  The present invention relates to a route guidance device.

2. Description of the Related Art Conventionally, a route guidance device that searches for a guidance route based on a route image when a user has a route image in advance is known as a route guidance device (see, for example, Patent Document 1). In this apparatus, a user traces a map displayed on a touch panel or the like with a finger, and a route image is input to search for a guidance route.
JP 2001-108465 A

  Such an apparatus has a configuration in which a route is specified after setting a destination. For example, because there is a lot of traffic in the opposite lane near the parking lot at the destination, even if you want to enter the destination and the route to some extent, such as when you want to enter the vehicle by turning left instead of right, route after setting the destination The operation of specifying is required.

  Accordingly, the present invention has been made to solve such a technical problem, and an object thereof is to provide a route guidance device in which an operation procedure is simplified.

  In other words, the route guidance device according to the present invention follows a designation start information input unit for inputting an arbitrary designated start point as a designated start point on the map displayed on the screen, and follows the map from the designated start point. A specified route information input unit that inputs a route connecting a specified start point and an arbitrary point to be specified as a specified route, and an arbitrary point that has been specified is input as a specified end point. A designation end information input unit and a guidance route setting unit that sets a guidance route based on the designated route are provided.

  With such a configuration, the designated start point, the designated end point, and the route connecting the designated start point and the designated end point can be set by a series of operations of the user. For example, touch the screen with your finger to determine the designated start point, trace the route from the designated start point to the designated end point without releasing your finger from the screen, and release the finger from the screen at the designated end point. Can be determined. Thereby, an operation procedure can be simplified.

  Here, the designated start point is preferably a guidance start point, and the designated end point is preferably a guidance end point. In this case, it is possible to reduce the input work load of the designated route for the user who imagines the route from the current location or a specific point to the destination.

  Alternatively, the designated start point may be a guidance end point, and the designated end point may be a guidance start point. In this case, it is possible to reduce the input work load of the designated route for a user who imagines a route starting from the destination.

  In the route guidance device, the guidance route setting unit includes a designated length calculation unit that calculates the length of the designated route on the screen, and a threshold setting unit that sets a threshold according to the scale of the map displayed on the screen. And comparing means for comparing the length of the designated route on the screen with a threshold, and setting the guide route when the length of the designated route on the screen is equal to or greater than the threshold.

  With such a configuration, even if the scale of the displayed map changes, by setting a threshold according to the map scale, whether or not the length of the designated route on the screen is greater than or equal to a predetermined length Can be judged. Thereby, since it can be determined whether or not the designated route is designated by an erroneous operation, it is possible to avoid setting the guidance route based on information not intended by the user. For example, when the user wants to set only the destination, it is possible to avoid setting the guidance route even in the case of an operation for unintentionally specifying the destination and the guidance route due to camera shake or the like. it can.

  In the route guidance device, it is preferable that the guidance route setting unit enlarges and displays the map of the specific point when inputting the designated route. With such a configuration, when the scale of the map is small, a point requiring guidance can be enlarged and displayed, so that the operability of the screen is improved and the occurrence of erroneous operations can be reduced.

  ADVANTAGE OF THE INVENTION According to this invention, in the apparatus which guides a route, the operation procedure of route setting can be simplified.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the description of the drawings, the same elements are denoted by the same reference numerals, and redundant description is omitted.

  FIG. 1 is a schematic configuration diagram of a navigation system 2 including a route guidance ECU (route guidance device) 1 according to the present embodiment. Here, the ECU (Electronic Control Unit) is a computer of an automobile device that is electronically controlled, and includes a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), an input / output interface, and the like. Configured.

  A route guidance ECU 1 shown in FIG. 1 is a device that guides a route when a user goes to a destination, and is suitably used in, for example, a car navigation system. Such a vehicle navigation system includes, for example, a display 3, a map DB 4, and a GPS receiver 5 in addition to the route guidance ECU 1, as in the navigation system 2 shown in FIG. Here, the GPS (Global Positioning System) is a measurement system using a satellite and is preferably used for grasping the current position of the host vehicle.

  The route guidance ECU 1 is connected to the display 3, the map DB 4 and the GPS receiver 5. For example, the route guidance ECU 1 obtains destination information and current location information from the map DB 4 and the GPS receiver 5, and sets the route to the destination. In addition, a function for outputting the set route to the display 3 is provided.

  The display 3 is a device that provides information to the user through vision, and includes a display control unit 33 and a panel (screen) 32. The display control unit 33 has a function of displaying an image based on an input signal, and controls an image displayed on the panel 32. The panel 32 is preferably composed of a so-called touch panel that can directly input information from the screen. The touch panel has an image display function and an input function that senses an input when the user touches the displayed screen. For example, the user presses or traces the display on the screen with a finger. This is a panel that receives an input and outputs a signal based on the input panel position. Thus, when the panel 32 is configured by a touch panel, the display 3 preferably includes the operation information output unit 31. The operation information output unit 31 has a function of outputting information input to the panel 32 to the route guidance ECU 1.

  The map DB 4 provided in the navigation system 2 is a database in which map information is stored, and is connected to the route guidance ECU 1. The GPS receiver 5 is an information terminal of the satellite positioning system, and is used to acquire the current position, and is connected to the route guidance ECU 1.

  The navigation system 2 configured as described above sets the route to the destination based on the destination information input to the display 3 by the user, displays the set route on the display 3, and guides the user. Provide driving assistance. When no route is specified by the user as a route setting to the destination, a candidate route is searched for and displayed. As this candidate route, for example, a route having a minimum required time is selected from among a plurality of candidate routes. Moreover, you may provide the function which displays a some candidate path | route and makes a user select.

  Here, the route guidance ECU 1 according to the present embodiment includes a designation start information input unit 11, a designation end information input unit 12, a designation route information input unit 13, and a guidance route setting unit 14. .

  The designation start information input unit 11, the designation end information input unit 12, and the designated route information input unit 13 are input units for inputting information operated by the user to the route guidance ECU 1. It has a function to input information. For example, the designation start information input unit 11 inputs a signal of a part (designation start point) where the user touches the panel 32 from the operation information output unit 31. The designation end information input unit 12 inputs a signal of a location (designation end point) where the user has lifted his / her finger from the panel 32 from the operation information output unit 31. The designated route information input unit 13 specifies that the user touches the panel 32 and follows the route on the map displayed on the panel 32 without releasing the finger from the panel 32, and releases the finger from the panel 32. The operation information output unit 31 inputs the route up to (the specified route).

  The guide route setting unit 14 has a function of setting a guide route, a guide start point, and a guide end point, and includes a guide route setting processing unit 18. The guide route setting processing unit 18 has a function of setting a designated route connecting the designated start point obtained from the designated start information input unit 11 and the designated end point as a guide route. At this time, the designated start point may be the guidance start point, the designated end point may be the guidance end point, the designated start point may be the guidance end point, and the designated end point may be the guidance start point. The guidance start and guidance end settings are realized, for example, by a configuration in which a user is switched by a switch or the like provided in the route guidance ECU 1.

  The guide route setting unit 14 preferably includes a threshold setting unit (threshold setting unit) 15, a designated length calculation unit (designated length calculation unit) 16, an erroneous operation determination unit (comparison unit) 17, and an enlarged display setting unit 19. Configured.

  The threshold value setting unit 15 has a function of setting a threshold value for determining whether or not information input by the user is input by an erroneous operation. For example, the scale information of the map information displayed on the panel 32 is input from the display control unit 33 provided in the display 3, and the threshold value for determining whether or not the operation is erroneous is set based on the input scale information. The threshold setting unit 15 has a function of outputting the set threshold to the erroneous operation determination unit 17.

  The designated length calculation unit 16 has a function of calculating the length on the screen of the designated route input by the user. For example, it has a function of inputting screen operation information from the designated route information input unit 13 and calculating the length of the designated route on the screen. The designated length calculation unit 16 has a function of outputting the calculated length of the designated route on the screen to the erroneous operation determination unit 17.

  The erroneous operation determination unit 17 has a function of determining whether information input by the user is input by an erroneous operation. For example, the threshold value is input from the threshold value setting unit 15, the length of the designated route on the screen is input from the designated length calculation unit 16, and the input threshold value is compared with the length of the designated route on the screen. Further, the erroneous operation determination unit 17 has a function of outputting the determined result to the guide route setting unit 18.

  The enlarged display setting unit 19 has a function of enlarging a specific point in order to improve screen operability. For example, a guidance route set from the guidance route setting unit 18 is input, and a point that is estimated to be enlarged, such as the current location or the vicinity of the destination, is enlarged in the guidance route. In addition, a function of outputting an enlarged display command to the display control unit 33 of the display 3 is provided.

  Next, the operation of the route guidance ECU 1 according to this embodiment will be described.

  FIG. 2 is a flowchart showing the operation of the route guidance ECU 1 according to this embodiment. FIG. 2 shows that when the route guidance ECU 1 inputs a start signal, for example, when a route setting start button and a route setting end button are provided on the screen and the user selects the route setting start button, the end signal is input. In this case, for example, it is repeatedly executed until a route setting end button is selected.

  As shown in FIG. 2, the route guidance ECU 1 starts from the threshold value setting process of S10. The process of S10 is a process of setting the threshold value n in order to determine whether the information input to the panel 32 by the user is input by an erroneous operation, which is executed by the threshold setting unit 15. The threshold setting unit 15 sets the threshold n according to the scale of the map displayed on the panel 32. For example, the physical length on the panel 32 corresponding to a distance of 200 m or more on the map displayed on the panel 32 is set as the threshold value n. For example, if the map scale is 1 / 5,000, 200m on the map is 0.8cm in physical length on the panel 32, and if the map scale is 1 / 10,000, 200 m is 2 cm in physical length on the panel 32. Therefore, when the scale of the map displayed on the panel 32 is 1 / 25,000, the threshold value n is set to 0.8, and the scale of the map displayed on the panel 32 is 1 / 10,000. In this case, the threshold value n is set to 2. When the threshold value setting process in S10 ends, the process proceeds to an operation information input process (S12).

  The process of S12 is a process which is executed by the designation start information input unit 11, the designation end information input unit 12, and the designated route information input unit 13 and inputs information inputted to the panel 32 by the user to the route guidance ECU 1. The designation start information input unit 11 inputs, for example, a designation start point where the user has touched the panel 32 from the operation information output unit 31. The designation end information input unit 12 inputs, for example, a designation end point where the user has lifted his / her finger from the panel 32 from the operation information output unit 31. In addition, the designated route information input unit 13 designates the user to touch the panel 32 and follow the route on the map displayed on the panel 32 without releasing the finger from the panel 32, and the finger is placed on the panel 32. A designated route from the operation information output unit 31 is input until it is released. In the following operation of the route guidance ECU 1, an example will be described in which a designated start point is set as a guidance end point, for example, a destination, and a designated end point is set as a guidance start point in consideration of easy understanding. When the process of S12 ends, the process proceeds to a specified length calculation process (S14).

  The process of S14 is a process executed by the designated length calculation unit 16 to calculate the length of the designated route input in S12 on the screen. For example, the length of the designated route on the screen is calculated using a signal corresponding to the designated route traced by the user with a finger. When the process of S14 ends, the process proceeds to an erroneous operation determination process (S16).

  The process of S16 is a process that is executed by the erroneous operation determination unit 17 and determines whether or not the information input to the panel 32 by the user is input by an erroneous operation. For example, the erroneous operation determination unit 17 determines the comparison by comparing the threshold value n calculated in S10 with the length of the designated route calculated in S14. If the length of the designated route on the screen is greater than or equal to the threshold value n in the process of S16, the process proceeds to the destination, guidance start point and guidance route setting process (S18).

  The process of S18 is executed by the guide route setting processing unit 18, and is a process for setting a destination, a guide start point, and a guide route. A destination is determined based on the designated start point input in S12 and the map information in the map DB4. Next, a guide route is set based on the designated route input in S12 and the map information in the map DB 4. At this time, when the route guidance ECU 1 has a function of displaying a plurality of candidate guidance routes, the search for candidate guidance routes is started immediately after the destination is set. In this way, the candidate route can be displayed earlier by searching for a guide route as a candidate while the user inputs the route. Next, a guidance end point is set based on the designated end point input in S12 and the map information in the map DB 4. When the process of S18 ends, the process proceeds to an enlarged display determination process (S22).

  The process of S22 is a process that is executed by the enlarged display setting unit 19 and determines whether or not it is necessary to set a more detailed route among the guide routes set in S18. For example, a point where the user is expected to set a route in more detail is stored as information in advance, and it is determined whether or not the route specified by the user includes a point that matches the information. Specific examples of such a point include a current point, a destination, a point where traffic conditions change, and a point where the road shape affects driving. The points where the traffic conditions change are, for example, points where traffic congestion frequently occurs, points where parking on the road is frequent, points where there are many intersections where there is no signal, and the like. The points where the road shape affects driving are, for example, a point where the road width is narrow, a sharp curve point, a steep slope point, and the like. In addition, what is necessary is just to judge a traffic condition based on VICS information, for example. Here, VICS (Vehicle Information and Communication System) is an information communication system that provides road traffic information in real time. In the process of S22, when it is necessary to set a more detailed route, the process proceeds to an enlarged display process (S24).

  The process of S24 is executed by the enlarged display setting unit 19, and performs an enlarged display of a point that requires the enlargement process. When the process of S24 ends, the control process shown in FIG. 2 ends.

  In the process of S16, when the length of the designated route on the screen is less than the threshold value n, it is determined that the route designation is an erroneous operation. That is, it is determined that the user's screen input is not a route designation and a destination designation, but a destination designation only. In this case, the process proceeds to the destination setting process (S20).

  The process of S20 is a process that is executed by the guide route setting processing unit 18 and sets a destination. The destination is determined based on the screen operation information input in S12, for example, the designated start point. When the process of S20 ends, the control process shown in FIG. 2 ends.

  If it is determined in step S22 that it is not necessary to set a more detailed route, the control process shown in FIG. 2 ends.

  This is the end of the control process of FIG. For ease of understanding, the designated start point is described as the guidance end point, and the designated end point is described as the guidance start point. However, when the designated start point is defined as the guidance start point and the designated end point is defined as the guidance end point, In the processes of S18 and S20, the designated start point may be read as the designated end point, and the designated end point may be read as the designated start point.

  Next, the effect of the route guidance ECU 1 according to the present embodiment will be described. As a specific example for explaining the effect, a route designation procedure to the destination will be explained. 3 and 4 are route designation procedures when the route guidance ECU 1 according to the present embodiment is used, and FIG. 9 is a route designation procedure when the conventional route guidance device is used. The panel 32 employs a touch panel, and description will be made assuming that information can be input by operating with a finger.

  In the conventional route designation procedure, as shown in FIG. 9, the destination G is designated by touching the screen on which the destination G is displayed as the procedure 1 (arrow Y0), and then the current location S as the procedure 2. Is touched with a finger (arrow Y1), the route is traced from the current location S to the destination G with a finger (arrow Y2), and the finger is released at the destination G (arrow Y3) to designate the designated route L.

  In contrast, in the route designation procedure of the route guidance ECU 1 according to the present embodiment, as shown in FIG. 3, the destination G is designated by touching the screen on which the destination G is displayed (arrow Y1 ′). ) Trace the route from the destination G to the current location S without releasing your finger from the screen (arrow Y2 ′), and specify the guidance end point by releasing your finger at the current location S, for example, the current location S (arrow) A designated route L is designated together with Y3 ′).

  In addition, as shown in FIG. 4, the guidance start point, for example, the current location S is specified by touching the screen with a finger (arrow Y1 ″), and the route from the current location S to the destination G without releasing the finger from the screen. Is traced with a finger (arrow Y2 ″), the guidance end point is designated by releasing the finger at the guidance end point, for example, the destination G (arrow Y3 ″), and the designated route L is designated.

  As described above, according to the route guidance ECU 1 according to the present embodiment, the destination G, the guidance end point, and the route L connecting the destination G and the guidance end point are set by a series of operations of the user. Can do.

  Further, according to the route guidance ECU 1 according to the present embodiment, even if the scale of the displayed map is changed, the length of the designated route L on the screen is set by setting a threshold according to the scale of the map. It can be determined whether or not is longer than a predetermined length. This makes it possible to determine whether or not the designated route L is designated by an erroneous operation, so that it is possible to avoid setting a guidance route based on information not intended by the user. For example, when the user wants to set only the destination G, even when the destination G and the route L are specified unintentionally due to camera shake or the like, it is possible to avoid setting the guidance route.

  Further, according to the route guidance ECU 1, since the point where the user starts specifying is the destination G and the point where the user ends is the guidance end point, for example, the current location S, the route starting from the destination G is imaged. It is possible to reduce the input work load of the designated route L for the user who is doing this. In addition, by specifying the destination G first in this way, it becomes possible to immediately search for a candidate route from the current location S to the destination G. This makes it possible to speed up the display of candidate routes when a function for displaying candidate routes other than the route designated by the user is used.

  Alternatively, the point where the user starts designating may be the guidance start point, and the point where the designation ends may be the destination G. In this case, the route from the current location S or a specific point to the destination G It is possible to reduce the input work load of the designated route for the user who imagines. In addition, by specifying the guidance starting point first in this way, it becomes possible to immediately search for candidate routes from the current location S to the guidance starting point. This makes it possible to speed up the display of candidate routes when using a function that displays candidate routes that always pass the route specified by the user.

  Further, in the route guidance ECU 1, when the scale of the map is small, a point where guidance is required can be enlarged and displayed, so that the operability of the screen is improved and the occurrence of an erroneous operation can be reduced. Further, by using the enlargement function, for example, it is possible to avoid the fact that the scale of the map becomes small when displaying the entire designated route, making it difficult to make detailed settings from the screen.

  In addition, embodiment mentioned above shows an example of the route guidance apparatus which concerns on this invention. The route guidance device according to the present invention is not limited to this, and the route guidance device according to the embodiment is modified so as not to change the gist described in each claim, or applied to other devices. It may be a thing.

  For example, in the embodiment, it is preferable that the panel 32 adopts a touch panel, and an example in which a user designates a route with a finger has been shown. However, the information input unit is not a touch panel, and information is input with a mouse or the like. Even so, the same effect as the embodiment can be obtained. In this case, the user designates the designated start point by placing the cursor and pressing the specific button, moves the cursor while pressing the specific button, and inputs a route connecting the designated start point and the designated end point, The designated end point can be specified by moving the cursor and releasing the specific button.

  In the embodiment, the threshold value n serving as a criterion for erroneous operation is determined according to the scale of the map. However, it may be determined whether or not the route is specified with the threshold value set to a constant value. In this case, for example, the configuration may be such that routing is performed only when the length operated as a physical operation amount is 1 cm or more.

  Further, in the embodiment, an example has been shown in which an entire guide route is set by a single route designation operation, and then enlarged display is performed in order to make detailed settings. However, the entire guide route is displayed by a single route designation operation. Convenience may be improved by adopting a configuration in which a route can be designated continuously until the user performs an ending operation without designating the route. For example, a route designation completion button may be displayed on the screen, and the route designation completion button may be selected after the input of the designated route is completed.

  Also, in the embodiment, when the display on the screen is smaller than a predetermined scale, it becomes difficult to specify a route. In such a case, after specifying the destination, the screen is enlarged and whether or not the route is specified again. You may make it the structure which asks.

  In the embodiment, the specific point of the guide route is enlarged to improve the user's operability. However, when the guide route is specified, the map scale is large and the route specified by the user is displayed in the display range. When it does not fit within the screen, the scale may be reduced. This eliminates the need for screen scrolling and the like for the user to specify the route, improving operability. As described above, the operability of the user can be improved even when the reduction function is used.

  In the embodiment, when guidance is not required for the route from the current location to the guidance start location, the route guidance may be omitted. For example, when a guidance start point unnecessary button is displayed on the screen and the button is selected, guidance to the guidance start point may be omitted. Or if you arrive near the destination, if you enter the guidance route without passing through the guidance start point, or if the vehicle enters the opposite side of the destination from the guidance start point, The route guidance may be omitted even if there is no user operation. By configuring in this way, unnecessary route guidance can be omitted.

  In the embodiment, the configuration in which the user selects whether the designated start point is the guidance start point or the guidance end point has been described. However, a configuration may be adopted in which switching is automatically performed by an input operation of the user. For example, when the designated start point is set as the guidance start point, the designated start point is determined by touching the screen with a finger, the designated start point is circled without releasing the finger from the screen, and the finger is not released from the screen as it is. The guidance end point may be determined by tracing the route to the specified end point and releasing the finger from the screen at the specified end point.

  Furthermore, in the embodiment, the designated start point is described as the destination, for example, and the designated end point is defined as the current location. However, the designated start point and the designated end point may not be the destination or the current location. For example, one may be a destination and the other may be a desired passage point, or both may be desired passage points.

  Below, the example in case a designation | designated start point and a designation | designated end point are desired passage points is demonstrated using FIGS. 5 to 8 are schematic diagrams illustrating an operation procedure of the panel 32. FIG. Here, it is assumed that the user is in the current location S shown in the screen A ′ of FIG. 5 and sets a guide route in order to move to the destination G.

  First, as shown in FIG. 5, the screen is switched from the screen A ′ to the screen A, and the destination G is set. This setting method is set by the process of S20 in FIG. 2, that is, a method that does not specify a route. For example, the setting is performed by touching the screen A on which the destination G is displayed with a finger. Such a setting method is suitably used when the destination is not displayed on the display screen displaying the current location.

  Next, as shown in FIG. 6, the recommended route L ′ is displayed by the route guidance ECU 1. The recommended route L ′ is displayed by searching for the shortest route among candidate routes, for example. The retrieved recommended route L ′ is displayed so as to be within the screen, and the screen is switched from the screen A in FIG. 5 to the screen B in FIG.

  At this time, the process of S22 and S24 in FIG. 2, that is, the process of enlarging and displaying if there is a point where it is necessary to enlarge and set the route is executed. Thereby, for example, the periphery of the destination is automatically enlarged, and the screen D is displayed in the screen B. Further, for example, the area around a point where the traffic situation changes is automatically enlarged, and the screen C is displayed in the screen B.

  Then, the user refers to the enlarged map information displayed on the screen C and re-designates the desired route. The redesignation can be performed by a procedure of touching the route change point with a finger, tracing the route to be redesignated while touching the screen C, and releasing the finger from the screen C at the route change completion point (arrow Y4). The screen D can be set in the same manner. In this way, the recommended route L ′ can be easily changed by touching the automatically enlarged screen. And the designation | designated start point and designation | designated end point designated in this way become a passage desired point. In addition, when the guide route is changed in this way, it may be considered that the route is greatly changed from the recommended route L ′. Therefore, after the route is changed, for routes other than the changed route, the route to the starting point of the changed route is searched again and a candidate route is set. Alternatively, the direction in which the user traces with the finger when the route is set may be input as the traveling direction of the designated route and set again.

  Next, a method for changing the route of a portion that is not automatically enlarged will be described. First, the location to change the route is specified. For example, as shown in FIG. 6, it can be specified by drawing a circle with a finger (arrow Y6) so as to surround a place where a path expansion is desired. By making such a movement, as shown in FIG. 7, the screen E is newly displayed in the screen B, and the portion designated so as to surround the circle is enlarged and displayed.

  Next, the route is changed using the enlarged screen E. The route change is performed in the same procedure as the route change performed on screens C and D (arrow Y7).

  5, 6 and 7, the recommended route L ′ is changed to the route L as shown in FIG. 8. The locations changed by the screens C, D, and E are locations indicated by C ′, D ′, and E ′, respectively. In addition, as another method for changing the route of a portion that is not automatically enlarged, it may be specified with a normal display, or the entire route may be changed in scale.

  As described above, the route can be changed using the present invention even when the point where the user starts specifying and the point where the specification ends are both desired passing points. Note that routes other than the designated route are automatically set by the route guidance ECU 1, but it is possible to perform route guidance only for a plurality of necessary sections by setting not to guide to the guidance start point, for example.
