A system for vehicle management includes a control signal interface subsystem and a vehicle-mounted subsystem. Each of these subsystems includes an ultra-wideband (UWB) communications component. The subsystems communicate with each other through the UWB components. The vehicle mounted subsystem interfaces with a braking system of the vehicle. The vehicle mounted subsystem determines the distance between it and the control signal interface subsystem based on the time-of-flight of at least one communication between the subsystems. The vehicle-mounted subsystem can cause the braking system of the vehicle to activate if the distance between the vehicle-mounted subsystem and the control signal interface subsystem is less than a threshold.

A method is provided which protects persons in the vicinity of a high frequency (HF) field-emitting device, in particular a European train control system (ETCS) antenna of a rail vehicle. In order to be able to reliably protect persons from radiation that is detrimental to one's health, the device is held in or switched to an OFF state by an uplink for a limited period of time, the ON/OFF state being optically and/or acoustically signaled.

The limit information acquisition unit is configured to acquire limit information including speed limit information and the position information corresponding to the speed limit, from a vehicle speed limit unit that is configured to set the speed limits at a plurality of positions in order to achieve a predetermined deceleration completion speed at the speed limit start position. The current position acquisition unit is configured to acquire a current position of the vehicle. The current speed acquisition unit is configured to acquire a current speed of the vehicle. The travel curve generation unit is configured to generate a travel curve which satisfies the speed limit at each position obtained from the limit information according to the acquired limit information, the current position, and the current speed. The speed command unit is configured to generate a speed command according to the generated travel curve and the current position.

A system is provided that include at least one positioning system that can detect a location or position of a vehicle or a portion of a vehicle group that includes the vehicle, at least one sensor positioned on or associated with the vehicle that can generate sensor data of a determined parameter or condition, and a controller in communication with the sensor and the positioning system. The controller can determine that a hazard event has occurred based at least partially on sensor data, and can communicate a hazard event notification based at least in part on the location data and the sensor data to a remote server.

A course control device includes: an information acquisition unit to acquire information via any of wireless devices arranged along a track from a first station to a second station; and a course control unit to control the course of a course control target train based on the information acquired by the information acquisition unit. The course control unit prevents the course control target train from proceeding to the course in at least one of a case where at least one of the wireless devices is in a failure state, a case where an on-board device that is mounted in a preceding train preceding the course control target train on the track and controls the preceding train based on information acquired via the wireless devices is in a failure state, and a case where the preceding train is in a stationary state between the first station and the second station.

An example automated locomotive spotting system includes a locomotive having a tractive effort mechanism for moving the locomotive along a track, and a locomotive controller configured to control the tractive effort mechanism to move the locomotive along the track. The locomotive controller includes an odometer configured to monitor a distance traversed by the locomotive along the track. The locomotive controller is configured to receive a requested spotting distance value, and initiate movement of the locomotive along the track via the tractive effort mechanism. The locomotive controller is also configured to monitor, by the odometer, the distance traversed by the locomotive along the track, and inhibit movement of the locomotive in response to the monitored odometer distance indicating the locomotive has traversed the requested spotting distance.

The present invention is adapted to the technical field of communication, and provides a stop announcement system and a method thereof. The stop announcement system comprises: at least one platform beacon disposed on at least one stop site of a transportation means for identifying a position message of the stop site, and sending a message of position change according to the position change of the transportation means relative to the stop site; and at least one stop announcement device disposed on the transportation means for receiving the message of position change and sending a corresponding stop announcement message when the transportation means moves into a range of a preset communication distance of the at least one platform beacon; wherein the stop announcement message at least comprises a prompt message of entering into the stop site and/or a prompt message of stopping on the stop site and/or a prompt message of leaving the stop site. By virtue of this, the present invention achieves timely and accurately stop announcement in operation of the transportation means.

A train activates an emergency brake when a Station Loop Coil (SLC) used for a stop-position determination function to determine whether the train has stopped at a stop target in a terminal becomes unable to be detected (non-detected state) before the train is determined to have stopped at a stop-position by the stop-position determination function after the SLC has been detected. Thus, the train can be prevented from colliding with a car stop disposed at an end of a track as a result of overrunning. In the terminal protection, an emergency brake or a service brake is activated also when a reception duration during which the SLC continues to be detected reaches a predetermined threshold time period, or when a traveling position of the train reaches a disposed position of the SLC but the SLC is not detected.
