As for the other components, the same components as those of the center module of the first embodiment are designated by the same reference numerals, and description thereof is omitted.

As described above, the types of the multifunction devices can be increased or decreased or the functions can be adjusted without changing the functions of the center modules themselves in the first to third embodiments. In addition, the production cost can be reduced, and the composite device does not need an operation switch or the like, so that the cost of parts and the like can be reduced.

[Signal Input / Output Mode Between Center Module and Composite Device] Next, the signal input / output mode between the center module and the composite device will be described.

The center module ECU 120 includes a digital I / F circuit 126 or an analog I / F circuit 128.
The switch operation signal input through the device is distributed and output so as to correspond to the audio device 15, the navigation device 16, and the DIS device 17. The audio device 15, the navigation device 16, and the DIS device 17
Each unit is controlled according to a switch operation signal, and an image signal is output to the ECU 120. This image signal indicates that the unit has been controlled in accordance with the switch operation signal, and functions as a response signal to the switch operation signal.

When the image signal representing the control according to the switch operation signal is not returned, or when the image signal not matching the switch operation signal is returned,
Judge the failure of the output destination unit.

The ECU 120 receives image signals from the audio device 15, the navigation device 16, and the DIS device 17, and determines whether or not an image signal representing control according to the switch operation signal has been returned, or an image corresponding to the switch operation signal. After determining whether a signal has been returned, an image signal is output to the drawing circuit.

<Other Input / Output Modes> FIG. 56 is a diagram showing operations corresponding to other signal input / output modes between the center module and the multifunction peripheral.

As another signal input / output mode between the center module and the composite device, the ECU 120 of the center module may be used.
Distributes and outputs a switch operation signal input via the digital I / F circuit 126 or the analog I / F circuit 128 so as to correspond to the audio device 15, the navigation device 16, and the DIS device 17. An image signal representing control according to the operation signal is output to the drawing circuit, and the audio device 15, the navigation device 1
6. Control of the DIS device 17 and display control of the display may be performed substantially simultaneously.

In this case, the responsiveness of the control to the user's operation, for example, when setting the temperature of the air conditioner or setting the wind direction of the duct is improved.

<Data Transferred from Air Conditioner to Center Module> FIGS. 35A and 35B are diagrams showing display signal transfer data transferred from the air conditioner to the center module.

As shown in FIGS. 35A and 35B, display signal transfer data transferred from the air conditioner to the center module has a data length of 72 bits, and is 1 to 8 bits.
Up to bits are an instruction command area for designating display signal transfer contents, 9 to 66 bits are a display contents area representing display contents, and 67 to 72 bits are a parity area.

As shown in FIG. 36, the display signal transfer contents are designated by data CM0-CM7 in the command area, and subsequently, the display contents are designated by the display contents area. The data of 34 bits to 55 bits in the display content area is data representing display contents such as temperature display, for example, when the display is a dot matrix display, it is data representing numerical values. This is data representing the display content of the segment.

The center module recognizes that it is display signal transfer data in the command / command area, and executes the specified display processing in the subsequent display content area.

FIG. 37 is a flowchart showing the main control operation of the center module. FIG. 38 shows the meaning of the flags set in the center module.

As shown in FIG. 37, in step S2,
An initialization process is performed. In this initialization processing, a power-on reset / previous screen is set, flags are initialized, and an initial screen flag F4 is set at power-on or reset. For the setting of the previous screen, the screen displayed immediately before the ignition switch is turned off is stored in the memory, and the ignition switch is turned on (or power-on reset).
At that time, a process of reading the screen from the memory is performed.

In step S4, a failure detection / diagnosis process is executed. In this failure detection / diagnosis processing, a failure diagnosis is performed in the center module with another device (composite device), and if a serious failure has occurred, the flag F7 is set, and a moderate failure has occurred. In the case, the flag F6
Is set, and if a minor failure has occurred, the flag F5 is set.

In step S6, a process for detecting a switch operation is executed. This switch operation detection process detects whether an operation switch of the center module has been operated and a switch operation signal has been input, and sets a flag F3 when a switch operation has been performed.

In step S8, the arithmetic processing of the center module is executed. The arithmetic processing of the center module is performed, for example, when a clock is calculated or when display contents are changed, and a flag F1 is set when information is updated.

In step S10, a switch operation signal is output to another device.

In step S12, input processing of an image signal representing a control result from another device is executed, information of the other device (for example, air-conditioner air volume) is updated, and when the display content is changed, a flag F2 is set. Is done.

In step S14, the flag set in the center module is determined, and arbitration processing for screen display is executed.

At step S16, a drawing process on the display is executed based on the arbitration result at step S14.

In step S18, a screen setting process is executed. This screen setting process is a process in which the user can freely set the display on the display.

As shown in FIG. 38, the flag F7 is set when a serious failure occurs, reset when the failure is recovered,
The flag F6 is set when a medium level fault occurs and is reset when the fault recovers. The flag F5 is set when a minor fault occurs, reset when the fault recovers, the flag F4 is set when the power supply is initially turned on, and when another event occurs. Reset, the flag F3 is set when the switch is operated, and is reset when the switch is not operated for a predetermined time,
The flag F2 is set when the information of the other device is updated, and is reset when the arbitration process is completed. The flag F1 is set when the information of the center module is updated, and is reset when the arbitration process is completed. The flag F0 is a flag prepared in advance.

As shown in FIG. 39, in step S20, it is determined whether or not a failure has occurred. The determination of the occurrence of the failure is made based on whether any of the flags F5 to F7 is set. If a failure has occurred in step S20 (Yes in step S20), the process proceeds to step S40, and if no failure has occurred (step S20).
(No in 20), the process proceeds to step S22.

At step S22, it is determined whether or not the initial screen is displayed. This initial screen is determined based on whether the flag F4 is set.
When the initial screen is displayed in step S22 (Yes in step S22), the process proceeds to step S24, and FIG.
As shown in FIG. 1, the initial screen display process is executed with the display pattern shown in FIG. 46F, and the failure content is displayed in the area K (display example, see FIG. 50H). In step S22, when the FM multiplex switch is operated, the initial screen display process is executed in the display pattern shown in FIG. 46D as shown in FIG.

<Another Embodiment of Initial Screen Display Processing>
As another embodiment of the initial screen display processing, when the battery is connected or the memory of the center module is erased, the initial screen is set to a clock display or a clock and calendar display screen as shown in a display example E8 in FIG. The entire RGB display for diagnosing the failure can be performed.

When the ignition switch is turned on, the display screen when the previous ignition switch was turned off is used. When the previous display screen is the navigation screen, the navigation screen is not displayed. Can also be displayed.

If the initial screen is not displayed in step S22 (Yes in step S22), step S26
Then, it is determined whether or not a switch operation has been performed by the user. This switch operation is determined based on whether the flag F3 is set. Step S
If no switch operation has been performed in step 26 (step S
No in step S26), the process proceeds to step S34, and step S26

In the step S27, it is determined whether or not the switch operation is performed twice. If the switch operation has been performed twice in step S27 (Yes in step S27),
Proceeding to step S28, if the switch operation has not been performed twice in step S27 (No in step S27), proceed to step S34.

In step S28, display switching processing of the display pattern of the display screen is executed according to the type of switch according to FIG. 42, and screen display processing is executed with the display pattern shown in FIG. 46A or 46D.

In the step S30, it is determined whether or not a predetermined time (about 3 seconds) has elapsed on the screen displayed in the step S28. If the predetermined time has elapsed in step S30 (Yes in step S30), the process proceeds to step S32, and if the predetermined time has not elapsed in step S30 (step S3).
(No at 0), the process proceeds to step S36.

In step S32, as shown in FIG. 42, arbitration processing of the display screen is executed to
The screen display processing is executed with the display pattern shown in 6D.

At step S34, a display process described later is executed.

In the step S36, it is determined whether or not the information of the other device has been updated. In this information update determination, it is determined whether the flag F1 or F2 is set. If the information has not been updated in step S36 (No in step S36), the process returns to the start of the program, while if the information has been updated in step S36 (Yes in step S36), the process proceeds to step S38. Executes information update processing.

<At the time of failure occurrence> In the arbitration processing at the time of failure occurrence, the display area of the display screen is changed according to the rank of the failure so that the failure display does not disappear by the user's switch operation, and the user recognizes the failure. Then, if a predetermined switch is operated, the display area is reduced and displayed according to the rank of the failure, and if a plurality of failures occur simultaneously, the failure display is performed alternately.

When it is determined in step S20 that a failure has occurred (Yes in step S20), step S40
Proceed to.

In step S40, it is determined whether or not the occurred failure is a serious failure. The determination as to whether or not a serious failure is made is based on whether or not the flag F7 is set. If it is not a serious failure in step S40 (N in step S40)
o) In step S44, if it is a serious failure in step S40 (Yes in step S40), step S44

In step S42, as shown in FIG. 40, a failure screen display process is executed according to the display pattern shown in FIG. 46G, and the failure content is displayed in area L (display example, FIG. 5).
0J).

In step S44, it is determined whether or not the generated fault is a medium fault. The determination as to whether or not the failure is moderate is determined based on whether or not the flag F6 is set. If it is not a moderate failure in step S44 (No in step S44), it is determined that the failure is minor, and the process proceeds to step S48. If it is a moderate failure in step S44 (Yes in step S44), step S46 is performed.
Proceed to.

In step S46, as shown in FIG. 40, a failure screen display process is executed with the display pattern shown in FIG. 46H, and the failure content is displayed in area M (display example, FIG. 5).
0L).

In step S48, as shown in FIG. 40, a failure screen display process is executed with the display pattern shown in FIG. 46B or 46C, and the failure content is displayed in area D (display example, see FIG. 50N).

When a plurality of failures of the same degree occur in steps S44 and S46, the screen display is switched alternately at predetermined time intervals (for example, every three seconds).

As shown in FIG. 44, a serious failure is, for example, a brake failure or a failure that hinders traveling, and a moderate failure is, for example, a decrease in tire air pressure, a decrease in remaining gasoline amount, an ICC failure. , An airbag failure, a voltage abnormality, and the like, and the mild failure are, for example, a shortage of a washer fluid or a malfunction of a composite device.

<Display Processing> Next, the display processing operation of the center module shown in FIG. 39 will be described.

In this display processing, when a switch is operated while two or more types of display items are displayed, the operated items are emphasized by color change or enlarged display for a predetermined time to improve the visibility of the user. When the number of items that can be displayed simultaneously by the user is set and the number of display items equal to or greater than the number of displayable items occurs, the number of items that can be displayed is reduced to the maximum number of displayable items based on the priority order. Is performed according to a predetermined rule.

As a result, the display item on which the switch operation has been performed is highlighted to improve the visibility of the user.
In addition, the display area of the display screen can be customized by the user.

FIG. 45 is a flowchart showing the display processing operation of the center module.

As shown in FIG. 45, in step S60, it is determined whether any of the flags F3 to F7 has been set and the display pattern has been set. If the display pattern is not set in step S60 (No in step S60), the process proceeds to step S62, and if the display pattern is set (Yes in step S60),
Proceed to step S78.

At step S62, it is determined whether or not the screen of the navigation device is displayed. If the screen of the navigation device is not displayed in step S62 (No in step S62), the process proceeds to step S64. If the screen of the navigation device is displayed in step S62 (Yes in step S62), the process proceeds to step S72.

In step S64, it is determined whether the vehicle-mounted telephone is operating. If the in-vehicle phone is not operating in step S64 (No in step S64), the process proceeds to step S68, and if the in-vehicle phone is operating in step S64 (Yes in step S64), the process proceeds to step S66.

In step S66, the image is displayed in area J in the display pattern shown in FIG. 46E.

In step S70, a display area is determined. The display area is determined from the priority of the item to be displayed and the display priority in the determined display pattern, as shown in FIGS. 49A and 49B. However, when displaying items related to the air conditioner,
If the area A is empty in the display patterns P1 and P4, the area is set to the area A without considering the priority. This is because the item display relating to the air conditioner is always laid out at a fixed position to improve the visibility of the user.

In step S72, it is determined whether or not the vehicle-mounted telephone is operating. If the in-vehicle phone is not operating in step S72 (No in step S72), the process proceeds to step S76, and if the in-vehicle phone is operating in step S72 (Yes in step S72), the process proceeds to step S74.

In step S74, the screen of the navigation device and the screen of the vehicle-mounted telephone are alternately displayed in the area J in the display pattern shown in FIG. 46E.

In the step S76, the screen of the navigation device is displayed in the area J in the display pattern shown in FIG. 46E.

In step S78, it is determined whether or not there is any remaining display area. If there is no display area left in step S78 (No in step S78), the process returns to the start of the program. Step S78
If there is a display area left in step (Ye in step S78)
s), and proceed to step S80.

In the step S80, the flag F6 or F5
Is set or not. Step S8
If the flag F5 is set to 0, the process proceeds to step S8.
The process proceeds to step S4, and if the flag F6 is set, the process proceeds to step S82.

In step S82, since the fault is a medium fault, the display pattern shown in FIG.
The item with the highest priority other than the failure shown in 2 is displayed.

At step S84, it is determined whether or not there are two or more items to be displayed, since the failure is minor. If there are two or more other items to be displayed in step S84 (No in step S84), the process proceeds to step S86. If there are no more than two types of items to be displayed in step S84 (Yes in step S84), the process proceeds to step S88. move on.

In step S86, the item having the highest priority other than the failure shown in FIG. 49A is displayed in area A in the display pattern shown in FIG. 46B.

In step S88, items having the highest priority other than the failure shown in FIG. 49A are displayed in areas B and A in the display pattern shown in FIG. 46C.

The display screen is a diagram showing a procedure for switching the display screen when the number of display items increases from the current display screen as shown in FIG.

As described above, by performing the arbitration process on the display screen, even when a plurality of image signals are input from another multifunction device by a switch operation, the display necessary for the user can be appropriately adjusted according to the degree of failure and the priority order. Can be done.
