program and cooperating with peripheral devices.

  The vehicular operating device 100 executes various applications 70 as processes in parallel using the functions of the OS. For example, since an application is repeatedly assigned to a resource such as a CPU every predetermined time, it seems to humans to operate in parallel in time. The OS manages running applications and records application identification information, addresses where applications are stored, and the like.

  Any application may be used, but the illustrated application will be described. The browser application is an application that displays a web page by interpreting, for example, HTML data received by the DCM 16 or the Script language. The air conditioner application is an application that accepts settings for the air conditioner and displays the current setting state. Settings such as temperature and air volume received by the air conditioner application are transmitted to the air conditioner ECU by the in-vehicle communication device 38, and the air conditioner ECU controls the air conditioner to the set temperature and air volume. The music player application is an application for playing music. The music file is stored in the HDD 17, the external device 14, etc., and the title and artist name are displayed on the display 200. When the user selects a music file, the music player application reads the music file and causes the music playback unit 43 to play it. The fuel consumption application is an application that displays the fuel consumption state. For example, fuel consumption and travel distance are acquired via the in-vehicle communication device 38 every predetermined time, and fuel consumption is calculated every unit time (for example, 1 minute, 1 hour, 1 day, 1 trip). This is graphed in time series and displayed on the display 200.

<Determination conditions for the operation notification destination application>
The operation content received by the general-purpose operation reception unit 150 is acquired by the operation content acquisition unit 61. The application determination unit 62 selects a notification destination application that conveys the operation content acquired by the operation content acquisition unit 61.
-Content displayed on the display-Operation content that can be received-Priority data-Determination based on the operation frequency of the application.

<Content displayed on the display>
The content list acquisition unit 66 acquires the content list of the application displayed on the display 200 from the OS or the like. Therefore, the content list acquisition unit 66 holds lists of browser applications, air conditioner apps, music player apps, fuel consumption apps and the like while updating them in real time.

<Operations that can be accepted by content>
In addition, the content list acquisition unit 66 acquires operation contents that can be received by the general-purpose operation reception unit 150 from each application. Alternatively, an operation details / soft key list in which operation details and content soft keys are associated with each other may be acquired.

  The operation contents that can be accepted by the general-purpose operation accepting unit 150 may be different depending on the screen even for the same app. Therefore, the content list obtaining unit 66 may display the app 70 each time a new app 70 is displayed on the display 200. Acquire operation contents that can be accepted every time the screen is switched. For example, in the example of FIG. 6B, the up direction key, the down direction key, the left direction key, and the right direction key are acquired from the air conditioner application, and the up direction key and the down direction key are acquired from the browser screen.

  When the screen of the application 70 does not change or the operation content that can be accepted does not change even if the screen is changed, the input control unit 60 holds in advance the operation content that each application can accept by the general-purpose operation reception unit 150. Also good.

  The fact that the operation contents that can be accepted differs depending on the displayed application 70 is one piece of information for narrowing down the applications that notify the operation contents. For example, as shown in FIG. 6 (b), when the operation content is the left arrow key, the small air volume button 183 corresponds to the air conditioner app, but this operation content is used in the browser app, the music player app, and the fuel consumption app. Not accepted. Therefore, when the operation content is the left arrow key, it can be determined that the app that notifies the operation content is an air conditioner app.

<Priority data>
The vehicle status determination unit 65 determines the vehicle status using the detection signal detected by the in-vehicle sensor 15 and the detection signal received by the in-vehicle communication device 38 as vehicle status determination information. The vehicle status determined in the present embodiment is a vehicle status for determining which content of the content displayed on the display 200 is operated by the general-purpose operation reception unit 150. Examples of the vehicle situation include a traveling state, a stopped state, a highway traveling state, a parking work state, and a night traveling state. For example, the determination method of each vehicle situation is as follows.
Traveling state: Stopping state greater than the value that can be considered as zero vehicle speed: Expressway traveling state where the vehicle speed can be regarded as zero Driving state: The driving position is a highway or an automobile-only road and the vehicle speed is equal to or greater than a threshold value Parking work state: Parking assistance switch is ON, vehicle The position of the vehicle is a parking lot, or the shift lever is in reverse. Night driving state: The illuminance detected by the illuminance sensor is equal to or less than the threshold. The priority data will be described. It is known that frequently used apps are biased according to vehicle conditions. For example, the frequency of operating the television screen is more in the state where the vehicle is stopped than in the state where the vehicle is traveling. The same can be said about the browser screen and the sheet screen. The cruise control screen is operated only when the vehicle is running.

  On the other hand, it is difficult to uniquely determine an app only from the vehicle situation. For example, since there is not necessarily one content that is likely to be operated when the vehicle is stopped, it is necessary to specify one screen among a television screen, a browser screen, and a seat screen.

  Therefore, in the present embodiment, first, the application is divided into several categories, and priority is given to the contents in each category.

FIG. 8A is a diagram illustrating an example of each category and an application included in the category.
The vehicle operation setting system application is a category into which an application for a passenger to make settings for a vehicle is classified, and examples thereof include an air conditioner application, a seat application, a cruise control application, and a parking assistance application. The guidance display system application is a category into which applications for presenting information to the passengers are classified, and includes a navigation application, a fuel consumption application, a mileage display application, and the like. The entertainment application is an application for entertaining the occupant, and includes, for example, a TV application, a music player application, a video display application, and a browser application.

  In the priority data DB 67, the priority of each category is registered for each vehicle situation so that the priority of each category can be changed for each vehicle situation.

  FIG. 8B is an example of a diagram showing priority data stored in the priority data DB 67. The vehicle status and the priority of each category are associated with one priority data. The priority data selection unit 63 selects one of the priority data 1 to 5 based on the vehicle status determined by the vehicle status determination unit 65. For example, in the running state, priority data 1 is acquired. In the priority data 1, since the priority is higher in the order of the vehicle operation setting system application, the guidance display system application, and the entertainment system application, the application determination unit 62 determines the application that notifies the operation content in this order.

  Among the apps 70 displayed on the display 200, an app included in a category selected in descending order of priority according to the vehicle situation is referred to as a “candidate app”. When there is only one candidate app and the candidate app can accept the operation content of the general-purpose operation accepting unit 150, the app that notifies the operation content is determined at this point. For example, when the navigation screen, the fuel consumption screen, the music player screen, and the air conditioner screen are displayed on the display 200 in the running state, the vehicle operation setting system application is only one of the air conditioner apps. Therefore, the operation content is notified to the air conditioner application (when the air conditioner application can accept the operation content of the general-purpose operation accepting unit 150).

<Operation frequency>
The operation frequency will be described. When there are a plurality of candidate apps, or when the candidate app cannot accept the operation content of the general-purpose operation accepting unit 150, the app determining unit 62 uses the operation frequency of the app to determine the app that notifies the operation content. For this reason, the application operation frequency recording unit 64 records the operation frequency of each application and updates it every time it is used.

  FIG. 9 is an example of a diagram illustrating the operation frequency of each application. FIG. 9A shows the operation frequency of each application included in each category in the running state. The operation frequency is the number of operations in the past predetermined period. For example, the predetermined period may be determined in advance as one week, one month, six months, one year, or the like, or an occupant may be able to set an arbitrary period.

  For example, in the running state, the air conditioner application is operated 29 times, the seat application is operated 6 times, the cruise control application is operated 5 times, and the parking support application is operated 0 times. Therefore, in the driving state, if the air conditioner app is displayed, the air conditioner app is selected. If the air conditioner app is not displayed, the seat app is selected. If neither the air conditioner app nor the seat app is displayed, the cruise control app is selected. Is done. Then, when no vehicle operation setting system application is displayed on the display 200 in the running state, one application is selected from the guidance display system application with the second category priority in the same order of operation frequency. .

  Furthermore, in this embodiment, not only the operation frequency of the application is recorded but also the operation frequency of each application is calculated in the vehicle situation. Thereby, it becomes easy to correctly determine an application for notifying operation contents.

  FIG. 9B shows the operation frequency of the vehicle operation setting system application in the highway traveling state. Compared with the running state, the operation frequency of each application is different even in the same vehicle operation setting system application. For example, the cruise control application is most frequently operated on a highway. This is because the passengers often use the cruise control application while driving on the highway.

  FIG. 9C shows the operation frequency of the vehicle operation setting system application in the parking work state. Compared with the running state, the operation frequency of each application is different even in the same vehicle operation setting system application. For example, the parking assistance application has the highest operation frequency in the parking work state. This is because the occupant often uses the parking assistance application in the parking operation state.

  Therefore, by recording the operation frequency of each application in each vehicle situation, the operation content of the general-purpose operation receiving unit 150 can be accurately transmitted to the application.

[Operation procedure]
FIG. 10 is an example of a flowchart illustrating an operation procedure of the vehicle operating device 100. The control unit 50 detects that the general-purpose operation reception unit 150 has been operated, and executes the following processing (Yes in S10).

  The operation content acquisition unit 61 first acquires the operation content from the general-purpose operation reception unit 150 (S20).

  The vehicle status determination unit 65 determines the vehicle status based on the vehicle status determination information periodically or whenever the vehicle status changes (S30).

  The priority data selection unit 63 selects priority data suitable for the vehicle situation and sends it to the application determination unit 62 (S40).

  The application determination unit 62 determines a candidate application by specifying an application displayed on the display 200 from the category with the highest priority in the priority data (S50). There are a plurality of candidate applications, one case, and zero cases.

  And the application with high operation frequency is identified one by one among candidate applications (S60).

  The application determination unit 62 determines whether or not the candidate application specified in S60 can accept the operation content based on the operation content / soft key list (S70).

  If the candidate application can accept the operation content (Yes in S70), the application determining unit 62 determines the candidate application specified in step S60 as an application that notifies the operation content (S80).

  If the candidate app cannot accept the operation content (No in S70), the app determination unit 62 determines whether there are remaining candidate apps in the current category (S90).

  If there are remaining candidate apps in the current category (Yes in S90), the process returns to step S60, and the candidate app having the next highest operation frequency is specified.

  If there is no remaining candidate application in the current category (No in S90), the process returns to step S50, and the application determination unit 62 performs the same process on the application of the category with the next highest priority.

  As described above, the vehicle operation device according to the present embodiment selects an app that is preferentially selected according to the vehicle situation, thereby providing a highly accurate app that notifies the operation content received by the general-purpose operation receiving unit 150. Can be specified. Moreover, since the operation frequency of the application is recorded for each vehicle situation, the application for notifying the operation content can be specified with high accuracy.
