TRAIN EMISSION CONTROL SYSTEM
A system that can automatically control the emissions of each locomotive in a consist to reduce overall train emissions. An emissions module determines the amount of emissions emitted by a train. An emissions control module commands the locomotive, via the train control system, to operate in a predetermined state to achieve a particular amount of emissions. A location module can track the location of the locomotive of the train relative geographic locations having emission regulations so that the emissions control module can command appropriate changes in the locomotive to reduce emissions.
METHOD FOR SAFELY OPERATING A RAIL TRAFFIC SYSTEM AND RAIL TRAFFIC SYSTEM
A method for safely operating a rail traffic system, comprising the steps: comprising first rail traffic information correlating with a state variable of the rail traffic system, transmitting second rail traffic information correlating with the state variable of the rail traffic system between a first rail vehicle and an infrastructure facility and/or a second rail vehicle, determining a comparison result using the first rail traffic information and the second rail traffic information, checking the plausibility of the first rail traffic information and/or the second rail traffic information using the comparison result, and controlling the rail traffic system using the result of the plausibility check.

Train control method for maximizing utilization of regenerative energy
Embodiments of the present invention provide a train control method for maximizing utilization of regenerative energy. The method mainly comprises: working out a matching error T of a current matched pair of trains Mx (i, j) of a station in the current running situation; and comparing the matching error T with a preset maximum adjustable error T.sub.x of the current matched pair of trains Mx (i, j) of the station and determining a strategy for adjusting train running of the current matched pair of trains Mx (i, j) according to comparison results.
SPEED CONTROL SYSTEM FOR A RAILCAR MOVER
A speed control system for a railcar mover where the speed control system prevents the railcar mover from exceeding a predetermined maximum vehicle speed. The speed control system determines a target engine speed that overrides a user's throttle control input to keep the railcar mover from exceeding the predetermined maximum vehicle speed. The speed control system also determines a target throttle control position and disables the throttle control from the user until the user moves the throttle control to a position at or less than the target throttle control position.
BRAKING FORCE DISTRIBUTION METHOD AND SYSTEM OF MULTIPLE TRAIN UNITS
A braking force distribution method and system for multiple marshalling train compartments are provided. The method includes: determining a current train compartment of multiple target marshalling train compartments, calculating current axel loads of axels of the current train compartment, and distributing braking forces for the axels of the current train compartment in a positive correlation manner based on the current axel loads of the axels. The braking forces of the axels are distributed by using an axel load compensation technology. A braking force generated by an axle with a small axle load is reduced according to a load-decreasing amount of the axle load, while a braking force generated by an axle with a great axle load is increased according to a load-increasing amount of the axle load, so that the braking forces generated by the axles match the axle loads.
METHOD, SYSTEM AND APPARATUS FOR SELF-DRIVING VEHICLE OBSTACLE AVOIDANCE
Systems and methods for obstacle avoidance with a self-driving vehicle are provided. The system comprises a processor connected to the self-driving vehicle and a sensor in communication with the processor. The sensor is configured to detect objects. The processor is configured to receive a measurement of the self-driving vehicle's speed, and define a sensor region based on the speed. The processor can determine that an object detected by the sensor is within the sensor region, and then initiate a fail-safe routine. The sensor region may be defined based on a range parameter. The sensor region may be defined based on the stopping distance of the vehicle. The sensor region may be redefined when the vehicle's speed changes.
VEHICLE CONTROL SYSTEM
A control system includes a communication device onboard a vehicle system approaching or entering an airflow restricted area along a route and one or more processors.
