That is, it is specified based on the parking brake state signal PBS whether or not the vehicle is parked, and in particular whether or not the vehicle is running (including a temporary stop state).

  The operation unit 190 includes a switch operation unit 192 and a touch panel operation unit 194. In addition to the operation switch 13 described above, the switch operation unit 192 includes a switch circuit board (not shown) that converts the operation of the operation switch 13 into an electrical signal and outputs the switch signal SS to the control unit 100. In addition to the touch panel 32 described above, the touch panel operation unit 194 includes a touch panel circuit board (not shown) that converts the operation of the touch panel 32 into an electrical signal and outputs the touch signal TS to the control unit 100. The touch signal TS includes information indicating the coordinates of the touch operation location on the surface of the touch panel 32, whereby the control unit 100 can identify the touch operation location on the touch panel 32. Here, the control unit 100 inputs the switch signal SS and the touch signal TS from the operation unit 190 when the parking brake state signal PBS indicates that the vehicle is not parked for the purpose of safety of traveling. When the vehicle is not parked, various operations are especially prohibited while the vehicle is running.

  Next, the display mode of the display unit 140 will be described. As shown in FIG. 6, the navigation apparatus 1 has a full screen display for displaying a map or TV image on the entire display surface 31A of the liquid crystal panel 31, and a map on the display surface 31A of the liquid crystal panel 31 as shown in FIG. It has two display modes: a two-screen display that is displayed simultaneously with a TV image. In the two-screen display, a part of the display area of the display surface 31A is divided into a substantially rectangular shape to form a small window screen 31B, a map is displayed on the entire display surface 31A, and a TV image is displayed on the small window screen 31B. Is displayed.

  The small window screen 31B is configured such that the display area can be enlarged or reduced, and the display position can also be changed. Specifically, the operation unit 190 (the switch operation unit 192 or the touch panel operation unit 194) is operated to instruct to enlarge or reduce the display area of the small window screen 31B. Is received, the drawing command DSS based on this instruction is output to the display unit 140 to change the display area of the small window screen 31B.

  The display position of the small window screen 31B in the display surface 31A can be changed by a touch operation on the touch panel 32. More specifically, when the liquid crystal panel 31 is in a two-screen display state, a touch operation is performed on the edge (peripheral portion) of the touch panel 32, or a touch operation is performed on the display area of the small window screen 31B. The display position of the window screen 31B can be changed.

  That is, as shown in FIG. 8, in the two-screen display state, the edge portion 33 of the touch panel 32 functions as a movement button 34 for moving the small window screen 31B and corresponds to the display area of the small window screen 31B. The area of the touch panel 32 functions as a drag operation button 35 for dragging the small window screen 31B. Specifically, the vicinity of the upper side 32A of the touch panel 32 functions as an upward movement button 34A for moving the small window screen 31B upward, and similarly, the vicinity of the right side 32B is the right direction movement button 34B. The vicinity of the lower side 32C is the downward movement button 34C, the vicinity of the left side 32D is the left direction movement button 34D, the vicinity of the upper right corner 32E is the upper right direction movement button 34E, the vicinity of the lower right corner 32F is the lower right direction movement button 34F, and the vicinity of the lower left corner 32G is the lower left area. The direction moving button 34G and the vicinity of the upper left corner 32H function as the upper left direction moving button 34H. As described above, the direction in which the movement buttons 34A to 34H are arranged as viewed from the center O of the display surface 31A matches the direction in which the movement buttons 34A to 34H move the small window screen 31B. . Therefore, it is possible to intuitively identify the movement buttons 34A to 34H without clearly indicating them by display or the like, and the movement operation of the small window screen 31B becomes easy. Moreover, since the display of each movement button 34A-34H is unnecessary, the map displayed on 31 A of display surfaces by the display of these movement buttons 34A-34H is not hidden.

  FIG. 9 is a diagram showing button settings 300 that define the coordinate ranges A1 to A9 on the touch panel 32 and the operation contents of the movement buttons 34A to 34H and the drag operation buttons 35. Stored in advance in the storage unit 110 (for example, the ROM 102). When the touch panel 32 is touch-operated when the screen display is in the two-screen display state, the control unit 100 specifies the operation content from the touch operation location (coordinate value) based on the button setting 300. Here, since the coordinate range A9 of the drag operation button 35 changes according to the display position and display area of the small window screen 35, when the display screen is in the two-screen display state, the small window screen 31B at that time is displayed. The display area is captured as the initial value of the coordinate range A9 of the drag operation button 35. Each time the display position or area of the small window screen 31B is changed, the coordinate range A9 of the drag operation button 35 is updated.

  Moreover, in this Embodiment, it is set as the structure which changes the moving distance of the small window screen 31B according to the touch time t (pressing time) of each moving button 34A-34H. Specifically, as shown in FIG. 10, when the touch time t is longer than a reference time Tth (for example, about 1 to 2 seconds) (hereinafter, such an operation is referred to as “long press operation”), a small window is moved by the moving distance D1. When the screen 31B moves and the touch time t is shorter than the reference time Tth (hereinafter, this operation is referred to as “short press operation”), the small window screen 31B moves by a movement distance D2 shorter than the distance D1. Assuming that pixels are used as the units of these moving distances D1 and D2, the moving distance D1 is set to 10 pixels, and the moving distance D2 is set to 1 pixel.

  Therefore, when a long press operation is performed on each of the movement buttons 34A to 34H, the operated movement button 34 (upper left movement button 34H in the illustrated example) is moved from the center O of the display surface 31A as shown in FIG. When the small window screen 31B is moved greatly by a relatively long moving distance D1 (10 pixels) in the direction in which it is arranged, and when a short press operation is performed, as shown in FIG. The small window screen 31B is moved in small increments by a relatively short moving distance D2 (1 pixel) in the direction in which the moving button 34 (upper left direction moving button 34H in the illustrated example) is arranged as viewed from the center O of the display surface 31A. . As a result, it is possible to roughly adjust and finely adjust the display position of the small window screen 31B.

  Further, as shown in FIG. 13, when the display area of the small window screen 31B, that is, the drag operation button 35 is touched and the touched finger slides on the display surface 31A (so-called drag operation), this sliding The small window screen 31B moves in accordance with. As a result, it is possible to perform a moving operation as if the small window screen 31B is moved with a finger, and the moving operation of the small window screen 31B can be performed more intuitively.

  Next, the operation of the navigation device 1, in particular, the movement operation of the small window screen 31B will be described in detail with reference to FIG. FIG. 14 is a flowchart of the small window screen moving process. As shown in this figure, the control unit 100 determines whether or not the screen display of the display unit 140 is in a two-screen display state in which a TV image is displayed on the small window screen 31B together with the map display (step S1). If it is not a two-screen display (step S1: NO), the process ends because there is no movement of the small window screen 31B. On the other hand, in the case of the two-screen display state (step S1: YES), the coordinate value of the display area of the small window screen 31B is acquired in order to set the display area of the small window screen 31B as the coordinate range A9 of the drag operation button 35. Then, it is stored in the SRAM 106 of the storage unit 110 (step S2).

  Then, the control unit 100 determines whether or not the touch signal TS is output from the touch panel operation unit 194, and determines whether or not a touch operation is performed on the touch panel 32 (step S3). When there is no touch operation (step S3: NO), the control unit 100 returns the processing procedure to step S1, and repeats the confirmation of the two-screen display state and the confirmation of the presence or absence of the touch operation. On the other hand, when there is a touch operation (step S3: YES), the control unit 100 executes the following process to specify the operation content of the touch operation. That is, the control unit 100 determines whether or not the edge portion 33 of the touch panel 32 (more specifically, any of the movement buttons 34A to 34H provided on the edge portion 33 of the touch panel 32) is touch-operated. Is determined based on the touch coordinate information included in (step S4). When the touched portion is not the edge 33 (step S4: NO), the control unit 100 next determines whether or not the inside of the display area of the small window screen 31B has been touched (step S5). If the touch-operated portion is not within the display area of the small window screen 31B (step S5: NO), the touch operation operates any of the movement buttons 34A to 34H and the drag operation button 35. If the operation is invalid, the process returns to step S1.

  On the other hand, when the touched portion is the edge 33 (step S4: YES), the control unit 100 performs an edge operation for moving the small window screen 31B based on the touch operation of the edge 33. A moving process is executed (step S6). If the touched part is within the display area of the small window screen 31B, a drag operation process for dragging the small window screen 31B is executed (step S6). S7).

In the edge operation movement process, as illustrated in FIG. 15, the control unit 100 determines which of the movement buttons 34 </ b> A to 34 </ b> H provided on the edge 33 of the touch panel 32 is touch-operated and the coordinates of the touch signal TS. A determination is made based on the information (step S60), and the direction in which the small window screen 31B is to be moved is specified based on the operation content previously associated with the movement button 34 (see FIG. 9) (step S61). .
Next, the control unit 100 determines whether the touch operation is a long press operation or a short press operation in order to specify a distance to move the small window screen 31B (step S62). That is, in step S72, the control unit 100 counts the touch time t from when the touch operation is detected until the finger is released from the touch panel 32, and when the touch time t is longer than the reference time Tth. The touch operation is determined to be a long press operation, and otherwise, it is determined to be a short press operation.

  When the touch operation is a long press operation (step S62: long press operation), the control unit 100 moves the small window screen 31B by 10 pixels in the movement direction specified in step S61 (step S61). Is a short press operation (step S62: short press operation), the control unit 100 moves the small window screen 31B by one pixel in the movement direction specified in step S61. As a result, when a long press operation is performed, as shown in FIG. 11, the small window screen 31B moves greatly in the same direction as the direction in which the movement button 34 is arranged when viewed from the center O of the display surface 31A. In addition, when a short press operation is performed, as shown in FIG. 12, the small window screen 31B is chopped in the same direction as the direction in which the movement button 34 is arranged when viewed from the center O of the display surface 31A. Will move. When the touch time of the movement button 33 is several times the reference time Tth described above, the small window screen 31B may be repeatedly moved by the movement distance D1 while the touch operation is being performed. good.

  Further, in the drag operation process, as shown in FIG. 16, the control unit 100 determines the amount of change and the direction of the change in the touch operation portion during the time Δt (for example, 0.1 second) as the touch signal TS. (Step S70), and the small window screen 31B is moved in accordance with the amount of change and the direction of the change (Step S71). Specifically, in step S70, the control unit 100 determines the amount of change and change of the touch operation location based on the current coordinate value of the touch operation location and the coordinate value of the touch operation location after the time Δt has elapsed. The direction is calculated by the three-square theorem, vector calculation, or the like. In step S71, the shift amount is set as the shift amount of the small window screen 31B, and the shift direction is set as the shift direction of the small window screen 31B. Move 31B.

  Then, the control unit 100 determines whether or not the touch operation is still continued based on the touch signal TS (step S72), and when the touch operation is continued (step S72: YES), the small window In order to specify the moving amount and moving direction of the screen 31B, the processing procedure returns to step S70. If the touch operation has been completed (step S72: NO), the control unit 100 ends the process because there is no need to move the small window screen 31B. As a result of the above processing, when the display area of the small window screen 31B is touched and a drag operation is performed such that the touched finger slides on the surface of the touch panel 32, as shown in FIG. The display screen moves according to the movement of the screen.

  As described above, according to the navigation device 1 of the present embodiment, a map is displayed on the entire display surface 31A of the display unit 140, and a TV image is simultaneously displayed on the small window screen 31B formed on the display surface 31A. When the touch panel 32 is touch-operated during the display, the small window screen 31B on which the TV image is displayed is moved based on the touch-operated portion, so that the display position of the small window screen 31B is displayed. This small window screen 31B can be easily moved without calling up a setting screen for setting and performing a complicated operation procedure such as setting, and the convenience of the navigation device 1 can be enhanced.

  In particular, when the current position displayed on the map or the place to be confirmed is hidden behind the small window screen 31B, the small window screen 31B can be moved simply by touching the touch panel 32. , The hidden part can be displayed.

  Further, according to the navigation device 1 of the present embodiment, when the edge portion 33 of the touch panel 32 is touch-operated, the TV image is displayed in substantially the same direction as the direction from the center of the touch panel 32 to the operation location of the touch operation. Since the displayed small window screen 31B is moved, when the user moves the small window screen 31B in a desired direction, a touch operation is performed on a portion corresponding to the direction on the edge 33 of the touch panel 32. Therefore, the touch operation for moving the small window screen 31B can be performed intuitively.

  In particular, it is possible to intuitively grasp which position of the edge portion 33 of the touch panel 32 is moved to which direction the small window screen 31 </ b> B is moved. Therefore, a movement button provided on the edge portion 33 of the touch panel 32. 34 is not required to be displayed on the display surface 31A, and the display surface 31A can be used effectively.

  Furthermore, according to the navigation device 1 of the present embodiment, the touch operation is divided into the long press operation and the short press operation according to the touch time t during which the touch panel 32 is touched. Since the movement amount of the small window screen 31B is made smaller during the short press operation than when the long press operation is performed, the small window screen 31B is moved roughly in small increments. The operation can be used easily. Further, since the small window screen 31B can be moved in small increments, fine adjustment of the display position of the small window screen 31B can be easily performed.

  Further, according to the navigation device 1 of the present embodiment, when the display area of the small window screen 31B on which the TV image is displayed is touched and the touched location moves on the surface of the touch panel 32 (so-called dragging).
