Description

  The present invention relates to a navigation apparatus that displays information extracted from search history and travel route history data in response to a user request on a screen.

  The navigation device searches a plurality of routes from the departure point to the destination set by the user, and selects and selects, for example, the best condition regarding conditions such as required time, travel distance, toll, road type, and driving performance. Guidance is performed based on one route. It is difficult to determine whether or not the route selection is truly the best for the user without actually traveling the searched plurality of routes. This is because, for example, even if a route that is estimated to have the shortest required time is selected, the actual required time may vary greatly due to the large number of traffic lights, or there may be a traffic jam that is considered when searching for a route. This is because there may be a difference. Therefore, in addition to the current position of the host vehicle that travels on the selected route, a navigation device that displays the virtual current position of the host vehicle when it is assumed that the other route searched for travels is also known. (Patent Document 1).

  With reference to FIGS. 1-9, one Embodiment which mounted the navigation apparatus by this invention in the vehicle is described. FIG. 1 is a diagram illustrating a configuration of a navigation device according to the present embodiment.

  The CPU 110 is an arithmetic processing unit that controls the entire navigation apparatus 100, and the CPU 110 and its peripheral circuits are connected to each other via a bus. The peripheral circuit includes a main storage device 115, an auxiliary storage device 140, a display module 150, and a broadcast tuner 160. The main storage device 115 has a work memory that is a work area of the CPU 110 and a program memory in which a control program is stored.

  CPU 110 receives signals from current position detection device 120, user input device 130, ETC on-board unit 170, wiper drive control circuit 180, and fuel injection amount calculation circuit 190. The current location detection device 120 includes, for example, a gyro sensor, a GPS (Global Positioning System) sensor, and a vehicle speed sensor. The user input device 130 is, for example, a touch panel, a push button switch around the panel, a joystick, or a remote controller. The ETC vehicle-mounted device 170, the wiper drive control circuit 180, and the fuel injection amount calculation circuit 190 will be described later.

  The auxiliary storage device 140 is a storage device that stores road map data and POI (Point of Interest or various facilities) information used for navigation processing. As the auxiliary storage device 140, for example, a hard disk drive, a CD or DVD in which road map data is stored, a flash memory, other recording media, and a reading device thereof can be used.

  The road map data is information relating to a map, and includes map display data, route search data, and guidance data in addition to road data. The map display data is data for displaying the road and the background of the road map. The route search data is data including branch information that is not directly related to the road shape, and is mainly used when calculating a recommended route (route search). The guidance data is data including intersection name, road name, direction name, and direction guide facility information, and is used when the user is guided based on the calculated recommended route. The road map data further includes information on tolls on toll roads, information on toll gates on toll roads where ETC (Electronic Toll Collection) is maintained, and toll discount information. The toll discount information includes information on a road where the toll discount can be received and information on conditions (time zone, travel distance, etc.) for receiving the toll discount on the road.

  In the road data included in the road map data, one road is represented as link string data by defining an intersection or the like as a node and defining a node as a link. Therefore, the link string data is composed of node data and link data. In the road data, node data and link data are classified and stored in mesh area units together with mesh codes. The mesh area refers to each divided area when the road map is divided into predetermined ranges. In the mesh code storage area, a number for identifying the mesh area is stored. In the storage area of the link string data, the position coordinates of the nodes, the link numbers between the nodes, and the position coordinates of the interpolation points that further divide the links are stored in the respective areas. These position coordinates are used as shape data for map display and locator processing.

  When a traffic signal is installed at the intersection, the node data of the intersection includes traffic signal installation information. The link data includes, for example, information on the number of lanes, road width, road type, toll gate, and level crossing regarding the road between nodes.

  Further, the auxiliary storage device 140 stores the route used for route guidance in the past together with detailed information to be described later including the travel date, departure time, arrival time, departure place, and arrival place. In the auxiliary storage device 140, a route that is not used for route guidance among routes calculated by route search includes a route search setting date, a departure setting time, an estimated arrival time, a departure point, and a destination, which will be described later. Stored with detailed information. The auxiliary storage device 140 further stores a travel locus when neither route guidance nor route search is performed, together with detailed information to be described later including the travel date, departure time, arrival time, departure location, and arrival location. The

  The display module 150 displays image data including characters and graphics output from the CPU 110 on the panel 155. The broadcast tuner 160 is used for receiving traffic information from a broadcast station or a VICS (registered trademark) center via an antenna. The wireless communication device 200 is, for example, a wireless communication module compliant with a wireless LAN standard such as IEEE standard 802.11 (Wi-Fi) or IEEE standard 802.16 (WiMAX), or a mobile phone communication module. When the wireless communication device 200 is a mobile phone, for example, the navigation device 100 includes a mobile phone connection interface, and the mobile phone is connected to the navigation device via the mobile phone connection interface.

  The ETC vehicle-mounted device 170 performs wireless communication with a roadside antenna provided at a toll gate, and when entering a toll road, transmits information on the toll gate entrance and then receives toll information. Fees for fee information are charged and paid to the user at a later date.

  CPU 110 receives from wiper drive control circuit 180 a signal regarding whether or not the wiper of the vehicle on which navigation device 100 is mounted is operating. It is estimated that it is raining while the wiper is operating.

  CPU 110 obtains data related to the fuel injection amount of the vehicle on which navigation device 100 is mounted from fuel injection amount calculation circuit 190. Accumulation of the fuel injection amount is started when the vehicle starts traveling, and the fuel consumption from departure to arrival can be calculated when the vehicle arrives at the destination.

  When a request for searching for a route stored in the auxiliary storage device 140 is input to the navigation device 100 via the user input device 130, the CPU 110 searches the route stored in the auxiliary storage device 140 and displays the search result. It is displayed on the screen of panel 155 as a travel route list. A screen display example of the travel route list is shown in FIG. In FIG. 2, traveling histories of a plurality of traveling routes are displayed in order of time series of traveling days. That is, the departure time, arrival time, departure place, and arrival place of each travel route are displayed in a list format.
