It is composed. The data area D2 includes alarm screen display data for displaying the alarm screen B, schematic diagram display data for displaying only the schematic diagram M in the alarm screen B, and the like.

Next, an example of an alarm process according to the present invention performed by the CPU 32 shown in FIG. 3 will be described with reference to a flowchart shown in FIG. Note that this alarm process is called up from the upper module every predetermined time when the CPU 32 is started by supplying power from a battery of the vehicle or the like.

When called from a higher-level module, an initial process is executed in step S 1, so that RA
An initial value is set in each area of M33, the first alarm item is set in the item pointer of the RAM 33, and then the process proceeds to step S2.

In step S2, the vehicle state detection processing is executed, whereby the vehicle state is detected based on the input signal from the sensor 40 corresponding to the alarm item indicated by the item pointer, and then the operation proceeds to step S3. For example, when the alarm item is the remaining fuel, the remaining fuel is detected as the vehicle state based on the fuel signal from the fuel sensor. Therefore, as is clear from the above description, the vehicle state detection processing corresponds to the vehicle state detection means described in the claims.

In step S3, it is determined whether the detected vehicle state is an alarm state. If it is determined that the state is the alarm state (Y in step S3), step S
Proceed to 4. Therefore, as is clear from the above explanation,
This determination processing corresponds to the determination means described in the claims.

At step 4, it is determined whether or not the alarm screen information D corresponding to the item pointer exists in the RAM buffer 34, thereby determining whether or not the alarm is being displayed. If it is determined that the alarm is being displayed (Y in step S4), the process proceeds to step S10. On the other hand, if it is determined that the warning is not being displayed (N in step S4),
Proceed to step S5.

In step S5, the alarm screen information extraction processing is executed, whereby the alarm screen information D having the type data corresponding to the item pointer is stored in the RAM 31 from the plurality of alarm screen information D stored in the ROM 31. Buffer 3
4, and then proceeds to step S6.

In step S6, the alarm screen display processing is executed, so that the alarm screen display data of the alarm screen information D in the RAM buffer 34 is output to the digital display 22 and a turn-off request is issued to the analog display 23. Is output, and furthermore, the display state data of the alarm screen information D is state-transitioned to "displaying the alarm screen", and then the process proceeds to step S7. By this process, only the alarm screen G displayed by the digital display 22 is displayed on the switching display unit 20.

In step S7, a predetermined time (for example, 5 seconds) is set by executing the timer start process.
When the timer expires, the timer which times out is started by designating the type data of the alarm screen information D corresponding to the item pointer, and then proceeds to step S8.

In step S8, it is determined whether or not the timer has timed out. If it is determined that the timer has not timed out (N in step S8), this determination process is repeated to wait for a predetermined time to elapse. On the other hand, when it is determined that the timer has timed out (Y in step S8), the process proceeds to step S9.

In step S9, the schematic diagram display process is executed, so that the schematic diagram display data of the alarm screen information B in the RAM buffer 34 corresponding to the type data designated by the timer is output to the digital display 22. , A turn-off release request is output to the analog display 23, and
The state transition of the display state data of the alarm screen information D is made to “during display of the schematic diagram”, and then the process proceeds to step S10. By this processing, the alarm screen B displayed on the switching display unit 22 shown in FIG. 4 is erased, and only the schematic diagram M of the schematic diagram area B1 of the erased alarm screen B is spur imposed on the lower left corner in the navigation information. The screen A is displayed on the switching display unit 22.

In the present embodiment, the schematic diagram M is spar-imposed at the lower left corner of the navigation information screen A. However, the present invention is not limited to this. Various embodiments can be adopted, such as spur imposing in an empty space.

In step S10, the next alarm item is set in the item pointer of the RAM 33 by executing the item increment processing, and then the process proceeds to step S11. Then, in step S11, it is determined based on the input data from the operation unit 50 whether or not a redisplay request has been received. If it is determined that a redisplay request has been received (Y in step S11), the process proceeds to step S12.

In step S12, the corresponding alarm screen information extraction processing is executed, whereby the alarm screen information D corresponding to the input redisplay request is stored in the plurality of alarm screen information D stored in the RAM buffer 34. The alarm screen display data of the alarm screen information D is output to the digital display 22, a turn-off request is output to the analog display 23, and the display state data of the alarm screen information D is “alarm”. The state is transited to “displaying screen”. Then, a timer that times out when a predetermined time (for example, 5 seconds) elapses is started by designating the type data of the alarm screen information D corresponding to the item pointer, and thereafter returns to step S8. Then, by repeating a series of processes from step S8, an alarm screen B corresponding to the input redisplay request is displayed on the switching display unit 20.

If it is determined in step S11 that a redisplay request has not been received (N in step S11),
Proceed to step S13. Then, in step S13, it is determined based on the item pointer in the RAM 33 whether or not the processing for all the alarm items has been completed. If it is determined that the processing has not been completed for all alarm items (Y in step S13), the processing is terminated and the process returns to the upper module.

If it is determined that the vehicle state detected in step S3 is not an alarm state (N in step S3), the process proceeds to step S14. Then, step S14
In the above, it is determined whether or not the alarm screen B or the schematic diagram is displayed on the digital display 22 based on the display state data of the alarm screen information D, thereby determining whether or not the alarm is displayed. When it is determined that no alarm is displayed (N in step S14), the process proceeds to step S10. On the other hand, when it is determined that an alarm is displayed (Y in step S14), the process proceeds to step S15.

In step S15, by executing the alarm screen erasing process, the type data of the alarm screen information D corresponding to the item pointer is designated, and the digital display 22 is displayed.
, An alarm display end request is output, and the alarm screen information D stored in the RAM buffer 34 is deleted. Then, the process proceeds to step S10. By this processing, the alarm screen B or the schematic diagram corresponding to the type data of the alarm screen information D is deleted from the switching display unit 20.

As described above, the CPU 32 displays the alarm screen B on the digital display 22 for a predetermined time, and displays only a schematic diagram when the predetermined time has elapsed. And when displaying the warning screen B,
By preventing the display of the analog display 23, the analog display is prevented from being visually recognized by the driver.
Therefore, the CPU 32 functions as a vehicle state detecting unit, a determining unit, a display control unit, a blocking unit, and a shift position detecting unit 32e described in the claims.

Next, an example of the operation (action) of the embodiment having the above-described configuration will be described with reference to the drawings. In addition,
In order to simplify the description, a case where the alarm item is the fuel remaining amount will be described.

In the vehicle display device 1, as shown in FIG. 2B, an analog meter is displayed on the fixed display unit 10, and the navigation information screen A is displayed on the switching display unit 20, and the sensor 40 is displayed. When it is determined that the remaining fuel amount (vehicle state) detected based on the signal input from the CPU is in an alarm state (Y in step S3), the alarm screen information D corresponding to the alarm item corresponding to the remaining fuel amount is stored in the ROM 31. Extracted from
Alarm screen B based on this alarm screen information D (see FIG. 5)
Is switched to the navigation information screen A and displayed on the switching display section 20 (steps S5 to S6).

When a predetermined time (for example, 5 seconds) elapses,
The navigation screen A (see FIG. 9) in which only the schematic diagram M of the schematic diagram area B1 of the alarm screen B is superimposed on the lower left corner is displayed on the alarm screen B.
Is displayed on the switching display section 20 (steps S7 to S9). Then, the schematic diagram M on the navigation information screen A is continuously displayed until it is determined that the vehicle state is not the alarm state thereafter (Y in step S14).

When the operation unit 30 outputs a redisplay request by the driver's operation while the schematic diagram M is displayed on the navigation information screen A, an alarm screen B corresponding to the redisplay request is displayed. Switch to navigation information screen A and switch display section 20
Is displayed (step S12). When the predetermined time has elapsed, the navigation information screen A (see FIG. 9) in which only the schematic diagram M is superimposed on the lower left corner is switched to the alarm screen B again and displayed on the switching display unit 20 (steps S7 to S).
9).

The above-described processing is performed for all of the alarm items shown in FIG. 6. If there are a plurality of alarm items to be displayed, the alarm screen B is switched and displayed at predetermined time intervals. Then, after all the alarm screens B are displayed, a plurality of schematic diagrams M of the displayed alarm screen B are superimposed and displayed on the navigation display screen A.

When an analog meter is displayed on the switching display section 20, the display of the analog meter is stopped and the alarm screen B is displayed. The schematic diagram M is superimposed and displayed as a virtual image.

As described above, when the detected vehicle state is the alarm state, the alarm screen B is superimposed and displayed as a virtual image on the switching display section (display area) 20 and a predetermined time (for example, 5 seconds) elapses. Then, the schematic diagram M of the alarm screen B
Since only the information is displayed, the warning screen can be enlarged to emphasize the display. In addition, since the alarm screen B highlighted is deleted after a predetermined time has elapsed,
The warning screen B does not obstruct the display target such as the tachometer.

Accordingly, the warning screen B can be displayed with good visibility, so that the driver can quickly recognize the warning state generated in the vehicle, and the safety of the vehicle can be improved.
