Description

  The present invention relates to an in-vehicle navigation device that guides a vehicle to a destination according to a guidance route, and in particular, an in-vehicle navigation device having a function of displaying detailed information of various facilities existing around the guidance route on a map. About.

  The in-vehicle navigation device is a map data storage device such as a DVD (Digital Versatile Disk) -ROM that stores map data, a display device, a gyro, a GPS (Global Positioning System) receiver, and a current position of the vehicle such as a vehicle speed sensor. And a vehicle movement detection device for detecting the current direction. Then, map data including the current position of the vehicle is read from the map data storage device, a map image around the vehicle position is displayed on the screen of the display device based on the map data, and a vehicle position mark (location) is displayed on the map image. The map image is scrolled and displayed as the vehicle moves, or the map image is fixed on the screen and the vehicle position mark is moved so that you can see where the vehicle is currently traveling. It is made to understand with.

  In general, the in-vehicle navigation device is equipped with a route guidance function that allows the user to easily travel to a desired destination without making a mistake on the road. According to this route guidance function, the optimum route connecting from the starting point to the destination is automatically searched by performing simulation calculation such as horizontal search method or Dijkstra method using the map data, and the searched route is used as the guide route. Remember, while driving, draw the guidance route on the map image with a different color from other roads and display it on the screen, or within a certain distance to the intersection where the vehicle should change the course on the guidance route When approaching, the user is guided to the destination by drawing an arrow indicating the course at the intersection where the course should be changed on the map image and displaying it on the screen.

  When searching for a route, the user sets a destination in advance, and sets a waypoint on the way to the destination as necessary. If necessary, various conditions (whether toll road priority or general road priority) are also set. In the navigation device, a plurality of routes to the destination are searched based on these set data, and the searched routes are displayed in different colors, for example, according to one route selected by the user. Give guidance.

In such a navigation device, a map is displayed on a display screen, and detailed information of facilities in the range where the map is displayed is displayed. For example, Patent Literature 1 discloses a technique for displaying detailed information about a facility on a display screen so as not to overlap with the current position and travel route.
Japanese Patent Laid-Open No. 11-3032

  However, in the invention described in Patent Document 1, since detailed information is displayed for all facilities displayed along the guidance route, depending on the number of displayed facilities, the display content (detailed information) may be displayed. There is inconvenience that it is hard to understand.

  Further, detailed information is displayed on the display screen regardless of the vehicle speed regardless of whether the vehicle is traveling at a high speed or a low speed. For this reason, when detailed information on the surrounding facilities is displayed on the screen while the vehicle is traveling at a high speed, there is no particular problem for a person other than the driver (for example, a passenger in the passenger seat) to see the detailed information. Inconvenience occurs when the driver sees it. That is, for the driver, even if the detailed information of the facility is displayed on the screen during high-speed traveling, it is difficult to visually recognize the detailed information, and there is a problem from the viewpoint of safety. Furthermore, when the number of peripheral facilities displayed on the screen is large, there is a problem that it becomes more difficult to obtain necessary information from the detailed information.

  The present invention has been made in view of the problems of the prior art, and is to provide an in-vehicle navigation device capable of displaying detailed information on facilities according to the speed of a vehicle.

In order to solve the above-described problems of the prior art, according to the basic form of the present invention, display means for providing guidance information on a screen, memory means for storing information relating to map data and various facilities, and vehicle speed are detected. Display range memory storing a display range table representing a correspondence relationship between a vehicle speed detection means and a display range in which a vehicle speed set in advance and a range in which detailed facility information is displayed are indicated by a distance from the vehicle position. And a control means operatively connected to the display means, the memory means , the vehicle speed detection means and the display range storage means , the display range table for a plurality of stages of vehicle speed from low speed to high speed. , the distance from the vehicle position as faster than the low speed is set longer, the control means, and determines that the vehicle speed detected is below a predetermined speed by the vehicle speed detecting means , Referring to the display range table, the range to be displayed to determine the property details, the acquired information from the memory means related to facilities that exist in the range, on the screen of the display means, and the obtained A vehicle-mounted navigation device is provided that displays the detailed information together with the name of the facility in association with the location of the facility.

  In the present invention, the vehicle speed is detected by the in-vehicle navigation device, and the detailed information of the facility is displayed when the vehicle speed falls below a specified speed. The specified speed is, for example, 30 km / h. The range for displaying the detailed facility information is determined with reference to a display range table in which the relationship between the vehicle speed and the range for displaying the detailed facility information is set. In this display range table, a range for displaying detailed facility information for a plurality of vehicle speeds is defined.

  Thus, since the detailed information of the facility is displayed on the screen only when the vehicle is traveling at a low speed, the driver who is traveling at a low speed can visually recognize the detailed information of the facility relatively safely. . Further, when the vehicle is not traveling at a low speed, the detailed information of the facility is not displayed on the screen, so that it is possible to avoid the inconvenience that it becomes difficult to see necessary information.

  The in-vehicle navigation device according to the above aspect further includes own vehicle position detection means for detecting the current position of the own vehicle, and the display range table stored in the display range storage means travels in an urban area. Data indicating a range for displaying detailed information of the facility for each vehicle speed for each of the case where the vehicle is traveling and the case where the vehicle is traveling outside the urban area, and the control unit is responsive to the vehicle position detected by the vehicle position detection unit. Then, referring to the vehicle speed and the display range table, a range for displaying the detailed information of the facility may be determined.

  In the present invention, the detailed information of the facility is displayed on the screen when the vehicle is traveling at a low speed, but the detailed information of the facility is displayed depending on whether the vehicle is traveling in an urban area or a non-urban area. The display range is specified separately. Therefore, when displaying a map of an urban area with a large display scale ratio on the screen, specify a narrow range for displaying detailed information of the facility, and when displaying a map other than an urban area with a small display scale ratio on the screen Can specify a wide range for displaying the detailed information of the facility.

  Further, in the in-vehicle navigation device according to the above aspect, the control means is a facility facing a road of a guidance route displayed on the screen of the display means, and the facility existing forward from the vehicle position You may make it display the name and detailed information about on the screen of the said display means.

  In the present invention, facilities that display detailed information are limited to facilities that face the road on which the guidance route is displayed and that are ahead of the vehicle. For this reason, since the number of detailed information of the displayed facility is limited, the display screen is easy to see.

(Detailed display of facilities)
Hereinafter, the detailed information display processing of the facility performed by the vehicle-mounted navigation device according to the present embodiment will be described with reference to FIGS. 3 and 4 showing an example of the processing flow.

  First, in step S11, a route search destination is acquired. The destination is set by a user (for example, a driver) by an input operation from the operation unit 2.

  In the next step S12, a route search is performed. The route search is based on the input destination data and the departure point data set based on the current position of the vehicle detected based on the output signals of the GPS receiver 5 and the autonomous navigation sensor 6. The map data in the range from the ground to the destination and the road data for route search are read from the DVD 1 to the buffer memory 12 by controlling the DVD controller 11, and the data stored in the guidance route storage unit 21 is further referred to. Then, a guidance route connecting the shortest distance from the departure point to the destination is searched by a horizontal search method or the like. The search result is stored in the guide route storage unit 21.

  In step S13, route guidance is performed. The route guidance provides the route guidance information based on the route search result of step S12 to the user via the screen of the display device 7.

  In the next step S14, it is determined whether or not the route guidance is terminated. That is, when the power switch is turned off or when the navigation device is not in use, the process is terminated, and in other cases, the process proceeds to step S15.

  In the next step S15, it is determined whether the vehicle is traveling in an urban area or a place other than the urban area. If it is determined that the host vehicle is traveling in an urban area, the process proceeds to step S16. If it is determined that the host vehicle is traveling in a place other than the urban area, the process proceeds to step S22. The control unit 18 detects the current position of the vehicle from the GPS signal received by the GPS receiver 5 and the signal input from the autonomous navigation sensor 6, and refers to the map data read from the DVD 1 to the buffer memory 12. Then, it is determined whether or not the vehicle is traveling in the city.

  In the next step S16, the traveling speed is detected by the self-contained navigation sensor 6.

  In the next step S17, it is determined whether or not the traveling speed of the vehicle is 30 km / h or less. When the determination result is NO (travel speed is greater than 30 km / h), route guidance is continued without displaying the detailed information of the facility.

  When the traveling speed is 30 km / h or less, the process proceeds to step S18, and the range in which the detailed information of the facility is displayed is specified. That is, the control unit 18 uses the correspondence relationship between the vehicle speed stored in the speed-display range table storage unit 25 and the display range indicating the range in which the detailed information of the facility is displayed according to the distance from the own vehicle, Based on the vehicle speed detected in step S16, a range for displaying the detailed information of the facility is extracted.

  In this embodiment, the range in which the detailed information of the facility is displayed is defined by dividing the traveling speed of the vehicle into three stages. When the traveling speed is 10 km / h or less, the process proceeds to step S19, and when the traveling speed exceeds 10 km / h and is 20 km / h or less, the process proceeds to step S20 and the traveling speed exceeds 20 km / h to 30 km. If it is less than / h, the process proceeds to step S21.

  In step S19, the detailed information of the facility is displayed together with the facility name for the facility that faces the road on the guide route on which the own vehicle is displayed and is within 30 m from the own vehicle. For the detailed information on the facility, the control unit 18 searches the detailed information on the facility read from the DVD 1 to the buffer memory 12, and displays the detailed information on the facility in the above range on the display screen.

  In step S20, in the same manner as in step S19, the detailed information of the facility is displayed together with the facility name of the facility facing the road on the guidance route on which the own vehicle is displayed and within a range of 100 m from the own vehicle. Display on the display screen.

  In step S21, as in step S19 and step S20, the facility facing the road on the guide route on which the vehicle is displayed and within a range of 200 meters from the vehicle is listed with the facility name of the facility. Display detailed information on the display screen.

  The route guidance is continued even after the detailed information on the facility is displayed in step S19, step S20 or step S21, and the detailed information on the facility is displayed according to the position and speed of the host vehicle.

  On the other hand, if it is determined in step S15 that the vehicle is traveling in a place other than the city, the process proceeds to step S22, and the vehicle speed is detected in the same manner as in step S16.

  In step S23, it is determined whether the vehicle speed is 60 km / h or less. When the determination result is NO (travel speed is greater than 60 km / h), route guidance is continued without displaying the detailed information of the facility.

  When the traveling speed is 60 km / h or less, the process proceeds to step S24, and the range in which the detailed information of the facility is displayed is specified. That is, the control unit 18 uses the correspondence relationship between the vehicle speed stored in the speed-display range table storage unit 25 and the display range indicating the range in which the detailed information of the facility is displayed according to the distance from the own vehicle, Based on the vehicle speed detected in step S22, a range for displaying the detailed information of the facility is extracted.

  In the present embodiment, even when the vehicle is traveling in a place other than an urban area, the range in which the detailed information is displayed is defined by dividing the traveling speed of the vehicle into three stages. If the traveling speed is 20 km / h or less, the process proceeds to step S25. If the traveling speed exceeds 20 km / h and is 40 km / h or less, the process proceeds to step S26, and the traveling speed exceeds 40 km / h to 60 km. If it is less than / h, the process proceeds to step S27.

  In step S25, detailed information on the facility is displayed together with the facility name for the facility that faces the road on the guidance route on which the vehicle is displayed and is within 100 meters from the vehicle. At this time, the detailed information on the facilities may not be displayed at the same time for all the facilities within a range of 100 m from the own vehicle, but the detailed information on the facilities may be displayed, for example, five by five. As in step S19, the detailed information on the facility is retrieved by the control unit 18 from the DVD 1 to the buffer memory 12, and the detailed information on the facility within the above range is displayed. Display on the screen.

  In step S26, for a facility that faces a road on the guidance route on which the vehicle is displayed and is within a range of 100 m or more and 500 m or less from the vehicle, detailed information on the facility is provided along with the facility name of the facility as in step S25. Is displayed.

  In step S27, in the same manner as in steps S25 and S26, the detailed information of the facility is displayed together with the facility name of the facility in the range of 500 m to 1 km from the own vehicle.

  The route guidance is continued even after the detailed information of the facility is displayed in step S25, step S26 or step S27, and the detailed information of the facility is displayed according to the position and speed of the own vehicle.

  In general, when traveling in a place other than an urban area, the speed is higher than when traveling in an urban area. Therefore, in this embodiment, although the speed used as the reference | standard which displays the detailed information of a facility was set to 60 km / h, the reference | standard can be changed suitably.

  Moreover, in this embodiment, although the distance range which displays the detailed information of a facility when the speed of the vehicle in a city area is 10 km / h, 20 km / h, and 30 km / h has been described as 30 m, 100 m, and 200 m, respectively, The correspondence between the speed stored in the speed-display range table storage unit and the distance range of the facility displaying the detailed information can be changed as appropriate by operating the operation unit 2. The correspondence relationship between the speed referred to when traveling outside the city area and the distance range of the facility displaying the detailed information can be similarly changed.

  Moreover, in this embodiment, although the example which displayed the display of the facility planarly was shown, it is also possible to apply to the screen which displayed the facility three-dimensionally.

  Further, in the present embodiment, the detailed information of the facility has been described as being included in the navigation device when the detailed information is displayed. However, the detailed information of the facility is held via the communication device 3 from the outside of the vehicle. It is also possible to display the detailed information of the facility obtained from a service center or the like.

  As described above, in the vehicle-mounted navigation device according to the present embodiment, the vehicle speed is detected, and the detailed information on the facility is displayed when the vehicle speed falls below a specified speed. The specified speed is, for example, 30 km / h. The range for displaying the detailed facility information is determined with reference to a display range table in which the relationship between the vehicle speed and the range for displaying the detailed facility information is set. In this display range table, a range for displaying detailed facility information for a plurality of vehicle speeds is defined.

  Thus, since the detailed information of the facility is displayed on the screen only when the vehicle is traveling at a low speed, the driver who is traveling at a low speed can read the detailed information of the facility relatively safely. Further, when the vehicle is not traveling at a low speed, the detailed information of the facility is not displayed on the screen, so that it is possible to avoid the inconvenience that it becomes difficult to see necessary information.

  In the present embodiment, the range in which the detailed information of the facility is displayed is defined separately depending on whether the vehicle is traveling in an urban area or a vehicle other than an urban area. Therefore, when displaying a map of an urban area with a large display scale ratio on the screen, specify a narrow range for displaying detailed information of the facility, and when displaying a map other than an urban area with a small display scale ratio on the screen Can specify a wide range for displaying the detailed information of the facility.

  Furthermore, in this embodiment, the facility for displaying the detailed information is limited to the facility facing the road on which the guidance route is displayed and located in front of the position of the own vehicle. For this reason, since the number of detailed information of the displayed facility is limited, the display screen is easy to see.
