  With the above-described means, the present invention can provide a vehicle display system that optimizes the configuration of the screen displayed to the driver and allows the driver to input operations quickly and easily.

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

  FIG. 1 is a diagram illustrating a configuration example of a vehicle display system according to the present invention. A vehicle display system 100 includes a control unit 1, a screen configuration database 2, a touch panel 3, an proximity sensor 4, and a liquid crystal display 5. The

  The control unit 1 is a computer including a CPU (Central Processing Unit), a RAM (Random Access Memory), a ROM (Read Only Memory), an NVRAM (Non-Volatile Random Access Memory), and the like. Programs corresponding to the configuration changing means 11 are stored in the NVRAM, the programs are expanded on the RAM, and the corresponding processing is executed by the CPU.

  The screen configuration database 2 is composed of one or more data tables stored in a nonvolatile storage means such as a hard disk or a semiconductor memory. For example, the table shown in FIG. 2A includes a button ID field 20 indicating an ID number for identifying an escutcheon button arranged around the liquid crystal display 5 and a software button displayed on the liquid crystal display 5, and each escutcheon. Passenger screen ID field 21 indicating the ID number of the response screen newly displayed when a button or software button is pressed by a person other than the driver, and newly displayed when pressed by the driver This is a response screen table including a driver screen ID field 22 indicating the ID number of the response screen.

  The table shown in FIG. 2B includes a screen ID field 23 indicating the ID number of a response screen that is newly displayed, and a response screen that is displayed when the person who pressed the button is a person other than the driver. Passenger ID field 24 indicating the ID number of the button constituting the button, and button ID field for the driver indicating the ID number of the button constituting the response screen displayed when the person who pressed the button is the driver 25 is a display button table. The display button table in FIG. 2B is referred to when the type of software button to be displayed is changed while the screen ID of the response screen to be newly displayed is made common.

  The response screen table in FIG. 2A displays the response screen D1 when the escutcheon button B1 is pressed by a person other than the driver, and displays the response screen D2 when the escutcheon button B1 is pressed by the driver. In addition, when the escutcheon button B2 is pressed, the response screen D3 is displayed regardless of the person who pressed the button.

  In addition, the table in FIG. 2B shows that the response screen D3 is displayed when a person other than the driver presses the escutcheon button B2 in the response screen D3 newly displayed when the escutcheon button B2 is pressed. The software buttons B9 to B14 are displayed on the top, and the software buttons B14 to B18 are displayed on the response screen D3 when the driver has pressed the escutcheon button B2. Specific examples of the screens D1 to D3 and the buttons B1 to B18 will be described later.

  The touch panel 3 is one of input detecting means for detecting an input by the operator to the screen displayed on the liquid crystal display 5, and may be a transparent panel disposed on the liquid crystal display 5, for example. It may be a panel arranged independently at a position physically separated from the liquid crystal display 5. The input detection means may select a software button on the liquid crystal display 5 via a cursor key or a joystick on a remote controller or an escutcheon button.

  The proximity sensor 4 is an operator detection means for detecting the approach direction of an object that performs an operation input to the touch panel 3. For example, an ultrasonic wave or infrared transmitter and receiver are respectively opposed to the front surface of the touch panel 3. It arrange | positions and it detects that the object which touches the touch panel 3 interrupted | blocked the ultrasonic wave or infrared rays between a transmission part and a receiving part, and detects the approach direction of the object. Further, the proximity sensor 4 may detect the approaching direction of the object by using a reflected wave from the emitted ultrasonic wave or infrared object.

  The operator detection means may be an in-vehicle camera or a capacitive touch sensor. This is because the approaching direction of the object can be detected by processing an image photographed by the camera or by detecting a change in capacitance between the object and the touch sensor. Moreover, you may detect supplementarily that there is no passenger other than a driver | operator using a seating sensor.

  The liquid crystal display 5 is one of display means for displaying a response screen corresponding to the operation input by the operator. For example, the liquid crystal display 5 is provided in a predetermined input detection area (area that accepts touch input) set on the touch panel 3. Menu items (software buttons) are displayed in the corresponding area on the display means.

  The display means may be an organic EL (Electroluminescence) display, a head-up display that projects an image on a windshield, or the like.

  Next, the operator determination unit 10 and the screen configuration change unit 11 included in the control unit 1 will be described.

  The operator determination means 10 is a means for determining the input subject of the operation input. For example, when the escutcheon button or the software button for changing the display screen of the liquid crystal display 5 is input, the proximity sensor 4 The input subject of the operation input is determined based on the detection result.

  In addition, when the input means is a remote controller, the operator determination means 10 is provided with a plurality of receiving parts for signals transmitted from the remote controller, and the position of the remote controller is determined from the intensity or direction of the signal detected by each receiving part. May be calculated to determine the input subject of the operation input.

  Note that the operator determination means 10 may determine the input subject in an operation input other than the operation input for transitioning the screen (referred to as a character selection input or a vertical scroll of a list display by a 50-sound input method). Good. This is because, for example, it can be used to reject an operation input by the driver on the 50-sound input screen.

  The screen configuration changing means 11 is a means for changing the screen configuration of the screen to be displayed on the liquid crystal display 5. The “screen configuration” is the position, size, range, number, or type of menu items to be displayed on the screen. This refers to the size or color of characters to be displayed on the screen, the background color of the screen, an input method for inputting a predetermined item (50-sound input, list input, pull-down input, etc.) and the like. Further, the “menu item” refers to an image displayed on the liquid crystal display 5 and indicating that an operation input by the operator can be accepted.

  The screen configuration changing unit 11 refers to the response screen table of the screen configuration database 2 stored in the storage unit when the software button is pressed to change the display screen of the liquid crystal display 5. A screen ID corresponding to the combination of the button ID and the operator determined by the operator determination means 10 is acquired, and a response screen is displayed on the liquid crystal display 5 based on the image ID.

  The screen configuration changing unit 11 reads out registered data related to the background color, character size, software button arrangement, etc. of the response screen based on the acquired image ID from the storage unit, and constructs the response screen. When changing only the function corresponding to the software button (including changing the function name and icon displayed on the software button) without changing the shape, pattern, background color, etc., the screen is based on the image ID. The response screen may be constructed by referring to the display button table of the configuration database 2 and acquiring the button ID of the button to be arranged on the response screen.

  Next, a flow of processing in which the vehicle display system 100 changes the screen configuration of the response screen according to the operator will be described with reference to FIG.

  First, when the vehicle display system 100 detects that a predetermined software button has been operated and input on the touch panel 3 (step S1), the operator determination means 10 performs the operation input based on the output signal of the proximity sensor 4. Is determined by the driver (step S2).

  If it is determined that the operation input is made by the driver (YES in step S2), the screen configuration database 2 is referred to by the screen configuration changing means 11 and a response screen suitable for the operation input by the driver (hereinafter referred to as “driver screen”). Is displayed on the liquid crystal display 5 (step S3).

  The “driver screen” is a screen that enables a driver to shorten the time for operation input while the vehicle is traveling, and the number of button presses required to realize a desired function is a predetermined number of times (for example, 3 times). The number of menu items that can be selected, the input method (list input, pull-down input, pull-up input, etc.), the number of lists to be displayed, and the like are limited.

  On the other hand, if it is determined that the input is not an operation input by the driver (NO in step S2), the screen configuration database 2 is referred to by the screen configuration changing unit 11 and a response screen (hereinafter referred to as “ Is displayed on the liquid crystal display 5 (step S4).

  The “passenger screen” means more menu items or more complicated input methods (for example, 50-sound input or numeric keypad input) in addition to all functions realized on the driver screen. It is a screen that allows more detailed operation input.

  Note that the vehicle display system 100 permits operation input by a person other than the driver even when the driver screen is displayed once, and does not perform the operation input for a predetermined time. May automatically return to the screen before the driver screen is displayed. This is to facilitate the transition to the passenger screen.

  Further, the vehicle display system 100 may prohibit operation input by the driver for some or all menu items once the passenger screen is displayed. This is because menu items that the driver should not be allowed to input while driving are sometimes included. In this case, the vehicle display system 100 may tone down menu items for which operation input by the driver is prohibited (for example, gray display), and clearly notify the driver that operation input is not possible. Note that even when a predetermined menu item that has been toned down is toned down, an operation input by a person other than the driver is effective.

  When no operation input is performed for a predetermined time, the screen before the passenger screen is displayed may be automatically returned to. This is to facilitate the transition to the driver screen.

  With the above configuration, the vehicle display system 100 switches all response screens so that the operation input by the driver can be performed quickly and easily, thereby prohibiting all the operation inputs by the driver while the vehicle is traveling. Even so, it is possible to improve the convenience of the driver by permitting a predetermined operation input without forcing the vehicle to stop.

  In addition, the vehicle display system 100 allows a person other than the driver to input a more detailed and longer operation, while improving the convenience of the operator, while achieving the above-described effects. be able to.

  FIG. 4 shows the screen structure of the response screen according to the input subject of the operation input by the vehicle display system 100 when the destination setting button B1 which is an escutcheon button provided on the side of the liquid crystal display 5 is pressed. It is a figure which shows the example to change.

  FIG. 4A is a diagram showing a destination setting screen D1 that is displayed when the destination setting button B1 is pressed by a person other than the driver, and FIG. It is the figure which showed the destination setting screen D2 displayed when the place setting button B1 is pressed down.

  The destination setting screen D1 in FIG. 4 (a) allows the user to select a destination from a category such as a 50-sound button B3, “parking lot”, “park”, etc. Facility button B4 for transition to screen, address button B5 for transition to screen for selecting destination from address, telephone number button B6 for transition to screen for selecting destination from telephone number, destination from zip code It is composed of a zip code button B7 for transition to a screen to be selected and a history button B8 for transition to a screen for selecting a destination from a history of destinations selected in the past, to a screen on which a detailed operation input by a passenger can be made Encourage transitions.

  On the other hand, the destination setting screen D2 of FIG. 4B displays a list of a predetermined number (for example, the latest five) of destinations that have been selected in the past, and the driver displays the displayed list. The destination setting can be completed by pressing any of the buttons. In addition to the latest history, several lists may be displayed in descending order of setting frequency, or several lists may be displayed in order of distance from the current position. In this case, the driver need only perform a total of two operation inputs in order to set the destination.

  The destination setting screen D2 displays characters larger than the destination setting screen D1. This is so that the driver can grasp the screen contents with a glance. In addition to displaying characters large, an icon representing the characteristics of the destination may be displayed instead of the characters or together with the characters.

  FIG. 5 shows that when the information button B <b> 2 that is an escutcheon button provided on the side of the liquid crystal display 5 is pressed, the vehicle display system 100 changes the screen configuration of the response screen according to the input subject of the operation input. It is a figure which shows another example.

  FIG. 5A is a diagram showing an information screen D3-1 (one mode of the information screen D3) displayed when the information button B2 is pressed by a person other than the driver, and FIG. These are the figures which showed the information screen D3-2 (another aspect of the information screen D3) displayed when the information button B2 was pressed down by the driver | operator. The information screen D3 is a screen in which the size, arrangement, etc. of the software buttons are common except for the types of software buttons to be displayed.

  The information screen D3-1 in FIG. 5A is operated by a passenger such as an Internet button B9, a karaoke button B10, a radio button B11, a DVD (Digital Versatile Disc) button B12, a telephone button B13, and other information buttons B14.
