Description

  The present invention relates to route guidance in a navigation device.

  2. Description of the Related Art A navigation device for a moving body such as a vehicle is known that searches for a travel route to a destination designated by a user and performs route guidance along the route. In general, during route guidance, a guidance image showing a guidance route is displayed on a map near the current position. On the other hand, when the route guidance is completed, the guidance route is not displayed. However, in Patent Document 1, the direction line connecting the current position of the vehicle and the destination is displayed to assist the travel to the destination after the guidance is completed. A method is described.

  However, even if the direction line connecting the current position and the destination is displayed and the direction of the destination is known, the destination is not always displayed on the screen because of the scale of the map image. It's hard to say that direction lines are useful enough. Further, until the destination is sufficiently approached, the user often places more importance on the positional relationship between the current position and the next guide point rather than the direction of the destination.

[Route guidance unit]
FIG. 2 shows a functional configuration of the route guidance unit according to this embodiment. The route guidance unit 200 is actually realized by the components of the navigation device 100 shown in FIG. The route guidance unit 200 includes a destination setting unit 210, a guidance route determination unit 211, a route guidance unit 212, a departure detection unit 213, a reroute unit 214, an auto reroute unit 215, and a display control unit 216. Prepare. These are realized by the CPU 22 of the system controller 20 shown in FIG. 1 executing a prepared program.

  The destination setting unit 210 acquires information on a destination input by the user by operating the input device 60, and sets the destination information in the route guidance. The guide route determination unit 211 searches for and determines a guide route from the current position of the vehicle to the destination set by the destination setting unit 210. The current position of the vehicle is detected by the self-supporting positioning device 10 and the GPS receiver 18 and supplied to the system controller 20. The departure place of the guidance route is typically the current position of the vehicle. For example, when the user designates the departure place, the guidance route from the departure place to the destination is determined.

  The route guidance unit 212 provides route guidance to the user so that the vehicle travels according to the guidance route determined by the guidance route determination unit 211. Specifically, the route guidance unit 212 displays a map image including the current position of the vehicle and the guidance route on the display unit 40, and performs voice guidance through the voice output unit 50 as necessary. Among these, the control for displaying the map image on the display unit 40 is performed through a display control unit 216 described later. The present invention is characterized in a method of displaying a map image on the display unit 40 during route guidance, which will be described in detail later.

  The departure detection unit 213 detects that the vehicle has deviated from the guidance route. Specifically, the departure detection unit 213 compares the current position of the vehicle with the position coordinates of the roads that constitute the guide route, and the vehicle guides when the current position of the vehicle is more than a predetermined distance away from the guide route. Judge that it deviated from the route.

  The reroute unit 214 performs reroute processing according to a user instruction when the vehicle deviates from the guide route. “Reroute processing” refers to processing for resetting a guide route from the current position of the vehicle to the destination when the vehicle deviates from the guide route. In an example of route guidance processing to be described later, the reroute unit 214 forcibly executes a reroute when a predetermined time elapses after the vehicle deviates from the guidance route even if there is no user instruction. There is.

  The auto reroute unit 214 automatically executes reroute when the vehicle deviates from the guide route when the auto reroute function is set to ON. The user sets the auto reroute function to either on or off according to the prior setting. When the auto reroute function is set to ON, when the vehicle deviates from the guide route, the auto reroute unit 214 automatically executes the reroute process without making an inquiry to the user. On the other hand, when the auto reroute function is set to off, the reroute process is not executed even if the vehicle deviates from the guide route.

  Note that “reroute processing” refers to processing for resetting the guide route from the current position of the vehicle to the destination when the vehicle deviates from the guide route. It is automatically set by turning on the auto reroute function. The rerouting process executed in the above is particularly called “auto-rerouting process”. Then, the auto reroute process is executed by the auto reroute unit 215. Therefore, as described above, when the vehicle deviates from the guidance route, the reroute processing that is executed according to the user's instruction and the reroute processing that is forcibly executed when there is no user's instruction within a predetermined time, This is “reroute processing” executed by the reroute unit 214, and is distinguished from “auto reroute processing” executed by the auto reroute unit 215 when the auto reroute function is set to ON.

  The display control unit 216 basically performs control to display a map image and other menu images on the display unit 40. In the present embodiment, the display control unit 216 is characterized in that a “guidance point display image” is displayed on the display unit 40 during route guidance.

[Guidance point display image]
The guidance point display image will be described in detail below. The “guidance point display image” is an image including the current position of the vehicle, the next guidance point on the guidance route, and a guidance direction line connecting the current position of the vehicle and the next guidance point. In the following description, a normal display image during route guidance is referred to as a “normal guidance image” in order to distinguish it from the “guidance point display image” according to the present invention.

(First example)
First, a first example of the guidance point display image will be described. FIG. 3A is an example of a normal guidance image shown for comparison. As shown in the figure, in the normal guidance image 110, a guidance route 150 and a vehicle mark 151 indicating the current position of the vehicle are displayed on a map image around the current position of the vehicle. The guide route 150 is displayed separately from other roads depending on the display color, the thickness of the display line, and the like. In the present embodiment, the guide route 150 is indicated by a thick broken line for convenience of illustration.

  FIG. 3B shows a first example of the guidance point display image. In this first example, a two-screen display in which the display screen is divided into two parts is adopted, and a guide point display image is displayed on one of them. An image 115 on the left side in FIG. 3B shows only the periphery of the current position of the same image as the normal guide image 110 shown in FIG. On the other hand, the image on the right side is the guidance point display image 120a according to the first example, the guidance route 150, the own vehicle mark 151 indicating the current position of the vehicle, and the guidance point indicating the next guidance point on the guidance route. A mark 155 and a guide point direction line 152 that is a line connecting the vehicle mark 151 and the next guide point mark 155 are displayed on one screen. Thus, in order to display the guidance point display image 120a, it is necessary to change the scale of the map image as necessary. In the example of FIGS. 3A and 3B, the next guide point indicated by the guide point mark 155 is set in the vicinity of the track 156 as shown in the guide point display image 120a of FIG. The guide point is outside the display range of the normal guide image 110 shown in FIG. 3A, more specifically, on the right side of the right end of the normal guide image shown in FIG. That is, the scale of the guidance point display image 120a shown in FIG. 3B is adjusted so that it is displayed in a wider area than the normal guidance image 110 shown in FIG.

  Thus, in the guidance point display image, the current position of the vehicle, the next guidance point on the guidance route, and the guidance point direction line connecting the current position of the vehicle and the next guidance point are displayed. Accordingly, the user can know at a glance the positional relationship between the current position and the next guide point on the guide route, the direction of the next guide point, and the like by looking at the guide point display image. For this reason, the guidance point display image is particularly effective when displayed when the vehicle deviates from the guidance route, as will be described later.

(Second example)
Next, a second example of the guidance point display image will be described. FIG. 4A is an example of a normal guidance image shown for comparison, and is the same as FIG. FIG. 4B shows a second example of the guidance point display image. In this example, the guide point display image 120b is not a normal map image but an image of a simplified map (also referred to as “deformation map” or the like) that shows a simplified position and direction. Also in the guide point map image 120b according to the second example, the own vehicle mark 151 indicating the current position of the vehicle, the guide point mark 155 indicating the next guide point, and the guide point direction connecting the current position and the next guide point. Line 152 is shown on one screen. Therefore, the user can know at a glance the positional relationship between the current position and the next guide point on the guide route, the direction of the next guide point, and the like by looking at the guide point display image.

(Third example)
Next, a third example of the guidance point display image will be described. FIG. 5A is an example of a normal guidance image shown for comparison, and is the same as FIG. FIG. 5B shows a third example of the guide point display image. In this example, the guide point display image 120c has a one-screen configuration, and includes a vehicle mark 151 indicating the current position of the vehicle, a guide point mark 155 indicating the next guide point, and the current position and the next guide point. The scale is adjusted so that the guide point direction line 152 to be connected can be displayed on one screen. That is, as compared with the normal guidance image 110 in FIG. 5A, the guidance point display image 120c shown in FIG. 5B has a smaller scale (that is, wide area display). The guidance route 150 is also displayed in the guidance point display image 120c.

(Fourth example)
Next, a fourth example of the guidance point display image will be described. FIG. 6A is an example of a normal guidance image shown for comparison, and is the same as FIG. FIG. 6B shows a third example of the guide point display image. In this example, the guide point display image 120d has a one-screen configuration, and includes a vehicle mark 151 indicating the current position of the vehicle, a guide point mark 155 indicating the next guide point, and the current position and the next guide point. The scale is adjusted so that the guide point direction line 152 to be connected can be displayed on one screen. The guidance route 150 is also displayed in the guidance point display image 120d.

  Compared to the third example, in the fourth example, the display position of the vehicle mark 151 is adjusted in the display screen. Usually, the own vehicle mark 151 is often displayed near the center of the display screen. In the fourth example, the own vehicle mark 151 is shifted to the position of the end of the screen without changing the scale so much. The current position, the next guidance point, and the guidance point direction line can be displayed on one screen. Specifically, the guidance point display image 120d shown in FIG. 6B has a smaller scale (that is, wide area display) than the normal guidance image shown in FIG. As the position is moved, the scale is larger (that is, the detailed display) than the guidance point display 120c shown in FIG.

[Route guidance processing]
Next, route guidance processing according to the embodiment will be described. The route guidance process according to the following embodiment displays the above guidance point display image during route guidance.

(First embodiment)
In the first example of the route guidance process, the display control unit 216 displays a guidance point display image according to any of the first to fourth examples described above during route guidance. In this case, it is preferable that the user can select and set which of the first to fourth guidance point display images is displayed in advance on the menu screen or the like. Further, the guidance point display image shows a positional relationship between the current position of the vehicle and the next guidance point, and is updated every time the vehicle passes through the guidance point. That is, when the vehicle passes through the guide point, a new guide point display image including the current position of the vehicle, a new next guide point, and a guide point direction line connecting them is generated and displayed.

  FIG. 7 shows a flowchart of route guidance processing according to the first embodiment. This process is realized by the system controller executing a route guidance program prepared in advance and functioning as each component shown in FIG.

  First, when the route guidance unit 212 starts route guidance, the display control unit 216 displays a guidance point display image for the next guidance point (step S101). Here, the guide point display image can be any of the examples shown in FIGS. 3B, 4B, 5B, and 6B, and preferably as described above. Assume that you have selected.

  Next, the route guidance unit 212 determines whether the vehicle has reached the destination based on the current position of the vehicle (step S102). When the vehicle has reached the destination (step S102; Yes), the route guidance unit 212 ends the route guidance.

  On the other hand, when the vehicle has not reached the destination (step S102; No), the route guidance unit 212 determines whether or not the vehicle has passed the guidance point (step S103). When the vehicle has passed the guidance point (step S103; Yes), the display control unit 216 creates and displays a guidance point display image for the next guidance point (step S104).

  Thus, each time the vehicle passes through the guidance point, a guidance point display image for the next guidance point is created and displayed. Thereby, the user can always continue traveling while recognizing the positional relationship between the current position and the next guide point and the direction of the next guide point.

  In the above example, the guide point display image is displayed from the beginning of route guidance. Instead, a normal guidance image may be displayed until passing the guidance point, and after passing through the guidance point, a guidance point display image for the next guidance point may be displayed for a predetermined time or a predetermined distance.

(Second embodiment)
In the second example of the route guidance process, when the vehicle is traveling along the guidance route during route guidance, a normal guidance image is displayed. On the other hand, when the vehicle deviates from the guidance route, a two-screen guidance point display image, that is, the guidance point display image according to the first or second example described above is displayed. This is because the guide point display image of the present invention shows the positional relationship between the current position and the next guide point in an easy-to-understand manner, so that the vehicle deviates from the guide route and the user returns to the guide route. This is especially useful when driving.

  FIG. 8 shows a flowchart of route guidance processing according to the second embodiment. First, when the route guidance unit 212 starts route guidance, the display control unit 216 displays a normal guidance image illustrated in FIG. 3A (step S201). Next, the route guidance unit 212 determines whether the vehicle has reached the destination based on the current position of the vehicle (step S202). When the vehicle has reached the destination (step S202; Yes), the route guidance unit 212 ends the route guidance.

  When the vehicle has not reached the destination (step S202; No), the departure detection unit 213 determines whether the vehicle has deviated from the guidance route (step S203). When the vehicle does not deviate from the guidance route (step S203; No), the display control unit 216 returns to step S201 and continues displaying the normal guidance image. On the other hand, when the vehicle deviates from the guidance route (step S203; Yes), the display control unit 216 generates and displays a two-screen guidance point display image according to the first or second example (step S204). As a result, when the vehicle deviates from the guidance route, the user returns to the guidance route while looking at both the normal guidance image and the guidance point guidance image as shown in FIG. 3B or 4B. So that you can travel.

  In the above example, when the vehicle deviates from the guidance route, the display control unit 216 displays the two-screen guidance point display image shown in FIG. 3 (B) or FIG. 4 (B). Instead, a guidance point display image shown in FIG. 5B or FIG. 6B may be displayed.

  As a modification of the second embodiment, the above process may be executed only when the auto-reroute function is set to off. This is because when the auto reroute function is set to ON, if the vehicle deviates from the guide route, the auto reroute process is executed immediately and a new guide route is set. Because there is no.

  As another modification, when the function of displaying the guidance point display image when the vehicle deviates from the guidance route is enabled by the setting of the menu or the like, the auto reroute function is automatically set to off. It is good as well. This is because, as described above, the function of displaying a guidance point display image when the vehicle deviates from the guidance route and the auto reroute function are of a property that can be selectively used.

(Third embodiment)
In the third example of the route guidance process, when the vehicle is traveling along the guidance route during route guidance, a normal guidance image is displayed. On the other hand, when the vehicle deviates from the guidance route, a two-screen guidance point display image, that is, the guidance point display image according to the first or second example described above is displayed. Along with this, the route guidance unit 212 inquires of the user whether or not to reroute, and when the user instructs the reroute, the reroute is executed accordingly. Furthermore, if the user does not respond to the inquiry for a predetermined time or longer, the reroute is automatically executed.

  FIG. 9 shows a flowchart of route guidance processing according to the third embodiment. First, when the route guidance unit 212 starts route guidance, the display control unit 216 displays a normal guidance image illustrated in FIG. 3A (step S301). Next, the route guidance unit 212 determines whether the vehicle has reached the destination based on the current position of the vehicle (step S302). When the vehicle has reached the destination (step S302; Yes), the route guidance unit 212 ends the route guidance.

  When the vehicle has not reached the destination (step S302; No), the departure detection unit 213 determines whether the vehicle has deviated from the guidance route (step S303). When the vehicle has not deviated from the guidance route (step S303; No), the display control unit 216 returns to step S301 and continues displaying the normal guidance image. On the other hand, when the vehicle deviates from the guidance route (step S303; Yes), the display control unit 216 generates and displays a two-screen guidance point display image according to the first or second example (step S304). As a result, when the vehicle deviates from the guidance route, the user returns to the guidance route while looking at both the normal guidance image and the guidance point guidance image as shown in FIG. 3B or 4B. So that you can travel.

  In addition, the route guidance unit 212 starts measuring the elapsed time after the vehicle deviates from the guidance route (step S305), and determines whether or not to reroute the user using a voice message or the like. An inquiry is made (step S306).

  When the user gives a reroute instruction (step S307; Yes), the reroute unit 214 executes the reroute. That is, a new guide route from the current position to the destination is calculated (step S309), and the result is displayed on the display unit 40 (step S310). Thereby, the user can travel to the destination according to the new guidance route.

  On the other hand, when there is no reroute instruction by the user (step S307; No), the route guidance unit 212 determines whether or not a predetermined time has elapsed since the vehicle deviated from the guidance route (step S308). If the predetermined time has not elapsed (step S308; No), the route guide unit 212 continues to wait for a reroute instruction from the user. On the other hand, when the predetermined time has elapsed (step S308; Yes), the route guide unit 212 forcibly executes the reroute process. That is, the route guidance unit 212 calculates a new guidance route even if there is no reroute instruction from the user (step S309), and displays the result (step S310). As a result, the route guidance is continued based on the new guidance route obtained by the reroute processing.

  Thus, in the third embodiment, when the vehicle deviates from the guidance route, the normal guidance image is first switched to the guidance point display image. Therefore, even when the user deviates from the guidance route, the user can know the positional relationship between the current position and the next guidance point and the direction of the next guidance point by looking at the guidance point display image. It becomes easy to travel back.

  Further, when the vehicle deviates from the guidance route, an inquiry about whether or not to reroute is made to the user, so that the user can instruct reroute. Thereby, even if the vehicle deviates from the guidance route, a new guidance route from the current position to the destination is set, so that the user can use the new guidance route to go to the destination. .

  Further, if the user does not give a reroute instruction for a predetermined time or more after the vehicle deviates from the guidance route, the reroute is automatically executed. If this predetermined time is set to an appropriate time, the user does not want to reroute and tries to return to the guidance route himself, but it does not go well and it takes time to return to the original guidance route. Reroute is automatically performed when it is necessary. Therefore, the user can use a new guidance route.

  In the above example, when the vehicle deviates from the guidance route, the display control unit 216 displays the two-screen guidance point display image shown in FIG. 3 (B) or FIG. 4 (B). Instead, a guidance point display image shown in FIG. 5B or FIG. 6B may be displayed.

(Fourth embodiment)
In the fourth embodiment of the route guidance process, when the vehicle is traveling along the guidance route during route guidance, a normal guidance image is displayed. On the other hand, when the vehicle deviates from the guidance route, a two-screen guidance point display image, that is, the guidance point display image according to the first or second example described above is displayed. The process up to this point is the same as in the third embodiment. In addition, in the fourth embodiment, the reroute unit 214 starts reroute calculation as soon as the vehicle deviates from the guide route. The route guidance unit 212 inquires of the user whether or not to reroute, and when the user instructs the reroute, the reroute is executed accordingly. Further, if the user does not respond to the inquiry for a predetermined time or more, the route guide unit 212 determines the distance from the current position to the next guide point of the original guide route and the next guide in the new guide route obtained by the reroute. The distance to the point is compared, and when the next guide point of the new guide route is closer, the reroute result is automatically reflected.

  FIG. 10 shows a flowchart of route guidance processing according to the fourth embodiment. First, when the route guidance unit 212 starts route guidance, the display control unit 216 displays a normal guidance image illustrated in FIG. 3A (step S401). Next, the route guidance unit 212 determines whether the vehicle has reached the destination based on the current position of the vehicle (step S402). When the vehicle has reached the destination (step S402; Yes), the route guidance unit 212 ends the route guidance.

  When the vehicle has not reached the destination (step S402; No), the departure detection unit 213 determines whether the vehicle has deviated from the guidance route (step S403). When the vehicle does not deviate from the guidance route (step S403; No), the display control unit 216 returns to step S401 and continues displaying the normal guidance image. On the other hand, when the vehicle deviates from the guidance route (step S403; Yes), the display control unit 216 generates and displays a two-screen guidance point display image according to the first or second example (step S404). As a result, when the vehicle deviates from the guidance route, the user returns to the guidance route while looking at both the normal guidance image and the guidance point guidance image as shown in FIG. 3B or 4B. So that you can travel.

  In addition, the route guide unit 212 starts measuring the elapsed time after the vehicle deviates from the guide route (step S405), and the reroute unit 214 starts reroute calculation (step S406). Subsequently, the route guidance unit 212 inquires of the user whether or not to perform reroute using a voice message or the like (step S407).

  When the user gives a reroute instruction (step S408; Yes), the reroute unit 214 reflects the reroute result obtained by the reroute calculation already performed (step S411). That is, a new guide route from the current position to the destination is displayed on the display unit 40. Thereby, the user can travel to the destination according to the new guidance route.

  On the other hand, when there is no reroute instruction by the user (step S408; No), the route guidance unit 212 determines whether or not a predetermined time has elapsed since the vehicle deviated from the guidance route (step S409). If the predetermined time has not elapsed (step S409; No), the route guidance unit 212 continues to wait for a reroute instruction from the user. On the other hand, when the predetermined time has elapsed (step S409; Yes), the route guide unit 212 proceeds from the current position to the next guide point in the original guide route and the next in the new guide route obtained by the reroute. Are compared (step S410). If the next guidance point in the new guidance route after the reroute is closer (step S410; Yes), the reroute result obtained by the reroute calculation already performed is reflected (step S411). On the other hand, when the next guidance point in the original guidance route is closer (step S410; No), the two-screen guidance point display image continues.

  Thus, in the fourth embodiment, when the vehicle deviates from the guidance route, the normal guidance image is first switched to the guidance point display image. Therefore, even when the user deviates from the guidance route, the user can know the positional relationship between the current position and the next guidance point and the direction of the next guidance point by looking at the guidance point display image. It becomes easy to travel back.

  Further, when the vehicle deviates from the guidance route, an inquiry about whether or not to reroute is made to the user, so that the user can instruct reroute. As a result, a new guide route from the current position that deviates from the original guide point to the destination is set, so that the user can use the new guide route to go to the destination.

  Furthermore, even if the vehicle deviates from the guidance route, the guidance point display image continues to be displayed when the user is not instructing a reroute and intends to return to the guidance route. However, when the vehicle deviates from the guidance route, the reroute calculation is started behind the scenes, although it is not displayed on the display unit 40. And if the user does not give a reroute instruction within a predetermined time after the vehicle deviates from the guidance route, the next guidance point in the new guidance route obtained by the reroute will be the original one as seen from the current position. Only when it is closer than the next guide point in the guide route, the reroute result is forcibly reflected. Therefore, even if a certain amount of time has passed since the vehicle deviated from the guidance route, it is impossible to return to the original guidance route, and the current position is a new guidance obtained by the reroute being executed behind the scenes. If it is close to the next guide point on the route, it is forcibly reflected. As a result, the user can be smoothly guided to the destination.

  In the above example, when the vehicle deviates from the guidance route, the display control unit 216 displays the two-screen guidance point display image shown in FIG. 3 (B) or FIG. 4 (B). Instead, a guidance point display image shown in FIG. 5B or FIG. 6B may be displayed.
