Description

  The present invention relates to a mechanical parking lot.

  A mechanical parking lot is known as a parking lot capable of efficiently parking a large number of vehicles in a small space. A mechanical parking lot generally comprises a passenger compartment for a driver to get on or off the vehicle, a storage shelf provided on the ground or in the ground, and an elevator for moving the vehicle between the passenger compartment and the storage shelf And. Conventionally, a mechanical parking lot provided with a detection unit that detects the position and the presence of a vehicle in a passenger compartment has been proposed (see, for example, Patent Document 1). The document states that the inside of the passenger compartment is photographed by a camera, the photographing result is displayed on the display unit, and the user confirms the safety by looking at the display unit and operating the operation panel. . Furthermore, it is described that the detection result of the object by the detection unit is also displayed at the time of the safety confirmation.

Unexamined-Japanese-Patent No. 2016-3493 gazette

  However, in Patent Document 1, since the safety confirmation is performed by the operation of the user, some users may not carefully look at the imaging result displayed on the display unit and may perform the operation without performing the confirmation sufficiently.

  Moreover, although using the detection result by a detection part in safety confirmation is described in patent document 1, whether the detection object of each detection part has become an error in the same document (for example, the front part of a vehicle has protruded) Only the determination of whether or not is described.

  Here, the method described in Patent Document 1 has the following problems.

  First, an object such as a load may be placed in the passenger compartment. In this case, if the object is not collected prior to storage, the vehicle may collide with the object during storage. Although the presence of an object can be identified by the user's operation based on the photographing result, as described above, there is a risk that the user may fail to confirm. It is also possible to use the detection unit to specify that an object is present when the detection unit detects an object, and to notify the user of the presence. However, if this is done, the warehousing operation is finished, and when the vehicle is already in the passenger compartment, there is a possibility that the vehicle is erroneously detected as an object such as a load and notification is given.

  Also, a problem occurs when the detection unit is broken. If it is not specified that the detection unit is broken, it is impossible to repair the detection unit by the manager of the parking lot. However, the method described in Patent Document 1 does not describe the specifying method, and it may take time to specify the failure. Since entry and exit of the vehicle can not be performed while there is a failure, if it takes time to identify the failure, the time required for the user to enter and exit may be long.

  The present invention has been made in view of such a situation, and one of the exemplary objects of an embodiment thereof is to solve at least one of the above-mentioned problems, more specifically, in the case of using a detection unit. It is an object of the present invention to provide a mechanical parking lot which can detect the presence of an object in a passenger compartment more suitably and / or can detect a failure of the detection unit earlier.

  In order to solve the above problems, a mechanical parking lot according to an aspect of the present invention is a mechanical parking lot for moving a vehicle entering a passenger compartment to a storage rack, and a plurality of mechanical parking lots for detecting the presence of an object in the passenger compartment. And a controller for controlling the operation of the mechanical parking lot. The control device executes a predetermined notification process when the detection results of the plurality of detection units contradict each other.

  It is to be noted that any combination of the above-described constituent elements, or one obtained by replacing the constituent elements and expressions of the present invention among methods, apparatuses, systems, etc. is also effective as an aspect of the present invention.

  ADVANTAGE OF THE INVENTION According to this invention, when using a detection part, the mechanical parking lot which can detect the presence of the object in a passenger compartment more suitably, and / or can detect failure of a detection part earlier can be provided.

The outline of the mechanical parking lot according to the embodiment is as follows.
The mechanical parking lot according to the embodiment includes an existing vehicle detection device for detecting the presence of a vehicle in a passenger compartment, and a sensor for detecting the protrusion of the vehicle from the pallet. If the presence detection device does not detect the presence of a vehicle, that is, although the vehicle does not exist in the passenger compartment, the protrusion sensor indicates a detection result indicating that the vehicle has detected protrusion, the vehicle in the passenger compartment is different from the vehicle It is conceivable that an object is present or the overturn sensor is broken. In such a case, it is not possible to accurately guide the vehicle. Therefore, in the present embodiment, even if the existing vehicle detection device does not detect the presence of a vehicle, a case in which the overrun sensor indicates a detection result indicating that the vehicle overrun is detected, that is, detection by the existing vehicle detection device When the result and the detection result by the overtaking sensor contradict each other, a notification process is performed to notify that effect.

The "operation" mode is a mode in which the mechanical parking lot 10 is operated normally, the "stop" mode is a mode in which the operation of the mechanical parking lot 10 is stopped, and the "management" mode executes a predetermined management menu Mode for

  In FIG. 2, the touch panel 44 displays a loading / unloading operation screen displayed when loading / unloading a vehicle. The storage operation screen has a number display area 62 for displaying the input vehicle management number, a ten key 61, a storage button 63, a storage button 64, and a storage button 65.

  At the time of storage, the user or the clerk stops the vehicle to be stored outside the passenger room 12 and operates the operation panel 28. The user or the clerk presses the ten key 61 to display the vehicle management number of the own vehicle in the number display area 62, and presses the storage button 63. When the storage button 63 is pressed, the operation panel 28 generates a storage request signal including the input vehicle management number, and transmits the generated storage request signal to the control device 30. The control device 30 executes a process for calling an empty pallet 32 on which the vehicle is not loaded into the passenger compartment 12. Details of processing by the control device 30 will be described later.

  When an empty pallet 32 is prepared in the passenger compartment 12, the user or a person in charge enters a passenger vehicle into the passenger compartment 12 and loads it on the pallet 32. After confirming that there is no person inside the passenger compartment 12, the store button 64 is pressed. When the storage button 64 is pressed, the operation panel 28 generates a storage request signal and transmits the storage request signal to the control device 30.

  At the time of delivery, the user or the clerk presses the ten key 61 to display the vehicle management number of the own vehicle in the number display area 62, and presses the delivery button 65. When the delivery button 65 is pressed, the operation panel 28 generates a delivery request signal including the input vehicle management number, and transmits the delivery request signal to the control device 30. The control device 30 executes processing for calling the pallet 32 on which the vehicle specified by the vehicle management number included in the delivery request signal is placed to the passenger compartment 12.

  FIG. 3 is a plan view of the passenger compartment 12. The passenger compartment 12 is substantially rectangular in plan view in the present embodiment. Hereinafter, the x direction is taken as the left-right direction of the passenger compartment 12 and the y direction as the front-rear direction of the passenger compartment 12. The front-rear direction is the direction in which the vehicle enters the passenger compartment 12 from the outside. In particular, looking at the inside of the passenger compartment 12 in the front-rear direction from the storage / unloading opening 12a, the back side is front, the front side (that is, the side where the loading / closing opening 12a is provided) is back, the left is left, and the right is right .

  The mechanical parking lot 10 further includes an existing vehicle detection device 35, a left protrusion sensor 36, a right protrusion sensor 37, a front protrusion sensor 38, and a rear protrusion sensor 39.

  The in-vehicle detection device 35 is a detection device for detecting the presence of a vehicle in the passenger compartment 12, specifically, for example, detecting the presence of a vehicle stopped at a stop position on the pallet 32. The vehicle detection device 35 is an optical detection device in the present embodiment, and is attached to the right wall. The vehicle detection device 35 includes a light emitting unit (not shown) that emits a laser beam of a predetermined wavelength, and a light receiving unit (not shown) that is configured to detect light of a wavelength equivalent to that wavelength. The light emitting unit emits laser light above the pallet 32.

  When the vehicle is stopped at the stopping position on the pallet 32, a part of the laser light emitted from the light emitting unit of the vehicle detection device 35 is reflected by the vehicle. Part of the reflected laser light returns to the vehicle detection device 35. The light receiving unit of the vehicle detection device 35 detects the reflected light that has returned. When the present vehicle detection device 35 detects the reflected light corresponding to the predetermined time after the present vehicle detection device 35 emits the laser light, the vehicle is stopped at the stop position of the pallet 32, that is, the passenger room 12 It is determined that there is a vehicle inside. The predetermined time is determined based on the emission angle of the laser light. The vehicle detection device 35 transmits the detection result to the control device 30.

  The left protrusion sensor 36 is attached to the front wall of the passenger compartment 12. The left protrusion sensor 36 is an optical detection device for detecting the protrusion of the vehicle from the left detection surface 50, and a light emitting unit (not shown) that emits laser light of a predetermined wavelength and a wavelength equal to that wavelength A light receiving unit (not shown) configured to detect light. The light emitting unit emits laser light in the left detection plane 50 substantially parallel to the yz plane. The light projector scans the entire left detection surface 50 with the laser light by rotating the path of the laser light about the x axis. In the present embodiment, the left detection surface 50 is provided along the left long side of the pallet 32 in a plan view. The orthogonal direction orthogonal to the left detection surface 50 is the left and right direction.

  A case where a part of the vehicle protrudes from the left detection plane 50 is considered. The light emitting unit of the left protrusion sensor 36 scans the left detection surface 50 with a laser beam. A portion of such laser light is reflected by the overrun point of the vehicle. A part of the reflected laser light returns to the left protrusion sensor 36. The light receiving portion of the left protrusion sensor 36 detects the reflected light thus returned. When the left protrusion sensor 36 detects the corresponding reflected light within a predetermined time after the left protrusion sensor 36 emits the laser light, the left protrusion sensor 36 determines that there is a protrusion from the left detection surface 50. The predetermined time is determined based on the emission angle of the laser light and the size of the left detection surface 50. The left protrusion sensor 36 transmits the detection result to the control device 30.

  The right protrusion sensor 37 is attached to the front wall of the passenger compartment 12. The right protrusion sensor 37 is an optical detection device for detecting the protrusion of the vehicle from the right detection surface 51, and is configured in the same manner as the left protrusion sensor 36. In the present embodiment, the right detection surface 51 is provided along the long side on the right side of the pallet 32 in a plan view.

  The front protrusion sensor 38 is an optical detection device for detecting the protrusion of the vehicle from the front detection surface 52, and includes a light projector 38a that emits light and a light receiver 38b that is configured to detect the light. . The light emitter 38a and the light receiver 38b are attached to the left wall and the right wall, respectively. The light projector 38 a and the light receiver 38 b may be erected on the floor of the passenger compartment 12. The light projector 38a emits light in a direction substantially parallel to the x direction. The front detection surface 52 is a substantially rectangular surface whose lower side is the optical axis of the light emitted by the light projector 136a. Conversely, the light projector 38 a is mounted in the passenger compartment 12 so that the optical axis of the light to be emitted coincides with the lower side of the front detection surface 52. In the present embodiment, the front detection surface 52 is provided along the front short side of the pallet 32 in plan view. The direction orthogonal to the front detection surface 52 is the front-rear direction.

  A case where a part of the vehicle protrudes from the front detection surface 52 is considered. The light projector 38a of the forward sensor 38 emits sheet-like light toward the light receiver 38b. A part of such light is blocked by the protruding part of the vehicle, and the light receiver 38b does not detect a part of the light emitted by the light projector 38a. The front protrusion sensor 38 determines that there is a protrusion from the front detection surface 52 when the light receiver 38 b does not detect a part of the light. The front protrusion sensor 38 transmits the detection result to the control device 30.

  The back protrusion sensor 39 is an optical detection device for detecting the protrusion of the rear detection surface 53, and includes a light projector 39a and a light receiver 39b. The light emitter 39a and the light receiver 39b are attached to the left side wall and the right side wall, respectively. The light projector 39 a and the light receiver 39 b may be erected on the floor of the passenger compartment 12. The light projector 39a and the light receiver 39b are configured in the same manner as the light projector 38a and the light receiver 38b, respectively. In the present embodiment, the rear detection surface 53 is provided along the rear short side of the pallet 32 in a plan view.

  FIG. 4 is a block diagram showing the function and configuration of the control device 30. As shown in FIG. Each block shown here can be realized by hardware as an element or mechanical device including a CPU (central processing unit) of a computer, and as software as a computer program or the like. It depicts the functional blocks realized by the coordination of them. Therefore, it is understood by those skilled in the art who have been mentioned in the present specification that these functional blocks can be realized in various forms by a combination of hardware and software.

  Control device 30 includes a storage processing unit 118, a delivery processing unit 120, a determination unit 122, a notification unit 124, and a parking status holding unit 126.

  The parking status holding unit 126 holds the parking status of the mechanical parking lot 10. In particular, the parking status holding unit 126 identifies the space ID for identifying the parking space, information indicating whether the vehicle is parked in the parking space, and identifies the vehicle when the vehicle is parked in the parking space. And the corresponding vehicle management number.

  The storage processing unit 118 includes a guidance processing unit 130, a space selection unit 132, and a storage processing unit 134.

  At the time of vehicle warehousing, the user or the attendant stops the vehicle to be warehousing out of the passenger room 12 and dismounts, and inputs the warehousing request to the operation panel 28. When receiving the storage request signal, the guidance processing unit 130 controls the lifting device 94, the first transfer device 56, and the second transfer device 58 such that an appropriate empty pallet 32 is disposed in the passenger compartment 12.

  The guidance processing unit 130 guides a vehicle, which is an object of warehousing, to a stop position on the pallet 32 disposed in the passenger compartment 12 by voice or a vehicle guidance light (not shown). The guidance processing unit 130 causes the vehicle guidance light to display an instruction for canceling the overrun when the overrun sensor detects an overrun during guidance. For example, when the detection result from the right protrusion sensor 37 indicates that a protrusion from the right detection surface 51 occurs, the guidance processing unit 130 causes the vehicle guidance light to display a left-pointing arrow.

  After the vehicle enters the passenger compartment 12 and stops on the pallet 32, the user or the attendant gets off and inputs a storage request to the operation panel 28. When receiving the storage request signal, the space selection unit 132 refers to the parking status holding unit 126 and selects the space ID of the parking space in which the vehicle is not parked.

  The storage processing unit 134 lifts and lowers the pallet 32 on which the vehicle is mounted from the passenger compartment 12 to the parking space specified by the space ID selected by the space selection unit 132, and the first transfer device 56. , The second transfer device 58 is controlled.

  At the time of vehicle leaving, a user or a clerk inputs a leaving request to the operation panel 28. When the delivery processing unit 120 receives the delivery request signal, the elevator device 94 is configured to move the pallet 32 mounted with the vehicle specified by the vehicle management number included in the delivery request signal from the storage shelf to the landing 12. The transfer device 56 and the second transfer device 58 are controlled. When the vehicle appearing in the passenger compartment 12 moves out of the passenger compartment 12, the delivery is determined.

  The determination unit 122 determines whether the detection results by the plurality of detection devices are inconsistent, specifically, whether the detection result by the existing vehicle detection device 35 and the detection result by the overtaking sensor are inconsistent. Execute conflict determination processing. If the detection results are contradictory, it means that the protrusion sensor detects the protrusion of the vehicle even though the existing vehicle detection device 35 does not detect the presence of the vehicle. In this contradiction state, the protrusion sensor is in the detection failure state, specifically, there is an object different from the vehicle in the passenger compartment 12 and the protrusion sensor detects the object, or the protrusion sensor Caused by the failure of As a failure of the protrusion sensor, there is an internal failure, a shift of the optical axis between the light projector and the light receiver, and the like.

  The determination unit 122 executes the contradiction determination process in a predetermined cycle (for example, a 0.1 second cycle) for each of the protruding sensors. For example, the determination unit 122 may always execute the contradiction determination process during the normal operation of the mechanical parking lot 10 or, for example, executes the contradiction determination process only when the pallet 32 is prepared in the passenger compartment 12. Alternatively, for example, the contradiction determination process may be executed only when the overrun sensor detects an overrun of the vehicle.

  The notification unit 124 executes a notification process of notifying that the out-of-focus sensor has a detection result that is inconsistent with the vehicle detection device 35, in other words, a notification process of notifying that the out-of-line sensor is in a detection failure state. Do. In the notification process, there are a first notification process informing that there may be an object different from the vehicle in the passenger compartment 12, and a second notification process informing that a failure may exist in any of a plurality of overhang sensors. There are two types.

  The first notification process is executed when the contradiction state continues for 30 seconds (second time) or more. In the first notification process, the display on the touch panel 44 of the operation panel 28 is switched from the entry / exit operation screen to a detection status display screen indicating the detection status of each sensor. That is, by displaying the detection status display screen, the user or the like is notified that an object different from the vehicle may exist in the passenger compartment 12 and the approximate position where the object may exist.

  FIG. 5 shows a detection status display screen. In the detection status display screen, an existing vehicle detection device icon 135, a left protrusion sensor icon 136, a right protrusion sensor icon 137, a front protrusion sensor icon 138, and a rear sensor icon 139 are actually present vehicle detection devices 35 and a left protrusion sensor. 36, the right protrusion sensor 37, the front protrusion sensor 38, and the rear protrusion sensor 39 are arranged in a form that simulates.

  On the detection status display screen, the icon of the protrusion sensor in the detection failure state is highlighted. For example, the overrun sensor icon in the detection failure state is displayed in a color with a relatively large contrast with the background color, and the outlier sensor icon is displayed in a color with a relatively small contrast with the background color. FIG. 5 shows an example in which the front protrusion sensor icon 138 is highlighted. This implies that an object such as a luggage may be present at a position corresponding to the forward sensor 38. In this case, it can be understood that the user may check whether or not the baggage is not left at the position corresponding to the forward sensor.

  Returning to FIG. 4, when the first notification process is executed, the operation panel 28 does not receive the storage and storage process. When the contradiction is eliminated by the user etc. recovering the package before the second notification process is executed, the notification unit 124 enters the display of the touch panel 44 of the operation panel 28 from the detection status display screen. Switch to the delivery operation screen (return).

  The second notification process is performed when the contradiction continues for three minutes (first time which is longer than the second time). In the second notification process, the overrun sensor in the detection failure state is treated as a failure, and the occurrence of the failure is reported to the user, a person in charge, or the like. For example, the notification unit 124 causes a failure screen (not shown) to be displayed on the touch panel 44 of the operation panel 28, and a failure occurs in a display unit (for example, a monitor installed at a waiting place such as a worker) referred to by a clerk Display a message. A clerk rushes to the mechanical parking lot 10 in response to the notification.

  The rushed attendant performs a predetermined manager input on the operation panel 28. This manager input is, for example, to put the key possessed by the clerk or the like into the keyhole of the mode switching unit 46 of the operation panel 28 of FIG. When the administrator input is executed, the notification unit 124 causes the touch panel 44 of the operation panel 28 to display an administrator detection status display screen.

  FIG. 6 shows an administrator detection status display screen. Similar to the detection status display screen of FIG. 5, the detection status display screen for the administrator includes the existing vehicle detection device icon 135, the left protrusion sensor icon 136, the right protrusion sensor icon 137, the front protrusion sensor icon 138, and the rear sensor icon 139 are arranged in a form that imitates the arrangement of the actual vehicle detection device 35, the left protrusion sensor 36, the right protrusion sensor 37, the front protrusion sensor 38, and the rear protrusion sensor 39. An attendant or the like can identify the overrun sensor in which the failure has occurred by referring to the overrun sensor icon. In FIG. 6, the front protrusion sensor icon 138 is highlighted. This indicates that the pre-exposure sensor 38 has a failure.

  Further, an error code display field 140 is included in the detection status display screen for administrator. The error code display field 140 displays an error code for uniquely identifying a failure. In addition to the display of the over-exposure sensor icon, the clerk or the like can identify the over-exposure sensor in a failure state also by the error code.

  The clerk or the like resolves the failure state by repairing or replacing the out-of-space sensor, or by removing the left-over baggage or the like. After the second notification processing, the notification unit 124 does not return to the storage operation screen only when the failure is eliminated, and when a clerk or the like executes a predetermined recovery operation, in this embodiment, the detection status display screen for the administrator When the restart operation button 142 is pressed, the screen returns to the storage operation screen.

  The operation of the mechanical parking lot 10 configured as described above will be described.

  The determination unit 122 executes the contradiction determination process in a predetermined cycle (for example, a 0.1 second cycle) for each of the protruding sensors. When the contradiction state continues for 30 seconds or more, the notification unit 124 switches the display on the touch panel 44 of the operation panel 28 from the loading / unloading operation screen to the detection status display screen as the first notification process. The user can notice that the package is left by referring to the detection status display screen. If the contradiction state is resolved in less than 3 minutes, the notification unit 124 returns the display of the touch panel 44 of the operation panel 28 from the detection status display screen to the storage and storage operation screen.

  When the contradiction state continues for three minutes or more, the notification unit 124 notifies an agent or the like that a failure has occurred as the second notification process. The clerk or the like executes administrator input to display the administrator detection status display screen on the touch panel 44 of the operation panel 28. The clerk or the like refers to the detection status display screen for management to identify the overrun sensor in the failure state, and repair or replace the overhaul sensor or remove the leftover baggage to eliminate the fault and restore it. Perform the operation

  According to the mechanical parking lot 10 according to the embodiment described above, when the detection result by the existing vehicle detection device 35 and the detection result by the overtaking sensor contradict each other, the notification process is performed. As a result, it is possible to detect that the protrusion sensor is in a detection failure state, as well as when the vehicle is put in and out.

  Further, according to the mechanical parking lot 10 according to the embodiment, when a contradiction state continues for 30 seconds (second time) or more with respect to a certain protrusion sensor, that is, an object different from the vehicle exists in the passenger compartment 12 When it is estimated that it does, 1st alerting | reporting process is performed. Thus, the user can notice that an object such as a load is present in the passenger compartment. Further, in the first notification process, the display on the touch panel 44 of the operation panel 28 is switched from the entry / exit operation screen to the detection status display screen. If the cause of the detection sensor being out of range is that the user leaves the package, the user is likely to be near the mechanical parking lot 10 when the first notification process is executed, and the detection status display screen is displayed. It is likely to see. Therefore, according to the mechanical parking lot 10, it is expected that the user notices that the package is left and copes with it, and the detection failure state is quickly resolved.

  Further, according to the mechanical parking lot 10 according to the embodiment, when the contradiction state continues for three minutes (first time) or more with respect to the certain over-travel sensor, that is, the certain over-travel sensor is broken. When it is estimated, the second notification process is performed. This makes it possible to identify the failure of the overrun sensor early.

  Moreover, according to the mechanical parking lot 10 which concerns on embodiment, the alerting | reporting process to perform is switched from a 1st alerting | reporting process to a 2nd alerting | reporting process 30 seconds (second time) after contradiction state arises. As a result, the first notification process is performed for a long time despite the fact that the overturn sensor has actually failed, that is, the user is erroneously notified that there is an object in the passenger compartment. It can be suppressed. Furthermore, in reality, only an object is present in the passenger compartment, and even if the user is recovering the object just by recovering the object, the second notification process is performed from the beginning to carry out the second person in charge. It is also possible to suppress the unnecessary repair operation of the detection unit.

  The configuration and operation of the mechanical parking lot according to the embodiment have been described above. This embodiment is an exemplification, and it is understood by those skilled in the art that various modifications can be made to the combination of the respective constituent elements, and such modifications are also within the scope of the present invention. Hereinafter, modified examples will be described.

(Modification 1)
In the embodiment, although the case where the plurality of detection units are the in-vehicle detection device and the protrusion sensor has been described, the present invention is not limited thereto. At least one of the plurality of detection units is a sensor capable of normally detecting the presence of the vehicle in the passenger compartment 12 and the other one is a vehicle in the passenger compartment 12 Even when it is time, it is sufficient if it can not normally detect its presence. As the former sensor, it may be possible to detect whether or not an object is present in an area different from the end of the area to which the vehicle in the passenger compartment 12 is to enter and preferably in the vicinity of the center. On the other hand, as the latter sensor, any sensor may be used as long as an object is present in the vicinity of the end of the area where the vehicle in the passenger compartment 12 is scheduled to enter. For example, as the latter sensor, a sensor for detecting the position of the front wheel of a vehicle can also be used.

(Modification 2)
In the embodiment, the notification unit 124 displays the detection status display screen for displaying the detection status of each detection unit as the first notification processing on the touch panel 44 of the operation panel 28, but the present invention is not limited thereto. . The notification unit 124 may display a screen indicating an approximate position at which a luggage or the like may be left as a first notification process, instead of the detection status display screen indicating the detection status of each detection unit. . Although the first notification processing is mainly intended to notify the user, it is because the user can only cope with the removal of the left baggage.

(Modification 3)
Further, in the embodiment, a first notification process for notifying that an object different from a vehicle such as a load may exist in the passenger compartment, and a second notification process for notifying that a failure may exist in the detection unit. Although the case where both are performed was described, it is not restricted to this. For example, only the first notification process may be executed without performing the second notification process. Even in such a case, by performing the first notification process, it is possible to make the user notice that there is a possibility that an object is present in the passenger compartment. Further, only the second notification process may be executed without performing the first notification process. By performing the second notification process, it is possible to early identify the failure of the detection unit.

(Modification 4)
Further, in the embodiment, the first time, which is the timing to start the second notification process, is set to 3 minutes, and the second time, which is the timing to start the first notification process, is set to 30 seconds. It may be a different time. However, it is preferable that the second time is shorter than the first time.

(Modification 5)
Further, in the embodiment, the screen display on the touch panel 44 of the operation panel 28 has described the case where it is notified that the protrusion sensor is in the detection failure state or which protrusion sensor is in the detection failure state. It is not limited.

  The notification unit 124 is used to notify that a sensor for detection of the protrusion sensor is in a detection failure state from a speaker (not shown) of the operation panel 28 in addition to or in place of the screen display on the touch panel 44 of the operation panel 28. A buzzer sound or an announcement voice may be output. As a result, the user or a person in charge can recognize that the detection sensor has a detection failure.

  In addition, the notification unit 124 may aurally notify the user, a person in charge, or the like in the passenger compartment 12 in order to prompt recovery. Specifically, for example, the notification unit 124 may output an announcement voice for prompting recovery of the detection failure state of the overturn sensor from the unshown speaker in the inside of the room 12 to the inside of the room 12. The announcement sound prompting for recovery may indicate, for example, the position of the protruding sensor in the detection failure state, and there is a possibility that an object such as a package causing the contradiction state may be placed in the passenger compartment 12 It may indicate an approximate position that may or may be placed.

  In addition, the notification unit 124 may visually notify the user or the like in the passenger compartment 12 in order to prompt recovery. Specifically, for example, when a light source (for example, an LED) is provided adjacent to the protrusion sensor, the notification unit 124 is in the detection defect state to notify the user etc. of the protrusion sensor in the detection defect state. The light source adjacent to the protrusion sensor may be turned on. Also, for example, when the image display device is provided in the passenger compartment 12, the notification unit 124 may display an image indicating the position of the over sensor in the detection failure state on a wall or the like in the passenger compartment 12, For example, the unit 124 may display a predetermined image at an approximate position where an object such as a package causing a contradiction state may be placed in the passenger compartment 12.

  In addition, when the detection failure state of the protrusion sensor is eliminated, the notification unit 124 may aurally and / or visually notify that effect to the inside of the passenger compartment 12 when the detection failure state of the protrusion sensor is resolved. As a result, although it went out of the passenger compartment 12 because it thought that the detection defect state has been eliminated, the detection defect state is not actually eliminated and is not woven, and it takes time and effort twice to enter the passenger compartment 12 again. It can be suppressed to occur.

  Combinations of any of the embodiments and variations described above are also useful as embodiments of the present invention. The new embodiments resulting from the combination combine the effects of each of the combined embodiments and variations.
