The ROM 3 is a semiconductor storage device that stores a program executed by the CPU 2. The RAM 4 is a semiconductor memory device that stores various data in a readable and writable manner.

  The HDD 5 stores programs executed by the CPU 2 and also stores map information (map display data, road link data, etc.). The video circuit 6 is a circuit that executes display processing according to the display command supplied from the CPU 2, converts an image obtained as a result of the display processing into a video signal, and outputs the video signal to the liquid crystal display device 8.

  The I / F 9 converts and inputs the representation format of signals output from the touch panel 10, the input unit 11, the sensor 12, and the GPS device 13, and converts the representation format of signals output to the audio output device 14. To do. The bus 7 is a signal line group for connecting the CPU 2, ROM 3, RAM 4, HDD 5, video circuit 6, and I / F 9 to each other and enabling exchange of information among them.

  The liquid crystal display device 8 constitutes display means for displaying the video signal output from the video circuit 6 on a liquid crystal screen. As the display means, in addition to the liquid crystal display device 8, an organic EL display, a CRT display, a plasma display, or the like can be used.

  The touch panel 10 is arranged on the screen of the liquid crystal display device 8 so as to detect a touched position as a coordinate position (instructed position) on the screen, and information on the coordinate position is used as an operation signal I. It has a function of outputting to the CPU 2 via / F9, and is an example of a position detection means. The input unit 11 includes buttons, switches, and the like, and has a function of generating an operation signal based on information according to an operation by the operator and outputting the operation signal to the CPU 2 via the I / F 9.

  The sensor 12 includes a vehicle speed sensor that detects the speed of the vehicle, an angular speed sensor that detects the angular speed of each control axis of the vehicle, a steering angle sensor that detects the steering angle of the steering wheel, and the like. The GPS device 13 is a device that obtains the current position (latitude, longitude, altitude) of the vehicle using information transmitted from a plurality of GPS artificial satellites, and sends this to the CPU 2. The audio output device 14 is a device that performs D / A (Digital to Analog) conversion on data supplied from the CPU 2 and outputs the data as audio.

  Next, the display operation of the navigation screen of the navigation device 1 will be described with reference to FIGS. FIG. 2 is a flowchart showing a processing operation for displaying the navigation screen shown in FIGS. 3 to 7 on the liquid crystal display device 8, for example.

  Each step of the flowchart shown in FIG. 2 is realized by the CPU 2 executing a navigation program.

  First, when an instruction for destination setting is given from the input unit 11 by the operator, the CPU 2 displays a map display screen 15 as shown in FIG. 3 on the liquid crystal display device 8 as a navigation screen (step S10). The map display screen 15 is an image of a map on which a car 16 that is the car (vehicle) on which the navigation device 1 is mounted, a road line (road link) 17 around the car 16, and the like are drawn. Are displayed at a scale set by the input unit 11.

  The display of the map display screen 15 (step S10) is specifically realized as follows by the CPU 2 as the map display means. First, the CPU 2 detects the current position of the host vehicle 16 based on data acquired from the sensor 12 and the GPS device 13. Subsequently, based on the current position of the host vehicle 16, the surrounding map 18 where the host vehicle 16 is located is acquired from the map information stored in the HDD 5. Then, map matching between the surrounding map 18 and the position of the vehicle 16 is performed, and the video display 6 is controlled by controlling the video circuit 6 on the map display screen 15 which is an image of the vehicle 16 on the surrounding map 18. 8 is displayed on the screen.

  In a state where the map display screen 15 is displayed on the liquid crystal display device 8, the CPU 2 as the scroll control means waits for a scroll display instruction (step S20). This scroll display instruction can be made by touching (touching) the touch panel 10. The CPU 2 is configured to scroll the map in the direction of the touch position viewed from the center of the touch panel 10, that is, the center of the map display screen 15 (position where the touch panel 10 is touched / pressed with a finger).

  In other words, when the operator touches the center of the map display screen 15 with the finger in the direction in which the surrounding map 18 displayed as the map display screen 15 is to be scrolled, the screen is superimposed on the screen of the liquid crystal display device 8. A signal indicating the coordinates of the touch position is output from the touch panel 10 that is arranged. Based on this signal, the CPU 2 scrolls the peripheral map 18 in the direction of the touch position viewed from the center of the map display screen 15.

  When the operator instructs the navigation device 1 to perform scroll display by touching the map display screen 15, that is, the touch panel 10 with a finger (Yes in Step 20), the navigation device 1 is displayed as the map display screen 15. The low-speed scroll display for scrolling and displaying the surrounding map 18 at low speed is started (step S30). Then, the CPU 2 continues the low-speed scroll display while the finger is touched on the touch panel 10, and stops the low-speed scroll display when the finger is released from the touch panel 10. When a finger is touched on the touch panel 10, the CPU 2 as the index display means displays a cross arrow 19 superimposed on the scroll-displayed map 18A as shown in FIG. In addition to the cross arrow 19, the CPU 2 has a function of performing various displays for prompting the operation of the navigation device 1 on the map display screen 15 in addition to the cross arrow 19.

  The CPU 2 determines an elapsed time after the scroll display is started, that is, after the finger touches the touch panel 10 (step S40). Then, when it is determined that a predetermined time (for example, 2 seconds) has elapsed after the scroll display is started, that is, when it is determined that 2 seconds have not elapsed since the scroll display was started (in step S40). No), the map 18A displayed on the map display screen 15 is scroll-displayed at a low speed (step S30).

  Specifically, the speed of the low-speed scroll display is a speed at which the operator can visually recognize the place name or the like written on the map 18A being scroll-displayed. Thus, by performing the low-speed scroll display for a predetermined time after the scroll display is started, the operator can easily recognize the display content of the map 18A.

  On the other hand, if the CPU 2 determines that two seconds or more have elapsed since the finger was touched on the touch panel 10, that is, two seconds or more have elapsed since the scroll display was started (Yes in step S40). Then, high-speed scroll display (high-speed scroll display) is started (step S50). Note that the predetermined time from when the finger touches the touch panel 10 until the high-speed scroll display is started is not limited to the above-described two seconds, but considering the ease of recognition of the display content of the map 18A by the operator. Above, it is preferable to set to an appropriate time.

  When the high-speed scroll display is executed (step S50), the display of the cross arrow 19 shown in the map display screen 15 of FIG. 4 is erased. Instead, the CPU 2 as the button display means is shown in FIG. In this way, the scroll continuation button 20 for instructing continuation of the high speed scroll display on the map 18B displayed at high speed scroll, and the destination list display button 21 which is a destination setting button for setting the destination and the POI. (Point of Interest) The input screen display button 26 is displayed (step S60). The scroll continuation button 20, the destination list display button 21, and the POI input screen display button 22 are preferably displayed in a semi-transparent state so that the map 18B behind can be confirmed. The scroll continuation button 20, the destination list display button 21, and the POI input screen display button 26 are displayed after a predetermined time (for example, 2 seconds) has elapsed since the high-speed scroll display (step S50) is performed. You may do it.

  When the position where the scroll continuation button 20, the destination list display button 21, and the POI input screen display button 22 are displayed is touched on the screen, a signal at a coordinate position corresponding to the position of each button is output from the touch panel 10. It is sent to the CPU 2 via F9. Upon receiving this signal, the CPU 2 performs control corresponding to each button.

  As described above, the scroll continuation button 20 is a button for instructing the CPU 2 to continue the high-speed scroll display. The CPU 2 displays the scroll continuation button 20 at a position where a finger is touching the touch panel 10 for scroll display. That is, the scroll continuation button 20 is displayed at a location where the touch panel 10 is touched for 2 seconds or more. Therefore, in the state where high-speed scrolling is started, the finger is pressing (touching) the scroll continuation button 20. Therefore, the operator can recognize that the scroll display is continued.

  The CPU 2 determines that the high-speed scroll display is instructed while the scroll continue button 20 is pressed (Yes in step S70), continues the high-speed scroll display (step S50), and continues the scroll continue button 20, the purpose. The display of the land list display button 21 and the POI input screen display button 22 is continued (step S60). On the other hand, when the finger is released from the scroll continuation button 20 and the scroll continuation button 20 is not touched (No in step S70), the CPU 2 stops the scroll display and displays a map of the position where the scroll display is stopped ( Step S80). Even in this state, the CPU 2 continuously displays the scroll continuation button 20, the destination list display button 21, and the POI input screen display button 22 in conjunction with the display of the map in the stopped state (step S80).

  When the destination list display button 21 is pressed in the display state in step S80 (Yes in step S90), that is, the operator touches the portion of the touch panel 10 where the destination list display button 21 is displayed. In this case, as shown in FIG. 6, the CPU 2 as the button display means displays a list 23 of destinations that have been selected as destinations in the past (step S100). This list 23 is displayed together with a map 18C at a position where the CPU 2 stops scrolling display.

  The destination displayed in the list 23 is recorded in the HDD 5 as a destination that has been selected as a destination in the past, and follows the scroll direction from the position of the map 18C displayed on the screen. Are displayed in the order in which they are directed in the scroll direction. When the destination displayed in the list 23 is touched, the CPU 2 calculates a guidance route from the position of the host vehicle 16 to the touched destination, and guides the host vehicle 16 to the destination on the map. Display the guidance route. As described above, the destinations displayed in the list 23 are displayed in the order according to the scroll direction, so that the destination can be easily searched.

  Also, when the POI input screen display button 22 is pressed (Yes in step S110), that is, when the operator touches a portion of the touch panel 10 where the POI input screen display button 22 is displayed, it is shown in FIG. Thus, CPU2 which is a button display means displays the POI search screen 24 (step S120). The POI search screen 24 is also displayed together with the map 18C at the position where the CPU 2 stopped scrolling. When a destination building name, address, or the like is input as a search condition on the POI search screen 24, a map including a position corresponding to the search condition is read from the HDD 5 to the CPU 2 and displayed on the liquid crystal display device 8. Further, the CPU 2 calculates a guide route from the position of the host vehicle 16 to the searched destination, and displays a guide route for guiding the host vehicle 16 to the destination on a map.

  As the POI search screen 24, a selection menu for each genre such as a facility, a store, and a restaurant is displayed. When a desired genre position is touched from this selection menu, a list of destinations corresponding to the touched genre is displayed. You may be made to do. In this case, when a desired destination in the list of destinations is touched, the CPU 2 calculates a guide route from the position of the host vehicle 16 to the touched destination, and places the host vehicle 16 on the map. A guidance route for guiding to this destination will be displayed.

  In addition, in order to press the destination list display button 21 or the POI input screen display button 22, the finger is once released from the scroll continuation button 20, but if you change your mind and want to resume the high-speed scroll display again, When the scroll continuation button 20 is pressed (Yes in step S130), the high-speed scroll display is resumed (step S50). Even if the finger is released from the scroll continuation button 20, the scroll continuation button 20 remains displayed, and when the scroll continuation button 20 is pressed, the high-speed scroll display is resumed, so that the high-speed scroll display is immediately resumed. Can start.

  On the other hand, when it is desired to scroll the map around the map displayed on the map display screen 15, as in step S20, the position in the direction to be scrolled as viewed from the center of the screen is touched (step S140). Yes). Thereby, the CPU 2 turns off the display of the scroll continuation button 20, the destination list display button 21, and the POI input screen display button 22 (step S150), and starts low-speed scrolling in the touched direction (step S30). Note that if the scroll continuation button 20, the destination list display button 21, the POI input screen display button 22 is not pressed or the low speed scroll is not started (No in step S140), the display in step S80 is continued.

  Note that the position where the touch panel 10 is touched for scroll display varies depending on the scrolling direction. Therefore, the display position of the scroll continuation button 20 is also different. Therefore, the CPU 2 preferably displays the destination list display button 21 and the POI input screen display button 22 at positions that do not overlap the scroll continuation button 20.

  As described above, the destination list display button 21 and the POI input screen display button 22 are displayed together with the scroll display, so that it is difficult to search for the destination by the scroll display. It is possible to easily shift to a search using the POI input screen display button 22. Further, since the scroll continuation button 20 is also displayed together with the destination list display button 21 and the POI input screen display button 22, the search by the destination list display button 21 and the POI input screen display button 22 and the search by the scroll display are performed. It can be selected appropriately.

(Modification 1)
Next, a modification of the above embodiment will be described.

  As a mode in which the navigation device 1 is used, for example, it is possible to use the route service for circulating fixed customers. In such a usage mode, the operator often stores the destination in the HDD 5 in advance, and the destination can often be easily searched. Therefore, it is considered that the purpose of scroll display in such a usage mode is mainly to search around the destination, such as searching for a parking lot around the searched destination. That is, the necessity of displaying the destination list display button 21 and the POI input screen display button 22 is considered to be low. Assuming such usage, even if the navigation device 1 is displayed in a high-speed scroll display, the button that does not display the scroll continuation button 20, the destination list display button 21, and the POI input screen display button 22 is not displayed. It is good also as a structure which can be preset so that it may become.

  When such a configuration is adopted and button non-display is set, the navigation screen is displayed according to the flowchart shown in FIG. In the flowchart shown in FIG. 8, the same step numbers are assigned to the same processes as those in the flowchart shown in FIG. 2, and the description thereof is omitted.

  If button non-display is set, it is determined whether or not to continue the high-speed scroll display while the high-speed scroll display is being performed (step S50). This determination is made as to whether or not the touch for starting the scroll display is continuously performed. Therefore, if the touch remains (Yes in step S160), the high-speed scroll display (step S50) is continued, and if the finger leaves the touch panel 10 and the touch is no longer performed (No in step S160). ), The scroll display is stopped (step S170), and the map at the position where the scroll display is stopped is displayed (step S10). On the other hand, when the button non-display setting is not performed, the above-described flowchart of FIG. 2 is executed.

  In the embodiment and the modification described above, an example in which the navigation device 1 is operated by the touch panel 10 has been described. However, instead of directly touching (touching) the touch panel 10 with a finger, the navigation apparatus 1 may be operated by a remote controller. Also good. In this case, for example, when a cross key on the remote controller is pressed, a low-speed scroll display is started according to the pressing direction of the cross key. Then, when the low-speed scroll display is continued for a predetermined time (for example, 2 seconds), the display changes to the high-speed scroll display, and the scroll continue button 20, the destination list display button 21, and the POI input screen display button 22 are displayed on the screen. The At this stage, once the pressing of the cross key is released, the high-speed scroll display stops. Each time the cross key is pressed again, the scroll continuation button 20, the destination list display button 21, and the POI input screen display button 22 are traced in order, and operations corresponding to the buttons can be performed from the remote controller.

  Next, a navigation device 31 according to another embodiment of the above-described navigation device 1 will be described with reference to FIGS. 9 to 12.

  The navigation device 1 according to the above-described embodiment displays the destination list display button 21 and the POI input screen display button 22 so that the destination search can be easily performed during the high-speed scroll display. And the transition to the destination search operation can be easily performed.

  On the other hand, the navigation device 31 reduces the scale of the map that is scroll-displayed while performing low-speed scroll display, and scrolls and displays the map in this state for a short time. Is displayed on the screen. When the destination is displayed on the map displayed on the screen or when the map is scrolled to the vicinity of the destination, the scale of the map is enlarged and the surrounding map including the enlarged destination is displayed. It is comprised as follows. Therefore, when the operator knows the approximate position of the destination, the destination can be searched quickly.

  FIG. 9 shows the configuration of the navigation device 31. The navigation device 31 has the same configuration as the navigation device 1 except that the CPU 2 has a function as a scale changing means. Therefore, about the structure similar to the navigation apparatus 1, the same code | symbol is described and the description is abbreviate | omitted. The navigation device 31 performs an operation based on the process shown in FIG. Each step of the flowchart shown in FIG. 10 is realized by the CPU 2 executing a navigation program.

  First, when a destination setting instruction is given from the input unit 11 by the operator, a map display screen 33 as shown in FIG. 11 is displayed on the liquid crystal display device 8 as a navigation screen (step S200). The map display screen 33 displays the map 18 on which the host vehicle 16 and the road lines (road links) 17 around the host vehicle 16 are drawn at a scale set by the input unit 11. It is. The map display screen 33 in step S200 is the same as the map display screen 15 in step S10 in the flowchart of FIG.

  In a state where the map display screen 15 is displayed on the liquid crystal display device 8, the operator wants to scroll the map 18 displayed as the map display screen 33 with respect to the center of the map display screen 33. When the position is touched with a finger, the CPU 2 as the scroll control means scrolls and displays the map 18 at a low speed in the direction of the touch position viewed from the center of the map display screen 33 based on the touch signal.

  Thus, when the operator instructs the navigation device 1 to perform scroll display by touching the map display screen 33, that is, the touch panel 10 with a finger (Yes in step 210), the navigation device 31 displays the map. The map 18 displayed on the screen 33 is scroll-displayed at a low speed (step S220). The CPU 2 continues this low-speed scroll display while the finger is touched on the touch panel 10. When the touch panel 10 is touched with a finger, the CPU 2 serving as the index display unit overlaps the scroll-displayed map 18A as shown in FIG. 12, and a double arrow for instructing a scale change to be described later. 34 is displayed. This double arrow 34 is displayed above the position where the finger is touched.

  When there is an instruction to change the scale of the scrolled map (Yes in step S230) during the scroll display (step S220), the CPU 2 as the scale changing means follows the instruction. The scale of the scrolled map 18A is changed (step S240). By moving the finger touched for scroll display along the direction of the double arrow 34, the scale of the map 18A being scrolled is changed according to the direction and amount of movement. When the finger touched for scroll display is moved along the direction of the double arrow 34, the signal indicating the coordinate position of the touch position output from the touch panel 10 changes. A coordinate position signal related to the direction and amount of change of the touch position is input to the CPU 2 via the I / F 9. The CPU 2 changes the scale of the map 18A that is scroll-displayed based on the coordinate position signal.

  For example, when the touch position of a finger is slid in the “+” (plus) direction of the double arrow 34, the scale of the map 18A increases (the display area of the map 18A decreases). Conversely, if the touch position of the finger is slid in the “−” (minus) direction, the scale of the map 18A becomes smaller (the display area of the map 18A becomes wider). Therefore, while scrolling the display (while keeping the finger touching the screen), the touch position is slid in the direction of “-”, and the scale of the scroll-displayed map 18A is reduced, so that the destination at a long distance is displayed. Display on the screen in a short time. At this time, since the map 18A is scroll-displayed at a low speed, the operator can perform scroll-display while confirming the display content of the map 18A.

  When the destination is displayed on the map displayed on the map display screen 33, this time, the touch position is slid in the direction of “+”, and the scale of the scrolled map is enlarged to enlarge. A surrounding map including the destination is displayed. When the map is displayed at an appropriate magnification, the scroll display is stopped by releasing the finger from the screen (No in step S210), and the map at the position where the scroll display is stopped instead of the scroll display (step S220). Is displayed (step S200).

  When a destination on the map is selected, the CPU 2 calculates a guidance route from the position of the vehicle 16 to the selected destination, and guides the vehicle 16 to the destination on the map. Display the route.

  In the navigation device 31 described above, when the finger is slid beyond the length of the double arrow 34, or when the finger is slid in a direction perpendicular to the double arrow 34, the scroll direction of the map 18 is set in the slid direction. You may comprise so that it may change.

  In addition, the navigation apparatuses 1 and 31 described above may be mounted on a mobile phone or the like, or configured to be portable by an operator, in addition to being used for mounting on a vehicle.
