Thus, the vehicle display device comprising the control means for controlling as described above is a convenient vehicle display device that can quickly display desired vehicle information.

  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 1, a control unit 2, and a display unit 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 means for switching the vehicle information displayed on the display means 3 based on an operator's pressing operation, and outputs a signal corresponding to the pressing operation to the control means 2. In this case, one operation switch 1 is provided at a position where it can be operated while visually recognizing the display means 3 on the instrument panel or the steering. For example, when the operation switch 1 is pressed once in the display state of the total accumulated travel distance display, the vehicle information on the display means 3 is changed to another vehicle information (for example, section travel distance) by the control by the control means 2. It is a switch for switching to the display.

  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 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 vehicle information item displayed on the display means 3 is used as display history information. Store. Further, the control means 2 is provided with a drive driver for driving the display means 3 and a pointer control part for controlling the analog display part.

  The display means 3 displays on the basis of 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 an organic EL panel can be applied. In this case, the display means 3 switches and displays the total accumulated travel distance, the section travel distance, the vehicle outside air temperature, the average fuel consumption value, the instantaneous fuel consumption value, 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 means 2 will be described with reference to FIGS.

  The control means 2 displays the total accumulated travel distance on the display means 3 (step S1), and a pressure determination process for determining whether or not the operation switch 1 has been pressed based on a signal from the operation switch 1 (step S2). I do. If it is determined by this determination that the operation switch 1 has been pressed, it is determined whether or not the operation switch 1 has been pressed for a predetermined time (for example, 2 seconds) from the press determination process (hereinafter referred to as long press). A long press determination process (step S3) for determination is performed.

  When it is determined from the determination result of the long press determination process that the control means 2 is not a long press (in the case of a pressing operation for less than a predetermined time), the next vehicle is displayed from the currently displayed vehicle information display. A screen switching process (step S4) for controlling the display means 3 is performed so that the display is switched to information (the next type of vehicle information prepared based on a predetermined order). For example, when the total accumulated travel distance (odo) is displayed, the control means 2 controls the display means 3 to switch to a screen displaying the section travel distance (trip) by this screen switching process.

  In addition, when the control unit 2 determines that a long press is made based on the determination result of the long press determination process, the vehicle information (this is displayed on the display unit 3) based on the display history information stored in the storage unit. Display means for selecting vehicle information (in this case, average fuel efficiency value) different from the total accumulated mileage), switching the screen from the displayed vehicle information display, and displaying the other vehicle information. 3 is controlled (step S5).

  Next, the control means 2 performs a re-pressing determination process (step S6) for determining whether or not the operation switch 1 has been operated again based on a signal from the operation switch 1. When the operation switch 1 is operated according to the determination result, the screen is switched from the display of the other vehicle information, and the vehicle information (for example, section travel distance, vehicle outside air temperature, etc.) different from the other vehicle information is displayed. The display means 3 is controlled so as to make it happen (step S7). In this case, the control means 2 controls the display means 3 so as to switch the display based on a predetermined order, and the screen is switched according to the number of re-pressing operations.

  Further, the control means 2, based on the signal from the operation switch 1, is the time after controlling the display means 3 so that the other vehicle information is displayed, or the pressing operation of the operation switch 1 is completed. A time determination process (step S8) is performed to measure the time from the time point and determine whether or not a certain time (for example, 60 seconds) has elapsed.

  The control means 2 stores the vehicle information being displayed on the display means 3 as display history information in the storage unit when the time is equal to or longer than the predetermined time based on the determination result of the time determination process (step S9). The display means 3 is controlled to return to the vehicle information (in this case, the screen of the total accumulated travel distance) displayed on the display means 3 during the long press determination process (step S1). The control unit 2 uses the display history information in the storage unit updated by the process of step S9 for the next process of step S5.

  By repeating the above processing, the control means 2 performs long-pressing operation of the operation switch 1 while the display means 3 is displaying the total accumulated travel distance. Vehicle information) can be displayed for a certain time by one operation.

  Such a display device for a vehicle is mounted on a vehicle and displays a plurality of vehicle information, an operation switch 1 that emits a signal in response to an operator's pressing operation, and a signal from the operation switch 1. And a control means 2 for controlling the display means 3 so as to switch and display the vehicle information. The control means 2 is configured such that the operation switch 1 is predetermined based on a signal from the operation switch 1. A long press determination process (step S3) for determining whether or not it has been operated for more than a time, and when the operation switch 1 has been operated for a predetermined time or more based on this determination result, the display means 3 displays The screen is switched from the vehicle information inside, and other vehicle information is displayed for a certain period of time.

  Therefore, even when there are many types of vehicle information that can be selectively displayed, the number of times that the driver operates the operation switch 1 until the desired vehicle information is displayed can be reduced. In addition, it is possible to quickly display desired vehicle information and to provide a convenient vehicle display device.

  Further, the control means 2 performs a re-pressing determination process for determining whether or not the operation switch 1 is operated again based on a signal from the operation switch 1 while displaying the other vehicle information. When the operation switch 1 is operated, the screen is switched from the other vehicle information, and the display means 3 is controlled to display the vehicle information different from the other vehicle information. It is possible to display the desired vehicle information quickly corresponding to the information, and to provide a convenient vehicle display device.

  Further, the control means 2 measures the time since the display means was controlled so that the other vehicle information is displayed, and when the predetermined time has passed or when the other vehicle information is displayed. The time after the pressing operation of the operation switch 1 is completed is measured based on the signal from the operation switch 1 and displayed on the display means 3 when the long press operation is performed when the predetermined time has elapsed. By controlling the display means 3 so as to display the vehicle information, the vehicle can be returned to the original display after a certain period of time without being operated by the operator. Display device.

  Further, the control unit 2 sets the vehicle information displayed on the display unit 3 when the predetermined time has elapsed as the other vehicle information that is switched when the long press operation is performed again. Since vehicle information that is highly likely to be used by the operator can be displayed preferentially, desired vehicle information can be displayed quickly and a convenient vehicle display device can be obtained.

  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, in the above-described embodiment, an example has been described in which a long press process is performed while displaying the total accumulated travel distance, but it is not necessary to initialize measurement values such as a vehicle outside air temperature and an instantaneous fuel consumption value. If it is vehicle information, it may substitute and the effect similar to the above-mentioned can be acquired. In addition, the time until the above-described fixed time elapses can be displayed together with the vehicle information.
