The present disclosure discloses a vehicle on-board controller centered train operation control system, the control system comprises intelligent vehicle controllers (IVOCs) provided on respective trains, the IVOC comprises a vehicle-vehicle communication device, an active identification device and a master control device. With such control system, rear-end train or more serious accidents may be avoided in case that there is a train without communication equipment or with equipment failure operation in front, or an obstruction impeding train operation appears in front of the train. Further, the control system provided by embodiments of the present disclosure enables a train to operate with a relatively high speed under the premise of safe operation, and improves operation efficiency and reliability.

The present invention provides an automatic train protection method, a vehicle on-board controller and a train based on vehicle-vehicle communication. The method includes: after a present train runs onto a main track, determining an OC with which the present train needs to establish communication; communicating, by the present train, with the OC to obtain train identifiers of all trains within the jurisdiction of the OC; respectively communicating, by the present train, with the train corresponding to each train identifier to obtain current running information of the train corresponding to each train identifier; identifying a front communication neighbor train of the present train; determining that no hidden train exists between the present train and the front communication neighbor train; and calculating current movement authority MA of the present train according to the current position information of the present train and of the front communication neighbor train.

An embodiment of the present disclosure provides a route resource controlling method, intelligent vehicle on-board controller and object controller. The method comprises: determining a route search extension distance of a train based on current location and speed of the train, wherein the current route search extension distance is the farthest distance in front of the train that is currently expected to be safe for operation based on current speed of the train; determining the currently required link and route resource contained thereof; determining the target authority of the route resource.

The invention is intended for conserving energy expended by railway rolling stock, for instance by a locomotive when carrying out train operations and shunting, when trains are run in an automatic mode or in a train operator assistance mode. A method for increasing the efficiency of rolling stock includes the following steps: obtaining the parameters of the rolling stock, including at least the following: speed, coordinates, overhead system voltage, traction engine current voltage, brake line discharging; in addition, determining at least the dependence parameters of an active traction force, braking force, motion resistance force, force of wheel adherence to the rails, and the mass of the rolling stock; then, determining the optimal control to be carried out by traction and braking equipment of railway rolling stock based on the dependence parameters obtained during the previous step; then, transmitting the optimal control, determined during the previous step, to a rolling stock control system for implementation or for displaying to the train operator.

A method includes generating a trip plan that dictates operational settings to be implemented by a vehicle system moving along a route. The trip plan is based on a temporary work order issued for a restricted segment of the route. The work order provides a maximum speed through the restricted segment for a limited time period that is expressed using a time standard. One or more of the operational settings of the trip plan specify movement of the vehicle system through the restricted segment at a vehicle speed that is less than or equal to the maximum speed. In response to determining that the temporary work order has expired, the method includes at least one of prompting an operator of the vehicle system to confirm that the work order has expired or generating a new trip plan in which the vehicle system exceeds the maximum speed through the restricted segment.

A method for controlling and recovering the adhesion, during a slipping phase, of wheels (W.sub.i) belonging to at least two controlled axles (A.sub.i) of a railway vehicle, comprising the steps of: generating speed signals indicative of the angular speed (?.sub.i) of said wheels (W.sub.i); estimating the value of the instantaneous adhesion (?(T.sub.j)) at the point of contact of such wheels (W.sub.i) and the rails, using an adhesion observer; generating a target-slip value (?) for the wheels (W.sub.i) of the controlled axles (A.sub.i) by means of an optimization algorithm which processes the estimated adhesion values (?.sub.i(T.sub.j)), and modifying the target-slip value continuously in time, with a predetermined sampling period, such as to maximize the average value of the adhesion of the wheels of the vehicle.

With such control system, rear-end train or more serious accidents may be avoided in case that there is a train without communication equipment or with equipment failure operation in front, or an obstruction impeding train operation appears in front of the train. Further, the control system provided by embodiments of the present disclosure enables a train to operate with a relatively high speed under the premise of safe operation, and improves operation efficiency and reliability.

A system includes an energy management system disposed onboard a vehicle system configured to travel on a route during a trip. The energy management system is configured to receive trip information that includes one or more constraints including at least one of speed, distance, or time restrictions for the vehicle system along the route. The energy management system is further configured to generate a trip plan for controlling movement of the vehicle system along the route during the trip. The trip plan is generated based on the one or more constraints. The trip plan has a plan speed profile that designates speeds for the vehicle system according to at least one of distance or time during the trip. The energy management system is further configured to control movement of the vehicle system during the trip according to the plan speed profile of the trip plan.

A system includes a locator device and one or more processors operably connected to the locator device. The locator device determines a trailing distance between a trailing vehicle system that travels along a route and a leading vehicle system that travels along the route ahead of the trailing vehicle system in a same direction of travel. The one or more processors compare the trailing distance to a first proximity distance relative to the leading vehicle system. In response to the trailing distance being less than the first proximity distance, the one or more processors set a permitted power output limit for the trailing vehicle system to be less than a maximum achievable power output for the trailing vehicle system, the permitted power output limit being set based on a power-to-weight ratio of the leading vehicle system.

A method and a system for transmitting enforceable instructions in a positive train control (PTC) system includes receiving, by a cyclic redundancy check (CRC) calculator, at least one enforceable instruction from railroad systems. The CRC calculator calculates at least one enforceable instruction CRC based at least partly on the at least one enforceable instruction and transmits the at least one enforceable instruction CRC to a back office server of the PTC system and/or an on-board system of a locomotive. Methods for cyclic redundancy check (CRC) hazard mitigation in a positive train control (PTC) system and verifying enforceable instruction data on-board a train are also disclosed.
