[Conventional technology]

Recently, research and development has been carried out on vehicle navigation devices that record map information on a CD-ROM or the like, read out the map information, display it on a display device along with the vehicle's current location, and guide the vehicle to a predetermined destination. . For example, when there is a designated facility such as a hotel, parking lot, gas station, or car dealership, such a conventional device displays the name of the facility along with the road near the location on a display device for the convenience of drivers. I am trying to provide it.

[Problem that the invention seeks to solve]

However, since conventional devices only display so-called map information including various facilities, etc., the TV tuner and AM installed in the vehicle are not used.

Even if there was a problem with electronic equipment such as the FM tuner, car stereo, or navigation device, it was not possible to notify the driver. Also, the vehicle may have a lack of oil, for example.
Although warning lamps are installed to warn the driver of abnormalities such as doors ajar and headlights turned off, these only have the function of notifying the driver of the result of the abnormality, and do not provide much information regarding the cause of the abnormality. Detailed information could not be provided to the operator.

[Effect]

The effect will now be explained. First, the basic operation when the navigation key 51 is operated will be explained. The processor 10 calculates and detects the current location of the vehicle from information from the direction sensor 7, speed sensor 8, GPS device 9, etc. In response to this information, the processor 6
- Read the map including the current location from ROM 1, and
to be memorized. Maps of a plurality of scales are recorded on the CD-ROMI, and maps of each scale including the current location are stored in the memory S. The processor 6 controls the controller 15 and causes data of a predetermined scale of the map stored in the memory 5 to be written in the memory 16 or 17. memory 16
．． 17, one side is the front side (the side where data is transferred to the memory 2o) and the other side is the back side (the side where the data is not transferred to the memory 20 and new data is written by the controller 15). The front side and the back side are alternately switched, and writing by the controller 15 is always performed on the back side that is not sending data to the memory 20.

The processor 6 further controls the controller 15 and stores the memory 16.1 in response to the current location signal from the processor 10.
Draw your own army mark on the front side of number 7.

In the map drawn in the memory 16.17 by the controller IS, data within a predetermined range centered on the own military mark is converted from parallel data to serial data by the parallel/serial conversion circuit 18, and the color signal is converted into color. The color signal is converted into a high gradation color signal by the palette register 19 and transferred to the memory 20. Memory 16.1
Which portion of the map drawn in 7 is to be transferred is designated by the processor 6 via the offset register 22 and address counter 23.

The processor 6 is also capable of drawing a photograph of, for example, an intersection recorded on the CD-ROMI directly into the memory 2o as an image. The image written in the memory 2o in this way is further transferred to the memory 21, and the image finally stored in the memory 21 is transferred to the D/A conversion circuit 26.2.
7.28 to be output and displayed on the display device 29.

By the way, in order to display the current location and map information on the display device 29 and perform a so-called navigation operation toward the destination, it is a prerequisite that a CD-ROMI is installed in the disk drive device. Therefore, in the present invention, when the ignition switch is turned on (power is turned on) when the vehicle is running and each electronic device is in a state where it can be energized, the abnormality is detected according to the flowchart shown in FIG. Perform processing for notification.

That is, first, the processor 6 diagnoses whether or not there is an abnormality in each device to be controlled. In this example, the display device! (
CRT) 29, CD-ROMI, CD player for music (CDP), air conditioner (air conditioner), processor (controller) 6, television (TV) tuner, FM tuner, GPSa device 9 devices. (parts not shown).

Of course, the device to be controlled may also be a device that detects a disconnection of a vehicle's headlamp, a lack of oil, etc. Therefore, in addition to map information, the CD-ROMI also records information for notifying the operator of the causes of abnormalities in these controlled devices mounted on the vehicle. When the diagnosis is completed, a block diagram of the device to be controlled is displayed on the display device 29, as shown in FIG. 4(a), for example. At this time, among the blocks, the block tt of the controlled device having an abnormality (trouble) is displayed in a different color from other blocks. In this embodiment, blocks of the CD-ROM are displayed in a different color from other blocks.

Since the blocks of the CD-ROM are now displayed in a different color from the others, the operator can know that there is an abnormality in the CD-ROM 1.

A touch sensor is arranged on the front surface of the screen of the display device 29, and when any block is touched with a finger or the like, it is detected. Then, it is determined whether an input has been made from the touch screen. Then, the process waits for a predetermined time (3 seconds in the embodiment), and if no input is made from the touch screen during that time, the process moves to the next step. Therefore, even if there is an abnormality in the CD ROMI, if there is no problem for the time being, for example because the user is heading to the destination without using the navigation device, the operator can simply leave it alone without touching the touch screen. .

When the operator touches the CD-ROM block on the touch screen, the processor 6 detects this.

As shown in FIG. 4(b), more detailed notification information regarding the cause of the abnormality is displayed as an image on the display device 29. In this image, the image of the CD-ROM disc is displayed differently from other images.

You will be notified that there is an error with the disc. At the same time, an announcement such as "No disc is loaded" is made by voice. These displays allow the operator to know the cause of the abnormality and to take countermeasures, such as installing a tisf before driving the vehicle.

Although the case where there is an abnormality in the CD-ROMI has been described above as an example, the same applies to cases where there is an abnormality in other devices to be controlled.
