(Embodiment)
FIG. 1 is a block diagram of a functional configuration of the drive plan creation apparatus according to the embodiment. The drive plan creation apparatus 100 according to the embodiment includes a movement history information acquisition unit 101, a specification unit 102, a presentation unit 103, a road traffic information acquisition unit 104, a creation unit 105, and an output unit 106. In addition, each component of the drive plan creation apparatus 100 may realize its function with a single piece of hardware, or may realize its function with a plurality of pieces of hardware.

  The movement history information acquisition unit 101 acquires movement history information of a moving object. The moving history information of the moving object includes, for example, stop-off feature information regarding the feature that the moving object has stopped while moving, stay time information regarding the time spent on the feature, and route information related to the route traveled by the moving object. It is. The travel history information includes the date of the recorded drive, weather conditions, passengers, situations (such as “date”, “family trip”, and “refresh”), the location of the start and end points of travel. Information etc. may be recorded. Hereinafter, each item (parameter) included in the travel history information is referred to as “history parameter”, and the value of the history parameter is referred to as “history parameter value”.

  The movement history information acquired by the movement history information acquisition unit 101 may be movement history information of a moving body that moves using a drive plan created by the creation unit 105 described later, or is created by the creation unit 105. It may be movement history information of a moving body different from the moving body that moves using the drive plan. When acquiring movement history information of a moving object different from the moving object that moves using the drive plan, the movement history information acquiring unit 101 receives the movement history information via a communication network, for example.

  In addition, the movement history information acquisition unit 101 uses the movement history information from a predetermined point (for example, a user's home) to a point where the moving object has been determined in advance as a unit. It is good also as acquiring. Further, the movement history information acquired by the movement history information acquisition unit 101 may be a history of movement along a drive plan created using the drive plan creation device 100 (or another drive plan creation device). A history of moving along a drive plan created by the user himself or a history of moving without specifying a plan may be used.

  The designation unit 102 accepts designation of conditions used for creating a drive plan. The conditions used for creating the drive plan include, for example, the date and time of driving, the starting point of driving, the stopping point during the driving, the required time, the necessity of eating, the attributes of the passengers, the purpose of driving, and the like. One or more items may be specified for the specified condition. The condition specified by the specification unit 102 is an element that defines parameters to be determined when creating a drive plan (for example, a drive destination point, a stop point, a staying time at the stop point, a required time, etc.). Hereinafter, a value obtained by adapting each parameter included in the drive plan to a condition is referred to as a “condition parameter value”. The condition parameter value is not necessarily uniquely determined from the specified condition, and may have a predetermined width or a plurality of values, for example. Moreover, the designation | designated part 102 is good also as accepting designation | designated of any movement history information among the movement history information presented by the presentation part 103 mentioned later.

  The presentation unit 103 presents the movement history information acquired by the movement history information acquisition unit 101 to the user. The travel history information may be presented, for example, by text information indicating the name of the stop point, the staying time at the point, the required time for moving the route, or the route of the drive plan on the map information May be displayed. For example, the presenting unit 103 presents the movement history information with the movement history information from a predetermined point to returning to the predetermined point as one unit.

  The road traffic information acquisition unit 104 acquires road traffic information when the drive plan is executed. The road traffic information acquisition unit 104 acquires real-time road traffic information such as VICS (registered trademark) information or information uploaded from a vehicle actually traveling on the road, for example, when the drive plan is executed. Get road traffic information. Further, the road traffic information acquisition unit 104 may acquire a statistical value of past road traffic information and predict a road situation at the time of executing the drive plan.

  The creation unit 105 uses the movement history information acquired by the movement history information acquisition unit 101 to create a drive plan that meets the conditions specified by the specification unit 102. For example, the creation unit 105 creates a drive plan by changing a history parameter value included in the movement history information to a condition parameter value.

  For example, the creation unit 105 selects, from a plurality of pieces of movement history information, movement history information including a history parameter value whose error rate with a condition parameter value is a predetermined value or less, and sets the history parameter value included in the movement history information as a condition Change to parameter values and create a drive plan. That is, the past movement history information similar to the designated condition is changed so as to match the designated condition this time, and a drive plan is created.

  More specifically, for example, when a predetermined feature that is a destination point of the drive plan to be created this time is designated as the condition parameter value, the creation unit 105 selects the designated feature or the same genre as the feature. The travel history information having the feature as the destination point is selected, and the history parameter values other than the destination point included in the movement history information are changed so as to match the condition parameter value, and the drive plan is created. At this time, a plurality of movement history information may be selected to create a plurality of drive plans.

  Further, when a plurality of conditions used for creating the drive plan are specified, the creating unit 105 assigns points to each of the history parameters (stopping point, departure point, passengers, etc.) included in the travel history information, for example, The error rate may be collated by accumulating points of items that match the value and the condition parameter value. In this case, the creation unit 105 creates a drive plan using, for example, movement history information having the highest accumulated points (or a predetermined value or more).

  Also, when the movement history information itself is designated by the designation unit 102, the creation unit 105 creates a drive plan by changing the history parameter value included in the designated movement history information to the condition parameter value. In this case, for example, the creation unit 105 adjusts the stop feature information, the staying time information, the route information, and the like included in the designated movement history information according to the current road conditions (when driving), and drives Create a plan. In other words, if the user wants to “drive with the same plan as this movement history information”, the movement history information may be designated directly from the designation unit 102.

  Further, for example, the creation unit 105 may statistically process the history parameter value included in the movement history information, and create a drive plan using the average value or the mode value of the history parameter value under the specified condition. Good. That is, instead of using only specific movement history information, a drive plan may be created by extracting user preferences from a plurality of movement history information. In this case, the creation unit 105 creates a drive plan using the average value for parameters whose average value can be calculated, such as a stop time at a stop point or a required time of a predetermined section on the road. In addition, for a parameter that cannot be calculated as an average value, such as a destination point of a drive plan, a stop point, and a road to be used, a drive plan is created using the mode value.

  The creation unit 105 may create a drive plan that meets the conditions using the road traffic information acquired by the road traffic information acquisition unit 104 together with the travel history information. As a result, it is possible to reduce an error between the required time in the drive plan and the actual time required for moving. Further, the creating unit 105 may create a plurality of drive plans that meet the specified conditions.

  The output unit 106 outputs information related to the drive plan created by the creation unit 105. Information related to the drive plan includes, for example, text information and voice information describing the contents of the drive plan (departure point, stop point, stay time at the stop point, route, etc.), map information marking the route of the drive plan, drive Control information for controlling a navigation device (not shown) so as to guide the route along the plan.

  The output unit 106 outputs information related to the drive plan to a display output device such as a monitor (not shown) or an audio output device such as a speaker. As a result, the user can confirm the contents of the drive plan created by the creation unit 105. Further, the output unit 106 may output information related to the drive plan to an information processing device (personal computer or navigation device) not shown, a portable recording medium (such as a USB memory or an SD card), and the like. As a result, information relating to the drive plan can be used even in an information processing apparatus that is not integrated with the drive plan creation apparatus 100. Further, the output unit 106 may transmit information on the drive plan to an information processing apparatus (not shown) via a network.

  Next, drive plan creation processing by the drive plan creation apparatus 100 will be described. FIG. 2 is a flowchart showing a procedure of drive plan creation processing by the drive plan creation device. In the flowchart of FIG. 2, the drive plan creation apparatus 100 first acquires the movement history information of the moving body by the movement history information acquisition unit 101 (step S201). Next, the drive plan creation apparatus 100 accepts designation of conditions used for creating a drive plan by the designation unit 102 (step S202). At this time, the movement history information may be presented to the presentation unit 103 to allow the user to select which movement history information is used to create the drive plan.

  Subsequently, the drive plan creation apparatus 100 creates a drive plan that meets the conditions specified in step S202 by using the creation unit 105 (step S203). Then, the drive plan creation apparatus 100 outputs information related to the drive plan by the output unit 106 (step S204), and ends the processing according to this flowchart.

  As described above, the drive plan creation apparatus 100 according to the embodiment creates a drive plan by adapting the movement history information of the moving object to the designated condition. As a result, the error between the parameter value in the drive plan (for example, the required time and stay time at the destination) and the actual value can be reduced, and the possibility that the drive plan can be executed as planned is increased. Can do.

  In addition, since the drive plan creation apparatus 100 according to the embodiment creates a drive plan by changing the history parameter value to the condition parameter value, the processing load when creating the drive plan can be reduced. In addition, if the travel history information is presented to the user and a drive plan is created using the travel history information selected by the user, it is possible to reduce the effort for the user to input the conditions.

  In addition, it is possible to create a drive plan reflecting the user's preference by statistically processing the movement history information and creating a drive plan using an average value of parameters under specified conditions. In addition, if the road traffic information at the time of executing the drive plan is used when creating the drive plan, the error between the required time in the drive plan and the actual required time can be reduced, and the drive plan is executed as planned. The possibility of being able to be increased can be increased.

  In addition, the drive plan creation apparatus 100 can create a drive plan using movement history information of a moving body that moves using a drive plan created by the own apparatus, so that the user's preference is reflected in the drive plan. Can do. In addition, the drive plan creation apparatus 100 can create a drive plan using movement history information of a moving body that is different from the moving body that moves using the drive plan created by the own apparatus. The width can be increased.

  Next, an example of the drive plan creation apparatus 100 according to the above-described embodiment will be described. In the following example, an example in which the drive plan creation device 100 according to the embodiment is applied to a drive plan creation function of a navigation device mounted on a vehicle will be described.

  The magnetic disk drive 304 controls the reading / writing of the data with respect to the magnetic disk 305 according to control of CPU301. The magnetic disk 305 records data written under the control of the magnetic disk drive 304. As the magnetic disk 305, for example, an HD (hard disk) or an FD (flexible disk) can be used.

  The optical disk drive 306 controls the reading / writing of the data with respect to the optical disk 307 according to control of CPU301. The optical disk 307 is a detachable recording medium from which data is read according to the control of the optical disk drive 306. As the optical disc 307, a writable recording medium can be used. In addition to the optical disk 307, the removable recording medium may be an MO, a memory card, or the like.

  Another example of information recorded on the magnetic disk 305 or the optical disk 307 is map data used for route search / route guidance. The map data includes background data representing features (features) such as buildings, rivers, and the ground surface, and road shape data representing the shape of the road. The map data can be displayed two-dimensionally or three-dimensionally on the display screen of the display 314. Drawn. When the navigation device 300 is guiding a route, the map data and the current location of the vehicle acquired by the GPS unit 316 described later are displayed in an overlapping manner.

  The audio I / F 308 is connected to a microphone 309 for audio input and a speaker 310 for audio output. The sound received by the microphone 309 is A / D converted in the sound I / F 308. In addition, sound is output from the speaker 310. Note that the sound input from the microphone 309 can be recorded on the magnetic disk 305 or the optical disk 307 as sound data.

  Examples of the input device 311 include a remote controller having a plurality of keys for inputting characters, numerical values, various instructions, a keyboard, a mouse, a touch panel, and the like. Further, the input device 311 can be connected to another information processing terminal such as a digital camera or a mobile phone terminal to input / output data.

  The video I / F 312 is connected to a camera 313 for video input and a display 314 for video output.

(Drive plan creation function of the navigation device 300)
Next, the drive plan creation function of the navigation device 300 will be described. The navigation device 300 is provided with a drive plan creation function for creating a drive plan in accordance with conditions input by the user. Usually, a drive plan is created by searching for a destination point or a stop point that meets a condition specified by the user, and planning a stay time, a route, or the like at the destination point or the stop point.

  Here, the navigation apparatus 300 according to the embodiment accumulates the travel history information of the vehicle on which the own apparatus is mounted and uses it for creating a drive plan. By using the travel history information for creating the drive plan, it is possible to create a drive plan that suits the user's preference, and to reduce the user's trouble at the time of creating the drive plan.

  FIG. 4 is an explanatory diagram showing an example of vehicle travel history information. The travel history information 400 includes a travel history ID 401, travel date and time information 402, day trip / accommodation information 403, a stop point ID 404 for identifying a stop point, stop point information 405, stop point genre information 406, stay time information 407, and required time information. 408, a destination point check box 409, travel locus information 410, and the like. Each item constituting the travel history information 400 is referred to as “history parameter”.

  The travel history ID 401 is an ID for identifying individual travel history information. The travel history information is basically stored as one unit from the start of the travel start point to the destination point or stop point until the return to the travel start point. That is, instead of recording the movement trajectory from when the vehicle engine starts to when it stops, for example, it departs from the parking lot at the home (starting point of travel), stops at the destination or stopover point, and then parks at the home parking lot History information until returning to is recorded as one traveling history information. Further, the travel history information does not simply record only the movement trajectory of the vehicle, but includes information such as a stay time at a destination point or a stop point as will be described later.

  For example, the navigation device 300 records history information from a predetermined point set in advance by the user until returning to the predetermined point as one traveling history information. The unit in which the travel history information is recorded may be arbitrarily set by the user, or may be automatically set by the navigation device 300. Examples of the point that can be the travel start point and the travel end point include a point where a vehicle is registered in the garage, such as a parking lot at home.

  The travel date information 402 is information indicating the date and time when the travel was performed. The travel date / time information 402 may include a travel start time and a travel end time in addition to the date on which the travel was performed. The day trip / accommodation information 403 is information indicating whether the traveling was a day trip or accompanied by an overnight trip. For example, whether it is a day trip or an overnight stay is determined by checking whether or not the vehicle has returned to the travel start point by a predetermined time (for example, midnight, for example) You may add a condition such as “More than a predetermined time across time”).

  A stop point ID 404 for identifying a stop point is an ID for identifying a stop point in one travel history information. In the illustrated example, IDs are allocated without distinguishing between the destination point and the stop point, and the destination point and the stop point are distinguished depending on whether or not a destination point check box 409 described later is checked. Here, the destination point is a point intended to be reached by traveling. Further, the stop point is a point where the vehicle stops while traveling (stops for a predetermined time or more). Note that the destination point and the stop point need not be distinguished, and the destination point and the stop point may be assigned different IDs and managed independently.

  The stop point information 405 is information indicating the name and position (latitude and longitude, etc.) of the stop point. The navigation device 300 stops at the set destination point or stop point when the user stops the engine at a point within a predetermined distance from the destination point when the user sets the destination point or stop point and travels. The position information of the point where the vehicle stopped is recorded. This is because the position of the destination point or the stop point (mostly the position of the representative point) and the stop position of the vehicle rarely coincide completely.

  In addition, the navigation device 300 is in the vicinity of the stop point when the vehicle stops at a point that is not set as a destination point or a stop point, for example, when a predetermined time or more has passed since the vehicle stopped the engine. Search for a feature and record it as a stopover point. The reason for waiting for a predetermined time or more after the engine is stopped is to prevent erroneous determination of idling stop or the like as stopping.

  The navigation device 300 records the position of the point where the vehicle actually stops along with the destination point or stop point, and when the user stops at that point next time, the navigation device 300 guides to the position where the vehicle stopped.

  The stop point genre information 406 is information indicating the stop point genre. The genre of the drop-in point is a categorization of the drop-off point according to the purpose of use, such as “convenience store”, “restaurant”, “amusement park”, and the like. Moreover, the genre of the stop-off point may be provided hierarchically, for example, as a large classification, a medium classification, and a small classification.

  The major classification is, for example, a classification of the stop points according to the purpose of use, such as “restaurants”, “retail shops”, and “transportation”. The medium classification is, for example, a classification of facilities of the large classification “restaurant” according to the type of food provided, such as “Japanese food”, “Chinese food”, “Italian food”, and “Family restaurant”. The sub-category is, for example, a medium-category "Japanese food" facility that is classified according to more detailed types of cuisine such as "sushi restaurant", "soba restaurant", and "canteen restaurant", or according to chain stores. .

  The stay time information 407 is the time spent at the stop point, for example, the time elapsed from when the engine of the vehicle is stopped around the stop point until the engine is started again.

  The required time information 408 is a required time until moving from the previous stop point to the stop point. For example, the required time information 408 with a stop point ID 404 of 3 records a required time for moving from a stop point with a stop point ID of 2 to a stop point with a stop point ID of 3. Regarding the required time information 408 with a stop point ID of 1, the required time from the travel start point to the stop point with a stop point ID of 1 is recorded. In the travel history information, regarding the required time information 408 of the last stop point ID, the required time from the stop point of the last stop point ID to the travel end point is recorded.

  In the destination point check box 409, a check is made at a stop point that is considered as a destination point of the travel. For example, the navigation device 300 checks the destination point check box 409 on the assumption that the point (feature) designated as the destination point during the route search is the destination point. Further, when traveling without specifying the destination point, the navigation device 300 presents the traveling history information to the user when the traveling ends, for example, and designates which of the stop points is the destination point to the user. You may let them. Further, the navigation device 300 may automatically determine the stop point where the stay has been the longest as the destination point.

  The travel locus information 410 continuously records positions on a route along which the vehicle has moved. The travel locus information 410 records, for example, latitude / longitude information indicating the current position of the vehicle at a predetermined time or a predetermined distance. In the travel locus information 410, for example, vehicle current position information calculated by output signals from the GPS unit 316 and various sensors 317, matching information to map information, and the like are recorded. In the travel locus information 410, for example, only a traveling direction at a feature point on the route such as a traveling direction at a right or left turn point may be recorded.

  Next, drive plan creation processing by the navigation device 300 will be described. As described above, the navigation device 300 creates a drive plan using the vehicle travel history information (see FIG. 4). As a method of creating a drive plan using travel history information, for example, (1) creating a drive plan based on travel history information similar to the conditions of the drive plan created this time specified by the user (navigation device) 300 selects travel history information used for creating a drive plan), (2) creates travel history information using the drive plan selected by the user, and (3) analyzes the user's drive preference from the travel history information (statistics). Process) and creating a drive plan based on the analysis result. Hereinafter, a method combining (1) and (3) and a method (2) will be described as an example of a drive plan creation process by the navigation device 300.

  FIG. 5 is a flowchart illustrating an example of drive plan creation processing by the navigation device. The flowchart of FIG. 5 is a flowchart about the method which combined said (1) and (3). The navigation apparatus 300 first waits until an instruction to create a drive plan is issued (step S501: No loop).

  When creation of a drive plan is instructed (step S501: Yes), the navigation apparatus 300 displays an input screen for conditions used for creating a drive plan on the display 314 (step S502). The navigation device 300 may, for example, drive date / time, day / night designation, travel start and end points, destination point, stop-by point during driving, required time, necessity of meal, passenger attributes, purpose of driving, etc. Display a screen for entering etc. Note that not all of the above conditions may be input by the user, or conditions other than the above may be input by the user.

  The navigation device 300 waits until a condition is input by the user (step S503: No). When the condition is input (step S503: Yes), traveling history information similar to the input condition (hereinafter, “ It is determined whether there is "similar travel history information" (step S504). “Similar to the input condition” indicates, for example, that the error rate between the value of each parameter included in the travel history information and the value of the parameter that matches the input condition is equal to or less than a predetermined value. For example, when a destination point is specified as a condition for creating a drive plan, the navigation device 300 uses the driving history information that has the same point as the destination point specified as the destination point in the driving history information as similar driving history information. Judge. At this time, it may be determined as similar travel history information including travel history information that uses a feature of the same genre as the designated point as a destination point.

  In addition, when there are a plurality of conditions specified by the user, for example, a point is allocated to each parameter (a destination point, a stop point, a passenger, etc.) included in the travel history information, and the value is specified by the user. It may be determined whether or not they are similar by accumulating parameter points that match In this case, the navigation device 300 determines that the travel history information with the accumulated points equal to or greater than the predetermined value or the highest accumulated points is the similar travel history information. Further, for example, a priority order may be set for each parameter, and the travel history information that matches the value of the parameter with the highest priority order may be determined as similar travel history information.

  When there is similar travel history information (step S504: Yes), the navigation apparatus 300 determines the similar travel history information as travel history information to be referred to when creating a drive plan (step S505, method (1) above).

  On the other hand, when there is no similar travel history information (step S504: No), the navigation apparatus 300 performs statistical processing on the travel history information to calculate the user's drive preference information (step S506, method (3) above). The drive preference information is, for example, the value of parameters such as the stay time at the destination point, the stop-off point, the route used, etc., for the travel history information with the same destination point, and the mode value and average value are calculated. is there. Further, for example, the destination points may be ranked for each accompanying person, or the average value of the staying time may be calculated for a certain stop point.

  For example, the navigation device 300 calculates an average value for parameters that can calculate an average value, such as a stop time to a stop point and a required time of a predetermined section on a road. In addition, the mode value is calculated for parameters whose average value cannot be calculated, such as a destination point of a drive plan, a stopover point, and a road to be used. Thus, by performing statistical processing, it is possible to extract a user's drive preference from a plurality of travel history information. Note that this statistical processing may be performed in advance when the processing load of the CPU 301 is low, instead of performing when there is no similar travel history information (step S504: No).

  Then, the navigation apparatus 300 collates road traffic information and the like at the time of execution of the drive plan (step S507), and creates a drive plan according to the situation at the time of execution (step S508). At this time, the navigation apparatus 300 may create a plurality of drive plans. When the drive plan is executed, when the start time or end time of the drive plan is specified by the user, the time is the time at each point on the drive route based on the specified time. Further, when the departure time and end time are not designated, the time at each point on the drive route with respect to the current time is used.

  The navigation device 300 receives, for example, real-time road traffic information such as VICS (registered trademark) information or information uploaded from a vehicle actually traveling on the road via the communication I / F 315. Get road traffic information at the time of execution. In addition, the navigation device 300 may obtain a statistical value of past road traffic information included in map data or the like, and predict a road situation when the drive plan is executed. In addition to the road traffic information, the navigation device 300 may acquire weather information, information on facility congestion, and the like.

  When the travel history information referred to in step S505 is determined, the drive plan is created by changing the value of the parameter included in the travel history information in accordance with the road conditions when the drive plan is executed. Specifically, for example, the route to the destination point or the stop point is changed, or the stay time at the destination point or the stop point is adjusted.

  If the user's drive preference information is calculated in step S506, a drive plan that matches the user's drive preference is created in accordance with the road conditions when the drive plan is executed. Specifically, for example, a drive plan is created by combining the mode value of the route used when driving to a specified destination point, the mode value of the stop point, the average value of the stay time at the destination point, etc. . For parameter values that can be changed in the vicinity of the average value, such as the stay time at the destination point, change in the vicinity of the average value according to other parameter values (for example, the required time from the departure point to the destination point). May be.

  The navigation device 300 presents the drive plan created in step S508 to the user (step S509). For example, the navigation device 300 displays the contents of the created drive plan on the display 314. Further, for example, the content of the drive plan may be output from the speaker 310 as a sound. Thereby, the user can confirm the content of the created drive plan. Further, when a plurality of drive plans are created, the navigation apparatus 300 may display the contents of each drive plan and allow the user to select a drive plan to be executed.

  When the presented drive plan is approved by the user (step S510: Yes), the navigation apparatus 300 performs route guidance according to the approved drive plan (step S511), and ends the processing according to this flowchart. When a plurality of drive plans are presented in step S509, route guidance is performed according to the drive plan selected by the user. In addition, when the driving plan is not started immediately, such as when the execution time of the drive plan is designated as a future time, the navigation device 300 uses the approved drive plan data as the magnetic disk 305 and the like instead of performing route guidance. Recording is performed on the optical disk 307, and the processing according to this flowchart ends.

  On the other hand, when the presented drive plan is not authenticated by the user (step S510: No), the navigation apparatus 300 returns to step S508 and recreates the drive plan. At this time, the navigation device 300 re-creates the drive plan by changing, for example, the parameters of the previously created drive plan according to the user's drive preference.

  As described above, if a drive plan is created based on travel history information similar to the conditions specified by the user, the error between the required time in the drive plan and the actual required time can be reduced. The possibility that the drive plan can be executed as planned can be increased. In addition, it is possible to reduce the processing load such as searching for a stopover point. Moreover, if a user's drive preference is analyzed from driving | running history information and a drive plan is created based on an analysis result, the drive plan which reflected the user's preference can be created. In addition, although FIG. 5 demonstrated the process which combined the method of (1) and (3) mentioned above, you may make it perform only one of processes.

  Next, a description will be given of the process in the case of creating travel history information using the drive plan selected by the user (2). FIG. 6 is a flowchart showing another example of the drive plan creation process by the navigation device. The navigation apparatus 300 first waits until an instruction to create a drive plan is issued (step S601: No loop). When the creation of the drive plan is instructed (step S601: Yes), the navigation device 300 displays past travel history information on the display 314 (step S602).

  FIG. 7 is an explanatory diagram illustrating an example of a display screen of travel history information. The user selects travel history information to be referred to when creating the drive plan from the travel history information displayed as shown in FIG. The travel history information displayed in step S602 may be the user's own travel history information, or may be travel history information of a person other than the user (another user). Further, both the user's own travel history information and the travel history information of other users may be displayed. By being able to refer to the travel history information of other users, it is possible to increase the choices of drive plans.

  The travel history information of other users is acquired through, for example, the communication I / F 315 or a portable recording medium (the navigation device 300 reads data captured by a personal computer or the like). The travel history information 720 of other users may be widely disclosed on WEB or the like, or shared only by a predetermined group (for example, a group of users using the same manufacturer's navigation device). It may be what has been done. Further, the user's own travel history information may be made available to other users.

  In step S602, the navigation apparatus 300 may cause the user to input a part of the conditions used for creating the drive plan, and search for and display travel history information that conforms to the input conditions. In the example shown in FIG. 7, a result (search result display 700) of searching for travel history information whose destination point is “XX waterfall” is shown.

  The search result display 700 shows the travel history information 710 of the user himself and the travel history information 720 of a person other than the user. The user's own travel history information 710 and the travel history information 720 of a person other than the user are configured by a travel history ID 711, travel date information 712, course outline information 713, and required time information 714, respectively.

  The travel history ID 711 is an ID for identifying individual travel history information. The travel date information 712 is information indicating the date and time when the travel was performed. The course outline information 713 is information indicating an outline of the travel history information, and indicates, for example, a stop point or a destination point in the travel history information. The required time information 714 is information indicating the time required for traveling from the travel start point to the travel end point. The user can display more detailed information of the drive plan by pressing the details button 731.

  The search results can be sorted by pressing a date order button 732, a departure point button 733, a required time button 734, and a user preference button 735. For example, when the date order button 732 is pressed, the search results are sorted in the order of newest (or oldest) travel date. When the departure point button 733 is pressed, the search results are sorted in the order in which the travel start point is closer to the user's current point (or registered point such as home). When the required time button 734 is pressed, the search results are sorted in order of shorter (or longer) required time. When the user preference button 735 is pressed, the search results are sorted in the order suitable for the user's drive preference based on the drive preference information (see step S506 in FIG. 5) calculated from the user's own travel history data.

  In addition, a search result can be narrowed down by inputting an arbitrary character string into the character input box 736. For example, by inputting the name of the stop point in the character input box 736 and narrowing down, it is possible to search for the travel history information that stops at the input stop point and the destination point is “XX waterfall”. Moreover, you may enable it to search the driving | running | working history information which the other user's name by designating the name, ID, etc. of another user. For example, it is possible to create a drive plan more efficiently by referring to the travel history information of other users who are close to the area where they live or have similar drive preferences.

  Returning to the description of FIG. 6, the navigation apparatus 300 waits until the travel history information referred to when the drive plan is created is selected by the user (step S <b> 603: No loop). When the travel history information is selected (step S603: Yes), the navigation apparatus 300 collates road traffic information and the like at the time of execution of the drive plan (step S604), and creates a drive plan that matches the situation at the time of execution. (Step S605). Details of the processes in steps S604 and S605 are the same as those in steps S507 and S508 in FIG. That is, the drive plan is created by changing the value of the parameter included in the travel history information selected by the user in accordance with the road condition when the drive plan is executed.

  For example, when creating a drive plan using travel history information of another user, the travel start point and the travel end point are set to the user's home or the like, and the route is searched again. In addition, the staying time at the destination point or the stop point may be changed according to the companion composition of the user (for example, longer if there are children or elderly people). Similarly to step S506 in FIG. 5, the driving history information is statistically processed to calculate the user's drive preference information, and the drive plan is created in consideration of the drive preference information together with the situation when the drive plan is executed. May be.

  Next, the navigation apparatus 300 presents the drive plan created in step S605 to the user (step S606). When the presented drive plan is approved by the user (step S607: Yes), the navigation apparatus 300 performs route guidance according to the approved drive plan (step S608), and ends the processing according to this flowchart. On the other hand, when the presented drive plan is not authenticated by the user (step S607: No), the navigation apparatus 300 returns to step S605 and recreates the drive plan.

  Thus, if the driving history information is presented to the user and the drive plan is created using the driving history information selected by the user, the time and effort for the user to input the conditions can be reduced. In addition, since the drive plan can be created using the travel history information of other users, the range of options for the drive plan can be expanded.

  As described above, the navigation device 300 records the travel history information of the vehicle and creates a drive plan by changing the parameters according to the conditions specified by the user. As a result, the error between the parameter value in the drive plan (for example, the required time and stay time at the destination) and the actual value can be reduced, and the possibility that the drive plan can be executed as planned is increased. As well as the processing load when creating a drive plan.

  In addition, if the driving history information is presented to the user and the drive plan is created using the movement history information selected by the user, it is possible to reduce the effort for the user to input the driving plan conditions. Further, by statistically processing the travel history information and creating a drive plan using an average value of parameters under a specified condition, a drive plan reflecting the user's preference can be created. In addition, if the road traffic information at the time of executing the drive plan is used when creating the drive plan, the error between the required time in the drive plan and the actual required time can be reduced, and the drive plan is executed as planned. The possibility of being able to be increased can be increased.

  Moreover, since the navigation apparatus 300 can create a drive plan using the movement history information of the vehicle on which the navigation apparatus 300 is mounted, the user's preference can be reflected in the drive plan. In addition, since the navigation device 300 can create a drive plan using travel history information of vehicles other than the vehicle on which the device itself is mounted, the range of drive plan options can be expanded.

  In this embodiment, the drive plan is created by the navigation device 300. However, the present invention is not limited to this, and the drive plan may be created by an information processing device such as a personal computer or a mobile phone terminal. When it is desired to use the drive plan data created by the information processing apparatus in the navigation apparatus 300, for example, the drive plan data may be transmitted to the navigation apparatus 300 via a network. Further, for example, the drive plan data can be used in the navigation device 300 by recording the drive plan data in a portable recording medium such as a USB memory or an SD card, and causing the navigation device 300 to read the recorded data.

  The drive plan creation method described in this embodiment can be realized by executing a program prepared in advance on a computer such as a personal computer or a workstation. This program is recorded on a computer-readable recording medium such as a hard disk, a flexible disk, a CD-ROM, an MO, and a DVD, and is executed by being read from the recording medium by the computer. The program may be a transmission medium that can be distributed via a network such as the Internet.
