As one of the sub power supply circuits, a map DB (abbreviation of database) power supply block (not shown) for the map database 112 is preferably provided. The map DB power supply block is provided on a power supply line connecting the battery 110 and the map database 112.

  The map DB power supply block preferably includes a voltage conversion device (voltage stabilization circuit) and the like. The map DB power supply block is preferably connected to the battery 110 via an ignition switch (not shown).

  The main processing unit 102 outputs a command (for example, a map DB power supply stop command or a map DB power supply command) to the main power supply block 108 (map DB power supply block), thereby supplying power to the map database 112. Is preferably controlled.

  A map database 112 is connected to the main arithmetic unit 102. The map database 112 has a relatively large memory (for example, several tens of Gbytes) such as a hard disk drive, CD, DVD, BD (Blu-ray Disc).

  The map database 112 stores given map data. The type of map data is arbitrary. The map data includes the coordinate information of each node corresponding to the junction / branch point of the intersection / highway, link information connecting adjacent nodes, road width information corresponding to each link, lane information, each link It is preferable that road information such as information indicating a road type such as a corresponding national road / prefectural road / highway is included.

  Moreover, it is preferable that the map data includes facility information regarding the types and positions of various facilities such as convenience stores, restaurants, parking lots, and fueling facilities. The map data is preferably updated regularly or irregularly based on update information from the outside (for example, a server of an information providing center).

  The main processing unit 102 accesses the map database 112 when the map display needs to be changed due to various operations such as a scroll operation or a scale change operation by a user's flick, or movement of the vehicle. Map data is read from the map database 112 and acquired. The main processing unit 102 generates (changes) a map display using the map data read from the map database 112 in this way. In addition, the vehicle position display may be superimposed on the map display. The own vehicle position display is preferably generated based on own vehicle position information obtained from a GPS receiver 114 described later.

  A video display device 104 is connected to the main processing unit 102. It is preferable that the video display device 104 is provided in a place where the driver in the vehicle cabin can easily see. The video display device 104 is preferably a touch panel. For example, a capacitive touch panel or a resistance pressure-sensitive touch panel can be applied. The video display device 104 may be configured as a display in a meter or a HUD (head-up display).

<Function of Navigation Device 100>
An example of the function of the navigation device 100 will be described.

  FIG. 2 is a functional block diagram showing an embodiment of the navigation device 100. The functions shown in this functional block diagram are mainly executed by the main arithmetic unit 102. The main processing unit 102 executes the functions shown in FIG. 2 according to an application (program) stored in the storage device 116.

  The main arithmetic unit 102 functions as a main control unit 202, an input processing unit 204, a route search processing unit 206, a sensitivity adjustment unit 208, and an output processing unit 210. The main control unit 202, the input processing unit 204, the route search processing unit 206, the sensitivity adjustment unit 208, and the output processing unit 210 are connected to each other.

  The main control unit 202 controls other functional blocks according to the processing content. The main control unit 202 acquires map information from the map database 112 and inputs it to the output processing unit 210. The main control unit 202 identifies the current position based on information from the GPS receiver 114 or the like. The main control unit 202 preferably performs control so that the current position is superimposed on the map information from the map database 112 and displayed on the video display device 104. Further, when a route search request is input from the input processing unit 204, the main control unit 202 requests the route search processing unit 206 to perform a route search. Further, the route search result from the route search processing unit 206 is input to the sensitivity adjustment unit 208 and the output processing unit 210.

  The input processing unit 204 inputs a route search request input from the user interface 106 to the main control unit 202. The input processing unit 204 inputs a flick input from the user interface 106 to the output processing unit 210. For example, the position information touched by the touch operation at the time of flick input is input from the user interface 106 to the input processing unit 204. The input processing unit 204 inputs position information from the user interface 106 to the output processing unit 210.

  The sensitivity adjustment unit 208 adjusts the sensitivity of the flick input from the user interface 106 based on the result of the guidance route search from the main control unit 202.

  FIG. 3 shows an example of processing of the sensitivity adjustment unit 208. FIG. 3 shows an example of map information displayed on the video display device 104. FIG. 3 shows a route from the departure point (current position) to the destination.

  As a result of the guidance route search, route information from the departure point “A” to the destination “B” is input from the main control unit 202. The sensitivity adjustment unit 208 adjusts the flick sensitivity in the direction from the starting point “A” (current location) to the destination “B” and the flick sensitivity in other directions so as to be different. For example, in the example shown in FIG. 3, the destination “B” on the display of the video display device 104 is upward as viewed from the departure point “A”. The sensitivity adjustment unit 208 adjusts the flick sensitivity in the vertical direction to be higher than the flick sensitivity in the horizontal direction. In FIG. 3, the sensitivity is indicated by the thickness of the arrow. The thicker the arrow, the higher the sensitivity, and the thinner the arrow, the lower the sensitivity.

  During driving, it is preferable that information in the vicinity of the route to the destination can be acquired by following the user's flick input. Therefore, the flick sensitivity in the direction substantially the same as the guidance path is increased. Further, in a direction different from the guidance route, it is not preferable that completely different map information is displayed as a result of scrolling by the user's flick input. Therefore, the flick sensitivity in a direction different from the guidance path is lowered.

  By increasing the flick sensitivity in the same direction as the guide route and lowering the flick sensitivity in a direction different from the guide route, if flick input is made in the same direction as the guide route, it will scroll at a high speed and guide When a flick input is made in a direction different from the direction, scrolling is performed at a low speed. For this reason, the feeling in a flick operation can be improved with respect to a user.

  Further, the sensitivity adjustment unit 208 adjusts the gain in the flick input in the direction from the departure point “A” (current location) to the destination “B” and the gain in the flick input in the other direction so as to be different. May be. For example, in the example shown in FIG. 3, the destination “B” is upward as viewed from the departure point “A”. The sensitivity adjustment unit 208 adjusts the gain in the vertical flick input to be higher than the gain in the horizontal flick input.

  By increasing the gain in the flick input in the same direction as the guide route and decreasing the gain in the flick input in a direction different from the guide route, when flick input is performed in the same direction as the guide route, the speed is high. If scrolling is performed and a flick input is made in a direction different from the guiding direction, scrolling is performed at a low speed. For this reason, the feeling in a flick operation can be improved with respect to a user.

  In addition, when flick input is performed in an oblique direction with respect to the guide route by increasing the gain in the flick input in the same direction as the guide route and decreasing the gain in the flick input in a direction different from the guide route, It is preferable that scrolling is performed based on a gain in a flick input in a direction substantially the same as the guide path and a gain in a flick input in a direction different from the guide path. By doing in this way, the feeling in a flick operation can be improved with respect to a user.

  The output processing unit 210 converts the map information from the main control unit 202 into a signal for drawing on the video display device 104 and inputs the signal to the video display device 104. The output processing unit 210 converts information on the current position from the main control unit 202 into a signal for drawing on the video display device 104 and inputs the signal to the video display device 104. The video display device 104 displays the current position superimposed on the map information.

  Further, the output processing unit 210 executes a process of scrolling the screen displayed on the video display device 104 according to the flick input from the input processing unit 204 based on the flick sensitivity set by the sensitivity adjustment unit 208.

  In addition, in order to make an understanding of the structure of the navigation apparatus 100 easy, each above-mentioned component is classified according to the main processing content. Therefore, it is not limited by the way of classifying the components or their names. The configuration of the navigation device 100 can be classified into more components depending on the processing content. Moreover, it can also classify | categorize so that one component may perform more processes.

  Each functional unit may be constructed by hardware (ASIC (Application Specific Integrated Circuit), GPU (Graphics Processing Unit), etc.). Further, it may be executed by hardware hardware of each functional unit, or may be executed by a plurality of hardware.

<Operation of Navigation Device 100>
FIG. 4 shows an example of the operation of the navigation device 100. The operation shown in FIG. 4 is mainly executed by the main arithmetic unit 102.

  In step S402, the destination is set in the navigation device 100. Destination information set by the user is input from the user interface 106 to the main arithmetic unit 102. The input processing unit 204 inputs destination information to the main control unit 202.

  In step S404, the navigation device 100 displays the guidance route. The route search processing unit 206 executes a route search in response to a guidance route search request from the main control unit 202. The route search processing unit 206 inputs a route search result to the main control unit 202. The main control unit 202 inputs a route search result to the sensitivity adjustment unit 208 and the output processing unit 210. The output processing unit 210 displays the guidance route on the video display device 104.

  In step S406, the navigation apparatus 100 adjusts the direction recognition sensitivity in the flick operation according to the information on the guidance route. The sensitivity adjustment unit 208 adjusts the flick sensitivity in the direction from the departure point (current location) to the destination and the flick sensitivity in other directions differently according to the route search result from the main control unit 202. For example, the sensitivity adjustment unit 208 adjusts the flick sensitivity in the direction from the starting point to the destination so as to be higher than the flick sensitivity in the direction orthogonal to the direction.

  In step S408, the navigation device 100 determines whether or not an operation for switching from the map display has been performed. The user can switch the display content of the video display device 104 from the map information to another content by operating the user interface 106. When the user performs an operation of switching the display content from the map information to another content, the operation content is input from the user interface 106 to the input processing unit 204. When the operation content for switching from the map display to another content is input from the input processing unit 204, the main control unit 202 inputs an instruction to switch the display content to the output processing unit 210. The output processing unit 210 switches the display content to another content in accordance with a command for switching the display content from the main control unit 202.

  In step S410, when it is determined in step S408 that the operation for switching from the map display has been performed, the navigation apparatus 100 returns the flick sensitivity to the initial value. When the operation content for switching from the map display to another content is input from the input processing unit 204, the main control unit 202 inputs a command for returning the flick sensitivity to the initial value to the sensitivity adjustment unit 208. The sensitivity adjustment unit 208 returns the flick sensitivity to the initial value in accordance with a command from the main control unit 202 to return the flick sensitivity to the initial value. As a result, the flick sensitivity in the direction from the departure point (current location) to the destination and the flick sensitivity in other directions are set to the same value.

  In step S412, the navigation apparatus 100 determines whether an operation for switching to map display has been performed. The user can switch the display content of the video display device 104 to map information by operating the user interface 106. When the user performs an operation of switching display content to map information, the operation content is input from the user interface 106 to the input processing unit 204. When the operation content for switching to the map display is input from the input processing unit 204, the main control unit 202 inputs a command for switching the display content to the output processing unit 210. The output processing unit 210 switches display contents according to a command to switch display contents from the main control unit 202.

  When the operation for switching to the map information is not executed, the process returns to step S410.

  If an operation for switching to map information is executed, the process returns to step S404.

  In step S414, when it is determined in step S408 that the operation for switching from the map display to another content is not performed, the flick operation is performed on the map display.

  In step S416, the navigation apparatus 100 scrolls the display screen according to the flick operation. The flick input is input from the user interface 106 to the output processing unit 210 via the input processing unit 204. The output processing unit 210 scrolls the display screen of the video display device 104 according to the flick input from the input processing unit 204.

  In step S418, the navigation apparatus 100 determines whether or not the destination has been reached. The main control unit 202 determines whether or not the destination has been reached.

  In step S420, if it is determined in step S418 that the vehicle has arrived at the destination, navigation device 100 returns the flick sensitivity to the initial value. When the main control unit 202 determines that the destination has been reached, the main control unit 202 inputs a command for returning the flick sensitivity to the initial value to the sensitivity adjustment unit 208. The sensitivity adjustment unit 208 returns the flick sensitivity to the initial value in accordance with a command from the main control unit 202 to return the flick sensitivity to the initial value. As a result, the flick sensitivity in the direction from the departure point (current location) to the destination and the flick sensitivity in other directions are set to be the same.

  If it is determined in step S422 that the destination has not been reached in step S418, the navigation device 100 determines whether or not the destination has been deleted. The main control unit 202 determines whether or not the destination has been deleted. If it is determined that the destination has been deleted, the process proceeds to step S420. If it is determined that the destination is not erased, the process returns to step S404.

  According to one embodiment of the navigation device, the touch panel flick operation sensitivity can be set based on the route information. For example, the flick operation sensitivity in the direction along the route information is increased. By doing so, the moving speed of the scroll in the direction along the route information becomes higher than the moving speed of the scroll in the direction other than the direction. For this reason, even during driving, information in the vicinity of the route to the destination can be easily followed by a flick operation, and can be scrolled to the vicinity of the destination without gazing at the screen of the navigation device.
