Description

  The present invention relates to the technical field of a management device that manages vehicles in a parking lot.

  As an apparatus of this type, for example, an apparatus has been proposed that causes the vehicle to travel automatically so that the parked vehicle arrives at the boarding place by the scheduled departure time designated by the user (see Patent Document 1). Alternatively, a device has been proposed that generates a path from the parking space to the pickup position to determine the movement start time of the vehicle so that the vehicle parked in the parking space arrives at the pickup position just enough (patent Reference 2).

JP, 2015-176468, A International Publication No. 2015/062769

  For example, in the technology described in Patent Document 1, when a plurality of users specify a scheduled departure time within the determination time difference (that is, a plurality of users desire to leave the vehicle at times that approximate each other), The user's vehicle relatively close to the boarding place is moved to arrive at the boarding place earlier than the user's vehicle relatively far from the boarding place.

  However, the technology described in Patent Document 1 is premised on the user arriving at the boarding place at the scheduled departure time, and when the user does not act as scheduled (for example, the user gets on the board with a considerable delay from the scheduled departure time) It does not consider about arrival to a place etc.). The technique described in Patent Document 2 does not consider this point.

  The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a management apparatus capable of carrying out an appropriate leaving of a parked vehicle.

  A management apparatus according to an aspect of the present invention is a management apparatus for carrying out leaving of a vehicle from a parking lot by causing the vehicle to self-propelled, and is a predetermined time before the leaving time designated by the user of the vehicle Or, when there is an exit instruction from the user, an acquisition means for acquiring the current position of the user, and an arrival time of the user at the planned vehicle boarding position based on the acquired current position. And adjusting means for adjusting the leaving time of the vehicle in consideration of the estimated arrival time.

  An embodiment according to a management apparatus will be described with reference to FIGS. 1 to 6. In the following embodiment, a "parking lot management device" is mentioned as an example of a management device.

(Overview)
First, an outline of a parking lot in which a parking lot management device according to the embodiment is installed will be described with reference to FIG. FIG. 1 is a view showing an outline of a parking lot according to the embodiment.

  In FIG. 1, the user of the vehicle gets off at the off site of the parking lot. At the time of storage of the vehicle, the parking lot management device transmits an instruction to park the vehicle in a predetermined parking space (for example, a parking space indicated by a thick frame in FIG. 1). The vehicle having received the instruction enters the parking lot through the storage gate, for example, by the automatic travel function, and parks in a predetermined parking space. At the time of leaving the vehicle, the parking lot management device transmits an instruction to move to the boarding place to the vehicle to be released. The vehicle having received the instruction moves from inside the parking lot to the boarding place through the exit gate, for example, by an automatic travel function. If there is no empty space at the boarding place, the vehicle to be delivered stands by in the waiting space near the delivery gate.

(Constitution)
Next, the configuration of the parking lot management device will be described with reference to FIG. FIG. 2 is a block diagram showing the configuration of the parking lot apparatus according to the embodiment.

  In FIG. 2, the parking lot management device 10 includes a communication unit 11, a monitoring unit 12, a parking lot database (DB) 13, a storage instruction unit 14, a delivery instruction unit 15, and a delivery determination unit 16. The monitoring unit 12 monitors, for example, the vehicle condition and the like in the parking lot, the getting-off place and the getting-in place by a camera, an optical sensor, or the like. The parking lot database 13 stores, for example, the number of parking spaces, the position (coordinates) of each parking space, traveling route information, information concerning the past utilization status, and the like. The storage instruction unit 14, the delivery instruction unit 15, and the delivery determination unit 16 will be described later.

  A vehicle 20 targeted by a parking lot (see FIG. 1) in which the parking lot management device 10 is installed includes a communication unit 21 and an ECU (Electronic Control Unit) 22. The ECU 22 has, for example, a host vehicle peripheral monitoring function, a parking position searching function, a travel route generating function, an automatic driving function, and an automatic parking function. About these functions, since it is realizable by the existing art, explanation about the details is omitted.

  The user terminal 30 held by the user of the vehicle 20 includes a communication unit 31, an HMI (Human Machine Interface) 32, and a position detection unit 33. The user terminal 30 can execute an instruction related to parking of the vehicle 20 (for example, a delivery instruction) and display of information related to a parking space of the vehicle 20. The position detection unit 33 detects the position of the user terminal 30 (that is, the position of the user). The user terminal 30 may be a dedicated terminal, or may be a terminal realized by installing a dedicated application on, for example, a smartphone.

(Operation of parking lot management device)
Next, the operation of the parking lot management device 10 will be described with reference to FIGS. 3 to 6. FIG. 3 is a flowchart showing the warehousing process according to the embodiment. FIG. 4 is a flowchart showing the delivery process according to the embodiment. FIG. 5 is a flowchart showing the delivery process determination according to the embodiment. FIG. 6 is a conceptual diagram showing an example of dividing the distance between the current position of the user and the parking lot.

1. In the warehousing process FIG. 3, first, when the user of the vehicle 20 activates the parking system at the getting-off place (see FIG. 1), the vehicle 20 and the parking lot management apparatus 10 can communicate with each other wirelessly (step S121). ). Here, activation of the parking system may be performed by the user operating a predetermined switch or the like (not shown) provided on the vehicle 20, or may be performed via the user terminal 30. The parking system is a concept including, for example, an own vehicle peripheral monitoring function, a parking position searching function, a travel route generating function, an automatic driving function, and an automatic parking function (see FIG. 2). These functions are activated when the parking system is activated.

  After communication with the vehicle 20 is enabled, the storage instruction unit 14 of the parking lot management device 10 can store the vehicle 20 based on the output of the monitoring unit 12 (for example, information indicating the vehicle status etc. in the parking lot). It is determined whether or not. Then, the storage instruction unit 14 transmits the determination result as the storage availability information to the vehicle 20 (step S111). The ECU 22 of the vehicle 20 acquires the storage availability information (step S122), and notifies the user of information (for example, "available for storage", "full", etc.) according to the storage availability information.

  In FIG. 1, for the sake of convenience, the getting-off place is adjacent to the parking lot, but the getting-off place may be provided relatively far from the parking lot. By the storage availability information being transmitted to the vehicle 20, the user can know whether or not the parking lot is available.

  If the storage availability information indicates that the vehicle 20 can not be stored in the parking lot (that is, the vehicle is full), then it is left to the user's judgment (for example, the vehicle 20 moves to use another parking lot) Or wait at the unloading site until it can be received).

  Here, assuming that the storage availability information indicates that the vehicle 20 can be stored in the parking lot, the storage processing shown in FIG. 3 will be described. After the step S122, the leaving time set by the user is acquired (steps S112 and S123).

  At this time, when the user sets the leaving time via an input device or the like (not shown) provided to the vehicle 20, the ECU 22 of the vehicle 20 acquires the set leaving time and stores it in, for example, a memory or the like. Do. The ECU 22 further transmits a signal indicating the leaving time to the parking lot management device 10 via the communication unit 21. The storage instruction unit 14 of the parking lot management device 10 that has received the signal associates the leaving time indicated by the signal with, for example, the unique information indicating the vehicle 20, the information indicating the parking place of the vehicle 20, etc. Remember to Alternatively, when the user sets the leaving time via the HMI 32 of the user terminal 30, a signal indicating the leaving time is transmitted to the parking lot management device 10 and the vehicle 20 via the communication unit 31.

  Thereafter, the storage instruction unit 14 of the parking lot management device 10 refers to, for example, the parking place of the vehicle 20 and the getting-off place to the parking place with reference to the position of the parking space and traveling route information stored in the parking lot DB13. A travel route is determined, and a signal indicating the determined parking place and travel route is transmitted to the vehicle 20 (step S113).

  The ECU 22 of the vehicle 20 obtains a signal indicating the parking place and the travel route (step S124). After the user dismounts from the vehicle 20, the ECU 22 refers to the travel route indicated by the acquired signal, for example, considering the obstacle around the vehicle 20 detected by the vehicle surroundings monitoring function, etc. The generation function generates a travel route on which the vehicle 20 should actually travel. Then, the ECU 22 controls, for example, an engine, a motor, various actuators, and the like so that the vehicle 20 travels along the generated travel route by the automatic driving function. After the vehicle 20 moves to the vicinity of the parking place indicated by the acquired signal through the warehousing gate, the ECU 22 detects the parking place (for example, a white line indicating a parking space or the like) by the parking position search function. The parking function parks the vehicle 20 at a parking place. (Step S125).

  Thereafter, the ECU 22 puts the vehicle 20 in the standby mode (step S126). Here, the “standby mode” is a state in which energy consumption is suppressed while enabling communication between the vehicle 20 and the parking lot management device 10, for example.

  In addition, the process of the said step S112 and S123 (namely, acquisition and storage of leaving time) may be abbreviate | omitted. That is, the user does not have to set the delivery time at the time of storage. In this case, the leaving time may be set via the user terminal 30 after parking of the vehicle 20 is completed, or a signal indicating a leaving instruction from the user terminal 30 at a timing when the user wishes to leave the vehicle 20 It may be transmitted to the parking lot management device 10.

2. Delivery Process In FIG. 4, the delivery instruction unit 15 of the parking lot management device 10 first determines whether it is a predetermined time before the delivery time set for the vehicle 20 (step S211). Here, the “predetermined time” is set, for example, in consideration of the time required for the movement from the parking place of the vehicle 20 to the boarding place (see FIG. 1).

  If it is determined in step S211 that the predetermined time before the set delivery time is before (step S211: Yes), the delivery instruction unit 15 performs the process of step S213 described later. On the other hand, if it is determined in step S211 that the time is not a predetermined time before the set exit time (step S211: No), the exit instruction unit 15 determines whether there is an exit instruction of the vehicle 20 (Step S212).

  If it is determined in step S212 that there is no delivery instruction (for example, no signal indicating the delivery instruction has been received) (step S212: No), the delivery instruction unit 15 performs the first predetermined period (for example, several tens of millimeters) After the elapse of seconds to several hundreds of milliseconds, the determination in step S211 is performed again. On the other hand, when it is determined in the determination of step S212 that there is an exit instruction (step S212: Yes), the exit determination unit 16 performs an exit determination process to determine whether the vehicle 20 is actually exited (step S213).

  Here, the delivery determination processing will be specifically described with reference to the flowchart of FIG. In FIG. 5, the delivery determination unit 16 acquires the current position of the user of the vehicle 20 by receiving a signal indicating the position detected by the position detection unit 33 of the user terminal 30 (step S301). Next, the delivery determination unit 16 estimates the arrival time of the user at the boarding place based on the distance between the current position acquired by the process of step S301 and the boarding place (step S302).

  When the arrival determination unit 16 estimates the arrival time, in addition to the distance between the current position and the boarding place, for example, the possibility of the user using the transportation means, holidays, holidays, time zones, etc. are also considered. . The arrival time is, for example, as shown in FIG. 6, (i) when the user arrives at the boarding place within a few minutes (case A), (ii) the user arrives at the boarding place within several minutes to several hours In the case (Case B), (iii) If the user does not reach half a day (or several hours or more) and does not arrive at the boarding place (Case C), it is estimated with an accuracy that can be determined. .

  When the arrival time estimated by the process of step S302 is within several minutes from the current time (step S303: within several minutes), the delivery determination unit 16 determines that the delivery of the vehicle 20 is to be performed (step S304). Subsequently, the delivery determination unit 16 transmits a signal indicating the immediate delivery to the delivery instruction unit 15 (step S305). In parallel with the process of step S305, the delivery determination unit 16 transmits a signal indicating that the vehicle 20 is to be delivered to the user terminal 30 (step S306).

  If the arrival time estimated by the process of step S302 is several tens minutes to several hours after the current time (step S303: several tens minutes to several hours), the delivery determination unit 16 does not carry out the delivery of the vehicle 20. It determines (step S307). Subsequently, the delivery determination unit 16 automatically resets the delivery time of the vehicle 20 based on the estimated arrival time (step S308). Next, the delivery determination unit 16 transmits a signal indicating the reset delivery time to the user terminal 30 (step S309).

  In addition, when the arrival time estimated when the delivery instruction is issued is several dozen minutes to several hours after the current time, the delivery determination unit 16 determines the arrival time estimated in the process of step S308, The delivery time according to the vehicle 20 is automatically set.

  If the arrival time estimated by the process of step S302 is several hours or more after the current time (step S303: several hours or more), the delivery determination unit 16 determines that the delivery of the vehicle 20 is not performed (step S310) . Subsequently, the delivery determination unit 16 transmits, to the user terminal 30, a signal indicating that the delivery of the vehicle 20 is not performed and a message prompting resetting of the delivery time (step S311). Next, the delivery determination unit 16 determines whether a new delivery time has been acquired (for example, whether or not a signal indicating a new delivery time has been received from the user terminal 30) (step S312). In this determination, when it is determined that a new leaving time has not been acquired (step S312: No), the determination in step S312 is performed again after the second predetermined period (for example, several tens of milliseconds to several hundreds of milliseconds) has elapsed. . On the other hand, when it is determined that a new leaving time has been acquired (step S312: Yes), the leaving determination unit 16 updates the leaving time of the vehicle 20, and ends the leaving process determination illustrated in FIG.

  If the arrival time estimated when the delivery instruction is issued is several hours or more after the current time, the delivery determination unit 16 outputs a signal indicating that the delivery instruction can not be received in the process of step S311. Send to 30

  Referring back to FIG. 4 again, after the above-described delivery process determination, the delivery instruction unit 15 determines whether or not immediate delivery is performed (step S214). In this determination, when it is determined not to be immediate leaving (step S214: No), the leaving instruction unit 15 again determines the determination in step S211 after the third predetermined period (for example, several tens of milliseconds to several hundreds of milliseconds) has elapsed. Do.

  On the other hand, when it is determined in step S214 that the immediate delivery is determined (step S214: Yes), the delivery instruction unit 15 transmits the delivery notification to the vehicle 20 via the communication unit 11 (step S215). The ECU 22 of the vehicle 20 that has received the delivery notification cancels the standby mode.

  Next, the delivery instruction unit 15 refers to, for example, traveling route information and the like stored in the parking lot DB 13 to determine the standby position of the vehicle 20 at the boarding place and the traveling route from the parking place to the standby position. Then, a signal indicating the determined standby position and traveling route is transmitted to the vehicle 20 (step S216).

  The ECU 22 of the vehicle 20 acquires a signal indicating the standby position and the traveling route (step S221). Next, while referring to the travel route indicated by the acquired signal, the ECU 22 takes into consideration the obstacle around the vehicle 20 detected by the vehicle surroundings monitoring function, for example, and the vehicle 20 receives the travel route generation function. Generate a travel route to be actually traveled. Then, the ECU 22 controls, for example, an engine, a motor, various actuators, and the like so that the vehicle 20 travels along the generated travel route by the automatic driving function. After the vehicle 20 moves to the vicinity of the standby position indicated by the acquired signal through the delivery gate, the ECU 22 detects the standby position by the parking position search function, and the vehicle 20 is at the standby position by the automatic parking function. Park at (Step S222).

(Technical effect)
In the parking lot management device 10, it is determined whether to actually leave the vehicle 20 based on the arrival time based on the distance between the current position of the user and the boarding place. Therefore, it is possible to suppress a situation where the vehicle 20 waits for a relatively long time at a boarding place where space is limited. In other words, the occupancy time of the riding place of the vehicle 20 can be suppressed. As a result, it is possible to avoid a situation in which the following vehicle can not move to the boarding place because the vehicle 20 occupies the boarding place for a relatively long time.

  In the parking lot management device 10, in particular, when the estimated arrival time is several dozen minutes to several hours after the current time, the delivery determination unit 16 automatically resets the delivery time. When the estimated arrival time is several hours or more from the current time, the delivery determination unit 16 transmits a message to the user terminal 30 to prompt resetting of the delivery time. Therefore, according to the parking lot management device 10, it is possible to avoid the situation in which the vehicle 20 is delivered according to the initially set delivery time.

  By performing the above-mentioned delivery processing, the vehicle of the user who can get on immediately will be mainly moved to the boarding place. As a result, the waiting time of the vehicle at the boarding place is reduced, and smooth delivery of the parked vehicle can be expected. Therefore, according to the parking lot management device 10, it is possible to carry out appropriate parking of the parked vehicle.

<Modification>
In the first embodiment described above, it is premised that the vehicle 20 is configured to be capable of automatically traveling. For example, the above-mentioned parking lot management device 10 can be applied to a parking lot provided with a transport mechanism capable of transporting a vehicle on a pallet (cargo) together with the pallet or transporting the vehicle by a conveyor. . In such a parking lot, vehicles that do not have an automatic travel function can also be targeted.

  Various aspects of the invention derived from the embodiment and the modification described above will be described below.

  A management apparatus according to an aspect of the present invention is a management apparatus for carrying out the leaving of a vehicle from a parking lot by causing the vehicle to self-propelled, and is a predetermined time before the leaving time designated by the user of the vehicle Alternatively, when the user issues an exit instruction from the user, the arrival time of the user to the planned vehicle arrival position is obtained based on the acquisition means for acquiring the current position of the user and the acquired current position. An estimation means for estimating and an adjustment means for adjusting the leaving time of the vehicle in consideration of the estimated arrival time are provided. In the embodiment described above, the “delivery determination unit 16” corresponds to an example of an acquisition unit, an estimation unit, and an adjustment unit.

  “Self-propelled” is a concept including not only automatic travel of a vehicle by an automatic driving function, for example, but also automatic transport (movement) of the vehicle by a transport mechanism such as a conveyor. “Adjustment of delivery time” is a concept including not only the automatic adjustment of the delivery time but also the proposal of resetting of the delivery time to the user.

  In the management apparatus, the arrival time of the user to the expected boarding position is estimated based on the current position of the user, and the leaving time of the vehicle is adjusted in consideration of the estimated arrival time. For this reason, when it takes a considerable amount of time before the user arrives at the expected boarding position, the leaving time is adjusted (for example, reset), so that the vehicle is prevented from continuing to stand by at the expected boarding position. be able to. When it is estimated that the user arrives at the planned boarding position relatively early, the vehicle is delivered in accordance with the designated delivery time or delivery instruction. Therefore, according to the management device, the parked vehicle can be properly delivered.

  The present invention is not limited to the embodiment described above, and can be suitably modified without departing from the scope or spirit of the invention as can be read from the claims and the specification as a whole, and a management apparatus with such a modification is also possible. Moreover, it is contained in the technical scope of this invention.
