  Next, a travel history display device according to an embodiment of the present invention will be described in detail with reference to the drawings. Here, as one preferred embodiment, the travel history when the vehicle actually travels is acquired by the navigation device, the travel history data is uploaded to the server, the user accesses the server, and the web screen An example of a system for browsing the history check map will be described.

  FIG. 1 is a diagram illustrating a schematic configuration of a travel history display device according to an embodiment of the present invention. The travel history display device 10 of this embodiment includes a navigation device 30 that generates travel history data, a server 20 that registers travel history data generated by the navigation device 30, and a history that includes access to the server 20 and includes travel history data. And an information processing terminal 40 for browsing the confirmation map.

  FIG. 2 is a block diagram showing a typical configuration of the navigation device. The navigation device 30 includes a self-contained navigation sensor 100 such as a gyro sensor or a distance sensor, a GPS receiver 102 that receives a signal from a GPS satellite and detects the position of the vehicle, and a VICS that receives road traffic information distributed from a VICS center. Audio is output from the receiver 104, the input unit 106 that receives input from the user, the communication control unit 108 that enables data communication with the server 20 wirelessly or by wire, the storage unit 110 that stores road map data, and the like. Audio output unit 112, display control unit 116 for displaying road map and the like on display 118, program memory 120 for storing program, data memory 130 for temporarily storing data, control unit for controlling each unit by executing program 140 is comprised.

  The road map data stored in the storage unit 110 includes link data for identifying roads, node data for identifying intersections, facility data for identifying POIs such as facilities, and the like. The link data includes information such as lane information including identification of a dedicated lane such as a right or left turn, the maximum speed set for the link, the radius of curvature of the link, and whether or not there is a pause. As will be described later, these pieces of information are used for determining whether or not the vehicle is in danger driving when collecting the traveling history of the host vehicle.

  The program memory 120 searches for a vehicle position calculation program 122 that calculates the vehicle position based on detection signals from the self-contained navigation sensor 100 and the GPS receiver 102, and an optimal route from the vehicle position and other positions to the destination. And a travel history data generation unit 126 that collects a travel history of the host vehicle and generates travel history data. The data memory 130 stores road map data 132 around the vehicle position read from the storage unit 110, calculated vehicle position information 134, travel history data 136, and the like.

  FIG. 3 is a functional block diagram of the travel history data generation unit 126. The travel history data generation unit 126 identifies a display mode storage unit 200 that stores the display mode of the road map on the display 118 when the host vehicle is traveling, and an intersection or link that identifies and records the intersection or link that the host vehicle has traveled. Recording unit 210, dangerous traveling determination unit 220 for determining whether or not the vehicle is dangerous traveling, dangerous traveling point recording unit 230 for recording a point determined to be dangerous traveling, and a cause that is determined to be dangerous traveling A dangerous traveling cause recording unit 240, a traveling history data creating unit 250 that creates traveling history data when traveling of the host vehicle is completed, and an upload unit 260 that uploads the created traveling history data to the server 20.

  FIG. 4 is a flowchart for explaining the operation of the travel history data generation unit 126. When the travel of the host vehicle is started, or when the travel of the host vehicle is started and the user gives an instruction to create travel history data (step S101), the display mode storage unit 200 is set to the display 118. The displayed display mode is stored (step S102). The display mode includes whether the road map is displayed in 2D (2D) or 3D (3D), in 2 screens, whether the map orientation is north up or heading up, etc. Information is stored.

  When the vehicle starts running, the vehicle position is calculated by the vehicle position calculation program 122, road map data around the vehicle position is read from the storage unit 110, and a road map is displayed on the display 118. . The own vehicle position is synthesized on the road by a method such as map matching, and the road map is scrolled as the own vehicle moves. The link / intersection recording unit 210 identifies the map-matched link and the intersection, and records them (step S103). By sequentially connecting the recorded links and intersections, a travel history can be obtained.

  The dangerous traveling determination unit 220 monitors driving during traveling and determines whether or not dangerous traveling is included (step S104). Whether or not the vehicle is traveling dangerously is determined by comparing the information obtained from the road map data with the traveling state of the vehicle. For example, when the legal speed set for the link is compared with the speed of the vehicle and the legal speed is exceeded, or when the right / left turn direction set for the link is different from the traveling direction of the vehicle, or the link When the vehicle is not decelerated due to the temporary stop set at the time, or when there is sudden acceleration or braking, it is determined that the vehicle is traveling dangerously.

  When the dangerous traveling is determined, the dangerous traveling point recording unit 230 records the point where the dangerous traveling has occurred (step S105). The location record may be absolute coordinates of latitude and longitude, or an identifiable coordinate position on a link or intersection. Further, the dangerous driving cause recording unit 240 records the cause determined to be dangerous driving in association with the point. As the cause, at least one cause can be selected from a plurality of causes prepared in advance, and the cause can be encoded information.

  The travel history data generation unit 126 determines whether or not the travel of the host vehicle has been stopped, or whether or not there has been an input by the user to stop the collection of travel history data (step S106). When traveling is continued, the processing from step S103 is repeated. When it is determined that the travel is finished, the travel history data creation unit 250 creates travel history data in which a series of recorded links, intersections, and other travel histories and information on dangerous travels are integrated (step S107).

  FIG. 5 is a configuration example of travel history data. The travel history data includes, for example, the start date and time of travel, the departure place (including the city name, street name, and the start point when searching for routes), and the arrival place (city name, street name, when searching for routes) ), Identification information of the series of links and intersections that the vehicle has traveled, the speed of the vehicle related to the links that were traveled, dangerous events related to dangerous travel (dangerous travel locations and causes), Includes the display mode set on the display when the vehicle is running.

  Once the travel history data has been created, the upload unit 260 then uploads the travel history data to the server 20 (step S108). For uploading to the server 20, as is well known, processing such as user login is performed, and then the travel history data is stored in a storage area assigned to the own account.

  FIG. 6 is a block diagram showing the configuration of the server 20. The server 20 includes a data communication unit 22 that communicates with the navigation device 30, the information processing device 40, and other computers via a network, a database 24, and an arithmetic processing unit 26 that performs various arithmetic processes according to programs and the like. And a memory 28 for storing programs and the like. In the present embodiment, the arithmetic processing unit 26 stores the travel history data in the database 24 according to the program or provides the user with a history confirmation map generated based on the travel history data in response to a request from the user.

  When there is a request for uploading travel history data from the navigation device 30, the arithmetic processing unit 26 stores the travel history data in the database 24. Preferably, the arithmetic processing unit 26 creates a travel history list in order to facilitate management of travel history data stored in the database 24. FIG. 7 shows an example of the travel history list. As shown in the figure, the travel history list includes management information such as a user ID, a travel history ID, a travel date and time, a departure place, and an arrival place. When the travel history data is uploaded from the user, the list is updated. .

  Next, the operation | movement which displays the log | history confirmation map which reflected the driving | running history using the driving | running | working history data stored in the server 20 using the information processing apparatus 40 is demonstrated. The information processing apparatus 40 includes a personal computer, a network computer, and the like. The information processing apparatus 40 typically includes an input unit that receives an instruction from a user, a display unit, a data communication unit that performs data communication with the server 20, and each unit. The control part etc. which control are provided.

  As shown in FIG. 8A, the information processing apparatus 40 accesses the server 20 and logs on using a user ID or the like. The server 20 searches for a matching user ID from the travel history list shown in FIG. 7 using the logged-on user ID, and transmits the travel list including the searched user ID to the information processing apparatus 40. The travel history list is displayed on the display unit of the information processing apparatus 40, and the user selects a travel history ID to be confirmed from the travel history list and transmits it to the server 20.

  Upon receiving the travel history ID, the server 20 searches the database 24 for relevant travel history data (FIG. 5), generates a history confirmation map based on the travel history data, and transmits this to the information processing device 40. FIG. 9 shows a history check map MP displayed on the display unit of the information processing apparatus 40. The history confirmation map MP is displayed so that the map orientation is north up, and the travel history P of the vehicle (shown by a thick solid line in the figure) is drawn there. Further, on the map, icons D1, D2, and D3 indicating dangerous driving are drawn at points determined as dangerous driving. The icons D1 to D3 are displayed based on the points recorded by the dangerous driving point recording unit 230.

  By clicking an area (indicated by R in the drawing) or icons D1 to D3 in the history confirmation map MP, the detailed map in which the dangerous event area is enlarged can be viewed. When the selection information of the dangerous event area by the user is transmitted to the server 20, the server 20 generates a detailed history confirmation map in which the dangerous event area is enlarged. At this time, the server 20 determines the orientation of the enlarged history confirmation map based on the display mode included in the travel history data. For example, when the display mode when the host vehicle is traveling (acquisition of traveling history) is set to heading up, the enlarged history confirmation map is converted to heading up and transmitted to the information processing device 40. Thereby, the information processing apparatus 40 displays the enlarged history confirmation map with heading up.

  FIG. 10B shows a display example of the enlarged history confirmation map of the present embodiment. Here, it is assumed that the area R including the dangerous event D1 in FIG. 9 is selected. The enlarged history confirmation map is displayed in a heading-up, and the cause Q of dangerous driving is added in addition to the dangerous driving icon D1. The cause Q is based on the record of the dangerous driving cause recording unit 240. The cause is a message that “Only a right turn lane can be reached by a traffic light but it is judged that it is dangerous because it has gone straight”. Since it is displayed in a heading-up, it is possible to instantly understand the positional relationship of a right turn when looking back on the driving of the vehicle. On the other hand, FIG. 10A is based on the conventional method, and the enlarged history confirmation map is displayed in the same north up as the orientation of the history confirmation map shown in FIG.

  Further, the server 20 does not necessarily desire the heading-up when the display mode when the host vehicle is traveling (acquisition of traveling history) is set to north up, so FIG. ), A selection screen as to whether or not to set the heading up is transmitted to the information processing apparatus 40. The information processing apparatus 40 displays a selection screen and transmits a selection result from the user to the server 20. Based on the selection result, the server 20 transmits either the north up or heading up enlarged history check map to the information processing apparatus 40.

  Next, another example of the method for determining the orientation of the enlarged history confirmation map will be described. FIG. 11 shows a table for determining the orientation of the enlarged history confirmation map. The table is stored in the memory 28 of the server 20, and the arithmetic processing unit 26 can determine the orientation with reference to the table. When the display mode of the navigation device 30 is set to 2D (two-dimensional), normal view, and heading up, the enlarged history check map is automatically set to heading up. This is because the actual travel direction and the map orientation are the same. If it is set to north up, it is set to north up or heading up according to the user option as shown in the flow of FIG. 8B. This is because it may be better for the user not to convert the map orientation. The same determination is made when the display mode is 2D, city map, or sky view.

  When the display mode is set to 3D (3D) and driver's view, the orientation of the enlarged history check map is determined to be heading up. This is because the heading-up is almost the same as the direction of the driver view. When the display mode is a two-screen display, the main screen is 2D, and the sub-screen is 2D, the orientation setting of the main screen is followed. If the main screen and the sub screen are not set, the larger screen area is set as the main screen, or the larger scale ratio is set as the main screen. Further, when the display mode is a two-screen display and 3D is included in either the main screen or the sub screen, the heading up is determined. That is, 3D is regarded as a main screen and 3D is set as a default.

  Next, another embodiment of the present invention will be described. In the above example, the location and cause of dangerous driving are displayed on the history confirmation map. Furthermore, when driving with a destination or waypoint set, a reroute (maximum search) is performed. In such a case, the reroute point may be recorded and placed, and when the history confirmation map is displayed, it may be displayed with an icon or the like so that the reroute point can be understood. For example, when a landmark on the route is missed, re-routing may be performed, so that the landmark is not missed during the next run.

  Further, when a CD, DVD, or other content is played back while traveling, the location where the content is played back is recorded, and an icon or the like may be displayed on the history confirmation map so that the location where the content is played back can be seen. . In this case, the icon can be changed according to the type of content (CD, DVD, etc.), or an icon that can be identified according to the content (such as the order of music) can be displayed. For example, playback content in a landscape area on the route (a point where the sea can be seen, a point where cherry trees can be seen, etc.) can be confirmed and used for a content playback program during the next run.

  Furthermore, the section using the hands-free telephone and the other party of the call during the running may be recorded, and an icon or the like for identifying the call section and the other party may be displayed on the history confirmation map. You can see when and who you have called.

  Next, another configuration example of the history information display device according to the embodiment of the present invention will be described. In the aspect shown in FIG. 1, the travel history data logged by the navigation device 30 is uploaded to a server, and the travel history map is displayed via a web screen from a personal computer such as a home. The navigation device 30 may display a history confirmation map based on the travel history data logged by itself.

  Furthermore, as shown in FIG. 12A, the travel history display device 10A transmits the travel history data logged in the navigation device 30 to the information processing device 40 such as a personal computer using wireless or wired communication means. Then, the history confirmation map may be displayed on the information processing apparatus 40. In this case, the information processing apparatus 40 is equipped with a program for displaying a history confirmation map, and has a history confirmation map display function similar to that of the server 20 described above. Further, as shown in FIG. 12B, the travel history data generated by logging in the navigation device 30 is stored in a removable recording medium (for example, a USB memory) 32, and the recording medium 32 is stored in a personal computer. The information processing apparatus 40 such as a computer may be attached and the history confirmation map may be displayed on the information processing apparatus 40. The travel history display device of the present invention is not limited to a single device, but is interpreted synonymously with a travel history display system including a plurality of devices.

  The preferred embodiment of the present invention has been described in detail above, but the present invention is not limited to the specific embodiment, and various modifications can be made within the scope of the present invention described in the claims. Deformation / change is possible.
