Japanese Patent Laid-Open No. 05-189441

  However, when finding an empty parking space in such a parking lot, it is installed in each parking area, displaying about empty information such as there is no space on the first floor parking space and there is a space on the second floor parking space. The driver was able to judge only from the display of availability. For this reason, after all, it can be judged only by running around the vast hall, arriving at each parking area in the hall and looking at the display there in which parking area there is an empty space. As a result, on the facility side, it is necessary to arrange a guide to make up for the shortage of information display, and the cost is greatly increased. On the other hand, even if there is a driver's request for stopping the facility, the guidance by the guide does not reflect the driver's request.

  An object of the present invention is to provide a parking lot availability information notification system that displays the availability information in a vast parking lot so that it can be understood without arranging a guide and allows the driver to park at a desired position. It is to provide.

A parking area 3P that is vacant in the parking space 3p is detected from the area 3P, and a notification output in which the position of the detected parking area 3P that is vacant in the parking lot 3 is arranged in the passenger compartment of the vehicle 5 is output. Parking lot guidance processing for informing the driver from the unit 53 is executed as shown in FIGS. 3 and 6.

  First, the control unit 51 detects whether or not the vehicle 5 has entered the parking lot 3 of the facility 2 (S1: parking lot entry detecting means). Here, when the communication unit 57 wirelessly receives the entrance passage information wirelessly transmitted by the entrance passage notification unit 3e provided at the entrance 3E of the parking lot 3, the control unit 51 causes the vehicle 5 to park the facility 2. It is determined (detected) that the vehicle has entered the car park 3. Whether or not the vehicle 5 has entered the site including the parking lot 3 of the facility 2 based on the map data stored in the storage unit 56 and the current position information of the vehicle 5 detected by the position detection unit 52 in the car navigation device 50. By detecting this, the approach to the parking lot 3 may be estimated and detected.

  And the control part 51 notifies the parking management apparatus 20 of the start of parking lot guidance, when approaching into the parking lot 3 of the vehicle 2 is detected (S2: guidance start notification means). Here, the parking lot guidance is started by transmitting a guidance information request signal for parking lot guidance from the communication unit 27 (S2: guidance information requesting means, vacancy status requesting means). The guidance information requested here includes parking with a space detected by the parking management device 20 based on the space determination information acquired from the space determination information acquisition unit group 3S (each space determination information acquisition unit 3s) for each area 3P. The free space information indicating the detection result of the area and the map image information of the parking lot used for the guidance display. Here, the map image indicating the positional relationship between each parking area 3P and the vehicle traveling path 3L provided in the vicinity thereof This is image information for display. That is, as shown in FIG. 11, the parking lot guidance of the present embodiment displays a map image of the parking lot and displays a parking area 3P that is empty in the middle. In addition to the situation information, display information that is the base of the parking lot guidance display is also required. Thus, here, the parking management device 20 is notified of the start of parking lot guidance by transmitting a request signal for requesting information for guidance display including such availability information and map image information (S2: guidance information requesting means). To do.

  On the other hand, in the parking management device 20, as shown in FIG. 4, at a predetermined cycle (when a predetermined time elapses), the control unit 21 performs vacancy determination information acquisition unit group 3S for each area 3P (each vacancy determination information acquisition). Vacancy determination information is acquired from the unit 3s) (S20), and based on the acquired vacancy determination information, the vacancy status of each parking area, that is, a vacant parking area is detected, and the vacancy status information as the detection result is Each area is stored in the storage unit 26 in the form shown in FIG. 5 as an example (S21). Then, when the communication unit 27 receives the guidance information request signal (S22: Yes), the control unit 21 wirelessly transmits the availability information read from the storage unit 26 to the requesting vehicle 5 as a reply. Transmit (S23).

  Returning to FIG. When the control unit 51 requests the parking management device 20 for guidance display information including availability information and map image information, the communication unit 57 receives the requested guidance display information (S3: guidance information acquisition means, Free space receiving means). And the control part 51 pinpoints the position in the parking lot 3 of the parking area 3P with vacancy based on the vacancy status information (detection result of a vacant parking area) contained in the received information for guidance display (S4). The result is notified from the notification output units 53 and 54 (S5: empty parking area notification means). Here, the position in the parking lot 3 of the empty parking area 3P is indicated by the screen display on the display unit 53, and the position guidance is performed by voice output.

  Subsequently, the control unit 51 detects whether or not the vehicle 5 has left the parking lot 3 of the facility 2 (S6: parking lot leaving detection means). Here, when the communication unit 57 wirelessly receives the exit passage information wirelessly transmitted by the exit passage notification unit 3f provided at the exit 3F of the parking lot 3, the control unit 51 causes the vehicle 5 to park the facility 2. It is determined (detected) that the vehicle has left the parking lot 3. Whether or not the vehicle 5 has left the site including the parking lot 3 of the facility 2 based on the map data stored in the storage unit 56 and the current position information of the vehicle 5 detected by the position detection unit 52 in the car navigation device 50 By detecting this, the departure from the parking lot 3 may be estimated and detected. When the departure of the vehicle 2 from the parking lot 3 is detected (SS6: Yes), the control unit 51 deletes the acquired guidance display information including the availability information and the map image information (S11), and displays the guidance. (This processing) is terminated.

  Moreover, also when the OFF signal input of the ignition switch 58 is received (S7: Yes), the control part 51 complete | finishes guidance display (this process). In this case, the control unit 51 does not erase the guide display information, and starts the process from S9 based on the remaining guide display information when the ignition is turned on next time. Thereby, the control part 51 can restart the alerting | reporting of the position in the parking lot 3 of the parking area 3P with vacancy based on the newly acquired empty condition information.

  When the departure of the vehicle 2 from the parking lot 3 is not detected (S6: No) and the ignition switch 58 remains ON (S7: No), the position of the vacant parking area 3P in the parking lot 3 It is determined whether or not a predetermined time has elapsed since the notification was started (S5) (S8), and if it has not elapsed, the current notification is continued. On the other hand, when the predetermined time has elapsed (S8: Yes), the control unit 51 updates the availability information in the already obtained information for guidance display (S9, S10: availability information update means).

  That is, the control unit 51 wirelessly transmits a request signal for requesting the latest vacancy status information to the parking management device 20 from the communication unit 57 (S9: vacancy status request means), and then the communication unit 57 requests the latest A reply of the availability information (S25 in FIG. 4) is received (S10: availability reception means). That is, in the parking management device 20, when the communication unit 27 receives the request signal for the availability information (S24: Yes), the control unit 21 reads the request source vehicle 5 from the storage unit 26 as a reply. The vacancy status information is wirelessly transmitted (S25: vacancy status transmission means).

  When the control unit 51 receives the latest vacant state information (the detection result of the vacant parking area) transmitted wirelessly (S10), the control unit 51 again parks the vacant parking area 3P based on the received vacant state information. The position in the parking lot 3 is specified (S4), and the result is notified from the notification output units 53 and 54 (S5: empty parking area notification means). That is, it can be said that the availability information (S10) received here is update information received in order to update the notification content currently being notified.

  However, in the parking lot guidance process according to the present embodiment, when the location of the vacant parking area 3P in the parking lot 3 is notified, the control unit 51 has a vacant parking specified based on the vacancy status information. From the area 3P, a recommended parking area 3P (3Q) that recommends parking is selected on the basis of predetermined parking recommended conditions (S4: recommended parking area selection means), and as shown in FIG. Furthermore, the position display 530P (530Q) of the selected recommended parking area 3P (3Q) out of the free parking area 3P is displayed with emphasis over the remaining parking area 530P with the space ( S5: Empty parking area notification means).

  Here, the control unit 51 selects the nearest parking area 3P closest to the facility 2 as the recommended parking area 3P (3Q) from among the free parking areas 3P as the recommended parking area according to the recommended parking conditions. . However, the recommended parking area 3P (3Q) may be selected as the closest parking area 3P among all the parking areas 3P with vacancies. Among the parking areas 3P, the closest parking area 3P closest to the facility 2 is selected from among the priority parking areas 3P that satisfy a predetermined priority selection condition. Here, the recommended parking area is selected by the process shown in FIG.

  That is, first, the control unit 51 identifies and extracts a parking area 3P having a space from all the parking areas 3P based on the acquired space status information (S50). Taking FIG. 11 as an example, areas A, C, E, F, H, and I are specified and extracted.

  Then, the control unit 51 determines whether or not a priority selection condition is set (S51). Here, the priority selection condition setting screen 530Y as shown in FIG. 10 is displayed on the display unit 53 by the control unit 51, and a predetermined selection operation (here, a touch operation on the operation image 530B) by the user to the operation input unit 55 is performed. ) To set the priority selection condition. The setting may include a conditional priority selection condition for switching the condition contents when a predetermined vehicle situation is detected.

  In the priority selection conditions that can be set here, only when the control unit 51 detects a predetermined vehicle situation, the parking area 3P that satisfies the predetermined condition is set as the priority parking area 3P, and this is not detected. Includes a conditional priority selection condition that the parking area 3P that satisfies the predetermined condition is not set as the priority parking area 3P.

  Here, the control unit 51 determines whether or not the conditional priority selection condition is set (S51), and when it is determined that there is a setting (S51: Yes), a predetermined vehicle situation (here) Vehicle status information for detecting (rainfall / snow) is acquired from the vehicle status acquisition unit 59 (S52), the vehicle status is detected based on the acquired vehicle status information (vehicle status detection means), and the detected vehicle It is determined whether or not the condition satisfies the preconditions of the conditional priority selection condition (S53). If the conditions are satisfied (S53: Yes), it is determined whether or not there is a parking area 3P that satisfies the basic condition of the conditional priority selection condition. If there is (S54: Yes), the parking area 3P that satisfies the condition is picked up (extracted) as the priority parking area 3P (S55).

  More specifically, here there is rain protection on the walking path 3R that leads to the facility 2 in the parking lot 3, so that the parking area 3P adjacent to the walking path 3R from the viewpoint of sun protection, rain and snow protection. Can be set in the priority parking area 3P. However, here, instead of simply setting the parking area 3P close to the walking path 3R as the priority parking area 3P, it is assumed that the parking area 3P is either raining or snowing (rain) (rain path 3R). It is possible to set a conditional priority selection condition in which the parking area 3P close to is set as the priority parking area 3P. The control unit 51 determines whether or not the conditional priority selection condition is set (S51), and if it is determined that the setting is present (S51: Yes), the vehicle that forms the external environment status as the vehicle status information. 5. Weather information for detecting rain / snow in the vicinity is acquired (S52). The vehicle status acquisition unit 59 that acquires weather information may be a raindrop sensor that directly detects rainfall or snowfall on the vehicle 5, or a weather information acquisition unit that obtains weather information around the vehicle 5 through communication with an external weather center. Good. Based on the acquired weather information, the control unit 51 detects rainfall / snowfall around the vehicle 5 (external vehicle environment state detection means), and when such rain / snow is detected (S53: Yes), the conditional priority selection condition is satisfied. It is determined that the precondition is satisfied, and this time, the parking area 3P that satisfies the basic condition of the conditional priority selection condition, that is, the parking area adjacent to (in this case, adjacent) the walking path 3R with sunshade, rain and snow The area 3P is set as the priority parking area 3P, and the presence / absence of the priority parking area 3P in the parking space 3p is specified (S54). Taking FIG. 11 as an example, areas A, C, E, F, and H are specified.

  And the control part 51 picks up (extracts) the priority parking area 3P with the specified empty | vacancy (S55). Taking FIG. 11 as an example, areas A, C, E, F, and H are picked up. However, the priority selection condition is not set (S51: No), the precondition of the conditional priority selection condition is not satisfied (S53: No), the basic condition of the conditional priority selection condition is not satisfied (S54: No), etc. In this case, the control unit 51 picks up (extracts) an empty parking area 3P from all the parking areas 3P (S50). Taking FIG. 11 as an example, areas A, C, E, F, H, and I are picked up.

  Then, the control unit 51 selects, as a recommended parking area 3Q (3P), the closest parking area closest to the facility 2 among the free parking areas 3P picked up at this stage (S57, S58). : Recommended parking area selection method).

  However, in this embodiment, the destination setting in the facility 2 is possible, and when the destination setting is made (S56: Yes), the control unit 51 recommends the recommended parking area 3Q (3P). The closest parking area closest to the in-facility store 2G set as the destination is selected as the recommended parking area 3Q (3P) from the parking area 3P picked up immediately before is selected (S57). . On the other hand, when the destination setting in the facility 2 is not made (S56: No), the control unit 51 selects the parking area 3P picked up immediately before the recommended parking area 3Q (3P) is selected. The closest parking area closest to the entire facility is selected as the recommended parking area 3Q (3P) (S58). When the recommended parking area 3Q (3P) is selected in this manner (S57, S58), the process returns to FIG. 3 (proceeds to S5 in FIG. 3).

  Here, in the destination setting in the facility 2, the control unit 51 displays the destination store setting screen 530X as shown in FIG. 9 on the display unit 53, and the user performs a predetermined selection operation on the operation input unit 55. The destination store 2G in the facility 2 is set by (here, a touch operation on the operation image 530A).

  More specifically, the destination setting process in the facility 2 here is executed after the navigation device 50 completes the operation of setting the destination for route guidance. That is, as shown in FIG. 7, the control unit 51 first determines whether or not the set destination is a complex facility 2 having a plurality of stores 2S therein (S51). If it is not the complex facility 2, this processing ends without setting the destination store. On the other hand, in the case of the complex facility 2, the control unit 51 acquires store information indicating the store 2S in the facility 2 (S52). When this cannot be acquired (S53: No), this processing ends without setting the destination store 2G. On the other hand, if it can be acquired (S53: Yes), the destination store setting screen 530X is displayed (S54), and the user performs a predetermined selection operation on the operation input unit 55 (here, a touch operation on the operation image 530A). (S55: Yes), the store 2S selected by the selection operation is set as the destination store 2G (S56). As shown in FIG. 9, the destination store setting screen 530X here is a screen displaying the names of stores 2S in the facility 2 on the operation images 530A displayed as a list, and touching the operation image 530A. By the operation, the store corresponding to the touched operation image 530A is set as the destination store.

  The destination setting in the facility 2 (S52 to S56) is as shown in FIG. 8, when entering the parking lot 3 of the facility 2, for example, in the same way as S1 in FIG. The entry of the vehicle 5 from 3E may be detected (S51 ′), and may be executed when the entry is detected.

  Here, the screen display of the position of an empty parking area is demonstrated using FIG.

  As shown in FIG. 11, the screen display of the position of the parking area where there is an empty space is displayed on the screen of the display unit 53 by the control unit 51 based on the received map image information. This is done by clearly indicating the position of an empty parking area 3P in a state where the map image 530 of the parking lot 3 showing the positional relationship between the area 3P and the vehicle travel path 3L is displayed. That is, in the map image 530 of the parking lot 3, the area display 530P indicating each parking area 3P is displayed at the corresponding position, and here, the empty information display 530t of the corresponding area 3P is displayed on the area display 530P.

Of the 530P, the display 530P of the area 3P having a vacancy is displayed in a visual state different from the display 530P of the area 3P having no vacancy. Here, on the map image 530, the area display 530P corresponding to the free area 3P is displayed more emphasized than the area display 530P corresponding to the free area 3P. Specifically, here, the display color in the area display 530P is changed, and the display 530P corresponding to the empty area 3P and the display 530P corresponding to the empty area 3P are displayed separately. . Furthermore, the area display 530P corresponding to the empty area 3P is displayed more emphasized than the area display 530P corresponding to the empty area 3P.

  The vacant information display 530t of each parking area 3P here displays not only whether or not there is a vacancy here, but also the number of vacant parking spaces 3p when vacant. Here, the characters “empty” and a number indicating “the number of free parking spaces 3p” are displayed in a simplified manner (for example, “sky 2” etc.). If it is not free, it is displayed that there is no free space. Here, “full” is displayed. The control unit 21 of the parking management device 20 of the present embodiment detects the number of vehicles 5 that have entered each parking area 3P based on the detection result of the vacancy determination information acquisition unit group 3S (the number of entering vehicles is counted). Means), in each parking area 3P, on the basis of the difference between the number of detected vehicles and the number of parking spaces in the parking area 3P, the presence and number of empty parking spaces in the parking area are identified and identified. The result is stored in the storage unit 26 as free space information as shown in FIG. The control part 51 of the vehicle 5 determines the display content of the empty information display 530t of each parking area 3P based on the empty status information received from the parking management apparatus 20, and performs the display with the determined content.

  In addition, on the map image 530 of the parking lot 3 displayed here, a vehicle travel path display 530L indicating the vehicle travel path 3L is displayed. Furthermore, when the one-way road is included in the vehicle travel path 3L, a one-way direction display 530w that clearly indicates the one-way direction is displayed on the vehicle travel path display 530L indicating the one-way path on the map image 530. Is done. In addition, a rain prevention installation area display 530R is also displayed on the map image 530. Furthermore, a host vehicle display 530C indicating the current position and traveling direction of the host vehicle 5P is also displayed.
