It is a flowchart which shows the main control procedures performed in the management system of the commercial vehicle of FIG.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. The vehicle door opening / closing control method and apparatus according to the present embodiment are not particularly limited, but use a sales vehicle V such as a shared vehicle or a shared vehicle to guide a user from a boarding point (departure point) to a drop-off point (destination point). This is preferable for use when the user who has made a reservation for boarding in advance arrives at the boarding point where the user has made a reservation, and when the user gets on the vehicle. As a premise of the business vehicle management system S according to the embodiment described below, the boarding point Pn where an unspecified number of users U can board is a predetermined point, and each boarding point Pn is provided with a short-range communication. It is assumed that the wireless device 2 for transmitting the radio wave of the wireless terminal 2 is arranged, and the user U has the portable terminal device 3 capable of receiving the radio wave from the wireless device 2. The drop-off point may be a predetermined point or an arbitrary point. The commercial vehicle V such as a shared vehicle or a shared vehicle may be an unmanned vehicle or a manned vehicle. Hereinafter, an embodiment of a vehicle door opening / closing control method and apparatus according to the present invention will be described using a business vehicle management system S shown in FIG.

  The wireless device 2 provided at each boarding point Pn is a device, such as WiFi or Bluetooth (registered trademark), for transmitting radio waves for short-range communication in a predetermined band. ON / OFF of transmission of radio waves from each wireless device 2 is controlled by the management unit 11 of the server 1 via a telecommunications network 4 such as the Internet. The management unit 11 can recognize the ID of each wireless device 2 via the telecommunication network 4.

  The mobile terminal 3 owned by the user U is composed of a smart phone, a mobile personal computer, or the like, and has a communication function of transmitting and receiving information via the telecommunication network 4 and receives radio waves from each wireless device 2. At least a radio wave receiving function capable of detecting the intensity of a radio wave received from the wireless device 2 (intensity detecting unit 31), and a GPS signal receiving function. If the radio wave transmitted from the wireless device 2 is WiFi, it is possible to receive the predetermined band radio wave (such as 2.4 GHz or 5 GHz) of the WiFi, and the radio wave transmitted from the wireless device 2 is Bluetooth (registered trademark). For example, it is possible to receive the Bluetooth (registered trademark) predetermined band radio wave (such as 2.4 GHz). Since the GPS signal receiving function is used for recognizing the current approximate position where the user U is located, it is not necessary to always detect a precise position, and it can be omitted.

  Further, the portable terminal 3 is installed with application software for executing user registration and vehicle reservation through the telecommunication network 4 on the server 1 including the vehicle door opening / closing control device of the present embodiment, The user inputs predetermined information using an input unit such as the above and transmits the information to the server 1 or displays the information transmitted from the server 1 on a display.

The server 1 is configured by a computer and software, receives information from the portable terminal 3 owned by the user U, manages the dispatch of the commercial vehicle V, and transmits predetermined information to the portable terminal 3. . Specifically, the management unit 11, the strength acquisition unit 12, the authentication control unit 13,
The vehicle includes a door opening / closing control unit 14 and a database 15.

  The management unit 11 receives registration of the user U in response to a request from the user U. The registration of the user U is performed by transmitting the name of the user U and its attribute information to the management unit 11 by using application software installed in the portable terminal 3 owned by the user U. Is stored in the database 15 of the server 1. As a result, the user U can use the management system S for commercial vehicles in this example.

  The management unit 11 accepts a reservation for using the commercial vehicle V in response to a request from the registered user U. The use reservation procedure of the business vehicle V performed by the user U is performed by first using application software installed in the portable terminal 3 owned by the user U, a boarding point Pn that the user U wants to board, a boarding time, The disembarkation point and the disembarkation time are transmitted to the management unit 11. Upon receiving this, the management unit 11 can arrive at the boarding point Pn at the boarding time desired by the user U from among the plurality of commercial vehicles V, and further, by the boarding time desired by the user U, A search is made to determine whether or not there is a commercial vehicle V that can be transported from Pn to a drop-off point.

  When the hit business vehicle V exists, the ID of the business vehicle V (for example, vehicle type, skin color, number, etc.) and the scheduled arrival time at the boarding point Pn are stored in the portable terminal 3 of the user U. And the scheduled arrival time at the drop-off point. Thereby, the use reservation of the user U is completed, and the user U transmits the ID of the commercial vehicle V transmitted from the management unit 11 (for example, vehicle type, outer panel color, number, and the like) and the boarding point Pn. By displaying the estimated arrival time and the estimated arrival time at the drop-off point on the display, it is possible to confirm the completion of the use reservation.

  When the use reservation is completed, the management unit 11 determines the user ID and the attribute information, the boarding point Pn, the boarding time, the boarding point, and the boarding time for the commercial vehicle V that meets the conditions. The commercial vehicle V that has received the information stores the information in its own travel route plan. When there is no commercial vehicle V that satisfies the condition desired by the user U among the plurality of commercial vehicles V, the management unit 11 transmits the fact to the mobile terminal 3 of the user U. Or an alternative condition may be presented to obtain the approval of the user U. In addition, the management unit 11 receives the disembarkation information transmitted from the commercial vehicle V or the disembarkation information transmitted from the portable terminal 3 of the user U to notify that the user U has disembarked at the disembarkation point, and executes a charging process and the like. .

  When the mobile terminal 3 receives a radio wave transmitted from the wireless device 2 installed at a specific boarding point Pn, the strength acquisition unit 12 detects the reception detected by the strength detection unit 31 of the mobile terminal 3. The radio wave intensity data is acquired from the portable terminal 3 via the telecommunication network 4. Further, when the commercial vehicle V receives a radio wave transmitted from the wireless device 2 installed at a specific boarding point Pn, the intensity of the received radio wave detected by the intensity detecting unit 51 of the commercial vehicle V is determined. Data is acquired from the commercial vehicle V via the telecommunication network 4.

  In the management system S for commercial vehicles shown in FIG. 1, the strength detection unit 31 is provided in the portable terminal 3, the strength detection unit 51 is provided in the business vehicle V, and the strength detection unit 31 and the strength are provided in the server 1. Although the strength acquisition unit 12 of the data of the intensity of the received radio wave detected by the detection unit 51 is provided, the server 1 is provided with the strength detection unit 31 and / or the strength detection unit 51 instead of the strength acquisition unit 12. When the portable terminal 3 and / or the commercial vehicle V receive a radio wave transmitted from the wireless device 2 installed at a specific boarding point Pn, the received radio wave is transmitted to the server via the telecommunication network 4. The server 1 may detect the intensity of the received radio wave by taking it into the first intensity detector 31 and / or the first intensity detector 51.

  The radio wave for short-range communication transmitted from the wireless device 2 is correlated with the distance L from the wireless device 2. FIG. 2 is a diagram showing the wireless device 2 and the portable terminal device 3 owned by the user U arranged at a specific boarding point Pn in the business vehicle management system S. The radio field intensity detected when the user U is at the distance L1 from the boarding point Pn and the radio field intensity detected when the user U is at the distance L2 (<L1) from the boarding point Pn are the distance L2 ( The radio wave intensity detected when the user is in <L1) becomes stronger in correlation with the distance. This relationship also applies to the relationship between the radio wave intensity detected by the intensity detection unit 51 provided on the commercial vehicle V and the distance from the boarding point Pn to the commercial vehicle V.

  FIG. 3 shows the relationship between the radio wave intensity and time detected by the intensity detection unit 31 of the portable terminal 3 owned by the user U when the user U of FIG. 2 approaches and passes through the boarding point Pn. FIG. As shown in FIG. 3, at times t <b> 1 to t <b> 2, the radio wave intensity detected by the intensity detection unit 31 of the portable terminal 3 owned by the user U gradually increases with time, so that the user U moves to the boarding point Pn. It is recognized that it is approaching. Conversely, during the period from time t3 to t4, the radio wave intensity detected by the intensity detection unit 31 of the portable terminal 3 owned by the user U gradually decreases with time, so that the user U is moving away from the boarding point Pn. Is recognized. Then, it is recognized that the user U is near the boarding point Pn during the time t2 to t3 that exceeds the preset radio field intensity threshold. This also applies to the relationship between the radio wave intensity detected by the intensity detection unit 51 provided on the commercial vehicle V and the distance from the boarding point Pn to the commercial vehicle V. Since the radio wave intensity correlates with the distance, the walking speed of the user U can be predicted by differentiating the change in the radio wave intensity with respect to time.

  When using the WiFi radio wave for the wireless device 2, reception is possible within a range of 100 to 200 m when there is no obstacle, and when using the Bluetooth (registered trademark) radio wave for the wireless device 2, Can be received up to a range of 10 m when there is no obstacle, the threshold of the radio field intensity set here is, for example, within 0 to 100 m from the boarding point Pn when the WiFi radio wave is used for the wireless device 2. Can be set to the strength of the radio wave detected by the strength detection unit 31 or the strength detection unit 51 when the vehicle is in the vehicle. When the distance is within 10 m, the radio wave intensity detected by the intensity detector 31 or the intensity detector 51 can be set.

  When the wireless device 2 is arranged at each of the plurality of boarding points Pn, the radio wave intensity acquired by the intensity acquiring unit 12 of the server 1 indicates that the user U has It is not possible to identify whether it is receiving the radio wave from 2 or not. FIG. 4 is a diagram (upper diagram) and a graph showing the relationship between radio wave intensity and time detected by the intensity detector 31 of the portable terminal 3 when the user U passes through a plurality of boarding points P1 to P4 (FIG. 4). The figure below). As shown in the upper diagram of FIG. 4, four boarding points P1 to P4 are set in a part of the travel route Rt, and radio devices 21 to 24 are arranged at each of the boarding points P1 to P4. I do. Assuming that the user U has walked along the travel route Rt from the boarding point P1 to the boarding point P2, the boarding point P3, and the boarding point P4, the strength detection unit 31 of the portable terminal 3 carried by the user U detects the user U. The intensity of the radio wave changes as shown in the graph in the lower part of FIG.

  However, as described above, the peak of the radio wave intensity acquired by the intensity acquisition unit 12 of the server 1 shown in the lower diagram of FIG. 4 cannot be identified to which boarding point Pn the user U is near. Therefore, the current position of the user U is roughly grasped using the GPS signal receiving function of the portable terminal device 3, and the management unit 11 turns on (or off) the wireless device 2 at the boarding point Pn closest to the current position. By doing so, a change in radio field intensity is detected.

  For example, assuming that the current position of the user U is a position close to the boarding point P2 using the GPS signal receiving function of the portable terminal 3, only the wireless device 22 at the boarding point P2 is turned ON, and the other boarding points are turned on. The wireless devices 21, 23, and 24 of P1, P3, and P4 are turned off, and in this case, the accurate position of the user U is grasped from the radio wave intensity detected by the intensity detection unit 31 of the portable terminal device 3. Further, assuming that the current position of the user U is a position close to either the boarding point P2 or P3 using the GPS signal receiving function of the portable terminal 3, the wireless device 22 at the boarding point P2 or the wireless device 22 at the boarding point P3 Only one of the radios 23 is turned on, and the radios at the other boarding points are turned off. In this case, the current position of the user U is determined by the radio wave intensity detected by the intensity detection unit 31 of the portable terminal 3. It is determined which position is closer to P2 or P3. It should be noted that the radios 21 to 24 at each of the boarding points P1 to P4 are always turned on, and a scan for sequentially turning off the radios 21 to 24 is executed in order to grasp the accurate current position of the user U, The change of the radio wave intensity to zero may be detected.

  Incidentally, in the scene shown in FIG. 4, since the walking speed of the user U can be predicted from the detected radio wave intensity, if the boarding point reserved by the user U is P4, the walking speed reaching the boarding points P1 to P3 , The time of arrival at the boarding point P4 can also be predicted. The above relationship shown in FIG. 4 can be said to be the same for the radio wave intensity detected by the intensity detection unit 51 of the commercial vehicle V.

  Returning to FIG. 1, the authentication control unit 13 performs authentication of the user U based on the radio wave intensity obtained by the intensity detection unit 31 acquired by the intensity acquisition unit 12. Specifically, the authentication control unit 13 authenticates that the user U has arrived at the boarding point Pn when the radio field intensity is larger than the predetermined threshold shown in FIG. In the business vehicle management system S of this example, the arrival of the user U who has completed use reservation in advance at the reserved boarding point Pn is determined not by the GPS signal reception function but by the wireless device 2 and the portable terminal 3. Is performed based on the reception status of the radio wave during the period (specifically, the radio wave intensity). Note that the GPS signal receiving function of the mobile terminal 3 may be used for auxiliary use such as checking the approximate position of the user U. When the authentication control unit 13 authenticates that the reserved user U has arrived at the reserved boarding point Pn, the authentication control unit 13 transmits the fact to the management unit 11.

  Similarly, the authentication control unit 13 recognizes the arrival of the commercial vehicle V at the boarding point Pn based on the radio field intensity obtained by the intensity detection unit 51 acquired by the intensity acquisition unit 12. Specifically, the authentication control unit 13 recognizes that the commercial vehicle V has arrived at the boarding point Pn when the radio wave intensity is larger than the predetermined threshold shown in FIG. In the sales vehicle management system S of this example, the arrival of the previously reserved sales vehicle V at the reserved boarding point Pn is determined not by the GPS signal reception function but by the wireless device 2 and the sales vehicle. This is performed based on the reception status of the radio wave with V (specifically, the radio wave intensity). Note that the GPS signal receiving function of the commercial vehicle V may be used for auxiliary use such as confirming the approximate position of the commercial vehicle V. When confirming that the business vehicle V reserved for use has arrived at the reserved boarding point Pn, the authentication control unit 13 transmits the fact to the management unit 11.

  The commercial vehicle V includes a door opening / closing mechanism 52 that automatically opens and closes the revolving door D on which the user U gets on or off. The pivoting door D may be either a front door or a rear door, and may be applied to a gull wing type door or a butterfly door that pivots vertically, in addition to a door that pivots horizontally. In short, the present invention is preferably applied to a vehicle including a door of a type in which the opening and closing range of the door extends outside the horizontal projection plane of the vehicle.

  The detailed structure of the door opening / closing mechanism 52 is not particularly limited. Opening and closing mechanism. The door opening / closing mechanism 52 includes an actuator that operates such a door latch mechanism, an actuator that operates a lock mechanism, and an actuator that opens and closes the door D itself. Then, when the user U gets on or gets off the vehicle, upon receiving a door opening signal to open the door from a door opening / closing control unit 14 to be described later, the door lock mechanism is unlocked, the door latch mechanism is opened, and the door latch mechanism is opened. Control for opening D is executed. Further, when the user U gets on or gets off, when receiving a door closing signal from the door opening / closing control unit 14 to close the door, the door D is closed, the door latch mechanism is engaged, and the door lock mechanism is locked. Control is executed. The door opening / closing mechanism 52 may open and close the door D continuously (at a stretch) from the fully closed state to the fully open state. However, as shown in FIG. The opening and closing of the door D may be controlled in multiple stages, such as opening and closing to a state.

  The commercial vehicle V includes an in-vehicle device 50 composed of a computer or the like. The in-vehicle device 50 has a communication function capable of transmitting and receiving information to and from the server 1 via the telecommunication network 4, and A radio wave receiving function capable of receiving radio waves from each wireless device 2 installed in Pn, an intensity detecting function (intensity detecting unit 51) capable of detecting the intensity of the radio wave received from the wireless device 2, a GPS And a signal receiving function. If the radio wave transmitted from the wireless device 2 is WiFi, it is possible to receive the predetermined band radio wave (such as 2.4 GHz or 5 GHz) of the WiFi, and the radio wave transmitted from the wireless device 2 is Bluetooth (registered trademark). For example, it is possible to receive the Bluetooth (registered trademark) predetermined band radio wave (such as 2.4 GHz). Since the GPS signal receiving function is used for recognizing the current approximate position of the commercial vehicle V, it is not necessary to always detect a precise position, and it can be omitted.

  Note that the intensity detection unit 51 provided in the commercial vehicle V outputs the received radio wave intensity to the intensity acquisition unit 12 of the server 1 in order to detect the distance between the commercial vehicle V and the boarding point Pn. Therefore, as shown in FIG. 5, it is known that the commercial vehicle V stops within the frame of the preset stop position Px at the boarding point Pn, including the stopping posture (the traveling direction at the time of stopping). In this case (in other words, when the stop position of the commercial vehicle V at the boarding point Pn is determined), the rotation range R of the door D is also known. Therefore, by storing in the database 15 the position information (for example, the latitude / longitude or the distance from the wireless device 2) of the turning range R of the door D of the commercial vehicle V at each boarding point Pn, It may be omitted.

  The server 1 includes a door opening / closing control unit 14. FIG. 5 is a diagram illustrating the business vehicle management system S according to the present embodiment, in which the wireless device 2 disposed at the boarding point Pn, the portable terminal device 3 owned by the user U, and the rotation of the door D of the business vehicle V are shown. 6 is a plan view showing a range R. FIG. The door opening / closing control unit 14 detects the radio wave intensity acquired by the intensity acquisition unit 12, that is, the distance L 3 of the user U from the wireless device 2 based on the radio wave intensity detected by the intensity detection unit 31 and the intensity detection unit 51. From the distance L4 of the commercial vehicle V from the wireless device 2 based on the obtained radio field intensity, it is determined whether or not the user U enters the turning range R of the door D of the commercial vehicle V arriving at the boarding point Pn. When it is determined that the user U does not enter the rotation range of the door D, the control unit controls the door opening / closing mechanism 52 to open the door D.

  In addition, as shown in FIG. 5, the stop of the commercial vehicle V within the frame of the preset stop position Px at the boarding point Pn includes the stop posture (the traveling direction at the time of stop). If it is known, the door opening / closing control unit 14 determines the distance L3 of the user U from the wireless device 2 based on the radio wave intensity acquired by the intensity acquisition unit 12, that is, the radio wave intensity detected by the intensity detection unit 31. From the known turning range R of the door D of the commercial vehicle V stored in the database 15, whether the user U enters the turning range R of the door D of the commercial vehicle V arriving at the boarding point Pn. It may be determined whether or not.

  When the user U determines that the user U does not enter the rotation range R of the door D, the door opening / closing control unit 14 executes control to open the door D by controlling the door opening / closing mechanism 52. The door D may be opened and closed in multiple stages, such as opening and closing continuously from a fully closed state to a fully open state, or opening and closing from a fully closed state to a fully open state through a half open state as shown in FIG. Is also good.

  Returning to FIG. 1, the commercial vehicle V includes a notification unit 53 including a speaker and a display. When the user U determines that the user U enters the rotation range R of the door D at the current standby position at the boarding point Pn, the notifying unit 53 outputs a sound, a buzzer sound, or a display indicating that the user U may interfere with the door D. The user U is notified by, for example,. In addition to or in addition to this notification, the notification unit 53 notifies a recommended standby position at the boarding point Pn. For example, when it is determined that the user U enters the turning range R of the door D at the current standby position, the user U is notified with a voice such as “Please wait diagonally behind the right rear door”.

  In the embodiment illustrated in FIG. 1, the notification unit 53 is provided in the commercial vehicle V. However, the notification unit 53 may be provided in the portable terminal 3 instead or in addition to this.

  Next, the operation of the sales vehicle management system S of this example will be described. FIG. 6 is a flowchart illustrating a main control procedure executed by the sales vehicle management system S of the present example. First, in step S1 of FIG. 6, the management unit 11 of the server 1 acquires the reservation status of the user U. As described above, the reservation status of the user U is first determined by using application software installed in the portable terminal 3 owned by the user U, the boarding point Pn where the user U wants to get on, the boarding time, The point and the getting-off time are transmitted to the management unit 11. Upon receiving this, the management unit 11 can arrive at the boarding point Pn at the boarding time desired by the user U from among the plurality of commercial vehicles V, and further, by the boarding time desired by the user U, A search is made to determine whether or not there is a commercial vehicle V that can be transported from Pn to a drop-off point.

  When the hit business vehicle V exists, the ID of the business vehicle V (for example, vehicle type, skin color, number, etc.) and the scheduled arrival time at the boarding point Pn are stored in the portable terminal 3 of the user U. And the scheduled arrival time at the drop-off point. Thereby, the use reservation of the user U is completed, and the user U transmits the ID of the commercial vehicle V transmitted from the management unit 11 (for example, vehicle type, outer panel color, number, and the like) and the boarding point Pn. By displaying the estimated arrival time and the estimated arrival time at the drop-off point on the display, it is possible to confirm the completion of the use reservation. When the use reservation is completed, the management unit 11 determines the user ID and the attribute information, the boarding point Pn, the boarding time, the boarding point, and the boarding time for the commercial vehicle V that meets the conditions. The commercial vehicle V that has received the information stores the information in its own travel route plan.

  In step S2, the position information of the user U and the business vehicle V is detected. The detection of the position information of the user U and the commercial vehicle V is performed by the GPS signal receiving function of the portable terminal 3 owned by the user U and the GPS signal receiving function of the vehicle-mounted device of the commercial vehicle V. By transmitting the information to the server 1 via the telecommunications network 4, the management unit 11 grasps the approximate current positions of the user U and the commercial vehicle V.

  In step S3, based on the current positions of the user U and the commercial vehicle V detected in step S2, the boarding point Pn reserved by the user U, and the boarding time, the wireless device located at the boarding point Pn 2 and transmission / reception of radio waves between the portable terminal 3 and the commercial vehicle V owned by the user U are started. Here, on the condition that the current position of the user U is within a predetermined distance from the boarding point Pn reserved by the user U from a predetermined time (for example, 15 minutes before) the boarding time reserved by the user U, A command signal for turning on the wireless device 2 is output from the management unit 11 to start transmitting radio waves. In addition, regardless of the current position of the user U detected in step S2, the boarding point Pn reserved by the user U, and the boarding time, the radio device 2 may always transmit radio waves.

  In step S4, the authentication control unit 13 authenticates that the user U has arrived at the boarding point Pn when the radio wave intensity of the mobile terminal 3 acquired by the intensity acquisition unit 12 is larger than a predetermined threshold shown in FIG. It outputs information indicating that it has arrived at the management unit 11. Similarly, the authentication control unit 13 authenticates that the commercial vehicle V has arrived at the boarding point Pn when the radio wave intensity of the commercial vehicle V acquired by the intensity acquiring unit 12 is larger than the predetermined threshold shown in FIG. , And outputs information indicating that it has arrived at the management unit 11. In addition, the predetermined threshold value shown in FIG. 3 may be set to a different value between the portable terminal 3 and the commercial vehicle V.

  In step S5, the door opening / closing control unit 14 detects the distance L3 of the user U from the wireless device 2 based on the radio wave intensity detected by the intensity detection unit 31, and the intensity detection unit 51, as shown in FIG. From the distance L4 of the commercial vehicle V from the wireless device 2 based on the received radio wave intensity, it is determined whether or not the user U enters the turning range R of the door D of the commercial vehicle V arriving at the boarding point Pn. Here, the distance L4 of the commercial vehicle V from the wireless device 2 based on the radio wave intensity detected by the intensity detecting unit 51 is strictly defined by the intensity detecting unit 51 of the commercial vehicle V from the wireless device 2 (actually, the radio wave receiving ), The rotation range R of the door D of the commercial vehicle V is converted to the distance L4 because the relationship with the position of the intensity detection unit 51 (actually, the radio wave reception unit) is known. Thus, it can be determined whether or not the user U enters the rotation range R of the door D.

  When the user U does not enter the turning range R of the door D of the commercial vehicle V arriving at the boarding point Pn, that is, when the user U is at a standby position where the user D does not interfere even when the door D is opened, the door opening / closing control unit 14 outputs an open signal to the door opening / closing mechanism 52. Upon receiving this, the door opening / closing mechanism 52 unlocks the door lock mechanism, opens the door latch mechanism, and opens the door D. Thereby, the user U can get on. When the user U gets on, the door opening / closing mechanism 52 closes the door D.

  On the other hand, when the user U enters the turning range R of the door D of the commercial vehicle V arriving at the boarding point Pn, that is, when the user D is in a standby position where opening the door D may interfere with the user U. The door opening / closing control unit 14 outputs a notification signal to the notification unit 53 without outputting an opening signal to the door opening / closing mechanism 52, and indicates that there is a possibility of interference with the door D by voice, buzzer sound, display, or the like. Notify the user U. In addition to or in addition to this notification, the notification unit 53 may notify a recommended standby position at the boarding point Pn based on the radio wave intensity detected by the intensity detection unit 31. For example, when it is determined that the user U enters the turning range R of the door D at the current standby position, the user U is notified with a voice such as “Please wait diagonally behind the right rear door”. This notification of the recommended position may be performed not only when the user U enters the turning range R of the door D of the commercial vehicle V arriving at the boarding point Pn, but also before determining whether to enter. .

  Further, in addition to or instead of the notification by the notification unit 53, when the user U is at the standby position where there is a risk of interfering when the door D is opened, the door opening / closing control unit 14, as shown in FIG. The door D may be opened from the fully-closed state to the half-open state, and the user D may be prompted to move to a position that does not interfere with the door D by the half-opening operation of the door D, and then may be controlled to open to the fully-open state. This multi-stage opening control of the door D is executed not only when the user U enters the turning range R of the door D of the commercial vehicle V arriving at the boarding point Pn, but also before determining whether or not to enter. May be.

  Returning to FIG. 6, since the authentication of the user U (arrival to the boarding point Pn) and the opening / closing operation of the door are performed by the above-described processing, the authentication state and the riding of the user U are sent to the management unit 11 in step 6. Output. Here, the management unit 11 transmits the authentication status and the ride of the user U to the commercial vehicle V. In step S7, when the user U gets off at the destination drop-off point, the management unit 11 informs the user U of getting off at the drop-off point transmitted from the commercial vehicle V or the mobile information of the user U. It receives the disembarkation information transmitted from the terminal device 3 and executes a charging process and the like.

  As described above, according to the business vehicle management system S of the present example, the radio wave from the wireless device 2 that is arranged at the boarding point Pn of the business vehicle V and transmits radio waves, The radio wave intensity of the radio wave received by the terminal 3 is detected, and based on the detected radio wave intensity, it is determined whether or not the user U enters the turning range R of the door D of the commercial vehicle V arriving at the boarding point Pn. When it is determined that the user U does not enter the rotation range R of the door D, control for opening the door D is executed. Since the radio wave intensity of the radio wave from the wireless device 2 received by the portable terminal 3 carried by the user U is correlated with the distance L from the boarding point Pn, the distance of the user U from the boarding point Pn can be detected. As a result, interference between the user U and the door D can be prevented. In addition, radio waves for short-range communication such as WiFi and Bluetooth (registered trademark) are less likely to have obstacles than GPS signals, so that interference between the user U and the door D can be more reliably prevented. Can be.

  Further, according to the commercial vehicle management system S of this example, when the stop position of the commercial vehicle V is set at the predetermined position of the boarding point Pn, the turning range R of the door D becomes known, and If the information is stored in the database 15, it can be more easily determined from the distance of the user U from the boarding point Pn whether the user U enters the turning range R of the door D.

  Further, according to the commercial vehicle management system S of this example, the radio wave from the wireless device 2 is received by the commercial vehicle V, the radio wave intensity of the received radio wave is detected by the intensity detecting section 51, and the detected radio wave is detected. Since the stop position at the boarding point Pn of the commercial vehicle V is detected based on the strength, it is determined whether the user U enters the turning range R of the door D even if the stop position at the boarding point Pn is not determined. Can be determined.

  Further, according to the sales vehicle management system S of the present example, when the user U determines that the user U enters the rotation range R of the door D, the notification unit 53 notifies the user U to that effect. It is urged to move from the current position, so that interference between the user U and the door D can be prevented.

  Further, according to the sales vehicle management system S of this example, the notification unit 53 notifies the user U of the recommended standby position based on the radio wave intensity detected by the intensity detection unit 31. The notification can prevent interference between the user U and the door D.

  Further, according to the sales vehicle management system S of this example, since the pivotable door D is opened in multiple stages according to the radio wave intensity detected by the intensity detection unit 31, the user U can move from the current position. And the interference between the user U and the door D can be prevented.

  The wireless device 2 corresponds to the wireless device according to the present invention, the mobile terminal 3 corresponds to the mobile terminal according to the present invention, and the intensity detection unit 31 and the intensity acquisition unit 12 perform the first detection according to the present invention. The intensity detection unit 51 and the intensity acquisition unit 12 correspond to a second detector according to the present invention, and the door opening / closing control unit 14 corresponds to a controller according to the present invention.
