Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
Embodiment 1 FIG.
FIG. 1 is a block diagram showing a functional configuration of a navigation system according to Embodiment 1 of the present invention. This navigation system includes a position detection means 10, a map information acquisition means 20, an input means 30, a control means 40, and an output means 50.

  The position detection means 10 detects the current position of the vehicle on which the navigation system is mounted. Although not described in detail, the position detection means 10 is composed of an orientation sensor, a distance sensor, a GPS receiver, and the like. Current position data representing the current position of the vehicle detected by the position detection means 10 is sent to the control means 40.

  The map information acquisition means 20 is, for example, from a storage medium such as a CD-ROM (Compact Disc-Read Only Memory), DVD-ROM (Digital Versatile Disk-Read Only Memory) or HDD (Hard Disk Drive), or an external server. Get map information. The map information acquired by the map information acquisition means 20 is sent to the control means 40. In the map information acquired by the map information acquisition means 20, the route is represented by a node and a link connecting the nodes.

  The input means 30 is composed of, for example, an operation switch and a touch panel, and is used for inputting a point on the route such as a departure place, a waypoint, and a destination. The point data representing the point input by the input unit 30 is sent to the control unit 40. The control means 40 is composed of a microcomputer, for example, and controls the entire navigation system. Details of the control means 40 will be described later. The output means 50 is composed of, for example, a monitor display or the like, and displays the guide route as an image based on the drawing data sent from the control means 40.

  Next, details of the control means 40 will be described. As shown in FIG. 1, the control unit 40 includes a route search unit 41, a distance calculation unit 42, and an output control unit 43.

  The route search unit 41 searches for a route from the current position detected by the position detection unit 10 to the destination input from the input unit 30 based on the map information acquired by the map information acquisition unit 20. The route data representing the route searched by the route search means 41 is sent to the distance calculation means 42 and the output control means 43.

  The distance calculation means 42 calculates the distance from each point on the route indicated by the route data sent from the route search means 41 to the destination input from the input means 30. This distance calculation means 42 has a road distance calculation function and a straight line distance calculation function. The road distance calculation function extracts a link constituting the route indicated by the route data sent from the route search means 41 from the map information acquired from the map information acquisition means 20, and calculates the length of the extracted link. This is a function to calculate the road distance by summing up. The straight line distance calculation function extracts the coordinates of the point on the route indicated by the route data sent from the route search means 41 and the coordinates of the destination from the map information acquired from the map information acquisition means 20, and calculates both coordinates. This is a function for calculating a straight line distance by calculating a distance. The distance data representing the distance calculated by the distance calculating means 42 (the road distance data representing the road distance or the straight distance data representing the straight distance) is sent to the output control means 43.

  The output control unit 43 generates drawing data for drawing a route to be output to the output unit 50 based on the route data from the route search unit 41 and the distance data from the distance calculation unit 42. The drawing data generated by the output control means 43 is sent to the output means 50. As a result, the guide route is displayed on, for example, a monitor display of the output means 50.

  Next, the operation of the navigation system according to Embodiment 1 of the present invention will be described with reference to the flowchart shown in FIG. 2 and the screen display example shown in FIG. In the navigation system according to the first embodiment, the road distance is used as the distance from each point on the route to the destination.

  When the destination is input from the input unit 30, the route search unit 41 executes a route search from the current position detected by the position detection unit 10 to the destination. The route data obtained by this route search is sent to the distance calculation means 42. Based on the route data sent from the route search means 41, the distance calculation means 42 is a first point on the 1 km route from the destination and a second point on the 10 km route from the destination. Is calculated. Data representing the first point and the second point is sent to the output control means 43.

  The output control means 43 executes a route line display process described below. That is, as shown in the flowchart of FIG. 2, first, a route less than 1 km along the road from the destination, that is, a section from the destination to the first point is bolded (step ST10). Next, a route from 1 km to less than 10 km along the road from the destination, that is, a section from the first point to the second point is made a dotted line (step ST11). Next, a route from the destination to the route of 10 km or more, that is, a section from the second point to the departure point (the current position of the vehicle when inputting the destination) is made a thin solid line (step ST12).

  The output control unit 43 generates drawing data in which each section of the route is represented by different types of lines as described above, and sends the drawing data to the output unit 50. As a result, for example, as shown in FIG. 3, a route represented by a different type of line for each section is displayed as a guidance route on the monitor display of the output means 50. In FIG. 3, “S” indicates the search start point, “G” indicates the destination, and the vehicle mark represented by a triangle indicates the current position of the vehicle. The same applies to the display screen examples described below.

  A route change may occur for some reason while a vehicle equipped with a navigation system is moving. In this case, after the route search unit 41 performs route re-search, the above-described processing is re-executed and the route is redrawn.

  Next, the operation of the navigation system according to the modification of the first embodiment of the present invention will be described with reference to the flowchart shown in FIG. 4 and the screen display example shown in FIG. In the navigation system according to the modification of the first embodiment, a linear distance is used as the distance from each point on the route to the destination.

  When the destination is input from the input unit 30, the route search unit 41 executes a route search from the current position detected by the position detection unit 10 to the destination. The route data obtained by this route search is sent to the distance calculation means 42. Based on the route data sent from the route search means 41, the distance calculation means 42 is a first point on a 1 km route from the destination and a second point on a 10 km route from the destination. Is calculated. Data representing the first point and the second point is sent to the output control means 43.

  The output control means 43 executes a route line display process described below. That is, as shown in the flowchart of FIG. 4, first, a route having a linear distance from the destination of less than 1 km, that is, a section from the destination to the first point is made a bold line (step ST20). Next, a route with a linear distance of 1 km or more and less than 10 km from the destination, that is, a section from the first point to the second point is made a dotted line (step ST21). Next, a route from the destination to a straight distance of 10 km or more, that is, a section from the second point to the departure point (current position of the vehicle when inputting the destination) is made a thin solid line (step ST22).

  The output control unit 43 generates drawing data in which each section of the route is represented by different types of lines as described above, and sends the drawing data to the output unit 50. As a result, for example, as shown in FIG. 5, a route represented by a different type of line for each section is displayed as a guidance route on the monitor display of the output means 50 or the like.

  A route change may occur for some reason while a vehicle equipped with a navigation system is moving. In this case, after the route search unit 41 performs route re-search, the above-described processing is re-executed and the route is redrawn.

  In the first embodiment described above and its modification, the searched route is divided into three sections of less than 1 km, less than 1 km, less than 10 km, and more than 10 km. However, the number of divisions is not limited to three and is arbitrary. In addition, the distance between the sections is not limited to the distance described above, but is arbitrary.

  Further, in the above-described first embodiment and its modification, each section is configured to be displayed with different types of route lines. For example, a section whose distance to the destination is less than 1 km is blue, and 1 to 10 km. The route lines of each section may be displayed in different colors, such as green for the section 10 and yellow for the section 10 km or more. Furthermore, it can also be configured to display by changing the blinking cycle of the route line of each section.

  As described above, according to the navigation system according to the first embodiment of the present invention, a plurality of sections obtained by dividing the searched route according to the road distance to the destination are displayed for each section. Since the display is made with different types of route lines, visual recognition of the remaining distance to the destination is facilitated, and comfortable movement can be realized.

  Further, according to the navigation system according to the modification of the first embodiment of the present invention, the plurality of sections obtained by dividing the searched route according to the straight line distance to the destination are different for each section. Since it is configured to display with the kind of route lines, in addition to the same effect as the navigation system according to the first embodiment described above, there is an effect that the time for distance calculation can be shortened.

Embodiment 2. FIG.

  The distance calculation unit 42 calculates the distance from the current position detected by the position detection unit 10 to each point on the route indicated by the route data sent from the route search unit 41. This distance calculation means 42 has a road distance calculation function and a straight line distance calculation function, as in the first embodiment. The distance data representing the distance calculated by the distance calculating means 42 (the road distance data representing the road distance or the straight distance data representing the straight distance) is sent to the output control means 43.

  Next, the operation of the navigation system according to Embodiment 2 of the present invention will be described with reference to the flowchart shown in FIG. 6 and the screen display example shown in FIG. In the navigation system according to the second embodiment, the road distance is used as the distance from the current position of the vehicle to each point on the route.

  When the destination is input from the input unit 30, the route search unit 41 executes a route search from the current position detected by the position detection unit 10 to the destination. The route data obtained by this route search is sent to the distance calculation means 42. Based on the route data sent from the route search means 41, the distance calculation means 42 is a first point on the route 1km from the current position of the own vehicle, and 10km from the current position of the own vehicle. A second point on the route is calculated. Data representing the first point and the second point is sent to the output control means 43.

  The output control means 43 executes a route line display process described below. That is, as shown in the flowchart of FIG. 6, first, a route less than 1 km from the current position of the own vehicle, that is, a section from the current position of the own vehicle to the first point is made a thick line (step ST30). Next, a route from 1 km to less than 10 km from the current position of the vehicle, that is, a section from the first point to the second point is made a dotted line (step ST31). Next, a route of 10 km or more from the current position of the vehicle, that is, a section from the second point to the destination is made a thin solid line (step ST32).

  The output control unit 43 generates drawing data in which each section of the route is represented by different types of lines as described above, and sends the drawing data to the output unit 50. As a result, for example, as shown in FIG. 7, a route represented by a different type of line for each section is displayed as a guide route on the monitor display of the output means 50.

  The above processing is re-executed every time the navigation system moves a predetermined distance or every time a predetermined time elapses after the input of the destination is completed. This re-execution redraws the route. Note that the predetermined distance and the predetermined time may be fixedly determined in advance or may be arbitrarily set by the user.

  Next, the operation of the navigation system according to the modification of the second embodiment of the present invention will be described with reference to the flowchart shown in FIG. 8 and the screen display example shown in FIG. In the navigation system according to the modification of the second embodiment, a linear distance is used as the distance from the current position of the vehicle to each point on the route.

The route data obtained by this route search is sent to the distance calculation means 42. Based on the route data sent from the route search means 41, the distance calculation means 42 is a first point on the route with a linear distance of 1 km from the current position of the host vehicle, and a distance of 10 km from the current position of the own vehicle. A second point on the route is calculated. Data representing the first point and the second point is sent to the output control means 43.

  The output control means 43 executes a route line display process described below. That is, as shown in the flowchart of FIG. 8, first, a route having a linear distance of less than 1 km from the current position of the own vehicle, that is, a section from the current position of the own vehicle to the first point is bolded (step ST40). Next, a route with a linear distance of 1 km or more and less than 10 km from the current position of the vehicle, that is, a section from the first point to the second point is made a dotted line (step ST41). Next, a route having a straight distance of 10 km or more from the current position of the vehicle, that is, a section from the second point to the destination is made a thin solid line (step ST42).

  The output control unit 43 generates drawing data in which each section of the route is represented by different types of lines as described above, and sends the drawing data to the output unit 50. As a result, for example, as shown in FIG. 9, a route represented by a different type of line for each section is displayed as a guidance route on the monitor display of the output means 50 or the like.

  The above processing is re-executed every time the navigation system moves a predetermined distance or every time a predetermined time elapses after the input of the destination is completed. This re-execution redraws the route. The predetermined distance and the predetermined time can be fixedly determined in advance or can be arbitrarily set by the user.

  In the above-described second embodiment and its modification, the searched route is divided into three sections of less than 1 km, less than 1 km, less than 10 km, and more than 10 km. However, the number of divisions is not limited to three and is arbitrary. In addition, the distance between the sections is not limited to the distance described above, but is arbitrary.

  Further, in the above-described second embodiment and the modification thereof, the route line of each section is configured to be displayed differently. For example, a section whose distance from the current position of the own vehicle is less than 1 km is blue, The route line of each section can be displayed in different colors such that the section of 1 to 10 km is green and the section of 10 km or more is yellow. Furthermore, it can also be configured to display by changing the blinking cycle of the route line of each section.

  As described above, according to the navigation system of the second embodiment of the present invention, a plurality of sections obtained by dividing the searched route according to the road distance to the destination are divided for each section. In other words, it is configured to display with different types of route lines, so it is easy to visually recognize the remaining distance to the destination, and comfortable movement can be realized.

  Further, according to the navigation system according to the modification of the second embodiment of the present invention, the plurality of sections obtained by dividing the searched route according to the straight line distance to the destination are different for each section.

Is calculated. Data representing the first point and the second point is sent to the output control means 43.

  The output control means 43 performs a display process of the vehicle mark described below. That is, as shown in the flowchart of FIG. 10, first, it is checked whether the distance to the destination is less than 1 km along the road, that is, whether it is a section from the destination to the first point (step ST50). . Here, when it is determined that the distance to the destination is less than 1 km along the road, the color of the vehicle mark is set to blue (step ST51).

  If it is determined in step ST50 that the distance to the destination is not less than 1 km along the road, it is then checked whether the distance to the destination is not less than 1 km and less than 10 km along the road (step ST52). Here, when it is determined that the distance to the destination is 1 km or more and less than 10 km along the road, the color of the vehicle mark is changed to green (step ST53). If it is determined in step ST52 that the distance to the destination is not 1 km or more and less than 10 km along the road, it is recognized that the distance is 10 km or more, and the color of the vehicle mark is changed to yellow (step ST54).

  The output control means 43 generates drawing data in which the vehicle mark is expressed in a different color for each section as described above, and sends it to the output means 50. As a result, the route to which the vehicle mark whose color changes according to the distance to the destination is displayed as a guide route on the monitor display of the output means 50 or the like.

  The above processing is re-executed every time the navigation system moves a predetermined distance or every time a predetermined time elapses after the input of the destination is completed. By this re-execution, the route including the own vehicle mark is redrawn. Note that the predetermined distance and the predetermined time may be fixedly determined in advance or may be arbitrarily set by the user.

  In the third embodiment described above, the road distance is used as the distance from the current position of the vehicle to the destination. However, as in the navigation system according to the modification of the first embodiment, the target position is changed from the current position of the vehicle. A linear distance can also be used as the distance to the ground.

  In the third embodiment described above, the searched route is divided into three sections of less than 1 km, less than 1 km, less than 10 km, and more than 10 km. However, the number of divisions is not limited to three and is arbitrary. The distance is not limited to the distance described above, but is arbitrary.

In the navigation system according to the fourth embodiment, the road distance is used as the distance from each point on the route to the destination.

  When the destination is input from the input unit 30, the route search unit 41 executes a route search from the current position detected by the position detection unit 10 to the destination. The route data obtained by this route search is sent to the distance calculation means 42. The distance calculation means 42 calculates the road distance from the current position of the vehicle to the destination based on the route data sent from the route search means 41 and sends it to the output control means 43.

  As shown in the flowchart of FIG. 11, the output control means 43 divides the route represented by the route data sent from the route search means 41 into four equal parts according to the road distance, and changes the line type for each section. Drawing data is generated and sent to the output means 50, and a path with a different line type is drawn for each section (step ST60). As a result, for example, as shown in FIG. 12, a route represented by different types of lines for each of the four divided sections is displayed as a guide route on the monitor display of the output means 50 or the like. FIG. 12 shows an example in which the route is divided into four equal parts by the road distance and drawn with a thin dotted line, a thin solid line, a thick dotted line, and a thick solid line from the side closer to the current position of the vehicle.
