Description

  The present invention determines whether there is traffic regulation information such as parking prohibition information or the like at a set point, and when there is traffic regulation information, a regulation information providing apparatus that notifies the user of the information, its control method, and its control program About.

  In recent years, with the spread of automobiles and the development of information processing technology, navigation devices are rapidly spreading as in-vehicle information terminals that are mounted on a moving body such as a vehicle and perform route guidance. The navigation device uses map data prepared in advance and displays not only the current position information of its own vehicle, which is measured by GPS, on the surrounding map, but also calculates the route to the specified destination and displays it on the screen. And synthetic voices to guide the route.

  Here, a general route guidance method will be described. First, a storage medium such as a CD-ROM, DVD-ROM, HDD, etc., using a database selected by quantifying roads, place names, buildings, etc. on a map as map data. In advance, the user sets a destination by using the map data. Then, the position information of the own vehicle is estimated by using at least one of self-contained navigation using a gyroscope and a vehicle speed pulse, and radio navigation using GPS and FM multiplexing, and according to road data in the map database, Search and calculate the taxiway from the estimated vehicle position to the set destination. Thereby, the route guidance is realized by displaying the calculated guide route and the vehicle position on the screen while performing map matching.

  Here, when setting a destination in calculating a guidance route, a navigation device having a function of searching for a parking lot near the destination and guiding it to the destination has been proposed. If this device is used, even if there is no parking lot or other parking place at the calculated destination of the taxiway, if the user knows this beforehand, a parking lot near the destination will be opened. By executing the search function, it is possible to search for a route to the parking lot and guide the guidance.

  However, in the above apparatus, when the user knows in advance that there is no parking lot at the destination, the user searches for a parking lot near the destination at the time of setting the destination and searches for a route to the parking lot. . Therefore, when the user does not know that there is no parking lot in advance at the destination, the user is guided to the destination set for the route search, as in a general navigation device.

  That is, when there is no parking lot when arriving at the set destination, the user needs to perform an operation such as searching for the nearest parking lot on the spot. Since such operations require a certain amount of effort, the Tokyo Metropolitan Police Department will determine the parked location even if the operation is performed when the vehicle is parked at the destination. If you are in an area that has traffic control information such as priority control areas, places where parking on the road is particularly prohibited, parking prohibited areas and parking prohibited areas, it will cause trouble for vehicles and surroundings, and there will also be legal issues Become.

In view of this, there has been proposed a navigation device having a function of issuing an alarm by an alarm device when a vehicle is parked or stopped in an area having traffic regulation information when a point set as a destination is in the area having the traffic regulation information (Patent Literature). 1).

That is, when the parking / forbidden area determination unit 34 receives the location information of the destination set through the destination reception unit 32, the parking / forbidden area determination unit 34 reads the parking / forbidden area database from the storage unit 13 into the memory, It is determined whether or not this destination exists in the stop prohibited area.

  Whether the destination belongs to the prohibited parking area is determined by whether the coordinates of the destination are included in the prohibited parking area connecting the coordinates P0 to Pn counterclockwise as shown in FIG. It is judged by. Actually, the coordinates of the destination are (x, y), and the coordinates constituting the parking and stopping prohibited area are P0 (x0, y0), P1 (x1, y1), P2 (x2, y2)... Pn ( xn, yn), for example, considering the relationship between P1 and P0 and the destination, the following formula using a determinant based on the vector connecting P1 and P0 and the vector connecting the destination and P0: The establishment of [Equation 1] is a condition that the destination belongs to a parking and parking prohibited area.

[Equation 1]
Det = (x1−x0) × (y−y0) − (x−x0) × (y1−y0)
Det ≧ 0

  In the above, since the relationship with the destination is determined only between P1 and P0, the calculation of [Equation 1] is also performed between P2 and P1, P3 and P2,. It is determined that the destination is in the parking and prohibition area when Det ≧ 0 in the section. When Det> 0, the destination is located in the parking / restricted parking area.

[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. FIG. 5 shows a flowchart for searching for a parking lot in the vicinity of the destination when the set destination is in the prohibited parking area based on the determination whether the set destination is in the prohibited parking area. FIG. 6 shows a flowchart corresponding to a specific processing procedure for determining whether or not the set destination is in a parking and parking prohibited area.

[1.2.1. Overall flow (Figure 5)]
With reference to FIG. 5, a process procedure including a search process for a nearby parking lot when the destination is in a parking and parking prohibited area will be described below. In the present embodiment, the execution of the nearby parking lot search process when the destination is in the parking and parking prohibited area is based on the user's judgment through the input unit 9.

  First, as shown in FIG. 5, 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. (STEP501). Then, the destination receiving unit 32 receives the position information of the destination set by the user through the input unit 9 (STEP 502).

  When the location information of the destination set through the destination reception unit 32 is received, the parking / forbidden area determination unit 34 reads the parking / forbidden area database from the storage unit 13 into the memory, and the read out parking / forbidden area is read out. It is determined whether or not this destination exists within (STEP 503). If the parking / parking prohibition area determination unit 34 determines that the destination is within the parking / parking prohibition area (YES in STEP 503), the destination is in the parking / parking prohibition area via the display control unit 36. Information, for example, character data such as “the destination has been set in a parking and parking prohibited area” is output to the display guide unit 7 to notify the user (STEP 504).

  Further, it is not limited to the notification mode in which the character data is displayed on the display guide unit 7, but is information indicating that the destination is in a parking and parking prohibited area via the voice control unit 37. It is also possible to output voice data such as “set in the area” to the display guide unit 7 for voice guidance. In addition, information indicating that the received destination is determined to be within the prohibited parking area may be notified to the user through both the display using the character data and the voice guidance using the voice data through the display guide unit 7. it can.

  At the same time as notifying the user that the destination is within the prohibited parking area, the display guide unit 7 determines whether to search for a parking lot near the destination as shown in FIG. In order to make a selection, for example, a message such as “Do you want to search and guide the nearest parking lot? (Yes / No)” is displayed (STEP 505). When “Yes” is pressed through the input unit 9 which is a touch panel (YES in STEP 505), there is a nearest parking lot for the destination received by the destination parking lot search unit 35 by the destination reception block 32. (STEP 506).

  When the nearest parking lot is searched by the neighborhood parking lot search unit 35 (YES in STEP 506), the route calculation unit 33 uses the nearest parking lot as a pseudo destination and starts from the own vehicle position. The display control unit 36 and the voice control unit 37 perform guidance guidance for the guidance route via the display guide unit 7 (STEP 507). It should be noted that icons with different colors and shapes as shown in FIG. 7 may be attached to the respective parking lots as pseudo destinations and the destinations set through the destination receiving unit 32 so as to be discriminated. Is possible.

  In STEP503, when the parking / parking prohibition area determination unit 34 determines that the destination is not within the parking / parking prohibition area (NO in STEP503), the route calculation unit 33 calculates the destination reception unit from the detected vehicle position. The guidance route to the destination set through 32 is calculated, and the display control unit 36 and the voice control unit 37 perform guidance guidance on the guidance route via the display guide unit 7 (STEP 509). Further, in the case where “NO” is pressed through the input unit 9 which is a touch panel in STEP 505 (NO in STEP 505), the route calculation unit 33 is set through the destination reception unit 32 from the detected vehicle position in the same manner as described above. The guidance route to the destination is calculated, and the display control unit 36 and the voice control unit 37 guide the guidance route through the display guide unit 7 (STEP 509).

  In STEP 506, when the nearest parking lot search unit 35 has not searched for the nearest parking lot (NO in STEP 506), the display control unit 36 displays character data indicating that there is no nearest parking lot. The information is displayed through the guide unit 7 and notified to the user (STEP 508). The indication that there is no nearest parking lot can be used as voice guidance by the voice control unit 37, or voice guidance can be provided together with the display.

  In STEP 508, when the user is informed that there is no nearest parking lot via either the display control unit 36 or the voice control unit 37, the route calculation unit 33 passes the destination reception unit 32 from the own vehicle position. The guide route to the set destination 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 509).

[1.2.2. Parking and parking prohibited area determination flow (Fig. 6)]
Next, with reference to FIG. 6, the specific determination process of the parking / parking prohibition area determination unit 34 that determines whether or not the destination is in the parking / parking prohibition area will be described below. That is, the determination process in STEP 503 on the flowchart of FIG. 5 described above will be described in detail.

  First, when receiving the location information of the destination set by the user through the destination receiving unit 32, the parking / forbidden prohibited zone determining unit 34 reads the parking / forbidden zone prohibited database from the storage unit 13 into the memory (STEP 601). Then, for each of the N parking and parking prohibited areas, as shown in FIG. 4 described above, it is determined whether the set position coordinates of the destination belong to the area (STEPs 602 to 605).

  Specifically, it is determined whether or not the destination belongs to the I-th zone among the N prohibited parking zones, and the destination is determined to be within the I-th parking zone. In such a case (YES in STEP 604), as YES in STEP 503 in FIG. 5, the user is notified of information that the destination is in a parking and parking prohibited area (STEP 504).

  On the other hand, if it is determined that the destination is not in the I-th parking prohibition zone (NO in STEP 604), the number of parking prohibition zones is repeated until N stops, and the destination is within each parking stop prohibition. It is determined whether or not there is (STEP 605). If it is determined that there are no destinations in all N parking-prohibited areas (NO in STEP 603), the route from the vehicle position to a preset destination is determined as NO in STEP 503 in FIG. The calculation is performed by the route calculation unit 33, and the display control unit 36 and the voice control unit 37 guide the guidance route through the display guide unit 7 (STEP 509).

  As described above, according to the present embodiment, it can be determined at the time of setting the point whether or not the set point is in a parking and stopping prohibited area that is an area having traffic regulation information. It is possible to notify the user in advance whether the vehicle is in the parking / parking prohibition area without going to the set point.

  In addition, when the set point is in a parking and parking prohibited area, it is possible to automatically search for a parking lot near the set point, search for a route using the parking lot as a pseudo destination, and provide guidance It is. Therefore, it is possible to save the trouble of searching for a parking lot, to prevent parking in a parking prohibited area, and to reduce inconvenience to traveling vehicles and surroundings.

[2. Other Embodiments]
(A) In the above embodiment, the point to be determined whether or not the vehicle is in the parking and parking prohibited area is the “destination” set by the user, but the present invention is not limited to this. Also included is an embodiment in which it is determined whether or not the designated location is within the parking and prohibition area. In this case, even if the navigation operation is not provided, it is possible to determine whether or not the designated point belongs to the prohibited parking zone. If the point is in the prohibited parking zone, information indicating that is displayed. Alternatively, the user can be notified by either voice guidance.

  A processing procedure for determining whether or not a point designated by the user belongs to the parking / restriction prohibited area without providing a navigation operation will be described below with reference to the flowchart of FIG. First, as shown in FIG. 8, the destination receiving unit 32 (hereinafter referred to as a specified point receiving unit) receives the position information of the point designated by the user through the input unit 9 (STEP 801).

  When the location information of the designated location is received through the designated location accepting unit 32, the parking / parking prohibition area determination unit 34 reads the parking / parking prohibition zone database from the storage unit 13 into the memory, and the read parking / stopping zone prohibition area is read. Whether the designated point exists is determined (STEP 802). When it is determined by the parking / parking prohibition area determination unit 34 that the designated point is within the parking / parking prohibition area (YES in STEP 802), information indicating that the point is within the parking / parking prohibition area via the display control unit 36. For example, text data such as “the designated point is in the parking and prohibition zone” is output to the display guide unit 7 and notified to the user (STEP 803).

  Further, as in the above embodiment, the information is not limited to the notification mode in which the character data is displayed on the display guide unit 7, but is information that the point is in a parking and parking prohibited area via the voice control unit 37. It is also possible to output voice data such as “the designated point is in a parking and parking prohibited area” to the display guide unit 7 for voice guidance. Information indicating that the point received by the user through the designated point receiving unit 32 is determined to be within the parking and stopping prohibited area through both the display using the character data and the voice guidance using the voice data through the display guide unit 7. Can also be notified.

  On the other hand, if the designated parking spot is determined not to be in the parking / parking prohibition area (NO in STEP 802), the spot is not in the parking / parking prohibition area via the display control unit 36. For example, data such as “the specified location is not in the parking and prohibition zone” is displayed, or the user is notified by voice guidance (STEP 804). In addition, when the designated point is not within the parking and parking prohibited area, the present invention includes an aspect in which the user is not notified to that effect.

  In addition, as described above, the parking lot search process in the vicinity of the point can also be performed even when the point simply designated by the user is determined as being in the parking / prohibited zone. This parking lot search process will be described below with reference to the flowchart of FIG.

  First, as in the flowchart of FIG. 8, in STEPs 901 to 903, the designated point receiving unit 32 receives the position information of the point designated by the user through the input unit 9 (STEP 901), The parking / parking prohibition area database is read from the memory 13 from the memory 13, and it is determined whether or not the designated point exists in the read parking / parking prohibition area (STEP 902). If the designated stop point is determined to be within the stop / stop prohibited area by the stop / stop prohibited area determination unit 34 (YES in STEP 902), the point is determined via either the display control unit 36 or the voice control unit 37. Is notified to the user that the vehicle is in the parking and prohibition zone (STEP 903).

  In order to let the user select whether to search for a parking lot in the vicinity of the point in the display guide unit 7 at the same time as notifying the user that the designated point is in a parking and parking prohibited area, for example, A message such as “Do you want to search for and guide the nearest parking lot? (Yes / No)” is displayed (STEP 904). When “Yes” is pressed through the input unit 9 which is a touch panel (YES in STEP 904), whether or not there is a nearest parking lot for the point received by the nearby parking lot search unit 35 by the designated point receiving unit 32. Is searched (STEP 905).

  When the nearest parking lot is searched by the neighborhood parking lot search unit 35 (YES in STEP 905), the nearest parking lot at the point is selected via either the display control unit 36 or the voice control unit 37. The user is notified of the information that there has been (STEP 906).

  In STEP905, when the nearest parking lot search unit 35 has not searched for the nearest parking lot (NO in STEP905), the display control unit 36 displays character data indicating that there is no nearest parking lot. The information is displayed through the guide unit 7 and notified to the user (STEP 907). Instead of displaying that there is no nearest parking lot. It is also possible to provide voice guidance by the voice control unit 37.

  In STEP 902, if the designated parking spot is determined not to be within the parking prohibited zone by the parking prohibited zone determination unit 34 (NO in STEP 902), the point is designated as a parking prohibited zone via the display control unit 36. Information indicating that it is not within, for example, data such as “the designated location is not within the parking and parking prohibited area” is displayed or notified to the user by voice guidance (STEP 908). In addition, when the designated point is not within the parking and parking prohibited area, the present invention includes an aspect in which the user is not notified to that effect.

(B) In addition, the parking lot search process near the destination by the neighborhood parking lot search unit 35 in the above embodiment is performed by the user selection through the input unit 9 when it is determined that the destination is in a parking and parking prohibited area. However, the present invention is not limited to this, and when it is determined that the destination is in the parking / restricted parking area, the neighborhood parking lot search unit 35 automatically detects the vicinity of the destination. A mode of searching for a parking lot is also included.

  That is, in the flowchart of FIG. 5, in the display guide unit 7 of STEP 505, as shown in FIG. 7, the “Nearest parking lot” is selected so that the user can select whether to search for a parking lot near the destination. The display operation such as “Do you want to search and guide? (Yes / No)” is omitted, and the neighborhood parking lot search unit 35 automatically searches for the parking lot near the destination (STEP 506). In the flowchart of FIG. 9 that does not have a navigation operation, the same processing can be performed. In this case, the operation of allowing the user of STEP 904 to select the parking space search process is omitted, and the nearby parking space is automatically set. A parking lot in the vicinity of the designated point is searched by the search unit 35 (STEP 905).

(C) In the above embodiment, a parking and parking prohibited area is described as an example of the area having traffic regulation information. However, the present invention is not limited to this parking and parking prohibited area, and the destination or designated point is Embodiments for determining whether the vehicle is in a prohibited parking area, a prohibited parking area, or other regulatory information area are also included.
