Vehicles walking in the same direction are divided into each other while walking In the non-patent document 1, the non-patent document 1 describes that the distance between the vehicle that is the preceding vehicle and the speed of the preceding vehicle is determined so that the distance from the preceding vehicle is the distance from the known vehicle. Moreover, the speed of the preceding vehicle is used as the way to limit the speed of the switch, and it is possible to secure the walking distance corresponding to the distance and the speed limit. Moreover, even if the following vehicle approaches the preceding vehicle in a state of high speed, the subsequent vehicle can control the speed of the subsequent vehicle itself by using the brake to fall below the speed corresponding to the distance and the speed limit.

Further, as means for measuring the distance from the preceding vehicle in the subsequent vehicle, for example, a method of calculating the relative speed from the measurement time difference and the amount of change in the distance after the distance is measured by the distance measuring means using the laser, and the relative speed and subsequent The method of calculating the speed of the preceding vehicle by the speed of the vehicle itself.

In a vehicle that performs split control, the preceding vehicle can receive information from the digital device and walk. On the other hand, the subsequent vehicle performs control that does not follow the information from the semaphore device because of the control of walking at intervals shorter than the train interval caused by the semaphore device. Therefore, during the division control, when the preceding vehicle performs the brake control based on the information from the digital device or the information from the bridge, the braking force of the following vehicle is insufficient due to the abnormality of the braking device of the subsequent vehicle or the like. When it is played, there is the possibility that vehicles will collide with each other.

In order to solve the above problems, the present invention is directed to a brake control method for a railway vehicle in which a preceding vehicle and a subsequent vehicle are divided during traveling, characterized in that, when the preceding vehicle and the following vehicle are divided, the brake is performed in accordance with the subsequent vehicle. The force information is used to determine whether there is an abnormality in the braking device of each subsequent vehicle. When it is determined that there is no abnormality, the distance between the preceding vehicle and the following vehicle is pulled to a predetermined distance or more.

According to the present invention, by the above-described means, when a stop command is given to the preceding vehicle of the train in the split control, the train collision that affects the safety of the passenger or the vehicle failure can be avoided.

Hereinafter, the embodiment will be described using the drawings.

[Example 1]

In the present embodiment, a train composed of a plurality of vehicles that are mixed by a connector (not shown) will be described. When the train is cut away from the connector, the train is divided into trains, and each train is transferred to the section control. (block control) segmentation controlled vehicle system.

Fig. 1 is an example of a configuration diagram of a railway vehicle system of the present embodiment. The preceding vehicle 101 and the subsequent vehicle 102 perform division control for performing division while walking the track 103. In the present embodiment, as an example of compiling a train, two vehicles of the preceding vehicle 101 and the following vehicle 102 are described as an example. However, the present invention is not limited to two trains, and is composed of three or more vehicles. Trains are also available.

The preceding vehicle 101 includes a preceding vehicle division control device 111, a preceding vehicle information transmission device 112, a preceding vehicle brake device 113, and division control range information 114. Further, the following vehicle 102 has a subsequent vehicle division control device 121, a subsequent vehicle information transmission device 122, a subsequent vehicle brake device 123, and division control range information 114. The first vehicle information transmission device 112 accepts the preceding vehicle split control device The indication of 111 is sent to the subsequent vehicle information transmitting device 122 to periodically transmit the inter-vehicle transmission information 131. The subsequent vehicle information transmitting device 122 receives the inter-vehicle transmission information 131 and gives the content to the subsequent vehicle segmentation control device 121.

Among them, the preceding vehicle brake device 113 and the subsequent vehicle brake device 123 are devices that output a braking force according to a brake command from a kiosk device such as a pilot bridge, an ATS, etc., which is a mechanical brake or an electric brake. Composition.

Further, the preceding vehicle information transmitting device 112 and the subsequent vehicle information transmitting device 122 can be realized by, for example, using laser light communication, wireless communication using spatial waves, communication using LCX cable, or the like.

The preceding vehicle 101 and the subsequent vehicle 102 determine the division control to start walking by the preceding vehicle division control device 111 and the subsequent vehicle division control device 121 by the division control range specifying means 104 or the division control range information 114. The information held in the division control range information 114 includes information on the vehicle number of the preceding vehicle and the subsequent vehicle, the start of the division control, and the position at which the division control ends. An example of the split control range information 114 is shown in FIG. In addition, the vehicle number may not be repeatedly assigned to the unique ID of each vehicle like a train number. Moreover, the information of the position is the distance from the reference position on the track 103 corresponding to the information of the preceding vehicle 5001 and the subsequent vehicle 5011 of FIG. 2, or the information corresponding to the preceding vehicle 5003 and the subsequent vehicle 5051 of FIG. The location of the longitude information is better. Others may also be information that can identify the location without any discrepancies.

The division control range specifying means 104 is a device which is disposed at a predetermined position on the track like a ground member of a railway, and transmits arbitrary information to the vehicle passing through the position. It is preferable that the division control range specifying means 104 is provided with one or more on the track 103. When the division control range specifying means 104 is provided at the division control start position and the division control range specifying means 104-1 is provided at the end position of the division control, the division control range specifying means 104 starts division control for the passing train transmission. News. Similarly, the division control range specifying means 104-1 transmits the information of the end division control to the passing train.

Further, there is a case where the combination division control range specifying means 104 and the division control range information 114 are used. In this case, the division control range information 114 associates and holds the name of the division control range specifying means 104 provided at the position of the coincident track 103 with respect to at least one of the start position or the end position of the division control. Next, the division control range specifying means 104 provided at the position of the track 103 transmits the name of the division control range specifying means 104 to the preceding vehicle 101 and the subsequent vehicle 102 passing through the position. The preceding vehicle 101 and the subsequent vehicle 102 use the received name and division control range information 114 to determine whether to start or end the division control. As information about the preceding vehicle 5002 and the subsequent vehicle 5101 in FIG. 2, it is indicated that the division control range specifying means 104 is provided at the start position of the division control, and the division control range is set at the end position of the division control. The device 104-1 is designated and the name is kept. Further, the information transmitted by the division control range information 114 and divided by the control area specifying means 104 may be a unique ID in addition to the name.

As a result, the preceding vehicle 101 or the following vehicle 102 travels on the track 103, and when the division control start position held by the division control range information 114 or the division control range designation device 104 is started, the division control is started. Next, when the division control end position held by the division control range information 114 is passed or when the division control range specifying means 104-1 is passed, the division control is ended.

When the division control is started, the subsequent vehicle 102 uses the distance to the preceding vehicle 101 and the speed of the preceding vehicle 101 and the speed of the subsequent vehicle 102 itself to securely transfer the divided vehicles to a distance greater than a predetermined distance. Walking control. The walking at this time can be achieved by, for example, the technique described in Patent Document 1 or 2. Specifically, as in the case of the patent document 1, when the preceding vehicle applies the brake, the vehicle is prevented from colliding with the preceding vehicle by applying the brake from the subsequent vehicle, or is as in Patent Document 2. , controlling the relative speed of the preceding vehicle and the subsequent vehicle.

The description relates to the case where the preceding vehicle 101 is braked in the split control. The braking operation of the preceding vehicle brake device 113 is, for example, a case where a brake command is caused by a sign protection device such as ATS or a driver who has confirmed an obstacle in front of the approach, and manually inputs a brake command from the driver's seat. occasion. Braking action in split control Incidentally, this is performed by the brake command output from the preceding vehicle division control device 111 for the division processing.

The processing sequence of the division control by the preceding vehicle division control device 111 will be described using FIG. First, when the division control start position held by the division control range information 114 or the division control range designation means 104 is passed, the division 1001 is started. Next, the connector is released, and a process 1002 of canceling the mixing with the subsequent vehicle is performed. Next, based on the information on the braking generating force of the subsequent vehicle 102, the braking device of the following vehicle is subjected to a process 1003 for determining whether or not there is an abnormality. The details of the processing will be described later. Here, the subsequent vehicle judges that there is no abnormality in the braking device of the subsequent train, and the result can be received by the information transmitting device 112.

When it is determined that the braking of the following vehicle is abnormal, the preceding vehicle division control device 111 performs the process of reconnection 1008. Specifically, the instruction for reconnecting the subsequent vehicle transmission controls the speed of the vehicle itself according to the inter-vehicle distance of the preceding vehicle and the following vehicle or the relative speed of the following vehicle, so as to be close to the subsequent train, and then connected with the following vehicle. The hash caused by the device proceeds to the end of the split 1007.

When it is determined that there is no abnormality in the braking of the following vehicle, the process 1004 of expanding the inter-vehicle distance of the preceding vehicle and the following vehicle to a predetermined distance or more is performed. In particular, for example, the preceding vehicle performs inertial movement or acceleration or deceleration of the braking force that is weaker than the subsequent vehicle, thereby expanding the inter-vehicle distance. Next, a process 1005 of confirming whether the distance between the preceding vehicle and the subsequent vehicle is greater than or equal to the specified distance is performed. In the not yet specified distance When it is the above, it returns to the brake abnormality determination process 1003 of the following vehicle. In the case where the distance from the workshop of the following vehicle is more than a certain value, as a process of subsequent vehicle shifting to the section control, the preceding vehicle performs the distance measurement with the subsequent vehicle, the braking command for the following vehicle, and the processing of the interrupt period communication. 1006, proceed to the end of the split 1007.

Next, the processing sequence of the division control by the subsequent vehicle division control device 121 will be described using FIG. First, when the division control start position held by the division control range information 114 or the division control range designation means 104 is passed, the process of starting the division 1101 is performed. The determination of the start of the division may be performed by receiving the information of the division start from the preceding train through the information transmission device 122.

Next, the connector is released, and the process 1102 of canceling the mixing with the preceding vehicle is performed.

Next, the subsequent vehicle division control device 121 performs a deceleration processing 1103 for outputting a brake command of the specified braking force to the subsequent vehicle brake device 123. Next, the information transfer device 122 performs a process 1104 of confirming whether or not the reconnection command from the preceding vehicle has been received. When the reconnection command is received, the subsequent vehicle performs the reconnection process 1111 with the preceding vehicle in accordance with the instruction. Specifically, the speed of the vehicle itself is controlled according to the distance and relative speed of the preceding vehicle, so that it is close to the preceding train, and the hybrid with the preceding vehicle is used as a connector.

If there is no reconnection command yet, then proceed A process 1105 of confirming receipt of the brake command is confirmed. When the brake command is received, if the brake command is a stronger braking force than the brake currently being implemented, the subsequent vehicle branching control device 121 performs braking to comply with the commanded braking force, and the subsequent vehicle is passed. The brake device 123 is applied to the process 1110 of the vehicle itself.

When the brake command from the preceding vehicle has not been received, the process 1106 is performed. The preceding vehicle and the following vehicle periodically transmit the shop floor transmission information 131 via the information transfer devices 112, 122. At process 1106, a process 1106 of confirming whether communication with the preceding vehicle has been interrupted for a certain period of time or more is performed. When the vehicle is interrupted for a certain period of time or longer, the following vehicle is used as the safety side control, and the braking force that is not chased even when the maximum braking force applied to the preceding vehicle is applied is applied to the vehicle itself 1110.

When the communication with the preceding vehicle has not been interrupted, a process 1107 of confirming whether the workshop of the preceding vehicle and the following vehicle is equal to or greater than the designated distance is performed. When it is not yet the specified distance, the process 1103 of deceleration using the brake is returned.

When the plant of the preceding vehicle is a predetermined distance or more, the subsequent vehicle proceeds to the process 1108 of the zone control, and proceeds to the division completion 1109.

In the process 1003 of determining whether there is an abnormality in the braking device of the following vehicle, it is desirable to keep the inter-vehicle distance of the preceding vehicle and the following vehicle within a specified distance. In the case where the vehicle is applied with a very close distance (0 to 5 m), even if the braking of the subsequent vehicle 102 is delayed In the case of being late, the increase in the relative speed due to the deceleration of the preceding vehicle is suppressed to within a certain value. Therefore, even if the vehicle is in contact, the collision force due to the collision is the same as that occurring during the normal mixing, and does not affect the safety of the passenger or the vehicle failure. The measurement of the distance between the preceding vehicle and the following vehicle is applicable to a known technique such as ranging due to laser or walking distance calculation due to a speed generator.

In the process 1003 caused by the preceding vehicle division control device 111, in order to determine whether there is an abnormality in the braking device of the following vehicle, it is necessary for the preceding vehicle to confirm the deceleration speed of the subsequent vehicle. As a method of confirming the deceleration of the following vehicle, the moving distance of the time unit of each subsequent vehicle is measured by a known technique such as ranging by laser or distance calculation by a speed generator. Confirm the deceleration speed. Further, when the air brake is used, the information on the pressure sensor measurement value of the brake pipe of the subsequent vehicle may be transmitted to the preceding vehicle to confirm the deceleration state of the subsequent vehicle. The preceding vehicle determines the deceleration speed of the following vehicle for a certain period of time, and the braking force occurring in the subsequent vehicle is judged to be insufficient as compared with the braking force specified in the processing 1103 of the subsequent vehicle division control device. In the case (brake device failure, regeneration failure, coasting, etc.), it can be judged that the brake is abnormal.

The subsequent vehicle is decelerating at a predetermined braking force using a predetermined braking force to perform the deceleration processing 1103, but it is expected that the closer the distance to the preceding vehicle is, the more the vehicle follows. Strong braking force to slow down. When the preceding vehicle is braked, the closer the distance to the preceding vehicle is, the more the braking delay applied by the subsequent vehicle is, the higher the ability of the preceding vehicle to contact the subsequent vehicle. The closer the distance is, the stronger the braking force is applied. Even if the preceding vehicle decelerates with the maximum braking force, the difference between the braking force and the subsequent vehicle becomes smaller, so the relative speed of the preceding vehicle and the following vehicle becomes smaller, and the cause can be avoided. Chasing delays in braking.

The process 1005 of confirming whether the distance between the preceding vehicle and the subsequent vehicle is greater than a certain value, and the measurement of the distance between the preceding vehicle and the subsequent vehicle in the processing 1106 may be applicable to the distance measurement due to laser or the speed generator A well-known technique such as a walking distance calculation, a vehicle position detection due to a track circuit, and the like.

When it is determined that the brake of the following vehicle is abnormal, in the reconnection process 1008 performed by the preceding vehicle, the preceding vehicle has the interruption division control for the subsequent vehicle command, and the subsequent vehicle is reconnected, and then proceeds to the division completion 1007. After the completion of the division, there is a possibility that a braking abnormality of the following vehicle occurs, and it is desirable that the preceding vehicle issues an emergency braking command to the following vehicle, and the vehicle itself also applies emergency braking to stop the vehicle. At the time of reconnection, the relative speed of the workshop distance control between the preceding vehicle and the following vehicle is controlled, and the acceleration and deceleration speed of each vehicle is controlled so that the relative speed during the mixing is below a certain value.

In FIG. 3, as the reconnection processing 1008, an example in which the process of mixing the preceding vehicle and the following vehicle is performed in the case where it is determined that the braking of the following vehicle is abnormal is described, but the braking of the following vehicle is determined. In the case of an abnormality, when the emergency braking of the following vehicle is normal, the vehicle may be stopped by the emergency braking in a state where the preceding vehicle and the following vehicle are not mixed. In this case, it is desirable that the following vehicle first applies emergency braking or the like to the preceding vehicle, and adjusts the timing of the braking between the vehicles so that the following vehicle cannot catch up with the preceding vehicle. If there is an abnormality in the emergency braking of the following vehicle, there is a possibility that the following vehicle collides with the preceding vehicle, and therefore it is desirable to perform the process of reconnecting the preceding vehicle and the following vehicle. Alternatively, in the case where it is determined that there is a brake abnormality of the following vehicle, if the emergency braking of the following vehicle is normal, the vehicle may not be decelerated first, and only the subsequent vehicle may be decelerated and stopped.

In the process 1004 of expanding the inter-vehicle distance between the preceding vehicle and the following vehicle, the preceding vehicle is operated by inertial movement or accelerated to expand the inter-vehicle distance of the vehicle following the deceleration. Alternatively, it is also possible to apply a brake that is weaker than the braking force of the following vehicle to the preceding vehicle to increase the distance of the workshop. Further, it is also possible to perform a process of using a subsequent vehicle to continue a certain braking force. It is desirable that the preceding vehicle and the subsequent vehicle communicate with each other in the processing state and the traveling state between the processing 1006 of shifting the segment control after the execution of the blending cancel processing 1002 and the processing 1102, and the processing until the processing 1108. The preceding vehicle is in the form of a brake command issued to the following vehicle as necessary. After shifting to the zone control, a known zone control based on the stop position or the speed limit is performed.

In the process 1103 of the subsequent vehicle issuing a brake command to the vehicle itself, the distance from the workshop of the preceding vehicle is a specified distance or more. It is expected that the following vehicle will decelerate with a certain braking force. The more the braking force of the subsequent vehicle is closer to the subsequent vehicle, the communication delay to the following vehicle may occur even if the braking of the preceding vehicle is applied, and the difference in braking force between the preceding vehicle and the following vehicle may be reduced. Can reduce the possibility of collision. The braking force of the following vehicle at this time is calculated from the maximum braking force of the preceding vehicle and the desired maximum communication delay.

In the above description, the command for the preceding vehicle and the following vehicle is performed by the preceding vehicle, but it is also possible that the following vehicle or the above-ground equipment becomes the main body to give an instruction.

According to the first embodiment described above, the preceding vehicle 101 confirms that there is no abnormality in the braking of the subsequent vehicle 102 via the process 1003 after the release is canceled, and then performs a process 1004 of expanding the inter-vehicle distance from the subsequent vehicle 102 to a predetermined distance or more. Therefore, in the case where the brake of the following vehicle is confirmed to be abnormal, the distance between the workshops is separated by a specified distance or more, and in the state where the distance of the workshop is more than the specified distance, when the preceding vehicle applies the brake, the following vehicle It is also possible to apply a brake to become a collision that can avoid the safety of the passenger or the breakdown of the vehicle.

Moreover, before determining the braking abnormality of the following vehicle, in the case where the preceding vehicle applies the braking, the inter-vehicle distance is a state in which the specified distance is not reached, and the relative speed of the preceding vehicle and the following vehicle is reduced, if, even if the braking of the following vehicle is performed In the event of a collision, the collision force due to the collision becomes the same as the collision occurring during the normal mixing, and the safety of the passenger or the vehicle failure is not will affect.

Further, in the first embodiment, as the reconnection processing 1008, when it is determined that the braking of the following vehicle is abnormal, the process of reconnecting the preceding vehicle and the following vehicle is performed. Alternatively, instead of this, in a state where the preceding vehicle and the following vehicle are not mixed, the process of stopping each vehicle via the emergency braking, or the process in which the preceding vehicle does not decelerate, and only the subsequent vehicle decelerating and stopping is performed. For this reason, it is possible to make the subsequent vehicle having the brake abnormality not stop safely with the collision of the preceding vehicle that affects the safety of the passenger or the vehicle.

Further, when the stop command from the number device or the like is given to the preceding train and the subsequent train in the division control, the stop command is first received by the train, and the order from the preceding train to the subsequent train becomes necessary. Therefore, when the preceding trains perform the brake control during the division control in which the vehicles traveling in the same direction are performing the division while traveling, the subsequent vehicles cannot be sufficiently decelerated due to the delay of the communication or the like, and the subsequent brake control of the train is delayed. The possibility of chasing the first vehicle. Here, as in the first embodiment, the above-described configuration of the processing 1003 or 1004 is added, and further, after the processing 1106, the subsequent vehicle 102 performs the braking operation when the communication from the preceding vehicle 101 is interrupted for a predetermined time or longer. In the case where the preceding vehicle applies the brake, even if the braking command to transmit the information transmitted as the workshop to the subsequent vehicle is interrupted for more than a certain period of time, the safety or the vehicle failure that affects the passenger can be avoided. collision.

Here, after the time when the preceding vehicle transmits information to the following vehicle, the following vehicle performs a braking operation, and when the preceding vehicle receives the braking action of the following vehicle from the preceding train, the preceding vehicle performs the braking operation, and the vehicles can be avoided. The collision is caused by the time from when the preceding vehicle receives the brake command until the brake control is performed, and there is a possibility that the preceding vehicle collides with the obstacle ahead. However, in the first embodiment, as described above, the subsequent vehicle 102 performs the braking operation as the safety side control in the case where the communication from the preceding vehicle 101 is interrupted via the processing 1106, and the preceding vehicle does not have to wait for the subsequent vehicle. The information of the braking action can also be applied to the brake, which becomes the time required to reduce the brake control of the preceding vehicle.

[Example 2]

In the first embodiment, the brake abnormality of the following vehicle is confirmed after the unmixing is cancelled. In the second embodiment, a control method for canceling the blending after confirming the brake abnormality of the subsequent vehicle will be described. In the second embodiment, a portion different from the first embodiment will be described, and the other portions are the same as those in the first embodiment.

The processing procedure of the division control by the preceding vehicle division control device 111 in the second embodiment will be described using FIG. First, in the same manner as in the first embodiment, the division start 2001 is judged. Then, in a state in which the preceding vehicle and the subsequent vehicle are mixed, based on the information on the braking generating force of the following vehicle, it is determined whether the braking device of the following vehicle has an abnormality. 2002.

When it is determined that the braking of the following vehicle is abnormal, and before the mixing with the subsequent vehicle is released, the preceding vehicle performs a process 2009 for interrupting the subsequent vehicle instruction division, and the division is completed. After the release is canceled, the preceding vehicle transmits an instruction to reconnect the subsequent vehicle, and the preceding vehicle controls the speed of the vehicle itself according to the inter-vehicle distance or relative speed of the subsequent vehicle, and performs reconnection processing with the subsequent vehicle 2010, proceeding to The segmentation ends in 2007.

When it is judged that there is no brake abnormality, the process 2003 of canceling the mixing with the subsequent vehicle is performed. Next, a process 2004 of expanding the inter-vehicle distance between the preceding vehicle and the following vehicle is performed. Next, a process 2005 of confirming whether the distance between the preceding vehicle and the subsequent vehicle is greater than or equal to the specified distance is performed. When it is not already the specified distance or more, it returns to the brake abnormality determination process 2002. When the distance from the inter-vehicle of the following vehicle is equal to or greater than the specified distance, the preceding vehicle performs the process of shifting to the zone control 2006, and proceeds to the division completion 2007.

Next, the processing sequence of the division control by the subsequent vehicle division control means 121 will be described using FIG. First, in the same manner as in the first embodiment, the division start 2101 is determined. Next, the subsequent vehicle performs a process 2102 of performing deceleration using the specified braking force. Next, a process 2103 of confirming whether or not the split interrupt command from the preceding vehicle has been received is performed. When the split interrupt command is received, the subsequent vehicle executes the process 2113 of performing the split interrupt in accordance with the command. Specifically, the process of not releasing the connector is performed.

When the split interrupt node command has not been received, the process 2104 of canceling the blending with the preceding vehicle is performed. Next, a process 2105 of confirming whether or not the reconnection command from the preceding vehicle has been received is performed. When the reconnection command is received, the reconnection process 2112 is performed. In a specific aspect, the following vehicle controls the speed of the vehicle itself according to the inter-vehicle distance or relative speed of the preceding vehicle according to the instruction, so as to make it close to the preceding train, and perform the mixing due to the connector.

When the reconnection command has not been received, next, a process 2106 of confirming whether or not the brake command has been received is performed. When the brake command is received, if the command is a stronger braking force than the brake currently being implemented, the subsequent vehicle performs a process 2111 of applying the brake complying with the commanded braking force to the vehicle itself.

When the brake command from the preceding vehicle has not been received, it is determined whether or not the communication with the preceding vehicle has been interrupted for a certain period of time or longer 2107. When the vehicle is interrupted for a certain period of time or longer, the following vehicle is used as the safety side control, and the braking force that is not chased even when the maximum braking force applied to the preceding vehicle is applied is applied to the vehicle itself 2111.

When the communication with the preceding vehicle has not been interrupted, a process 2108 of confirming whether the workshop of the preceding vehicle and the following vehicle is equal to or greater than the designated distance is performed. When it has not reached the predetermined distance or more, it returns to the process 2102 which uses a brake to decelerate. When the plant of the preceding vehicle is a predetermined distance or more, the subsequent vehicle proceeds to the process 2109 of the zone control, and proceeds to the division completion 2110.

In order to determine whether there is an abnormality in the braking device of the following vehicle, it is necessary for the preceding vehicle to confirm the deceleration speed of the subsequent vehicle. As a method of confirming the deceleration speed of the following vehicle, as in the first embodiment, the brake pipe of the following vehicle may be used in a known technique such as distance measurement due to laser or travel distance calculation due to a speed generator. The information of the pressure sensor's measured value is sent to the preceding vehicle to confirm the deceleration of the subsequent vehicle. Further, when the subsequent vehicle is decelerating, the sensor may measure the extension tension or the compressive force of the connector provided in the preceding vehicle and the subsequent vehicle, and estimate the braking force of the subsequent vehicle based on the measured value.

According to the division control sequence described in the second embodiment, it is possible to determine that the brake device of the following vehicle is abnormal before the release of the blending, and if it is determined that the abnormality has occurred, the division is interrupted before the release of the blending, and the train can be safely controlled.

Further, in the first embodiment, unlike the second embodiment, it is determined that the brake abnormality of the following vehicle is determined after the knocking is canceled, and the advantage of the brake abnormality can be determined based on the actual running state of the subsequent vehicle.

[Example 3]

In the first embodiment and the second embodiment, the processing in the case where the braking abnormality of the subsequent vehicle occurs during the division is shown. In the third embodiment, the determination of the brake abnormality added to the subsequent vehicles of the first embodiment and the second embodiment is added, and the processing in the case where the brake abnormality of the preceding vehicle occurs during the division is added.

The processing sequence of the division control by the preceding vehicle division control device 111 in the third embodiment will be described using FIG. First, in the same manner as in the first embodiment, the division start 3001 is determined. Next, in a state in which the preceding vehicle and the subsequent vehicle are mixed, based on the information on the braking generating force of the preceding vehicle and the following vehicle, a process 3002 of determining whether or not the braking device of the preceding vehicle or the following vehicle is abnormal is performed.

When it is determined that the braking of the preceding vehicle or the following vehicle is abnormal, and before the mixing with the subsequent vehicle is released, the preceding vehicle performs a process 3009 of interrupting the subsequent vehicle instruction division, and the division is completed. When the copy is released, the reconnection process 3010 is performed. Specifically, the preceding vehicle is an instruction to reconnect the subsequent vehicle transmission, and controls the speed of the vehicle itself according to the inter-vehicle distance or the relative speed of the preceding vehicle and the subsequent vehicle, so as to be close to the subsequent vehicle, and the connector is caused by the connector. Mixed. After that, proceed to the end of the split 3007.

When all of the preceding vehicle and the following vehicle are judged to have no brake abnormality, the process 3003 of canceling the mixing with the subsequent vehicle is performed. Next, a process 3004 of expanding the inter-vehicle distance between the preceding vehicle and the following vehicle is performed. Next, a process 3005 of confirming whether the distance between the preceding vehicle and the subsequent vehicle is greater than a specified distance is performed. When it is not more than the specified distance, the brake abnormality determination process 3002 is returned. When the distance from the inter-vehicle of the following vehicle is equal to or greater than the specified distance, the preceding vehicle performs the process 3006 of shifting to the zone control, and proceeds to the division completion 3007.

The processing sequence of the division control by the subsequent vehicle division control device 121 is the same as that shown in the second embodiment (see FIG. 6). For the same reason, the description is omitted.

As described above, in the same manner as in the second embodiment, a case has been described in which the process of determining whether or not the brake device is abnormal before the release of the mismatch is performed. However, the process of performing the determination may be performed after the splicing is released as in the first embodiment.

According to the division control sequence described in the third embodiment, it is possible to determine that the brake device of the preceding vehicle is abnormal, and if it is determined to be abnormal, the vehicle is maintained in a mixed state with the subsequent vehicle or is reconnected. Therefore, the following vehicle having no abnormality is used. The braking device can stop the preceding vehicle, so that it becomes safe to control the train.
