Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a vehicle navigation system that can display the position of a host vehicle that moves with the movement of the host vehicle on a map displayed on a display mounted on the vehicle.

[Related Art] Conventionally, various types of vehicle navigation systems have been developed and put into practical use. In this navigation system, there are two methods of detecting the position of the own vehicle, a method of detecting terrestrial magnetism and a method of using an artificial satellite. The former case will be described a little more. The current position is calculated by successively integrating the traveling direction per unit traveling distance using the vehicle orientation calculated from the difference between the terrestrial magnetism and the rotational speeds of the left and right wheels. Such a technique is called dead reckoning. The absolute azimuth is obtained by a geomagnetic sensor, and the travel distance and the difference between the left and right wheel rotational speeds are obtained by a wheel speed sensor.

When traveling in an area requiring a detailed map, such as a metropolitan area, the position of the own vehicle is detected by a map matching method. In other words, this map matching method utilizes the fact that a car travels on a road in principle, and estimates the vehicle position by comparing the travel locus calculated by the dead reckoning with the shape of the road,
It corrects the dead reckoning error.

And in such a vehicle navigation system,
For example, after setting the current position and the destination on the map displayed on the display with respect to the own vehicle position, the own vehicle position calculated by the above-described method is set on the map displayed on the display with the current position as an initial value. To be displayed.

As a result, when the vehicle moves, a mark (car mark) indicating the position of the vehicle moves on the map.

By the way, the map information is stored in a CD-ROM, and the map storage CD-ROM is set in a dedicated player and used.

[Problem to be Solved by the Invention] However, in the case of providing a player dedicated to the map storage CD-ROM such that the removal of the map storage CD-ROM cannot be easily performed as described above, the user wants to listen to the audio compact disc. In this case, two players for the audio compact disc are required, which is disadvantageous in terms of cost and arrangement space.

By the way, JP-A-1-277278 discloses a map CD-ROM.
In a player that can play a ROM (hereinafter simply referred to as a CD) and a music CD, when displaying the information of the map CD stored in the memory of the player during the playback of the music CD, the end of the song There is disclosed a technology in which the output is switched to the output of a map CD after waiting, and the map information is displayed, so that the map information is not interrupted suddenly in the middle of the music so that the driver does not feel uncomfortable.

However, in such a technique, if the eject button is pressed by mistake while using the map CD, the map CD is immediately ejected, so that the set data of the navigation which has been set is erased. There is a problem that.

Japanese Patent Application Laid-Open No. 63-288465 discloses a technique for preventing an error when replacing a disk cartridge of another person with one's own disk cartridge. If the eject operation is performed while the map CD is set in the player, the display for confirming the user's intention to eject is displayed on the display. It is possible that the map CD will be ejected. Further, in this technique, the means for indicating whether or not the disk cartridge can be replaced is only that the ready / non-ready lamp is turned off, and there is a possibility that data may be erased by an incorrect eject operation.

The present invention was created in such a situation, and enables a compact disc for map storage to be used in a common player with a compact disc for audio, and furthermore, an eject operation is performed when a compact disc for map storage is set. It is an object of the present invention to provide a vehicle navigation system that can be performed carefully.

[Means for Solving the Problems] For this reason, the vehicle navigation system of the present invention detects the position of the vehicle using the wheel speed sensor and the geomagnetic sensor, and moves with the movement of the vehicle. In a vehicle navigation system capable of displaying a position on a map displayed on a display mounted on a vehicle, a player that can use a compact disk for storing a map and a compact disk for audio that store a map to be displayed on the display, A compact disk eject operation unit provided in the player, and when the compact disk eject operation unit is operated while the map storage compact disk is loaded in the player, the display confirms the intention of the eject operation. And an eject operation confirmation means for displaying It is characterized by.

[Operation] In the vehicle navigation system of the present invention described above,
When the navigation is performed, a map is displayed on the display. Since the map is stored on the map storage compact disc, the map is used by the same player as the audio compact disc. If the compact disc eject operation unit with the player is operated while the map storage compact disc is loaded in the player, the eject operation confirmation means displays the eject operation confirmation display again.

Here, even when the user touches a display portion such as a nationwide map on the destination setting menu screen, the operation of the infrared touch switch 5-2 causes the nationwide map screen to appear first, and then a desired area (for example, Kanto area). ), A schematic map screen of the Kanto region appears, and if a desired area (prefecture unit; for example, Tokyo) is further selected, a schematic map of Tokyo appears. To display a more detailed map, the user may touch a desired area divided like a grid on the map. As a result, a detailed map of a desired area is displayed in the same manner as in each of the above modes. Of course, the same applies to the case where a desired map is displayed even when another part (facility, registered place, home display part) is touched.

Next, the map registration mode will be described. In the map registration mode, after setting the current location or the destination, the current location or the destination is set. That is, after steps A9 and A10 in FIG. 9, the mode is the map registration mode, and the map registration determination screen (steps A13 and A14 in FIG. 9 and step E1 in FIG. 13) is displayed. On this screen, "YES" and "NO" appear on the left and right of the display "Would you like to register the location?", And if you touch the "YES" part, the screen changes to the registration item selection screen. (Step E2).

This registration item selection screen includes home, office, villa,
There are indications of registered locations 1 to 3, and if the user touches a display portion corresponding to any of the above, registration with that name can be performed (step E3). If the return switch 5-10 is pressed, the screen returns to the map registration determination screen.

After step E3, it is determined in step E4 whether the current location has been set. If so, the mode shifts to the location mode (step E5). If not set, the map mode main menu appears. Move on (step
E6).

If you touch the “NO” part of the map registration judgment screen,
The processing after step E4 is performed.

Here, in the map registration mode, the current location registration unit 104 and the destination registration unit 105 mainly operate.

When the current location and the destination are registered in this way, the location can be registered immediately after the current location and the destination are set, and thereafter, the current location or the destination can be easily called based on the registration information. . Conventionally, there is a case where a map must be searched only for registration. However, compared to such a conventional one, the time and effort for registration can be greatly simplified.

Next, the "azimuth" or "vehicle"
(Step A7 in FIG. 9) by touching the display portion of the location mode will be described. In this case, as shown in step A7 in FIG. 9 and step F1 in FIG. 14, while the map mode main menu screen is being displayed, the display portion of either the “azimuth” or the “body” of the navigation portion is displayed. To select azimuth-centered navigation (map-fixed mode navigation with the north of the map pointing up) or car-centered navigation (map rotation mode navigation with the car head pointing up). As described above, when the user touches either the "azimuth" or "vehicle" display portion of the navigation portion, it is determined in step F2 whether or not the current position has been set. If so, the display changes to the location screen ( Step F3, Step A11 in FIG. 9). This location screen displays the car mark MK on the current location of the desired map.
"1" is displayed, and "Wide area" and "Details" are displayed at the bottom of the screen. When the "Wide area" and "Details" are touched, a reduced or enlarged map can be displayed as in the map mode. In addition, a distance display and a direction display to the destination are also performed.

Here, navigation is performed by a map matching method in a metropolitan area, and is performed by dead reckoning in other areas. However, the shape of a car mark is changed between a case using a map matching method and a case using dead reckoning. That is, the car mark MK1 in the case of the map matching method has a shape as shown in FIG. 8A, and the car mark MK2 in the case of the dead reckoning navigation has a shape as shown in FIG. 8B.

If the current location has not been set in step F2 in FIG. 14, use the switch F4 to set the current location.
Is displayed, and the map mode main menu (Step F4)
Return to

By the way, this navigation system can be started up by turning on an ignition switch as shown in FIG. 9 (step A2). In this case,
It is first determined whether or not the current mode is the map mode (step A3). If not, the system is set to the other system mode (step A15). If so, the CD check (step A3)
After 4), it is determined whether the mode was the location mode last time (step A6). If the ignition switch is turned off and it ends on the location screen,
Display the location screen of step A11 directly without going through the screen of the map mode main menu. Such an operation is performed as follows. For example, assume that the state immediately before the ignition switch is turned off is the location mode, that is, the display mode of the display when the navigation system is off is the navigation display by the navigation means 106. In such a state, when the ignition switch is turned off and the navigation system is turned off, the own vehicle position at that time is stored in the own vehicle position storage means 108 backed up by a battery. After that, when the ignition switch is turned on and the navigation system is turned on, that is, when the vehicle is started, the display selection control means 109 supplies the vehicle position stored in the vehicle position storage means 108 to the navigation means 106, The display mode of the display is a navigation display (location screen) by the navigation means 106.

In this way, if the state immediately before the ignition switch was turned off was the location screen, it can be started on the location screen at the next start-up, so it is not necessary to always start up from the map mode main menu, and usability is improved. Good.

Next, the map enlargement / reduction processing on the location screen will be described.

For example, assuming that a map with the widest area (for example, 1 / 400,000) is displayed for a certain area as in step G1 in FIG. 15, in this case, there is no map with a wider area. The indication "Wide area" is turned off.
Therefore, the operator can touch only the display “Details”. This allows the user to know that the currently displayed map is the widest map without knowing that it is the widest map, and does not make any mistake in the map magnification change operation.

If the "details" display portion is touched in step G1 of FIG. 15, it is determined in step G2 of FIG. 15 whether there is a map that is two steps more detailed than the current one. This is because there are up to four types of prepared maps having different reduced scales. That is, in urban areas, 1/400000, 1/100000, 1/2500
0,1 / 12500, and in other areas, 1/400000,
It is two kinds of 1/100000.

If YES in step G2, a display of "wide area" appears next to the "details" display portion of the screen as in step G3. That is, 1/100000, 1/250 of metropolitan area
While the map of 00 is being displayed, "Details" and "Wide area" are displayed on the screen. So, in this case,
You can get a more detailed map by touching "Details" or a wider map by touching "Wide area". Then, when you touch "Details", again in step G2,
While it is determined whether there is a two-step detailed map from the present, if you touch "wide area", in step G4,
It is determined whether there is a map with a wide area. In the case of YES in this step G4, “details”,
A map screen having both displays of “wide area” appears. In the case of NO, a screen in which the display of “wide area” disappears from the screen as in step G1.

In addition, in the case of NO in step G2, since the most detailed map for a certain area is displayed in step G5, in this case, there is no more detailed map, so "details" is displayed from the screen Disappears. Therefore,
The operator can only touch the indication "wide area". This allows the user to know that the currently displayed map is the most detailed map without knowing that it is the most detailed map, and does not make a mistake in the map magnification change operation.

Therefore, if the current display map is that of a metropolitan area, as shown in steps H1 to H4 in FIG. 16, different maps with four-stage magnification for the same area can be displayed. In this case, , 1/400000 (the widest area map), only the display “Details” is displayed, and the display “Wide area” is not displayed (step H1). 1 / 100000,1
When a map of / 25000 is displayed, "Details" appears on the screen.
And "Wide area" are displayed, so you can touch "Details" to get a more detailed map, or you can touch "Wide area" to get a wider map at "Steps H2, H3." When displaying a map of 1/12500 (the most detailed map), only the display of "enlarged" is displayed, and the display of "detailed" is not displayed (step H4).

In addition, if the current display map is outside the metropolitan area, as shown in steps I1 and I2 in FIG. 17, it is possible to display maps of the same area with two-stage magnification different from each other. When displaying the map of 1/400000 (the widest area map), only the display of "Details" is displayed, and the display of "Wide area" does not appear (step I1). At the time of display, only the display of “enlarge” appears, and the display of “details” does not appear (step
I2).

During the scale change processing for changing the scale of the map, as shown in FIG. 18, a message "Please wait" appears at the bottom, leaving the car marks MK1 and MK2.

Here, the display deletion selection of the "wide area" and "detail" display at the time of the enlargement / reduction processing on the location screen is performed by the operation mark display deletion selection means 101A of the map display means 101 acting.

In addition, the display deletion selection of the "wide area" / "detail" display at the time of the map enlargement / reduction processing is the same as when performing the display map enlargement / reduction processing in the map display mode, the current location setting mode, and the destination setting mode. Applied to For example, taking the metropolitan area in the map display mode as an example, the widest area map (1/40
When displaying “0000 map”, only the display “Details” appears, the display “Wide area” does not appear, and 1 / 100000,1
When a map of / 25000 is displayed, "Details" appears on the screen.
And "Wide area" are displayed and the most detailed map (1/12500
At the time of display of the map), only the display of “enlarge” appears, and the display of “details” does not.

By the way, when the CD-ROM 81 for a map is loaded in the CD player 8, when the compact disk eject operation unit 2-4 with the CD player 8 is operated, the display 5--
1 is displayed again to confirm the intention of the eject operation. That is, the map CD-ROM 81
Is loaded in the CD player 8, and the CD player 8
By operating the compact disk eject operation unit 2-4 with a key, a CD-ROM eject including a display "Cancel map mode" and a display "YES" or "NO" as shown in step J2 of FIG. A confirmation screen appears. As a result, it is known that the CD-ROM 81 is set. If the user operates the CD-ROM 81 by mistake, "NO" may be touched. This returns to the original screen (step J1). If the required time has elapsed without pressing the return switch 5-10 or doing anything, the screen returns to the original screen (step J).
1).

If the user touches "YES", a map mode end screen "Navigation is completed" is displayed (step J3).

Thereafter, it is determined whether or not the interrupt mode is a map. If NO, the process returns to step J1. If YES, the map mode end screen is maintained (step
J5). After that, the CD-ROM 81 is ejected.

When the compact disc eject operation unit 2-4 with the CD player 8 is operated while the map CD-ROM 81 is loaded in the CD player 8, the eject operation is confirmed again by the operation of the eject operation confirmation means 110. Since the display for confirming the operation is made, the following effects are obtained. That is, during navigation, the map CD-RO
When the M81 is ejected, the navigation is interrupted, and if it is interrupted like this, it is necessary to set the current location and destination again, which is very time-consuming.
If the display for confirming the eject operation is performed as in the present embodiment, the erroneous operation as described above can be sufficiently prevented.

It is also conceivable to provide a player dedicated to the map CD-ROM that makes it difficult to remove the map CD-ROM. However, this requires two players for the audio CD, and thus costs and costs are reduced. It is disadvantageous in terms of installation space.

(B) Sound mode and TV mode The sound mode is used to combine sound with a dedicated full audio unit 2 with a built-in CD player 8 (used for both music and maps), a tape deck, and an FM / AM tuner (radio receiver). This is a mode in which a scene can be set. FIG. 21 shows an example of a screen display in this sound mode. In order to output the image in the sound mode, the sound switch 5-4 of the monitor unit 5 may be pressed. In this sound mode, selection of the optimum volume balance according to the seating position (driver-front-rear-all seats) (refer to the "position" display portion in FIG. 21), selection and display of a feeling of sound spread (cabin- Studio-Hall-Stadium) (See the "Field" display in Fig. 21),
In addition to selecting and displaying frequency characteristics (classic, vocal, jazz, and rock) (see the “Sound” display part in FIG. 21), it also has an equalizer function that can set and display the desired frequency characteristics.

The TV mode is a mode for receiving and displaying a television broadcast.
What is necessary is just to press the television switch 5-5 of the monitor unit 5. Further, in this embodiment, an automatic memory capable of receiving audio multiplexing and stereo broadcasting and automatically storing, for example, up to 10 broadcasting stations having good radio wave conditions is provided. The television receiver can receive both VHF and UHF signals, and can also reproduce video by connecting a video deck or a video camera to the video connection adapter 3-1. The operation in the TV mode can also be performed by the TV remote controller 51.

By the way, for the reception of the radio broadcast (AM / FM broadcast) and the television broadcast, the motor antenna 91, shown in FIG.
A rear window glass antenna 92 is used. Here, the rear window glass antenna 92 has an antenna element 92a for radio and the antenna elements 92b to 92d for television, but a motor antenna 91 which can be extended and retracted by a motor is used for radio broadcasting (AM / FM broadcasting) and television. Used for both broadcasting. As described above, since the motor antenna 91 is used for both radio and television, the length of the motor antenna 91 is also controlled to an optimum length according to the reception frequency. A control block diagram for this is shown in FIG.
The result is as shown in FIG. That is, in FIG. 20 (a), reference numeral 201 denotes a reception frequency discriminator, and the reception frequency discriminator 201 has a current reception mode of AM / FM radio mode, TV VH
FL (low) mode, TV VHF-H (high) mode, TV-U
AM / FM, which determines which mode is HF
If it is determined that the mode is the radio mode or the TV VHF-L (low) mode, the antenna full extension signal FULL is output while the TV VHF
When it is determined that the mode is the -H (high) mode or the TV-UHF mode, the antenna half-extended signal HALF is output.

Reference numeral 202 denotes a motor control unit. In response to the antenna full extension signal FULL or the antenna half extension signal HALF from the reception frequency discriminator 201, the motor control unit 202 transmits a signal to that effect to extend and retract the antenna 91 by a motor ( (Motor) 91A.

When the motor control unit 202 receives the full antenna expansion signal FULL from the reception frequency discriminator 201, the motor 91A is driven so that the antenna 91 is in the full extension state, while the reception frequency discriminator 201 transmits the half antenna signal. Upon receiving the extension signal HALF, the motor 91A is driven, so that the antenna 91 is in a semi-extended state.

At the time of radio reception, the antenna full extension signal FULL is output,
At the time of television reception, it is also possible to output a half-stretched antenna signal HALF.

In addition, as shown in FIG.
As 201, it is also possible to use a device that receives the reception frequency information and outputs continuous antenna length information determined according to the reception frequency. In this case, instead of adjusting the length of the antenna 91 in two steps, The antenna can be adjusted steplessly, and the antenna length can be finely adjusted.

In this way, the reception frequency discriminator 201 and the motor control unit 202 constitute an antenna length control means for controlling the length of the antenna 91 so that the antenna length is determined according to the reception frequency.

(C) Vehicle information mode The vehicle information mode has the following display function. To display an image in the vehicle information mode, the vehicle switch 5-7 of the monitor unit 5 may be pressed.

(1) The traveling direction of the car is displayed as either the fixed direction or the fixed body (see FIG. 25 (a)).

(2) The travelable distance after the tank is full is displayed [see FIG. 25 (a)].

(3) When a control abnormality occurs in the traction controller or the anti-skid brake controller, a warning is displayed.

(4) A memo can be entered and displayed as personal information [25th
See FIGS. (B) and (c)].

(5) The contents of the memo input on the date are automatically displayed on the corresponding day (see FIG. 25 (d)).

 Each of the above functions will be described.

First, when the vehicle switch 5-7 of the monitor unit 5 is pressed, a display screen basically appears as shown in Fig. 25 (a). The distance is displayed, and in the middle part, either the traveling direction (arrow) fixed to the azimuth or the traveling direction (arrow) fixed to the vehicle body is displayed, and “memo” and “display” are displayed below. In addition, switching of the screen of the traveling direction (arrow) of the fixed direction or the traveling direction (arrow) of the vehicle body is
This is done by touching the display unit.

Next, a description will be given of a display of a travelable distance after the tank is full. In this case, when refueling at a gas station,
When the "full tank" display portion is touched, the internal travelable distance calculation device automatically calculates and displays the subsequent travelable distance.

If a block diagram of such a travelable distance calculation device is shown,
The results are as shown in FIGS. In these FIGS. 22 and 23,
Reference numeral 300 denotes a travelable distance calculation CPU (computer). The travelable distance calculation CPU 300 includes a fuel consumption calculation unit 301, a travel distance calculation unit 302, a remaining fuel calculation unit 303, a fuel consumption calculation unit 306, and a travelable distance calculation unit. It has 307 functions.

Here, the fuel consumption calculation unit 301 receives the injector pulse data from the injector control signal supply unit (ECI) 15 for the injector IJ, and calculates the fuel consumption based on the injector pulse data. A fuel consumption calculating means for calculating fuel consumption from information on the amount of fuel supplied to the internal combustion engine is configured.

The traveling distance calculation unit 302 receives the vehicle speed pulse from the vehicle speed sensor 14 and calculates the traveling distance based on the vehicle speed pulse.

The remaining fuel calculation unit 303 calculates how much fuel remains in the fuel tank, that is, calculates the consumed fuel calculation unit 301 from the amount of fuel that is full (full state) of the fuel tank.
The remaining fuel is calculated by subtracting the fuel consumption calculated in step (3).
Are a full tank switch 304 as a manual type initial value setting switch (in this embodiment, an infrared switch which is turned on when a “full tank” display portion is touched), and a fuel amount detecting means for detecting a fuel amount in the fuel tank. Each signal from the fuel gauge 16 is input. That is, when the full fuel switch 16 is depressed, the remaining fuel calculation unit 303 determines whether the remaining fuel calculation unit 303 has the initial fuel amount if the fuel amount detected by the fuel gauge 16 corresponds to the full fuel amount. The full fuel amount is set as the value, but if the fuel amount detected by the fuel gauge 16 does not correspond to the full fuel amount, the full fuel amount is set as the initial value of the remaining fuel calculation unit 303. It also has a function of an initial value setting means 303A for prohibiting the operation.

That is, the calculation flow in the remaining fuel calculation unit 303 will be described with reference to FIG. 27. First, in step K1, by touching the “full” display section of the vehicle information mode display screen, the full tank switch 304 is turned on. When done, the fuel gauge 16
It is determined whether the output resistance is equivalent to a full tank value (for example, 6Ω). If the output resistance of the fuel gauge 16 is equal to or greater than the full tank equivalent value, in step K3, the full tank is accepted, the full fuel amount is set as the initial value of the remaining fuel calculation unit 303, and then the remaining fuel calculation is performed. Is started (step K4), if the output resistance of the fuel gauge 16 is less than the full tank equivalent value, the full tank input is canceled in step K5, and the remaining fuel calculation unit 303 sets the full fuel as the initial value. Prohibits setting the amount.

Accordingly, even if the full switch 304 is accidentally touched when the tank is not full, if the tank is not actually full, the full tank input is cancelled. Inaccurate remaining fuel can be reliably prevented from being calculated.

The fuel efficiency calculation unit 306 calculates the fuel efficiency (km / l) by dividing the travel distance (km) calculated by the travel distance calculation unit 302 by the fuel consumption (l) calculated by the fuel consumption calculation unit 301. Is what you do.

The mileage calculating unit 307 calculates the mileage (km) by multiplying the fuel efficiency (km / l) calculated by the fuel efficiency calculating unit 304 by the remaining fuel (l) calculated by the remaining fuel calculating unit 303. Things.

Then, the output of the travelable distance calculation unit 307 is displayed on the display 5-1. According to the display example of FIG. 25 (a), it can be seen that the possible travel distance is 520 km.

In this case, as described above, even if the user accidentally touches the full tank switch 304 when the tank is not full, if the tank is not actually full, the full tank input is canceled.
Incorrect remaining fuel can be reliably prevented from being calculated due to an erroneous operation of the full tank switch 304 when the tank is clearly not full.As a result, the mileage can always be calculated accurately. , It is possible to always display an accurate travelable distance.

In FIG. 23, reference numeral 14 'denotes a speedometer from which a vehicle speed pulse from a vehicle speed sensor 14 is supplied.

Reference numeral 16 'denotes a fuel gauge, and the fuel gauge 16'
Is connected to the fuel gauge 16.

Reference numeral 308 denotes a display operation unit.
It functions as an interface for inputting a full tank switch and displaying a mileage, and in this embodiment, a part of the monitor unit 5 corresponds thereto.

Next, when a control abnormality occurs in the traction controller or the anti-skid brake controller, a warning display function is provided. Since this function is similar to a normal diagnosis function (failure display function), its description is omitted. I do.

Further, a description will be given of a schedule display in which the input and display of a memo as personal information (memo display) and the content of a memo input on a date are automatically displayed on the corresponding day.

First, FIG. 24 shows a control block diagram for displaying the memo and the schedule. This 24th
In the figure, reference numeral 401 denotes memo information storage means, which stores memo information input through the infrared touch switch 5-2.

Reference numeral 402 denotes a memo information display control unit. The memo information display control unit 402 displays a memo operation mark (display “memo”) on the display 5-1 and performs an operation of touching the memo operation mark to display a memo screen. To input memo information including calendar information to the memo information storage means 401 and display memo information (including calendar information) stored in the memo information storage means 401 on a memo screen. Further, the memo information display control means 402 is provided with a memo operation mark display erasing means 402A for erasing the display of the memo operation mark when the vehicle is running.

Reference numeral 403 denotes a calendar storage unit.
Stores calendar information in, for example, the Christian era.
Reference numeral 404 denotes clock means for counting time.

Reference numeral 405 denotes calendar information display control means. The calendar information display control means 405 can extract the corresponding calendar information from the calendar storage means 403 based on the time information counted by the clock means 404 and display it on the display 5-1. Things.

Reference numeral 406 denotes a calendar linked memo information display control unit. When the calendar linked memo information display control unit 405 displays the calendar information by the calendar information display control unit 405,
When the calendar information to be displayed matches the calendar information in the memo information, the memo information is displayed together with the calendar information.

Reference numeral 407 denotes a memo main control unit.
Are the respective units 401 to 406 or the monitor unit 5
(The monitor unit 5 passes through the graphic generator 6).

Hereinafter, the operation procedure for displaying the memo and the schedule will be described with reference to a display example. The vehicle information mode screen shown in FIG. 25 (a) is displayed by pressing the vehicle switch 5-7. Then, touch the "memo" display area. Then, a memo display screen as shown in FIG. 25 (b) is displayed. Further, this memo display screen has a total of eight areas, and each area has a month area on the left and a memo area on the right. The display changes to a memo input screen as shown in FIG. For example, three memo input screens such as a numeric screen, an English character screen, and a pictorial symbol screen are prepared. At the top of each screen, a memo screen to be entered from now on is displayed. Information) and memo information can be entered.] Is displayed. Then, the desired self-hardening is input while appropriately switching the memo input screen. Note that memo input is performed using the cursor switch 5-11 and the touch switch 5-2, and is registered by pressing the set switch 5-12. The switching of the memo input screen is performed by touching a “page” in the screen.
Here, a maximum of eight memo input areas are prepared as described above.

After inputting the memo in this way, by touching the "memo" display portion in FIG. 25 (a), the calendar information indicating what month and what day is scheduled as shown in FIG. 25 (b) Can be displayed on the display 5-1. Such an operation function,
Mainly due to the action of the memo information display control means 402.

By the way, the above “memo” display portion is displayed as shown in FIG. 25 (a) only when the vehicle is stopped, but when the vehicle is running,
26 As shown in Figure 26, it is erased and not displayed. Such an operation function is mainly performed by the memo operation mark display means 402A.
By the action of

In this way, it is possible to make it impossible to perform a transition operation to a screen that is not preferable to operate while the vehicle is running, and this greatly contributes to safe driving.

While the vehicle is running, the “display” display may be turned off together with the “memo” display.

Even when the engine is stopped by turning off the ignition switch, the above memo contents are stored in the memo information storage means.
When the ignition switch is turned on the next time the engine is started, as shown in FIG. 25 (d), a calendar indicating that the current day is a month and a day, and a schedule for the day is required. The time is displayed. If the memo content for that day extends over a plurality of memory areas, the memo content last entered is displayed.

The schedule display function is mainly performed by the calendar information display control means 405, the calendar link memo information display control means.
406.

Here, the flow for this schedule display is as shown in FIG. 28.First, in step L1, when the ignition switch is turned on, in step L2, it is determined whether there is a memo corresponding to the current date. Is determined, and if there is a match, the memo content is displayed (step
L3).

Then, when the required time has elapsed, the screen immediately before the engine stops (last screen) is displayed (step L4).

If there is no corresponding memo screen, the screen is changed to the last screen (step L4).

In this way, if the date entered in the memo matches the current date, the memo content of the day is automatically displayed when the ignition is turned on, so that you can see the schedule of the day without recalling it, It is very convenient.

In the above example, the display is performed when the date matches the current date. However, the date is displayed every day during the applicable month (for example, every day during April), or on the corresponding month (for example, on the 10th of every month).
Can also be displayed.

In the above embodiment, the integrated information system having the multi-modes of the map mode, the sound mode, the television mode, and the vehicle information mode has been described. However, the present invention can be applied to a system having only the navigation system. Not even.

[Effects of the Invention] As described in detail above, according to the vehicle navigation system of the present invention, the position of the own vehicle is detected using the wheel speed sensor and the geomagnetic sensor, and the vehicle moves with the movement of the own vehicle. In a vehicle navigation system capable of displaying the position of the vehicle on a map displayed on a display mounted on the vehicle,
A player capable of using a compact disk for map storage and a compact disk for audio for storing a map to be displayed on the display, a compact disk eject operation unit provided in the player, and the compact disk for map storage provided in the player When the compact disk eject operation section is operated while the compact disk is being loaded, an eject operation confirmation means is provided on the display for confirming the intention of the eject operation. If the compact disc eject operation unit with the player is operated while the disc is loaded in the player, the eject operation confirmation means displays again a message for confirming the intention of the eject operation. No effect Point is obtained.

That is, according to the vehicle navigation system of the present invention, even if the eject operation is performed by mistake while using the map storage compact disc, the confirmation of the intention of the eject operation is displayed on the display. There is an advantage that the erasure of the navigation setting data due to can be prevented. On the other hand, in the past, if the compact disc for map storage was accidentally ejected during navigation, the navigation function was interrupted, and the current location setting and the destination setting had to be performed again, which was extremely troublesome. By performing the display for confirming the intention of the eject operation as in the in-vehicle map display system, the erasure of the setting data as described above can be sufficiently prevented.

In addition, if a player dedicated to the compact disk for map storage is provided so that it is not easy to remove the compact disk for map storage, two players for the compact disk for audio are required, so that cost and layout space are reduced. However, the in-vehicle map display system of the present invention does not have such a problem.
