  A storage device 13 is a storage unit that stores various databases using a drive such as an HDD, a DVD-ROM, or a CD-ROM. In addition to the storage unit 13 and the map database (typically, a route search database and a map display database), other search data and map related data are also recorded.

  As described above, this map database includes two types for route search and map display, and the route search database includes data (nodes and links) necessary for route search. The links in the route search database have a common ID as a map ID and a road link for map display, and are associated with each other. On the other hand, the map display database includes detailed road shape information (shape point sequence), area shape information, and the like for display.

  In addition, a parking / parking prohibition area database is created in the storage unit 13 separately from the map database. This parking / forbidden area database includes N pieces of parking / forbidden area information in a format as shown in FIG.

  As shown in FIG. 2, a range (P1-P0, P2-P1,..., Pn-P0) composed of vectors obtained by sequentially connecting the coordinates P0 to Pn in the counterclockwise direction is a parking and stopping prohibited area 1, and each coordinate P'0. A range (P′1-P′0, P′2-P′1,... P′n-P′0) consisting of vectors obtained by sequentially connecting P′n in the counterclockwise direction is designated as a parking and parking prohibited area 2 Yes.

  As will be described later, when determining whether or not the vehicle position is within a parking and parking prohibited area, the area connecting the coordinates in the counterclockwise direction must be a convex polygon, and is a concave polygon. Is previously decomposed into a plurality of convex polygons as shown in FIG. Here, the actual process of decomposing a concave polygon into a convex polygon can be performed manually.

  In addition, the parking / parking prohibited area database is stored separately from the map database because the map database and parking / parking prohibited area database are not updated at the same time. This is because even if it is updated, it is desirable to rewrite the latest database for parking and stopping prohibited.

  In addition to the location information of the parking lots present in the map together with the map database, the storage unit 13 stores parking lot information such as business hours of each parking lot, parking fee, the number of vehicles accommodated and covered.

In addition to this, a hazard determination unit 34e is provided for determining the intention to park, and the hazard determination unit 34e detects the ON state of the hazard power supply mounted on the vehicle through the hazard sensor 12e of the vehicle information acquisition unit 12. If so, it is determined that there is an intention to park the vehicle.

  The seat belt wearing determination means 34f also includes an intention to park the vehicle when the seat belt non-wearing state is detected through the seat belt sensor 12f of the vehicle information acquisition unit 12. Judge that there is.

  In addition, when the parking determination unit 34 determines that the vehicle is parked or willing to park by any of the determination means 34a to 34f, the vehicle is actually parked or is in a state of being parked. Is determined. On the other hand, the parking determination unit 34, when a predetermined determination unit of the determination units 34a to 34f determines that the vehicle is parked or intends to park, the vehicle is actually in a parked state or is parked. Embodiment which determines with being in the state to be included is also included.

  For example, when it is determined that the vehicle is actually parked when the three determination units of the vehicle speed determination unit 34a, the parking brake determination unit 34b, and the engine determination unit 34c determine that the vehicle is parked. It is also possible to determine that the vehicle is actually parked only when it is determined that all of the determination means 34a to 34f are in a parking state or have an intention to park.

  35, from the current vehicle position to the parking lot based on the current position information of the own vehicle detected by the own vehicle position detection unit 31 and the position information of the parking lot in the vicinity of the own vehicle position searched by the parking lot search unit 33. It is a route calculation part which calculates the route candidate. The route calculation unit 35 is searched by the parking lot search unit 33 from the detected own vehicle position when the parking determination unit 34 determines that the vehicle is in a parked state or has an intention to park the vehicle. The route candidate to the parking lot is automatically calculated.

To output voice guidance. When the parking determination unit 34 determines that the vehicle is not in a parking state or does not intend to park, the voice control unit 37 uses the parking lot information near the vehicle position searched by the parking lot search unit 33. Based on this, voice data such as “A parking lot in the vicinity of the vehicle position has been found” is output to the display guide unit 7 for voice guidance.

  In addition, when a parking lot is not searched by the parking lot search unit 33, information indicating that the parking lot has not been found is notified to the user via the display guide unit 7 by voice. For example, voice data such as “No nearest parking lot was found” is output to the display guide unit 7 and voice guidance is given to the user.

  In addition, the voice control unit 37 displays the business hours, the number of accommodations, the parking fee, and the full / empty vehicle information (for example, FM multiplex reception and processing unit 1 and beacon reception and It is also possible to provide voice guidance with information such as acquired through the processing unit 2 as voice data.

[1.2. Action]
Next, the operation of the present embodiment based on the above configuration will be described below with reference to the flowcharts of FIGS. In FIG. 6, based on the determination whether the detected vehicle position is within the parking / restricted parking area, if it is within the parking / restricted parking area, a parking lot in the vicinity of the vehicle position is searched, and the parking area is automatically detected. The flow chart which carries out route guidance is shown. FIG. 7 shows a flowchart corresponding to a specific processing procedure for determining whether or not the detected vehicle position is within a parking and parking prohibited area.

[1.2.1. Automatic parking guidance process (Fig. 6)]
With reference to FIG. 6, the process procedure including the route guidance to the nearby parking lot searched when the own vehicle position is in the parking and parking prohibited area will be described below.

  First, as shown in FIG. 6, based on the information acquired from the vehicle information acquisition unit 12, the positioning unit 14, and the FM multiplex reception and processing unit 1, the current position information of the own vehicle is detected through the own vehicle position detection unit 31. (STEP601). When the own vehicle position detection unit 31 detects the current position information of the own vehicle, the parking / forbidden area determination unit 32 reads the parking / forbidden area database from the storage unit 13 into the memory, and the read / stop prohibition is read. It is determined whether or not the detected own vehicle position exists in the area (STEP 602).

  When the parking / parking prohibition area determination unit 32 determines that the detected vehicle position is within the parking / parking prohibition area (YES in STEP 602), the parking lot search unit 33 displays a parking lot in the vicinity of the vehicle position. Is searched (STEP 603). In addition, the parking lot near the own vehicle position includes a parking lot nearest to the own vehicle position and a plurality of parking lots included in a predetermined range centered on the own vehicle position.

  When the parking lot search unit 33 searches for a parking lot in the vicinity of the own vehicle position (YES in STEP 603), the parking determination unit 34 determines whether the user's vehicle is parked or willing to park. The determination is made based on the determination results of ˜34f (STEP 604). Specifically, in the present flow, as an example, when any of the determination units 34a to 34f recognizes the parking of the vehicle or the intention of parking, the vehicle is in a parked state or is in a state of being parked. Judge that there is.

  For example, the vehicle speed determination unit 34a determines that the vehicle is parked when the vehicle speed sensor 12a of the vehicle information acquisition unit 12 detects that the vehicle speed is 0 km / h for a predetermined time or more. In addition, the parking brake determination unit 34b determines that the vehicle is parked when the parking brake switch 12 detects the ON state of the parking brake switch through the parking brake sensor 12b of the vehicle information acquisition unit 12.

  The engine determination unit 34c determines that the vehicle is parked when the engine power of the vehicle is detected through the engine sensor 12c of the vehicle information acquisition unit 12. The mission determination unit 34d determines that the vehicle is parked when it detects a state in which the automatic transmission mounted on the vehicle is shifted to the parking range through the mission sensor 12d of the vehicle information acquisition unit 12.

  When determining the intention of parking, the mission determination means 34d repeatedly shifts the automatic transmission to the 1, 2, 3 speed range and drive range and shifts to the reverse range through the mission sensor 12d. It is determined that there is an intention to park the vehicle. The hazard determination means 34e determines that there is an intention to park the vehicle when the ON state of the hazard power supply mounted on the vehicle is detected through the hazard sensor 12e of the vehicle information acquisition unit 12. The seat belt wearing determination means 34f determines that there is an intention to park the vehicle when the non-wearing state of the seat belt is detected through the seat belt sensor 12f of the vehicle information acquisition unit 12.

  When the parking determination unit 34 determines in STEP 604 that the vehicle is actually parked or is in a state of being parked (YES in STEP 604), the route calculation unit 35 determines the parking lot search unit from the position of the vehicle. The guide route to the nearby parking lot searched by 33 is calculated, and the display control unit 36 and the voice control unit 37 guide the guide route through the display guide unit 7 (STEP 605).

  In STEP602, when the parking / parking prohibition area determination unit 32 determines that the position of the vehicle is not within the parking / stopping parking prohibition area (NO in STEP602), a notification to that effect and a search for a parking lot are not performed. This process is completed. Further, in STEP 603, when the parking lot search unit 33 does not search for a parking lot in the vicinity of the vehicle position (NO in STEP 603), a parking lot in the vicinity by either the display control unit 36 or the voice control unit 37. Is notified to the user via the display guide 7 (STEP 606).

  In STEP 604, when the vehicle is not parked or the presence of the intention to park cannot be found through the parking determination unit 34 (NO in STEP 604), the parking control unit 33 uses either the display control unit 36 or the voice control unit 37. The searched parking lot information is notified to the user (STEP 607). Specifically, as shown in FIG. 5, the searched parking lot is displayed on the map data, and in addition to this, notification is made by displaying parking hours, parking charges, etc., or voice guidance.

  In addition, this embodiment is not limited to the processing procedure based on the flowchart of the said FIG. 6, The said parking lot information is not given to a user, without performing route guidance to the parking lot which is the searched traffic regulation avoidance area. An embodiment for notifying is also included. Specifically, in SETP 603 in FIG. 6, when a parking lot in the vicinity of the vehicle position is searched, the parking lot information is notified on the condition that the vehicle is not in a parked state or in a state where parking is attempted. However, when the parking lot information near the own vehicle position is retrieved in STEP 603, the display control unit 36 and the voice control unit 37 notify the parking information information near the own vehicle position regardless of the parking state of the vehicle. Embodiments are also included. That is, the processing of STEP 604 is omitted, and parking information is notified based on the determination of YES in STEP 603.

[1.2.2. Parking and parking prohibited area determination flow (Fig. 7)]
Next, with reference to FIG. 7, a specific determination process of the parking / stopping-prohibited area determination unit 32 that determines whether or not the vehicle position is within the parking / stopping-prohibited area will be described below. That is, the determination process in STEP 602 on the flowchart of FIG. 6 described above will be described in detail.

  The parking / parking prohibition area determination unit 32 first reads a parking / parking prohibition area database from the storage unit 13 onto the memory when the host vehicle position detection unit 31 detects the position information of the host vehicle (STEP 701). Then, for each of the N parking and parking prohibited areas, it is determined whether the coordinates of the detected vehicle position belong to the area as shown in FIG. 4 (STEPs 702 to 705).

  Specifically, it is determined whether or not the vehicle position belongs to the I-th zone out of the N prohibited parking zones, and it is determined that the vehicle location is within the I-th parking prohibited zone. If it is determined (YES in STEP 704), the parking lot search unit 33 searches for a parking lot in the vicinity of the own vehicle position as YES in STEP 602 in FIG. 6 (STEP 603).

  On the other hand, if it is determined that the vehicle position is not within the I-th parking prohibition zone (NO in STEP 704), the determination process is repeated until the number of parking stops is N, and the vehicle position is It is determined whether or not each vehicle is within the parking prohibition (STEP 705). If it is determined that the vehicle position does not exist in all N parking / prohibited areas (NO in STEP 703), the process of this flow ends as NO in STEP 602 in FIG.

  According to the present embodiment as described above, even if the vehicle is traveling in an area having traffic regulation information such as a parking prohibited area or parked in the area, the vehicle automatically By searching for traffic regulation avoidance areas such as parking lots near the vehicle position, such search operations can be omitted, and the nearest traffic regulation avoidance area can be notified to the user and traffic can be guided to the avoidance area It is possible to provide a regulation avoidance area providing device, a control method thereof, and a control program. As a result, it is possible to prevent the vehicle from being parked or stopped in an area where parking and parking is prohibited by law, and to reduce inconvenience to the running vehicle and the surroundings.

[2. Other Embodiments]
The present invention is not limited to the embodiment in which the parking lot search unit 33 searches for a parking lot in the vicinity of the own vehicle position as described above. An embodiment in which route guidance to a parking lot with the lowest parking fee among the parking lots searched within the range is also included.

  Specifically, first, the parking lot search unit 33 does not search for the nearest parking lot with respect to the own vehicle position, but searches for a vehicle position that is slightly wider than when searching for a nearby parking lot. Search for parking lots that are within the central range. Then, the parking fee comparison unit compares the parking fee of each parking lot searched by the parking lot search unit 33 to select the parking lot with the cheapest fee, and the route calculation unit 35 selects the parking lot from the own vehicle position. The guidance route to is calculated.

  Thereby, for example, when parking of the vehicle is determined by the parking determination unit 34 and the user wants to save the parking fee to the extent that the user actually parks on the road, the parking lot is cheap even if it is slightly away from the vehicle position. Can be automatically guided.

  Here, the parking fee comparison unit selects the parking lot with the lowest parking fee. However, the present invention is not limited to this embodiment, and includes an embodiment that extracts all parking lots within a preset fee. To do. For example, an embodiment is also included in which a parking fee is set to 400 yen or less per hour in advance and a parking lot whose parking fee is within a predetermined range from the vehicle position is 400 yen or less per hour is notified. In addition, information on a plurality of searched parking lots may be displayed in a list in descending order of parking fee (or in ascending order), and the user may be allowed to select a parking lot for route guidance.

  In the above embodiment, parking / parking prohibited areas are described as an example of areas having traffic regulation information, but the present invention is not limited to the parking / parking prohibited areas, and the vehicle position is a parking lot prohibited area or Embodiments for determining whether the vehicle is in a prohibited parking area or an area having other regulatory information are also included.
