Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention comprises a display means disposed on an instrument panel of a vehicle and having a display section capable of defining a plurality of display areas. The present invention also relates to a vehicular multiple display device that displays warning information and the like as images in the display area in the form of characters and graphics, and particularly relates to a display configuration of a warning symbol that indicates the content of an abnormality when an abnormality occurs.

(Prior art) In recent years, instead of conventional mechanical instruments, display surfaces made of cathode ray tubes, EL elements, liquid crystals, etc. have been placed on vehicle instrument panels.
Vehicle display devices that display desired information as images on the display surface have been used and developed.

Such display devices constantly display information related to vehicle operation, such as vehicle speed, engine speed, distance traveled, coolant temperature, remaining fuel amount, and turbo boost pressure, as well as information such as brake fluid shortage. If an abnormality occurs such as insufficient charging, insufficient engine oil, insufficient cooling water, insufficient fuel, door ajar, or various lamps out, a predetermined warning symbol indicating the nature of the abnormality is displayed to alert you. There is.

By the way, as vehicles have become more multi-functional, the amount of driving information that must be displayed on the display screen has also increased, so the display space for warning symbols that indicate the details of abnormalities is limited, and the warning symbols are smaller than images of vehicle driving information. This tends to result in small displayed images.

In addition, as the number of display items that display driving information has increased, so too have the number of warning items.There are many types of warning symbols that indicate the occurrence of abnormalities, and even if an image of a warning symbol is displayed, the driver cannot see the display of the warning symbol. There were problems such as dropping the device and taking time to decipher the warning symbol.

Therefore, for example, in the display device disclosed in Japanese Patent Application Laid-Open No. 57-187618, the image of the vehicle running information and the image of the warning item are duplicated, and the image of the warning item is compared to the image of the vehicle running information. This image is made easier to read by making the image of the warning item darker depending on the level of urgency of the warning, but the image of the driving information and the image of the warning item are displayed twice. Therefore, there was a problem in terms of image visibility.

(Objective of the Invention) In view of the above circumstances, the present invention aims to improve the visibility of warning symbols when an abnormality occurs to make it easier to decipher the contents of the abnormality, and to prevent the conventional functions from being impaired after the contents of the abnormality are deciphered. An object of the present invention is to provide a multi-display device for a vehicle that can display the occurrence of an abnormality without any trouble.

(Structure of the Invention) As shown in FIG. 1, the present invention includes a display means disposed on an instrument panel of a vehicle having a display section capable of defining a plurality of display areas, and a predetermined display section in the display section. A control means for controlling the display means to generate a predetermined display regarding the running state of the vehicle in the display area. When an abnormality occurs, the control means interrupts and displays a warning symbol indicating the details of the abnormality that has occurred in the display area instead of the predetermined display, and reduces the warning symbol after a predetermined period of time has elapsed from the occurrence of the abnormality. The display device is characterized by comprising means for displaying the information in the predetermined display area together with the predetermined display.

(Effects of the Invention) With the above configuration, when an abnormality occurs, the warning symbol indicating the content of the abnormality can be displayed in a large size, so the visibility of the warning symbol is extremely good. The alarm display can be maintained without any loss in the conventional functions of the unit.

(Example) Examples of the present invention will be described in detail below with reference to the drawings.

FIG. 2 shows the driver's seat of an automobile equipped with the display unit of the multiple display device according to the present invention, where 20 is an instrument panel, 21 is a steering wheel, and 22 is an instrument panel! The 0 display screen 22, which is a display screen installed at 20, includes a fixed display area 23 where predetermined information is always displayed, and a multiple display area where a plurality of display screens, for example, three types, are selectively displayed by operating a changeover switch. It consists of area 24.

The three types of display contents displayed in this multiple display area 24 are, for example, "octopus-centered display" centered on tacho makeup;
These include the ``all item display'' and the ``safety monitor display,'' which display information that is almost the same as what is displayed on the instrument panel of a normal car. FIG. 3 shows the display screen 24a of "octopus center display".

Referring to FIG. 3, on the display screen 24a, an engine tachometer, or tachometer 25, and a torque sprint indicator 26, which indicates the state of power distribution to the front and rear wheels of a four-wheel drive system, are arranged. A pressure gauge 27, a water temperature gauge 28, and a fuel gauge 29 are arranged.

, FIG. 4 shows a block diagram of the electronic circuit of a multiple display device according to the invention. A controller 31 includes a microcomputer that calculates data input from each sensor and switch according to a control program, and performs processing to control the operation of the display 32. The terminal ■ of the controller 31 is a power supply terminal connected to the battery 34, and the terminals ■ to ■ are input terminals for data from each sensor that outputs data regarding fuel, turbocharging pressure, engine rotation, and vehicle speed. Terminal ■ is a terminal connected to the ignition switch. Terminals 1 to [phase] are input terminals connected to switches for respectively selecting the above-mentioned three types of display contents displayed in the multiple display area 24 of FIG. Furthermore, the terminal ■～[
[phase] is an input terminal connected to each sensing inch for warnings, such as insufficient brake fluid, poor charging, insufficient engine oil, abnormal exhaust pipe heat generation, insufficient cooling water, door ajar, tail lamp blown, stop lamp blown, and seat belt not installed. It is connected to a switch which is respectively closed in each case of installation. The output of the controller 33 is output from the controller 31 via the interface 35, and the signal ! 36
is provided to the interface 37 of the display 32 through the interface 37 of the display 32. The output of this interface 37 is given to a driver 38, and a display section 39 is driven.

In the above configuration, when the switch connected to the terminal ■ of the controller 31 in FIG. 4 is selected, the tacho center display screen 24a as shown in FIG. 3 is displayed on the multiple display area 24 in FIG. be done. On this display screen, the area 41 where the torque split indicator 26 indicating the state of power distribution to the front and rear wheels of the 4-wheel drive is displayed, and the warning symbol indicating the content of the abnormality that has occurred are shown in Figures 5A and 5B. The area to be displayed as shown. The warning display process by the control means is executed according to the flowchart of FIG.

In FIG. 6, this flow advances to step S1 every predetermined cycle, and inputs from each abnormality detection sensor are read. Next, in step S2, it is determined whether an abnormality has occurred. If YES, it is determined in step S3 whether or not it is a new warning, and if it is a new warning, a timer provided for each warning is started in step S4, and a warning indicating the details of the abnormality that has occurred is started in step S5. Read symbol. If the determination result in step S3 is No, the timer has already started, so the process moves directly to step S5. Next, the process proceeds to step S6, where it is determined whether a predetermined time (in seconds) has elapsed since the new warning occurred. If NO, the process advances to step S7, and the warning symbol is enlarged. Then, in step S8, the display area of the enlarged warning symbol is calculated, and in step S9, it is displayed in an interrupt manner. Therefore, instead of the torque spring 7) display meter 26, a warning symbol 42 indicating, for example, "brake fluid shortage" is displayed in the display area of the display screen 24, as shown in FIG. 5A.
is displayed in an enlarged state. Then, the flow returns to step S1 again, and similar processing is repeated to maintain this state of display. The process is repeated in this way, and when a predetermined time (seconds) has elapsed since the occurrence of a new warning, the determination result in step S6 becomes YES, and the process moves to step SIO, where the warning symbol is reduced, and step 311 The reduced warning symbol and the display area of the torque sprint indicator are calculated and displayed in an interrupt manner in step S12. Therefore, in the area 41 of the display screen 24, as shown in FIG. 5B,
A torque split indicator 26 and a reduced warning symbol 42' are displayed. If it is determined in step S2 that there is no abnormality, the process moves to step S12 to reset the timer, cancel the interrupt display in step 313, and return the screen to the state shown in FIG. 3, and the process proceeds to step 514. After that, the process returns to step Sl.

As is clear from the above description, according to the present invention, only the enlarged warning symbol 42 is displayed in the display area 41 when an abnormality occurs, so the visibility of the warning symbol 42 is extremely good, and the details of the abnormality are After reading, the alarm display can be continued without any loss in the conventional function of the display section.
