  Exemplary embodiments of a navigation device, a navigation method, a navigation program, and a computer-readable recording medium according to the present invention will be explained below in detail with reference to the accompanying drawings.

  FIG. 1 is a block diagram showing a functional configuration of a navigation device according to an embodiment of the present invention. The navigation apparatus according to this embodiment includes a position recognition unit 101, a time zone detection unit 102, a determination unit 103, and a control unit 104.

  The position recognition unit 101 recognizes the current position of the vehicle. The time zone detector 102 detects the time zone to which the current time belongs. The determination unit 103 determines a task to be preferentially activated and executed according to the time zone to which the current position of the vehicle recognized by the position recognition unit 101 and the current time detected by the time zone detection unit 102 belong.

  When the position recognition unit 101 recognizes that the current position of the vehicle is in the vicinity of the home, and the time zone detection unit 102 detects that the current time corresponds to the work time zone, the determination unit 103 performs an audio task. Is determined to be executed with priority. Further, the determination unit 103 recognizes that the current position of the vehicle is in the vicinity of the work place by the position recognition unit 101, and detects that the current time corresponds to the return time zone by the time zone detection unit 102. It is determined that the audio task is activated first and executed preferentially.

  In addition, the determination unit 103 recognizes that the current position of the vehicle is neither the vicinity of the home nor the work place when the position recognition unit 101 recognizes that the current time is returned to the working hours or the time when the time is detected by the time zone detection unit 102. When it is detected that it does not correspond to the belt, it is determined that the task of searching for a map is started first and executed preferentially.

  Further, when the time zone detection unit 102 detects that the current date is a holiday, the determination unit 103 determines that the task of searching for a map is started first and executed preferentially. In addition, when the time zone detection unit 102 detects that the current date is a holiday and the current time is in the morning, the determination unit 103 performs a destination search function included in the task of searching for a map. It is determined to start first and execute preferentially. The control unit 104 starts and preferentially executes the task determined by the determination unit 103 and determined to be executed with priority over other tasks when the vehicle is started.

  FIG. 2 is a flowchart showing processing of the navigation method according to the embodiment of the present invention. First, the position recognition unit 101 recognizes the current position of the vehicle (step S201). Next, the time zone detector 102 detects the time zone to which the current time belongs (step S202). Next, the determination unit 103 determines a task to be preferentially activated and executed according to the time zone to which the current position of the vehicle recognized by the position recognition unit 101 and the current time detected by the time zone detection unit 102 belong. (Step S203). The control unit 104 prioritizes and executes the task determined by the determination unit 103 to be activated and processed with priority over other tasks when the vehicle is activated (step S204). Then, another task is activated (step S205).

  According to the embodiment described above, when a vehicle is started, it can be started from a necessary task and can be preferentially executed according to a boarding point and a time zone. For example, in the case of a commute route, it is conceivable that the navigation function is not used, and the user can use the audio function without waiting for the drawing of the map. For example, when the navigation function is considered necessary, the navigation function can be used with priority. At this time, the function that is actually used among the navigation functions can be activated and used according to the situation when the user gets on the vehicle.

  FIG. 3 is a block diagram showing a functional configuration of the navigation apparatus according to the embodiment of the present invention. The navigation device includes a navigation control unit 300, an operation unit 301, a display unit 302, a GPS receiver 303, a moving speed sensor 304, an angular velocity sensor 305, an HDD 306, a communication unit 307, a point search unit 308, a route search unit 309, and a route guidance unit 310. Consists of.

  The navigation control unit 300, the GPS receiver 303, the point search unit 308, the route search unit 309, and the route guidance unit 310 are, for example, a CPU (Central Processing Unit) that executes predetermined arithmetic processing, and a ROM ( It can be realized by a microcomputer configured by a read only memory (RAM) and a RAM (Random Access Memory) functioning as a work area of the CPU.

  The navigation control unit 300 controls the entire navigation device. The operation unit 301 includes operation buttons, a remote control, a touch panel, and the like. The navigation control unit 300 implements the position recognition unit 101, time zone detection unit 102, determination unit 103, and control unit 104 shown in FIG. The display unit 302 includes a liquid crystal display, an organic EL display, and the like.

  The GPS receiver 303 receives radio waves from GPS satellites and acquires the vehicle position information. Here, the vehicle position information is obtained by receiving a radio wave from a GPS satellite and obtaining a geometric position with respect to the GPS satellite, and can be measured anywhere on the earth. The radio wave is generated using an L1 radio wave carrying a C / A (Coarse and Access) code and a navigation message with a carrier wave of 1.57542 MHz. Thereby, the current position (latitude and longitude) of the vehicle is detected. Further, information collected by various sensors such as a moving speed sensor 304 and an angular speed sensor 305 described later may be taken into consideration.

  Then, based on the own vehicle position information acquired from the GPS receiver 303 and the map data stored in advance, the navigation control unit 300 outputs to the display unit 302 which position on the map is traveling.

  The movement speed sensor 304 detects the movement speed of the apparatus main body. When the apparatus main body is a vehicle, it is detected from the output side shaft of the transmission. The angular velocity sensor 305 detects the angular velocity when the host vehicle is rotating, and outputs angular velocity data, relative azimuth data, and data indicating the azimuth change amount.

  The HDD 306 is a hard disk drive, and executes data writing and reading with a nonvolatile magneto-optical disk. The HDD 306 stores map data, which will be described later, and displays a map on the display unit 302 when the navigation control unit 300 reads out the map data. And the navigation control part 300 updates the map data memorize | stored in HDD306 as needed.

  The communication unit 307 communicates with an external server via a wireless communication interface, and reads map data stored in the external server. The read map data is updated by the HDD 306. Moreover, the communication part 307 reads the update date of the map data of a server. The read update date and time is compared with the update date and time of the map data in the HDD 306 by the navigation control unit 300, and is used to determine whether or not to update the map data.

  The point search unit 308 searches for an arbitrary point based on the information input from the operation unit 301, and outputs this to the display unit 302. Further, the route search unit 309 calculates an optimal route to the point based on the point information obtained by the point search unit 308.

  Further, the route guidance unit 310 generates real-time route guidance information based on the information obtained by the route search unit 309 and the vehicle position information.

  FIG. 4 is an explanatory diagram for explaining the date, time, and place that are the determination criteria of the task. In this navigation apparatus, the current date 401, time 402, and place 403 are confirmed when activated. The date 401 is information indicating whether it is a weekday or a holiday. As for holidays, Sundays and public holidays can be determined from the calendar. However, it is also possible to classify a day as a holiday by inputting a user's rest day by user input.

  The time 402 is information indicating that it is a working time, a return time, or other time. The attendance time and return time are set by user input. If not set, a general return time of 8:00 to 9:00 and a return time of 17:00 to 19:00 are set as initial settings.

  The place 403 is information indicating that it is the vicinity of the home, the vicinity of the work place, or another place. The home position and the work location are set in advance by user input. Then, a certain range from the set position of the home and the position of the work place is set as the vicinity of the home and the work place.

  FIG. 5 is a block diagram for explaining the outline of the position recognition task, the search task, and the AV task. The navigation control unit 300 has a plurality of task execution functions. In FIG. 5, a search task 510, an AV task 520, and a position recognition task 530 are shown. The position recognition task 530 has a current position display function. The current position display function 531 displays the current position of the vehicle on the display unit 302 and is realized by the navigation control unit 300.

  The search task 510 includes a peripheral search function 512, a destination search function 513, and a route search function 514. The vicinity search function 512 is a function for searching the vicinity of the current location of the vehicle, and has a function for searching for the current location and a function for displaying a surrounding map. In addition, a user operation is accepted before drawing the map. The destination search function 513 is a function for searching for a destination of the vehicle, and includes a function for searching for a destination and a function for displaying a map of the destination. In addition, a user operation is accepted before drawing the map. The peripheral search function 512 and the destination search function 513 are realized by the point search unit 308. The route search function 514 is a function for searching for a route, and is realized by the route search unit 309.

  The AV task 520 includes a tuner operation function 521, a built-in HDD audio playback function 522, and an MD / CD-DA / DVD video playback function 523. Each unit constituting the AV task 520 is realized by the navigation control unit 300. The tuner operation function 521 has a TV / AM / FM tuner operation function. With this function, TV / AM / FM video / audio can be received. When the operation button is provided on the main body and this operation input is processed by a processor different from the navigation device CPU, it is not necessary to provide this function separately. However, this function is required when an operation switch is displayed on the screen and the touch panel is operated.

  The built-in HDD audio playback function 522 is a function for playing back the audio sound stored in the built-in HDD. Since it is stored in the HDD, it cannot be played back until the power is turned on, but playback is instructed via touch panel input, so it is necessary to display a touch panel screen. Therefore, the AV operation screen is preferentially displayed before map drawing. The MD / CD-DA / DVD video playback function 523 is a function for playing back music recorded on an MD, music recorded in a CD-DA format, and video images recorded on a DVD. While these cannot be played back until the power is turned on, playback is instructed via touch panel input, so it is necessary to display a touch panel screen. For this purpose, the operation screen is preferentially displayed before drawing the map.

  The search task 510 and the AV task 520 described above are executed with priority given to the situation when the engine is started. The following are examples of functions that are activated with priority given to the situation when the engine is started.

  (1) If the place, day of the week, and time of day when starting the engine are according to usual habits, it is highly possible that the place to go is known. Therefore, the AV task 520 is prioritized and the execution priority of the AV task 520 is given. Set the degree higher. As a result, the TV and audio operation playback function can be executed with priority. It is assumed that the location when the engine is started is backed up in a nonvolatile memory or the like.

  (2) If the engine startup location is more than the set distance from your home, or if it is not near your home, you are likely to be at a travel destination. And increase the execution priority of the search task 510. In particular, the current location display function 531 and the destination search function 513 can be executed with priority.

  (3) The search task 510 is started up when the engine start-up location is around the home and the day of the week is Saturday or Sunday, and the startup function is changed depending on the time zone. Since holidays vary depending on the user's occupation, the day of the week can be set. Specifically, when the time zone is morning, there is a possibility of going out, so the peripheral search function 512 and the destination search function 513 are activated with priority. When the time zone is from day to night, there is a high possibility of going out for shopping or eating, so the peripheral search function 512 is given priority.

  FIG. 6 is a flowchart for explaining task activation processing when the engine is activated. First, the engine is started (step S601). Next, the position recognition task is activated (step S602). Next, it is determined whether it is a holiday (step S603). That is, by checking the date 401, it is determined whether it is a current holiday or a weekday. In the case of a holiday (step S603: Yes), the process proceeds to step S611. If it is not a holiday (it is a weekday) (step S603: No), the current position is determined (step S604). That is, it is determined whether the place 403 is around the home, around the work place, or others.

  If the current position is around the home (step S604: around the home), it is determined whether or not the current working time zone (step S605). That is, by checking the time 402, it is determined whether or not it is a work time zone. When it is not the attendance time zone (step S605: No), the process proceeds to step S611. If it is the attendance time zone (step S605: Yes), the AV task 520 is activated (step S606). Then, the AV system operation can be accepted (step S608), and an indication that the AV operation is possible is displayed (step S609). Then, another task group is activated (step S610). For example, the search task 510 is activated. Then, a series of processing ends.

  In step S604, if the current position is in the vicinity of the work place (step S604: around the work place), it is determined whether or not the current time is a return home time zone (step S607). That is, by checking the time 402, it is determined whether or not it is the time to go home. If it is the time to go home (step S607: Yes), the process proceeds to step S606. If it is not the time to go home (step S607: No), the search task 510 is activated (step S611). Then, the search operation can be accepted (step S612), and the fact that the search operation is possible is displayed (step S613). Then, another task group is activated (step S614). For example, the AV task 520 is activated. Then, a series of processing ends. In step S604, when the current position is other (step S604: other), the process proceeds to step S611.

  Assuming that a car computer will appear as a future evolution of car navigation, by associating other functions (for example, many application software that can be executed on current personal computers) with the situation at the time of engine startup An application example in which the first application software to be automatically started is determined.

  According to the embodiment described above, after the engine is started, a user operation can be accepted as soon as possible with respect to the effective function at that time. Since it is possible to prioritize the functions that can be operated at startup in association with the conditions desired by the user, the functions desired by the user can be operated immediately after startup.

  The navigation method described in this embodiment can be realized by executing a program prepared in advance on a computer such as a personal computer or a workstation. This program is recorded on a computer-readable recording medium such as a hard disk, a flexible disk, a CD-ROM, an MO, and a DVD, and is executed by being read from the recording medium by the computer. The program may be a transmission medium that can be distributed via a network such as the Internet.
