A control unit 20, a display data generation unit 21, a communication unit 22, a control content setting unit 23, and the like are provided.
[0014]
Although not shown, the navigation device is provided with a storage unit that stores various types of information such as map information, and a position detection unit that detects the current location of the vehicle (vehicle position). The information stored in the storage unit includes regulatory information such as one-way traffic and traffic closure that restricts vehicle traffic, and facility information related to locations such as parking lots, restaurants, and convenience stores. In addition, the navigation device of this embodiment has a route guidance function for guiding a route to a destination.
[0015]
The input unit 10 is for the user to instruct the scroll (movement amount, movement direction) of the map displayed on the display unit 19 and the movement of the cursor position (movement amount, movement direction) on the map. As shown in FIG. 2, the input unit 10 is installed on an armrest or the like in the vehicle interior so that the user can easily operate it. The input unit 10 of the present embodiment is configured with a joystick including an operation lever 11. Motors 12 and 13 are connected to the X-axis and Y-axis of the operation lever 11, respectively. These motors 12 and 13 constitute a drive unit that applies a predetermined driving force to the input unit 10, that is, the X axis and the Y axis of the operation lever 11.
[0016]
Encoders 14 and 15 are provided on the X axis and the Y axis of the operation lever 11, respectively. These encoders 14 and 15 detect the positions of the X and Y axes of the operation lever 11. The output signals of the encoders 14 and 15 are output to the movement amount calculation unit 16. The movement amount calculation unit 16 calculates the position (movement amount, movement direction) of the operation lever 11 based on the signals from the encoders 14 and 15 and outputs the position to the driving force calculation unit 17.
[0017]
The driving force calculation unit 17 calculates what driving force is applied to each of the motors 12 and 13 based on a signal from the movement amount calculation unit 16 and a signal from the control content setting unit 23 described later. Output to the motor control unit 18. The driving force calculation in the driving force calculator 17 will be described later. The motor control unit 18 outputs a control signal to each of the motors 12 and 13, and the motors 12 and 13 give a predetermined driving force to the operation lever 11 according to the control signal.
[0018]
The display unit 19 is configured to display information including a map on the screen by a signal from the display control unit 20 and to change the display range of the map. As shown in FIG. 2, the display part 19 is arrange | positioned ahead of the vehicle interior. A vehicle mark indicating the vehicle position is displayed on the map of the display unit 19, and a cursor mark that moves in accordance with the map scroll is displayed. The cursor moves on the map corresponding to the position (movement amount, movement direction) of the operation lever 11 of the input unit 10, and serves as a point of interest on the map. In order to improve operability and visibility, the screen display on the display unit 19 moves only the cursor within the movable range of the cursor set near the center of the screen, and tries to move the cursor outside the movable range of the cursor. At that time, the display is controlled to scroll the map.
[0019]
The screen data displayed on the display unit 19 is generated by the display data generation unit 21 from map information, facility information, etc. stored in a storage device (not shown). The data transmitted from the display data generation unit 21 to the display control unit 20 includes regulation information such as one-way traffic and facility information indicating a position such as a parking lot.
[0020]
Facility information does not relate to a specific location but relates to a specific type of facility in which there are a plurality of similar types such as parking lots. The navigation apparatus according to the present embodiment is configured to be able to search for a facility of the type desired by the user from the facility information, and can provide route guidance using the facility targeted for the search as a destination.
[0021]
In addition, by communicating with the outside through the communication unit 22, the latest information such as temporary regulation information such as construction and accidents and the current vacant information of the parking lot can be acquired in real time. It is output to the display control unit 20. The display data generation unit 21 and the communication unit 22 constitute a restriction information acquisition unit of the present invention.
[0022]
The display control unit 20 outputs the restriction information and facility information obtained from the display data generation unit 21 and the communication unit 22 to the control content setting unit 23. Based on the restriction information, the control content setting unit 23 sets a place where vehicle traffic such as one-way traffic is restricted as a restriction part that restricts cursor movement and map scrolling on the display unit 19. Furthermore, in the control content setting unit 23, when a desired facility (parking lot or the like) is searched from the facility information by the user and route guidance is provided for the facility to be searched, the search target facility is displayed on the map on the display unit 19. Set as a guidance area to induce scrolling.
[0023]
The control content setting unit 23 outputs the control content to the driving force calculation unit 17. As described above, the driving force calculation unit 17 calculates the driving force applied to the input unit 10 based on the signal from the movement amount calculation unit 16 and the signal from the control content setting unit 23. Specifically, when the user moves the cursor to the restriction location and performs an operation of moving the display range of the map, a driving force in the direction opposite to the user's operation direction is given to the input unit 10. Further, when performing route guidance for the search target facility, a driving force is given to the input unit 10 along the guidance route toward the search target facility.
[0024]
Thereby, when the user performs an operation of moving the cursor in the direction of entering the restricted portion, a predetermined resistance for returning the operation lever 11 to the original direction with respect to the operation of the operation lever 11 by the user. Power is given. Further, when performing route guidance for the search target facility, a predetermined pulling force is applied to pull the operation lever 11 in the route direction toward the search target facility.
[0025]
Hereinafter, the operation of the navigation apparatus having the above configuration will be described with reference to the flowchart of FIG. First, a map of the position specified by the current position or destination input is displayed on the display unit 19 (S10).
[0026]
Next, the control content setting unit 23 sets the control content from the control information centered on this position (S11). The contents of this regulation are based on the principle that the cursor moves on the road, can move smoothly without resistance on the road, and give strong resistance to movement outside the road. For example, at one-way exits, roads closed during construction, entrances to roads where vehicle traffic is temporarily restricted in pedestrian heaven, etc., strong resistance is given as in the case of moving outside the road. . Conversely, when a parking lot, a gas station, a restaurant, or the like is being guided, the cursor is set to give a driving force so as to be drawn on the road.
[0027]
Next, it is determined whether or not the operation lever 11 has been operated, and the process waits until the lever is operated (S12). When the lever is operated, the movement amount calculation unit 16 calculates the position of the operation lever 11 (S13). The position of the operation lever 11 corresponds to the position of the cursor on the screen, and the state where the cursor is at the center of the screen is used as a reference. When the operation lever 11 is operated by the user, the movement amount calculation unit 16 calculates the movement direction and the movement amount of the operation lever 11.
[0028]
Next, the driving force calculation unit 17 calculates a planned cursor movement position corresponding to the amount of movement of the operation lever 11 (S14), and necessary driving of the motors 12 and 13 to be applied to the input unit 10 based on the planned cursor movement position. The force is calculated (S15). Based on the necessary driving force, the motors 12 and 13 are driven by a signal from the motor control unit 18 (S16). Specifically, when the cursor movement planned position is a road that can travel, the driving force is set to 0 to facilitate the operation of the operation lever 11 in that direction. On the contrary, when the cursor movement planned position is not a road that can be traveled, a strong driving force is generated on the opposite side of the user's operation direction to generate a resistance force, and the movement in that direction is restricted. Furthermore, when guiding a specific facility such as a parking lot, a gas station, a restaurant, etc., a driving force is generated in the direction of the guidance route to generate a pulling force, and the movement in that direction is guided.
[0029]
Next, the screen display after the cursor movement is performed (S17). Until the lever operation is completed, the processes in steps S12 to S17 are repeated (S18).
[0030]
Furthermore, the operability can be improved by controlling as follows. That is, when the resistance force is set to 0 when the user is not operating, the operation lever 11 moves freely. Therefore, the operation lever 11 moves as the vehicle starts, stops, curves, etc., as if it were operated against the user's intention. Shows behavior. In order to prevent this, even when the vehicle moves as described above, a weak resistance force that does not move the operation lever 11 is generated in all directions.
[0031]
As a result, even if the operation lever 11 moves even a little, it returns to its original position, and the operation lever 11 maintains its position even when the user releases the hand. The user operates with a force that overcomes this weak resistance. And the feeling of operation that there is a wall is obtained by increasing the resistance in proportion to the amount of movement.
[0032]
In addition, if the hand is suddenly released while a strong resistance force is generated, the operation lever 11 may move greatly due to the generated resistance force. In order to prevent this, the resistance force is gradually weakened when it moves in the direction of the resistance force, and when it moves largely, a resistance force is generated in the opposite direction so that the control lever 11 does not move too much. Control. Similarly, the pull-in force is controlled to suppress a large movement.
[0033]
As described above, according to the navigation device of the present embodiment, when the user tries to move the cursor to the restricted location, the cursor is moved to the restricted location by applying a predetermined driving force (resistance force) to the input unit 10. And map scrolling can be restricted. Thereby, it can tell a user's tactile sensation and can recognize a regulation part, and it can prevent giving a misunderstanding that a user can advance to a regulation part where vehicles run is regulated.
[0034]
In addition, when guiding a specific facility, by giving a predetermined driving force (retraction force) along the guidance route, it is possible not only to guide the route on the screen but also to convey to the user's tactile sensation. , Can tell the positional relationship more accurately. Furthermore, if the latest parking lot availability information etc. are acquired using a communication function, a user can be guide | induced efficiently.
