Abstract: A vehicle includes running wheels traveling on traveling road surfaces of tracks; a pair of position detection parts disposed at an interval in a width direction that output signals by detecting a distance from measured objects; a control unit controlling the amount of steering of the running wheels according to the signals from the position detection parts; and a steering mechanism steering the running wheels via the control unit. Each of the position detection parts outputs a signal having characteristics such that the output increases as the distance from the measured objects increases while an output change ratio is decreased in a range wherein the distance from the measured objects is not less than a predetermined value, and is configured such that, when the distance between one position detection part and the measured object is decreased, the distance between the other position detection part and the measured object is increased.

Abstract: A locomotive air brake control system that responds to penalty braking requests from external systems by applying a varying amount of train brake level based on monitored and calculated parameters in order to enforce a defined train condition. The system may include a minimum acceptable train braking, a condition to be achieved to prevent further application of train brakes, and a maximum train brake level to be applied in response to the request. Alternatively, the system may apply braking in stepped levels according defined thresholds for a train behavior variable of interest such as speed or deceleration. The system may be configured to incrementally apply and release train brakes during the adaptive penalty, and may also adjust the level of braking according to calculated braking capacity of the train.

Abstract: In order to avoid a collision between transport units, which are moving along a transport path of a transport assembly, and/or the collision of a transport unit with a barrier and/or the surpassing of a local speed limit, for at least one transport unit (TEi) it is preemptively determined if for the transport unit (TEi) a stopping maneuver (SMi) with a predetermined cinematic may be performed, without causing a violation of these safety requirements. In case of violation of a safety requirement, the stopping maneuver is effectively activated.

Abstract: A remote data backup system for a locomotive may include a communication unit on-board the locomotive configured to be communicatively coupled with an off-board server. The communication unit may be configured to transmit data to the off-board server and receive at least one of data, commands, and applications from the off-board server. The remote data backup system may also include a central processing module on-board the locomotive comprising a cab electronics system configured to receive and store on-board equipment operational data from outputs of one or more of machine gauges, indicators, sensors, and controls in an on-board memory, process and integrate the received equipment operational data, receive additional equipment operational data and one or more control command signals from the off-board server, and communicate commands based on the equipment operational data and the received control command signals. The system may also perform a self-check upon startup of the locomotive to determine whether equipment operational data is present in the on-board memory, and request a download of previously uploaded data from the off-board server if the self-check determines that no equipment operational data is present in the on-board memory.
