  This device instructs the current position measurement to the mobile phone 7 that has been misplaced through the information transmitting / receiving device 5, receives the positioning information from the mobile phone 7, and acquires the positioning position information by the mobile phone positioning position acquisition means 4a. Then, the control means 4b extracts facilities within a predetermined range from the positioning position as the mobile phone position candidates from the data stored in the information storage means 3, and sets them as destinations for guidance.

FIG. 2 is a diagram for explaining an example in which a facility that has been set as a destination in the past within a predetermined range from the positioning position is extracted as a mobile phone position candidate.
In this example, when positioning position information is acquired from a mobile phone, a facility that is within a predetermined range from the positioning position and has been set as a destination in the past is extracted as a mobile phone position candidate for guidance. Usually, it is considered that it is not so much time to notice that you have forgotten your mobile phone, such as last week, this week, yesterday, today, today's morning, or afternoon. If there is a facility 20 set as a destination within the predetermined range 10 from the positioning position of 7, the facility is extracted as a mobile phone position candidate and displayed on the screen for guidance. The facility 21 is a facility that is set as a destination within the above period, but is located outside the predetermined range 10. In this way, by narrowing down the mobile phone position candidates to the facilities set as destinations in the past from the destination history stored in the information storage means in facilities within a predetermined range from the positioning position, the mobile phone can be efficiently used. It is possible to guide to the facility that was left behind.

FIG. 3 is a diagram for explaining an example in which mobile phone position candidates are extracted from facility data possessed by the in-vehicle navigation device within a predetermined range from the positioning position.
In this example, since a frequently used facility is registered as a memory location, guidance is provided by extracting a facility registered as a memory location as a mobile phone location candidate within a predetermined range from the positioning location It is. If you forget your mobile phone, there is a high possibility that it is a frequently visited facility, so if there is a memory point 30 within the predetermined range 10 from the positioning position of the mobile phone 7, that point is extracted as a mobile phone position candidate and displayed on the screen Give guidance. In this example, since there are a plurality of memory spots 30 as shown in the figure, guidance is performed in the old or new order based on the order given by the user or the registration date and time. A facility 31 is a facility at a memory location but outside the predetermined range 10. If there is no mobile phone at the memory location, or there is no memory location, there is no chance of forgetting on the road, so other facilities within the predetermined range 10 from the positioning location, such as familiar restaurants and Restaurants and the like may be guided as mobile phone position candidates. Thus, by narrowing down the mobile phone position candidates to the facility data of the in-vehicle navigation device within a predetermined range from the positioning position, it is possible to efficiently guide to the facility that has been misplaced.

FIG. 4 is a diagram for explaining an example in which facilities along a road that have traveled within a predetermined range from a positioning position are extracted as mobile phone position candidates.
In this example, in consideration of the travel history, a facility that is within a predetermined range from the positioning position and that has traveled or is near the road is extracted as a mobile phone position candidate for guidance. Forgetting the mobile phone cannot be at least a facility along the road with no driving history, and therefore, along the road 40 with the driving history within the predetermined range 10 from the positioning position of the mobile phone 7 or in the vicinity thereof (from the road The facility 50 (within a predetermined distance) is extracted as a mobile phone position candidate and displayed on the screen for guidance. The facility 51 is a facility along the road 40 where it has traveled, but indicates a facility outside the predetermined range 10. Since there are usually a plurality of roads stored as the travel history, facilities along the road are guided as mobile phone position candidates in order based on the criteria such as the number of times of travel or the date of travel is new. In this way, by narrowing down the mobile phone position candidates within a predetermined range from the positioning position and along the road that has traveled or near the road, it is possible to efficiently guide the facility that has been misplaced.

FIG. 5 is a diagram illustrating an example in which a point that has stopped within a predetermined range from a positioning position is extracted as a mobile phone position candidate.
This example is a case where guidance is performed by extracting a point within the predetermined range from the positioning position and a facility that has visited in the past or a facility in the vicinity thereof as a mobile phone position candidate. Since it is a facility that has at least visited the mobile phone, it is assumed that the mobile phone is forgotten. It is extracted as a position candidate and displayed on the screen for guidance. The facility 61 is a facility at the point of stop, but indicates a facility outside the predetermined range 10. The point where the engine has stopped may be a point where the engine has been turned off. When there are a plurality of facilities at or near the place where the user has visited, the guidance is given with an order based on the number of visits or the newest order of visit dates. In this way, it is possible to efficiently guide to a misplaced facility by narrowing down the mobile phone position candidates to a point where the user has stopped at a facility within a predetermined range from the positioning position or a facility in the vicinity thereof. .

  In addition, although the place forgotten to carry is extracted based on the destination history, the facility data such as the memory point, the travel history, and the stop point shown in FIGS. 2 to 5, for example, in the destination history data If the phone position candidate cannot be extracted, the mobile phone forgotten place is extracted from the stop point data. If the mobile phone position candidate cannot be extracted from the stop point data, the next data such as the memory point is extracted. The mobile phone position candidates may be sequentially extracted from other viewpoints, such as extraction of a mobile phone forgotten place.
