Here, if the change button 56 is selected by the user, it is determined that the user does not want to go to the facility where the user has previously stopped, and the facility relating to the facility which has not been stopped yet is determined based on the contents of the history memory. I try to provide information. Further, when the history button 57 is selected by the user, the type of restaurant, the position of each restaurant, the name of each restaurant, the date,
A history table storing the time and the like is displayed.

The facility information provided in this manner may be facility information on a facility selected from facilities which have been visited based on the past history, or may take into account the type of facility found from the history. The facility information may be such that facilities that have not been visited before are provided with priority. FIG. 4 is a flowchart for explaining a procedure for selecting and displaying facility information based on the contents of the history memory in the embodiment of FIG. Control means 3 for selecting appropriate facility information based on this flowchart
The operation of FIG. 1 will be described.

In the flowchart shown in FIG. 4, first, the current time is detected by operating the control means 3 (see FIG. 1) in the navigation device (step S1). Next, it is detected whether or not the current time is a predetermined time, or whether or not the current time is included in a predetermined time zone (step S2). For example, 7:00 to 9:00 is a morning time zone, 12:00 to 14:00 is a day time zone, and 19:00 to 21:00 is a night time zone.

A plurality of facility information is classified according to the time zone of morning, daytime or night and stored in the history memory in advance. If the current time is included in any of the time zones, the facility information of the time zone classified according to the current time is displayed by referring to the history memory (step S3). in this case,
Information on the occupants using the facilities (occupant data) may also be stored in the history memory, and the corresponding information may be provided. For example, when visiting a facility once with a preview, facility information can be selected based on current occupant and historical occupant data.

If the current time does not coincide with the above-mentioned predetermined time zone and does not fall into any of the morning, noon and night time zones (step S4), the service for providing facility information is provided. Indicates that it is outside the target time. Further, when a request to execute a service for providing facility information is made by a user (step S5), the above-described processing of step S3 is performed.

Further, it is detected whether or not a predetermined time or more (T or more, T is an arbitrary positive number) has elapsed from the time of the previous stop at the facility (step S6). For example, it detects whether 24 hours or more have passed since the last meal. 2
When it is determined that four hours or more have elapsed (step S7), facility information of a facility that is frequently used in a plurality of histories is preferentially provided. If it is determined that the time has not passed for 24 hours or more (step S8), facility information of a facility different from the facility used within 24 hours is provided. For example, facility information of a facility having the second highest frequency, facility information of a facility having the lowest frequency, or the like can be considered. Here, the predetermined time is set to 24 hours, but it is not limited to 24 hours, and it is also possible to simply select a facility of a type other than the last time.

When the contents of the history memory are displayed on the display means, they may be displayed in descending order of the frequency of the history memory, or may be displayed in ascending order of distance or time to the facility.

[0039]

As described above, according to the present invention, the facility information of the user's favorite type is selected based on the history memory in which the type information and the date and time information of the facility visited before are stored in advance. Since it is determined whether or not the facility information has just been selected and whether or not to select facility information of other types, it is determined whether or not the user has to operate the selection button or the like many times. It becomes possible to easily provide facility information according to feelings.
