In addition to the voice synthesized by the voice synthesizer, various kinds of sound and various kinds of guidance information recorded in advance on a tape, a memory, and the like can be output from the speaker.

  In the present embodiment, as shown in FIG. 3, the vehicle navigation apparatus 15 includes a route search unit 42 that searches for a route from the input departure point to the destination, from a functional viewpoint, The route registration unit 43 that stores and registers as a storage route together with the place and the destination, the route determination unit 44 that compares the route being traveled with the storage route, and the comparison result of the route determination unit 44 A screen switching unit 45 for switching screens and a screen registration unit 46 for registering standby screens are provided.

  Here, the route search unit 42 searches for a route from the departure place to the destination, as in a normal navigation device. Normally, the current location of the vehicle is automatically input as the departure location, but the operator can input an arbitrary location as the departure location. Then, the route search unit 42 accesses the database stored in the data recording unit 16 to search for a route so that the distance from the departure point to the destination is the shortest, or to shorten the required time. However, the route may be searched with reference to road traffic information such as VICS (R) information. When the route is set as a guidance target, that is, as a guidance route, the guidance route and guidance information along the guidance route are displayed on the screen of the display unit 35, or a voice output unit 37 is provided. The route guidance is performed by outputting the guidance information by voice.

  The route registration unit 43 is a route from the departure place where the vehicle traveled according to the route guidance to the destination, and after the vehicle has arrived at the destination, the route selected by the operator to be registered is the departure place. And it stores and registers in the route bank as a storage route together with the destination. The time zone passing through the route is also registered as the storage time zone together with the storage route. Here, the root bank is a storage area for storing and registering a storage path set in the storage means such as the data recording unit 16 and the ROM 33. Moreover, although the said memory | storage time slot | zone is a time slot | zone which drive | works on a memory | storage path | route on a daily basis like a commuting time, a commuting time, etc., for example, arbitrary time slots can also be set. Further, the storage time zone can be registered in association with a day of the week, a date, or the like. For example, it is possible to register such as 7:00 am to 8:20 am on days other than Saturday, Sunday and public holidays.

  Note that the route registration unit 43 may use a route other than the route on which the route guidance has been performed as a storage route. For example, a route that travels on a daily basis, such as a commute route or a school route, can be used as a storage route based on the travel locus of the vehicle. In this case, when the operator selects and registers the home, work place, school, etc. in advance as registration points, the travel locus of the vehicle connecting the registration points can be determined as a daily travel route. . Further, for example, a route that travels at a predetermined frequency or more, such as once a week or more, can be set as a storage route based on the travel locus of the vehicle. In this case, it is possible to determine a route that travels at a predetermined frequency or higher as a frequency that overlaps a predetermined frequency or more in the stored past vehicle travel trajectories.

  Further, the route determination unit 44 determines whether or not the current time is in the storage time zone registered in the route registration unit 43, and if so, the current position of the vehicle is further determined as the route registration unit. It is determined whether or not it is on the storage path registered in 43. That is, it is determined whether or not the vehicle is traveling on the storage route.

  Further, when the current time is in the storage time zone and the vehicle is traveling on the storage route as determined by the route determination unit 44, the screen switching unit 45 displays a standby screen on the screen of the display unit 35. Is displayed. The screen switching unit 45 determines whether there is traffic jam information for roads within a predetermined range around the storage route, and cancels the display of the standby screen if there is traffic jam information. When there is no traffic jam information, the standby screen is displayed on the screen of the display unit 35.

  The standby screen is a screen other than the original screen of the vehicle navigation device 15 such as a map display screen, an input item display screen, an operation screen, an information display screen, a guidance screen, etc., and is displayed on a display means of a personal computer, for example. Screen saver, wallpaper, etc., which may be a photo, a pattern, a painting, etc., a still image, a moving image, or any display content. The display content is stored and registered in advance in the data recording unit 16 or the ROM 33 by the screen registration unit 46.

  When there is traffic jam information for roads within a predetermined range around the storage route, the screen switching unit 45 displays a map display screen on the screen of the display unit 35. Thereby, the operator can grasp the traffic jam information around the storage path. Further, when the current time is not in the storage time zone, and when the vehicle is not traveling on the storage route even if the current time is in the storage time zone, the screen switching unit 45 similarly displays A map display screen is displayed on the screen of the unit 35.

  Further, the screen registration unit 46 stores and registers the display content in the data recording unit 16 or the ROM 33. In this case, it is desirable that a plurality of types of display contents are stored in the data recording unit 16 or the ROM 33, and the operator can select any display contents. Further, display contents such as an image taken by the operator with a digital camera and a screen saver downloaded from a personal computer may be uploaded to the data recording unit 16 or the ROM 33 and registered.

  Next, the operation of the vehicle navigation device 15 having the above-described configuration will be described. First, an operation for registering a route as a storage route in the route bank will be described.

  FIG. 4 is a flowchart showing an operation of registering the route of the vehicle navigation apparatus in the embodiment of the present invention in the route bank as a storage route.

  First, an operator such as a driver of the vehicle operates the input unit 34 to set a destination and perform a route search to the destination. Here, the departure point may be the current position of the vehicle, or the operator may set by operating the input unit 34. For example, when registering a commute route as a storage route, a work location that is the location of a company, factory, office, or the like as a work place is set as a destination, and a home is set as a departure location. As a result, the route search unit 42 searches for a route to the destination.

  Subsequently, the searched route is displayed on the screen of the display unit 35 and the route guidance is started, so that the operator starts traveling along the guided route. Thereby, route travel is started. Then, the route registration unit 43 stores the travel route of the vehicle. In this case, the route registration unit 43 stores a route from the departure place where the vehicle traveled to the destination according to the route guidance. In this case, the route registration unit 43 determines whether the vehicle has arrived at the set destination at predetermined time intervals (for example, 16 [msec]). When the vehicle arrives at the destination, the route registration unit 43 finishes storing the route, and allows the operator to select whether or not to store the currently traveled route in the route bank as the stored route. In this case, on the display screen of the display unit 35, a question as to whether or not to store the route traveled this time and selection means for selecting “store” and “not store” are displayed.

  Then, the route registration unit 43 determines whether the operator has selected “store” or “do not store”, that is, whether or not to register the stored route as a storage route. And when not registering, the said route registration part 43 erase | eliminates the memory | storage of the origin, the destination, and the path | route which carried out this time, and complete | finishes a process. Further, when registering, the route registration unit 43 stores and registers the stored route in the route bank as a storage route together with the departure place and the destination. Since the vehicle travel route is recorded based on the vehicle travel locus, the vehicle travel locus is registered as a storage route.

  Subsequently, the route registration unit 43 registers the storage time zone set by the operator by operating the input unit 34 together with the storage route, and ends the process. In addition, although the said memory | storage time slot | zone is a time slot | zone which drive | works on a memory | storage path | route like a commuting time, a commuting time etc., for example, arbitrary time slots can also be set. In addition, the route registration unit 43 can store a route on which the vehicle travels on a daily basis or a route on which the vehicle travels at a predetermined frequency or more as a storage route in the route bank.

Next, a flowchart will be described.
Step S1: A route search to the destination is performed.
Step S2: Route travel is started.
Step S3 The travel route of the vehicle is stored.
Step S4: It is determined whether or not the vehicle has arrived at the set destination. If the vehicle has arrived at the set destination, the process proceeds to step S5. If the vehicle has not arrived at the set destination, the process returns to step S3.
Step S5: It is determined whether or not the stored route is registered as a storage route. If the stored route is registered as a storage route, the process proceeds to step S6. If the stored route is not registered as a storage route, the process ends.
Step S6: Register the travel locus of the vehicle as a storage route.
Step S7: The storage time zone is registered and the process is terminated.

  Next, the operation of the vehicle navigation device 15 when the vehicle is traveling on the storage route will be described.

  FIG. 1 is a diagram showing an example of switching the screen of the vehicle navigation apparatus in the embodiment of the present invention, and FIG. 5 is a flowchart showing the operation of switching the screen of the vehicle navigation apparatus in the embodiment of the present invention.

  Here, it is assumed that a map display screen is displayed on the display unit 35 of the vehicle navigation device 15 as an initial screen as shown in FIG. In FIG. 1A, reference numeral 14 denotes a current position mark indicating the current position of the vehicle on the map. First, the route determination unit 44 determines whether or not the current time is within the storage time zone, that is, whether or not the current time is within the storage time zone registered in the route registration unit 43. If the current time is not within the storage time zone, the screen switching unit 45 does not switch the screen of the display unit 35 and keeps the map display screen as shown in FIG. Exit.

  When the current time is within the range of the storage time zone, the route determination unit 44 determines whether the current position is on the storage route, that is, the vehicle travels on the storage route registered in the route bank. Determine whether or not. If the current position is not on the storage path, the screen switching unit 45 does not switch the screen of the display unit 35 and keeps the map display screen as shown in FIG. .

  On the other hand, when the route determination unit 44 determines that the current position is on the storage route, the screen switching unit 45 determines whether there is traffic jam information for roads within a predetermined range around the storage route. If there is no traffic jam information, the screen switching unit 45 displays a standby screen as shown in FIG. 1 (b-1) or (b-2) on the screen of the display unit 35, and ends the processing. To do. The display content of the standby screen is registered in advance by the screen registration unit 46. And what is shown in FIG. 1 (b-1) is a photograph of the building, and what is shown in FIG. 2 (b-2) is a plain wallpaper that shows the same color as the dashboard of the vehicle It is.

  If there is traffic jam information, the screen switching unit 45 cancels the display of the standby screen, does not switch the screen of the display unit 35, keeps the map display screen displayed, and ends the process. In this case, since there is traffic jam information, the map display screen is as shown in FIG. 1C, and for example, a red arrow 13 is displayed as a mark indicating the traffic jam information.

  The above-described operation is repeatedly performed at predetermined time intervals (for example, 16 [msec]). Therefore, when a vehicle traveling on a location other than the storage route within the storage time zone travels on the storage route, a map display as shown in FIG. The screen is switched to a standby screen as shown in FIG. 1 (b-1) or (b-2). When the vehicle traveling on the storage route deviates from the storage route and travels on a place other than the storage route, the screen of the display unit 35 is shown in FIG. 1 (b-1) or (b-2). Is switched to a map display screen as shown in FIG. Furthermore, when the vehicle is traveling on the storage route, if the traffic information received by the communication unit 38 includes traffic jam information about roads within a predetermined range around the storage route, the screen of the display unit 35 is displayed. The standby screen as shown in FIG. 1 (b-1) or (b-2) is switched to the map display screen as shown in FIG. 1 (c).

Next, a flowchart will be described.
Step S11: It is determined whether or not the current time is within the storage time zone. If the current time is within the storage time zone, the process proceeds to step S12. If the current time is not within the storage time period, the process proceeds to step S15.
Step S12: It is determined whether or not the current position is on the storage path. If the current position is on the storage path, the process proceeds to step S13. If the current position is not on the storage path, the process proceeds to step S15.
Step S13: It is determined whether there is traffic jam information for roads within a predetermined range around the storage route. If there is traffic jam information for a road within a predetermined range around the storage route, the process proceeds to step S15.
Step S14: The standby screen is displayed and the process is terminated.
Step S15 The map display screen is displayed and the process is terminated.

  As described above, in this embodiment, a route having known road information such as a commuting route or a commuting route is stored as a storage route in advance and stored in the route bank together with the storage time zone. When the vehicle travels on the storage route within the range of the belt, a standby screen is displayed on the display unit 35. Therefore, since information unnecessary for the operator is not displayed, the operator can feel comfortable without feeling bothered, and the stress on the operator can be reduced.

  Further, a time zone in which the vehicle travels on the storage route on a daily basis, such as commuting time and school time, can be set as the memory time zone. For this reason, for example, when going out to another place via a storage route on a holiday, the map remains displayed even when traveling on the storage route. Like the peripheral information, the operator can acquire necessary information.

  Furthermore, since the operator can arbitrarily select the display content on the standby screen, the operator can feel more comfortable and the stress on the operator can be reduced more effectively.

  Further, when there is traffic jam information about roads within a predetermined range around the storage route, a map including the traffic jam information is displayed on the display unit 35, so that the operator can acquire necessary information at any time. .

  The present invention is not limited to the above-described embodiment, and various modifications can be made based on the spirit of the present invention, and they are not excluded from the scope of the present invention.
