JPH10260053A - Destination data annunciator - Google Patents

Abstract

PROBLEM TO BE SOLVED: To inform a user only of destination data really required for the user. SOLUTION: A CPU 12 stores in a memory a position at which a vehicle has come to a stop, the name of a facility at the position and a number of stops in the form of a running history. When the user is informed of data through an HMI(human interface) 22 such as a display, the content of the data is changed in accordance with this running history. For example, if a facility is the one at which the user has not yet stopped the vehicle, a detailed information is delivered. Further, a facility which the user is in particular fond of, is selected among those in the running history, and is preferentially delivered.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a destination information notifying device, and more particularly, to a device for notifying a user of information relating to a destination, which is used in a car navigation system or the like.

[0002]

2. Description of the Related Art In recent years, a navigation device for notifying a route to a destination has been developed and mounted on a vehicle.

[0003] For example, in Japanese Patent Publication No. Hei 6-16320, when a driver first inputs a purpose of use, a candidate for a destination to satisfy the purpose of use is displayed, and then the driver selects a destination. Then, a technique for displaying a route to the selected destination is disclosed. For example, when a department store is input as a purpose of use, a plurality of department stores are displayed, and when a department store is selected, sale information and the like are displayed, and directions to the department store are colored on a map.

[0004]

However, in the above-mentioned prior art, since the past history of the driver is not considered at all, even if the user goes to a department store where he has already visited, the same device is used. Since the destination information is notified, there is a problem that is troublesome for the driver. In addition, even when the purpose of use is input, since only the facilities that match the purpose are listed and the driver's preference is not considered, for example, when the purpose of use is a restaurant and the driver prefers Chinese cuisine, Even so, there is also a problem that it takes a long time to select a desired restaurant since all restaurants such as Japanese, Western, Chinese and the like are displayed.

The present invention has been made in view of the above-mentioned problems of the prior art, and has as its object to change destination information according to a user such as a driver, and to accurately extract only information necessary for the user. It is an object of the present invention to provide an easy-to-use destination information notifying device capable of notifying.

[0006]

In order to achieve the above object, a first aspect of the present invention provides a notifying means for notifying destination information,
It is characterized by having storage means for storing a stop history including a stop position of the vehicle and the number of stops, and control means for changing the contents of the destination information according to the stop history. Thus, the destination (facility) that has been visited many times is different from the destination (facility) that has been visited for the first time, so that unnecessary information for the user is prevented from being reported, and Information can be reported reliably.

According to a second aspect of the present invention, in the first aspect, when the facility where the vehicle has stopped is a facility without a stop history, the control means has a more detailed structure than the case with a stop history. It is characterized by reporting destination information. As a result, detailed information is notified to a destination (facility) that has never been visited, so that an overview of the facility can be easily known, and the purpose that has been visited in the past can be easily obtained. Unnecessary information is not notified to the ground (facility), and the use efficiency of the information is improved.

In a third aspect based on the first and second aspects, the apparatus further comprises search means for reading the destination information from a database, wherein the search means stores the destination information when the facility of the vehicle stops. It is characterized by reading. Instead of always searching for destination information, by searching when the vehicle stops when the user thinks that information is necessary,
The burden on the device can be reduced.

A fourth invention provides a notifying means for notifying destination information, a storage means for storing a stop history including a stop position and the number of stops of a vehicle and a type of a stop facility, and a vehicle history based on the stop history. It is characterized by having arithmetic means for estimating a tendency to stop and control means for changing a facility type of the destination information according to the tendency to stop. Since the stop tendency indicates the user's preference as it is, accurate information notification can be made for each user.

[0010]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of the present embodiment. DGP for detecting the current position of the vehicle
An S (differential GPS) 10 is provided to detect a stop position of the vehicle. The detected current position (including the stop position) is CP
It is supplied to U12. It should be noted that whether or not the vehicle has stopped,
The determination is made based on a signal from the vehicle speed sensor 1 and a signal from the ignition switch 2. Further, a CD-ROM 14 storing map data and information on facilities is provided, and functions as a destination information database. The information center can be used as a database of destination information by mounting the modem 18 and the mobile phone 20 to access an external information center. A memory 16 such as a hard disk (HD) or a RAM stores the history of stopping the vehicle, and stores the stop position and the number of stops of the vehicle. Human Interface (HMI)
Is composed of an in-vehicle display, various switches, and the like.
The destination information from U10 is displayed to notify the user.

In such a configuration, the CPU 10
Although the destination information stored in the D-ROM 14 or the information center is searched and displayed on the display, the present embodiment is characterized in that the content of the displayed destination information is changed according to the traveling history of the vehicle. is there. Hereinafter, a method of recording a travel history and a method of displaying destination information according to the travel history will be described.

FIG. 2 shows a processing flowchart for storing the running history in the memory 16. First, C
The PU 10 determines whether the vehicle speed is zero based on the detection signal from the vehicle speed sensor 1 (S101). If the vehicle speed is zero, the latitude and longitude of the vehicle detected by the DGPS 10 at that time are temporarily registered in the memory 16 together with the time (S
102). Here, the temporary registration takes into consideration that there is a possibility that the temporary registration will be deleted later. Specifically, the temporary registration is stored at a temporary registration address in a memory. Next, it is determined whether or not the user has turned off the ignition key based on a signal from the ignition switch 2 (S103). If the key has not been turned off, it is further checked whether the vehicle speed is zero (S104). If the vehicle speed is not zero, that is, if the vehicle has moved again, the position temporarily registered in S102 is not a stop position. (Temporarily stops only) and clears the temporary memory (S105). Also,
If the vehicle speed is zero in S104, it is determined whether or not a fixed time (for example, 10 minutes) has elapsed since the vehicle was further stopped (S106). If the fixed time has not elapsed, the temporary registration is cleared (S105). If the fixed time has elapsed, it is determined that the user has stopped at the position with a real intention to stop, and the position (and the position) is determined. Is registered in the memory (S107). At the time of registration, the number of stops C at that position is also recorded (if the vehicle has not stopped at the same position in the past, C is set to 1; Is incremented by 1).

On the other hand, if YES in S103, that is, if the key is turned off, the power supply from the battery is cut off.
6 is supplied with backup power (S108). Thereafter, when the user turns on the key (S109), it is determined whether the time from turning off the key to turning on the key is equal to or longer than a predetermined time (for example, 10 minutes) (S110). If it is longer than the predetermined time, it is determined that the vehicle has truly stopped at that position and the actual registration is made in the memory 16 (S111). If the predetermined time has not elapsed, the temporary registration is cleared as in S105 (S112). As described above, the stop position (facility name), its number, and the stop time are sequentially recorded in the memory.

After storing the running history, the CPU 12 evaluates the running history. Specifically, a position with the largest number of stops is determined from the running history for one month, this position is determined as the user's home, and a position with the next largest number of stops is estimated as the user's work place. Next, the number of stoppages of facilities other than the home and the work location is compared with each other. For example, if the number of stops at a restaurant is large in the order of a Chinese restaurant, an Italian restaurant, and a Japanese restaurant, the preference of the user is also determined to be in this order. Furthermore, when the number of stops at the A-chain store is the largest among the number of stops at the gas station, the user determines that the user particularly prefers the A-chain store. Then, after evaluating the traveling history, the CP
U12 displays information on the destination on the display. FIG. 3 shows an example of a screen display for guiding a restaurant. (A) is an initial screen, on which a touch switch 100 for guiding is displayed at the bottom of the map screen. When the user operates the touch switch 100, the screen shown in (B) is displayed, and a list of the user's preference determined from the traveling history is displayed in a list. In the above example, a Chinese restaurant is the first, an Italian restaurant is the second, and a Japanese restaurant is the third. Then, this list is displayed, and a “for the first time” switch 200 is displayed at the bottom of the screen.
This "first time" switch takes into consideration that the user may want to go to another restaurant regardless of his / her own preference. When the user operates the "first time" switch 200, the screen shown in FIG. Transition. On the screen of (C), the types of restaurants displayed on the screen of (B) are rearranged and displayed in a list format. In this list, types of restaurants not displayed on the screen (B), for example, Thai restaurants and Indian restaurants are also displayed in a list. The user can select a desired type of restaurant from these lists. on the other hand,
On the screen of (B), without operating the switch 200 for the first time,
If you select a Chinese restaurant as you like,
Next, the screen of (D) is displayed. In this screen, C
The PU 12 searches for a Chinese restaurant near the current position, and displays a list of the restaurant names in the order of the user's preference determined from the travel history. More specifically, if the number of stop times of the X store, the Y store, and the Z store is 10, 5, and 2, respectively, the list is displayed in this order. Then, when the user selects Store X on this screen, a new menu of Store X, regular holidays, and the like are displayed. Note that since the route to the store X has been performed many times in the past, the CPU 12 determines that the display is unnecessary and does not display it. Also, on this (D) screen, a “for the first time” switch 300 is displayed below the screen. When the user operates this switch 300, the CPU 12 searches for a Chinese restaurant name near the current location that is not displayed in the list of (D) and displays the list. The search may be performed by accessing the information center, or may be performed by accessing the CD-ROM 14 when stored in the CD-ROM 14. When the user selects one of the stores, this store is the first store for the user, and thus the route to the store, the menu, the fee, and the like are displayed in detail.

Instead of displaying information according to the guidance on the screen as described above, when the user stops at a store, the CPU 12 determines whether or not the store has a history of stopping in the past from the running history. If the store has no stop history, after stopping, the user can access the information center or the CD-ROM 14 to search for information on the store and display the store menu and charges in detail. Further, prior to the display, it is also preferable to notify the user that the stopped store is the first time, and after notifying that the store is the first time,
It is also possible to adopt a configuration in which a message such as "Do you need detailed information?" Is displayed on the display, and detailed information is displayed by the user's selection. Of course, if it is determined from the running history that the stopped store has been visited many times in the past, no information is displayed, or only new items such as a special menu are displayed.

As described above, when the store is stopped for the first time, detailed information is displayed as compared with the case where the store is stopped many times, and whether or not the store truly matches the user's own preference is determined. Can be easily determined before actually entering the store (for example, when entering the parking lot of the store).

On the other hand, FIG. 4 and FIG. 5 show a processing flowchart and a screen display example when guiding to a gas station. First, the user specifies a category for which guidance is desired from the category list displayed on the screen (S201). FIG. 5A shows an initial screen, and a facility display switch 40 is provided below the map display on which the current location is superimposed.
0 is displayed, and when this switch 400 is operated, FIG.
A category list of the facility is displayed as shown in FIG.
The user selects a desired category from this list.
It is assumed that the user has selected a gas station (GS).
Next, the CPU 12 reads the running history from the memory 16 (S202), and determines whether the frequency of the A-chain store with the largest number of stops among the gas station stops in the running history is 50% or more of the total number of stops. (S203).
If the maximum frequency is 50% or more of the entirety, it means that the user's taste is strongly expressed.
4 or by accessing the information center and searching (S20).
4). If there is an A-chain store near the current location, the store is displayed on a map (S205). When the A-chain point is displayed on the map, a switch of “other display” is also displayed at the bottom of the screen (S20).
6). This switch takes into account that the user may want to use a gas station other than the A-chain point. FIG. 5C shows an example of a screen on which the A chain store and the “other display” switch 500 are displayed. The user sees "More views" on this screen
When the switch 500 is operated (S207), the CP
U12 searches for all gas stations other than the A chain point around the current location and displays them on the screen (S211).
FIG. 5D shows a state in which all of the A chain point, the B chain point, the C chain point, the D chain point, and the E chain point are displayed.

If the frequency of the most frequently used A chain point is less than 50% in S203, the CPU 12 reads the second most frequently used chain point from the running history in the memory 16, and the sum (A + B) of these points is 50%. % Is determined (S208). If both are 50% or more, it is determined that the user's preference is at the A chain point and the B chain point, and the A chain point and the B chain point around the current location are determined.
The chain point is searched (S209) and displayed on the screen (S210). When displaying the A-chain store and the B-chain store, an "other display" switch 50 is provided below the store.
Displaying 0 is the same as displaying only the A chain store. If there is no A-chain store or B-chain store around the current location, all the gas stations around the current location are searched and displayed (S211 and FIG. 5D). The same applies to the case where there is no A-chain store in S204.

On the other hand, if NO in S208, that is, if the sum of the maximum frequency and the second frequency is less than 50%, the user does not like a specific gas station chain store, and the user does not want to use any gas station chain. When it is determined that the gas station is selected and used, the CPU 12 searches for and displays all the gas stations around the current location (S211 and FIG. 5).
(D)).

Thus, from inside the gas station,
By preferentially displaying a gas station that the user prefers to use (stops preferentially), the user can easily obtain necessary information for himself.

In the above description, a restaurant and a gas station have been particularly described as examples, but the present invention is not limited to this, and can be applied to other information notification.

For example, if it can be estimated from the travel history that the vehicle is heading from home to the work location, no information notification such as route guidance is performed, or only traffic congestion information on the route from home to work location. May be reported.

In addition, since the user's specific preference can be evaluated from the traveling history (the museum is preferred when the number of stops at the museum is large), if the vehicle is traveling to a place other than the work location and is considered for sightseeing, It is also preferable to automatically search for art museums near the current location and display them preferentially.

[0025]

As described above, according to the destination information notifying apparatus of the present invention, the destination information is changed according to the user such as the driver, so that only the information necessary for the user is accurately notified. it can.
