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

  As shown in FIG. 1, an in-vehicle instrument (vehicle instrument) A is incorporated and mounted in an instrument panel B provided on the front side of the driver's seat in the vehicle. The display of the meter A can be visually confirmed, and measurement information such as the traveling speed of the vehicle can be confirmed.

  As shown in FIGS. 2 and 3, the vehicle-mounted instrument A functions as a composite instrument, and includes a display 1, an input unit 2, and a control unit 3. These configurations are electrically connected via a circuit board, wiring, and the like, and are held in a case such as a synthetic resin.

  As shown in FIG. 2, the display unit 1 indicates a display panel (display unit) 11 that forms a display image by switching between transmission and non-transmission, and an indicator unit such as a scale or a numerical value by rotation of a motor as a driving source. The indicator type display unit 12 can be applied, and when the vehicle is powered on such as during normal driving, desired vehicle information such as the vehicle traveling speed and distance, the remaining capacity of the in-vehicle battery, an alarm, etc. It is an output means to display based on.

  As the display panel 11, a liquid crystal display panel provided with a backlight composed of a light source such as a light emitting diode can be applied. In this case, the display panel 11 generates and outputs a display screen according to the control signal from the control means 3, and the output luminance of the backlight can be changed based on the control signal from the control means 3. The circuit is configured.

  The input means 2 can be applied with a trip switch for switching and displaying the accumulated travel distance, section travel distance, etc. of the on-vehicle instrument. The input means 2 can also be applied as a dimming switch for setting the illumination brightness of the vehicle-mounted instrument including the display 1. The input unit 2 outputs an operation signal corresponding to the pressing operation of the vehicle user to the control unit 3. Further, the input means 2 can be used together with or replaced with the steering switch C1.

  As the control means 3, a microcomputer provided with a storage unit 31 used for storage of a predetermined program and various data, a storage area at the time of calculation, a CPU for performing arithmetic processing according to the predetermined program, an input / output interface and the like can be applied. Control signals for inputting operation signals from the input means 2 and vehicle information based on various sensors of the vehicle via a dedicated communication cable (multiplex communication line) and controlling the display 1 according to these signals Is generated and output. In this case, it is provided to be able to communicate with various electronic control units D, main switch unit E, and the like via the communication cable.

  The control means 3 starts the vehicle-mounted instrument when the main switch (start switch) of the main switch unit C mounted separately is turned on, and switches the display screen of the display panel 11 according to the operation of the input means 2. Among them, as shown in FIG. 4, an alarm state can be indicated.

  In the case of the display example shown in FIG. 4, a display area 110 a that displays an alarm symbol 111 that does not indicate specific alarm contents, an indicator 112 that indicates a running state, time information 113, and the like, and a display area 110 a below the display area 110 a. Further, detailed information (detailed display image) 114 of the alarm and a display area 110b indicating the gear position information 115 are displayed. Among these displays, particularly on the alarm symbol 111, a quantity image 111a indicating the quantity of the current alarm type is displayed in an overlapping manner.

  In this case, five alarms requiring attention are generated at the same time. One of the contents is text information 114a indicating “the door is open” shown in the lower display area 110b and an alarm mark 114b indicating the vehicle whose door is open. These images are displayed for a predetermined time (for example, 5 Every second), an image showing detailed information of other alarms is switched.

  Since the vehicle user can confirm the screen switching of the detailed contents after confirming the number of alarms generated by the quantity image 111a, it is not necessary to wait for the image switching of the detailed information 114 more than necessary. That is, it is possible to reduce the time for which the display is watched in order to confirm the content of the alarm that has occurred. It should be noted that the detailed information 114 can be switched to a display image of other vehicle information according to the priority and the running state.

  As shown in FIG. 5, the alarm symbol 111 has an outer shape imitating an isosceles triangle with the vertex 111b on the upper side and the base 111c on the lower side, which is substantially horizontal, on a yellow background! Marked symbols can be applied to indicate that an alarm condition has occurred. Among the display areas obtained by equally dividing the alarm symbol in the vertical and horizontal directions, a quantity image 111a is displayed in the upper right display area 111d.

  The quantity image 111a is displayed when a plurality of alarm states occur, and the quantity image 111a is not displayed when only one type of alarm state occurs. By displaying the quantity image 111a smaller than the warning symbol 111 on the upper right side of the warning symbol 111, an area overlapping with the above-described substantially triangular warning symbol 111 can be arranged small, and the display contents of the warning symbol 111 can be recognized. Does not cause a problem. In addition, in order to give smooth recognition in accordance with the general practice of visual recognition by moving the line of sight from left to right according to ergonomics, the quantity image 111a serving as additional information includes an alarm symbol. The display at the right position of the alarm symbol 111 is good with an image smaller than 111.

  Further, by superimposing a part of the alarm symbol 111 and the quantity image 111a, the alarm and the number can be associated with each other. In this case, the quantity image 111a displays a numerical value on a round background image 111e of a different color (for example, red) from the alarm symbol 111, and dares to make the quantity easier to see while increasing the contrast while making it different from the alarm symbol 111. doing.

  By displaying the alarm symbol 111 and the quantity image 111a, it is possible to determine not only the presence / absence of an alarm but also the time required to confirm the alarm content by the quantity (whether or not it can be confirmed by instantaneous visual recognition). It is useful as initial information for grasping. Also, these pieces of information can be expressed in a small display area without depending on the number of alarms that have occurred.

  Such a vehicle-mounted instrument A includes a display panel 11 that displays a plurality of vehicle information as images, and a control unit 3 that generates an image to be displayed on the display panel 11 based on the input of the vehicle information. 3 displays the alarm symbol 111 indicating that the alarm state is present and a quantity image 111a indicating the quantity of the alarm superimposed on the alarm symbol 111 when a plurality of items relating to the alarm are generated among the vehicle information. Display on the means.

  Therefore, even in a limited display area, the number of warnings can be recognized, and a highly recognizable warning display can be performed.

  The control means 3 displays a detailed image 114 indicating the content of the alarm for a predetermined time in a display area 110a different from the display area 110a indicating the alarm symbol 111 when a plurality of information relating to the alarm occurs among the vehicle information. By switching and displaying in turn every time, even if the alarm symbol 111 does not directly indicate the content of the alarm, it is possible to reliably call attention. In addition, display can be waited for display switching while checking the quantity of alarms, so that the display is highly recognizable.

  Although the vehicular instrument of the present invention has been described as an example in the configuration of the above-described embodiment, the present invention is not limited to this, and other configurations depart from the gist of the present invention. It goes without saying that various improvements and design changes can be made without departing from the scope. For example, as shown in FIG. 6, the quantity image 111a can be shown without providing the round background image shown in the above embodiment. In this case, the discriminability of the quantity can be improved by displaying in a color different from the display color of the alarm symbol 111.

  The vehicle meter according to the present invention can be applied as a display device such as a meter for a moving body such as an automobile or a motorcycle, and is particularly suitable as a display device for a vehicle that travels by consuming a plurality of types of energy.
