It is a vehicle display device provided, and it can be predicted that the display by the display means stops.

  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 vehicular display device mainly includes an operation switch 1, a door opening / closing switch 2, a control unit 3, and a display unit 4. 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 display content displayed on the display means 4 based on an operator's pressing operation, and outputs a signal (input information) corresponding to the pressing operation to the control means 3. To do. For example, when the operation switch 1 is pressed once in the display state of the total accumulated travel distance display, the display content of the display unit 4 can be switched to the display of the section travel distance by the control of the control unit 3.

  The door opening / closing switch 2 is a switch for detecting whether or not the vehicle door is opened and closed, and can output a signal (input information) corresponding to the opened / closed state to the control means 3.

  As the control means 3, for example, a microcomputer can be applied, and input information from the operation switch 1 and the door opening / closing switch 2 or an ECU mounted on the vehicle separately via a CAN (Controller Area Network) communication cable (not shown). It is connected so that various vehicle information such as traveling speed can be input. The control means 3 can determine whether the ignition switch is on or off based on, for example, a signal from an ignition switch (start / stop switch). The control means 3 performs arithmetic processing according to these pieces of information and outputs a control signal for causing the display means 4 to perform a desired display.

  The control means 3 includes a CPU for performing arithmetic processing based on various information, a readable / rewritable RAM for temporarily storing arithmetic processing results in the CPU, and a ROM for storing control programs and control data. And an input / output interface connected by a bus for exchanging the various information, control signals, clock signals, latch signals, and the like.

  The display means 4 is a display based on a control signal from the control means 4 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 4 switches and displays the total accumulated travel distance display, the section travel distance display, the outside temperature of the vehicle, the fuel consumption, and the like by a gauge or a numerical value. In addition, the display means 4 can also express on the liquid crystal display panel a pointer that rotates in accordance with the control signal and an index such as a scale or a numerical value that is an instruction target of the pointer.

  Next, the processing procedure by the control means 3 when the ignition switch of the vehicle is off will be described with reference to FIG.

  The control means 3 first determines whether or not the ignition switch is off (step S1).

  When the ignition switch is off in the determination process of step S1, the control means 3 determines whether or not the ignition switch has been switched from on to off (step S2).

  When it is determined in step S2 that the ignition switch has been switched from on to off, the control means 3 initializes the counter (step S3). In this case, the control means 3 is set with a counter value corresponding to 60 seconds.

  Next, the control means 3 determines whether or not the counter is larger than a value corresponding to 0 seconds (step S4). In the process of step S2, if the ignition switch is not switched from on to off, that is, if the ignition remains off, the initial setting process of step S3 is not performed. The counter determination process in step S4 is performed.

  When the counter is larger than the value corresponding to 0 seconds in the determination process in step S4, that is, when 60 seconds have not elapsed since the initial setting process in step S3, the control means 3 decrements the counter (step S5). At this time, the control means 3 displays desired vehicle information (for example, total accumulated travel distance) on the display means 4 and numerically displays the remaining display time (remaining time) based on the counter.

  Next, the control means 3 determines whether the operation switch 1 is operated or whether the door is opened based on a signal (input information) from the operation switch 1 or the door opening / closing switch 2 ( In step S6), if any operation is performed, the process returns to the initial setting process in step S3. If no operation is performed, the process returns to the determination process in step S1.

  Further, in the determination process in step S4, the control means 3 displays the display on the display means 4 when the counter is not more than the value corresponding to 0 seconds, that is, when 60 seconds or more have elapsed from the initial setting process in step S3. Processing that is not performed is performed (step S7), and then determination processing of step S6 is performed.

  By repeating the above processing, the control means 3 displays the desired vehicle information for 60 seconds on the display means 4 after the ignition switch is operated from on to off, and until the display on the display means 4 ends. Can be displayed. Further, when there is input information from the operation switch 1 or the door opening / closing switch 2 in the state where the ignition switch is off, the remaining display time counting down from the initial setting of 60 seconds can be displayed together with the vehicle information.

  Such a vehicle display device includes a display unit 4 mounted on a vehicle for displaying vehicle information, and a control for controlling the display unit 4 to display the vehicle information for a predetermined time after the ignition switch of the vehicle is turned off. Means 3 for displaying the vehicle information after the ignition switch of the vehicle is turned off, and the remaining time until the display stops. It is displayed on the means 4.

  Therefore, since it is possible for the vehicle user to express whether or not the display unit 4 stops or when the display unit 4 stops, the display by the display unit 4 naturally does not give an uncomfortable feeling that the display stops. It becomes a display apparatus for vehicles which can know beforehand that will stop.

  The control means 3 controls the display means 4 to display the vehicle information for the predetermined time when the ignition switch is in an OFF state and there is predetermined input information, and until this display stops. Is displayed on the display means 4. Further, the control means 3 inputs information from either the operation switch 1 for switching the display content of the display means 4 or the door opening / closing switch 2 of the vehicle as the input information, and based on this input information By controlling the display means 4, when there is the input information when the ignition switch is off, the initially set counter and the vehicle information can be displayed again. Also in this case, the vehicle display device can know in advance that the display by the display means 4 is stopped.

  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, since the size of the display unit 4 is limited, the remaining display time by the display unit 4 may be displayed using a display portion that is not necessary when the ignition switch is off (for example, the instantaneous fuel consumption display portion). it can.
