BEST MODE FOR CARRYING OUT THE INVENTION

[0012] 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 described below in detail with reference to the accompanying drawings.

[0013] FIG. 1 is a block diagram showing a functional configuration of a navigation device that works 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. [0014] 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.

[0015] The determination unit 103 recognizes that the current position of the vehicle is in the vicinity of the home by the position recognition unit 101, and detects that the current time corresponds to the work time zone by the time zone detection unit 102. It is determined that the audio task is activated first and executed preferentially. 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.

[0016] In addition, when the position recognition unit 101 recognizes that the current position of the vehicle is neither the vicinity of the home nor the work place, or the time zone detection unit 102, the determination unit 103 determines that the current time is When it is detected that neither the time nor the time of returning home is detected, it is determined that the task of searching for a map is started first and executed preferentially.

[0017] In addition, 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 a map search task. It is determined to start first and execute preferentially. The control unit 104 activates and prioritizes the tasks determined by the determination unit 103 to be preferentially executed and prioritized over other tasks when the vehicle is activated.

[0018] FIG. 2 is a flowchart showing the processing of the navigation method that is effective in the embodiment of the present invention. First, the position recognition unit 101 recognizes the current position of the vehicle (step S 201). Next, the time zone detector 102 detects the time zone to which the current time belongs (step S202). Next, the determination unit 103 determines whether the current position of the vehicle recognized by the position recognition unit 101 and the time zone to which the current time detected by the time zone detection unit 102 belongs. A task to be activated and executed first is determined (step S203). The control unit 104 activates and prioritizes the tasks 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 the vehicle is started, the necessary task force can also be started and executed preferentially according to the boarding point and the time zone. For example, in the case of commuting routes, the navigation function may not be used, and the user can use the audio function without waiting for the map to be drawn. 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 in the navigation function can be activated and used according to the situation when the user gets on the vehicle.

Example

FIG. 3 is a block diagram showing a functional configuration of a navigation apparatus that is useful in 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 resino 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, a route. Consists of induction part 310

[0021] Note that the navigation control unit 300, the GPS receiver 303, the point search unit 308, the route search unit 309, and the route guide unit 310 are, for example, a CPU (Central Processing Unit) that executes predetermined arithmetic processing, and various control programs It can be realized by a microcomputer composed of a ROM (Read Only Memory) that stores data and a RAM (Random Access Memory) that functions as a CPU work area.

[0022] The navigation controller 300 controls the entire navigation device. The operation unit 301 includes an operation button, a remote control, a touch panel, and the like. By this navigation control unit 300, the position recognition unit 101, time zone detection unit 102, determination unit 103, and control unit 104 shown in FIG. 1 are realized. The display unit 302 includes a liquid crystal display, an organic EL display, and the like.

[0023] The GPS receiver 303 receives radio waves from GPS satellites and acquires own vehicle position information. Here, the vehicle position information is obtained by receiving the radio wave of GPS satellite force and obtaining the geometric position with respect to the GPS satellite, and can be measured anywhere on the earth. Radio waves are generated using a L1 radio wave with a CZA (Coarse and Access) code and navigation message on a carrier wave of 1.57542 MHz. This detects the current vehicle position (latitude and longitude). Furthermore, 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.

[0024] Then, based on the vehicle position information acquired from the GPS receiver 303 and the map data that has been memorized and stored! /, The navigation control unit 300 sends to the display unit 302 any map on the map. Runs the position and outputs whether or not.

[0025] The movement speed sensor 304 detects the movement speed of the apparatus main body. When the main body is a vehicle, it is detected from the output 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 non-volatile magneto-optical disk. The HDD 306 stores map data to be described later, and the navigation control unit 300 reads the map data and displays the map on the display unit 302. Then, the navigation control unit 300 updates the map data stored in the HDD 306 as necessary.

[0027] 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 on the HDD 306. The communication unit 307 reads the update date and time of the map data of the 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 the map data is updated.

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 optimum route to the point based on the point information obtained by the point search unit 308.

[0029] In addition, the route guidance unit 310 and the information obtained by the route search unit 309 and the vehicle position information Based on the above, real-time route guidance information is generated.

FIG. 4 is an explanatory diagram for explaining the date, time, and place that are the determination criteria of the task. This navigation device checks the current date 401, time 402, and location 403 when starting up. The date 401 is information indicating whether it is a weekday holiday. Ability to easily determine whether a holiday is a Sunday or a public holiday A user's holiday can be entered by user input, and the day can be classified as a holiday.

[0031] 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 it is not set, the default setting is a general return time of 8:00 to 9:00 and a return time of 17:00 to 19:00.

[0032] The place 403 is information indicating that it is the vicinity of the home, the vicinity of the work place, or another place. In advance, the position of the home and the position of the work place are set by user input. Then, a certain range from the set home position and work location is defined as the vicinity of the home and the work location.

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 location display function 531 is realized by the navigation control unit 300 by displaying the current position of the vehicle on the display unit 302.

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 the current location and a function for displaying a surrounding map. It also accepts user operations before drawing the map. The destination search function 513 is a function of searching for a destination of the vehicle, and has a function of searching for a destination and a function of 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.

[0035] The AV task 520 includes a tuner operation function 521, a built-in HDD audio playback function 522, M DZCD — Consists of DAZDVD video playback function 523. Each unit constituting the AV task 520 is realized by the navigation control unit 300. Tuner operation function 521 has a TV · AM 'FM tuner operation function. This function allows you to receive TV • AM 'FM video' audio. If there is an operation button on the main unit 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 the operation switch is displayed on the screen and the touch panel is used.

The built-in HDD audio playback function 522 is a function for playing back audio audio stored in the built-in HDD. Since it is stored in the HDD, it cannot be played until the power is turned on. On the other hand, since the playback is instructed via the touch panel input, it is necessary to display the touch panel screen. Therefore, prior to drawing the map, display the AV operation screen with priority. MDZCD—DAZDVD video playback function 523 is a function for playing back music recorded on MD, music recorded in CD—DA format, and video video recorded on DVD. While these cannot be played back until the power is turned on, playback is instructed via the touch panel input, so the touch panel screen must be displayed. For this purpose, the operation screen is preferentially displayed before drawing the map.

[0037] The search task 510 and the AV task 520 described above are executed with priority depending on the situation when the engine is started. The following are examples of functions that can be activated with priority given to the situation when the engine is started.

[0038] (1) If the place where the engine starts is the day of the week 'time is due to usual habits, it is highly likely that the place to go is known, so the AV task 520 is prioritized and the AV task 520 Set the execution priority of. As a result, the TV and audio operation playback function can be executed with priority. The location when the engine is started is assumed to be backed up in nonvolatile memory.

[0039] (2) If the engine start location is more than the set distance from your home, or if it is not around your home, it is highly likely that you are at a travel destination, so search task 510 is given priority. As a result, the execution priority of the search task 510 is set high. In particular, the current location display function 531 and the destination search function 513 should be executed with priority. [0040] (3) If the engine start location is near the home and the day of the week is Saturday or Sunday, the search task 510 is started, but 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 in the morning, there is a possibility of going out, so the peripheral search function 512 and the destination search function 513 are given priority. When the time zone is daytime or night, there is a high possibility of going out for shopping or meals.

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. If it is a holiday (Step S603: Yes), go to Step S611. If it is not a holiday (weekdays) (step S603: No), the current position is determined (step S604). That is, it is determined whether the place 403 is around the home or around the workplace.

[0042] 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 working time zone. If it is not in the working hours (step S605: No), the process proceeds to step S611. In the working hours (step S605: Yes), the AV task 520 is activated (step S606). Then, it accepts AV operations (step S608), and displays that AV operations are possible (step S609). Then, another task group is activated (step S6 10). For example, the search task 510 is activated. Then, a series of processing ends.

[0043] If it is determined in step S604 that the current position is in the vicinity of the work place (step S604: around the work place), it is determined whether or not the return time zone is currently available (step S607). That is, by checking the time 402, it is determined whether or not the return time slot power is good. If it is time to go home (step S6 07: 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, if the current position is other than Step S604: Others), go to Step S611.

[0044] If it is assumed that a car computer will appear as an evolution of car navigation in the future, other functions (for example, many application software that can be executed on the current personal computer) and engine startup An application example in which the first application software to be started automatically is determined by associating with the situation.

[0045] According to the embodiment described above, after the engine is started, user operations can be accepted as soon as possible with regard to effective functions at that time. The functions that can be operated at startup can be prioritized in association with the conditions desired by the user, so that the functions desired by the user can be operated as soon as possible after startup.

Note that the navigation method described in the present 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 reading the recording medium force by the computer. The program may be a transmission medium that can be distributed through a network such as the Internet.
