Abstract

PROBLEM TO BE SOLVED: To surely announce desired facilities to be last along a guidance route. SOLUTION: When a user sets a destination, a route from a present location to the destination is computed and set (step S1-S4). Then in the case of an input instruction for specific types, such as convenience stores, service areas, or gas stations, the location of the facilities of the specific type to be the last before the destination is retrieved. Furthermore, in the case that the set route passes along a specific type of road (e.g. an express way), the location of a specific type of particular facilities, such as a gas station to be the last before an entrance to the express way is retrieved (steps S5 and 6). When travel guidance on the route is started (step S7), location information on the last facilities is announced, with normal travel guidance (step S8).

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a navigation device and a program for notifying information about facilities on a set route.

[0002]

Conventionally, in a navigation device, when a user sets a destination, a route from the current position to the destination is calculated and set. And
While traveling along the route, a travel guide is output each time a guide point is reached. For example, a guidance sound such as "This is a rightward point of xxxxm" is output.

Incidentally, a recent navigation device (car navigation device) has, for example, a function of “nearest information guidance”. This is because if you set a “genre” for which you want information in advance, the name of the facility (restaurant name, gas station name, or convenience store name) near the route is displayed or voiced sequentially as you move. This is to provide guidance (notification).
However, this conventional function cannot recognize the last facility name for the destination. For example,
Even if it is set to notify the convenience store on the route, it is not known which convenience store is the last for the destination.

The present invention has been made in view of the above-mentioned circumstances, and an object of the present invention is to make it possible to reliably notify a desired last facility along a guide route.

[0005]

According to the first aspect of the present invention, a destination is selected from among the facilities on or along a route searched based on the genre input by the name input means or the facility names in the same genre. On the other hand, the last facility is notified by the notification means. Therefore, there is no risk of missing a desired facility such as the last convenience store or a roadside station along the guide route for the destination, and the convenience is increased.

According to claim 2, the destination is a campsite,
When a specific genre is related to leisure spots such as a ski resort and a beach, the facility that is the last one for the destination among the facilities corresponding to the specific genre is notified that the facility is the last one. I do. Therefore,
There is no risk of missing the desired last facility along the guide route for the destination, and convenience is increased.

According to the third aspect, the presence of the last facility can be notified at an appropriate timing. According to claim 4, when the set route passes through a specific type of road (for example, a highway), among the facilities (for example, gas stations) existing on or around the route before reaching the road, Information to that effect is reported to the last facility. Therefore, there is no risk of overlooking the last desired facility along the guide route before reaching a specific type of road to the destination, and convenience is increased.

According to the fifth aspect, it is possible to configure a program capable of obtaining the same operation and effect as the first aspect of the invention. According to the sixth aspect, it is possible to configure a program capable of obtaining the same effect as the second aspect.

1 and 2 show a first embodiment of the present invention. As shown in FIG. 1, a car navigation device 1 includes a map data storage device 2 as a data storage unit.
A position detection device 3 as a current position detection device and a traveling direction detection device, a display device 4 as a display device, a switch group 5 as a destination input device and a name input device,
An audio output device 6 as a notifying unit, a route setting unit,
A control device 7 is provided as search means and notification control means.

The map data storage device 2 stores a plurality of facility information classified by genre, in addition to map information. This facility information includes information on various genres related to facilities such as convenience stores, fast food stores, roadside stations, gas stations, and highways, and further, for each genre, for example, the same affiliated store (same store) of a convenience store, Each facility of the same gas station has a facility name (unique name) associated with location information. Also, each of these facilities is provided with a symbol mark (landmark).

The position detecting device 3 includes a GPS receiver 8, a gyro 9, a vehicle speed sensor 10, and the like, and can detect a current position and a traveling direction of the vehicle. The control device 7 includes a microcomputer, and includes an input / output unit (I / O) 11, a central processing unit (hereinafter, MPU) 12, and a memory 13. The I / O 11 is connected to the above-described map data storage device 2, display device 4, switch group 5, audio output device 6, GPS receiver 8, gyro 9, vehicle speed sensor 10, and the like.
The MPU 12 is a control unit of the navigation device.

The memory 13 comprises a ROM and a RAM.
The ROM stores a program for the car navigation device (a program for the navigation device) and the like. This program causes the MPU 12 to execute various procedures. The RAM is used not only as a work memory but also for temporarily storing various data. The MPU 12 of the control device 7 executes various processes based on various input signals and programs provided to the control device 7.

Among the various processes of the MPU 12, those relating to the route setting means, the search means, and the notification control means will be described with reference to the flowchart of FIG. In the figure, in step S1, it is determined whether or not the user has set a destination in the control device 7 by the operation switch group 5, and when the destination is set, the process proceeds to step S2, and the destination is changed from the current position to the destination. Calculate the route to and search. In this route search, calculation is performed based on, for example, the Dijkstra method, and a recommended route determined by the MPU 12 to be optimal, a toll road priority route, a general road priority route, and the like are searched as traveling routes. At this time, although not shown, the display device 4
Is displayed as to whether or not to confirm the searched route.

In step S3, it is determined whether or not an input for instructing confirmation has been made by an appropriate switch of the operation switch group 5.
Then, the process goes to 4 to set (determine) the searched route as a traveling route. These steps S2 to S4 constitute a route setting means.

Thereafter, the flow shifts to step S5, where it is determined by the switch group 5 whether or not an instruction to input a specific genre such as a convenience store, a roadside station, or a gas station has been issued. If there is an input instruction, the process proceeds to step S6 to search for the position of the last specific facility on the set traveling route from the plurality of facilities included in the specified genre with respect to the destination. For example, if "gas station" is entered, a plurality of unique facilities as "gas stations" are searched on the set route, and the position of the last "unique facility related to gas station" with respect to the destination is located. Search for. Further, in this step S6, when the set route passes through a specific type of road (for example, a highway), the entrance of the "highway" is regarded as a virtual destination, and the last Is searched for a specific facility such as a "gas station".

When route operation guidance is started by the operation switch group 5 ("YE" in step S7).
S)), the process proceeds to step S8, and the normal voice guidance, that is, the vehicle travels to the voice output device 6 at, for example, 700 m, 300, and immediately before the intersection or the branch where the course should be changed in the set route. The guidance is notified by display and voice. For example, a guidance voice such as "It is 300 m to the right" is output immediately before 300 m, and a guidance voice such as "shortly to the right" is output immediately before, or a direction to turn is displayed by an enlarged view of an intersection or the like.

Further, in this step S8, along with the voice guidance, positional information on the last facility is notified. That is, when the position of the last gas station with respect to the destination is searched, for example, approximately 700 m before the gas station, a guidance sound such as “The gas station 700 m ahead will be the last gas station to the destination” Is output to the audio output device 6. The same sound output is performed 300 m before, and almost immediately before the gas station, a sound output such as “the gas station immediately before will be the last gas station to the destination” is performed. In addition, in addition to or instead of the audio output, a notification by display may be performed.

In step S8, if there is an expressway on the set route, a similar sound is output at the last gas station at the entrance. For example, in front of 300m, "30 minutes ahead
A gas station at 0 m will be the last gas station up to the entrance of the highway. "And almost immediately, for example, an audio output such as" The gas station just ahead will be the last gas station up to the entrance of the highway. " If there is no expressway on the set route, the voice guidance is not provided.
In addition, in addition to or instead of the audio output, a notification by display may be performed.

If it is determined in step S5 that there is no input of a specific genre, the process proceeds to step S9 according to "NO", waits for the start of route travel guidance, and performs normal travel guidance in step S10. .

If a plurality of genres are input in step S5, the same operation as described above is performed for a plurality of facilities included in each genre.

According to the first embodiment, since information on the last convenience store, a roadside station, a gas station, or the like is notified by voice to the destination designated and set in advance, the destination is notified to the destination. There is no danger of overlooking the last facilities such as convenience stores and roadside stations, which increases convenience. In addition, the facility related to the input specific genre is a specific type of road on the route (for example, an expressway or a toll road).
On the other hand, when it is the last facility, information to that effect is notified by voice or display. Therefore, there is no possibility of missing the last facility for a specific type of road, and the convenience is further increased.

As can be understood from the above description, the program provided in the ROM of the memory 13 includes a procedure for setting a route to the destination in the MPU 12 as the control means, and a facility name inputted by a predetermined operation. Is searched for on the set route, and when the facility becomes the last facility for the destination, a procedure for informing that the facility is the last is executed.

FIG. 3 shows a second embodiment of the present invention, and differs from the first embodiment in the following points. The memory 13
It has a configuration in which a storage area is provided as facility corresponding data storage means for storing a specific genre and a specific facility associated therewith. In this case, as the specific genre, for example, a leisure spot different from a single facility (building) such as a campsite, a ski resort, a beach, and the like is stored in advance, and a specific facility (building) associated therewith is, for example, a convenience store. , Gas stations are remembered. The specific genre and the specific facility associated therewith may be input and set by external input means. Further, a specific genre and a specific facility associated therewith may be stored in the map data storage device 2.

In the following description, steps S10 to S40 and S70 to 100 in the flowchart of FIG.
Since they are the same as those described above, their description is omitted. When the route is set in step S40, it is determined in step S50 whether the set destination is a specific genre (for example, a campsite). If the specific genre is the destination, the process proceeds to step S60. Then, a specific facility (in this case, a convenience store, a road station, a gas station, etc.) associated with the destination is searched on the set route, and the last convenience store, gas station, etc., for the destination is searched. Search for a location. Thereafter, the same processing and determination as in the first embodiment are performed.

According to the second embodiment, if the input destination is of a specific genre such as a campsite, a ski resort, a beach, etc., the facility associated with the campsite, the ski resort, or the beach ( For example, convenience stores, roadside stations, or gas stations) are automatically set as search targets. Therefore, it is not necessary to input a genre name for notifying the last facility, and as a result, the convenience is further improved.

It is to be noted that while the destination is a specific genre,
The last facility to be notified may be selected by the operator in advance. In this way, only the intended type of facility can be notified.

In the second embodiment, the memory 13
In addition to causing the MPU 12 to execute a procedure for setting a route to a destination, the program provided in the ROM of
Searching for the facility associated with the destination on the set route, and when the facility is the last facility for the destination, performing a procedure of notifying that the facility is the last. Has become.

When a specific genre is set as a destination, any one of a campsite, a ski resort and a beach may be used, or another specific genre may be set as a destination. further,
The facilities associated with the destinations of these specific genres may be other than convenience stores, roadside stations, and gas stations.

The present invention is not limited to the above embodiments, but may be modified as follows. For example, whether or not to notify the last facility may be selected by a manual operation switch or the like.

In addition to the notification of the last facility during traveling, the notification may be made, for example, when confirming all routes after setting the route. Furthermore, in each of the above-described embodiments, the car navigation device has been exemplified, but the present invention is also applicable to a portable navigation device.

Further, in addition to the genre input, a name input for the same affiliated store in the same genre (for example, a convenience store name input in a genre called a convenience store) may be used. Further, the last facility search may be on the periphery of the route (for example, 100 m in the horizontal direction along the route) other than on the route.
