Perform the processing provided to the section. Thereby, the terminal device 3 and the vehicle can be linked, and the state of the vehicle can be smoothly shifted to the parking operation by the automatic parking function. Various information such as map information and parking lot information provided from the server 1 is stored in the storage device 303, and can be read out and used sequentially.

  In the navigation device of this embodiment configured as described above, a parking lot that can be parked by using the automatic parking function and a parking lot that is not parked are clearly notified to the user of the navigation device, and the request of the user is satisfied. Guides to the matching parking lot. Furthermore, when the self-propelled parking function is used, guidance in a parking lot and the execution of parking using the automatic parking function can be performed seamlessly in an automobile equipped with the self-machine.

[Details of processing performed by the navigation device]
Next, details of processing at the time of parking lot search and processing at the time of route guidance executed in each of the server 1 and the terminal device 3 that constitute the navigation device of this embodiment will be described with reference to flowcharts and the like. In the following, first, a process of the terminal device 3 in which an operation serving as a starting point of the process is performed by a user will be described, and then, a process of the server 1 will be described.

[Process Performed by Terminal Device 3]
In the terminal device 3 having the above-described configuration, details of processing at the time of searching for a parking lot and at the time of route guidance performed in cooperation with the server 1 will be described. FIGS. 5 and 6 are flowcharts for explaining processing performed in the terminal device 3. FIGS. 7 to 9 are displayed on the display unit 310D of the terminal device 3 in the processing illustrated in FIGS. FIG. 7 is a diagram for describing an example of a display screen that is displayed.

  The processing shown in FIGS. 5 and 6 is performed by selecting an item corresponding to a parking lot search process or a route search process from a predetermined menu displayed on the display unit 310D of the touch panel 311 of the terminal device 3 through the touch panel 311. This is executed by the control unit 302. First, the control unit 302 executes a map / navigation display request process for requesting the server 1 to perform a map display or a navigation display according to the item to be executed selected from the menu (step S101). That is, in step S101, the control unit 302 displays an input screen corresponding to the selected process on the display unit 310D, and receives input of necessary information through the touch panel 311. Then, in step S101, the control unit 302 controls the request etc. forming unit 321 to form a search request including information received through the touch panel 311 and transmits the search request to the server 1.

  For example, when the selected item is a parking lot search process, the server 1 receives the input of information indicating that the location to be searched and the search target is a parking lot, and forms a parking lot search request including these. Is transmitted in step S101. Note that, as the location to be searched, the latitude and longitude of the current location acquired through the GPS unit 307 can be used, or the name of a facility such as the address of a destination or the name of a station can be input and used. When the selected item is a route search process, input of information necessary for a route search such as a departure place, a destination, a waypoint, a toll road priority, a general road priority, etc. is accepted, and a route search including these is input. The process of forming a request and transmitting it to the server 1 is performed in step S101.

  Thereafter, the server 1 performs a search process according to the request transmitted from the terminal device 3 in step S101, and returns a search result including map information, parking lot information, and the like. Therefore, the control unit 302 performs a process of receiving the search result addressed to the own device from the server 1 and outputting the result (step S102). In the process of step S102, when execution of the parking lot search is instructed, a map display indicating the position of the parking lot is performed. Further, in the process of step S102, when execution of the route search is instructed, when a plurality of routes are searched, they are presented, the selection of the route used for the route guidance is accepted, and the selected route is set. Route guidance is performed using a map display to guide the route.

  In any case, in the map display, a parking lot mark is displayed at the location of the parking lot based on the parking lot information provided from the server. The parking lot mark displayed on the map and the corresponding parking lot information are managed in the terminal device 3 in a one-to-one correspondence. That is, when a parking lot mark displayed on the map is indicated, the parking lot information is associated with a corresponding key (numerical key) so that the parking lot information corresponding to the parking mark can be specified.

  FIG. 7A is a diagram illustrating an example of a map display displayed on the display unit 310D in step S102. Although various facilities and the like are displayed on the map, for the sake of simplicity of description, a case where the map is displayed only on the display of the parking lot, which is a feature of the present invention, is shown. In FIG. 7A, a conventional parking lot that cannot be parked by using the automatic parking function is located at a position indicated by a circled parking lot mark numbered 1, 2, 5, 6, 8, 9. It indicates that there is. In other words, the conventional parking lot does not permit (prohibits) parking using the automatic parking function for various reasons.

  Further, in the case of this embodiment, by using the parking lot information shown in FIG. 4, a number 4 is given, and parking is performed by the assist type automatic parking function at the position shown by the square parking lot mark MK1. Indicates that there is a possible parking lot. In addition, a number 3 is attached, and a position indicated by a diamond-shaped parking lot mark MK2 indicates that there is a parking lot that can be parked by the fully automatic type automatic parking function. The number 7 is attached, and the position indicated by the double-lined square parking lot mark MK3 indicates that there is a parking lot that can be parked by both the fully automatic parking function and the assisted automatic parking function. ing.

  As shown in FIG. 7A, a parking lot of a conventional type and a parking lot that can be parked using the automatic parking function are indicated by different parking lot marks. As a result, it is possible to clearly grasp where the parking lot that can be parked using the automatic parking function is located. Therefore, the user of the car who wants to park using the automatic parking function can find the target parking lot without hesitation. Note that, as shown in FIG. 7A, the display screen displayed on the display unit 310D in step S102 is provided with, for example, an “end” button at the upper right end. By operating the "end" button, the processing shown in FIGS. 5 and 6 can be ended by the user's intention.

  Then, after the process of step S102, the control unit 302 receives an operation input through the touch panel 311 (step S103). In this example, in step S103, an end operation, an operation to instruct to display detailed information of a parking lot, and an operation to specify a target parking lot are received. Here, the end operation is a tap operation on the “end” button described above. The display instruction operation of the detailed information of the parking lot is a single tap operation to the parking lot mark of the target parking lot. The specific instruction operation of the target parking lot is a double tap operation on the parking lot mark of the target parking lot.

  Thereafter, the control unit 302 determines whether or not the operation input received in step S103 is an end operation (step S104). In the determination process of step S104, when it is determined that the end operation has been received, the process proceeds to step S123 of FIG. 6 and performs a predetermined end process, which will be described later in detail, and performs the processes shown in FIGS. finish. When it is determined in the determination process of step S104 that the end operation has not been received, the control unit 302 determines whether or not the operation input received in step S103 is a display instruction operation for displaying detailed information on the target parking lot. Is determined (step S105).

  When it is determined in the determination process of step S105 that the display instruction operation of the detailed information on the target parking lot has been received, a process of displaying the detailed information on the designated parking lot is performed (step S106). As described above, the parking lot mark on the map is associated with the corresponding parking lot information. For this reason, in step S106, the control unit 302 controls the guidance processing unit 322 to extract necessary information from the parking lot information corresponding to the instructed parking lot mark, A process for displaying detailed information of the parking lot is performed.

  FIG. 7B is a diagram for describing a display example of detailed information on a parking lot. When the parking mark MK1 is instructed, a detailed display H1 is displayed in the vicinity thereof. In the detailed display H1, the parking lot is a parking lot that can be parked by the assisted automatic parking function. Currently, there are 40 empty spaces, of which eight are empty spaces that can be parked by the automatic parking function. It is shown that there is.

  Further, when the parking lot mark MK2 is instructed, a detailed display H2 is displayed in the vicinity thereof. In the detailed display H2, the parking lot is a parking lot that can be parked by the fully automatic type automatic parking function, and currently there are 78 empty spaces, of which 20 spaces can be parked by the automatic parking function. It is shown that When the parking lot mark MK3 is instructed, a detailed display H3 is displayed in the vicinity thereof. In the detailed display H3, the parking lot is a parking lot that can be parked by both the assisted automatic parking function and the fully automatic type automatic parking function. Currently, there are 60 empty spaces, and 15 of them are automatically parked. This indicates that the parking space is a vacant space that can be parked.

  After the detailed display of the designated parking lot is thus performed, the control unit 302 repeats the processing from step S103. The detailed displays H1, H2, H3, etc. can be erased in the process of step S106 by tapping the display portion of the touch panel 311 or tapping another parking lot mark. it can. Of course, it is also possible to keep the detailed display of all the designated parking lots displayed.

  In addition, it is assumed that it is determined in the determination processing in step S105 that a display instruction operation of detailed information on the target parking lot has not been received. In this case, the control unit 302 determines whether the operation input received in step S103 is a specific instruction operation for a target parking lot (step S107). In the determination processing of step S107, when it is determined that the specific instruction operation for the target parking lot has not been received, the control unit 302 repeats the processing from step S103.

  Also, it is assumed that it is determined in the determination processing of step S107 that a specific instruction operation for the target parking lot has been received. In this case, the control unit 302 controls the request etc. forming unit 321 to form a search request for a route for the specified parking lot, with the current position acquired through the GPS unit 307 as the departure point, and The data is transmitted to the server 1 (step S108). After that, since the route search result is returned from the server 1, the control unit 302 receives the route search result from the server 1, and outputs the searched route on the map displayed on the display unit 310D. (Step S109). Then, route guidance to the target parking lot is started (step S110).

  FIG. 8A is a diagram illustrating an example of the route guidance display of the searched route from the current position to the target parking lot displayed in step S109. As shown in FIG. 8 (A), in this example, the route from the current position P to the specified parking lot is indicated by an arrow, and voice guidance is also used to guide the route to the specified parking lot. Will be Although the route shown in FIG. 8A shows a simple case, the distance to the target parking lot is not long, but is effective in a place where it is difficult to understand.

After the process of step S110, the control unit 302 proceeds to the process of FIG. 6 , and determines whether or not the vehicle has arrived at the specified parking lot (step S111). The determination process in step S111 can be performed based on whether or not the current position acquired through the GPS unit 307 has reached the vicinity of any one of the entrance positions 1, 2,. is there.

  In the determination process of step S111, when it is determined that the vehicle has not arrived at the specified parking lot, the control unit 302 receives an operation input from the user (step S112), and determines whether or not an end operation has been performed. Is determined (step S113). In the determination processing of step S113, when it is determined that the end operation has not been performed, the control unit 302 repeats the processing from step S111. Further, in the determination processing of step S113, when the termination operation is performed and it is determined that there is no other operation, the control unit 302 proceeds to the processing of step S123 and executes a predetermined termination processing (step S123), and FIG. The process shown in FIG.

  When it is determined in the determination processing of step S111 that the vehicle has arrived at the specified parking lot, a confirmation screen as to whether or not to head to the automatic parking area is displayed and a confirmation input is accepted (step S114). FIG. 8B is a diagram showing an example of a confirmation screen displayed in step S114 as to whether or not to go to the automatic parking area. As shown in FIG. 8 (B), on the confirmation screen, a tap operation is performed on the “YES” button when heading to the automatic parking area, and “NO” when not heading to the automatic parking area. Tap operation is performed on the button. In addition, when it is not suitable for the automatic parking area, it is selected when parking using the automatic parking function does not have to be performed or when the use of the parking lot is stopped.

  Then, the control unit 302 determines whether or not an instruction to the automatic parking area has been issued in step S114 (step S115). If it is determined in the determination processing of step S115 that it has been instructed not to go to the automatic parking area, the process proceeds to step S123, performs a predetermined end processing, and performs the processing shown in FIGS. finish. If it is determined in the determination process of step S115 that the vehicle is directed to the automatic parking area, the control unit 302 controls the guidance processing unit 322 to execute the guidance process in the parking lot (step S116). .

  In step S116, the guidance processing unit 322 performs guidance processing in the parking lot using the parking lot guidance image data and the parking lot guidance message data included in the parking lot information of the parking lot. FIG. 9A is an example of a display image displayed at the time of guidance processing in a parking lot, and shows an example of guidance display to an automatic parking available area. As shown in FIG. 9, in the case of this example, in step S116, a guidance display for guiding the user of the terminal device 3 entering from the entrance IN to the automatic parking area is performed.

  Note that the example shown in FIG. 9A is a comparatively easy-to-understand example. However, there are cases in which the automatic parking available area is relatively difficult to understand, for example, at a specific portion on the third floor of a multistory parking lot. In such a case, the route from the entrance to the automatic parking available area is fine and easy to understand, and can be guided by images and voice messages.

  For this reason, when the parking lot has a plurality of entrances, the parking lot information includes position information indicating the position of each of the entrances. By matching, it is possible to specify which entrance has entered. By preparing the image data for guidance in the parking lot and the message data for guidance in the parking lot included in the parking lot information in accordance with each entrance, the guidance processing unit 322 determines whether the vehicle equipped with its own vehicle is mounted. Guidance in the parking lot can be made according to the entrance that entered.

  In the case of a parking lot that can be parked using the fully automatic parking function, for example, guidance is provided to a predetermined position at which the fully automatic parking function is executed. The predetermined position is a position at which a rider including a driver gets off the vehicle, and is a position where the vehicle can safely get off the vehicle, for example, a position near an entrance of a parking lot.

  After that, the control unit 302 receives an operation input from the user through the touch panel 311 (step S117). Then, in step S117, control unit 302 determines whether or not an end operation has been received (step S118). The determination process of step S118 is a process of determining whether the “end” button displayed on the display unit 310D has been tapped.

If it is determined in step S118 that the "end" button has been pressed, the process proceeds to step S123, where a predetermined end process is performed (step S123), and the processes shown in FIGS. 5 and 6 end. On the other hand, when the control unit 302 determines that the “end” button has not been pressed in the determination processing of step S118, the control unit 302 determines whether or not the vehicle on which the own device is mounted has stopped (step S119). This determination can be made, for example, based on whether or not the speed information provided from the vehicle through the input / output terminal 306 and the I / F unit 305 has become “0 km”. Although not shown in FIG. 2, when it is possible to determine that the own device is in a stopped state from the output of, for example, a six-axis sensor provided in the terminal device 3, it is determined that the vehicle equipped with the own device has stopped. Can be determined.

  Then, in the determination processing of step S119, when it is determined that the vehicle on which the own machine is mounted is not stopped, the processing from step S117 is repeated. When it is determined in the determination process of step S119 that the vehicle equipped with the own vehicle has stopped, a confirmation screen as to whether or not to perform automatic parking is displayed and a confirmation input is accepted (step S120). FIG. 9B is a diagram illustrating an example of a confirmation screen as to whether or not to perform automatic parking. As shown in FIG. 9 (B), the confirmation screen as to whether or not to perform the automatic parking includes a “YES” button when the automatic parking is performed, and a “NO” when the automatic parking is not performed. Buttons can be selected. When the "NO" button is operated, for example, when the vehicle is stopped at a stage where the vehicle has not reached the automatic parking available area, the vehicle is temporarily stopped at a place where the automatic parking is not executable, as shown in FIG. 9B. It is operated when the confirmation screen shown is displayed.

  Then, in step S120, control unit 302 determines whether or not an instruction to execute automatic parking has been issued (step S121). When it is determined in step S121 that the instruction to execute the automatic parking has not been issued, the control unit 302 repeats the processing from step S116. When it is determined in step S121 that an instruction to execute automatic parking has been issued, the control unit 302 controls the vehicle control unit 323 to form an automatic parking execution instruction, and transmits this to the I / F unit 305 and the I / F unit 305. The information is provided to the control unit of the vehicle through the input / output terminal (step S122). As a result, the control unit on the automobile executes the automatic parking function and performs automatic parking.

  Then, the control unit 302 returns the display on the display unit 310D to the state before executing the processing shown in FIGS. 5 and 6, or releases the connection with the server 1 by a predetermined end processing. (Step S123), and the processing shown in FIGS. 5 and 6 is terminated. Then, the parking process using the automatic parking function is started by the control unit on the vehicle side, and the guidance message and the image information for the user are displayed on the display unit of the terminal device 3 using the information provided from the control unit on the vehicle side. It can be displayed on 310D and provided. In addition, if necessary, under the control of the control unit of the vehicle, a confirmation operation or the like from the user may be received through the terminal device 3 and returned to the control unit of the vehicle to appropriately operate the automatic parking function. It becomes possible.

[Process Performed on Server 1]
Next, in response to the provision of a parking lot search request (peripheral search request) or a route search request from the terminal device 3, or the provision of a parking lot information registration request or an update request from the parking lot system 4, Details of the processing of the server 1 that performs the processing according to this will be described. FIG. 10 is a flowchart for explaining processing executed by the server 1.

  The process shown in FIG. 10 is a process that is constantly executed in the control unit 102 of the server 1. The control unit 102 receives a request addressed to the own device via the communication I / F 101 (step S201), and determines whether a request addressed to the own device has been received (step S202). In the determination processing of step S202, when it is determined that the request addressed to the own device has not been received, the control unit 102 repeats the processing from step S201.

  In the determination processing of step S202, when it is determined in step S201 that the request addressed to the own device has been received, the control unit 102 determines whether the received request is a parking lot search request (step S203). In the determination processing in step S203, when it is determined that the received request is a parking lot search request, the control unit 102 performs a search for a parking lot (step S204). In step S204, the control unit 102 controls the parking lot search unit 112 to extract parking lot information around the target position from the parking lot DB 106, and displays a map of an area including the locations of these parking lots. The map information to be displayed is extracted from the map information DB 104.

  Next, the control unit 102 transmits the search result of the parking lot to the requesting terminal device 3 (step S205). Specifically, in step S205, the control unit 102 controls the provided information forming unit 114, and supplies the parking information and the map information extracted by the parking lot searching unit 112 to the provided information forming unit 114. A process for forming transmission information from the information and transmitting the information to the requesting terminal device 3 is performed. After the processing in step S205, the control unit 102 repeats the processing from step S201.

  When it is determined in the determination processing in step S203 that the received request is not a parking lot search request, the control unit 102 determines whether the request received in step S201 is a route search request (step S206). In the determination processing of step S206, when it is determined that the received request is a route search request, the control unit 102 performs a route search (step S207). In step S207, the control unit 102 controls the route search unit 113 to search for a route from the departure point to the destination specified by the terminal device 3 using the road network data in the road network DB 105, and searches for the route. The map information for indicating the route that has been extracted is extracted from the map information DB 104.

  Next, the control unit 102 transmits the route search result to the requesting terminal device 3 (step S208). Specifically, in step S208, the control unit 102 controls the provided information forming unit 114, and supplies the information indicating the route searched by the route searching unit 113 and the map information to the provided information forming unit 114. A process for forming transmission information from the information and transmitting the information to the requesting terminal device 3 is performed. After the processing in step S208, the control unit 102 repeats the processing from step S201.

  When it is determined in the determination processing of step S206 that the received request is not a route search request, the control unit 102 executes a processing corresponding to the received request (step S209). In step S209, processing corresponding to various requests other than the parking lot search request and the route search request, such as the processing corresponding to the parking lot information registration request and the update request from the parking lot system 4, is performed. After the processing in step S209, the control unit 102 performs the processing from step S201.

  Thus, the navigation device of this embodiment can perform a parking lot search and a route search by cooperation of the server 1 and the terminal device 3. Then, when the map information is displayed on the display unit 310D of the terminal device 3, information provision in consideration of a parking lot that can be parked using an automatic parking function is used instead of simply indicating a position where the parking lot is located. Guidance processing can be realized, and further, coordination with a control function on the vehicle side can be realized.

[Effects of Embodiment]
In the navigation device including the server 1 and the terminal device 3 according to the above-described embodiment, when displaying the map information on the display unit 310D at the time of performing a parking lot search or a navigation process, parking is performed using the automatic parking function. It is possible to clearly distinguish between a parking lot that can be operated and a parking lot that is not. As a result, it is possible to confirm a parking lot that can be parked using the automatic parking function, and to use the parking lot.

  Further, route search and route guidance to the target parking lot can be executed only by a simple operation such as tapping the target parking lot position displayed on the map. In addition, in the case where a parking lot that can be parked using the automatic parking function is used and an automatic parking available area is provided, guidance to the automatic parking available area in the parking lot can be realized.

  Furthermore, when parking is performed using the automatic parking function, the terminal device 3 can instruct the control unit on the vehicle side to execute the automatic parking function, so that route guidance from the current position to the parking lot, The guidance from the entrance to the automatically parkable area and the execution of parking using the automatic parking function can be performed seamlessly, that is, as a series of processes.

  By realizing these, the navigation apparatus and the navigation method can appropriately and easily cope with a parking lot environment generated when the automatic parking function is put to practical use, and can improve the convenience for the user. In other words, it is possible to surely find a parking lot where the automatic parking function can be used, head toward the parking lot, and perform parking using the automatic parking function. Risks such as accidents can be effectively avoided.

[Modification]
In the above-described embodiment, a conventional parking lot, a parking lot that can be parked by using the assisted automatic parking function, and a parking lot that can be parked by using the fully automatic parking function. In the description above, the parking lots that can be parked using both the assist type and the fully automatic type are displayed using different parking marks, but the present invention is not limited to this. The different types of parking lots can be displayed based on differences in characters, figures, symbols, colors, or combinations thereof. That is, the type of parking lot can be displayed in various modes.

  In the above-described embodiment, the server 1 includes the map information DB 104, the road network DB 105, the parking lot DB 106, the parking lot search unit 112, and the route search unit 113, and performs the parking lot search and the route search in the server 1. did. Then, a search result including the map information is provided from the server 1 to the terminal device 3, and this is used by the terminal device 3. However, it is not limited to this.

  On the terminal device 3 side, a map information DB 104, a road network DB 105, a parking lot DB 106, a parking lot search unit 112, and a route search unit 113 are provided. The server 1 manages only the parking lot DB 106. Then, the terminal device 3 may receive the latest parking lot information from the server 1 and perform a parking lot search to perform the parking lot guidance or a route search to perform the route guidance. .

  Further, in the above-described embodiment, guidance to the parking lot and guidance within the parking lot are performed, but the invention is not limited to this. For example, when a target parking lot is specified and instructed, a reservation of a parking space of the parking lot can be made to the parking lot system of the parking lot via the server 1. In this case, vehicle number information (number information described on the license plate of the vehicle) registered in advance in the terminal device 3 and the type of parking space to be secured are transmitted to the parking lot system via the server 1. . Here, the type of parking space is usually a distinction such as for assisted automatic parking and fully automatic automatic parking.

  In this manner, in the parking lot, the reserved parking space is made unavailable to other vehicles, and if the vehicle number information confirms that the vehicle is the source of the reservation, the reserved parking space is not used. You only need to be able to park in the space. Specifically, a mechanism for preventing intrusion into a parking space and a mechanism for recognizing vehicle number information using a camera are provided. The mechanism for preventing entry into the space may be released to enable parking.

  If the automatic parking function available at the parking lot designated by the user (user) does not match the automatic parking function mounted on the user's car (automatic parking cannot be performed at the designated parking lot) The user is prompted to select another parking lot or the parking lot is controlled so as not to be selected. In other words, whether the automatic parking function of the vehicle on which the user rides is the parking assist function or the fully automatic automatic parking function is set in the terminal device 3 in advance.

  Then, as described with reference to FIG. 7, the automatic parking type of the parking lot information included in the parking lot search result provided from the server 1 is compared with the automatic parking function of the own machine, and the parking lot designated by the user is used. Assume that the automatic parking function available in the vehicle does not match the automatic parking function of the own vehicle. In this case, the control unit 302 functions so as to prompt the user to select another parking lot or perform control so that the parking lot cannot be selected.

  For example, when the automatic parking function of the own vehicle is a parking assist function and the designated parking lot corresponds only to a fully automatic automatic parking function, the control unit 302 determines that “the designated parking lot is It does not support the parking assist function. Please specify a parking lot that supports the fully automatic parking function. ", A message is displayed on the display unit 310D, or the sound is output from the speaker 313 through the audio output unit 312. Ask for a sound or to redo the parking instructions.

  Similarly, when the automatic parking function of the own vehicle is a fully automatic automatic parking function and the designated parking lot corresponds only to the parking assist function, the control unit 302 determines that “the designated parking lot is , It does not support the full automatic parking function. Please indicate the parking lot corresponding to the parking assist function. "On the display unit 310D or from the speaker 313 through the audio output unit 312. Ask for sounding or redoing the parking instructions.

  In this way, even if the user mistakenly designates a parking lot that does not match the automatic parking function of the own vehicle, an appropriate parking lot can be instructed without fail. It is possible to reliably prevent guidance to a parking lot that does not match the automatic parking function mounted on the vehicle.

[Others]
Further, as can be seen from the description of the above-described embodiment, the function of the parking lot information storage means is realized by the parking lot DB 106 of the server 1, and the function of the map information storage means is realized by the map information DB 104 of the server 1.
