The map data stored in the information storage device is divided into longitude and latitude widths of appropriate sizes according to various scale levels, and roads and the like are set as a coordinate set of nodes represented by longitude and latitude. Remembered A road is composed of two or more nodes, and the map data displays roads, buildings, facilities, parks, rivers, etc. on the road layer including a road list, a node table and an intersection node list, and a map screen. Background layers and other map data, and information data for displaying characters and map symbols such as administrative division names such as municipalities, road names, intersection names and facility names.

Further, this navigation device has a route guidance function for allowing the user to easily travel to the desired destination without making a mistake on the road. According to this route guidance function, if you specify the starting point to the destination using the map information and, if necessary, the transit point, you can select the time, distance,
Automatically search for the most suitable route, taking into account conditions such as charges
The searched route is stored as a guide route, and while driving, the guide route is displayed on the map image by changing the color from other routes and making it thicker and displaying it, or the vehicle changes the route on the guide route. When an approaching intersection is approached within a certain distance, the intersection is enlarged and displayed, and an arrow or the like showing the direction to change the course is drawn and displayed on the screen, or voice guidance to turn is used. It is possible to guide people to their destination.

Further, in the navigation device, VI
It is also possible to receive VICS information from the CS information center via radio beacons, optical beacons, or FM broadcasting, import information such as traffic congestion, traffic regulations, search for detours and present new guidance routes depending on the situation. You can do it. Also, due to the recent progress in communication technology and the spread of mobile phones, it is possible to connect a navigation device to an information center that provides various types of information and take in facility information, weather information, etc., as necessary. It is like this.

On the other hand, it is conceivable that due to the recent reduction in communication charges, it becomes possible for future navigation devices to be frequently connected to various external information centers or the Internet and take in various information.

It can be considered that it will be taken in and accumulated in and will be used as needed.

[0009]

With such various means, the destination and arrival time are set in advance so that a travel plan including a stop-by place is set appropriately and a guide route is set. When setting up such a travel plan, there is an observatory near the route to the destination, which has a very good view when it is sunny but hardly sees when it is foggy. Although it was set as a stopover by forecasting that it will be sunny in the estimated arrival time of, when the vehicle is traveling according to the guide route on the day, if it rains unlike the forecast when making the travel plan Alternatively, when it is expected that it will be raining during the expected arrival time at the area during traveling, it is preferable to change the travel plan to a more preferred stop than a stop at the observatory.

Further, it is preferable to change the travel plan when it is predicted that a traffic jam which cannot be predicted at the time of setting the travel plan will occur and the traffic will be significantly delayed from the time scheduled in the travel plan. Also, if you are expected to arrive much earlier than the estimated arrival time because you can travel smoothly without the scheduled traffic congestion, you may wish to add another stop-by place. Or, it may be desired to change the place of stop.

In such a case, the user re-outputs the data such as the destination and the desired arrival time from the present location to the drive center or the navigation device having the function for resetting the travel plan, and the new information is output. You will be asked to re-create a new travel plan and present it to you, and then select from the list and set it again.

However, it is extremely troublesome for the user to frequently check the weather forecast of the stop-by place while driving or to consider whether it is necessary to change the travel plan in consideration of changing traffic information. In addition, the conditions under which a stop-by place in the travel plan is selected are often not clear to the user, so it may not be known that the stop-by place is an unfavorable stop-by place when the weather is in a specific weather. Although it is appropriate to change according to the changes in the conditions from the time of planning, it is highly possible that the trip will continue and the trip will not be comfortable.

Therefore, according to the present invention, when a vehicle is traveling according to a preset travel plan, a condition different from the travel plan preparation condition such as weather forecast and traffic congestion prediction at the time of travel plan preparation occurs. It is an object of the present invention to obtain a drive information providing device capable of appropriately changing a plan at the time. To

In particular, the navigation device 30 is provided with a travel condition judging unit 33 and operates in the same manner as the condition judging unit 6 shown in FIG. 1, but in this example, the weather information fetched from the communication unit 31. Based on information from the center 22, the traffic information center, etc., the travel plan data storage unit 3
Data stored in No. 2, for example, as shown in FIG. 3B based on the travel plan of FIG. 3A is checked to determine whether or not the recommended conditions are met.

Since the travel condition determination unit 33 makes the above determination, the recommended condition data of each stop-by place stored in the travel plan data storage unit, for example, at the stop-by A indicates the temple visitable time zone. Is it possible to arrive by 9 am to 5 pm, or is it possible to arrive at the B restaurant, which is scheduled for lunch, from 11:00 pm to 14:00 pm and 17:00 pm to 21:00 pm
The process of calculating the expected arrival time at each point on a regular basis by further adding traffic congestion information is continued. At the same time, register the periodical weather information capture process at a specific point C,
The communication unit 31 is periodically operated to take in the weather information of the stop-by place C from the weather information center and continuously judge whether or not the condition is met.

When it is determined that the conditions are not met as a result of the determination, the drive information center 11 is contacted to request the creation of a new travel plan, and the user is notified to that effect as necessary. This condition judgment is performed until the arrival at each stop. At this time, the drive information center 11 presents indoor facilities that can be enjoyed even in the rain, such as a visit to an aquarium in the vicinity, instead of the observatory, which is the stop-by place C, and makes it a stop-by place with the user's consent. , Send a guide route to that point. As a result, the user can change the travel plan appropriately without paying attention to the weather at the stop.

In the drive information providing apparatus having the above-described functional blocks, particularly regarding the processing when the drive is started after the travel plan is set, the navigation apparatus operates in order according to the operation flow shown in FIG. 4, for example. Also, in the drive information center, for example, FIG.
By operating in sequence according to the operation flow shown in,
The desired function can be performed as a whole. These operation flows will be described below with reference to the functional block diagram shown in FIG.

In the process of the navigation device, which is an in-vehicle device mounted on the user's vehicle, drive information is acquired mainly on the vehicle speed of the traveling vehicle as shown in FIG. 4 (step S1). Next, the weather / traffic information is acquired (step S2). This is the communication unit 31 of FIG.
The information is taken in from the weather information center 22 and the traffic information center 23 by a mobile phone connected to the.

Then, based on the weather information taken in, in the example shown in FIG. 3, it is judged whether or not the weather at the stop-by place C satisfies the condition of "clear" which is the recommended condition, and
It is judged whether the recommended conditions are met by judging whether it is possible to arrive at the available time of the stop-by place A and the restaurant of the planned lunch place as the next stop-by based on the captured traffic information. .

As a result of this judgment, it is judged whether or not the re-search is necessary (step S4). When it is judged that the re-search is not necessary because the recommended condition is satisfied, the process proceeds to step S2, and the weather / traffic information is continued. Acquisition is performed, and the same operation is repeated thereafter. On the other hand, when it is determined that the recommended condition is not satisfied, and it is determined that the re-search is necessary, the drive information center is requested to re-search (step S5). GPS for this request
The present location data and the desired arrival time such as wanting to arrive at the inn by 5:30 on that day are transmitted.

On the other hand, in the processing of the server in the drive information center, as shown in FIG. 5, it is accepted that a re-search request is made from the vehicle-mounted device to the drive information center by the processing in step S5 of FIG. It waits in the state (step S11), and determines whether or not there is a request for re-search (step S12). If there is no request for re-search here, the process returns to step S11 to repeat the same flow and wait in the accepting state.

When a request for re-search is made, the data of the current position of the user and the data such as the destination and the desired arrival time at the destination are simultaneously transmitted (step S1).
3) Next, the weather information and traffic information of the area from the current location to the destination and the surrounding area are fetched (step S1).
4). As a result, new drive information is generated in consideration of the traffic jam information and the weather conditions in various places (step S15), and the new drive information is provided to the vehicle-mounted device as drive information (step S16).

At this time, the drive information center judges whether or not the partially corrected travel plan created as described above or a new travel plan is desired by the user. Data to be displayed on the screen or output for voice is also transmitted in order to perform the operation. At that time, for example, the restaurant at the scheduled lunch place has the recommended business hours of 11:00 to 14:00 and 17:00 to 21:00, while it is currently 12:00 and is guided by the acquired traffic information. When there was a traffic jam along the route and it was difficult to arrive at the restaurant by 14:00 due to no detour being found, this navigation device said, "If this is the case, I will have lunch." I arrived at the restaurant I was working for after 14:00, and it was the lunch break time of the restaurant. There is a store called △, but would you like to change to that? ”

At the stop-by place B, which is scheduled to arrive at 15:30, the weather is fine as a recommended condition, whereas it is fog at 15:00 according to the weather information.
When it is predicted that the situation will continue after that, it seems that almost nothing can be seen at the planned observatory on the pass at stop-by place C, so " It seems that it has become very bad. Why not change the schedule here and go to the XX museum famous for ☆ ☆? ”, And changed the stopover from an outdoor scenic place to an indoor facility Inquire whether it is okay.

Further, there was no traffic congestion in the area where the traffic congestion was expected, and as a result of running very smoothly, lunch at the B restaurant was finished at the current time, for example, 12:30, and traffic congestion was especially possible after that. It is expected that there will be no habitable area, and if you are likely to arrive at your destination inn more than an hour earlier,
Providing guidance such as “Today went smoothly than I expected. I have more time, so why not go to ◎◎?”.

In the embodiment shown in FIG. 2, as a download type navigation device, the navigation device side is prevented from performing complicated functions as much as possible, and the navigation function is performed by receiving data and information from the drive information center. However, as shown in FIG. 6, for example, as shown in FIG. 6, the book can implement Umei in advance by providing a conventional navigation device with a travel planning function.

In the example shown in FIG. 2, an information center similar to that shown in FIG. 2 is shown as each type of information center. In the navigation device 60, the communication unit can fetch necessary information from these information centers. I am able to do it.

The content information database 3 in the server 1 of FIG.
Similar to the content information database 12 in the drive information center of FIG. 2, map data, facility information, and other vacation information are recorded. Although a DVD-ROM can record an extremely large amount of data, it cannot record a large amount of data like a server in a drive information center, for example. It is possible to supplement by taking in information from the site that provides the information.

This navigation device 63 is provided with a travel plan preparation unit 64 and a guide route calculation unit 65 as the content preparation unit 63, and the stop route is determined by using the guide route calculation unit 65 provided in the conventional navigation device. It is possible to calculate the optimum traveling route including the vehicle and the time required for traveling there. The travel plan created by the travel plan creation unit 64 is recorded in the travel plan data storage unit 64, and the guide route calculated by the guide route calculation unit is the guide route storage unit 5
Stored in 1.

In the other map data processing unit 66, data
Map data processing such as map drawing processing is performed on the DVD-ROM or the like read by the information reading unit 62 based on the map data. At that time, the current position measured by the current position measuring unit 69 is input from the data received by the GPS receiver 68, and the process for drawing the map around the current position is also performed. In addition, in the navigation device 60, the intersection guidance creating unit 70
The image display processing unit 71 performs image display processing to be displayed on the demo 74, and the voice output unit 72 outputs various guidance voices from the speaker 75.

As in each of the above embodiments, a travel condition judging section 73 is provided, and it is recommended that the weather conditions and traffic information taken from the information center determine whether or not the recommended conditions for travel planning are met. When the condition is not met, the travel plan creation unit 64 of the content creation unit 63 in the box navigation device is requested to modify the travel plan.
