Abstract

PURPOSE: To provide navigation apparatus which eliminates a troublesome operation such as a daily-indentical-route setting operation or the like in the case of commuting or the like by a constitution wherein, on the basis of the actual results of a route search in the past, a commonly used starting place in a time zone for starting the apparatus and a destination can be estimated and searched automatically. CONSTITUTION: A storage part 18 is constituted of a RAM and the like. In the storage part 18, a day of the week in the past, a starting place in every time zone, a destination and a route search frequency are stored. When a navigation apparatus is used (i.e., the navigation apparatus is started), the starting place and the destination in which the route search frequency is highest in the day of the week and the time zone in its starting operation are searched so as to be read out by a microcomputer 16. The microcomputer 16 takes into account traffic information by a traffic information receiver 13, and it searches a route which is regarded as optimum so as to be output to a display part 17. A timer 19 has a function to clock a present time and a function to start the navigation apparatus before a prescribed time in the time zone of the set day of the week, and it usually outputs the present time to the microcomputer 16. The prescribed time is nearly the same time as the time required for a route search.

Next, the operation of this embodiment will be described with reference to FIG. FIG. 3 is a flowchart showing the processing of the microcomputer 16. When the power switch is turned on or the timer 1
When the process is started by 9 before a predetermined time from the set time, the process is started. In step S1, if the power switch is turned on to activate the vehicle, the starting day and destination having the highest frequency of route search in the activated day and time are read out.
When started by the timer 19, the storage unit 18 stores the searched route with the highest route search frequency for the day of the week and the time zone (there is a difference of a predetermined time from the start time) set by the timer 19.
Search for the destination and read out its origin and destination
Move to 2. For example, start up at 8:00 on Monday or timer 1
If it is set to 9 o'clock on Monday, the departure point A and the destination B with the highest route search frequency are read. In step S2, the traffic information from the traffic information receiver 13 is obtained, and the process proceeds to step S3. In step S3, the optimum route is searched based on the departure place, the destination, and the traffic information from the traffic information receiver 13 read from the storage unit 18, and the process proceeds to step S4. In step S4, the optimum route is output to the display unit 47, and the process proceeds to step S5. Step S5
Then, the route search frequency corresponding to the starting point and the destination of the route search in the storage unit 18 is incremented (count:
1 is added), and the process ends. Note that step S5 may be between step S1 and step S2. In addition, when the departure point and the destination are input from the input unit 11 (the storage unit 18

As described above, according to this embodiment, the starting point and the destination in the past route search are stored together with the route search frequency for each time of day and used (the navigation device is activated). By reading out the departure place and destination with the highest frequency of route search in the past route search during the day of the week and setting them as the departure place and destination, the route search is performed, and the same for every day, such as commuting. Point of departure,
Even if it is a destination, it is possible to eliminate the troublesomeness of having to enter the starting point and the destination etc. each time it is used. Further, by setting the use time of the navigation device, the route search is performed in advance before the use of the navigation device, and the route search is already completed at the time of use, so that the waiting time for the route search is reduced or eliminated. Further, since it is stored for each day of the week, it is possible to deal with the case where the action form is different, such as Monday to Friday, Saturday, and Sunday. Further, in the present embodiment, the map data is stored by the CD-ROM, but other storage media may be used, and the map data sent by FM multiplex broadcasting or the like may be stored. . Further, in the present embodiment, the navigation device is activated in accordance with the set time, but it may be activated intermittently, for example, at regular intervals, in which case it is not necessary to set the time and Sometimes it is convenient because the route search is completed.

Another embodiment will be described below. In this embodiment, when searching for a past route search, the place of departure is limited. That is, since the current vehicle position can be detected by the vehicle position detection means 12, the limitation is set on the vehicle position as the starting point, and the starting point is set in the past route search in the time zone when the navigation device is started. The route search having the highest frequency of route searches among the current positions is searched, the destination is read from the storage unit 18, and the route search between the current position and the read destination is performed. That is, in the process of step S1 in FIG. 3, a restriction that the starting place is the present position is added as a search condition. In this case, when searching for past route searches, the departure place within a predetermined distance from the current position may be treated as the same position as the current position. As described above, according to the present embodiment, the route search from the current position is performed and the result is displayed, so that a more convenient route search is performed.

As described above in detail, according to the present invention, a route search is performed by automatically estimating a departure place and a destination from a past route search, so that it is possible to carry out the route search every day such as commuting. It is possible to eliminate the troublesomeness of having to enter the starting point and the destination each time the device is used, even though the starting point and the destination are the same. Further, by setting the use time, the route search is performed before the use, and the route search is already completed at the time of use, so that the route search waiting time can be reduced or eliminated. In addition, since it is stored according to the day of the week, it is possible to deal with the case where the action form is different, such as Monday to Friday, Saturday, and Sunday.
