[Reroute processing]
The navigation device 100 performs reroute based on a user's input during route guidance, specifically during travel of the vehicle after the start of route guidance.
(First embodiment)
In the first embodiment, the navigation device 100 performs a reroute process when the vehicle approaches the next (most recent) guide point during route guidance. FIG. 2 shows an example of reroute according to the first embodiment. Specifically, FIG. 2 shows a display example of a map and a route when the vehicle approaches an intersection that is the latest guide point during route guidance. The vehicle is at the position indicated by the own vehicle position mark 71 and is approaching an intersection that is the nearest guide point. Now, the guide route 72 has already been set by the route search performed at the time of departure. For some reason, the user wants to go straight at this intersection.

In the first embodiment, when the vehicle enters a predetermined distance from the nearest guide point, the navigation device 100 automatically shifts to the reroute mode. In the reroute mode, the navigation device 100 accepts a touch operation performed on the touch panel of the display 44 as an instruction input for reroute (hereinafter referred to as “reroute input”). In the example of FIG. 2, when the user wants to go straight through the nearest intersection, the user moves the finger 73 in the direction of the arrow 74 while making contact with the display 44. Note that an operation of bringing a finger or the like into contact with the display and flicking it briefly is generally called a flick operation. Called “operation”.

When the navigation device 100 detects the tracing operation in the direction of the arrow 74, the navigation device 100 determines that the user wants to go straight at the nearest intersection, and performs reroute processing. That is, the navigation device 100 sets a new route indicated by the broken line 75. In this way, when the user approaches the nearest guide point, the mode is changed to the reroute mode, and the reroute is performed according to the reroute input by the user, so that the user can perform the reroute with a simple operation without having to stop the vehicle. it can. Moreover, in the conventional auto reroute, the vehicle does not actually reroute unless it travels to a certain extent after traveling straight through this intersection. On the other hand, in the present embodiment, the navigation device 100 immediately reroutes in response to the user's reroute input, so that the reroute can be performed before the vehicle reaches the guide point.

Next, the reroute process according to the first embodiment of the present invention will be described. FIG. 3 is a flowchart of the reroute process according to the first embodiment. This processing is realized by the system controller 20 shown in FIG. 1, specifically, when the CPU 22 executes a program prepared in advance. Also, it is assumed that the destination is set by the user and route guidance is being executed.

First, the system controller 20 determines whether or not the vehicle position of the vehicle is within a predetermined distance from the nearest guide point (step S11). If the vehicle position is not within a predetermined distance from the nearest guide point (step S11), the system controller 20 continues the determination in step S11.

On the other hand, when the vehicle position falls within a predetermined distance from the nearest guide point (step S11: Yes), the system controller 20 sets the reroute mode (step S12). Specifically, the system controller 20 regards subsequent touch inputs to the display 44 as reroute inputs. During normal route guidance, the system controller 20 accepts an input operation for moving a range on the map displayed on the display 44, a so-called scroll operation. That is, when the user moves the finger that touches the display 44, this operation is determined to be a scroll operation for changing the display range of the map. However, in the reroute mode, the system controller 20 determines that the touch input on the display 44 is a reroute input. The reroute input here is an example of the “designating operation related to the traveling direction” and the “second designating operation” in the present invention, and the scroll operation is an example of the “map moving operation” in the present invention.

Next, the system controller 20 detects the connecting road at the nearest guide point (step S13). Details of the processing in step S13 are shown in FIG. Normally, the guide point is an intersection, and the system controller 20 refers to the map data to extract a road (referred to as “connection road”) connected to the intersection that is the guide point, and calculates the angle (step). S21). For example, the system controller 20 calculates the angle of each connecting road when the straight traveling direction of the road on which the vehicle is currently traveling is 0 °.

Next, the system controller 20 determines the connection direction of the extracted connection road (step S22). Specifically, the system controller 20 divides all directions (360 °) around the intersection as a guide point into a predetermined number of directions. FIG. 5 shows an example in which all directions are divided into eight directions based on the current traveling direction of the vehicle. Thus, the system controller 20 determines the connection direction of each connection road based on the angle of each connection road calculated in step S21. In the example of FIG. 5, each connecting road is one of “straight”, “oblique right”, “right turn”, “right front”, “U-turn”, “left front”, “left turn”, “oblique left”. It is determined as either. Note that dividing all directions into eight directions is merely an example, and the directions may be divided into four directions, sixteen directions, and the like.

Next, the system controller 20 determines whether or not the connection direction determination has been completed for all the connection roads extracted in step S21 (step S23). When the determination of the connection direction is not completed for all the connected roads (step S23: No), the process returns to step S21, and the determination for the next connected road is performed. On the other hand, when the determination of the connection direction is completed for all connection roads (step S23: Yes), the process returns to the main routine of FIG.

Next, the system controller 20 determines whether or not a reroute input has been made by the user before the vehicle passes through the nearest guide point (step S14). If no reroute input has been made (step S14: No), the user does not wish to reroute, so the system controller 20 cancels the reroute mode (step S15), and the process returns to step S11. By canceling the reroute mode, subsequent touch input to the display is accepted as a normal scroll operation.

On the other hand, when a reroute input is made (step S14: Yes), the system controller 20 specifies a connecting road in the direction of the reroute input (step S16). Details of the processing in step S16 are shown in FIG. First, the system controller 20 determines the direction of reroute input (step S31). The reroute input is performed by several methods described later, but the system controller 20 determines the designated direction according to the reroute input method. Basically, since the reroute input is performed as a touch input to the map displayed on the display 44, the system controller 20 determines the direction indicated by the touch input on the map as the direction of the reroute input.

Next, the system controller 20 specifies a connection road that matches the reroute input direction (step S32). In the above-described step S13, since the connection road at the latest guidance point is detected, the system controller 20 identifies the connection road whose connection direction matches the reroute input direction among the connection roads at the latest guidance point. .

Next, the system controller 20 determines whether or not there is one connection road whose connection direction matches the reroute input direction (step S33). When there is one matching connecting road (step S33), the system controller 20 selects the connecting road (step S34). On the other hand, if there is not one matching connecting road, that is, if there are a plurality of connecting roads (step S33: No), the system controller 20 selects the connecting road closest to the reroute input direction (step S35). For example, when the reroute input direction is the “straight ahead” direction in FIG. 5 and there are a plurality of connecting roads near the “straight ahead” direction at the nearest guide point, the system controller 20 is closer to 0 ° in the “straight forward” direction. Select the connecting road. That is, when there is no road in the “straight ahead” direction and the connection roads are in the “oblique left” and “left turn” directions, the system controller 20 selects the connection road in the “oblique left” direction. Then, the process returns to the main routine of FIG.

Thus, when the connecting road in the direction of the reroute input is specified in this way, the system controller 20 sets the connecting road in the direction of the reroute input as a stop (Step S17). Specifically, the system controller 20 sets a link corresponding to the identified connecting road, a node corresponding to the end point of the link, or an arbitrary point on the connecting road as a stopover. Then, the system controller 20 searches for a new route passing through the stopover (step S18). Thus, a new route according to the reroute input is set, and the vehicle can travel according to the new route.

Thereafter, the system controller 20 determines whether or not the vehicle has arrived at the destination (step S19). When the vehicle has not arrived at the destination (step S19: No), the process returns to step S11, and the above process is repeated. On the other hand, when the vehicle arrives at the destination (step S19: Yes), the process ends.

Thus, in the reroute process of the first embodiment, when the vehicle enters a predetermined distance from the nearest guide point, the reroute mode is set and the reroute input is accepted. When the user inputs a reroute, a new route that passes through the connecting road in the designated direction is re-searched. Therefore, the user can perform a reroute with a simple operation without stopping the traveling of the vehicle near the guidance point during the route guidance.

In the above embodiment, if there are a plurality of connecting roads that match the designated direction of the reroute input in step S35 of FIG. 4B, the system controller 20 selects the connecting road that is closest to the direction of the reroute input. ing. Instead, when there are a plurality of connecting roads that match the designated direction of the reroute input, the reroute may not be performed. Thereby, when the direction designated by the user's reroute input is ambiguous, it is possible to prevent the user from being rerouted in an unintended direction.

Next, the reroute input method in the first embodiment will be described. There are several possible reroute input methods. The first to fourth methods described below correspond to the “second designation operation” in the present invention.

The first method is a method of designating the direction in which the user wants to proceed at the nearest guide point by a tracing operation of a contact body such as a finger, as indicated by an arrow 74 in FIG. In this case, the system controller 20 determines the direction of the tracing operation detected by the touch panel of the display 44 as the direction of the reroute input.

The second method is a method of designating one point on the road connected to the intersection of the guide points by touch input as indicated by a mark 78 in FIG. In this case, the system controller 20 sets the touched point as a stop and searches for a new route.

The third method is a method in which the navigation device 100 displays options on the direction to be rerouted on the display 44 and allows the user to select. Specifically, when the system controller 20 enters the reroute mode, the system controller 20 displays a direction icon indicating the direction of the connected road that can travel at the nearest guide point on the display 44. For example, when the vehicle can travel in three directions, ie, straight ahead, right turn, and left turn, at the nearest guide point, the system controller 20 displays direction icons such as three arrows corresponding to these three directions on the display 44. . When the user touches one of the displayed direction icons, the system controller 20 determines that the direction is a reroute input direction.

The fourth method uses a so-called air gesture. In any of the above first to third methods, the user makes a reroute input by bringing a contact body such as a finger into contact with the touch panel of the display 44. However, in the fourth method, the user moves near the display 44. A finger as an input body is moved in a certain direction in the air without touching the display 44. A plurality of proximity sensors and the like are provided around the display 44, and the direction in which the user moves the finger is detected based on the outputs of the plurality of proximity sensors. The system controller 20 determines the direction as the reroute input direction. By providing a certain number of proximity sensors, it is possible to distinguish and detect inputs in about eight directions shown in FIG.

(Second embodiment)
Next, a second embodiment of the reroute process will be described. In the first embodiment, the reroute is performed when the vehicle approaches the nearest guide point. On the other hand, in the second embodiment, the reroute is performed not only when the vehicle approaches the nearest guide point but also at any position, that is, at an arbitrary timing.

FIG. 6 shows an example of reroute processing according to the second embodiment. Now, the vehicle is at the position of its own vehicle position mark 81 and is traveling according to a preset guide route 82. Here, it is assumed that the user wants to drop in at the store 88 indicated by a broken line. It is assumed that the vehicle can enter the store 88 only by making a left turn because there is a median strip on the road in front of the store 88.

In this case, as shown in FIG. 6, the user performs a tracing operation in the direction indicated by the arrow 84 on the road in front of the store 88. The navigation device 100 detects this stroking operation as a reroute input, determines that the user wants to travel on the road in front of the store 88 in the direction of the arrow 84, and re-searches for a new route 85 including such a route. That is, the new route 85 is a route obtained by adding a route (hereinafter referred to as “intermediate route”) that travels in the direction of the arrow 84 on the road in front of the store 88. Thereby, the user can enter the store 88 by making a left turn. Note that the above example is merely an example, and in the second embodiment, reroute input for traveling in an arbitrary direction on an arbitrary position on the map can be performed.

In the first embodiment, when the vehicle enters within a predetermined distance from the nearest guide point, the system controller 20 sets the navigation device 100 to the reroute mode, and receives subsequent touch inputs to the display 44 as reroute inputs. As a matter of fact, a normal scroll operation and a reroute input are distinguished. In contrast, in the second embodiment, the reroute input is always accepted, not only when the vehicle approaches the nearest guide point, but it is necessary to distinguish the reroute input from the scroll operation.

Therefore, in the second embodiment, the reroute input is performed by a method different from the scroll operation. For example, a normal scroll operation is an operation (race operation) for touching a certain position on the map with one finger and moving the finger. On the other hand, the reroute input in the second embodiment is an operation in which a plurality of (for example, two) fingers touch a certain position on the map and move these fingers simultaneously (hereinafter referred to as “multi-finger tracing operation”). Call it.) Alternatively, in the reroute input of the second embodiment, a certain finger touches a certain position on the map for a predetermined time or longer (so-called “long press”), and then moves the finger (hereinafter, “after long press”). This is also referred to as “tracing operation”). As described above, in the second embodiment, the reroute input operation is different from the normal map scroll operation (hereinafter also referred to as “special reroute input”), so that the route guidance is being performed. It is possible to distinguish between reroute input and scroll operation at an arbitrary timing. In the second embodiment, a position unrelated to the vehicle position of the vehicle is designated by the reroute input. Therefore, the reroute input indicates the road to be traveled by the reroute and the traveling direction (that is, the road). This is an operation for designating two directions, i.e., in which direction along the road. The reroute input here is an example of the “designating operation related to the traveling direction” and the “first designating operation” of the present invention, and the scroll operation is an example of the “map moving operation” of the present invention.

In the second embodiment, the reroute mode is not set as in the first embodiment even when the vehicle approaches the nearest guide point. In other words, whether the vehicle is approaching the nearest guide point or not, reroute can be performed by the above-described special reroute input.

FIG. 7 is a flowchart of the reroute process of the second embodiment. This processing is realized by the system controller 20 shown in FIG. 1, specifically, when the CPU 22 executes a program prepared in advance. Also, it is assumed that the destination is set by the user and route guidance is being executed.

First, the system controller 20 determines whether or not a reroute input has been made by the user (step S41). The reroute input here is the above-mentioned special reroute input. If no reroute input has been made (step S41: No), the process proceeds to step S45.

On the other hand, when the reroute input is made (step S41: Yes), the system controller 20 acquires the road designated by the reroute input and the traveling direction of the road (step S42). Next, the system controller 20 sets the road designated by the reroute input as a stoppage (step S43), and searches for a new route that travels in the traveling direction designated by the reroute input (step S44). In this way, a new route including a midway route traveling in a desired direction at a point desired by the user is obtained.

Next, the system controller 20 determines whether or not the vehicle has arrived at the destination (step S45). If the vehicle has not arrived at the destination (step S45: No), the process returns to step S41, and the above process is repeated. On the other hand, when the vehicle has arrived at the destination (step S45: Yes), the process ends. As described above, according to the reroute process of the second embodiment, the user can perform reroute so that the user travels in a desired direction in a desired direction at an arbitrary timing during route guidance.

In the above example, as the special reroute input in the second embodiment, a multi-finger stroking operation or a stroking operation after a long press is given, but the application of the present invention is not limited thereto. For example, when the user touches the display 44 with a plurality of fingers or presses and holds with one finger, the system controller 20 determines that the road is a designated road and sets the direction in which the road can travel on the road. A direction icon to be displayed may be displayed on the display 44, and the user may designate a traveling direction by selecting one of the direction icons.

[Modification]
Next, a modified example of the present invention will be described.
(Modification 1)
In the above second embodiment, reroute is performed by a special reroute input such as a multi-finger tracing operation regardless of the position of the vehicle. Instead, the first embodiment and the second embodiment may be combined. That is, first, as in the first embodiment, when the vehicle approaches the nearest guide point, the reroute mode is automatically set, and during the reroute mode, the first to fourth described in the first embodiment are performed.
