Description

Technical Field

[0001] The present invention relates to a home door control device that performs opening and closing operations in cooperation with a vehicle door and a home door.

Background Art

[0002] For example, there is known a device that detects the state around a platform door and determines a dash boarding in a short time (see Patent Document 1).

[0003] On the other hand, from the viewpoint of safety, for example, to prevent passengers from being left between the vehicle and the platform, after performing cooperation between doors based on communication between the vehicle side and the ground side, there are some devices that perform door opening and closing. In a home door control device that performs opening and closing operations in cooperation with a vehicle door and a home door, for example, even when there is pinching in the vehicle door due to dash boarding, there is a possibility that a prompt response (opening of the vehicle door) cannot be performed. In the control mode of the home door shown in Patent Document 1, there is no mention of a configuration for dealing with such a situation.

Summary of the Invention

[0005] The present invention has been made in view of the above points, and an object thereof is to provide a home door control device that can quickly open the vehicle door when pinching occurs in the vehicle door, for example, due to dash boarding.

[0006] The home door control device for achieving the above object is a home door control device that performs opening and closing operations in cooperation with a vehicle door and a home door. When there is a vehicle door opening signal when the vehicle door opening command is activated, the vehicle door opening is started by prioritizing the vehicle door opening command over the cooperation between the doors.

[0007] In the above home door control device, when there is a vehicle door opening signal when the vehicle door opening command is activated, by starting the vehicle door opening by prioritizing the vehicle door opening command over the cooperation between the doors, even when performing opening and closing operations in cooperation with the vehicle door and the home door, in an emergency situation such as when pinching occurs in the vehicle door, a prompt response, that is, the vehicle door can be opened.

[0008] In a specific aspect of the present invention, the cooperation between the doors is performed based on communication between the on-vehicle side and the ground side. When there is a vehicle door opening signal when the vehicle door opening command is activated, the vehicle door opening is started regardless of the response from the ground side to the home door opening command output from the on-vehicle side to the ground side. In this case, even when the cooperation between the doors is performed based on communication between the on-vehicle side and the ground side, in an emergency situation such as when pinching occurs, the vehicle door can be quickly opened.

[0009] In another aspect of the present invention, when there is no vehicle door opening signal when the vehicle door opening command is activated, the vehicle door opening is started after waiting for the response from the ground side to the home door opening command. In this case, while enabling a prompt vehicle door opening in an emergency, an appropriate cooperation between the doors can be maintained.

[0010] In still another aspect of the present invention, the home door opening command is output in accordance with the activation of the vehicle door opening command. In this case, the cooperation between the doors using communication can be appropriately maintained.

[0011] In yet another aspect of the present invention, when it is output from the vehicle side to the ground side that there is a vehicle door opening signal together with a home door opening command, on the ground side, the home door to be opened is selected. In this case, the opening operation can be restricted within the necessary range.

[0012] In yet another aspect of the present invention, when it is output from the vehicle side to the ground side that there is a vehicle door opening signal together with a home door opening command, on the ground side, the timing of home door opening is delayed. In this case, an appropriate difference can be provided between the timing of vehicle door opening and the timing of home door opening.

[0013] In yet another aspect of the present invention, the cooperation between the doors is performed based on communication between the vehicle side and the ground side. When there is a vehicle door opening signal when a vehicle door opening command is activated, a home door opening command is not output from the vehicle side to the ground side, and the home door is maintained in a closed state. In this case, in the event of pinching or the like, the occurrence of further rushing into the vehicle from the home door can be avoided.

[0014] In yet another aspect of the present invention, the vehicle door opening command is output by operating the conductor door switch. In this case, an appropriate and rapid opening operation is performed according to the operation by the conductor.

Mode for Carrying Out the Invention

[0016] 〔First Embodiment〕 Hereinafter, with reference to FIG. 1 and the like, the home door control device according to the first embodiment of the present invention will be described. FIG. 1 is a block diagram conceptually showing an example of the schematic configuration of the home door control device 100 of the present embodiment. Further, FIG. 2 is a diagram corresponding to FIG. 1 and is a block diagram showing the home door control device 100X of the comparative example.

[0017] As shown in FIG. 1, the home door control device 100 of the present embodiment is composed of a ground device 10 and an on-vehicle device 50. In the home door control device 100, wireless communication is performed between the ground device 10 and the on-vehicle device 50, so that the opening and closing operations are carried out in cooperation with respect to the vehicle door (vehicle side door) RD and the home door (home side door) PD.

[0018] First, among the home door control device 100, the ground device 10 is housed in a housing CS that constitutes the home door equipment, and is composed of a home door control device 11, a ground-side wireless communication device 12, and a radio 13.

[0019] The home door control device 11 transmits a drive signal such as a home door opening signal to a drive unit (not shown) of the home door PD in order to perform the opening and closing operation of the home door (home-side door) PD. In particular, here, the home door control device 11 transmits a drive signal to the home door PD in accordance with various commands from the ground-side wireless communication device 12, and as an ACK (positive response / confirmation response) for cooperation with the on-vehicle side, that is, an answer back, for example, a door opening ACK for the door opening command from the ground-side wireless communication device 12 (hereinafter abbreviated as the opening ACK), is returned to the ground-side wireless communication device 12.

[0020] The ground-side wireless communication device 12 performs wireless communication with the on-vehicle side via the radio 13 to perform door-to-door cooperation, and transmits various command signals for the opening and closing operation corresponding to door cooperation to the home door control device 11. For example, when the ground-side wireless communication device 12 receives a home door opening command, which is a command for opening the home door PD from the on-vehicle side (corresponding to the opening of the vehicle door RD), via the radio 13, the ground-side wireless communication device 12 outputs the command to the home door control device 11. Also, as described above, various replies such as an opening ACK are made from the home door control device 11, and the ground-side wireless communication device 12 receives the reply and transmits the received reply (reply signal) to the on-vehicle side via the radio 13.

[0021] The radio 13 is an interface unit for performing wireless communication with the on-vehicle side and transmitting and receiving information as described above.

[0022] Next, among the home door control device 100, the on-vehicle device 50 is mounted in a vehicle CR of a train, and is composed of a vehicle door control device 51, an on-vehicle side wireless communication device 52, a radio 53, and a conductor door switch 54.

[0023] The vehicle door control device 51 transmits a drive signal such as a vehicle door opening signal to a drive unit (not shown) of the vehicle door (vehicle side door) RD in order to perform the opening and closing operation of the vehicle door RD. In particular, here, the vehicle door control device 51 transmits a drive signal to the vehicle door RD in accordance with various commands from the on-vehicle wireless communication device 52, and receives a vehicle door opening signal indicating whether the vehicle door RD is in the state of being opened from the vehicle door RD, and when receiving the vehicle door opening signal, outputs this to the on-vehicle wireless communication device 52 side. On the vehicle door RD side, there is a command line that is not pressurized unless it is in the closed state. In the above aspect, when the command line is not pressurized (= before closing the door), the vehicle door opening signal is output toward the on-vehicle wireless communication device 52.

[0024] The on-vehicle wireless communication device 52 performs door-to-door communication through wireless communication with the ground side via the wireless device 53, and transmits various command signals for the opening and closing operation corresponding to door-to-door communication to the vehicle door control device 51. Further, in the present embodiment, the on-vehicle wireless communication device 52 can independently perform the operation of the vehicle door RD according to the situation separately from the above door-to-door communication. Specifically, for example, when a vehicle door opening command is activated by using a conductor's door switch 54 described later, if there is a vehicle door opening signal from the vehicle door control device 51 (the state of having a vehicle door opening signal), the vehicle door opening of the vehicle door RD is started with priority over the door-to-door communication performed based on the communication between the on-vehicle side and the ground side. In the on-vehicle wireless communication device 52, in order to enable the above aspect, it has a communication signal processing unit 52a that performs signal processing for communication based on wireless communication with the ground side, and an in-vehicle signal processing unit 52b that performs signal processing inside the vehicle.

[0025] First, among the on-vehicle wireless communication devices 52, as shown in the figure, for example, when the cooperation signal processing unit 52a receives a vehicle door opening command branched from the conductor door switch 54, it transmits a home door opening command to the ground side via the radio 53 in order to open the home door PD on the ground side in response to this. Further, the cooperation signal processing unit 52a has a cooperation AND circuit CC, and when the vehicle door opening command branched from the conductor door switch 54 and the opening ACK from the ground side received via the radio 53 are input to the cooperation AND circuit CC, it transmits an output signal in response to this in order to cause the vehicle door control device 51 to perform opening control of the vehicle door RD. In this case, as a series of processes, first, when the vehicle door opening command by the conductor door switch 54 is activated, in response to this, the cooperation signal processing unit 52a transmits a home door opening command to the ground side via the radio 53. When the ground device 10 receives this, the above-described series of processes are performed to start the home door opening, and at this time, the opening ACK is transmitted to the on-vehicle side as a reply. When the on-vehicle device 50 receives the opening ACK, in the cooperation signal processing unit 52a, based on the vehicle door opening command that has already been input and the opening ACK, a vehicle door opening control output is made from the cooperation AND circuit CC. In the above case, the opening of the vehicle door RD will start after waiting for the response (opening ACK) from the ground side to the home door opening command issued from the on-vehicle side.

[0026] On one hand, among the on-vehicle upper-side wireless communication device 52, the in-vehicle signal processing unit 52b has an in-vehicle AND circuit OC as shown in the figure. When the vehicle door opening signal from the vehicle door control device 51 and the vehicle door opening command branched from the conductor door switch 54 are input to the in-vehicle AND circuit OC, accordingly, an output signal is transmitted to cause the vehicle door control device 51 to perform the opening control of the vehicle door RD. In this case, as a series of processes, the in-vehicle signal processing unit 52b waits for the input of the vehicle door opening command by the conductor door switch 54 and, in parallel with this, waits for the input of the vehicle door opening signal from the vehicle door control device 51. These signals are all transmitted inside the vehicle. If both are emitted inside the vehicle, the opening of the vehicle door RD will be started without requiring, for example, a response (opening ACK) from the ground side. That is, rather than the cooperation between the doors on the ground side and the on-vehicle side, the opening of the vehicle door RD is started with priority given to the vehicle door opening command. More specifically, when there is a vehicle door opening signal when the vehicle door opening command is activated, in the on-vehicle device 50, the opening of the vehicle door is started regardless of the response from the ground side to the home door opening command output from the on-vehicle side to the ground side. By adopting such a mode, even when the vehicle door RD and the home door PD perform the opening and closing operations through the cooperation between the doors, in the case of an emergency such as when pinching occurs in the vehicle door RD, a quick response, that is, the opening of the vehicle door can be performed by the sole judgment on the on-vehicle side.

[0027] As described above, the wireless device 53 is an interface unit for performing wireless communication with the ground side to transmit and receive information.

[0028] As described above, the conductor door switch 54 is a switch operated by the conductor and outputs an opening and closing operation command regarding the vehicle door RD. That is, the conductor door switch 54 is the source of the vehicle door opening command for starting the opening of the vehicle door RD.

[0029] The following describes the configuration overview of the home door control device 100X of the comparative example shown in FIG. 2, and by comparing it with the home door control device 100 of FIG. 1, the features of the home door control device 100 will be described.

[0030] As shown in the figure, the home door control device 100X of the comparative example is composed of a ground device 10X and an on-vehicle device 50X. Further, the ground device 10X is composed of a home door control device 11, a ground-side wireless communication device 12, and a radio 13, and the on-vehicle device 50X is composed of a vehicle door control device 51, an on-vehicle side wireless communication device 52, a radio 53, and a conductor door switch 54. That is, each configuration corresponds to each configuration of the home door control device 100 in FIG. 1. However, among the on-vehicle devices 50X, the home door control device 100X is different from the home door control device 100 in that a vehicle door opening signal is not output from the vehicle door control device 51 to the on-vehicle side wireless communication device 52, and in terms of the configuration of the on-vehicle side wireless communication device 52. Regarding the configuration of the on-vehicle side wireless communication device 52, the communication signal processing unit 52a has the same configuration as that of the home door control device 100 in FIG. 1, but the in-vehicle signal processing unit 52b shown in FIG. 1 is not provided in the home door control device 100X.

[0031] In the home door control device 100X configured as described above, regarding the cooperation between the ground side and the on-vehicle side, the cooperation signal processing unit 52a functions to perform the same operation as in the case of the home door control device 100 in FIG. 1. On the other hand, since there is no output of a vehicle door opening signal from the vehicle door control device 51 to the on-vehicle side wireless communication device 52 and the accompanying signal processing in the vehicle, an operation such as the opening of the vehicle door RD being preferentially handled regardless of the response from the ground side does not occur. In this regard, it is different from the case of the home door control device 100 in FIG. 1, where the vehicle door can be quickly opened in an emergency such as when pinching occurs.

[0032] The following describes a series of operations when the vehicle door is opened or closed with reference to the flowcharts in FIG. 3 and the like.

[0033] First, referring to the flowchart shown as FIG. 3, the normal operation of the vehicle door opening in the home door control device 100 will be described. Note that the normal operation of the vehicle door opening in the home door control device 100 is the same as that of the home door control device 100X in the comparative example illustrated in FIG. 2.

[0034] For example, when the arrival of the train at the station is confirmed, in the home door control device 100, through communication between the ground side and the on-vehicle side, the vehicle door RD and the home door PD are opened and closed with door-to-door cooperation. Therefore, first, from the vehicle side to the ground side, a home door opening command is output along with the activation of the vehicle door opening command. That is, an opening command (home door opening command) is transmitted from the on-vehicle device 50 to the ground device 10 (step S101). In response to this, when the ground device 10 transmits an opening ACK for the door to the on-vehicle device 50 as a reply (step S102), the on-vehicle device 50 receives this (step S103), and the opening operation of the vehicle door RD is started. Note that along with the transmission from the vehicle side to the ground side in step S101, on the ground side, that is, in the ground device 10, the opening operation of the home door PD is started (step S105). In the above case, on the ground side, it receives the command in step S101 and the opening operation of the home door PD is started, while on the vehicle side, it waits for the opening ACK from the ground side and then starts the opening operation of the vehicle door RD.

[0035] Here, regarding the closing of the vehicle door RD, if it is normal without pinching or the like occurring due to a rush boarding, it may be considered that, similar to the case of opening described above with reference to FIG. 3, communication is performed between the vehicle side and the ground side and the operation waits for a response from the ground side. However, when pinching or the like occurs in the vehicle door RD, it is desired to switch from the closing operation to the opening operation as quickly as possible. For this reason, in this embodiment, when closing the door, under certain conditions, the operation of the vehicle door RD is switched from the closing operation to the opening operation with priority over the cooperation between the vehicle side and the ground side.

[0036] Hereinafter, with reference to the flowchart shown as FIG. 4, an example of a series of operations when, during the closing of the vehicle door in the home door control device 100 of the present embodiment, an operation to open the vehicle door is performed after the start of closing the vehicle door will be described.

[0037] For example, in a train stopped at a station, when it is confirmed that the process for departure has started, in the on-vehicle device 50 among the home door control devices 100, various operation processes are started to close the vehicle door RD (step S201). Thereafter, when an operation to open the vehicle door RD for some reason, that is, an activation of a vehicle door opening command by the conductor door switch 54 is performed (step S202), it is confirmed whether there is a vehicle door opening signal (step S203). As a typical example where the operation of step S202 is performed, when it is assumed that pinching occurs due to running and boarding as described above, in step S203, it is considered that there is a vehicle door opening signal (step S203: Yes). In this case, the on-vehicle device 50 immediately starts the operation of opening the vehicle door without waiting for a response from the ground side (step S204). As described above, a quick response can be made when it is assumed that urgency is required such as the occurrence of pinching.

[0038] On the other hand, when it is determined in step S203 that there is no vehicle door opening signal (step S203: No), that is, when it is not assumed that urgency is required, the on-vehicle device 50 performs the door opening process in the same procedure as in the normal case. That is, the on-vehicle device 50 waits for a response from the ground side and performs the door opening process. Specifically, first, when the operation of step S202 is performed, in parallel with the determination process of step S203, processes corresponding to steps S101 to S103 and S105 in FIG. 3 are performed (steps S205 to S208). Among these, waiting for the reception of the door opening ACK shown in step S207, the operation of opening the vehicle door is started (step S204). That is, in the above case, when there is no vehicle door opening signal when the vehicle door opening command is activated, the vehicle door opening is started after waiting for a response from the ground side to the home door opening command.

[0039] Hereinafter, with reference to the flowchart shown as FIG. 5, an example of a series of operations will be described for the case where, among the closing of the vehicle door in the home door control device 100X of the comparative example illustrated in FIG. 2, an operation for opening the vehicle door is performed after the start of the closing of the vehicle door.

[0040] In the example shown in FIG. 5, even when an operation for opening the vehicle door RD is performed after the start of the closing of the vehicle door RD (steps S301, S302), since there is no process based on whether there is a vehicle door opening signal, the opening processes corresponding to steps S101 to S103 and S105 in FIG. 3 are performed (steps S303 to S305 and S307), and after waiting for the reception of the opening ACK shown in step S305, the operation of opening the vehicle door is started (step S306). That is, in the case of the comparative example, a prompt response corresponding to an emergency situation as in the case of the present embodiment cannot be made.

[0041] As described above, the home door control device 100 of the present embodiment performs an opening / closing operation in cooperation with the vehicle door RD and the home door PD. When there is a vehicle door opening signal when the vehicle door opening command is activated, the vehicle door opening is started by giving priority to the vehicle door opening command over the cooperation between the doors. Thereby, even though the home door control device 100 performs an opening / closing operation in cooperation with the vehicle door RD and the home door PD, in an emergency situation such as when pinching occurs in the vehicle door RD, a prompt response, that is, the vehicle door can be opened.

[0042] 〔Second Embodiment〕 Hereinafter, an example of the home door control device of the second embodiment will be described with reference to FIG. 6 and the like. Note that the present embodiment is a modification of the home door control device 100 of the first embodiment, and is the same as the case of the first embodiment except for differences in the communication mode and the configuration for performing communication. Therefore, for example, regarding the configuration of each part, refer to the matters described in the first embodiment as necessary, and detailed descriptions of each configuration and the like will be omitted.

[0043] Next, with reference to the block diagram shown as FIG. 6, a configuration example of the home door control device 100 according to the present embodiment will be described. Note that FIG. 6 is a diagram corresponding to FIG. 1. As is clear from comparing FIG. 6 with FIG. 1, in the present embodiment, the configuration in the communication signal processing unit 52a among the on-vehicle side wireless cooperation devices 52 is different. That is, there are differences in the signal processing for cooperation based on wireless communication between the ground side and the on-vehicle side.

[0044] In the first embodiment, at the time of switching the door opening process after the start of the door closing process, the ground side process is performed in parallel with the on-vehicle side process. For this reason, regardless of the selection of the door opening process (opening of the vehicle door RD) accompanying the urgency determination result on the on-vehicle side, ultimately, the door opening process is also performed on the ground side, that is, the opening process of the home door PD is also performed along with the opening process of the vehicle door RD.

[0045] On the other hand, in the present embodiment, in the case of an emergency such as when pinching occurs in the vehicle door RD, it is different from the case of the first embodiment in that the home door PD is not opened. More specifically, when there is a vehicle door opening in progress signal when the vehicle door opening command is activated, the home door opening command is not output from the on-vehicle side to the ground side, and the home door is maintained in the closed state. In this case, for example, in an emergency such as when pinching occurs in the vehicle door RD due to a dash boarding, the vehicle door RD is immediately opened to deal with the pinched state, while the home door PD is maintained in the closed state, thereby avoiding a situation where, for example, the home door PD is fully opened and another new dash boarding occurs.

[0046] As is clear from comparison with FIG. 1, in the on-vehicle device 50 of the home door control device 100 shown in FIG. 6, the configuration of the cooperation signal processing unit 52a among the on-vehicle side wireless cooperation devices 52 is different. More specifically, the cooperation signal processing unit 52a is configured by a combination of a cooperation AND circuit Caa and a cooperation NOT circuit Cnn. The cooperation NOT circuit Cnn receives an input of a vehicle door opening signal from the vehicle door control device 51 and its output destination is connected to the input of the cooperation AND circuit Caa. The cooperation AND circuit Caa receives inputs regarding the output from the cooperation NOT circuit Cnn and the vehicle door opening command branched from the conductor's door switch 54, and is a circuit that determines whether to transmit a home door opening command. That is, in the case of the above aspect, in the cooperation signal processing unit 52a, when there is only an input of a vehicle door opening command from the conductor's door switch 54, a corresponding home door opening command is transmitted to the ground side. However, when there are both a vehicle door opening command from the conductor's door switch 54 and a vehicle door opening signal, the home door opening command is not (not output) transmitted. Note that the in-vehicle signal processing unit 52b is the same as in the case of FIG. 1. When there are both a vehicle door opening command and a vehicle door opening signal, an output signal is transmitted accordingly to cause the vehicle door control device 51 to perform opening control of the vehicle door RD.

[0047] Hereinafter, with reference to the flowchart shown as FIG. 7, an example of a series of operations when an operation to open the vehicle door is performed after the start of closing the vehicle door in the home door control device 100 of the present embodiment will be described. Note that FIG. 7 corresponds to FIG. 4.

[0048] In the present embodiment, when an operation to open the vehicle door RD is performed after the closing of the vehicle door RD is started (steps S401, S402), it is confirmed whether there is a vehicle door opening signal (step S403) in the same manner as in the case of FIG. 4. However, it is different from the case of FIG. 4 in that a home door opening command is not immediately transmitted from the on-vehicle device 50 to the ground device 10.

[0049] In step S403, when it is determined that there is a signal indicating that the vehicle door is being opened (step S403: Yes), without waiting for a response from the ground side, the operation of opening the vehicle door is started (step S404). Also, in this case, since there is an activation of the vehicle door opening command and a signal indicating that the vehicle door is being opened, in the cooperation AND circuit Caa, the home door opening command will not be transmitted. That is, on the ground side, the home door PD will not open, and only the vehicle door RD will open.

[0050] On the other hand, in step S403, when it is determined that there is no signal indicating that the vehicle door is being opened (step S403: No), for the first time here, the opening process is started in the same procedure as in the normal case. That is, in the cooperation AND circuit Caa, the home door opening command is transmitted (step S405), and in response to this, an opening ACK is transmitted from the ground side (step S406), received on the vehicle side (step S407), and the operation of opening the vehicle door RD is started, and a normal series of processes are performed. Also, with the transmission from the vehicle side to the ground side in step S406, on the ground side, that is, in the ground device 10, the operation of opening the home door PD is started (step S408). That is, in this case, not only the vehicle door RD but also the home door PD will open.

[0051] As described above, also in the home door control device 100 of the present embodiment, while the vehicle door RD and the home door PD cooperate to perform the opening and closing operations, in an emergency situation such as when pinching occurs in the vehicle door RD, a quick response, that is, opening the vehicle door, can be performed. Furthermore, in the present embodiment, when there is a signal indicating that the vehicle door is being opened when the vehicle door opening command is activated, by not outputting the home door opening command from the vehicle side to the ground side and maintaining the home door PD in the closed state, in a situation where pinching occurs, etc., the occurrence of further rushing into the vehicle from the home door PD can be avoided.

[0052] 〔Third Embodiment〕 Hereinafter, an example of the home door control device according to the third embodiment will be described with reference to FIG. 8 and the like. Note that this embodiment is a modification of the home door control device 100 according to the first and second embodiments, and is the same as the cases of the first and second embodiments except for differences in the communication mode and the configuration for performing communication. Therefore, for example, regarding the configuration of each part, refer to the matters described in the first and second embodiments as necessary, and detailed descriptions of each configuration and the like will be omitted.

[0053] Hereinafter, a configuration example of the home door control device 100 according to this embodiment will be described with reference to the block diagram shown as FIG. 8. Note that FIG. 8 corresponds to FIGS. 1 and 6. As is clear from comparing FIG. 8 with FIG. 6, in this embodiment, as shown surrounded by the broken line DD1, in addition to the vehicle door opening signal branching to the cooperation NOT circuit Cnn side as in the case of FIG. 6, it also branches to the external output side. In this case, the vehicle door opening signal is transmitted directly to the ground side via the cooperation signal processing unit 52a of the on-vehicle side wireless cooperation device 52 and further via the radio 53. In this regard, the configuration is different. That is, there are differences in the signal processing for cooperation based on wireless communication between the ground side and the on-vehicle side. In particular, in the above case, by transmitting the vehicle door opening signal to the ground side, on the ground side, with regard to the opening of the home door PD, processing and operations are performed so as to correspond to the vehicle door opening signal.

[0054] For example, in the second embodiment, in the event of an emergency such as when pinching occurs in the vehicle door RD, the vehicle door RD is immediately opened to deal with the pinched state, while the home door PD is maintained in the closed state. On the other hand, in this embodiment, on the ground side, by grasping which vehicle door RD the vehicle door opening signal is activated in, for example, as shown in FIG. 9, among the plurality of vehicle doors RD provided in the train, only the home door PDα corresponding to the vehicle door RDα to which the vehicle door opening signal applies can have its operation controlled. That is, on the ground side, it becomes possible to select which of the plurality of home doors PD should be opened, or delay the timing of home door opening. As a result, it becomes possible to limit the opening operation within the necessary range, or provide an appropriate difference between the timing of vehicle door opening and the timing of home door opening.

[0055] In this embodiment, in the cooperation signal processing unit 52a, by the combination of the cooperation AND circuit Caa and the cooperation NOT circuit Cnn, similar to the case of the second embodiment, in the cooperation AND circuit Caa, when only the vehicle door opening command is input among the vehicle door opening command and the vehicle door opening signal, the corresponding home door opening command is transmitted to the ground side. However, when both the vehicle door opening command and the vehicle door opening signal are input, the home door opening command via the cooperation AND circuit Caa will not be transmitted. On the other hand, separately from this, when there is a vehicle door opening signal, regardless of the presence or absence of the vehicle door opening command, information about the vehicle door opening signal is transmitted to the ground side without passing through the cooperation AND circuit Caa. Here, not only the information about the vehicle door opening signal transmitted via the cooperation AND circuit Caa but also the information about the vehicle door opening signal transmitted without passing through the cooperation AND circuit Caa is to be treated as a home door opening command (a command to open some of the home doors PD).

[0056] That is, in the case of the above configuration, there are two types of home door opening commands transmitted from the upper side of the vehicle to the ground side. Specifically, there are a home door opening command transmitted along with the activation of the vehicle door opening command from the conductor door switch 54 (a command not accompanied by the activation of the vehicle door open signal), and a home door opening command transmitted along with the activation of the vehicle door open signal regardless of the presence or absence of the vehicle door opening command (a command accompanied by the activation of the vehicle door open signal). The former is the same home door opening command as the case described so far, while the latter is a home door opening command unique to this embodiment. In addition, when the latter home door opening command is transmitted, it can also be said that when the vehicle door open signal was present together with the home door opening command, it was output from the upper side of the vehicle to the ground side. In this embodiment, in the above case, on the ground side, means such as selecting the home door PD to be opened or delaying the timing of home door opening can be taken.

[0057] Hereinafter, with reference to the flowchart shown as FIG. 10, an example of a series of operations will be described for the case where, among the closing of the vehicle doors in the home door control device 100 of this embodiment, an operation to open the vehicle doors is performed after the start of closing the vehicle doors. Note that FIG. 10 corresponds to FIGS. 4 and 7.

[0058] In this embodiment, when an operation to open the vehicle door RD is performed after the closing of the vehicle door RD has started (steps S501, S502), as in the case of FIG. 7, it is confirmed whether there is a vehicle door open signal (step S503), while the transmission of the home door opening command from the on-vehicle device 50 to the ground device 10 is not immediately performed.

[0059] In step S503, when it is determined that there is a signal indicating that the vehicle door is being opened (step S503: Yes), without waiting for a response from the ground side, the operation of opening the vehicle door is started (step S504). On the other hand, in this case, since there is a signal indicating that the vehicle door is being opened, in parallel with step S504, a home door opening command associated with the activation of the vehicle door opening signal is issued from the vehicle upper side to the ground side (step S505). Accordingly, on the ground side, for example, home door opening (opening only the necessary locations) is performed, such as opening only the home door PDα corresponding to the corresponding vehicle door RDα (step S506). Note that in this case, since there is an activation of the vehicle door opening command and a signal indicating that the vehicle door is being opened, in the cooperation AND circuit Caa, the home door opening command will not be transmitted.

[0060] In step S503, when it is determined that there is no signal indicating that the vehicle door is being opened (step S503: No), the door opening process is started in the same procedure as in the normal state. That is, in the cooperation AND circuit Caa, a home door opening command is transmitted (step S507). In response to this, an opening ACK is transmitted from the ground side (step S508), received on the vehicle upper side (step S509), and a series of normal processes are performed, such as starting the door opening operation of the vehicle door RD. Also, with the transmission from the vehicle side to the ground side in step S507, on the ground side, that is, in the ground device 10, the door opening operations of all the home doors PD are started (step S510). That is, in this case, not only all the vehicle doors RD but also all the home doors PD will be in an open state.

[0061] As described above, even in the home door control device 100 of the present embodiment, while performing the opening and closing operations in cooperation with the vehicle door RD and the home door PD, in the case of an emergency such as when pinching occurs in the vehicle door RD, a prompt response, that is, opening the vehicle door, can be performed. Further, in the present embodiment, when there is a vehicle door opening signal when the vehicle door opening command is activated, by including the vehicle door opening signal in the home door opening command from the on-vehicle side to the ground side, for example, it becomes possible to take measures such as opening only some of the corresponding home doors PD.

[0062] 〔Others〕 Hereinafter, with reference to FIG. 11, the outline matters common to the above-described embodiments will be briefly summarized. FIGS. 11(A) and 11(B) are conceptual diagrams summarizing the configuration and operation of the home door control device 100. FIG. 11(A) shows the cooperation between the ground side and the on-vehicle side, and FIG. 11(B) shows the case where there is a mode that takes precedence over the above cooperation.

[0063] First, as shown in FIG. 11(A), and as described above, the home door control device 100 in each embodiment is all configured to include a ground device 10 responsible for the operation control of the home door PD and an on-vehicle device 50 responsible for the operation control of the vehicle door RD. With these, the vehicle door RD and the home door PD perform the opening and closing operations in cooperation. Then, as shown in FIG. 11(B), when a vehicle door opening command is activated in the on-vehicle device 50 and there is a vehicle door opening signal, the vehicle door opening is started with priority given to the vehicle door opening command rather than the cooperation between the above-described doors. Thereby, in the case of an emergency such as when pinching occurs in the vehicle door RD, a prompt response, that is, opening the vehicle door, can be performed as early as possible.

[0064] The present invention is not limited to the above-described embodiments, and can be implemented in various modes without departing from the gist thereof. Further, the above-described embodiments are examples, and can be appropriately changed and combined within a range where no contradiction occurs.

[0065] First, in the above embodiment, the vehicle door opening command is output by using the conductor's door switch 54 (for example, the conductor presses the switch). However, the vehicle door opening command can be issued in various manners. For example, in a mode of remotely managing the operation of each vehicle, it is also possible to adopt a mode in which the vehicle door opening command is issued from a management unit that performs overall management.

[0066] Also, in the above embodiment, various types of trains can be considered, and it may be composed of a plurality of vehicles. It is also possible to apply the present application to a single-car train.

[0067] Moreover, the invention shown in each of the above embodiments can be applied not only to trains but also to various transportation systems such as BRT, LRT, or monorails having vehicles.
