2. Description of the Related Art A navigation device that guides a vehicle so that a driver can easily reach a desired destination detects a vehicle position and reads map data around the vehicle position from a CD-ROM. In addition, a map image is drawn on a display screen, and a vehicle position mark (own vehicle position mark) is drawn at a predetermined position on the map image. Then, as the current position changes due to the movement of the vehicle, the own vehicle position mark on the screen is moved, or the own vehicle position mark is fixed at a predetermined position such as the center of the screen and the map is scrolled. The surrounding map information can be understood at a glance.

Such a navigation device has a route guidance function of searching for a guidance route from a departure point to a destination, displaying the guidance route on a map, and performing intersection guidance (enlarged intersection, display of traveling direction). ing. When a departure point and a destination are input, the guidance route control unit of the navigation device automatically determines an optimal guidance route and continuously stores nodes (latitude and longitude) constituting the guidance route in the guidance route memory. At the time of actual traveling, a search is made for a guidance route included in the map display area of the screen from the node sequence stored in the guidance route memory, and the guidance route is displayed so as to be distinguishable from other roads, and the approach route is displayed. When the vehicle is within a predetermined distance from the middle intersection, an intersection guide map (an enlarged view of the intersection and an arrow indicating the traveling direction at the intersection) is displayed, which road should be traveled, and which direction should be taken at the intersection. You can see it. When the vehicle deviates from the guidance route (off-route), the guidance route from the current vehicle position to the destination is recalculated to update the guidance route.

The input of a destination is performed by displaying a map including the destination on a display screen and designating the destination with a cursor (focus). To display the destination, scroll the map, display the registered point list registered in the memory, specify the name of the registered point to be the destination, do it by genre and region And a method of indicating a desired destination (sightseeing spot, hot spring, hotel, golf course, etc.), or a method of indicating and displaying facilities based on town page data.

When entering a destination by specifying facilities (department stores, banks, hotels, etc.) using genre-specific information or town page data, it is necessary to search for a parking lot after reaching the destination, which is time-consuming. Lost. For this reason, a beacon receiver is provided, and a parking lot of an empty car around the current position of the vehicle is obtained from the VICS information, and displayed on a map in a superimposed manner, and parking lot information such as business hours, fees, and height restrictions is appropriately displayed. A method has been proposed (JP-A-7-301543). Also, when the destination is set by the facility name, when the vehicle is within the set distance from the destination (facility), the parking lot accompanying the facility (underground parking lot, rooftop parking lot, outdoor parking lot)
Is searched with the first priority, and the general parking lots are searched with the second priority, the third priority,... In order of proximity to the facility, and if the empty parking lot is found as a result of the search, the parking lot is displayed on a map. A method of displaying a charge and the like in addition to the overlapping display has been proposed (Japanese Patent Application Laid-Open No. H4-142421).

[0006]

By the way, department stores,
Although facilities such as hotels have their own parking lots (in-facility parking lots), they may be too small. In particular, such a situation frequently occurs in an urban area where parking space cannot be secured. Therefore, in many cases, the facility contracts with a manager who manages a parking lot so that the facility can park in a general parking lot (partner parking lot) which is not its own. In this way, when partner parking exists in addition to on-site parking,
It is necessary to treat partner parking lots equivalent to on-site parking lots.
However, the conventional parking lot display method is a display method that does not consider the partner parking lot at all, and thus there is a problem that the driver cannot effectively use the partner parking lot.

Accordingly, a first object of the present invention is to provide a parking lot display method capable of displaying a partner parking lot together with an on-site parking lot on a map. A second object of the present invention is to provide an in-facility parking lot, a parking lot other than the partner parking lot, and a parking lot close to the facility,
An object of the present invention is to provide a parking lot display method for displaying on a map so that it can be distinguished from partner parking lots. A third object of the present invention is to determine the degree of congestion such as full / congested / empty at each parking lot by V.
It is an object of the present invention to provide a parking lot display method capable of recognizing from outside information such as ICS information and displaying a parking lot in a form in which a full / congested / empty vehicle can be identified. A fourth object of the present invention is to set a guidance route from a facility to a parking lot which is the closest to the vacant parking lot among a number of parking lots in a facility and partner parking lots. It is to be able to be guided to the parking lot.

[0008]

According to the first object of the present invention, there is provided a parking lot display method in a navigation device for displaying a peripheral map of a facility designated by a facility search on a display screen. When the correspondence with the parking lot which the facility is affiliated with is stored and the surrounding map of the facility designated by the facility search is drawn, the partner parking lot of the facility is obtained from the correspondence relationship, and the surrounding map is obtained. This is achieved by displaying a parking lot mark at the partner parking lot location. According to the second object, according to the present invention, the location information is stored for each parking lot, and the parking lot mark of a parking lot other than the partner parking lot and close to the facility is associated with the parking lot. This is achieved by superimposing and displaying the surrounding parking map so as to be distinguishable from the parking lot mark of the preceding parking lot.

According to the third object of the present invention, according to the present invention, congestion degree information of a partner parking lot and a parking lot in a facility is obtained from the outside, and a parking lot mark is displayed so that the degree of congestion can be identified. This is achieved by: The fourth object is to

(E) First Parking Lot Display Control FIG. 5 is a processing flow of the first parking lot display control, and FIG.
It is an explanatory view of a parking lot display control. When the user selects a facility as a destination by facility search (step 10)
1) The map reading control unit 11 obtains the facility position data, the facility partner parking lot name, and the facility auxiliary parking lot name from the facility database 10d (see FIG. 2) in the CD-ROM 4 (step 102). Next, the map readout control unit 11 obtains the parking lot information of the facility partner parking lot and the facility-related parking lot from the parking lot database 10e (FIG. 2) of the CD-ROM 4, and outputs the parking lot position data PKP to the mark generation unit 2.
5 and other parking lot information PIF is input to the operation screen generator 24 (step 103). Thereafter, the map reading control unit 11 reads the map data around the facility from the CD-ROM 4 into the map buffer 12 and displays it on the display device 3 (step 104). Further, the mark generation unit 25 displays the parking lot marks 51a to 51e at the parking lot positions on the surrounding map as shown in FIG. 6A based on the inputted parking lot position data PKP (step 10).
5). Incidentally, a focus (cursor) 52 is displayed on a facility (not shown). In addition, 51a is a parking lot mark of the in-facility parking lot, and 51b to 51e are partner parking lot marks.

In this state, the joystick key 2a

The joystick key 2a is depressed (step 107). As a result, as shown in FIG. 6B, the operation screen generating unit 24 returns “return”, “destination”, “passing point”, “registered point”,
Display the selection menu of "parking lot" (step 10)
8). Here, when the joystick key 2a is operated to select a parking lot item (step 109), the operation screen generating unit 24 outputs the parking lot of the parking lot designated by the focus based on the parking lot information PIF already input. The information is displayed as shown in FIG. 6C (step 110).

Thereafter, if it is necessary to display other parking lot information, the "return" item is selected to return to the previous screen (step 1).
11, 112), and repeat the processing from step 106. If it is not necessary to display the parking lot information, the screen is changed to a screen corresponding to the next operation (step 113), and the parking lot display is ended. The above is the case of the parking lot display in the surrounding map display after the facility search operation, but the facility searched by the parking lot search is input as the destination, and the vehicle approaches the target facility and the vicinity of the target facility is displayed on the map. When the map is displayed, the parking lot marks 51a to 51e are displayed as shown in FIG. 6A, and the parking lot information is displayed upon request. That is, when the parking lot position is included in the map displayed on the display screen, the mark generating unit 25 displays the parking lot mark at the parking lot position.

In the above description, the focus is moved to select the parking lot whose parking lot information is to be displayed. However, such a focus moving operation is troublesome. Therefore, it is possible to sequentially change the parking lots for which the parking lot information is to be displayed only by selecting the menu items and to display the parking lot information. FIG. 7 is a processing flow of such parking lot display control, and FIG. 8 is an explanatory diagram of parking lot display. Steps 101 to 105 are the same as those in FIG. As shown in FIG. 8A, when the parking lot marks 51a to 51e are displayed on the map around the facility (Step 105), the joystick key 2a is pressed (Step 106). As a result, as shown in FIG. 8B, the operation screen generator 24 displays a selection menu of “parking lot”, “destination”, “passing point”, “registered point”, and “return” at the lower part of the screen. (Step 107). Here, when the joystick key 2a is operated to select a parking lot item, the mark generation unit 25 causes i + 1 → i (the initial value of i is 0).
(Step 108), and as shown in FIG.
The second parking lot mark 51a is displayed so as to be distinguishable from others (for example, by color coding) (step 109).

Next, when a parking lot item is selected with the joystick key 2a (already selected in step 108) and the joystick key is depressed (step 110), the operation screen generating section 24 displays the parking lot that has already been input. Based on the information PIF, the parking lot information of the ith parking lot is displayed as shown in FIG. 8D (step 11).
1). Thereafter, it is determined whether or not other parking lot information needs to be displayed (step 112).
The following processing is performed.

For example, the joystick key 2a
Is operated to select the parking lot item, the mark generation unit 25
Is i + 1 → i, and the ith parking mark 51b is displayed so as to be distinguishable from the others, as shown in FIG. 8 (e). Then, select the parking lot item with the joystick key 2a,
When the joystick key is pressed, the operation screen generator 24 displays the parking lot information of the i-th parking lot based on the parking lot information PIF that has already been input, as shown in FIG. 8 (f). On the other hand, if it is not necessary to display other parking lot information, the screen is changed to a screen corresponding to the next operation (step 11).
3), the display of the parking lot ends. According to the above, since the operation of moving the focus is unnecessary, the parking lot can be switched one after another and the parking lot information can be displayed.

(F) Second Parking Lot Display Control In the first parking lot display control, a parking lot mark of a partner parking lot around the facility and a parking lot in the facility is displayed.
A general parking lot close to the destination facility can also be displayed. This is convenient when the partner parking lot or the parking lot in the facility is full. FIG. 9 is a process flow of the second parking lot display control, and FIG. 10 is an explanatory diagram of the second parking lot display control.

When the user selects a facility as a destination by searching for a facility (step 201), the map reading control section 11 causes the facility database 10d in the CD-ROM 4 to read.
(See FIG. 2), the facility position data, the facility partner parking lot name, and the facility supplementary parking lot name are obtained (step 20).
2). Next, the map reading control unit 11 is provided with a CD-ROM.
The parking lot database 10e (FIG. 2) retrieves the parking lot information of the facility partner parking lots and the parking lots attached to the facility from the parking lot database 10e of FIG. Is input to the mark generation unit 25, and the retrieved parking lot position data PKP and data indicating the distinction of in-facility / affiliate / general parking lot are input to the mark generation unit 25, and other parking lot information PIF is input to the operation screen generation unit 24. (Step 20
3,204).

After that, the map reading control unit 11 sends the CD
-Map data from the ROM 4 around the facility is stored in the map buffer 1
2 is displayed on the display device 3 (step 205). The mark generating unit 25 moves the parking lot position on the surrounding map based on the inputted parking lot position data PKP as shown in FIG.
As shown in FIG. 0 (a), the parking lot marks 51a to 51e of the in-facility parking lot and the partner parking lot and the parking lot marks 53a and 53b of the general parking lot are displayed so as to be distinguishable (for example, color-coded) (step 206). .

Thereafter, predetermined parking lot information is displayed on the display screen by the same processing as the first parking lot display control (steps 106 to 113). For example, the joystick key 2a is operated to move the focus 52 to a desired parking lot mark 53a (step 106), and the joystick key 2a is pressed (step 107). As a result, as shown in FIG.
4 is "return", "destination", "passing point",
A selection menu of "registration point" and "parking lot" is displayed (step 108). Here, joystick key 2
a is operated to select a parking lot item (step 10).
9), the operation screen generating unit 24 displays the parking information of the parking lot designated by the focus based on the parking information PIF already input (step 110). Since then
If it is necessary to display other parking lot information, the "return" item is selected to return to the previous screen (steps 111 and 112), and the processing after step 106 is repeated. If it is not necessary to display the parking lot information, the screen is changed to a screen corresponding to the next operation (step 113), and the parking lot display is ended.

In the above description, the parking lot is displayed in the surrounding map display after the facility search operation. The facility searched by the parking lot search is set as the destination, and a guidance route to the destination is generated. When the vehicle guides the vehicle along the route and the vehicle approaches the target facility and the map around the target facility is displayed on the map, the parking lot marks 51a to 51e, 53a, 53b is displayed, and parking lot information is displayed upon request. That is, the mark generation unit 2
5 displays a parking lot mark at the parking lot position when the parking lot position is included in the map displayed on the display screen.
