  FIG. 1 shows the configuration of a navigation device according to an embodiment of the present invention. The navigation device 1 is used by being mounted on a vehicle, and includes a control unit 10, a vibration gyro 11, a vehicle speed sensor 12, a hard disk (HDD) 13, a GPS (Global Positioning System) receiving unit 14, a VICS (Vehicle Information and). Communication System) (registered trademark) information receiving unit 15, display monitor 16, speaker 17, and input device 18.

  The control unit 10 includes a microprocessor, various peripheral circuits, a RAM, a ROM, and the like, and executes various processes based on a control program and map data recorded in the HDD 13. Various processes for guiding the host vehicle to the destination are executed by the process performed by the control unit 10. For example, destination search processing when setting a destination, search processing for a recommended route to the set destination, calculation processing of the current position of the host vehicle, various image display processing, voice output processing during route guidance Etc. are executed. Moreover, the parking lot search process mentioned later is also performed by the control part 10.

  The vibration gyro 11 is a sensor for detecting the angular velocity of the host vehicle. The vehicle speed sensor 12 is a sensor for detecting the vehicle speed of the host vehicle. By detecting the motion state of the host vehicle at predetermined time intervals using these sensors, the position movement amount of the host vehicle is obtained, and thereby the current position of the host vehicle is calculated.

  The HDD 13 is a non-volatile recording medium that can store and hold recorded data. Various data including the control program and map data are recorded in the HDD 13. These data recorded in the HDD 13 are read out under the control of the control unit 10 as necessary, and are used for various processes and controls executed by the control unit 10.

  The map data recorded on the HDD 13 includes route calculation data, road data, and background data. The route calculation data is data used when searching for a recommended route to the destination. The road data is data representing the shape and type of the road. In the map data, the minimum unit of each road is called a link. That is, each road in the map data is composed of a plurality of links. The background data is data representing the background of the map. Note that the background of the map is various components other than roads existing on the map. For example, rivers, railways, green zones, various structures, etc. are represented by background data.

  The map data includes POI (Point Of Interest) data related to various types of facilities. For example, information on types and positions of various facilities such as accommodation facilities such as inns and hotels, restaurants, gas stations, and convenience stores is recorded in the POI data. Based on this POI data, an icon corresponding to the type of facility is displayed on the map.

  The GPS receiver 14 receives a GPS signal transmitted from a GPS satellite and outputs it to the controller 10. The GPS signal includes information on the position and transmission time of the GPS satellite that transmitted the GPS signal as information for obtaining the position of the host vehicle and the current time. Therefore, by receiving GPS signals from a predetermined number or more of GPS satellites, the current position and current time of the host vehicle can be calculated based on these pieces of information. The GPS receiver 14, the vibration gyro 11 and the vehicle speed sensor 12 described above detect the own vehicle position, that is, the current position of the own vehicle.

  The VICS information receiving unit 15 receives VICS information transmitted from the VICS center to the navigation device 1. When the VICS information receiving unit 15 receives this VICS information, various road traffic information including traffic jam information is acquired in the navigation device 1. The VICS information received by the VICS information receiving unit 15 is output to the control unit 10.

  The transmission of VICS information from the VICS center to the navigation device 1 is performed mainly by radio wave beacons installed on highways, optical beacons installed mainly on general roads, or FM multiplex broadcasting. . The radio wave beacon and the optical beacon transmit VICS information locally to the vehicle passing near the installation point by radio waves or light (infrared rays). In contrast, FM multiplex broadcasting can transmit VICS information to a relatively wide area.

  The display monitor 16 is a device for displaying various screens in the navigation device 1 and is configured using a liquid crystal display or the like. For example, a map around the current position of the vehicle is displayed on the display monitor 16. The contents of the screen displayed on the display monitor 16 are determined by screen display control performed by the control unit 10. The display monitor 16 is installed at a position where the user can easily see, for example, on the dashboard of the host vehicle or in the instrument panel. The speaker 17 outputs various sounds such as route guidance sound under the control of the control unit 10.

  The input device 18 is a device for a user to perform various input operations for operating the navigation device 1 and includes various input switches. The user operates the input device 18 to input, for example, the name of a facility or point desired to be set as a destination, select a destination from registered locations registered in advance, or display a map in an arbitrary direction. Or scroll. The input device 18 can be realized by an operation panel, a remote controller, or the like. Alternatively, the input device 18 may be a touch panel integrated with the display monitor 16.

  When the user operates the input device 18 to set a destination, the navigation device 1 performs a predetermined algorithm operation based on the above-described route calculation data using the current position of the host vehicle as the departure point, thereby Route search from to the destination. The route obtained by this route search is set as a recommended route to the destination. When the recommended route is set in this way, the recommended route is displayed on the map separately from other roads by a method such as using a color different from that of the other roads. Thereby, the user can easily recognize the recommended route on the map displayed on the display monitor 16. In addition, the navigation device 1 guides the host vehicle by instructing the traveling direction by an image or voice to the user so that the host vehicle can travel according to the recommended route. In this way, route guidance to the destination is performed.

  Next, parking lot search processing executed in the navigation device 1 will be described. When the user instructs the navigation device 1 to execute a parking lot search process by performing a predetermined operation, the navigation device 1 searches for a parking lot around the set destination and displays the search result on the display monitor 16. List on the screen. When the user selects one of the parking lots displayed as a list in this way, the navigation apparatus 1 guides the vehicle toward the selected parking lot.

  When displaying a list of the results of the above-mentioned parking lot search process, the navigation device 1 selects a parking lot (hereinafter referred to as the same-side parking lot) located on the same side as the destination with respect to the nearest road of the destination. Display is given priority over a parking lot located on the opposite side of the road from the destination (hereinafter referred to as the opposite parking lot). Specifically, the parking lot on the same side of the searched parking lots is displayed at the top of the list, and the parking lot on the opposite side is displayed at the bottom of the list. Thereby, the search result of a parking lot can be shown so that a user can select the same-side parking lot easily.

  FIG. 2 is an example of a map display screen by the navigation device 1. In this screen example, reference numeral 20 denotes the current position of the host vehicle, reference numeral 21 denotes a destination, reference numerals 22 to 26 denote parking lots P1 to P5 around the destination, and reference numeral 27 denotes a break in the central separation zone. The parking lots P1, P3 are located on the same side as the destination 21 with respect to the road closest to the destination 21, and the parking lots P2, P4, and P5 are on the opposite side of the destination 21 with respect to the road. positioned. That is, the parking lots P1, P3 are the same-side parking lots, and P2, P4, and P5 are the opposite-side parking lots.

  When the user instructs the navigation device 1 to execute a parking lot search process while the map screen of FIG. 2 is displayed, the navigation device 1 performs a parking lot search accordingly, and the searched parking lot is Listed. FIG. 3 is an example of a display screen of the parking lot search result at this time. In the screen example of FIG. 3, among the parking lots P1 to P5 of FIG. 2, the same-side parking lots P <b> 1 and P <b> 3 are displayed at the top of the list as indicated by reference numerals 31 and 32. Following this, the opposite parking lots P2, P4 and P5 are displayed in a list as shown by reference numerals 33, 34 and 35 below the list.

  In the screen example of FIG. 3, the parking lots on the same side are listed in the order of P1 and P3 in order of increasing distance from the destination 21. That is, the display order is determined with emphasis on the ease of going to the destination 21 by the user after getting off. On the other hand, the opposite parking lots are listed in the order of P5, P2, and P4 in order from the closest U-turn possible point to the destination 21, that is, in the example of FIG. . That is, the display order is determined with emphasis on ease of access to the parking lot by the vehicle. Thereby, even if there is no vacancy in the first opposite parking lot, the next opposite parking lot can be selected, so that it is possible to reliably park when making a U-turn.

  As shown in the screen example of FIG. 3, when any of the list items 31 to 35 displayed as a list is selected by a user operation, the parking lot corresponding to the selected list item is guided to the vehicle. Specified as the destination. And in the navigation apparatus 1, the vehicle guidance to the said parking lot by various images, an audio | voice, etc. is started. The parking lot search process in the navigation device 1 is performed by the process described above.

  In the screen example of FIG. 3, for each list item of reference numerals 31 to 35, “Left” or “Right” is used so that the corresponding parking lot is located on the left side or the right side of the road. "Is attached. “Left” indicates that the parking lot is located on the left side of the road, that is, on the lane, and “Right” indicates that the parking lot is located on the right side of the road, that is, on the opposite lane. Represents that. Here, since the destination 21 is located on the traveling lane side as shown in FIG. 2, in this example, “left” is displayed for the same-side parking lot, and “right” is displayed for the opposite-side parking lot. Each is displayed. Thereby, in the screen example of FIG. 3, the same-side parking lot and the opposite-side parking lot are displayed so as to be distinguishable from each other. In addition, when the destination 21 is located on the opposite lane side separately from the example of FIG. 2, contrary to the above, “right” for the same-side parking lot and “left” for the opposite-side parking lot. Are displayed.

  Further, in the screen example of FIG. 3, the distance from the destination 21 to the corresponding parking lot is displayed for each of the list items 31 to 35. This distance may be a linear distance between the destination 21 and the parking lot, or may be determined in consideration of the user's walking route from the parking lot to the destination 21.

  FIG. 4 shows a flowchart executed in the navigation device 1 during the parking lot search process described above. This flowchart is executed in the control unit 10 of the navigation device 1 when the user instructs the navigation device 1 to start a parking lot search by performing a predetermined operation using the input device 18. is there.

  In step S10, the control unit 10 sets a destination designated by the user by operating the input device 18 as a destination to be searched for parking lots. Here, as described above, the user operates the input device 18 to input the name of a facility or a spot that the user wants to set as a destination, or to select from a registered location registered in advance. You can set the search destination. Alternatively, when a recommended route to the destination has already been searched, that destination may be used.

  In step S20, the control unit 10 searches for a parking lot existing around the destination set in step S10. Here, based on the map data stored in the HDD 13, a parking lot located within a predetermined range from the destination is searched as a parking lot existing around the destination. In addition, you may determine the range which searches a parking lot according to the distance from the destination. Alternatively, a parking lot search range may be set between the intersections adjacent to each other on the road closest to the destination, and a parking lot existing along the road in the search range may be searched.

  In step S30, the control part 10 determines whether one or more parking lots were searched by the parking lot search of step S20. If one or more parking lots are searched around the destination, the process proceeds to step S40. On the other hand, when no parking lot is searched, the control unit 10 ends the flowchart of FIG. At this time, it is preferable to notify the user by means of an image or sound that there is no parking lot around the destination.

  In step S40, the control unit 10 determines whether there is a parking lot on the same side in the parking lot searched in step S20. When the searched parking lot includes at least one same-side parking lot, the process proceeds to step S50. On the other hand, if no parking lot on the same side is included in the searched parking lot, the process proceeds to step S60 without executing step S50.

  In step S50, the control unit 10 displays a list of the same-side parking lots among the parking lots searched in step S20 on the screen of the display monitor 16. At this time, the list items representing each of the searched parking lots on the same side are displayed side by side in the order of the distance from the destination. Thereby, as shown in the list items 31 and 32 of FIG. 3, the search result of the parking lot on the same side is displayed as a list.

  In step S60, the control unit 10 determines whether or not there is an opposite parking lot in the parking lot searched in step S20. If at least one opposite parking lot is included in the searched parking lot, the process proceeds to step S70. On the other hand, if none of the searched parking lots is included in the searched parking lot, the process proceeds to step S90 without executing steps S70 and S80.

  In Step S70, control part 10 sets a priority to each of the opposite side parking lots among the parking lots searched in Step S20. Here, depending on whether the destination and the road facing the parking lot can be crossed, priority is set for the opposite parking lot using different methods. A specific priority setting method will be described later in detail with reference to FIG.

  In step S80, the control unit 10 displays a list of the opposite parking lots on the screen of the display monitor 16 among the parking lots searched in step S20. At this time, the list items representing each of the searched opposite parking lots are arranged in the order according to the priority set in step S70, and are listed in the same list as the list of the same parking lots displayed in step S50. indicate. Thereby, following the list items 31 and 32 in FIG. 3, the search results of the opposite parking lot are displayed as a list as shown in the list items 33 to 35.

  In step S90, the control unit 10 determines whether any of the parking lots displayed as a list in at least one of steps S50 and S80 has been selected by the user. If the user selects any parking lot by operating the input device 18, the process proceeds to step S100.

  In step S100, the control unit 10 starts guiding the vehicle to the parking lot selected in step S90. Here, a route from the current position of the host vehicle to the selected parking lot is searched, and the vehicle is guided according to the route. If step S100 is performed, the control part 10 will complete | finish the flowchart of FIG. As described above, the parking lot search process is performed.

  Next, the priority setting processing procedure for the opposite parking lot executed in step S70 will be described with reference to the flowchart of FIG. In step S71, the control unit 10 determines whether or not the nearest road of the destination, that is, the road facing the destination and each searched parking lot can be crossed in the vicinity of the parking lot. As a result, if it is determined that crossing is not possible, the process proceeds to step S72. If it is determined that crossing is possible, the process proceeds to step S75. This determination can be made based on the determination result by determining the type of the road based on the map data. For example, if the road is a single-lane road, it is determined that the road can be crossed. judge.

  In addition, even if it is a one-lane road, if the opposite lane of the road is congested, it is preferable to determine that this road cannot be crossed. Here, the opposite lane of the road is a lane that faces the lane to be traveled when the host vehicle travels to the destination. The traffic situation on the opposite lane can be determined based on the VICS information received by the VICS information receiving unit 15.

  In step S72, the control unit 10 detects the current position of the host vehicle. Here, as described above, the current position of the host vehicle is obtained based on the detection result by the vibration gyro 11 and the vehicle speed sensor 12 and the GPS signal received by the GPS receiver 14.

  In step S73, the control unit 10 calculates the length of the route from the current position of the host vehicle detected in step S72 to each opposite parking lot. Here, for each of the detected opposite parking lots, a route is determined such that the parking lot is on the vehicle lane side, and the length of this route is calculated. For example, as shown in the example of FIG. 2, there is a median strip break 27 in front of the current position 20 of the host vehicle, and when the vehicle makes a U-turn, it can go to the opposite parking lots P2, P4 and P5. Then, the length of each route from the current position 20 of the host vehicle to the opposite parking lots P2, P4, and P5 via the cut line 27 of the median strip is calculated. The same applies when making a U-turn at an intersection. Alternatively, when the vehicle detours other roads and goes to the opposite parking lot without making a U-turn in the middle of the road, the length of the route including the detour is calculated.

  In addition, when calculating | requiring the path | route to each opposite side parking lot by step S73, it is preferable to determine a driving | running | working lane by the path | route from which the road from a vehicle to the destination becomes the shortest. In other words, when the vehicle travels to the nearest road to the destination, the destination will be located on the opposite lane side, so a recommended route for detouring has already been set so that the destination is on the driving lane side. In such a case, it is only necessary to ignore this recommended route and obtain a route to each opposite parking lot.

  When the destination is on the opposite lane side with respect to the current position of the vehicle as described above, that is, when the opposite parking lot is located on the traveling lane side, the vehicle makes a U-turn or bypasses another road There is no need to do. Therefore, in such a case, what is necessary is just to obtain | require the length of the path | route when a vehicle progressed on the road with respect to each opposite side parking lot.

  In step S74, the control unit 10 gives priority to each opposite parking lot according to the travel distance from the current position of the host vehicle based on the length of the route calculated for each opposite parking lot in step S73. To set. Here, a higher priority is set assuming that the shorter the calculated route is, the shorter the travel distance from the current position of the host vehicle to the parking lot is. That is, in the example of FIG. 2, the higher priority is set in the order of the opposite parking lots P5, P2, and P4 in the order from the closest distance from the cut line 27 of the median strip that is the U-turn point.

  On the other hand, when it progresses to step S75 from step S71, the control part 10 sets the priority according to the distance from the destination with respect to each opposite side parking lot in step S75. Here, a higher priority is set as the distance from the destination is shorter.

  If the priority for each opposite parking lot is set by any method by executing one of steps S74 and S75, the control unit 10 ends the flowchart of FIG. 5 and completes the process of step S70 of FIG. To do. Based on the priority set in this way, a list of opposite parking lots in step S80 is displayed. As a result, the search results for the opposite parking lots are displayed in a list on the screen of the display monitor 16 in descending order of priority.

  According to the embodiment described above, the following operational effects are obtained.

(1) The navigation device 1 sets a destination located on one side of the road by the processing of the control unit 10 (step S10), searches for a parking lot around the destination (step S20), A list of the search results is displayed on the screen of the display monitor 16 (steps S50 and S80). At this time, the search result for the parking lot on the same side and the search result for the parking lot on the opposite side are listed in the same list, and the search result for the parking lot on the same side is displayed at the top of the list in step S50. By displaying the search result of the side parking lot in the lower part of the list, the search result of the same side parking lot is displayed with priority over the search result of the opposite side parking lot. Since it did in this way, when searching and displaying the parking lot which exists around the destination, it searches for a parking lot so that the user can easily select a parking lot located on the same side as the destination with respect to the road. Results can be presented.

(2) The control unit 10 determines whether or not the nearest road can be crossed (step S71), and in each of the opposite parking lots searched in step S20 by a different method according to the determination result. A priority level is set for this (step S70). In step S80, a list of search results for the opposite parking lot is displayed in the order corresponding to the priority. Because of this, a list of search results for the opposite parking lot is displayed according to the priority set in the optimal way depending on whether the vehicle can cross the road from the driving lane to the opposite parking lot or not. Can be displayed.

(3) When the nearest road can be crossed, the control unit 10 sets the priority according to the distance from the destination to the opposite parking lot (step S75). On the other hand, if the nearest road cannot be crossed, the length of the route from the current position of the vehicle detected in step S72 to the opposite parking lot is calculated (step S73), and priority is given according to the length of this route. The degree is set (step S74). Since it did in this way, when the nearest road can be crossed, a display order can be determined emphasizing ease of access to the destination by the user after getting off. On the other hand, when the nearest road cannot be crossed, the display order can be determined with emphasis on the ease of access to the parking lot by the vehicle, so that parking can be ensured.

(4) In step S71, when the nearest road is a one-lane road, it is determined that the road can be crossed, and when it is a multi-lane road, or when there is a median, it is determined that the road cannot be crossed. be able to. However, it is preferable to determine that it is impossible to cross the road if the opposite lane is congested even on a one-lane road. In this way, it is possible to reliably determine whether or not the nearest road can be crossed.

(5) When listing the parking lot search results on the screen of the display monitor 16 in steps S50 and S80, the control unit 10 displays “left” or “right” for each list item as shown in FIG. Is attached so that the search result of the parking lot on the same side and the search result of the parking lot on the opposite side can be distinguished from each other. The distance from the destination is also displayed. Since it did in this way, it can become reference when a user selects either parking lot.

  In the above embodiment, the search result of the parking lot on the same side is displayed at the top of the list in step S50, and the search result of the parking lot on the opposite side is displayed at the bottom of the same list in step S80. The search result of the parking lot is displayed with priority over the search result of the opposite parking lot. However, the search result of the same-side parking lot may be displayed with priority over the search result of the opposite-side parking lot by other methods.

  For example, the search result of the parking lot on the same side and the search result of the parking lot on the opposite side are displayed in different lists on different screens, and a list of search results for the parking lot on the same side is displayed first in step S50. Thereafter, when a predetermined operation is performed from the user or a predetermined time has elapsed, step S80 is executed to display a list of search results for the opposite parking lot. Even in this case, as in the above embodiment, when searching for and displaying a parking lot existing around the destination, the user can easily find a parking lot located on the same side as the destination with respect to the road. The search result of the parking lot can be presented so that it can be selected.

  Further, in the above embodiment, for each opposite side parking lot, a route in which the parking lot is on the vehicle lane side is obtained in step S73, and based on the length of this route, the current vehicle The example which sets the priority according to the travel distance from a position in step S74 was demonstrated. However, the priority according to the travel distance from the current position of the host vehicle may be set for each opposite parking lot without obtaining such a route.

  For example, as shown in FIG. 2, when there is a median strip break 27 in front of the current position 20 of the host vehicle, the distances from here to the opposite parking lots P2, P4, and P5 are obtained, and according to this distance By setting the priority, the priority according to the travel distance from the current position of the host vehicle can be set for each opposite parking lot. In addition, when detouring other roads and heading to the opposite parking lot, the priority can be set according to the distance from the destination and the point where the parking lot meets the road facing each other. The priority according to the travel distance from the current position can be set for each opposite parking lot. If the destination is on the opposite lane side of the current position of the host vehicle and the opposite parking lot is positioned on the driving lane side, the opposite direction is determined according to the distance from the current position of the host vehicle. What is necessary is just to set the priority of a side parking lot.

  In the above embodiment, when the road is not crossable, the priority according to the travel distance from the current position of the host vehicle is set in step S64 for each opposite side parking lot. The distance from the ground may be taken into account. For example, the travel distance from the current position of the host vehicle and the distance from the destination can be added together with a predetermined weighting ratio, and a priority according to the total value can be set for each opposite parking lot. Alternatively, instead of the distance from the destination, a path when a pedestrian crosses the road from each opposite parking lot to the destination may be used. In this case, a pedestrian crossing or a pedestrian bridge closest to the parking lot or the destination can be used as a pedestrian crossing point.

  In the above embodiment, the congestion situation of the parking lot is not taken into consideration, but the parking lot search result may be displayed taking this into consideration. For example, based on the parking lot information provided as a part of the VICS information, the congestion situation of the parking lot searched around the destination is determined. As a result, when it is determined that the parking lot is congested or full, the facility may be excluded from the list display target or a warning may be given to the user.

  The embodiment and various modifications described above are merely examples, and the present invention is not limited to these contents as long as the features of the invention are not impaired. Moreover, you may use the said embodiment and a modification in combination.
