For this reason, in the point registration system of the present invention, there are conditions for collecting a current point detection unit and a stop index indicating whether the vehicle has stopped, and collecting special point candidates based on the stop index. The collection condition establishment determination processing means for determining whether or not the condition is established, and the current location at the time when the condition for collecting the special location candidate is established, the location represented by the current location as the special location candidate, and close to each other Special point candidate recording processing means for dividing the special point candidates into groups and recording them in the recording unit, and special point candidate display processing for displaying on the display unit the name of the area that summarizes the special point candidate group as a special point candidate list Means.
The special point candidate record processing means determines whether or not there is an existing special point candidate within a predetermined range from the special point candidate when recording the special point candidate based on the current location. If there is no candidate, record the special point candidate to be recorded as belonging to the new group, and if there is an existing special point candidate, the special point candidate to be recorded is the closest existing point candidate to the special point candidate. Record so that it belongs to the same group as the special point candidate.

  According to the present invention, the point represented by the current location is set as a special point candidate, and the special point candidates that are close to each other are grouped and recorded in the recording unit, and the group of special point candidates is summarized. Since the name is displayed on the display unit as a special point candidate list, even if a detection error occurs when detecting the current location, the special point can be recognized with high accuracy and the special point can be registered with high accuracy. be able to.

  A display processing unit (not shown) of the CPU 31 performs display processing and forms various screens on the display unit 35. For example, the map display processing means of the display processing means performs map display processing, forms a map screen on the display unit 35, displays a surrounding map on the map screen, and sets the current position as the vehicle position and the direction of the vehicle. Is displayed as the vehicle direction.

  Accordingly, the driver can drive the vehicle according to the map, the vehicle position, and the vehicle direction.

  Further, when the driver operates the operation unit 34 to input a destination, a destination setting processing unit (not shown) of the CPU 31 performs a destination setting process to set the destination. Note that the departure place can be input and set as necessary. Moreover, a predetermined point can be registered as a registered point in advance, and the registered point can be set as a destination. Subsequently, when the driver operates the operation unit 34 to input a search condition, a search condition setting processing unit (not shown) of the CPU 31 performs a search condition setting process to set the search condition.

  When the destination and search conditions are set in this way, the route search processing means (not shown) of the CPU 31 performs route search processing, reads the current location, destination, search conditions, and the like from the data recording unit 16. Based on the current location, the destination, and the search data, a route from the departure point to the destination represented by the current location is searched based on the search condition, and route data representing the searched route is output. At this time, the route with the smallest total link cost assigned to each road link is set as the searched route.

  Subsequently, a guidance processing means (not shown) of the CPU 31 performs guidance processing and provides route guidance. For this purpose, the route display processing means of the guidance processing means performs route display processing, reads the route data, and displays the searched route on the map screen according to the route data. If necessary, the voice output processing means of the guidance processing means performs voice output processing, and outputs a search route by voice from the voice output unit 37 to provide route guidance.

  The information center 51 can perform a route search process. In that case, the CPU 31 transmits the current location, the destination, search conditions, and the like to the information center 51. When the information center 51 receives the current location, destination, search conditions, etc., the route search processing means (not shown) of the CPU 54 performs route search processing similar to that of the CPU 31 and reads the search data from the database 58 to obtain the current location, destination. Based on the location and the search data, a route from the departure point to the destination is searched under the search conditions, and route data representing the searched route is output. Subsequently, a transmission processing unit (not shown) of the CPU 54 performs transmission processing and transmits the route data to the navigation device 14. Therefore, in the navigation device 14, when the basic information acquisition processing means receives the route data from the information center 51, the guidance processing means performs route guidance as described above.

  And when a guidance intersection exists on the searched route, when the vehicle reaches a route guidance point in front of the guidance intersection by a predetermined distance (for example, X [m]), the intersection enlarged map display processing means of the guidance processing means Performs an enlarged map display process, forms an enlarged map in a predetermined area of the map screen, provides route guidance using the enlarged map, and displays the map, search route, and guidance around the guided intersection. When a landmark such as a facility that is a landmark at an intersection is displayed and a route search is performed in units of lanes, route guidance is performed in units of lanes, and driving lanes are displayed. Further, if necessary, the voice output processing means outputs a voice such as “This is X [m] to the left” from the voice output unit 37 and performs route guidance.

  By the way, in order to simplify the operation of the operation unit 34 when the driver sets a destination or the like, the navigation device 14 configured as described above registers a desired point in advance and reads out the registered point. It has a point registration function that makes it possible to

  The location registration function includes a home registration function for registering one location as a home, a memory location registration function for registering a plurality of desired locations as memory locations, and the like.

  In the home registration function, when a home button formed on the destination setting screen is pressed, a pre-registered home is read and set as the destination. In the memory location registration function, when a memory location button formed on the destination setting screen is pressed, previously registered memory locations are read out and displayed in a list. Therefore, when the operator selects a desired memory point among the memory points displayed in the list and presses the selection button, the selected memory point is set as the destination.

  Next, a home registration function using the navigation system as a point registration system will be described. In the present embodiment, it is possible to register a home as a special point with high use frequency by a predetermined operation, and to search for a predetermined point, for example, a route starting from the current location and destined for the home. It is like that.

  Therefore, a special spot registration processing unit (not shown) of the CPU 31 performs a special spot registration process, and the driver can register the home by operating the operation unit 34 when the map screen is displayed.

The vehicle direction is displayed as the vehicle direction. Further, the map display processing means displays a “keep home” key k1 on the map screen.

  When the driver presses the key k1, the registration procedure guidance processing means of the special location registration processing means performs registration procedure guidance processing, and forms a guidance area AR1 by pop-up as shown in FIG. 3 on the map screen. The message “Please select home registration method” is displayed in the guidance area AR1, and the key k2 “From the current location”, the key k3 “From the address”, and the key k4 “From the candidate” are displayed. To do. In the present embodiment, a first registration method for registering a home from the vicinity of the current location Pr, a second registration method for registering a home from the home address, and a home candidate created in advance, that is, a home candidate There is a third registration method for registering a home. A special point candidate is constituted by a home candidate.

  When the driver selects the first registration method and presses the key k2, the registration procedure guidance processing means displays a registration image M1 as shown in FIG. 4 on the map screen. The registration image M1 is displayed outward in the radial direction around the mark m1 for displaying the home position and the periphery of the mark m1, and is used for scrolling the map screen to adjust the home position. It consists of a plurality of arrows m2. The registration procedure guidance processing means also includes a “detail” key k5 for requesting display of a detailed map, a “wide area” key k6 for requesting display of a wide area map, The “set” key k7 and the like for determining the position are displayed. When the driver adjusts the home position by operating the arrow m2 as necessary and presses the key k7, the registration execution processing means of the special location registration processing means performs registration execution processing, The home registration is executed at the position where m1 is displayed. In this way, the home can be registered.

  When the driver selects the second registration method and presses the key k3, the registration procedure guidance processing means forms a registration procedure guidance screen as shown in FIG. An address index list is displayed in AR2, scroll buttons for scrolling and changing the index list in area AR3, introduction buttons for reading the index list in area AR4, and “ The “return” key k9 is displayed.

  Therefore, when the driver inputs and decides the home address by operating the index list, scroll buttons, and introduction buttons, the registration procedure guidance processing means registers the map screen as shown in FIG. The image M1 is displayed. After that, when the driver performs the same operation as in the first registration method, the registration execution processing means executes home registration at the position where the mark m1 is displayed. In this way, the home can be registered.

  When the driver selects the third registration method and presses the key k4, the special point candidate display processing means of the registration procedure guidance processing means performs special point candidate display processing, as shown in FIG. A special point candidate display screen is formed, a candidate list representing home candidates is displayed in area AR6 of the special point candidate display screen, a special point candidate map representing home candidates is displayed on the map in area AR7, and the third registration A key k11 “search from address” for changing from the method to the second registration method is displayed. Further, the registration procedure guidance processing means includes a mark m3 indicating the position of the home candidate, a “registration” key k12 for performing home registration, and the position of the home candidate in the special point candidate map in the area AR7. A “correction” key k13 for correction is displayed.

  Therefore, when the driver operates the candidate list and selects a predetermined candidate, a special spot candidate map corresponding to the candidate is displayed. Subsequently, when the driver presses the key k13 as necessary to correct the position of the home candidate and presses the key k12, the registration execution processing means executes home registration at the position where the mark m3 is displayed. . In this way, the home can be registered.

  By the way, when the third registration method is selected, as described above, a candidate list is displayed on the special point candidate display screen. For this reason, home candidates are collected and collected in the navigation device 14. A candidate list is automatically created based on home candidates. A special point candidate is constituted by a home candidate.

  In that case, special point candidate collection processing means (not shown) of the CPU 31 performs special point candidate collection processing and collects home candidates.

  Next, the operation of the special point candidate collection processing means will be described.

  FIG. 7 is a flowchart showing the operation of the special point candidate collection processing means in the first embodiment of the present invention, and FIG. 8 is a diagram for explaining the operation of the special point candidate recording processing means in the first embodiment of the present invention. It is.

  The stop time calculation processing means of the special point candidate collection processing means performs stop time calculation processing, and when the driver operates the accessory switch to turn it on, the time when the vehicle is stopped while the accessory switch is off That is, the stop time is calculated. Therefore, when the accessory switch is turned off by the driver, the stop time calculation processing means starts measuring time by a timer (not shown) (real type clock that measures time even when the accessory switch is off), and the accessory switch When is turned on, the time measurement ends, the time from the start to the end of time measurement is calculated as time measurement data, and the stop time is calculated based on the time measurement data. In this case, the stop time constitutes a stop index indicating whether or not the vehicle has stopped at home.

  Next, the collection condition establishment judgment processing means of the special point candidate collection processing means performs the collection condition establishment judgment processing, reads the stop time, collects the home candidate, that is, whether the collection condition is established, Judgment is made based on whether or not the stop time is a threshold (threshold) value, which is one hour or more in this embodiment. When the collection condition is not satisfied and the stop time is shorter than 1 hour, the time data discard processing unit of the special point candidate collection processing unit performs time data discard processing, discards the time data, and the collection condition is If established and the stop time is 1 hour or more, the special point candidate recording processing unit of the special point candidate collecting processing unit performs the special point candidate recording process, and when the condition for collecting home candidates is satisfied, that is, A current location when the accessory switch is turned on is read, a point represented by the current location, that is, a stop point is set as a home candidate, and the home candidate is set as a special point as a recording unit set in the RAM 32 (FIG. 1). Recording as a recording point in the candidate recording area.

  By the way, in the special point candidate recording area, home candidates are recorded as recording points, and each recording point is divided into groups adjacent to each other, and a group ID is assigned as an identifier for each group, and coordinates and The stop time and the group ID are recorded in association with each other. The group ID is assigned a larger number for the latest group.

  Therefore, when recording the home candidate, the special spot candidate recording processing means refers to the special spot candidate recording area, determines whether there is another existing recording point, and if there is no existing recording point The special spot candidate recording processing unit assigns a new group ID to the home candidate to be recorded, records the home candidate in the special spot candidate recording area, and sets it as a recording point.

  In recording the home candidate, the recording date and time are recorded as recording point data in addition to the coordinates, stop time, and group ID.

  Further, when there is an existing recording point, the recording point determination processing unit of the special point candidate collection processing unit performs a recording point determination process, and based on the coordinates, a predetermined range from the home candidate, in this embodiment Determines whether there is an existing recording point within a set range with a radius of 20 [m] or less centered on the home candidate, and if there is no existing recording point within the set range, the special point candidate recording process The means assigns a new group ID to the home candidate to be recorded, and records the home candidate in the special point candidate recording area.

  On the other hand, if there is an existing recording point within the set range, the recording point determination processing means determines whether the number of existing recording points is 1, and if the number of existing recording points is 1, The special point candidate recording processing unit assigns the same group ID as the existing recording point to the home candidate to be recorded, and records the home candidate in the special point candidate recording area. When the number of existing recording points is 2 or more, the special point candidate recording processing unit assigns the same group ID as the closest recording point to the home candidate, and sets the home candidate in the special point candidate recording area. Record. In addition, when there are a plurality of recording points having the same distance from the home candidate and different group IDs, the special point candidate recording processing means sets the home candidate to the most of the group IDs of the respective recording points. A group ID having a large number is assigned, and the home candidate is recorded in the special point candidate recording area.

  For example, in FIG. 8, when the home candidate p1 is to be recorded for the first time, since there is no existing recording point in the special spot candidate recording area, the special spot candidate recording processing means assigns the group ID-1 to the home candidate p1. And the home candidate p1 is recorded in the special point candidate recording area.

  Next, when recording the home candidate p2, there is an existing recording point (home candidate p1) in the special point candidate recording area, and the existing recording point (home candidate) is within the set range sq1 centered on the home candidate p2. Since there is p1) and the number is 1, the special point candidate recording processing unit assigns the same group ID-1 as the existing recording point (home candidate p1) to the home candidate p2, and the home candidate p2 Is recorded in the special point candidate recording area.

  Subsequently, when the home candidate p3 is to be recorded, there are existing recording points (home candidates p1, p2) in the special point candidate recording area, and existing recording points (within the set range sq2 centered on the home candidate p3) ( Since there is a home candidate p2) and the number is 1, the special point candidate recording processing unit assigns the same group ID-1 as that of the existing recording point (home candidate p2) to the home candidate p3. Candidate p3 is recorded in the special point candidate recording area.

  When the home candidate p4 is to be recorded, there are existing recording points (home candidates p1 to p3) in the special point candidate recording area, and the existing recording points (home) are within the set range sq3 centered on the home candidate p4. Since there is a candidate p2) and the number is 1, the special point candidate recording processing means assigns the same group ID-1 to the existing recording point (home candidate p2) to the home candidate p4, and the home candidate p4 is recorded in the special point candidate recording area.

  Further, when recording the home candidate p5, there are existing recording points (home candidates p1 to p4) in the special point candidate recording area, and there is no existing recording point within the set range sq4 centered on the home candidate p5. Therefore, the special spot candidate recording processing unit assigns a new group ID-2 to the home candidate p5 and records the home candidate p5 in the special spot candidate recording area.

  Subsequently, the aggregation processing means of the special point candidate collection processing means performs an aggregation process, and the number of recording points belonging to the same group in the special point candidate recording area becomes N (a predetermined number of 10 or less) or more. When waiting, when the number of recording points belonging to the same group becomes N or more, the data of home candidates is totaled. Then, the totalization processing means calculates the cumulative value of the number of stops for the recording points belonging to the same group based on the respective recording point data, and calculates the average value of the stop time for the recording points belonging to the same group. The average stop time is calculated, the average value of the coordinates for the recording points belonging to the same group is calculated as the average stop coordinate, and the special point candidate recording processing means calculates the cumulative stop count, the average stop time, and the average stop coordinate. Then, it is recorded in the special point candidate recording area as aggregated data.

  The cumulative number of stops represents the usage frequency of the recording points, the average stop time represents the usage time of the recording points, and each represents the usage rate of the recording points. The average stop time and the average stop coordinate are obtained by dividing the sum of the stop times and the sum of the stop coordinates by the cumulative number of stops.

  Next, the totalization processing unit rearranges the recording point data of the recording points belonging to each group in the order of recording date and time (for example, the oldest order of the recording point data).

  In this way, for example, a maximum of Ma groups, in this embodiment, a maximum of Mb recording points for 100 groups, and a maximum of 10 recording points in this embodiment are recorded. However, when the number of recording points in a predetermined group reaches Mb, the tabulation processing means deletes the recording points within a maximum range of Mb / 2.

  Thus, each home candidate can be collected and recorded in the special point candidate recording area. In the present embodiment, the home candidates that are close to each other are divided into groups, group IDs are assigned, and stop points are averaged by calculating average stop coordinates. When the present location is detected by the sensor 15, a detection error of several meters to several tens of meters occurs, and the present location cannot be accurately specified in the matching process, and although it is actually stopped at the same point, Even if it is determined that the vehicle has stopped at a different point, the home can be recognized with high accuracy, and the home can be registered with high accuracy.

Next, a flowchart will be described.
Step S1: Waiting for the accessory switch to be turned on, and when the accessory switch is turned on, the process proceeds to step S2.
Step S2: The stop time is calculated based on the time measurement data.
Step S3: It is determined whether or not the stop time is 1 hour or longer. If the stop time is 1 hour or longer, the process proceeds to step S5. If the stop time is not 1 hour or longer, the process proceeds to step S4.
Step S4: The timing data is discarded and the process is terminated.
Step S5: Determine whether there is an existing recording point. If there is an existing recording point, the process proceeds to step S6, and if not, the process proceeds to step S7.
Step S6: Determine whether there is an existing recording point within the set range. If there is an existing recording point within the set range, the process proceeds to step S8, and if not, the process proceeds to step S7.
Step S7: A new group ID is assigned and recorded, and the process is terminated.
Step S8: It is determined whether or not the number of existing recording points is one. If the number of existing recording points is 1, the process proceeds to step S10. If not, the process proceeds to step S9.
Step S9 The process waits for the number of recording points belonging to the same group to be N or more.
Step S10: The same group ID is assigned and recorded, and the process is terminated.
Step S11: Aggregation processing is performed.
Step S12: The recording point data of each group ID is rearranged in order of recording date.
Step S13: Recording points are deleted within the maximum Mb / 2 range, and the process is terminated.

  Subsequently, the special spot candidate display processing means displays each home candidate as a candidate list on a special spot candidate display screen as shown in FIG.

  Next, the operation of the special point candidate display processing means will be described.

  FIG. 9 is a flowchart showing the operation of the special point candidate display processing means in the first embodiment of the present invention. In this case, let each group be Gi (i = 1, 2,...).

  First, the cost calculation processing means of the special point candidate display processing means performs cost calculation processing, and displays a candidate list depending on whether the driver selects the third registration method and presses the key k4 (FIG. 3). , That is, if there is a candidate list display request, for each group Gi, a cost Cti (i = 1, 2,...) Indicating the possibility that the home candidate is home. ) Is calculated. In this case, the cost Cti is decreased as the possibility that the home candidate is home is increased, and is increased as the possibility that the home candidate is home is decreased.

For this purpose, the first cost index value calculation processing means of the cost calculation processing means performs a first cost index value calculation process, reads the cumulative stop count for each group Gi from the special point candidate recording area, When the groups Gi are arranged in descending order of the number of stops, the value representing the rank of each group Gi is ηi (i = 1, 2,...), And the coefficient is α1, the first for each group Gi. Cost index value fi (i = 1, 2,...)
fi = α1 · ηi
Is calculated. Note that a first cost evaluation value for calculating the cost Cti is configured by the cumulative number of stops.

Subsequently, the second cost index value calculation processing means of the cost calculation processing means performs a second cost index value calculation process, reads an average stop time for each group Gi from the special point candidate recording area, and calculates the average When the groups Gi are arranged in order of long stop time, the value representing the rank of each group Gi is εi (i = 1, 2,...), And the coefficient is α2, the second for each group Gi. Cost index value gi (i = 1, 2,...)
gi = α2 · εi
Is calculated. The average stop time constitutes a second cost evaluation value when calculating the cost Cti.

The total cost calculation processing means of the cost calculation processing means performs a total cost calculation process, adds the first and second cost index values fi and gi, and calculates the cost Cti.
Cti = fi + gi
= Α1 ・ ηi + α2 ・ εi
Is calculated.

In the present embodiment, the coefficient α1 is set to 1 in order to increase the possibility that the home candidate is home when the cumulative number of stoppages is large, and to increase the possibility that the home candidate is home when the average stop time is long. And the coefficient α2 is 2,
α1 <α2
I made it.

  Then, the cost calculation processing means determines whether there is a group with the same cost Cti. If there is a group with the same cost Cti, the cost Cti of the group with the newest recording date is changed and made smaller.

  Subsequently, the group display processing means of the special spot candidate display processing means performs group display processing, and determines the ranking of home candidates to be displayed based on the rank of the cost Cti. Then, the names of the home candidates represented by the group Gi are displayed in the order of decreasing cost Cti in the area AR6 of the special spot candidate display screen shown in FIG. Note that the name of the home candidate is represented by the name of an area that summarizes the respective recording points belonging to the group Gi, such as “near XX town XX address”.

  In this way, when a predetermined home candidate is selected from the home candidates displayed in the area AR6, the special point registration processing means records the coordinates of the point where the selected home candidate exists as the home. Therefore, after that, when the driver presses the home button on the destination setting screen, the destination setting processing means sets the home as the destination.

  Thus, in the present embodiment, as the cumulative number of stops increases and the average stop time increases, the cost Cti is reduced and the possibility that the home candidate is home is increased. Less frequent stop points are recognized as homes. Therefore, the home can be recognized with high accuracy, and the home can be registered with high accuracy.

  For example, a point with a low average number of stoppages, such as a point where you went to play once, is excluded from your home candidate, or a point where the average stop time is short, such as a stop at a supermarket or a gas station. And can be excluded from the candidates.

  In the present embodiment, it is determined whether or not there is a request for displaying the candidate list, and if there is a request for displaying the candidate list, the cost Cti is calculated. In calculating the cost Cti, a predetermined calculation is performed. Conditions can be set. In this case, the cost calculation processing means reads the number of recording points recorded in the special point candidate recording area for each group Gi, and the calculation condition is satisfied depending on whether or not the number of recording points exceeds a predetermined value. Determine if you did. When the calculation condition is satisfied, the cost calculation processing means calculates the cost Cti.

Next, a flowchart will be described.
Step S21 The system waits for a candidate list display request. If there is a candidate list display request, the process proceeds to step S22.
Step S22: Calculate a first cost index value fi.
Step S23: The second cost index value gi is calculated.
Step S24: Calculate the cost Cti.
Step S25: It is determined whether there is a group having the same cost Cti. If there is a group with the same cost Cti, the process proceeds to step S26, and if not, the process proceeds to step S27.
Step S26: The cost Cti of the group with the newest recording date is reduced.
Step S27 The names of the home candidates are displayed in ascending order of the cost Cti, and the process ends.

  By the way, in the present embodiment, the special point registration processing means can register the home when the map screen is displayed, but the driver turns on the accessory switch to perform navigation. The home can also be registered when the device 14 (FIG. 1) is activated.

  Next, a description will be given of a second embodiment of the present invention in which a home can be registered when the navigation device 14 is activated.

  FIG. 10 is a diagram showing an example of a registration procedure guidance screen in the second embodiment of the present invention.

  In this case, when the driver turns on the accessory switch as the activation switch, the navigation device 14 (FIG. 1) is activated, and accordingly, the registration procedure guidance processing means performs the registration procedure as shown in FIG. Create a guidance screen and display the message “Notification”, “Would you like to register at home?” And “You can search the route to your home with simple operations” on the registration procedure guidance screen. At the same time, a key k22 “from the vicinity of the current location”, a key k23 “from the address”, a key k24 “from the candidate”, and a key k25 “do not display next time” are displayed. In the present embodiment, as in the first embodiment, a first registration method for registering a home from the vicinity of the current location Pr (FIG. 2), a second registration method for registering a home from a home address, And a third registration method for registering the home from the home candidates.

  When the driver selects the first registration method and presses the key k22, the map screen as shown in FIG. 4 shows the map screen as shown in FIG. 4 when the second registration method is selected and the key k23 is pressed, as shown in FIG. When the registration procedure guidance screen as described above selects the third registration method and presses the key k24, a special point candidate display screen as shown in FIG. 6 is formed. Therefore, when the driver thereafter performs the same operation as in the first embodiment, the home can be registered.

  Next, a third embodiment of the present invention will be described in which the home can be registered when the driver inputs the destination.

  FIG. 11 is a first diagram showing an example of a destination input screen according to the third embodiment of the present invention, and FIG. 12 is a second diagram showing an example of the destination input screen according to the third embodiment of the present invention. FIG.

  In this case, when the driver operates the operation unit 34 (FIG. 1) as the first input unit to instruct the input of the destination, the destination setting processing means performs the destination input as shown in FIG. Then, the registration procedure guidance processing means forms a pop-up guidance area AR21 as shown in FIG. 12 on the destination input screen, and the home area is registered in the guidance area AR21. “No” and “Display registration screen” messages are displayed, and then a registration procedure guidance screen as shown in FIG. 5 is formed, or a special point candidate display screen as shown in FIG. Form.

  In each of the above embodiments, whether or not the collection condition of the home candidate is satisfied is determined based on whether or not the stop time as the stop index is 1 hour or longer. It is also possible to determine that the collection condition is satisfied when is satisfied.

  For example, the collection condition establishment judgment processing means compares the current location when the accessory switch as the activation switch is turned off with the current location when the accessory switch is turned on, and determines whether the collection condition is established. It can be judged by whether or not both current locations are the same. In this case, a stop index is constituted by both current locations. For example, when the vehicle is moved with the engine stopped, such as when the vehicle is transported by a ferry, the current location when the accessory switch is turned off, and when the accessory switch is turned on. Since it is different from the current location, even if the stop time is one hour or longer, it can be prevented from being recorded as a home candidate.

  In addition, when the driver works in the daytime, whether or not the collection condition is satisfied is judged by whether or not the time when the accessory switch as the stop index is turned off is at night, or as the stop index Judgment can be made based on whether or not the stop time crosses the day. Then, when the vehicle is moved backward to enter the parking lot and moved forward to exit the parking lot, whether the collection condition is satisfied is determined by whether the accessory switch is turned off after the reverse gear is used. be able to. In this case, the stop index is constituted by the signal of the accessory switch.

  When morning commuting by a vehicle is regularly performed, whether the collection condition is satisfied is determined by whether the time when the accessory switch as the stop index is turned on falls within a certain time. be able to.

  Further, in the present embodiment, the recording point determination processing means determines whether or not there is an existing recording point within a set range having a radius centered on the home candidate of 20 [m] or less from the home candidate. When there is an existing recording point within the set range, the special point candidate recording processing means assigns the same group ID as the existing recording point to the home candidate, and records the home candidate in the special point candidate recording area. However, if there is an existing recording point within the set range, the home candidate can be regarded as the same point as the existing recording point, and an intermediate point of the line connecting the two points can be recorded as the recording point. In this case, the possibility that the home candidate is greatly shifted from the existing recording point is reduced.

  Further, the recording point determination processing means determines whether the address of the home candidate belongs to the same address as the existing recording point, and if the address belongs to the same address, the special point candidate recording processing means The same group ID as the recording point can be assigned, and the home candidate can be recorded in the special point candidate recording area.

  In the present embodiment, the cost Cti is reduced when the cumulative stop count is large and the average stop time is long, but the cumulative stop time that represents the cumulative value of the stop time is calculated, When the accumulated stop time is long, the cost Cti can be reduced.

  In addition, before the vehicle is delivered to the driver who is the user, the timing at which the special point candidate collection process is started is set, for example, after the route search is first performed so that the home candidate is not collected. Is done. In addition, after the home is registered, the special point candidate collection processing function is stopped, and each recording point data, total data, and the like are deleted.

  In this embodiment, the home is registered as a special point, but a few places such as frequently used offices, relatives' homes, and parking lots around the station are selected and registered as special memory points. The special memory point can be registered as a special point.

  In addition, this invention is not limited to the said embodiment, It can change variously based on the meaning of this invention, and does not exclude them from the scope of the present invention.
