BEST MODE FOR CARRYING OUT THE INVENTION

[0015] A navigation device and a process control method according to the present invention will be described below with reference to the accompanying drawings. The preferred embodiments of the processing control program and the recording medium will be described in detail.

[0016] (Functional configuration of navigation device)

First, a functional configuration of a navigation apparatus that is useful in the embodiment of the present invention will be described. FIG. 1 is a block diagram showing a functional configuration of a navigation apparatus that is useful for an embodiment of the present invention. A navigation device 100 that is effective in the embodiment is a computer terminal including a portable storage device that can move with a moving body.

Here, the moving body is an object that can move, such as a vehicle, a ship, or a human. The navigation device 100 is realized by, for example, a navigation device mounted on the vehicle when the mobile body is a vehicle, and a mobile phone owned by the person when the mobile body is human. It is realized by.

In FIG. 1, a navigation device 100 includes a storage device 101, a detection unit 102, a traffic information acquisition unit 103, an input unit 104, a control unit 105, and a determination unit 106. . The storage device 101 stores various data. Specifically, the storage device 101 stores, for example, map data and function data.

The detection unit 102 detects the current position of the moving body on which the navigation device 100 is mounted.

The current position of the moving object can be detected by receiving a GPS signal of GPS satellite power, for example. Further, for example, when the navigation device 100 is mounted on a vehicle, the GPS satellite force is used in response to the output value of the acceleration sensor or the vehicle speed sensor that detects the behavior of the vehicle in response to the received GPS signal. The current position of the moving body (vehicle) may be detected. The detection unit 102 always detects the current position of the moving object while updating the data.

[0020] The traffic information acquisition unit 103 acquires traffic information. Here, the traffic information is, for example, information such as traffic restriction points, congestion points, congestion lengths, and causes of congestion on general roads and expressways. The traffic information can be acquired using, for example, VICS (Vehicle Information and Communication System). VICS is a registered trademark.

The input unit 104 receives user instruction input. Specifically, the input unit 104 For example, an instruction input for specifying a destination point and an instruction input for specifying various functions are accepted.

The control unit 105 executes a navigation process using data stored in the storage device 101 and an update process of data stored in the storage device 101. Here, the navigation process is, for example, a map display process in which a map that follows the current position of the moving object detected by the detection unit 102 is displayed on the display screen.

[0023] Further, the navigation processing is, for example, when the moving body is guided to the destination, the current position force of the moving body detected by the detecting unit 102, and present in the vicinity of the guide point on the route to the destination. This is route guidance processing performed when In addition, the navigation processing is route re-search processing that is performed when the current position force of the moving body detected by the detection unit 102 deviates from the force on the route to the destination.

[0024] The navigation process may be a traffic information presentation process based on the traffic information acquired by the traffic information acquisition unit 103, for example. Here, the traffic information presentation process is a process of presenting a traffic jam location by superimposing it on a map displayed on the display screen or by presenting characters or figures indicating traffic information. is there.

[0025] In the traffic information presentation processing, for example, the location of the traffic jam location may be presented by voice, such as "There is a traffic jam occurring 100m ahead". When the current position of the moving body is detected by the detection unit 102, a traffic jam or a traffic restriction location near the current position may be presented. If there is a guidance along the route to a given point, there may be a traffic jam on the route.

In addition, the navigation process is a navigation process corresponding to an instruction input for which user power is also accepted by the input unit 104, for example. Specifically, for example, when a specific point is designated by the user's instruction input, the map information including the designated point is displayed on the display screen. In addition, the navigation process may be, for example, a process for displaying a menu screen for setting a target point on the display screen.

[0027] The data update process by the control unit 105 is a process of updating data stored in the storage device 101 using update data. Here, the update data is specific For example, in the case where the data stored in the storage device 101 is map data, the map data is obtained by adding data relating to newly constructed roads and facilities to the map data. The update data may be recorded on a portable recording medium, for example, or may be recorded on an external device that can communicate with the navigation device 100.

[0028] Upon updating, the control unit 105 may erase all data stored in the storage device 101 and then store the update data, or may store the data stored in the storage device 101. Erase in block units and store the update data corresponding to the erased blocks in sequence.

[0029] The determination unit 106 determines whether or not to execute a predetermined navigation process during the execution of the update process. Here, the predetermined navigation process is a navigation process that is selected according to the situation among the various types of navigation processes described above. When the determination unit 106 determines that the predetermined navigation process is executed during the execution of the update process, the control unit 105 described above executes the predetermined navigation process with priority. In other words, the update process being executed is stopped and the predetermined navigation process is executed. Here, “execution of the navigation process with priority” means that both processes are executed with the load applied to the navigation process made larger than the load applied to the update process.

[0030] (Data update processing procedure of the navigation device)

Next, a data update processing procedure of the navigation device 100 will be described. FIG. 2 is a flowchart showing a data update processing procedure of the navigation device 100. In the flowchart of FIG. 2, first, the control unit 102 waits for the start of data update processing (step S201: No), and when the update processing is started (step S201: Yes), predetermined navigation processing is performed. Whether or not to execute the Yong process is determined by the determination unit 106 (step S202).

In step S202, when the predetermined navigation process is executed (step S202: Yes), the predetermined navigation process determined to be executed in step S202: Yes is executed (step S203). In step S203, the predetermined navigation process may be executed in preference to the update process, or the ongoing update process is stopped. You can execute the prescribed navigation process.

On the other hand, if the predetermined navigation process is not executed in step S202 (step S202: No), the data update process is continued (step S204). In step S204, when both the navigation process and the update process are executed, the superiority or inferiority of these processes is processed arbitrarily. It yogumata be treated as no superiority or inferiority, even if the set is treated so as to give priority to the rough force Ji Medochi Raka good ヽ.

[0033] After the process of step S203 or step S204, it is determined whether or not the data update process has been completed (step S205). If not completed (step S205: No), the process returns to step S202 and ends. If so (step S205: Yes), the series of processing ends.

[0034] As described above, according to the navigation device 100 of the embodiment, when it is determined that the predetermined navigation process is to be executed during the execution of the update process, the predetermined navigation process is prioritized. The update process in progress can be stopped and the specified navigation process can be executed.

Therefore, the navigation apparatus 100 can appropriately execute a predetermined navigation process depending on the situation even during the data update process. Thus, the user can update the data while using the navigation device 100, and can update all the data in the shortest possible time.

[0036] Also, according to the navigation device 100 of the embodiment, when the current position of the moving body detected by the detection unit 102 exists at or near an intersection, a map that follows the current position The map display process for displaying on the display screen can be performed as a navigation process.

[0037] Therefore, the navigation device 100 can inform the situation at or near the intersection according to the current location of the user even during the data update process. This allows the user to update all data in the shortest possible time without hindering movement.

Furthermore, according to the navigation device 100 of the embodiment, the traffic information presentation process based on the traffic information acquired by the traffic information acquisition unit 103 can be performed as the navigation process. Therefore, the navigation device 100 can present traffic information to the user even during the data update process. As a result, the user can update all data as quickly as possible while grasping the traffic situation.

[0040] Furthermore, according to the navigation device 100 of the embodiment, when a user instruction input is received, the navigation processing corresponding to the instruction input when the instruction input is received can be performed. it can.

[0041] Therefore, the navigation device 100 can perform the corresponding navigation processing according to the user's instruction input even while data is being updated. As a result, the user can update all data in the shortest possible time while enjoying the navigation function according to the instruction input at the necessary timing.

[0042] Also, according to the navigation device 100 of the embodiment, when the current position is present in the vicinity of the guide point on the route according to the current position detected by the detection unit 102, the route The guidance process can be performed as a navigation process.

[0043] Therefore, the navigation device 100 can guide the route even while data is being updated. This allows the user to update all data in the shortest possible time without hindering movement.

[0044] Also, according to the navigation device 100 of the embodiment, when the current position of the moving object detected by the detection unit 102 deviates from the route, the route re-search process is performed as the navigation process. be able to.

[0045] Therefore, even if the navigation device 100 is updating data, if the mobile object deviates from the route, it can re-search for a route according to the current position of the mobile object. it can. This allows the user to update all data in the shortest possible time without hindering mobility.

Force for omitting illustration [0046] For example, during execution of the update process by the control unit 105, a situation determination unit is provided for determining the traveling status of the mobile body equipped with the navigation device, and is determined by the situation determination unit. Driving status power of the moving body Stops the display processing of the navigation information on the display screen in the navigation processing when the driving status is the predetermined driving status.

The update process may be executed with priority. [0047] Here, the predetermined traveling state refers to, for example, guiding the moving body to travel along a road more than a predetermined distance during the route guidance processing for guiding the route among the various navigation processes described above. It is the situation that it is driving on the road where has been. In addition, the predetermined traveling situation may be, for example, a situation in which the moving body is traveling around a point registered as a home.

[0048] Further, the predetermined traveling situation may be a situation where the moving body is traveling on a road that has traveled in the past. In addition, the predetermined traveling state may be a state in which the moving body is traveling in the automatic traveling mode. Note that the automatic travel mode is a mode in which the control device mounted on the mobile body automatically travels by controlling the speed of the mobile body even if the user does not steer.

In this case, the display process of the navigation information on the display screen is stopped, but the navigation process is continuously performed. The display processing of the navigation information on the display screen is, for example, processing such as the above-described map display processing or traffic information presentation processing with display on the display screen. Note that “execution of update processing with priority” means that the load applied to the update processing is made larger than the load applied to the navigation processing and both processes are executed.

[0050] As described above, when the display process of the navigation information on the display screen is stopped while the resource is occupied by performing the update by the control unit 105, for example, "data update Only messages such as “medium” may be displayed on the display screen, or all information may be stopped.

[0051] Therefore, the navigation device 100 stops the navigation process with the display process on the display screen according to the traveling state of the moving body determined by the situation determination unit, and prioritizes the update process by the control unit 102. Can be made. As a result, the user can update all data in as short a time as possible by giving priority to data updating according to the traveling state of the moving object.

The data update is started when the optical disk 307 is inserted into the optical disk drive 306 or when an update start instruction operation is received by the user while the optical disk 307 is inserted into the optical disk drive 306.

[0079] When data update is started in step S401 (step S401: Yes), it is determined whether or not the instruction input has been accepted by operating the input device 311 (step S402). . In step S402, for example, it is determined whether or not a user instruction input related to navigation processing such as map scroll processing or destination setting processing has been accepted.

[0080] In step S402, if an instruction input is accepted (step S402: Yes), the process proceeds to step S408. If not accepted (step S402: No), it is determined whether route guidance is in progress. Judgment is made (step S403). Here, the route guidance is various processes for moving the vehicle along the optimum route to the destination point and various operations realized by the processes.

In step S403, when the route is not being guided (step S403: No), the process proceeds to step S406. If the route is being guided (step S403: Yes), it is determined whether or not the vehicle has approached the guidance point (step S404). If the vehicle has approached (step S404: Yes), step Move on to S408.

[0082] In step S404! /, If the vehicle is approaching the guide point! /, In this case (step S404: No), has the vehicle deviated from the route force used for route guidance? It is determined whether or not (step S405). If it deviates (step S405: Yes), the process proceeds to step S408. [0083] In step S405, if the vehicle does not deviate from the route force used for route guidance (step S405: No), it is determined whether or not the vehicle has received the traffic information in the vicinity of the current position. (Step S407). When the route is being guided, in step S407, it is also determined whether or not it is the power to receive traffic information existing on the route used for route guidance. If received (step S406: Yes), the process proceeds to step S408.

[0084] If traffic information has not been received (step S406: No), it is determined whether the vehicle has approached an intersection (step S407). If the vehicle has approached (step S407: Yes), step S408 is performed. Migrate to In step S408, the navigation process is executed prior to the update process, and the process proceeds to step S412.

Specifically, when the instruction input is accepted (S402: Yes), the navigation process corresponding to the instruction input is executed with priority. Further, when approaching the guidance point (S404: Yes), an enlarged map of the guidance point and information for guiding the traveling direction are displayed on the display 313, or a voice message for guiding the traveling direction is output.

[0086] When the vehicle deviates from the route (step S405: Yes), a new route is searched again according to the current position of the vehicle. Furthermore, when traffic information is received (step S406: Yes), information indicating a traffic jam location or a traffic regulation location is displayed on the display 313 or output by a voice message. In addition, when approaching an intersection (step S407: Yes), it is displayed on the map display 31 3 including the current position of the vehicle and the intersection. In step S408, the update process may be stopped as appropriate according to the navigation process to be executed.

[0087] In step S407, the current position force of the navigation device 300 is approaching the intersection! / If this is the case (step S407: No), the force that can be executed with priority given to the update process. It is determined whether or not (step S409). In step S409, it is possible to perform the data update process by using the resources related to the data update process among the various resources of the navigation device 300 with the highest priority for the data update process. Judge whether there is power. Examples of resources related to data update processing include CPU 301, ROM 302, RAM 303, magnetic disk drive 304, magnetic disk 305, optical disk drive 306, and optical disk 307. In step S409, if the update process can be executed with priority (step S409: Yes), the update process is executed with priority (step S410), and the process proceeds to step S412. In step S410, the display of the navigation information on the display screen of display 313 is stopped, and the update process is prioritized and executed over the navigation process. Note that only the display process is stopped for the navigation process, and the other processes continue.

On the other hand, if it is impossible to preferentially execute the update process (step S409: No), the normal process is executed (step S411), and the process proceeds to step S412. In step S411, the superiority or inferiority of the navigation process and the update process is arbitrarily processed. Yogumata be treated as no superiority may process set so as to prioritize either advance. However, the navigation information is displayed and the update process is not stopped.

Then, it is determined whether or not the update of all data files has been completed (step S412). If not completed (step S412: No), the process returns to step S402. If completed (step S412: Yes), the series of processing ends.

Next, the determination of whether or not the update process can be executed with priority in step S409 described above will be described. FIG. 5 is a flowchart showing a processing procedure for determining whether or not priority execution of update processing is possible. In the flowchart of FIG. 5, first, it is determined whether or not the update process has been preferentially executed, and whether or not more than tl has passed (step S501). If not, the process moves to step S508. Here, tl is set in advance, for example, at the time of manufacturing the navigation device 300, and can be arbitrarily set, for example, “tl = 30 seconds”.

In step S501, when priority execution of the update process is stopped and the force tl or more has elapsed (step S501: Yes), it is determined whether or not the route is being guided (step S502). If the route is not being guided (step S502: No), the process proceeds to step S505. When the route is being guided (step S502: Yes), it is determined whether or not the vehicle is driving on a road that is guided to travel on the road without making a right or left turn over a predetermined distance (step S503).

In step S503, if the vehicle is traveling on a road that has been guided to travel a predetermined distance or more (step S503: Yes), the process proceeds to step S509. If the vehicle is not traveling (step S503: No), it is determined whether the vehicle is traveling around the home (step S504). If the vehicle is traveling around the home (step S504: Yes), the process proceeds to step S509.

[0094] In step S504, if the vehicle is not traveling around the home (step S504:

For No), it is determined whether or not the vehicle is traveling on a road on which a travel locus is recorded (a road on which the vehicle has traveled in the past) (step S505). If the vehicle is traveling on the road where the travel locus is recorded (step S505: Yes), the process proceeds to step S509. If the vehicle is not traveling on the road where the travel locus is recorded (step S505: No), it is determined whether the vehicle is traveling in the automatic travel mode (step S506).

[0095] In step S506, if the vehicle is traveling in the automatic travel mode (step S5 06: Yes), the process proceeds to step S509. When the vehicle is not traveling in the automatic travel mode (step S506: No), it is determined whether or not the priority execution of the update process is stopped and the force has also exceeded t2 (step S507). Here, t2 is preliminarily set at the time of manufacturing navigation device 300, for example, and can be set arbitrarily, for example, “t2 = 5 minutes”. It is. Note that t2> tl.

[0096] In step S507, when the priority execution of the update process is stopped and the force t2 or more has not elapsed (step S: No), it is determined that the update process cannot be executed with priority (step S508). ) —End the series of processing. On the other hand, if the priority execution of the update process stops and the force has exceeded t2 (step S: Yes), it is determined that the update process can be executed with priority (step S508), and the series of processes ends. To do.

Next, a display screen example will be described. FIG. 6 is a plan view showing a display screen example.
