Description

  The present invention relates to a navigation device and a display method that also perform a parking lot search when performing a route search to a destination.

  In general, a navigation device mounted on a vehicle such as an automobile performs a route search to a set destination based on the vehicle position and map data, and displays or sounds to a user such as a driver. Provide route guidance. In this case, when going to a famous place such as a sightseeing spot or a place where there are many users such as a station, there is a case where a parking lot is provided nearby.

  However, if the destination, such as a facility that does not have a parking lot at the destination, will arrive near the destination and the user will search for the surroundings, In general, a parking lot is searched and displayed, and the user selects one parking lot from among the parking lots. That is, after a user arrives near the destination, the surrounding parking lot is searched.

  However, since there are many unclear points such as the parking lot usage status (whether it is full), usage fee, parking lot environment (presence of paving, vehicle width limitation, height limitation, etc.), there are many unclear points. It is difficult to confirm in advance whether the vehicle is a parking lot where parking is possible. For this reason, if the parking lot selected by the user is full, or if it is a parking lot that cannot be parked due to restrictions such as the vehicle width or height of the host vehicle, further search for nearby parking lots is performed. There is a problem that it has to be displayed and moved, and it takes time and effort to search for an optimal parking lot.

  The present invention has been made to solve the above-described problems, and automatically searches for parking lots around a destination and guides routes around a plurality of parking lot candidates when the destination is reached. An object of the present invention is to provide a navigation device and a display method that can be used.

In order to achieve the above object, the present invention provides a navigation device carried in or mounted on the vehicle for searching a route from the current location of the vehicle to the destination based on the current location of the vehicle and map data. Based on the destination and the destination, a parking lot around the destination is searched, and a predetermined number of two or more predetermined parking lots are set in descending order of the word-of-mouth ranking of the parking lot from the searched parking lots. And at least one of the parking lot candidates based on the parking lot candidates determined at the destination parking lot search unit and the current location of the vehicle and the destination surrounding parking lot search unit. A parking lot display control unit that, when within a predetermined distance from the current location of the vehicle, determines a circulation route of the predetermined number of parking lots and gives an instruction to display the circulation route The parking in response to an instruction from the display control unit, characterized by comprising a display unit for displaying the parking circular route of the predetermined number.

  According to the present invention, it is possible to save the trouble of searching for a parking lot by searching for the surroundings after arriving near the destination. It is possible to save the trouble of re-searching for a parking lot without being able to park because it does not fit, and it is possible to search for a parking lot and park at a favorite parking lot very efficiently.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
Embodiment 1 FIG.
FIG. 1 is a block diagram showing the configuration of a user terminal and a server according to Embodiment 1 of the present invention. In the first embodiment, the user terminal 10 functions as a navigation device that performs a route search from the current location of the vehicle to the destination based on the current location of the vehicle such as an automobile and map data. It communicates with the user terminal 10 to transmit / receive information.

  The user terminal 10 that is a navigation device includes an input unit 11, a display unit 12, a communication unit 13, a vehicle position detection unit 14, and a guidance display control unit 15. The user terminal 10 is installed and used in a vehicle such as an automobile.

  The input unit 11 receives manual input from the user, and is installed on a hardware switch, key, button, touch sensor integrated with the display unit 12 or a handle provided in the user terminal 10. Any type of remote control may be used.

  The display unit 12 presents information to the user in response to an instruction from the guidance display control unit 15 such as an LCD (Liquid Crystal Display) or an organic EL display. Further, as described above, it is a display-integrated touch panel, and may be composed of, for example, an LCD and a touch sensor.

  The communication unit 13 communicates with the server 20 and transmits and receives information, and includes at least a map data acquisition unit 31 and a parking lot availability information reception unit 32. And in this Embodiment 1, the server 20 has memorize | stored map data, and the user terminal 10 which is a navigation apparatus acquires map data from the server 20 via the map data acquisition part 31. FIG. Moreover, the parking lot availability information described later is received via the parking lot availability information receiving unit 32.

In addition, although demonstrated as what acquires map data from the server 20 here, the user terminal 10 which is a navigation apparatus may be provided with the map data memory | storage part, and the map data may be memorize | stored.
The own vehicle position detection unit 14 detects the current position of the own vehicle using, for example, GPS (Global Positioning System).

The guidance display control unit 15 includes a route guidance search unit 51, a route display control unit 52, a destination surrounding parking lot search unit 53, and a parking lot display control unit 54.
The route guidance search unit 51 is based on the vehicle position detected by the vehicle position detection unit 14 and the map data acquired by the map data acquisition unit 31, and the route to the destination set through the input unit 11 Perform a search to determine the best route.

In response to an instruction from the route guidance search unit 51, the route display control unit 52 causes the display unit 12 to display the determined optimum route.
The destination vicinity parking lot search unit 53 searches for a parking lot around the destination based on the map data acquired by the map data acquisition unit 31 and the destination set via the input unit 11, and is set in advance. A predetermined number of parking lot candidates are determined.

  The “predetermined number” is at least two (plural). This is not possible if there is only one parking lot candidate around the destination, such as when the parking lot is full or the vehicle conditions (vehicle width, height, etc.) are not met, Since re-searching is necessary, for example, “5 places” is set.

  Further, the “predetermined number” may be a number set by default or a number arbitrarily set by the user. In this embodiment, it is assumed that “5” is set as a predetermined number by default.

  Furthermore, the destination surrounding parking lot search unit 53 acquires vacancy information for each decided parking lot candidate via the parking lot availability information receiving unit 32, and the parking lot decided as a candidate is full. A process of searching for another parking lot and determining it as a parking lot candidate is also performed.

  The parking lot display control unit 54 determines the parking lot based on the own vehicle position (current location of the vehicle) detected by the own vehicle position detection unit 14 and the parking lot candidates determined by the destination surrounding parking lot search unit 53. When at least one of the candidates is within a predetermined distance from the current location of the vehicle, that is, when the host vehicle reaches a predetermined distance from at least one of the parking lot candidates, a predetermined number of parking routes And instructing the display unit 12 to display the circulation route.

  This is because depending on the location of the parking lot, there are cases where there is a limit for entering. For example, there may be a case where there is a median strip and it is not possible to enter the store on the right, or a case where the vehicle cannot reach the store even if it has arrived in the vicinity due to one-way traffic. Therefore, as soon as a predetermined distance is reached from the parking lot candidates around the destination, the optimal number of parking lots that are candidates can be smoothly viewed, and when the warehousing is decided, it is possible to enter the parking lot. Guide the circuit route.

FIG. 2 is a flowchart showing a parking lot search and display process in the guidance display control unit 15 of the user terminal 10 according to the first embodiment.
First, it is determined whether or not a destination is set by the user via the input unit 11 (step ST1). If the destination is set (in the case of YES in step ST1), whether or not a parking lot is attached to the destination set in step ST1 based on the map data acquired by the map data acquisition unit 31. Is determined (step ST2).

Here, when there is a parking lot at the destination (in the case of YES at step ST2), the process is terminated as it is, and the route guidance is started as usual.
On the other hand, when there is no parking lot at the destination (NO in step ST2), a parking lot around the destination is searched (step ST3), and a predetermined number (5) of preset parking lot candidates. Is determined (step ST4). In this case as well, route guidance as usual is started in parallel with the processing after step ST2.

  Then, it waits until the host vehicle reaches a predetermined distance from one of the determined predetermined number (five) of parking lot candidates (in the case of NO in step ST5), and the host vehicle is determined from the parking lot candidates by a predetermined number. When the distance is reached, that is, if there is a parking lot candidate within a predetermined distance from the current location of the host vehicle (YES in step ST5), the vacant information of each parking lot candidate is acquired (step ST6).

  The “predetermined distance” at this time may also be a distance set by default, for example, “1 km”, or may be a distance arbitrarily set by the user. In this embodiment, it is assumed that “1 km” is set as the predetermined distance.

  Based on the received vacancy information, it is determined whether the candidate parking lot is full (step ST7). If there is a full parking lot (in the case of YES in step ST7), the full parking lot is excluded from the candidates. Then, another parking lot candidate is added (step ST8), and the process returns to the process of receiving the vacant information of the candidate parking lot (step ST6).

If all the predetermined number (5) of the parking lot candidates are not full (in the case of NO in step ST7), the circulation route for circulating around the predetermined number (5) of parking lots is determined and displayed on the display unit 12. (Step ST9).
FIG. 3 is an example of a display screen showing the circulation route of the predetermined number (five) of parking lots determined in this way.

  First, it is assumed that parking lots 1 to 5 are determined as parking lot candidates from the parking lots around the destination 40 in the above-described step ST4. Then, one of the candidate parking lots 1 to 5 (in the example shown in FIG. 3A, the parking lot 1 closest to the current position of the host vehicle 41) is within a distance of 1 km. When the vehicle 41 arrives (in the case of YES at step ST5), the vacant information of the candidate parking lots 1 to 5 is acquired (step ST6).

If all the candidate parking lots 1 to 5 are not full (in the case of NO in step ST7), the circulation routes of five (predetermined number) candidate parking lots 1 to 5 are determined and displayed ( Step ST9).
FIG. 3A shows a state in which a candidate vehicle parking lot 1 → 3 → 4 → 5 → 2 and a route that can return to the parking lot 1 are determined and displayed.

  As a result, the user can actually see the candidate parking lots 1 to 5 and sensuously grasp whether it is easy to park, whether there is no problem such as vehicle width and height, or how far away from the destination 40. In addition, since it is possible to determine which parking lot to use, it is possible to park in a parking lot that suits the user's preference.

  When the user is in a hurry, or after looking at the route displayed as shown in FIG. 3A, it is considered that the first candidate parking lot 1 looks good from the distance to the destination 40, etc. In some cases, for example, the host vehicle 41 may be parked in the first candidate parking lot 1 without going around all the candidate parking lots 1 to 5 and the route guidance may be terminated.

  In addition, even after the circuit route as shown in FIG. 3A is displayed, the parking spaces 1 to 5 of the candidate parking spaces are not used until the own vehicle 41 is parked in some parking lot (until the route guidance is finished). Information is acquired (step ST6), and it is checked whether all the parking lots 1 to 5 are full (step ST7).

  This is because parking space availability changes from moment to moment, so parking lot availability information is obtained in real time, and when it is full, it is removed from the candidate until it becomes empty, and another candidate can be substituted. This is to add.

  For example, it is assumed that the parking lot 4 among candidates is full while the host vehicle 41 is traveling. In this case, since it is determined whether or not the candidate parking lot is full in step ST7, the full parking lot 4 is excluded from the candidates, and another parking lot 6 is added as a candidate (step ST8).

  And empty information is acquired about five new parking lots 1, 2, 3, 5, and 6 (step ST6), and if all these parking lots are not full (in the case of NO of step ST7). The circulation routes of these candidate parking lots 1, 2, 3, 5, and 6 are determined and displayed (step ST9).

  FIG. 3 (b) is a diagram showing the route determined in this way, and the route that can go around the candidate parking lot 1 → 3 → 5 → 6 → 2 and return to the parking lot 1. The state is determined and displayed.

  As a result, even if the candidate parking lot becomes full in the middle, it immediately decides an alternative candidate and displays the circuit route including that candidate, so you can receive it when it arrives full Therefore, it is possible to prevent an extra effort and time, such as having to search for another parking lot and go again.

  In this embodiment, when there is a full parking lot in the candidate parking lot, another parking lot candidate is added, but the full parking lot is excluded from the candidates. The circuit route may be determined and displayed.

  That is, for example, if the candidate parking lot 4 becomes full after the circulation route shown in FIG. 3A is displayed, the full parking lot 4 is excluded from the candidates, and the remaining candidate parking lots 1, 2 are displayed. , 3 and 5 are obtained, and if all of these parking lots are not full, the route of these four parking lots 1, 2, 3 and 5 may be determined and displayed. .

  FIG. 3 (c) is a diagram showing the circulation route determined in this way. The route that can be circulated in the order of candidate parking lots 1 → 3 → 5 → 2 and returned to the parking lot is determined. Is displayed.

  In this way, it is possible to save time and effort to determine and add another parking lot candidate, and for the user, there is no need to travel on a route that passes through a parking lot that cannot be parked because the vehicle is full. Can be parked in a parking lot suitable for the user's preference.

  As described above, according to the first embodiment, simply by setting a destination, a parking lot around the destination is automatically searched to determine a plurality of parking lot candidates. When you reach the vicinity, you will be presented with a route that allows you to go around the multiple parking lot candidates that you have decided, so you can save yourself the trouble of searching for a parking lot by searching for the surroundings after arriving near the destination. When you head for a parking lot, you can save yourself the trouble of searching for a parking lot again without being able to park because it is full or the vehicle conditions do not match. You can find and park at your favorite parking lot.

  In the first embodiment, the user terminal has a navigation function and performs route guidance. However, the server has a navigation function, and at least the destination and the current position (the user terminal is used) from the user terminal. The vehicle position may be received, and the server may process the guidance display control unit 15 to perform route guidance and roundabout route guidance for parking lot candidates to the user terminal.

Embodiment 2. FIG.
Since the block diagram showing the configuration of the user terminal and the server in the second embodiment of the present invention is the same as the block diagram shown in FIG. 1 in the first embodiment, the illustration and description are omitted. In the second embodiment shown below, compared with the first embodiment, conditions for searching for parking lot candidates around the destination are set (set or selected), and candidate parking lots are set in advance so as to meet the conditions. The point that is narrowed down.

FIG. 4 is a flowchart showing a parking lot search and display process according to the second embodiment.
First, it is determined whether or not a destination is set by the user via the input unit 11 (step ST11). If the destination is set (in the case of YES in step ST11), whether or not a parking lot is attached to the destination set in step ST11 based on the map data acquired by the map data acquisition unit 31. Is determined (step ST12).

Here, when there is a parking lot at the destination (in the case of YES at step ST12), this processing is ended as it is, and route guidance is started as usual.
On the other hand, if there is no parking lot at the destination (NO in step ST12), it matches the user's wishes and vehicle restrictions (vehicle height, width, etc.) in order to search for parking lots around the destination. It is confirmed whether or not the parking conditions are set (set or selected) (step ST13).

The setting of the parking lot condition may be performed in advance by the user, or the parking lot condition may be set (set or selected) after the destination is set.
For example, when there is no parking lot at the destination (NO in step ST12), a parking condition setting screen as shown in FIG. 5 is displayed and conditions are set (set or selected) for the user. I will let you.

  Here, the vehicle feature priority button 61 is a button for selecting a vehicle feature as a search condition for a parking lot so as to search for a parking lot that matches restrictions such as the vehicle width and height of the host vehicle. At this time, by selecting the vehicle feature priority button 61, a parking lot that meets the conditions is automatically searched based on the features of the host vehicle (information such as the vehicle width and height) stored in the vehicle. Alternatively, by pressing the feature setting button 65 of the vehicle next to the vehicle, the user sets a feature to be searched with priority, whereby a parking lot that matches the set condition is searched. You may do it.

  The parking feature priority button 62 is a button for selecting a parking feature as a parking search condition so that a user's favorite parking can be searched. The characteristics of parking lots are, for example, parking spaces such as multi-level parking lots or flat parking lots, paved (such as asphalt and concrete) or non-paved (gravel and soil), stopper type or gate type. Yes, by pressing the parking feature setting button 66 adjacent to the parking feature priority button 62, the user can set the detailed parking features that the user wants to search preferentially.

  Note that once this parking lot feature (parking environment) is set, parking lots that match the set conditions are searched by simply pressing the parking feature priority button 62. If the user wants to change the current condition, it can be set again from the parking feature setting button 66.

  The order button 63 with the lowest usage fee is a button for setting the parking lots to be searched in ascending order of the usage fee of the parking lot, and the word order ranking button 64 is a parking lot in the order of popularity ranking such as popularity. Is a button for setting to be searched.

  Thus, when the parking conditions are set (set or selected) (in the case of YES in step ST13), a parking lot that matches the parking conditions around the destination is searched (step ST14) and set in advance. A predetermined number (5) of parking lot candidates that have been determined are determined (step ST15). In this case as well, normal route guidance is started in parallel with the processing after step ST12.

  After that, it waits until the host vehicle reaches a predetermined distance from one of the determined predetermined number (five) of parking lot candidates (in the case of NO in step ST16), and the host vehicle determines from the parking lot candidates a predetermined number. When the distance is reached, that is, if there is a parking lot candidate within a predetermined distance from the current location of the host vehicle (YES in step ST16), the vacant information of each parking lot candidate is acquired (step ST17).

  The “predetermined distance” at this time may also be a distance set by default, for example, “1 km”, or may be a distance arbitrarily set by the user. In this embodiment, it is assumed that “1 km” is set as the predetermined distance.

  Based on the received vacant information, it is determined whether or not the candidate parking lot is full (step ST18). If there is a full parking lot (YES in step ST18), the full parking lot is excluded from the candidates. Then, another parking lot candidate is added (step ST19), and the process returns to the process of receiving the vacant information of the candidate parking lot (step ST17).

  When all the predetermined number (5) of the parking lot candidates are not full (in the case of NO in step ST18), the circulation route for circulating around the predetermined number (5) of the parking lots is determined and displayed on the display unit 12. (Step ST20).

  An example of the display screen showing the predetermined number (five) of parking lot routes determined in this way is the same as that shown in FIG. 3 in the first embodiment. If “sparking parking” is set as the parking search condition with priority given to parking features, only the parking lot is searched as a candidate parking lot, and the parking lot displayed on the display screen of the round route (Parking lots 1 to 6 in FIG. 3) are all three-dimensional parking lots.

  As described above, according to the second embodiment, by setting in advance a search condition for parking lots for determining parking lot candidates around the destination, it is possible to narrow down when determining parking lot candidates. Support, search for only parking lots that match the user's wishes, determine multiple parking lot candidates, and can circulate multiple parking lot candidates that the vehicle has decided to reach around the destination Since the route is presented, in addition to the effect of the first embodiment, it is possible to efficiently search for a parking lot that meets the user's wishes and park it in a favorite parking lot.

  In consideration of the case where it is not possible to decide by looking around by the round route, or the case where you want to refer to the popularity of the user when making a decision, etc., on the screen displaying the round route as shown in FIG. When a “ranking” button is provided and the button is pressed, the parking lots displayed as candidates are displayed in order of word-of-mouth ranking (popular ranking), or word-of-mouth information is displayed when the candidate parking lot displayed on the screen is touched. You may make it do.

  Furthermore, as a result of displaying and confirming the word-of-mouth information, if it is desired that the parking lot will not be determined as a candidate parking lot in the future, a “Delete” button etc. will be provided so that the parking lot can be deleted. You may make it delete from a candidate parking lot. Thereby, the parking lot will not be selected again.

  In addition, if you select (set) the order in which the usage fee is cheaper as a search condition for the parking lot, the candidate parking lots in the order of the lowest price among the parking lots within a predetermined range (distance) from the destination Is determined. Also in this case, a “list display” button is provided on the screen displaying the circulation route as shown in FIG. 3, and when the button is pressed, the parking lots displayed as candidates are displayed in a list in ascending order of the fare. May be.

  Further, in the condition setting screen shown in FIG. 5, the order button 63 with the lowest usage fee is used, but instead of the order button 63 with the lowest usage fee, the usage fee limit setting button is used to set the upper limit amount. May be. And when the upper limit amount of the usage fee is set, a parking lot that can be handled within that amount may be determined as a candidate.

  In this case as well, the “Ranking” button is provided on the screen displaying the circulation route as shown in FIG. A list may be displayed.
