As shown in FIG. 1, the navigation device 1 includes a position signal receiving device 11, an autonomous navigation device 12, a traffic information signal receiving device 13, an external storage device 2, an input device 3, a clock 14, and arithmetic processing. The unit 4 includes a drawing unit 5, a display unit 6, and the like.

  The position signal receiving device 11 receives GPS (Global Positioning System) signals transmitted from artificial satellites such as at least three NAVSTAR (NAVigation System using Timing And Ranging), and outputs them to the arithmetic processing unit 4. The GPS signal is used by the arithmetic processing unit 4 to calculate the coordinates of the current location.

  The autonomous navigation device 12 includes an angle sensor, a distance sensor, and the like. The angle sensor detects the angular velocity of the vehicle (the rotation angle in the horizontal direction per unit time). A distance sensor detects the vehicle speed pulse signal output according to rotation of a wheel. These angular velocity signals and vehicle speed pulse signals are used by the arithmetic processing unit 4 to calculate the amount of change in the moving direction of the vehicle and the amount of movement of the vehicle.

The traffic information signal receiver 13 performs VICS (Vehicle Information and Communication System : registered trademark ) and other data communication, for example, and outputs the coordinates of the traffic information obtained by the communication to the arithmetic processing unit 4. Here, the traffic information includes, for example, traffic congestion on the road, traffic regulation, and the like.

  The external storage device 2 is an HDD, a DVD, or the like, and stores map information and POI information (Point of Interest; information on various facilities such as sightseeing spots) and a sun rise / fall time table 21. As shown in FIG. 2, the date and time table 21 stores the coordinates of the date and point (latitude and longitude), the sunrise time and the sunset time in association with each other. For example, the sunrise time on January 10th at a location of latitude 35 ° 40 ″ and longitude 138 ° 40 ″ is 6:08, and the sunset time is 17:50 in association with each other.

The input device 3 is a touch panel provided so as to cover the display unit 6, detects coordinates instructed by a coordinate reading principle such as an electromagnetic induction type, a magnetostrictive type, and a pressure sensitive type, and detects the detected coordinates as a position signal. Is output to the arithmetic processing unit 4 as follows. The input device 3 includes various keys associated with various functions such as navigation, in addition to character keys, numeric keys, and search keys, and outputs an operation signal for the operated key to the arithmetic processing unit 4. Also good. Or it is good also as a structure provided with input devices 3, such as a remote controller and a microphone.
The clock 14 generates current date time information and outputs it to the arithmetic processing unit 4.

  The arithmetic processing unit 4 includes a CPU, a main storage device, etc., calculates the current position coordinates from the GPS signal output from the position signal receiving device 11, and uses the angular velocity signal and the vehicle speed pulse signal output from the autonomous navigation device 12. Then, the moving direction and moving amount of the vehicle are calculated. In addition, the arithmetic processing unit 4 corrects the current position coordinates by performing map matching between the road information included in the map information of the external storage device 2 and the GPS signal.

  The main memory of the arithmetic processing unit 4 is a flash memory or the like. The program for driving the arithmetic processing unit 4, the coordinates of the departure place, the coordinates of the current position, the coordinates of the destination and waypoints, the coordinates of points on the passage route A color table 41 and a background color table 42 are stored.

  As shown in FIG. 3, the color table 41 is stored with a color code associated with a time. In FIG. 3, the color code is stored corresponding to the time every 5 minutes, but the interval is arbitrary. A method for creating the color table 41 will be described later.

  In the background color table 42, as shown in FIG. 4, the horizontal coordinates of the simple route display bar 7 described later are associated with the coordinates of the departure point, the destination and the waypoint, and the passing point on the route, It is also associated with the arrival (planned) time to each point, and further stored with the color code corresponding to the arrival (planned) time. A method for creating the background color table 42 will be described later.

Further, the arithmetic processing unit 4 uses the calculated current position coordinates, the coordinates of the destination or waypoint input by the input device 3, the moving direction of the vehicle, the moving amount, the map information, the road traffic information, etc. To calculate the total path length. Here, the route information includes the coordinates of the current location, the coordinates of the point between the departure point, the destination, and the waypoint, the coordinates of the point on the passing route, and the like.
The drawing unit 5 is controlled by the arithmetic processing unit 4, creates display image data to be displayed on the display unit 6 using the route information output from the arithmetic processing unit 4 and the map information of the external storage device 2, and displays the display image data. Output to unit 6.

  The display unit 6 is a color liquid crystal display or the like. The display unit 6 is controlled by the arithmetic processing unit 4 to display a map in which a route to a destination or waypoint is highlighted based on the display image data and a simple route display bar 7 to be described later.

  Here, an image displayed on the screen of the display unit 6 will be described. FIG. 5 is a diagram illustrating an example of an image displayed on the screen of the display unit 6. As shown in FIG. 5, a map 61 including a route is displayed on the entire screen of the display unit 6, and a simple route display bar 7 is displayed at the top of the screen.

  The pixels on the simple route display bar 7 correspond to the passing points on the route from the departure point to the destination created by the arithmetic processing unit 4. For example, if the pixels of the simple route display bar 7 are arranged in n columns in the left-right direction, the left end (first column) corresponds to the coordinates of the departure place, and the right end (n column) is the destination. Corresponding to the coordinates, columns 2 to (n-1) correspond to the coordinates of each passing point from the starting point to the destination.

  The simple path display bar 7 displays the color gradation in a stepwise manner in the left-right direction. The color of each column of pixels corresponds to the arrival time at the corresponding point, so that the arrival time at the destination can be visually grasped.

Here, a method of creating the color table 41 used for displaying the simple route display bar 7 will be described.
First, the arithmetic processing unit 4 reads “sunrise time” and “sunset time” from the sunken time table 21 from the current date and time and coordinates.

Next, the arithmetic processing unit 4 writes the darkest color code “ccc” in the “color code” of the row before the sunrise time and after the sunset time of the color table 41, and also displays the sunrise time and sunset time. The color code “aaa” of the brightest color is written in the “color code” in the row at the intermediate time (for example, 12:00). Also, in the “color code” from the sunrise time to the middle time, a color code is written so that the luminance continuously increases from the darkest color to the brightest color, and the “color code” from the middle time to the sunset time is written. In the “code”, a color code is written so that the luminance gradually decreases from the brightest color to the darkest color.
Thus, the color table 41 is created.

Next, a display method of the simple route display bar 7 will be described.
First, when the user operates the input device 3 to input a destination and instruct a route search, the arithmetic processing unit 4 displays “position coordinates” in a column corresponding to “bar coordinates” of “1” in the background color table 42. The coordinates of the departure place are written, and the coordinates of the arrival place are stored in the “position coordinates” of the column corresponding to the “bar coordinates” of “n”.

  The arithmetic processing unit 4 searches the route between the departure position and the set destination with reference to the map information, and the drawing unit 5 controlled by the arithmetic processing unit 4 is output from the arithmetic processing unit 4. Using the route information and the map information stored in the external storage device 2, the display image data of the map in which the route to the destination or the waypoint is highlighted is generated and output to the display unit 6.

  Next, the arithmetic processing unit 4 equally divides the searched route length into n, obtains the coordinates of the passing points that divide the route into n, and obtains “bar” of “2” to “n−1” of the background color table 42. In the “position coordinates” in the column corresponding to “coordinates”, the coordinates of the passing points that divide the route into n−1 equal parts in the order from the departure side to the destination are stored.

  Next, the arithmetic processing unit 4 calculates the arrival time at the destination and the point at which the route is equally divided into n, and the column corresponding to the “bar coordinates” of “1” to “n” in the background color table 42. Write in "Time".

  Next, the arithmetic processing unit 4 refers to the color table 41 and sets the color code corresponding to the time to “color code” in the column corresponding to “bar coordinates” of “1” to “n” of the background color table 42. Write to.

  Thereafter, the arithmetic processing unit 4 outputs color code information corresponding to each of the 1 to n columns of the simple route display bar 7 to the drawing unit 5. The drawing unit 5 displays each column of the simple route display bar 7 with the color specified by each color code based on the information of the color code. For example, the first column is displayed in the color specified by the color code “XXX”, the second column is displayed in the color specified by the color code “XXY”, and the k column is specified by the color code “XYZ”. The nth column is displayed in a color designated by the color code “ZZZ”.

  In this way, the pixels on the simple route display bar 7 corresponding to the passing point on the route from the departure point to the destination can be set to a color corresponding to the time of passage or arrival, and the user is scheduled to arrive. The time can be grasped visually.

In FIG. 5, the own vehicle icon 71 and the destination flag 72 are displayed on the simple route display bar 7.
The own vehicle icon 71 is displayed at the left end on the simple route display bar 7 at the time of departure. The destination flag 72 is displayed at the right end.

When the vehicle equipped with the navigation device 1 travels along the route, the position for displaying the vehicle icon 71 moves to the right as shown in FIG.
The position at which the vehicle icon 71 is displayed is calculated simply by calculating the ratio of the route from the vehicle position to the destination received and analyzed by the position signal receiving device 11 to the entire route in the arithmetic processing unit 4 and calculating the ratio. It is determined by calculating the vehicle position on the display bar. The drawing unit 5 draws the own vehicle icon 71 according to the determined own vehicle position.

In FIG. 6, the background color is different from that in FIG. This is because the progress of the vehicle equipped with the navigation device 1 is delayed from the schedule.
In other words, when the actual passage time is delayed from the scheduled time of passing through the current point, the arithmetic processing unit 4 recalculates the passing point after the current location and the scheduled time of arrival at the destination, and the background color table 42. Write in the "time".

  Next, the arithmetic processing unit 4 refers to the color table 41 and writes the color code corresponding to the corrected time in the “color code” of the background color table 42.

  Thereafter, the arithmetic processing unit 4 outputs information on the color code corresponding to each of the 0 to n columns of the simple route display bar 7 to the drawing unit 5. The drawing unit 5 displays the color corresponding to each color code in each column of the simple path display bar 7 based on the information of the color code.

  With the above operation, even if the vehicle on which the navigation device 1 is mounted is delayed, the user can visually grasp the estimated arrival time that has been delayed.

  In the above, the case where the progress is delayed from the scheduled time has been described, but the recalculation and display are similarly performed when the vehicle passes through the current location earlier than the scheduled time.

  FIG. 7 is a display example of the simple route display bar 7 when a traffic jam occurs on the route to the destination. In this case, a status icon 73 indicating traffic jam is displayed in the middle of the simple route display bar 7.

  The position at which the status icon 73 is displayed is obtained by calculating the ratio of the route from the traffic congestion or traffic regulation position to the destination to the destination in the arithmetic processing unit 4 received and analyzed by the traffic information signal receiving device 13. The traffic congestion position on the simple display bar is determined from the ratio. The drawing unit 5 draws the state icon 73 according to the determined traffic position.

  The user can grasp the cause of the delay in the vehicle travel by looking at the status icon 73 indicating traffic jam or traffic regulation.

  When the user's finger 8 taps the state icon 73 on the simple route display bar 7, the input device 3 detects the coordinates instructed to be touched, and outputs the detected coordinates to the arithmetic processing unit 4 as a position signal. When the arithmetic processing unit 4 detects from the position signal that the user has touched the position where the state icon 73 is displayed, the arithmetic processing unit 4 externally stores map information corresponding to the coordinates of the position of the traffic jam received and analyzed by the traffic information signal receiving device 13. Read from the device 2 and output to the drawing unit 5 together with the road traffic information. The drawing unit 5 creates display image data for displaying a map around a traffic jam position based on the input road traffic information and map information, and outputs the display image data to the display unit 6. The display unit 6 displays a map around the traffic jam position based on the input display image data.

  Thus, the user can grasp the situation around the traffic jam position by tapping the state icon 73 on the simple route display bar 7, and can search for a detour route.

  FIG. 8 is a display example of the simple route display bar 7 when there are various facilities such as sightseeing spots in the middle of the route to the destination. In this case, a POI icon 74 is displayed in the middle of the simple route display bar 7.

  The position at which the POI icon 74 is displayed is the position of the route from the location of various facilities such as tourist spots obtained by referring to the POI information stored in the external storage device 2 to the destination in the arithmetic processing unit 4 for all routes. The ratio is calculated, and the POI position on the simple display bar is determined from the obtained ratio. The drawing unit 5 draws the POI icon 74 according to the determined POI position.

  By looking at the background color of the POI icon 74, the user can visually grasp the scheduled time of arrival at various facilities such as a sightseeing spot along the route.

  When the user taps the POI icon 74 on the simple route display bar 7, the input device 3 detects the coordinates instructed to be touched, and outputs the detected coordinates to the arithmetic processing unit 4 as a position signal. When it is detected from the position signal that the user has touched the position where the POI icon 74 is displayed, the arithmetic processing unit 4 reads the POI information and the corresponding map information from the external storage device 2 and outputs them to the drawing unit 5. Based on the input POI information and map information, the drawing unit 5 creates display image data for displaying a map around various facilities such as sightseeing spots and outputs the display image data to the display unit 6. The display unit 6 displays a map around various facilities such as sightseeing spots based on the input display image data.

  Thus, the user can grasp the situation around various facilities such as a sightseeing spot by tapping the POI icon 74 on the simple route display bar 7.

  FIG. 9 is a display example of the display unit 6 when an arbitrary position on the route is displayed. In this case, a display position icon 75 indicating the relative position on the route of the currently displayed map is displayed in the middle of the simple route display bar 7. The position where the display position icon 75 is displayed on the simple route display bar 7 varies according to the scrolling operation of the map.

  The position where the display position icon 75 is displayed is calculated by calculating the ratio of the route from the position of the map displayed on the display unit 6 to the destination in the arithmetic processing unit 4 with respect to all the routes, and from the obtained ratio, a simple display bar. Determine the top display position. The drawing unit 5 outputs display image data for displaying the display position icon 75 to the display unit 6 according to the determined display position. The display unit 6 displays a display position icon 75 based on the input display image data.

  When the user's finger 8 taps an arbitrary point on the simple route display bar 7, the input device 3 detects the touched coordinate and outputs the detected coordinate to the arithmetic processing unit 4 as a position signal. The arithmetic processing unit 4 calculates “bar coordinates” corresponding to the position touched by the user on the simple route display bar 7 based on the position signal, and refers to the background color table 42 to correspond to “position coordinates”. "Coordinates" are obtained and output to the drawing unit 5. The drawing unit 5 displays the display position icon 75 at the point touched by the user on the simple route display bar 7 based on the input position coordinates, and creates display image data for displaying a map around the corresponding coordinates. And output to the display unit 6. Based on the input display image data, the display unit 6 displays a display position icon 75 at a point touched by the user on the simple route display bar 7 and displays a map around the corresponding coordinates.

  A recording folder for recording the coordinates of the position displayed on the map may be provided in the external storage device 2, and a recording folder icon 62 indicating the recording folder may be displayed on the display unit 6.

  As shown in FIG. 10, when the user drags the display position icon 75 onto the recording folder icon 62, the input device 3 detects that the display position icon 75 is dragged onto the recording folder icon 62, and calculates it as a position signal. Output to the processing unit 4. The arithmetic processing unit 4 to which the position signal is input stores the map information for displaying the position corresponding to the display position icon 75 in the recording folder of the external storage device 2.

  When the user taps the recording folder icon 62, the input device 3 detects the coordinates instructed to be touched, and outputs the detected coordinates to the arithmetic processing unit 4 as a position signal. When the arithmetic processing unit 4 detects that the recording folder icon 62 is tapped by the position signal, the arithmetic processing unit 4 creates a list of positions displayed in the map information stored in the recording folder of the external storage device 2. To the drawing unit 5. The drawing unit 5 creates display image data for displaying the position list based on the input information, and outputs the display image data to the display unit 6.
