Description

  The present invention relates to an apparatus for accumulating movement history in a moving body such as a vehicle, and more particularly to an apparatus for accumulating movement history for each driver (user).

  Conventionally, as a first conventional technique for accumulating a movement history in a moving body such as a vehicle, a car that accumulates a movement history, predicts a destination using the movement history, and estimates a required time to the destination. A navigation system has been proposed (see, for example, Patent Document 1). This system discloses a technique for accumulating a movement history for each driver by inserting an IC card or the like to identify who the user is during driving.

  In addition, as a second conventional technique, in order to avoid the privacy problem of each driver's movement history, the movement history cannot be browsed unless the driver's ID is input. Has been disclosed (see, for example, Patent Document 2). Also in this system, the driver is identified by holding the IC card or storing the user ID.

Furthermore, as a third prior art, in accumulating the movement history, the movement history is automatically edited using the time during which the engine has been stopped in order to delete the place where the user stopped in the middle from the movement history. A technique is disclosed (for example, see Patent Document 3).
JP 11-149596 A JP 2000-193474 A JP 2000-205869 A

  However, in the first and second prior arts described above, it is necessary to insert an IC card and input a user ID in order to determine who the driver is. For this reason, there are inconveniences that the vehicle cannot be driven without bringing an IC card (movement history cannot be accumulated) and that the movement history cannot be searched or registered if the user ID is forgotten. . Further, since all the movement histories are accumulated, there is also a disadvantage that the movement histories that the driver does not want to register are registered. As a result, there arises a problem that the travel history cannot be utilized in a business vehicle that provides privacy according to the problem of privacy and the distance of the travel history.

  In the third prior art, although the movement history is automatically edited, there is no function for automatically deleting / editing the history that the driver does not want to leave as the movement history.

  Therefore, the present invention has been made in view of such problems, and provides a movement history storage device and method for storing a movement history for each user without inputting who the driver is. For the purpose.

  It is another object of the present invention to provide a movement history storage apparatus and method that can prevent a history that the driver does not want to leave as a movement history from being registered.

  In order to achieve the above object, a first movement history accumulation device according to the present invention is an apparatus for accumulating movement histories of a moving body, and accumulates the movement history of the moving body for each user who drives the moving body. Movement history accumulating means, movement history temporary accumulating means for temporarily accumulating the movement history of the moving object when the moving object is moving, and movement history accumulated in the movement history temporary accumulating means A user identification unit that identifies a user related to the movement history accumulated in the movement history temporary accumulation unit by comparing the movement history for each user accumulated in the movement history accumulation unit, and A movement history storage means for storing the movement history stored in the movement history temporary storage means as the movement history is stored in the movement history storage means. As a result, the driver of the moving body is automatically determined, and the movement history is accumulated for each driver, so that it is not necessary to input who the driver is.

  Here, the user specifying means specifies and specifies a movement history most similar to the movement history stored in the movement history temporary storage means from the movement history for each user stored in the movement history storage means. The user corresponding to the travel history may be identified as the user. The movement history is expressed as a series of intersections of roads through which the moving body has passed, and the user specifying means stores the intersection in the movement history accumulated in the movement history temporary accumulation means in the movement history accumulation means. The user may be specified based on the probability for each user determined from the frequency of matching the intersection in the accumulated movement history for each user. At this time, for example, the series of intersections is preferably expressed by a series of intersection information specifying the intersections or a collection of link information indicating two consecutive intersections.

  Further, the movement history temporary storage means repeats specifying the position of the moving body at a constant time interval, and when there is an intersection on a series of the specified positions, the movement history temporary storage means is described as an intersection passing through the intersection. The movement history may be accumulated. As a result, even when two passing points that have jumped over the intersection are detected, such as when the moving object passes through the intersection at high speed, it is recognized as having passed through the intersection existing between them. The movement history is surely created as a series.

  The movement history temporary storage means acquires road information at that time, determines whether or not the accumulated movement history and the movement history accumulated in the movement history accumulation means are similar, and the road information Indicates predetermined information and the movement histories are similar, the movement histories temporarily accumulated as the same contents may be accumulated in the movement history accumulation means. As a result, even when the vehicle is temporarily detoured due to road construction or traffic congestion, it is possible to avoid the accumulation of the same travel history and the recording of an exceptional travel route.

  Further, the movement history storage means further stores at least one information of a time zone and a day of the week related to the movement history of the mobile body, and the movement history temporary storage means stores the time zone and the day of the week related to the movement history. At least one piece of information is added to and stored in the movement history, and the user specifying means stores, in addition to the movement history, at least one of a time zone and a day of the week in the movement history in the movement history temporary storage means. The user may be specified by combining the frequency at which the stored information matches the information for each user stored in the movement history storage unit. As a result, not only the movement history but also the identity of the time zone and day of the week are taken into account, so that the user can be identified more reliably.

  Further, the movement history storage device further searches the movement history stored in the movement history storage means for a movement history satisfying a certain condition for a user movement history specified by the user specifying means. Means may be provided. This makes it possible to search for movement histories on the condition that the same user is used, making it easy to refer to past movement histories when equipped in a car navigation device or the like, and improving convenience.

  In order to achieve the above object, the second movement history storage device according to the present invention further includes an operation in which the movement history storage device further stores an operation history of a device mounted on a moving body for each user. A history storage means, and an operation history temporary storage means for temporarily storing the operation when the user operates the device, wherein the user specifying means includes the movement history comparison, By comparing the operation history stored in the operation history temporary storage unit with the operation history for each user stored in the operation history storage unit, the user related to the movement history is specified. Here, the device is, for example, a device that reproduces music content, the operation history is a history of operations related to the reproduction of music, and the user specifying unit is an operation stored in the operation history temporary storage unit. For the history, the user is identified based on the probability for each user determined from the frequency that matches the operation history for each user stored in the operation history storage means. As a result, not only the movement history but also the operation history of the in-vehicle device is taken into account, so that the user can be specified.

  In order to achieve the above object, in the third movement history storage device according to the present invention, the user specifying means further stores the movement history stored in the movement history temporary storage means and the movement history storage means. By comparing the movement history for each user, the history mismatch degree indicating the degree of non-coincidence with the movement history of any registered user is calculated, and the movement history storage device further includes: When the calculated history mismatch degree exceeds a certain threshold value, a contact means for notifying a predetermined notification to the owner of the mobile body is provided. As a result, it is automatically detected that a driver other than the driver registered in advance is driving the moving body, and the owner is notified, so for example, it is possible to find a car theft. .

  Here, the movement history storage device further includes owner position detection means for detecting the position of the owner of the mobile object, and the communication means is configured such that the detected owner position is constant from the position of the mobile object. It is preferable that the notification is made when it is within a range and the history mismatch degree exceeds a certain threshold. As a result, even when the driver travels on a route different from the travel history so far, it is determined whether or not the vehicle is driven by the owner, so that it is avoided that the driver is erroneously recognized as theft. .

  In addition, the same thing can be achieved by calculating the history mismatch degree after the user specifying means compares the movement histories excluding a predetermined area set in advance.

  In order to achieve the above object, a fourth movement history storage device according to the present invention further includes a history rejection storage in which the movement history storage device further stores, as a history rejection region, a region that is not to store a movement history. The movement history storage means determines whether or not the movement history stored in the movement history temporary storage means corresponds to a history rejection area stored in the history rejection storage means. The movement history is not stored in the movement history storage means.

  Here, for example, the history rejection storage unit specifies the area in accordance with a user instruction, and stores the specified area as the history rejection area. The movement history storage means, for example, excludes movement history in movement within a certain range from the history rejection area stored in the history rejection storage means, out of the movement history accumulated in the movement history temporary storage means. Thus, the movement history is stored in the movement history storage means. As a result, accumulation of movement history and movement points that the user does not want is avoided, and user privacy is protected.

  In order to achieve the above object, another movement history storage apparatus according to the present invention is further provided, wherein the movement history storage apparatus further includes a history deletion request input means for receiving an input of a request to delete the movement history. Based on the request, from the movement history stored in the movement history storage means, a deletion movement history selection means for selecting a movement history to be deleted, and a movement history change means for deleting all or a part of the selected movement history; It is characterized by providing. As a result, a part of the movement history can be deleted from the viewpoint of privacy protection and the like.

  Here, the movement history storage device further detects a common intersection or road before and after the request point input by the history deletion request input means from the movement history selected by the deletion movement history selection means, A deletion section detection unit that deletes a section between the intersection or the road may be included, and the movement history change unit may delete the deletion section in the movement history and store the deletion section in the movement history storage unit. . As a result, it is possible to delete the section from the intersection as the starting point until returning to the same intersection again, so that the continuity of the route in the movement history after the deletion is maintained.

  The movement history storage device further changes the time information or the position information of the movement history according to the section detected by the deletion section detection means for the movement history in which the deletion section is deleted by the movement history change means. It is preferable to include time position information changing means for performing. As a result, the movement time and position information at other points are changed along with the deletion of a part of the movement history, and not only the route but also the time information is maintained, and the departure time and arrival time are maintained. Therefore, it is avoided that unnaturalness remains in the edited movement history, and it becomes difficult for others to detect that the movement history has been edited, and privacy is protected.

  In order to achieve the above object, another movement history storage device according to the present invention is configured such that the movement history storage device further stores the section detected by the deletion section detection means and the movement history storage means. According to the present invention, there is provided a movement history generating means for generating a substitute movement history according to the movement history. The movement history changing means substitutes a movement history instead of the movement history to be deleted using the movement history accumulated in the movement history accumulation means. As a result, the part of the deleted movement history is replaced with another movement history, so that the time information and position information in the part that has not been deleted are maintained as they are, and the desired movement history can be edited naturally. It becomes possible.

  Here, the movement history changing means may select a substitute movement history from the movement history accumulated in the movement history accumulation means by using the transit point information or time information of the movement history, The movement history change means may select a movement history of the user who can refer to the movement history as a substitute movement history. This makes it possible to create a new movement history by combining two or more movement histories, or to select a movement history to substitute from those who browse the movement history, for purposes such as protecting privacy. A natural movement history can be generated.

  Note that the present invention can be realized not only as the above-described movement history storage device but also as a movement history storage method using characteristic components constituting the movement history storage device as a step. It can also be realized as a program to be executed. Needless to say, such a program can be distributed via a transmission medium such as the Internet or a recording medium such as a CD-ROM.

  According to the present invention, it is possible to accumulate a movement history for each user without inputting who the driver is. Further, when the vehicle heads in a direction that is not always directed due to theft of the vehicle or the like, it is automatically determined that the vehicle is stolen and the vehicle owner can be notified.

(Embodiment 1)
FIG. 1 is a functional block diagram showing an overall configuration of a movement history storage device 100 according to Embodiment 1 of the present invention. The movement history storage device 100 is a device that identifies a driver based on the movement history and stores the movement history. The movement history temporary storage unit 101, the driver-specific movement history storage unit 102, and the driver-specific history comparison The unit 103 includes a driver-specific movement history transfer unit 104 and a history search unit 105.

  The movement history temporary storage unit 101 is a processing unit including a memory or the like that temporarily stores the movement history of the vehicle. The movement history accumulating unit 102 for each driver is a storage unit such as a hard disk for accumulating the movement history for each driver. The driver-specific history comparison unit 103 compares the movement history accumulated in the movement history temporary accumulation unit 101 with the movement history accumulated in the driver-specific movement history accumulation unit 102 to determine the driver. It is. The driver-specific movement history transfer unit 104 transfers the movement history accumulated in the movement history temporary storage unit 101 by the driver obtained by the driver-specific history comparison unit 103 to the driver-specific movement history storage unit 102. Part. The history search unit 105 is a processing unit that searches the movement history accumulated in the driver-specific movement history accumulation unit 102.

  FIG. 2 is a diagram showing a hardware configuration of a car navigation system provided with the movement history storage device 100. In FIG. 2, a display 201 is an LCD or the like that displays a car navigation screen. The GPS sensor 202 is a GPS sensor for acquiring the current position. The car navigation body 203 is a car navigation device in which map data such as a hard disk and a DVD is stored.

  The operation of the car navigation system configured as described above will be described. In the present invention, when a sufficient amount of movement history data has been accumulated in advance for each user, it is automatically determined which driver the movement history is for the acquisition of new movement history data. Judgment. Further, the movement history data obtained from the driver needs to express latitude / longitude data obtained from the GPS in a series of predefined intersections. Therefore, a method for converting the latitude / longitude position information series into the intersection series will be described first with reference to the flowchart of FIG.

  In order to convert the latitude / longitude data series into the intersection series, the correspondence between the road ID in FIG. 4 and its position information and intersection information, and the road and intersection shown in FIG. The relationship table is necessary in advance. In FIG. 4, Route 1 (R0001) passes through points of each position (latitude / longitude), and 34 degrees 44 minutes 35.22 seconds and 135 degrees 20 minutes 37.01 seconds indicate the intersection. ing. In FIG. 5, information regarding each intersection is described, and position information of the intersection and the route on which the intersection is located are shown. For example, the intersection C2034 indicates that the intersection passes through R001 and R002.

  Next, a method for detecting an intersection where a vehicle has passed from information on the current location using the tables of FIGS. 4 and 5, that is, a method for temporarily storing a movement history by the movement history temporary storage unit 101 is shown in FIG. 3. This will be described with reference to a flowchart.

First, current position data is acquired from the GPS (step 301).
Subsequently, the distance between the GPS data acquired in step 301 and the data of each point of the road shown in the table of FIG. 4 is calculated, and the closest road is selected (step 302).

  Then, it is determined whether or not the road selected in step 302 is the same road as the road selected immediately before (step 303). For example, in FIG. 6, the closest road from the previous GPS data is Route 1 (R0001) and the corresponding point of P2 is calculated, and the closest road from the current GPS data is the corresponding point of P3 of Route 1 Suppose that At this time, since both are the same roads on Route 1, the process proceeds to Step 304.

  Further, it is determined whether or not the vehicle passes an intersection on the road (step 304). In FIG. 6, it can be seen that there is an intersection C1021 during the movement from P2 to P3 on Route 1. In FIG. 4, since each road is represented by a series of position data, it can be extracted from the context. In this case, the process proceeds to step 305.

  Since it is predicted that the vehicle has passed the intersection of C1021 when moving from P2 to P3, C1021 is registered as passing intersection data (step 306).

  Finally, it is determined whether or not the vehicle has stopped (step 307). If the vehicle has stopped, the flow ends.

  Here, a case will be described where, in step 303, the previously selected road is different from the currently selected road. For example, in FIG. 6, it is assumed that P5 of Route 1 (R0001) is selected as the closest road from the previous GPS data, and P6 of Route 2 (R0002) is selected as the closest road from the current GPS data. At this time, since route 1 and route 2 are different roads, the process proceeds to step 305.

  Then, since it can be seen that the route is moving from Route 1 to Route 2, it can be seen that the vehicle has passed the intersection C2034, and this intersection is registered as a transit intersection (step 305). In FIG. 5, since the information of the intersection which crosses between routes is accumulate | stored, it is possible to select the intersection which goes through easily.

  With the above flow, the GPS series data obtained from the user can be easily converted into the intersection series data. In this embodiment, the movement history of each user is expressed by this intersection series. , It shall be accumulated.

  In the above-described embodiment, an example has been described in which, when the route on which the user is traveling is different, it is determined that the route passes through an intersection between the routes and is accumulated as movement history information. On the other hand, when a user travels at a high speed on a road where the distance between intersections is short in the city center or the like, there is a case where it is not accumulated as a history even though the intersection is actually a passing intersection. For example, if the vehicle is traveling at a speed of 60 km / h, it will move about 17 m per second. At this time, if the GPS position data acquisition interval is in units of 1 second, it may not be stored as a transit intersection when the distance between the intersections is within 17 m. Therefore, as shown in FIG. 7, even if GPS position information is not detected between C1019 and C1020 when traveling on Route 1 consisting of C1018, C1019, C1020, C1021,. When GPS information is detected between C1019 and GPS information is detected between C1020 and C1021, it is stored as an intersection via C1019 and C1020.

  Further, in the above embodiment, the transit intersection is accumulated as a movement history, but link information between the intersections may be accumulated. As shown in FIG. 8, a road is expressed as link information by a start point intersection and an end point intersection. In FIG. 8, for example, the link information L101 is expressed by a start point intersection C1018 and an end point intersection C1019. In this way, by expressing road information with links between intersections, each road can be expressed as a set of links connected as shown in FIG. Thus, in the above-described embodiment, the history of travel by the user is expressed as a series of intersections, but can be expressed as a series of links. Even in this case, when the vehicle is traveling at a high speed, a link with a short distance may be skipped due to the sampling interval of the GPS sensor, but by a method similar to the method of determining the intersection series described above, It is possible to reliably accumulate the links that have passed through.

  Next, referring to FIG. 10, a method for comparing the intersection series data obtained from the user with the intersection movement series stored in advance for each user, that is, the history comparison by the driver-specific history comparison unit 103. The method will be described. For each user, the accumulated intersection series data, that is, the series data accumulated in the driver-specific movement history accumulation unit 102 is data as shown in FIG. In FIG. 11, the history of movement of a plurality of drivers so far is converted into intersection series information. The driver inputs who the driver is as shown in the car navigation screen of FIG. 2 before starting driving or after driving. Then, when this movement history data is sufficiently accumulated (for example, the driving time for each driver is 50 hours or more, the driving distance is 100 km or more, etc.), the driver is automatically recognized using the movement history. Is. In FIG. 11, the first line shows that a certain user A departs at 9: 3: 23 on July 1, 2003, passes through the intersections IDC2123, C2124, C2234, and arrives at the end at 9:52. It indicates that it has reached 3 minutes. Such a movement history related to the user A is first accumulated by the user manually performing screen input or the like.

  From the movement history data accumulated as shown in FIG. 11, as shown in FIG. 12, the number of times of passing through the intersection is calculated for each driver, and the ratio to the number of times of passing through the intersection of all drivers is calculated. . The result is shown in FIG. This result is constructed in advance, and the driver is identified using the flowchart of FIG.

  From the GPS current position data, it is determined using the flowchart of FIG. 3 whether or not the driver has passed the intersection (step 701). If it has not passed, the position data is acquired again by GPS after movement. If the vehicle has passed, the passing intersection is registered as shown in FIG. FIG. 13 shows a table when passing through C1123 and C2342. If the vehicle has passed through a new intersection, the process proceeds to step 702.

It is calculated whether or not the driver can be identified (the history of each driver and the degree of coincidence) using the intersection where the driver has passed (step 702). Here, as a calculation formula for specifying the driver, determination is made using the frequency ratio of the passing intersection shown in FIG. Specifically, for example, if it is determined that the vehicle has passed the intersection of C1123, it is determined that the user A is 63%, the user B is 21%, and the user C is 16%. Again, in (Step 701), if it is found that the intersection of C2342 is passed, the average of the probability of passing the intersection of C1123 is calculated, and the probability of user A is
(63 + 9) / 2 = 36%
And go down.

  It is determined whether or not the probability for each user calculated in step 702 exceeds a predetermined threshold (for example, 70%) (step 703), and when it exceeds, the process proceeds to step 704. If the threshold is not exceeded, the process returns to step 701 again.

  Data relating to the intersection that has passed so far is registered as the movement history of the identified user (step 704).

  Thereafter, every time a passing intersection is detected (step 705), the driver-specific movement history transfer unit 104 registers the data of the intersection in the driver-specific movement history storage unit 102 as each driver's movement history ( Step 706). Further, the passing intersection until the vehicle is stopped (step 707) is registered in the movement history accumulating unit 102 by driver in the format as shown in FIG. 11, and finally the end point and its time are registered.

  With the above configuration, it is possible to automatically identify the driver from the past movement history and automatically accumulate it as a history for each driver without input by the driver.

  Note that the calculation of the probability is not limited to the method using an average value, and an addition value may be used simply. That is, the probability may be added every time an intersection is passed, and the obtained probability may be compared with a threshold value.

  In the present embodiment, as shown in step 702, the frequency information of each intersection is calculated in advance with a probability, and the driver is identified using the value. However, it is also possible to specify the driver with the frequency information of each intersection and the frequency related to the route using a plurality of intersections. For example, as shown in FIG. 14, the frequency can be calculated and the driver can be specified by using information of a series of a plurality of intersections. Although FIG. 14 is a table for the connection of two intersections, the frequency can be calculated in the same manner for a series of three or more intersections. Alternatively, the driver may be specified using the number of times of traveling that includes the intersection series.

  In the present embodiment, as shown in step 702, the frequency information of each intersection is calculated in advance with a probability, and the driver is identified using the value. However, it is also possible to specify the driver using the time zone during which each driver drove. For example, as shown in FIG. 15, frequency information indicating which driver was driving in each time zone is used, and the driver can be specified using the frequency. For example, for work, it is possible to specify that the father is driving in the morning and evening, and the mother is driving in the daytime shopping.

  In the present embodiment, as shown in step 702, the frequency information of each intersection is calculated in advance with a probability, and the driver is identified using the value. However, the driver can also be identified using the frequency of the day of the week driving. For example, as shown in FIG. 16, it is possible to determine from the past driving history a discrimination means such as a father driving many on weekdays and a mother driving many on holidays.

  Also, by combining the information shown in FIGS. 12, 14, 15, and 16 to identify the driver, it is possible to identify the driver with higher accuracy than when determining with a single table. .

  Moreover, in this Embodiment, after specifying a driver | operator, the process which registers a driving history automatically was described. However, if there is not enough information to identify the driver, the driver can be inquired. In this case, it is possible to make an inquiry with a YES / NO question “is the driver a father” instead of “who is the driver”?

  Next, as shown in FIG. 11, a method for searching for a movement history when the movement history for each driver is accumulated in a series of intersections, that is, a search function by the history search unit 105 will be described. An example of a screen for the driver to search for a movement history is shown in FIG. FIG. 17 is an example displayed on the car navigation screen. When the current location of the vehicle can be obtained, you can search for when and where you passed through the current location, and where you were headed by using the menu button "Previous history that passed here" . As a result, the driver can check the degree of congestion when he / she has passed before, and can refer to the road to be advanced from now on. In addition, with the “Previous Directions” menu button, the destination has been decided, and the route to the destination can be searched for in the previous driving history, and by confirming that information, the future route can be determined. It is possible to help. In “search by date”, the movement history of the driver can be searched by date, and the driver can easily search the travel history of last month. As a result, the user's own movement history can be totaled and confirmed.

  When the current location information is input by the driver, a method of searching a history in which a series of intersections is accumulated as shown in FIG. 11, that is, a search process by the history search unit 105 is used with reference to the flowchart of FIG. 18 and FIG. I will explain.

  First, current position data is acquired from a GPS sensor. Assume that x in FIG. 19 is acquired (step 1501).

  Subsequently, the distance between the GPS data acquired in step 1501 and the data of each point of the road shown in the table of FIG. 4 is calculated, and the nearest road is selected (step 1502). As a result, p is selected in FIG.

  Then, an intersection closest to the position of the intersection on the road in FIG. 4 is calculated (step 1503). As a result, C1021 is selected in FIG. Note that an intersection in the moving direction may be preferentially selected in consideration of the moving direction of the vehicle.

  Subsequently, it is searched whether or not the determined intersection exists in the series of intersections in the driver's movement history (step 1504). Since C1021 is not registered as an intersection of the user's movement history series, the process proceeds to step 1508.

  Again, an intersection closest to C1021 at the intersection on the road in FIG. 4 is selected (step 1508). In this case, C2034 is selected.

  Again, it is searched whether or not the intersection C2034 is registered as an intersection in the movement history (step 1504). As a result, since it has been registered, the process proceeds to step 1505.

  Then, the number of times registered as an intersection of the movement history is calculated (step 1505). As a result, since there are a plurality of times, the process proceeds to Step 1507.

  The history selected in step 1505 is rearranged in time order (step 1507), and the process proceeds to step 1506. Here, the time is sorted in the order of date and time, but the time information may be used to sort in the order closer to the current time.

  As a result, it can be displayed as shown in FIG. 20B (step 1506). In the display of FIG. 20B, the starting point and the ending point are registered in advance by the user, and “Home”, “Nagano (Parents)”, “Tokyo Sales Office”, etc. are registered in advance as landmarks. It shall be. Also, in this example, as shown in FIG. 20A, there is a movement trajectory up to the present, and when trying to get on the expressway from the Kyoto Interchange, the movement history using the expressway was previously searched. is there. Furthermore, when the user selects the detailed information shown in FIG. 20B, it is possible to know how long it took when using the movement history, and this helps to select the current driving route.

  In the present embodiment, the history search unit 105 searches for a movement history related to the current position. However, the driver may specify a destination or a landmark and search for a movement history that passes through the vicinity. It can be realized by the same method as described above. As a result, for example, it is possible to easily search a travel history when a trip has been made before, and it is possible to refer to the current travel plan by knowing the required time and the waypoint at that time. .

  Further, in the present embodiment, the movement history is searched by the search by point, but as shown in FIG. 21, it can be expressed in a calendar format using the time information of the movement history. In FIG. 21A, there is an underline on the day on which the movement history is accumulated, and the movement history can be displayed as shown in FIG. 21B by selecting the day by the user.

  Further, in the present embodiment, an example of searching using the movement history has been described, but by accumulating the movement history for each driver, the destination is accurately predicted using the movement history, It is possible to notify the user of the required time (see FIG. 22).

  In addition, when the movement history is accumulated, the movement may be different from the normal movement due to construction or traffic jam information. In such a case, a route different from usual is used only when construction is being performed. Therefore, a method for accumulating information that suddenly changes the route when the information such as the construction can be acquired in the usual route, that is, another accumulation method by the movement history temporary accumulation unit 101 is shown in FIG. It demonstrates using the flowchart of these. As the history accumulated in advance, as shown in FIG. 24, it is assumed that the vehicle passes through R0015 from the starting point, enters R0021 from the intersection of C1507, and arrives at the terminal point. At this time, the movement history is accumulated as shown in FIG.

  For such a history, as shown in FIG. 26, the user knows in advance that the C1507 is not able to pass through the construction by using information such as the network and VICS, and ends up through a route different from the normal route in FIG. A description will be given of a method of determining that the same route as the previous route is used when heading for a point and accumulating the history. In this example, unlike the flowchart of FIG. 10, until the engine is started and then stopped, it is not accumulated as a movement history, and when the engine is stopped, a new history is obtained by comparing with the usual history. It is determined whether or not to add as a history.

  First, the point where the engine is started and the intersection that has passed are stored in the memory as the current history (step 4101). Until the engine is stopped, the series of intersections that have passed are stored in the memory as the current history (step 4102).

  Then, comparison is made with the starting point and the ending point of the past movement history data (FIG. 25), and both the current history and the history within a certain range are selected at both points (step 4103). If it does not exist, it is accumulated as new history data as the movement history of FIG. Here, the first history data in FIG. 25 is selected as history data whose departure point and end point are close.

  Subsequently, the history data selected in step 4103 is set as a similar past history (step 4104). Then, it is determined whether or not there is information such as an accident or construction on the similar past history data (step 4105). If there is no information such as an accident or construction, the process proceeds to step 4108, where it is registered as new history data, and the algorithm is terminated. In other cases, that is, when there is an accident, construction, or the like, the process proceeds to step 4106.

  Then, it is determined whether or not there are three or more common intersections between the current history data and the similar past history selected in step 4104 (step 4106). If there is no common intersection, the process proceeds to step 4108, where it is registered as new history data, and the algorithm is terminated. In other cases, that is, when there are three or more common intersections, it is determined that the traveling direction has been changed due to an accident, construction, or the like, and the process proceeds to step 4107.

  In this travel, it is determined that the route has been changed due to construction, an accident, etc., and similar past history data that is a history that would have been traveled when there was no construction, an accident, etc. is newly registered (step 4107). ).

According to the above flow, it is possible to register a route as a history that would have been traveled when there was no construction, accident, etc., in response to a sudden change in route due to construction, an accident, or the like.
(Embodiment 2)
In the first embodiment, in order to register the movement history for each driver, the method of identifying the driver by comparing the past movement history of the driver with the movement history up to the current point has been described. . In the present embodiment, a method for identifying a driver using not only the driver's movement history but also the history of the driver's operation of the in-vehicle device will be described. This makes it possible to register the movement history for each driver, and to search the movement history for each driver.

  FIG. 27 is a functional block diagram showing an overall configuration of the movement history storage device 2000 according to the second embodiment of the present invention. The movement history storage device 2000 is a device that accumulates a movement history based on a driver's movement history and operation history. The device-specific device operation history storage unit 2001, the in-vehicle device operation temporary storage unit 2002, and the driver determination. A movement history storage unit 2004, a movement history temporary storage unit 2005, a movement history transfer unit 2006, and a movement history search unit 2007.

  The driver-specific device operation history accumulation unit 2001 is a storage unit such as a hard disk for accumulating operation history of in-vehicle devices for each driver. The in-vehicle device operation temporary storage unit 2002 is a processing unit including a memory or the like that stores a history of operation of the in-vehicle device by the current driver. The driver determination unit 2003 is a processing unit that compares the history information of the device operation history storage unit for each driver 2001 with the operation information of the in-vehicle device operation temporary storage unit 2002 and identifies the driver. The movement history accumulation unit 2004 for each driver is a storage unit such as a hard disk for accumulating the movement history for each driver. The movement history temporary storage unit 2005 is a processing unit including a memory or the like that temporarily stores the movement history of the vehicle. The movement history transfer unit 2006 is a driver obtained by the driver history comparison unit and the movement history accumulated in the movement history temporary accumulation unit 2005 based on the discrimination result of the driver discrimination unit 2003. It is a processing unit that transfers to the storage unit 2004. The movement history search unit 2007 is a processing unit that searches the movement history accumulated in the driver-specific movement history accumulation unit 2004.

  FIG. 28 is a diagram illustrating a hardware configuration of a car navigation system including the movement history storage device 2000. In FIG. 28, a display 2101 is an LCD or the like that displays a car navigation screen. The GPS sensor 2102 is a GPS sensor for acquiring the current position. The car navigation main body 2103 is a car navigation device in which map data such as a hard disk and a DVD is stored. The in-vehicle stereo 2104 is a stereo device for viewing music and radio in the car. The in-vehicle music server 2105 is a storage unit that stores music data to be reproduced by the in-vehicle stereo. The antenna 2106 is an antenna for receiving radio with a vehicle-mounted stereo.

  The operation of the car navigation system configured as described above will be described with reference to the flowchart of FIG.

  Now, the music playback history for each user is stored in the driver-specific device operation history storage unit 2001 as shown in FIG. In FIG. 30, for example, the user A indicates that “love song” has been reproduced to the end on July 21. Therefore, as shown in FIG. 31, a point correspondence table is set in advance for the operation of the in-vehicle AV device for each user, and points are calculated for each piece of music data (step 2201). In FIG. 31, when the music is played to the end, it is 1 point, and when the music is not liked and fast-forwarded, it is -1. In addition, regarding the music reproduced by the user until the search, it is determined that the user likes the music and is given 2 points.

  The driver discriminating unit 2003 calculates the number of points for each user's music using the point table of FIG. 31, and creates the table of FIG.

  Suppose that “love song” is played. The in-vehicle device operation temporary storage unit 2002 records that there is a device operation (step 2202), and the process proceeds to step 2203.

  Since the “love song” is reproduced from the table of FIG. 32, the number of points for the users A, B, and C becomes 12, −1, and 3, respectively, by the calculation of the driver discrimination unit 2003 (step 2203). . Then, the process proceeds to Step 2204.

  The threshold of the total number of points is set in advance in the case of 15 in this example. Therefore, since 12 is the highest in the current number of points (step 2204), the driver determination unit 2003 cannot determine the user and returns to step 2202.

  Next, suppose that the “blue sea” has been regenerated. Since the device has been operated (step 2202), the process proceeds to step 2203.

  From the table of FIG. 32, since the “blue sea” has been reproduced, the points for the users A, B, and C are 5, 4, and 1, respectively (step 2203), and the process proceeds to step 2204.

  The total number of points is 17 (12 + 5), 3 (-1 + 4), and 4 (3 + 1) for each user. Therefore, since the threshold value 15 for the total number of points set in advance has been exceeded (step 2204), the driver determination unit 2003 determines that the driver is the user A, and proceeds to step 2205.

  The movement history transfer unit 2006 registers the movement history up to the present time accumulated in the movement history temporary accumulation unit 2005 as the movement history of the user A in the movement history accumulation unit 2004 for each driver (step 2205). Note that steps 2206 to 2208 are the same as steps 705 to 707 in Embodiment 1, and thus description thereof is omitted here.

  According to the above flow, the user (driver) can be specified in consideration of the device operation history, and the movement history can be automatically registered for each user, and the same effect as in the first embodiment can be obtained. .

  In the present embodiment, the method for discriminating the driver using the music viewing history has been described. Furthermore, in recent years, it has become possible to easily record CD music data on a hard disk using an in-vehicle hard disk or the like. Therefore, when recording on the hard disk, it is possible to leave who recorded on the hard disk by registering as a user. In general, it is considered that the user often registers his / her favorite song in the hard disk, and the driver often plays the song. Therefore, it is possible to discriminate the driver by comparing the music being played in the car with information on who has registered in the hard disk.

  In the present embodiment, the driver is determined using the music viewing history, but a channel selection history such as FM broadcasting may be used. It may be used which of the FM broadcast and the AM broadcast is mainly listened to or which media such as tape, CD, MD, and DVD is mainly viewed.

  In this embodiment, the music viewing history is used. However, by using the movement history, time zone, day of the week, etc. used in the first embodiment together, the determination accuracy of the driver can be improved. .

  In this embodiment, the music viewing history is used. However, the moving image content viewing history may be used.

  In this embodiment, the music viewing history is used, but a speaker identification function based on voice recognition may be used.

  In this embodiment, the music viewing history is used. However, the driver may be determined using sensors attached to the vehicle such as the driver's seat position and the position of the rearview mirror.

  Moreover, in this Embodiment, although the driver was specified by the operation history for every music, you may specify a driver based on the music selection history and operation history for every music genre or every singer.

In addition, when registering music data in an in-vehicle server such as a hard disk that realizes a large storage capacity, as shown in FIG. 33, content registration history storage means for storing information of the user who registered the content is provided and stored. It is also possible to determine the driver using the information of the registrant of the content. Furthermore, although the present embodiment has been described with music content, general content such as video content such as moving images may be used.
(Embodiment 3)
In the first embodiment and the second embodiment, the driver is determined as one of the drivers registered in advance using the movement history or the device operation history. However, in the case of vehicle theft, cases other than those registered in advance may be considered. Therefore, if the driver is not registered in advance, it can be determined that the vehicle has been stolen and the vehicle owner can be notified.

  FIG. 34 is a functional block diagram showing the overall configuration of the movement history storage device 2600 according to Embodiment 3 of the present invention. This movement history storage device 2600 is a device capable of notifying the driver of the possibility of theft of the vehicle based on the movement history. The movement history storage unit 2601 for each driver, A temporary storage unit 2602, a driver-specific history comparison unit 2603, an owner position detection unit 2604, and an owner communication unit 2605 are included.

  The movement history accumulating unit 2601 for each driver is a storage unit such as a hard disk for accumulating the movement history for each driver. The movement history temporary storage unit 2602 is a processing unit including a memory or the like that temporarily stores the movement history of the vehicle. A driver-specific history comparison unit 2603 is a processing unit that compares the movement history accumulated in the movement history temporary accumulation unit 2602 with the movement history accumulated in the driver-specific movement history accumulation unit 2601 to determine the driver. is there. The owner position detection unit 2604 is a processing unit that detects the position of the owner of the vehicle. The owner communication unit 2605 is a processing unit that contacts the owner when the driver is an unknown driver and inconsistency occurs in the position detected by the owner position detection unit 2604.

  FIG. 35 is a diagram illustrating a hardware configuration of a car navigation system including the movement history storage device 2600. In FIG. 35, a display 2701 is an LCD or the like that displays a car navigation screen. The GPS sensor 2702 is a GPS sensor for acquiring the current position. The car navigation main body 2703 is a car navigation apparatus in which map data such as a hard disk and a DVD is stored. The mobile phone communication unit 2704 is a communication processing unit that connects an external network connection device such as a mobile phone and car navigation. A cellular phone 2705 is a cellular phone.

  The operation of the car navigation system configured as described above will be described with reference to FIG. First, as shown in FIG. 11, each intersection information is accumulated as an intersection series of the user's movement history.

  Similarly to the first embodiment, it is determined whether or not the vehicle has passed the intersection (step 2801). If the vehicle has passed the intersection, the process proceeds to step 2802.

  Here, the driver-by-driver history comparison unit 2603 determines whether or not there is an intersection routed in step 2801 with respect to the intersection data accumulated as shown in FIG. 11 (step 2802). If it is at the intersection of FIG. 11, it is determined that the vehicle is traveling on the usual road, and the process returns to step 2801. If it is not at the intersection of FIG. 11, it is determined that the vehicle is not traveling on the usual road, and the process proceeds to step 2803.

  The driver-specific history comparison unit 2603 increments the history mismatch degree and proceeds to the next step (step 2803).

  If the history mismatch degree exceeds a predetermined threshold (for example, 3) (step 2804), it is determined that the driver may be a suspicious person without traveling on the usual road, and the process proceeds to step 2805. .

  Here, since there is a possibility that the driver is traveling on the road for the first time, the owner position detection unit 2604 uses the location information service of the mobile phone to determine where the vehicle owner is. The position is detected (step 2805). Further, a short-range wireless technology such as Bluetooth (registered trademark) is used to search for a Bluetooth-equipped mobile phone owned by the driver in the vehicle.

  When it is determined that the owner of the vehicle is in the vehicle or that the position of the vehicle and the position of the owner of the vehicle are close (step 2806), the owner communication unit 2605 determines that the driver is the owner of the vehicle and a new road Judge that you are driving and do nothing. If it is determined that the owner of the vehicle is away from the vehicle, the owner communication unit 2605 proceeds to step 2807, assuming that the vehicle may have been stolen.

  The owner contact unit 2605 automatically contacts the mail address of the vehicle owner to the mail “there is a possibility of theft” or the mobile phone number registered in advance (step 2807).

  As mentioned above, when the vehicle is heading to a new location using the past movement history of the vehicle, after confirming the position information of the owner of the vehicle, a notification that there is a possibility of theft is given. Do. As a result, the owner or the like who has been contacted can know theft of the vehicle.

  In this embodiment, the owner contact unit 2605 sends a predetermined e-mail to the e-mail address of the vehicle owner or automatically sends it to a mobile phone number registered in advance. The dealer is not limited to the vehicle owner, or may be a vehicle dealer (sales company), a security company, or the like in addition to the vehicle owner.

  Further, the coping method can be changed according to the degree of coincidence with the past movement history. Conventionally, as disclosed in Japanese Patent Application Laid-Open No. 2001-343446, a point where a vehicle is scheduled to travel is registered with a vehicle operation management sheet or the like, and the vehicle owner is notified when traveling in a location different from the registered content. Technology is disclosed. However, it is necessary to register the moving range of the vehicle in advance. In order to travel in a new place, a management sheet indicating the movement range of the vehicle must be registered again.

In contrast to this technique, in the present invention, the user does not need to register the range in which the vehicle travels in advance, and the user's travel range can be automatically determined using the past travel history. In a commercial vehicle, it is common to register a vehicle operation management sheet or the like, but in a general user's vehicle, registering it individually is troublesome. In addition, in order to determine whether the vehicle has been stolen using past movement history information, it is not determined that the vehicle is stolen even if it is slightly off the route in an area where there is a lot of movement history. However, when traveling on a different route, it is possible to determine that the theft has occurred. It is also possible to determine that the vehicle has been stolen if the vehicle is in a certain distance from the place where the vehicle is parked for a long time at night, and the user's life sphere is used for a long time. become.
(Embodiment 4)
In the first embodiment and the second embodiment, the method for automatically accumulating the movement history for each driver is described. Further, even in the case of the same driver, if the movement history is stored in a hard disk or the like, there is a possibility that it may be viewed by another person. Further, in a business vehicle, there is a case where a gasoline fee is paid according to the distance moved, or a treatment is paid according to the distance. In this case, private movement must not be stored as a movement history.

  Therefore, in the present embodiment, a method will be described in which the movement history is not automatically registered if the driver sets areas, places, landmarks, landmark types, etc. in which the history is not accumulated in advance.

  FIG. 37 is a functional block diagram showing the overall configuration of the movement history storage device 2900 according to the fourth embodiment of the present invention. This movement history storage device 2900 is an apparatus that can be set so as not to store a movement history that satisfies a certain condition. A movement history storage unit 2901, a movement history temporary storage unit 2902, a history storage rejection setting Section 2903, history storage section 2904, and history search section 2905.

  The movement history accumulation unit 2901 is a storage unit such as a hard disk for accumulating movement history. The movement history temporary accumulation unit 2902 is a processing unit including a memory or the like that temporarily accumulates a vehicle movement history. The history accumulation refusal setting unit 2903 is a processing unit that sets a case where no history is accumulated. The history accumulation unit 2904 determines whether or not to accumulate the movement history accumulated in the movement history temporary accumulation unit 2902 based on the content set in the history accumulation rejection setting unit 2903. The processing unit moves the history of the temporary storage unit 2902 to the movement history storage unit 2901. The history search unit 2905 is a processing unit that searches for a movement history.

  The hardware configuration of the car navigation system provided with this movement history storage device 2900 is the same as the configuration shown in FIG.

  The operation of the car navigation system configured as described above will be described with reference to FIG.

  First, the history accumulation refusal setting unit 2903 sets a region for deleting a history through dialogue with the driver (step 3001). For example, as shown in FIG. 39, since the movement history near “home” becomes large and is likely to be unnecessary when searching, the user should set the area around “home” as the movement history deletion area. Can do.

  As described in the first embodiment, the movement history temporary storage unit 2902 determines whether or not the vehicle has passed the intersection (step 3002). If so, proceed to the next step.

  Each time the vehicle passes through the intersection, the movement history temporary storage unit 2902 registers it in the internal memory (step 3003).

  It is determined whether or not the vehicle has stopped (step 3004). If the vehicle has not stopped, the process returns to step 3002. If stopped, proceed to the next step.

  The history accumulation unit 2904 determines whether or not the position information of the departure place and the stop position is within a predetermined distance (within 1 km) set in advance from the point set in Step 3001 (Step 3005). As a result, if it is within a certain distance, it is determined as a movement history to be deleted, and the process proceeds to Step 3006. If the distance is not within the predetermined distance, the process proceeds to step 3007, where the history accumulation unit 2904 moves the contents accumulated in the movement history temporary accumulation unit 2902 to the movement history accumulation unit.

  When it is determined that the position information of the departure place and the stop position is within a predetermined distance from the point set in step 3001, the movement history stored in the movement history temporary storage unit 2902 is displayed. Delete and do not register in the movement history storage unit 2901 (step 3006).

  With the above processing, the movement history related to the region that the driver does not want to accumulate is not accumulated.

  In the present embodiment, in step 3001, an area in which no movement history is accumulated is set with position information such as “home”. Furthermore, it is also possible to set by landmark type such as “hotel”, “convenience store”, “gas station”, etc., using landmark information on the map as shown in FIG. Thereby, for example, it becomes possible not to register the movement history of stopping or leaving at the “gas station”. In addition, when it is not desired to accumulate the movement history around a specific facility, the movement history may not be accumulated when the vehicle departs or stops within 10 meters from the location of the facility. It becomes possible.

  Further, in the present embodiment, movement history information relating to the surroundings of a point set by the user is not automatically accumulated. Therefore, it is also possible to notify the driver when the number of routes that should be accumulated originally exceeds a preset threshold value. As a result, if a driver other than the original driver did not know that the driver had set the movement history deletion function, he / she deleted the driver after driving to some extent. It becomes possible to confirm that the function is set.

In this embodiment, the movement history satisfying a certain condition is not accumulated in the movement history accumulating unit 2901. However, once accumulated in the movement history accumulating unit 2901, the movement history or the movement history satisfying the certain condition is stored. The route may be deleted. At that time, confirmation of deletion may be requested from the user via the screen, or the movement history directly designated by the user may be deleted or edited. As a result, when it is desired to delete a part of the movement history after being stored in the movement history storage unit 2901, the movement history can be edited in accordance with the user's circumstances.
(Embodiment 5)
In the fourth embodiment, the function of deleting the movement history data in the area designated by the user is described. However, when the movement history is deleted, the end point of the previous movement history is different from the starting point of the subsequent movement history, and it becomes clear that the movement history is deleted, and privacy is not protected. Therefore, in this embodiment, there is provided an apparatus for changing a movement history so that not only an unnecessary history is deleted but also a history context can be maintained.

  FIG. 41 shows the configuration of the movement history storage device in the present embodiment. This movement history storage device is an apparatus capable of automatically correcting a history so as to maintain time continuity when a part of the movement history is deleted, and includes a movement history storage unit 4001, a history deletion request input unit 4002, a deletion movement history selection unit 4003, a deletion section detection unit 4004, and a time information change unit 4005.

  The movement history accumulation unit 4001 is a hard disk or the like that accumulates movement history. The history deletion request input unit 4002 is a GUI or the like for a user to input a point / area to be deleted. The deletion movement history selection unit 4003 is a processing unit that selects a movement history to be deleted from the movement history accumulated in the movement history accumulation unit 4001 based on the request input by the history deletion request input unit 4002. The deletion section detection unit 4004 is a processing unit that selects a section to be deleted with respect to the movement history selected by the deletion movement history selection unit 4003. The time information change unit 4005 is a time information change unit that changes the passage time information of the movement history based on the section detected by the deletion section detection unit and stores it in the movement history storage unit 4001.

  The operation of each block will be described. In the movement history storage unit 4001, as shown in FIG. 42 (FIG. 42 (b) shows an example of stored data, FIG. 42 (a) shows an example of the data displayed on a map) The position information by the acquired latitude and longitude is accumulated. In the history deletion request input unit 4002, as shown in FIG. 43, position information for accumulating the movement history is input by the user. FIG. 43 shows an example in which history information via a rental video store is input to be deleted. Here, the location on the map is designated, but an area to be deleted may be designated in the vicinity of the home. In addition, the time for deleting the history may be designated, for example, it may be set to delete the holiday travel history. In addition, a request for deleting the history may be specified by the category information of the waypoints. For example, it may be specified that history information that has passed through a gas station is deleted, or history information that is visited at a play facility is deleted.

  The deletion movement history selection unit 4003 selects a movement history including the position information input by the history deletion request input unit 4002 from the movement history accumulated in the movement history accumulation unit 4001. When the request input by the history deletion request input unit 4002 is position information, the movement history information whose distance to the position information is within 10M is selected from the movement history stored in the movement history storage unit 4001. As a result, for example, as shown in FIG. 42, the travel history is selected from the company via the intersection A to the rental video store, returning to the intersection A, and going home. As the movement history, information on each position information and the time passing through the position is accumulated.

  The deletion section detection unit 4004 determines a section for deleting the movement history by selecting position information to be deleted with respect to the movement history selected by the deletion movement history selection unit 4003. Specifically, with respect to the movement history instructed to delete, for the position information for which the deletion instruction has been received, the history through the same intersection is searched before and after the position information. That is, in the example of FIG. 42, it can be seen that the vehicle passes through the intersection A before and after visiting the rental video store. Therefore, in order to delete the movement history of visiting the rental video store, the history of moving the rental video store from the intersection A and the history of moving from the rental video store to the intersection A are set as history deletion sections. As a result, a shift occurs in the time when the user was at the intersection A. Therefore, the time information change unit 4005 changes the time information of the movement history.

  The time information change unit 4005 is a processing unit for avoiding that the deletion section detection unit 4004 deletes a history of a predetermined section, so that there is no section in which no user movement history exists. The time information of the history including the movement history of the section to be changed is changed. Here, the time taken from the departure point to the arrival at the intersection A is compared with the time taken from the intersection A to the end point, and the movement history for a short time is changed. In the example of FIG. 42, since the time taken to move from the departure place to the intersection A is shorter, FIG. 44 (FIG. 44 (b) shows an example of data after change, and FIG. 44 (a) shows the data. As shown in the example shown on the map, a natural movement history is generated by delaying the time of departure from the departure place (company). As a result, as shown in FIG. 44, the departure time of the company is 19:12, and the same movement history as the time before the change can be generated at the time of arrival at the home. The changed movement history is accumulated in the movement history accumulation unit 4001. If the departure time is desired to be the same, the time information of the movement history from the intersection A to the home that is the final destination is changed. As a result, it is possible to generate a movement history as shown in FIG. 45 (FIG. 45 (b) is an example of data after change, and FIG. 45 (a) is an example of displaying the data on a map).

  The above operation is summarized in the flowchart of FIG. When there is a deletion request in the history deletion request input unit 4002, the process proceeds to the next step (step 4101). If there is no deletion request, this step is repeated to wait for the deletion request to be input. When position information is input in step 4101, the deletion movement history selection unit 4003 obtains movement history data including position information at a distance of 10 M from the input point from the history accumulated in the movement history accumulation unit 4001. Search is performed (step 4102). The deletion section detection unit 4004 checks whether or not there is a common intersection before and after the point to be deleted specified in Step 4101 in the movement history searched in Step 4102 (Step 4103). In the example of FIG. 42, the intersection A is extracted as a common intersection. If there is a common intersection, the process proceeds to step 4105. If there is no common intersection, the process proceeds to step 4110. In the example of FIG. 42, since the intersection A exists as a common intersection, the rental video store from the intersection A and the round-trip section of the intersection A from the rental video store are selected as the sections to be deleted (step 4104). The section to be deleted is selected as three pieces of position information from 19:12 to 19:15, and the travel time in that section is calculated as 3 minutes (step 4105). The time information change unit 4005 is from the departure point (company) to the common intersection A (19:09 to 19:12) and from the common intersection to the end point (home) (19:15 to 19:29) Is calculated (step 4106). If it is closer to the departure place, the process proceeds to step 4108, and if it is far, the process proceeds to step 4109 (step 4107). In the case of FIG. 46, since the distance from the departure place is shorter, the time information of the movement history from the departure place to the common intersection A is changed as shown in FIG. 44 (step 4108). When the time until the final destination is shorter, the time information is changed as shown in FIG.

  In step 4103, if there is no common intersection, the process goes to step 4110 to delete the movement history from the departure point to the final destination. For example, in the movement history example shown in FIG. 47 (FIG. 47 (b) is an example of data, and FIG. 47 (a) is an example of displaying the data on a map), it goes from the company to the home via the rental video store. If there is, there is no common intersection. Therefore, a method for changing the movement history by selecting a common road instead of the common intersection in the flowchart of FIG. 46 will be described. In FIG. 47, the route from the company to the home departs from the company, travels R101, turns around the intersection A, stops at the rental video store via R102, then travels again through R102, and then passes through R103 and R104. And it will be a history of arrival at home. It is assumed that each road is registered in advance as road ID information. Here, in order to delete the information that has come to the rental video store, the history of traveling on the common road is searched before and after the history of the rental video store, and the common road is defined as the common intersection of the embodiment. It is possible to change the time information of the movement history by regarding it. As a result, R102 is selected as the common road, and as a result, the movement history shown in FIG. 48 (FIG. 48 (b) is an example of data after change, and FIG. 48 (a) is an example of the data displayed on a map). Be changed.

In the present embodiment, the deletion movement history selection unit 4003 selects one piece of movement history data including the point information input by the history deletion request input unit 4002. However, a plurality of movement histories may be selected. For example, as shown in the movement history example shown in FIG. 49 (FIGS. 49B and 49C are examples of different movement history data, and FIG. 49A is an example in which those data are represented on a map) When the engine of the vehicle is stopped at the video store, the history data visiting the rental video store is composed of a plurality of movement histories. Therefore, history data whose position information matches and shorter than a preset time (for example, 1 hour) is determined to be continuous travel history data, and the history of moving from the company to the rental video store and the rental By treating the history of moving from the video store to the home as a continuous history, it is possible to delete and edit the movement history with the same mechanism as in the present embodiment.
(Embodiment 6)
In the fifth embodiment, a method has been described in which the history information that has been instructed to be deleted by the user is deleted and the time information of the history is corrected by changing the time information of the selected movement history. However, if the time information is changed, the departure time and arrival time may not be consistent with the actual travel history. Therefore, in the present embodiment, a method for updating the movement history without changing the departure time and arrival time by changing the position information will be described.

  FIG. 50 shows the configuration of the movement history storage device of the present embodiment. This movement history storage device is an apparatus capable of automatically correcting the history of a halfway point while maintaining the departure time and arrival time even when a part of the movement history is deleted. , A history deletion request input unit 4902, a deletion movement history selection unit 4903, a deletion section detection unit 4904, and a position information change unit 4905. Since this configuration corresponds to the configuration in Embodiment 5 in which the time information change unit 4005 is changed to the position information change unit 4905, description of common parts (components having the same names) is omitted.

  In the position information change unit 4905, the accumulated position information is changed so that the section detected by the deletion section detection unit 4904 does not become an unnatural history. Note that this unnatural history is different from the final point in the movement history and the starting point of the next history, or in the movement history that is accumulated as a history of moving only a specific section at high speed. It is a movement history that rarely occurs.

  In this example, the rental video from the company as shown in the movement history example shown in FIG. 51 (FIG. 51 (b) is an example of accumulated data, and FIG. 51 (a) is an example of the data displayed on a map). A case will be described in which the history of visiting the rental video store is deleted from the history of moving to the home via the store. In FIG. 51, it can be seen that the rental video store went through from 19:13 to 19:18 for 5 minutes. Therefore, a virtual history is generated by changing the position information of the movement history that has already been accumulated for the five-minute history. If the five-minute movement history is simply deleted, the movement history from 19:13 to 19:18 does not exist and is accumulated as an unnatural history. Therefore, from 19:13 to 19:18, certain position information is accumulated and changed and corrected as an unnatural movement history from the context.

  Regarding the calculation method of the section to be deleted, the same processing as in the fifth embodiment is performed using history information passing through a common intersection and history information traveling on a common road before and after the history to be deleted in the movement history. To decide. In the example of FIG. 51, as in the case of FIG. 47 of the fifth embodiment, the vehicle travels R102 before and after the movement history to be deleted. Therefore, the movement history to be deleted is determined before and after leaving from R102.

  First, the required time from the departure point to the end point is calculated in the movement history. In the example of FIG. 51, since it departed at 19:09 and arrived at 19:24, it takes 15 minutes. Next, since the stop time is 5 minutes from 19:13 to 19:18, the travel time is 10 minutes minus the time. Next, the distance to the next moving point at each point is obtained. The result is shown in FIG. In FIG. 52 (a), the distance to the next moving point at 19:09 is 32M. Next, 10 (net travel time) / 15 (travel time) is calculated, and the distance is reduced by the calculated ratio with respect to the travel distance at each point. The result is shown in “corrected travel distance” in FIG. Using this corrected distance, a moving point from the departure point and a moving point from the final destination are obtained.

  Since the position set to a distance smaller than the actual travel distance is obtained, the movement history around the point to be deleted disappears as shown in FIG. Therefore, positions between 19:13 and 19:18 are allocated at equal intervals to the section having no movement history. The result is shown in FIG. In FIG. 52 (b), the calculation result is 12M. When this is expressed on a map, position information is calculated as shown in FIG. As a result of the above, it is possible to generate a movement history in which the departure point and the arrival point are the same, and the departure time and arrival time are the same, and can be registered in the movement history storage unit.

  The above operations are summarized in the flowchart of FIG. In FIG. 54, steps 5001 to 5004 and step 5011 are the same as those in the fifth embodiment, and thus the description thereof is omitted. As a result of the operation up to step 5004, the section for deleting the movement history is determined, and the process proceeds to step 5005. Next, the position information changing unit 4905 calculates the required time from the departure point to the final destination (step 5005), resulting in 15 minutes. Next, the required time excluding the time during which the vehicle was stopped is calculated, resulting in 10 minutes (step 5006). Next, the position information changing unit 4905 calculates the movement distance (speed) per unit time at each point, and generates the table of FIG. 52A (step 5007). The product of 10/15 = 0.667 with respect to the calculated moving distance is calculated, and the moving distance at each point is shortened (step 5008). The position information on the map is calculated using the calculated moving distance (step 5009). The position information is calculated from the departure point for the time before the deletion section, and calculated from the end point for the time after the deletion section, so that a blank section occurs in the deletion section. Therefore, the position information changing unit 4905 generates a new movement history by equally dividing the blank section. As a result of the above operation, a movement history excluding the deletion section requested by the user can be generated and stored in the movement history storage unit.

In this embodiment, new position information is determined using the movement distance (speed) at each point, and then the position information of the deleted movement history is determined. Conversely, after determining the position information of the deleted movement history, the other movement history may be corrected. Specifically, the position information of the movement history from 19:14 to 19:19 is first determined using the average speed set in advance around the rental video store, and then the average speed at each point is determined. Use this to change the position information at each time. FIG. 55 shows the relationship between time and moving distance. As shown in FIG. 55 (FIG. 55 (a) shows the relationship between the time and the moving distance before the correction, and FIG. 55 (b) shows the relationship between the time and the moving distance after the correction) In the movement history section), a movement history is created assuming that the user has moved at a constant speed. Thereafter, the travel distance from the starting point and the final destination for the section traveling at a constant speed is reduced by the same ratio as the actual traveling.
(Embodiment 7)
In the sixth embodiment, it is possible to create the same movement history with the same departure place and arrival place, and the same departure time and arrival time. However, when the time of the movement history to be deleted becomes longer, a history of traveling at a slower speed than usual is generated, and an unnatural movement history may be generated. Therefore, in the present embodiment, a method for generating a fictitious movement history by referring to a past movement history and generating a new movement history based on the history will be described.

  FIG. 56 shows the configuration of the movement history storage device in the present embodiment. This movement history storage device generates a fictitious movement history when a part of the movement history is deleted, thereby making the departure place and the arrival place the same, and further providing a natural movement history with the same departure time and arrival time. It is a device that can be created, and includes a movement history accumulation unit 5401, a history deletion request input unit 5402, a deletion movement history selection unit 5403, a deletion section detection unit 5404, a waypoint determination unit 5405, and a movement history generation unit 5406. This configuration is the same as in the fifth and sixth embodiments with respect to the parts (components having the same names) other than the waypoint determination unit 5405 and the movement history generation unit 5406 that determine a waypoint from the past movement history. Is omitted.

  The waypoint determination unit 5405 selects a travel history that replaces the deletion section from the movement history already accumulated in the movement history accumulation unit 5401 according to the deletion section detected by the deletion section detection unit 5404, and creates a new route. Determine the point. For example, it is assumed that the same movement history as that in FIG. 42 of the fifth embodiment is selected as the deletion movement history from the movement history accumulation section 5401 by the history deletion request input section 5402. At this time, it is assumed that the deletion history detection unit 5404 detects a movement history of going back and forth from the intersection A as a section to be deleted. At this time, in the fifth embodiment, a new movement history is generated by changing the time information of the movement history. On the other hand, in this embodiment, a movement history is generated by setting a new waypoint. As a new waypoint, a route history point that is at a distance similar to the rental video store with respect to the movement history that is set as the movement history to be deleted in the movement history accumulation unit 5401 is already a movement history accumulation unit 5401. Select from the movement history stored in. Here, as a travel history example shown in FIG. 57 (FIG. 57 (b) is an example of accumulated data, FIG. 57 (a) is an example in which the data is displayed on a map) “Super BIG” is selected, and the super BIG is determined as a waypoint.

  Further, the movement history generation unit 5406 deletes the round-trip route of the rental video store from the intersection A, and newly generates a movement history via “Super BIG”. The generated movement history is accumulated in the movement history accumulation unit 5401. Thereby, a new movement history is generated and can be replaced with a natural movement history.

  The above processing flow will be described with reference to the flowchart of FIG. Note that steps 5501 to 5505 and step 5508 in the flowchart of FIG. 58 are the same as those in the fifth embodiment, and thus the description thereof is omitted. The waypoint determination unit 5405 selects, from the landmarks accumulated in the movement history accumulation unit 5401, a landmark that spends a time close to the time during which the deletion segment detected by the deletion segment detection unit 5404 was traveling (step 5505). ). The movement history generation unit 5406 generates a movement history via the selected landmark, and accumulates it instead of the movement history to be deleted (step 5507).

  In this embodiment, a new movement history is generated using a landmark visited in the past (a landmark accumulated in the movement history accumulation unit 5401). Furthermore, it is possible to select a landmark that has been visited but not actually visited by using the time information of the movement history. Accordingly, it is possible to generate a movement history according to the user's life pattern, such as a restaurant at lunch time or a shopping center at home.

  By using the departure time, departure point, arrival time, and arrival point information of the movement history, a similar movement history is searched from the already accumulated movement history, so that the movement can be substituted for the movement history to be deleted. It is also possible to select a history. It is also possible to store the selected movement history instead of the deleted movement history.

  In the present embodiment, an alternative history is selected using the movement history of the driver who deletes the history. Furthermore, a substitute movement history may be selected using the movement history of another person. Since the movement history information made public by other people is generally history information that allows a third party to browse, it is often history information that has no problem even if it is used as deleted history information. Therefore, there are many cases where the privacy problem is eliminated by using the movement history information of general users published on the Internet or the like.

  In the present embodiment, since the accumulated history information is browsed by others, it may be used for the purpose of changing / deleting history information including privacy. Therefore, the movement history changing method may be changed using information on which users view the accumulated history information. For example, if the movement history is viewed only by the family, the history information that is substituted for the deleted movement history is generated and stored as a new movement history using the movement history that the family has moved in the past. Also good. This can be realized by setting a new waypoint with reference to the family movement history in the waypoint determination unit in the structure of the movement history storage device shown in FIG.

  The movement history accumulating apparatus and method of the present invention can be applied as an apparatus for automatically discriminating a driver and accumulating the movement history, particularly as a car navigation system or the like, even if the driver does not designate it. Furthermore, the present invention can be applied to a mobile terminal such as a mobile phone.
