  The present invention includes a display means mounted on a vehicle for displaying vehicle information, an input means for switching and displaying vehicle information display items displayed by the display means, signals from the input means, and various sensors. And a control means for controlling the display means based on the information. The vehicle display apparatus can display a desired display item quickly and is convenient.

  Embodiments to which the present invention is applied will be described below with reference to the accompanying drawings.

  An example in which the vehicle display device of the present invention is applied to a vehicle instrument mounted on a vehicle will be described. As shown in FIG. 1, the vehicle display device mainly includes an operation switch (input means) 1, a control means 2, and a display means 3. In addition to the vehicle display device, the vehicle meter includes a so-called analog display unit that uses a pointer and a dial (not shown) for displaying the engine speed and the traveling speed.

  The operation switch 1 is an input unit for switching display items (display contents) displayed on the display unit 3 based on the pressing operation of the operator, and outputs a signal corresponding to the pressing operation to the control unit 2. . For example, when the operation switch 1 is pressed once in the display state of the total accumulated travel distance (odd) display, the display items of the display unit 3 are controlled by the control unit 2 based on display history information described later. It is a switch for switching to another display item (for example, display of section travel distance).

  For example, a microcomputer can be applied to the control means 2 and input information from the operation switch 1 or a traveling speed from an ECU separately mounted on the vehicle via a CAN (Controller Area Network) communication cable (not shown). It is connected so that various vehicle information can be input.

  Further, the control means 2 includes a CPU for performing arithmetic processing based on signals from the operation switch 1 and various information, a readable / rewritable RAM for temporarily storing arithmetic processing results in the CPU, a control program, and the like. And a storage unit composed of a ROM storing control data, and an input / output interface connected by bus for exchanging the various information, control signals, clock signals, latch signals, and the like. In addition to the RAM and ROM, a rewritable nonvolatile memory such as an EEPROM or a flash memory can be used as the storage unit. In this case, the control means 3 is provided with a driving driver for driving the display means 3 and a pointer control section for controlling the analog display section.

  The display means 3 is a display based on a control signal from the control means 2 in a vehicle instrument provided on the instrument panel of the vehicle. For example, a liquid crystal display panel or a driver for driving the liquid crystal display panel is provided. Applicable. In this case, the display means 3 switches and displays the total accumulated travel distance, the section travel distance, the outside temperature of the vehicle, the fuel consumption, and the like using gauges or numerical values. In addition, the display means 3 can also express on the liquid crystal display panel a pointer that rotates according to the control signal and an index such as a scale or a numerical value that is a target of the pointer.

  Hereinafter, processing by the control unit 2 will be described.

  The control unit 2 measures the display time or the number of selections for each display item displayed on the display unit 3 and performs history update processing for storing this in the storage unit as display history information. For example, as shown in FIG. 2, the display history information in the storage unit stores both the display time and the number of selections for each display item. The display time is obtained by integrating the display time of each display item, and the number of selections is obtained by counting the number of times displayed for a predetermined time (for example, 2 seconds) or more. Note that the display time may be added up after a predetermined time (for example, 2 seconds) has elapsed since the display item was selected (displayed) in consideration of the time during which the operator performs the selection operation. .

  Separately from the history update process described above, the control means 2 is based on an operation determination process for determining whether or not the operation switch 1 has been pressed based on a signal from the operation switch 1, and based on this determination result, When the operation switch 1 is pressed, a selection process for selecting a display item to be switched and displayed based on display history information in the storage unit is performed.

  In this selection process, the control means 2 selects the next display item (display item after display switching) in the descending order of either the display time stored in the storage unit or the number of selections. For example, when the display order is set in order from the longest display time shown in FIG. 2 while the vehicle outside air temperature is displayed (when the display time is set as the display frequency), the operation switch 1 is set based on the determination result. After determining that the pressing operation has been performed, a process of selecting the total accumulated travel distance with the longest display time as the next display item is performed. Further, when the operation switch 1 is operated within a predetermined time (for example, 30 seconds) from the determination process, the section travel distance A having the next display time after the total accumulated travel distance is selected as the next display item. Process as follows. If it is determined that the operation switch 1 has been pressed with the display item having the longest display time being displayed among the display items stored in the storage unit first, the display time is next long. Process to select display items.

  Further, the control means 2 outputs a control signal for prompting the next display item selected by the above selection process to be displayed to the display means 3 every time the selection treatment is performed.

  Such a vehicle display device includes a display unit 3 mounted on a vehicle for displaying vehicle information, an operation switch 1 for switching and displaying a display item of vehicle information displayed by the display unit 3, And a control unit 2 for controlling the display unit 3 based on signals and information from various sensors, wherein the control unit 2 stores display history information of the display items in a storage unit. At the same time, the display means 3 is controlled so that the display items are switched and displayed based on the display history information in the order of high display frequency.

  Accordingly, since items with a high display frequency can be displayed in order based on display history information stored in the storage unit, display items with a high use frequency (display frequency) of an operator can be displayed with a small number of operations. Since it can be provided, a desired display item can be displayed quickly, and the vehicle display device is convenient. In addition, since the display frequency is usually biased for each display item, the display order is in accordance with this bias, and therefore the probability of obtaining a desired display item before displaying a display item with a low display frequency is increased. The total number of operations can be reduced.

  Further, the control means 2 measures the display time for each display item, and stores these display times as display history information in the storage unit, whereby a display item with a long display time is displayed. Thus, according to the display history, a desired display item can be quickly displayed, and the vehicle display device is convenient.

  In the above-described embodiment, the description has been mainly given of the case where the display time is set as the display frequency. However, the control unit 2 determines whether or not the display item is displayed for a predetermined time or more and determines the predetermined time. The number of times displayed over time is measured and stored in the storage unit as display history information, and the display items are switched and displayed in accordance with the number of times so that the display frequency is in the descending order, as in the above-described embodiment. In addition, a desired display item can be quickly displayed and the vehicle display device can be conveniently provided.

  Further, the control means 2 initializes the display history information stored in the storage unit based on a predetermined operation (for example, a long press operation) of the operation switch 1 or other means (for example, an ignition switch). It is also possible to provide the most suitable display switching order in response to changes in the usage state of the operator or changes made by the operator.

The vehicle display device of the present invention has been described by way of example in the configuration of the embodiment described above, but the present invention is not limited to this, and the gist of the present invention is also achieved in other configurations. It goes without saying that various improvements and design changes can be made without departing from the scope. For example, after a certain time (for example, 5 minutes) has elapsed since the operation switch 1 was operated, the display is automatically switched to a predetermined display item (for example, total accumulated travel distance) or a display item having a high display frequency. You can also. Further, only the number of selections may be stored in the storage unit as the display history information.
