Identification code), major classification type, minor classification type, unique name, and position information.

  A control circuit (corresponding to a computer) 19 executes a program for the operation of the vehicle navigation apparatus 1 read from the ROM 17 and the external storage medium 18, and in executing the program, the RAM 16, the ROM 17, and the external storage medium 18. Information is read out from the RAM 16 and written into the RAM 16 and the external storage medium 18, and signals are exchanged with the wireless communication circuit 10, the position detector 11, the operation switch group 12, the image display device 13, and the audio circuit 14.

  Specific processing performed by the control circuit 19 executing the program includes current position specifying processing, destination specifying processing, guidance route calculation processing, route guidance processing, and the like.

  The current position specifying process is a process for specifying the current position (for example, latitude, longitude) and direction (for example, east, west, north, and south) of a vehicle based on a signal from the position detector 11 using a known technique such as map matching. . In the following description, the current position used by the control circuit 19 is calculated using this current position specifying process unless otherwise specified.

  The destination specifying process is a process for specifying a destination as a route guidance target based on a user operation on the operation switch group 12 or the like.

  The guidance route calculation process is a process for calculating an optimum guidance route from the current position to the destination specified by the destination specification process.

  In the route guidance process, map data is read from the external storage medium 18 and an image in which the calculated guidance route, destination, waypoint, current position, etc. are overlaid on the map indicated by this map data is output to the image display device 13. In this process, a guidance voice signal instructing a right turn, a left turn or the like is output to the voice circuit 14 when the host vehicle needs to arrive before the guidance intersection.

  In the above-described destination specifying process, the control circuit 19 uses the incomplete memory of the user such as the time when the vehicle has traveled in the past, the time when the vehicle passed the facility, the rough area of the facility, and the like. Based on the base information, a function for specifying the destination (hereinafter referred to as an incomplete memory search function) can be realized. For this purpose, the control circuit 19 repeatedly executes the traveling peripheral facility data recording program 100 shown in FIG. 3 when traveling (for example, when the speed of the host vehicle based on the vehicle speed sensor is zero or more), and in the destination setting process The destination setting program 200 shown in FIG. 4 is executed when the user performs an operation to the operation switch group 12 to request the realization of the incomplete memory search function. Note that the interval of repeated execution of the traveling peripheral facility data recording program 100 may be constant (for example, 1 minute), and may vary depending on various conditions such as the vehicle speed, the degree of traffic congestion on the traveling road, and whether or not the road is an urban area. Alternatively, it may vary randomly within a certain range.

  In the execution of the traveling peripheral facility data recording program 100, the control circuit 19 first identifies the current position in step 110, and then in step 120, determines the plurality of facilities around the current position from the facility data in the map data. Extract the index of.

  Here, the facility around the current position may be a facility within the first reference distance from the current position, for example. This first reference distance may be a constant value stored in advance, or a value that increases as the execution interval of the traveling peripheral facility data recording program 100 increases (for example, within 1 km if the execution interval is 1 minute), vehicle speed It may be a value that fluctuates based on various conditions, such as a value that increases as becomes larger, or may be a value that is randomly determined within a certain range.

  In addition, the facility around the current position may be, for example, a facility that is within a first reference distance from the current position and within a second reference distance from a road that is a travel route of the host vehicle. Here, the second reference distance is a distance within a range that can be visually confirmed from the road, and is a distance shorter than the first reference distance, for example, 1/5 of the first reference distance. In addition, the route as the travel route may be the guidance route as long as the route guidance along the guidance route is performed. If the route guidance along the guidance route is not performed, the host vehicle It may be a route actually traveled by then.

  In step 130, additional information related to the current position is acquired. Specifically, traffic status information such as the degree of congestion at the current location is acquired using the VICS receiver 15, and the weather information at the current location is obtained from the weather information server on the wide area network using the wireless communication circuit 10. get. In step 130, as detailed facility information, the wireless communication circuit 10 is used to acquire feature information about more facilities from a facility information server on the wide area network, and the acquired feature information is converted into facility data. In addition, an index is extracted for a facility that is known to be in the vicinity of the current position in the feature information among the acquired facilities.

  Subsequently, in step 140, based on the feature information acquired in step 120, the facility index extracted in steps 120 and 130, the current date and time, the current position, the weather at the current time of the current position, and the current time of the current position. A data entry (hereinafter referred to as a travel entry) associated with the degree of traffic congestion is created, and the travel entry is written in a writable storage medium in the external storage unit 18 as additional data of the travel peripheral facility data. After step 140, one execution of the traveling peripheral facility data recording program 100 ends.

  When the control circuit 19 repeatedly executes such a driving peripheral facility data recording program 100, the writable storage medium in the external storage unit 18 of the vehicle navigation device 1 includes the current date and time, the current position, and the current position periphery. Traveling peripheral facility data including a plurality of traveling entries including an index of a plurality of facilities, a current position, and additional information (weather, congestion degree, etc.) at the current position, and the like are recorded. FIG. 5 shows an example of such traveling peripheral facility data in a table format.

  In addition, in the execution of the destination setting program 200, the control circuit 19 first causes the image display device 13 and the audio circuit 14 to perform image and audio display for prompting the user to input the narrowing conditions in step 210, and the user operation switch It waits for the input of a narrowing condition using the group 12.

  Here, the narrowing condition categories accepted by the control circuit 19 include time, weather, congestion level, rough area, major classification type, minor classification type, and partial name.

  As a condition of time, you may specify a specific date and time, such as “○ year □ month △ day × hour”, specify only a specific date, or specify a specific week The period of the day may be specified like a specific month. Moreover, you may designate the collection of days which have specific characteristics, such as Sunday, Wednesday, and a holiday. In addition, a logical combination of conditions of multiple types, such as “all Wednesdays in May 2003”, “1st to 5th January 2005, and afternoon in December 2004”. A logical combination may be used. In other words, any condition may be used as long as it is a condition for designating the time.

  Weather conditions include sunny, rainy, typhoon, thunderstorms, and logical combinations of these. The conditions for the degree of congestion include the presence / absence of a congestion and the length of the congestion. Rough areas include prefectures, cities, towns, chome, and national highway No. 1. The rough area may be a range of the map currently displayed by the image display device 13 or specified by the user using the touch panel in the range displayed by the image display device 13. It may be an area. Major categories include leisure facilities, convenience stores, restaurants, and the like. Small classification types include pachinko shops, Chinese restaurants, parks and the like.

  The partial name means a part of the unique name of the facility. As a case where this partial name is designated as the narrowing-down condition, for example, a case where the user can remember only a part of the unique name of the facility that has traveled around in the past can be considered.

  In addition, as a narrowing-down condition, only one of a plurality of categories such as time, weather, congestion degree, rough region, major classification type, minor classification type, and partial name may be accepted. Of these categories, any combination desired by the user may be accepted.

  Subsequently, in step 220, the facility data is used to search and extract facilities that meet the received narrowing conditions from the travel peripheral facility data. Specifically, for each of all the indices of the facilities described in the traveling peripheral facility data, one or more traveling entry data having the index in the traveling peripheral facility data and the only one having the index in the facility data It is determined whether or not the feature data set of the facility entry (hereinafter referred to as comparison target data) conforms to the refinement condition, and the facility related to the entry conforms to the accepted refinement condition only if it matches. To be extracted as a facility.

  Here, if a certain comparison target data matches even one of the categories of a certain narrowing condition, it is determined that the comparison target data matches the narrowing condition. Note that the case where the comparison target data conforms to a category with a narrowing condition refers to the following case. In other words, if the category is a time designation, if any one of the dates and times included in the travel entries constituting the comparison target data is included in the designated time, the comparison target data matches the category. Further, if the category is designation of weather, if any one of the weathers included in the travel entries constituting the comparison target data matches the designated weather, the comparison target data matches the category. In addition, if the category is designated as a traffic jam level, even if one of the traffic jam levels included in the travel entries constituting the comparison target data matches the designated traffic jam level, the comparison target data conforms to the category. To do.

  In addition, if the category is a rough area specification, if even one of the location information included in the travel entries that constitute the comparison target data is included in the specified area, the comparison target data conforms to the category. To do. In addition, when the category is a rough area designation, if the location information included in the facility entry constituting the comparison target data is included in the designated area, the comparison target data is adapted to the category. It may be.

  In addition, when the category is a partial name designation, when the character string of the name information included in the facility entry constituting the comparison target data includes the character string of the designated partial name, the comparison target Data fits that category. In addition, when the category is a major classification type or a minor classification type (that is, facility type), the major classification type or minor classification type included in the facility entry constituting the comparison target data is the designated major classification type or minor classification. When the classification part is included, the comparison target data is adapted to the category.

  Subsequently, in step 230, feature data such as names and positions of a plurality of facilities extracted as a result of the search in step 220 are displayed on the image display device 13 in a selectable manner. The display that can be selected is, for example, a display on the display screen of the image display device 13 that can detect, based on a signal from the touch panel, which part of the list the user touches. Say. At this time, as the priority order of the display of the facilities, the facilities closer to the current position may be displayed more preferentially (for example, at the top of the list), or the traveling having the facility index in the traveling peripheral facility data Facilities with newer date and time data in the entry may be displayed more preferentially.

  Subsequently, in step 240, the process waits until there is an operation of the operation switch group 12 for selecting one of the displayed facilities. If there is an operation, then in step 250, based on the operation content, Identify the selected facility as the destination. After step 250, one execution of the destination setting program 200 ends.

  When the control circuit 19 executes the destination setting program 200 as described above, the vehicular navigation device 1 is able to provide facilities such as date and time, rough area, weather, congestion level, facility type, partial name, and combinations thereof. A narrowing condition that cannot uniquely identify the vehicle is received (see step 210), and based on the travel peripheral facility data and the facility data, a facility that matches the received narrowing condition is searched (see step 220), and the matching is performed. A plurality of facilities are displayed on the image display device 13 (see step 230), the user selects a facility using the display (see step 240), and the facility related to the received selection is specified as a destination (step) 250).

  As described above, the vehicular navigation apparatus 1 sequentially records the traveling peripheral facility data for specifying the facilities around the traveling route during traveling, and the facility is uniquely identified only by specifying the destination to be guided. Based on the comparison target data, the narrowing-down conditions not defined in the above are applied to the facilities in the traveling peripheral facility data. Therefore, if you want to go to a distant facility that you have visited only once in the past, but remember only the date you visited the facility and the prefecture where the facility was located, or beside the road you used to pass by. If you want to go to a fashionable store, but it ’s an Italian restaurant and you ca n’t remember anything except that it ’s a downpour, it ’s a unique location that the user has traveled to in the past. If you do not memorize the information to be used, destination setting based on information that cannot uniquely identify the facility will be realized after performing complex operations using a combination of conventional functions Compared to the case, it can be performed easily.

  In addition, since the vehicle navigation apparatus 1 receives one selection from a plurality of facilities that meet the narrowing-down conditions in specifying the destination to be guided, the destination setting that reflects the user's intention is set. It can be performed.

  In addition, when the storage medium for recording the traveling peripheral facility data is detachable from the vehicle navigation device 1, can be carried by a person, and can be attached to the plurality of vehicle navigation devices 1, The user attaches the traveling peripheral facility data created using the vehicle navigation device 1 to another vehicle navigation device having the same configuration and operation as the vehicle navigation device 1, so that the other vehicle navigation device can The same function as the vehicular navigation device 1 can be realized.

  In the above embodiment, the traveling peripheral facility data recording program 100 and the destination setting program 200 correspond to the programs in the claims.

  Further, the control circuit 19 functions as a traveling peripheral facility recording unit by executing the traveling peripheral facility data recording program 100, and functions as a condition receiving unit by executing step 210 of the destination setting program 200. By executing steps 220 to 250, it functions as a destination specifying means, by executing steps 220 and 230, it functions as a facility display control means, and by executing steps 240 and 250, it serves as a selection receiving means.

May be.

  In addition, in step 220 of the destination setting program 200, the control circuit 19 allows the comparison target data to be adapted to the category when one of the dates and times included in the travel entry is included in the designated time. However, even when one of the dates and times included in the travel entry is included that is slightly deviated from the range of the specified timing, the comparison target data may be adapted to the category.

  Further, in step 220 of the destination setting program 200, if a certain comparison target data matches even one of the categories of a certain narrowing condition, it is determined that the comparison target data matches the narrowing condition. However, the comparison target data may be determined to meet the narrowing condition only when the certain comparison target data matches all of the categories included in the narrowing condition.

  In addition, the control circuit 19 visited the shortest facility last among the corresponding facilities extracted in step 220 without receiving the user's selection operation such as the operation in step 240 of the destination setting program 200. One of the results combined with other narrowing conditions such as facilities may be used as the destination. Further, the route calculation is performed for all the facilities extracted in step 220 without receiving the user's selection operation, and a plurality of routes calculated as a result are displayed on the image display device 13. It may be like this.

  Further, the guidance for the specified destination as in the above embodiment may not be guidance along the route, for example, simple guidance only in the relative direction to the destination with respect to the direction of the host vehicle. It may be a guide that merely highlights the position of the specified tree lowland on the map.

  In addition, the navigation device does not need to have facility data in advance. For example, the navigation device may acquire facility data from a map data server on a wide area network using the wireless communication circuit 10.

  The navigation device of the present invention is not limited to the vehicle navigation device 1 as in the above-described embodiment, and may be a navigation device that can be carried by a person.
