  Next, the display mode of the display unit 140 will be described. As shown in FIG. 6, the navigation device 1 has two screens 31 </ b> A on the liquid crystal panel 31 such as a full screen display for displaying a map or a TV image on the entire display surface 31 </ b> A of the liquid crystal panel 31. A display area is divided into two display modes: a map is displayed in one display area and a two-screen display in which a TV image is displayed in the other display area. In the following description, in the two-screen display, a display area where a map is displayed is referred to as a map display area MA, and an area where a TV video is displayed is referred to as a TV video display area TA. As a display mode of the two-screen display, there may be a mode in which a small window is formed in the display surface 31A and a TV video is displayed in the small window. In this aspect, the TV image display area TA formed as a small window overlaps with the map display area MA.

  In the two-screen display, the area ratio between the map display area MA and the TV video display area TA can be changed by the operation of the operation unit 190 (the switch operation unit 192 or the touch panel operation unit 194). In such a case, the control unit 100 outputs the drawing command DSS instructing the change of the area ratio to the display unit 140, and changes the area ratio between the map display area MA and the TV video display area TA. Thereby, it is possible to appropriately enlarge and display the map and the TV image that the user wants to pay attention to.

  Further, in the two-screen display, in order to prevent the driver from being distracted by the TV image, as shown in FIG. 8, while the vehicle is traveling, the TV image display area TA is replaced with the TV image. For example, a still image such as an illustration is displayed and the TV image is not displayed. Specifically, when the screen display state of the display unit 140 is the two-screen display state, the control unit 100 displays the display unit 140 when the parking brake state signal PBS indicates that the vehicle is no longer in the parking state. The output of the TV image to the TV image is stopped, and still image data to be displayed in the TV image display area TA is output instead of the TV image. At this time, the control unit 100 continues to output the TV sound to the sound output unit 135. As a result, when the vehicle is traveling, when the display screen is in a two-screen display state, the TV image is not displayed in the TV image display area TA and cannot be viewed, but the TV sound can be heard. .

  In the present embodiment, as shown in FIG. 9, the vehicle stops while the screen display is in the two-screen display state and the TV image on the TV image display area TA is not displayed. When the parking lot search button 33 is touch-operated, the control unit is configured so that the area corresponding to the TV video display area TA on the surface of the touch panel 32 functions as the parking lot search button 33. 100 starts to search for parking lots around the vehicle. Therefore, when the driver wants to see the TV image from the content of the TV sound, etc., the vehicle is temporarily stopped on the road shoulder or the like, and the parking lot search button 33 is touch-operated to It is possible to find a parking lot easily and quickly. Hereinafter, with reference to FIG. 10, the processing operation for the parking lot search button 33 will be described in detail.

  FIG. 10 is a flowchart showing the procedure of the parking lot search button process. First, the control unit 100 performs the following process to determine whether or not the parking lot search button 33 should function. That is, as shown in FIG. 10, the control unit 100 determines whether or not the screen display of the display unit 140 is in a two-screen display state of a TV image and a map (step S1) and is not in a two-screen display state. In the case (step S1: NO), it is not necessary to make the parking lot search button 33 function, so the processing is ended as it is. On the other hand, when it is in the two-screen display state (step S1: YES), the control unit 100 determines whether or not the vehicle is parked based on the parking brake state signal PBS (step S2). When the vehicle is parked (step S2: YES), the TV image is displayed in the TV image display area TA, and the parking lot search button 33 does not need to function. Return to step S1.

  On the other hand, when the vehicle is not parked (step S2: NO), the control unit 100 determines whether or not the vehicle is stopped based on the vehicle speed signal CSS (step S3). When the vehicle is not stopped (step S3: NO), since the operation to the navigation device 1 is prohibited, it is not necessary to cause the parking lot search button 33 to function, so the control unit 100 performs the processing procedure at step S1. Return to. When the vehicle is stopped (step S3: YES), an area corresponding to the TV image display area TA on the surface of the touch panel 32 functions as the parking lot search button 33 and can be operated (step S4). . That is, in this step S4, the control unit 100 acquires the coordinate range of the current TV video display area TA, and obtains the coordinate range and the coordinate value of the parking lot search button 33 that should function on the surface of the touch panel 32. Associate. Thereby, the control unit 100 recognizes that the touch operation on the display area of the TV video display area TA is the touch operation on the parking lot search button 33.

  As a result of the above processing, when the vehicle is stopped when the display screen of the display unit 140 is in the two-screen display state and the TV image is not displayed in the TV image display area TA, as shown in FIG. An area corresponding to the TV image display area TA on the touch panel 32 functions as a parking lot search button 33, and the parking lot search button 33 can be operated.

  After enabling the parking lot search button 33 to be operable in this way, the control unit 100 determines whether or not the parking lot search button 33 is touched based on the touch signal TS (step S5). When there is no touch operation (step S5: NO), since it is not necessary to perform parking lot search, the control part 100 returns a process sequence to step S1. On the other hand, when there is a touch operation (step S5: YES), the control unit 100 executes the following process to search for a parking lot around the vehicle.

  That is, the control unit 100 specifies the current host vehicle position based on the position detection signal PS from the position detection unit PS (step S6). Next, the control unit 100 selects a parking lot (including a parking space) existing within a predetermined distance from the current vehicle position based on map data and various search data stored in the main storage unit 120. To search (step S7). In step S <b> 7, the control unit 100 searches for a corresponding parking lot in the order closer to the current vehicle position with a predetermined number (for example, 10) as an upper limit.

  Next, the control unit 100 executes a search result display process for displaying the search result in step S7 on the display unit 140 (step S8). In this search result display process, the parking lots obtained as a result of the search are displayed in the TV video display area TA, and the locations of these parking lots are displayed on the map. Furthermore, the display mode of the search result on the TV video display area TA is changed according to the size of the TV video display area TA.

  Specifically, as shown in FIG. 11, the control unit 100 first acquires coordinate values (coordinate ranges) on the display surface 31A of the current TV video display area TA (step S80). And the control part 100 judges whether the magnitude | size of TV image display area TA specified based on this coordinate value is large enough to display the name of a parking lot (step S81). When the TV image display area TA is sufficiently wide (step S81: YES), the control unit 100 uses the name and identification number of the parking lot obtained as a result of the search in step S7 as shown in FIG. The TAs are displayed in order from the own vehicle position, and the locations of these parking lots are displayed on the map in the map display area MA so that they can be identified (step S82). On the other hand, when the TV image display area TA is narrow (step S81: NO), the control unit 100 identifies each parking lot obtained as a result of the search in step S7, as shown in FIG. Are displayed on the TV image display area TA in order from the vehicle position, and the locations of these parking lots are displayed on the map of the map display area MA so that they can be identified (step S83).

  In this way, the parking lots around the vehicle are displayed in the TV image display area TA in the closest order, and the locations of those parking lots are displayed on the map, so that the driver can find out which location away from the current location. Can recognize if there is a parking lot. Further, the search result can be appropriately displayed by changing the display mode of the search result displayed in the TV video display area according to the size of the TV video display area TA. In particular, when the TV image display area TA is small, the display result of the search result is simplified so that only the parking lot identification number is displayed, thereby preventing the visibility of the search result from being lowered. Furthermore, even when only the parking lot identification number is displayed in the TV image display area TA as a search result, the name of each parking lot is displayed on the map as shown in FIG. Thus, the driver can easily recognize these parking lots. If the TV image display area TA is sufficiently large, in addition to the name of the parking lot, information on whether or not it is a toll parking lot, parking fees, and other information that is useful for selecting a parking lot should be displayed. Also good.

  Now, returning to FIG. 10 described above, the control unit 100 displays the search result by the search result display process, and then any one of the parking lots obtained as a result of the search by the driver or the like is the destination (already other If the destination is set, it is determined whether or not the destination is set (step S9). Specifically, in step S9, the control unit 100 determines, based on the touch signal TS, whether or not a portion corresponding to the TV image display area TA on the surface of the touch panel 32 has been touched, and the touch is performed. If operated, it is determined which parking lot is touched. If any parking lot displayed as a search result is touched, it is determined that the parking lot has been set as the destination.

  If the destination is not set as a result of the determination in step S9 (step S9: NO), the control unit 100 does not need to provide route guidance to the parking lot, so the processing procedure is changed to step S1. return. In addition, when the destination is set (step S9: YES), the control unit 100 calculates the route to the parking lot set as the destination, and then, based on the calculation result, Guidance to the ground is started (step S10), and then the process is terminated. Thereby, the driver | operator etc. can move a vehicle smoothly to the parking lot around a vehicle.

  As described above, according to the navigation device 1 of the present embodiment, when the map is displayed in the map display area MA and the TV video in the TV video display area TA is in a non-display state, When the touch panel 32 is touch-operated, since the parking lots around the vehicle are searched, the driver and the like can easily and quickly search the surrounding parking lots when the TV image is desired. Thus, the vehicle can be parked in a desired nearby parking lot and the TV can be watched slowly.

  Further, according to the navigation device 1 of the present embodiment, when the TV image display area TA is touch-operated on the surface of the touch panel 32, a parking lot search is performed to search for a parking lot around the vehicle. The driver or the like can specify the location of the parking lot search button 33 without explicitly indicating the parking lot search button 33 by display or the like.

  Further, according to the navigation device 1 of the present embodiment, since the parking lot obtained as a result of the search is displayed in the TV video display area TA, the visibility of the map is not lowered. In addition, by clearly indicating the location of the parking lot obtained as a result of the search on the map, the driver can grasp the location of the parking lot and the positional relationship between the current position and the parking lot.

  Further, according to the navigation device 1 of the present embodiment, since the parking lots are displayed in the TV image display area TA in the order from the own vehicle position, the driver or the like can find the nearest parking lot (the earliest arrival). Easy to choose.

  In addition, according to the navigation device 1 of the present embodiment, the display form of the search result is changed according to the size of the TV video display area TA, so the visibility is improved in consideration of the size of the TV video display area TA. Search results can be displayed in an excellent manner. For example, when the size of the TV image display area TA is narrower than a predetermined size, the display mode is simplified such that the parking lot obtained as a result of the search is displayed by an identification number. Thus, the visibility of the search result can be improved.

  Note that the above-described embodiment merely shows one aspect of the present invention, and can be arbitrarily modified within the scope of the present invention. For example, in the above-described embodiment, a two-screen display that displays a map and a TV image at the same time has been described.
