摘要： Systems and methods for controlling operation of a vehicle system are provided. This vehicle system can be at least partially powered by electric current conducted to a collector device of the vehicle system from a conductive pathway extending along a route traveled by the vehicle system. A voltage level of the conductive pathway may be monitored, and a conduction impaired location of the conductive pathway may be identified based at least in part on the voltage level of the conductive pathway that is monitored. The collector device or a removal device may be controlled to remove a contaminant from the conductive pathway at the conduction impaired location, the vehicle system may be controlled to compensate for the conduction impaired location, and/or an off-board facility and/or another vehicle system may be notified of the conduction impaired location responsive to identifying the conduction impaired location.

摘要： A method including detecting that a vehicle that may be propelled by an electric drive system having one or more motors disconnects or begins disconnecting from an off-board source of power while the one or more motors are being powered by the off-board source of power. The method may include supplanting a decreasing amount of a first electric energy supplied by the off-board source of power to the electric drive system with an amount of a second electric energy supplied by an onboard source of power to the electric drive system responsive to the detection of the disconnect from the off-board source of power.

摘要： Systems and methods for reducing slack in a linkage chain of a vehicle truck assembly is provided. In one example, a method includes compressing a vehicle suspension by actuating an actuator with a cylinder abutted to a piston rod, the piston rod coupled to the vehicle suspension and, when deactivating the actuator, maintaining at least nominal compression on the vehicle suspension with the piston rod spaced away from a piston of the cylinder via a biasing member, the piston configured to slide within the cylinder along a central axis of the cylinder.

摘要： A method for reducing slack in a linkage chain of a vehicle truck assembly is provided. In one example, the method includes responding to a request to de-lift a lift mechanism by reducing pressure in an actuator coupled to the lift mechanism, where the lift mechanism is configured to transfer a load from a first axle to a second axle of the vehicle during the de-lift, and during the de-lift, maintaining the pressure in the actuator at or above a threshold pressure to maintain tension in a weight transfer device of the lift mechanism.
