  Hereinafter, embodiments for carrying out the present invention will be described with reference to the accompanying drawings.

  As shown in FIG. 1, the vehicle information processing apparatus 1 according to this embodiment includes a car navigation ECU 2 (Electronic Control Unit) and a display 3. The car navigation ECU 2 is connected to a brake ECU (not shown) of the vehicle and other ECUs such as EPSECU (Electronic Power Steering) according to a communication standard such as CAN (Controller Area Network).

  The car navigation ECU 2 includes, for example, a CPU, ROM, RAM, EEPROM, a data bus connecting them, and an input / output interface. In this embodiment, as shown in FIG. 2, an application α (car navigation application) as one application (content) and an operating system positioned below the application α (car navigation application) are stored in advance in the EEPROM of the car navigation ECU 2 at the time of manufacture, for example. Has been.

  In this embodiment, the application β (phone application) is illustrated as another application. The application β is added as an option at the time of vehicle purchase, for example, or installed and added later by downloading the user β or purchasing a DVD. In the present embodiment, an input component (UI component: User Interface) that is allowed to be displayed during traveling among a plurality of elements on the screen.

  In the car navigation ECU 2, the CPU performs a predetermined process in accordance with the application α, the application β, and the operating system program. The car navigation ECU 2 constitutes an acquisition means 2a that performs processing described below, a display means 2b, a storage means 2c, a determination means 2d, a calculation means 2e, a restriction means 2f, and a search means 2g. .

  The brake ECU includes, for example, a CPU, a ROM, a RAM, a data bus connecting them, and an input / output interface. The CPU performs predetermined processing according to a program stored in the ROM.

  The brake ECU detects the vehicle speed V based on an output signal from a wheel speed sensor (not shown), and outputs the detection result of the vehicle speed V to the car navigation ECU 2 via the CAN. Further, the brake ECU outputs to the car navigation ECU 2 a release signal that is determined based on the driver's operation of the parking brake and that indicates that a parking brake device (not shown) has been released. The acquisition means 2a of the car navigation ECU 2 acquires the vehicle speed V and the release signal as information on the running state of the vehicle.

  In this embodiment, the display means 2b displays UI parts (input parts) on the screens of one and other applications on the screen of the display 3. The storage unit 2c reads out the UI component type (in this example, “button”, “text”, “tenkey”) and prioritizes one application for each input component type (regulatory element) with other applications. The degree is set and stored as shown in FIG. The entire display component on the screen is referred to as a “drawing component” (a plurality of elements). The UI component is a component for the driver to input on the screen, and is a subordinate concept of the drawing component. The drawing component is simply a superordinate concept including components for drawing such as a map and a background.

  In this embodiment, the application α (car navigation application), which is one application, is installed in advance, and when another application (application β: telephone application) is installed, the storage means 2c is an input component. The priority between applications is set for each type.

  The discriminating means 2d of the car navigation ECU 2 determines whether or not the travel regulation is to be performed from the travel state information (the vehicle speed V and the release information described above) acquired from the other ECU of the vehicle. The discriminating means 2d determines that the vehicle speed V> 0 or release information is present (condition that the running state is other than the stopped state: in this embodiment, the running state includes the stopped state for convenience of definition). It is supposed to regulate driving.

  In this travel restriction, the determination unit 2d of the car navigation ECU 2 determines whether the UI part is a restricted part whose display is restricted or a prohibited part whose display is prohibited. In the UI parts exemplified in this embodiment, the restricted parts are “buttons” and “text”, and the prohibited parts are “tenkeys”.

  In this embodiment, as shown in FIG. 3, “application α” is set to have a higher priority than “application β” for “button” which is one of the restricted parts. This is because the “button” in the car navigation app that is the app α has higher operational priority than the “button” of the phone app that is the app β, and it is necessary to increase the priority (priority). Based.

  Further, “application β” is set to have higher priority than “application α” for “text”, which is the other of the restricted parts. This is because the “text” in the phone app, which is the app β, is more urgent than the “text” in the car navigation app, which is the app α (which is often stationary road information), so the priority is increased. Based on the need arises. Note that the “ten-key” is a prohibited part and is always hidden when travel regulation is performed.

  In the case where the application α and the application β are simultaneously displayed based on the screen division function of the display means 2b of the car navigation ECU 2, the restriction contents for each type when the travel restriction is performed are as shown in FIG. For example, “button number is within the button number restriction value NBmax”, “text” is, for example, “number of characters is within the character number restriction value NTmax”, and “number key” is “not displayable”. is there.

  In this embodiment, the application β is a telephone application, and when the driver wants to make a call himself, when the user performs a predetermined operation on the screen of the display 3 or when a call comes from the other party, the application β On the other hand, the process for interrupting the application β is performed, and the display means 2b divides the screen. For example, as shown in FIG. 5, the display means 2b displays the application β on the upper half of the screen of the display 3, and displays the application α on the lower half.

  The screen of the normal car navigation system is displayed on the screen of the lower half application α, that is, the car navigation application. The functions and screen display of the car navigation system are briefly described below. As a well-known function, the search means 2g of the car navigation ECU 2 determines the main position of the vehicle based on, for example, the principle of triangulation based on radio waves from a plurality of satellites launched on the earth received by a GPS antenna (not shown). The current position PP of the vehicle is detected by measuring the longitude and latitude.

  At the same time, the search means 2g of the car navigation ECU 2 detects the yaw rate of the vehicle based on the output of a yaw rate sensor (not shown). Furthermore, the search means 2g detects the steering angle detected by the EPS ECU (not shown) based on the output of the steering sensor provided in the EPS (not shown) via the CAN. The search means 2g calculates the current position PP for vehicle complementation by autonomous navigation (INS), and the vehicle position cannot be detected based on the principle of triangulation by receiving telephone calls from a plurality of satellites of the GPS antenna. The information of the current position PP is complemented.

  Further, the search means 2g includes map information for search included in a database (not shown) that includes a destination input from the touch panel formed on the screen of the display 3 and a current position PP of the current vehicle to the destination R. To search by appropriate means such as Dijkstra method. The display means 2b of the car navigation ECU 2 superimposes the searched route R, the current position PP, and the display map information included in the database, and displays them using the lower half screen of the display 3.

  Here, the screen shown in FIG. 5 shows a case where it is not determined that the “running regulation” is performed by the determination unit 2d. Based on the display function of the display means 2b, road information such as “note that this accident has occurred frequently” is displayed as “text” at the upper end of the lower half of FIG. Here, it is assumed that the number of characters of the application α is NTα. In addition, “buttons” for selecting functions such as “detail”, “OFF”, “G”, “display change”, “point registration”, and “wide area” are displayed at the lower end. Here, the number of buttons of the application α is NBα.

  The display means 2b uses the upper half screen of the display 3 to display the application β, that is, the image for the telephone application. In the image for the phone application, “Dial” is displayed at the upper left, “Phone Book” is displayed at the center in the up and down direction, and “Back” function selection “Button” is displayed at the upper right. Here, the number of buttons of the application β is NBβ. Furthermore, for example, “text” “Enter phone number” is displayed between “dial” and “phone book” in the vertical direction. Further, the number of characters NTβ of the application β is assumed. In addition, a “numeric keypad” is displayed at the center of the upper screen between the “phone book” and “back” buttons.

  When it is determined that the UI part is a restricted part, the calculation unit 2e of the car navigation ECU 2 determines the information amount (the number of buttons, the number of buttons, and the “text”) of the UI part (“button”, “text”) corresponding to the restricted part. The sum ΣNB = NBα + NBβ and ΣNT = NTα + NTβ is calculated. When the sum ΣNB, ΣNT calculated by the calculation means 2e exceeds the regulation values NBmax, NTmax shown in FIG. 4, the limit means 2f of the car navigation ECU 2 limits the display from the UI component with the lower priority. Thus, the sum after the restriction is within the regulation value. In addition, when the other application (in the case of an application other than the application β) does not include the UI component, the restriction unit 2f hides the other application in the travel restriction.

  That is, the display of the screen after the travel restriction is performed is as shown in FIG. 6 with respect to FIG. 5 before the travel restriction. First, the “numeric keypad” is not displayed. Here, for the sake of illustration, FIG. 6 shows a case where the sum ΣNB, ΣNT exceeds the regulation values NBmax, NTmax shown in FIG. In other words, when the total number of buttons ΣNB> NBmax, the priority among the “buttons” of the low-priority apps β based on the priorities shown in FIG. 3 set and stored by the storage unit 2c. The “return” “button” having the lowest value is hidden by the limiting means 2f, and the excess of the total regulation value is resolved.

  When the total number of characters of “text” ΣNT> NTmax, “text” of the application α having a low priority is not displayed based on the restriction of the restriction means 2f based on the priority shown in FIG. The Note that “text” is generally not displayed because it does not make sense to reduce the number of characters. That is, the UI parts in the area surrounded by the three broken lines shown in FIG. 5 are not displayed in FIG.

  Hereinafter, the control content of the vehicle information processing apparatus 1 of the present embodiment will be described in detail with reference to the flowchart shown in FIG. In step S1 shown in FIG. 7, the storage unit 2c determines whether another application has been added. If the result is affirmative, the process proceeds to step S2. If the result is negative, the process proceeds to END.

  In step S2, the storage unit 2c reads out information regarding the type of UI component from another added application, and in step S3, the storage unit 2c reads the one as illustrated in FIG. Set the priority for each type between the application and other applications.

  In step S4, the acquisition means 2a acquires information on the driving state, and the determination means 2d determines whether or not the travel restriction is performed other than the stop state from the information on the driving state of the vehicle. If no, proceed to END. In step S5, the determination unit 2d acquires content (information on drawing parts including UI parts) to be displayed from both one application and another application. In the present embodiment, content is synonymous with application.

  Step S6 indicates the beginning of the first loop A, and step S15 indicates the end of the first loop A. That is, the processing from step S6 to step S15 is repeatedly executed for each content by the number of contents.

  In step S7, the determination unit 2d determines whether or not the drawing component constituting the screen includes the UI component. If the determination is negative, the process proceeds to step S8, and the restriction unit 2f includes the content that does not include the UI component. Process to hide.

  If the result is affirmative in step S7, the process proceeds to step S9, and the determination unit 2d acquires UI part information including the type of UI part.

  Step S10 indicates the beginning of the second loop B, and step S14 indicates the end of the second loop B. That is, the processing from step S10 to step S14 is repeatedly executed for each UI component.

  In step S11, the determination unit 2d performs “UI component determination” as to whether or not the UI component is a restricted component. If NO, the process proceeds to step S12 to display a non-restricted UI component, that is, a prohibited component non-display process. If YES, the process proceeds to step S13, and the UI part information of the UI part that is a restricted part is stored.

  Step S16 is the beginning of a third loop C that is executed after the repetition of loop A and loop B, and step S19 is the end of loop C. For example, in the example shown in FIG. 3 described above, the number of contents in step S6 is two, the number of UI parts in step S10 is two, and the number of UI part information in step S16 is four in this example, and this number of loops C is repeatedly executed.

  In step S17, the calculation means 2e calculates the total information amount for each UI component, that is, the above-described sum ΣNB, ΣNT, and determines whether or not the corresponding regulation value NBmax or NTmax is exceeded. If this determination is affirmative, the process proceeds to step S18, and the limiting means 2f performs the non-display process for the required number of parts from the UI parts with low priority, and if not, the process proceeds to step 19 and the number of repetitions described above. After execution, proceed to END.

  According to the vehicle information processing apparatus 1 of the present embodiment realized by the control contents described above, the following operational effects can be obtained. That is, in the case where a plurality of contents (applications) are displayed on the display while traveling simultaneously, for example, the priority shown in FIG. 3 and the travel regulation shown in FIG. It can be executed based on the rules.

  In other words, when a plurality of applications are divided and displayed at the same time, in this embodiment, it is determined whether or not the UI component is subject to travel regulation, particularly the operation contents and display contents of the other application. It can be performed based only on the priority between applications for each type of UI component. For this reason, the necessity for the vehicle information processing apparatus 1 and the inconvenience that the processing load increases can be avoided. Even when simultaneous display is performed, UI parts with low priority are not displayed on the basis of priority, so this embodiment is intended to ensure both safety by driving regulation and compatibility between driver operability and convenience. be able to.

  Although the preferred embodiments of the present invention have been described in detail above, the present invention is not limited to the above-described embodiments, and various modifications and substitutions are made to the above-described embodiments without departing from the scope of the present invention. be able to.

  For example, in the above-described embodiment, the parts fixedly displayed on the screen such as “button”, “text”, and “numeric keypad” are exemplified as the UI parts, but a combination of operations on the screen can be included in the UI parts. For example, “flick operation” in which a page in the screen is scrolled by “flick” with a finger left and right on the screen and then “touch” is performed to fix the page again is included in the UI component. It can also be handled as a regulated part.

  In the embodiment described above, the ECU that executes the operating system mainly implements each functional unit. However, the ECU that executes one application may naturally implement each functional unit. Moreover, it is good also as a system with which one application and an operating system are comprised integrally.

  Further, in the vehicle information processing apparatus shown in the above-described embodiment, a case where one application and another application are paired is shown, but also when there are two or more other applications for one application The flowchart shown in FIG. 7 of the present invention can be applied as it is.

  The present invention relates to a vehicle information processing apparatus to which travel restrictions on screen display are applied, and by setting a priority for each application for each type of input part included in a plurality of stored applications, Appropriate travel regulation can be realized, which is useful when applied to various vehicles such as passenger cars, trucks, and buses.
