Abstract: A method of testing a braking device in a drivetrain of a vehicle which includes at least one tractive element coupled to a traction motor. The method includes: (a) applying the braking device to a tractive element of the vehicle; (b) using an electronic controller, causing the traction motor to apply a predetermined force to the tractive element; and (c) using the controller, monitoring the tractive element for movement while the force is being applied. A dynamic braking or “retarder” function may also be tested. A system for carrying out the method is provided.

Abstract: A system includes a drive system having one or more traction motors coupled in driving relationship to a plurality of wheels of a vehicle system. The traction motors are configured to provide both motive power for the vehicle system in a propel mode of operation and retarding effort to brake the vehicle system in a braking mode of operation. The system further includes a parking brake for maintaining a static position of the vehicle system when in an engaged state, and a controller configured to detect when the parking brake is in the engaged state. The controller is further configured to control at least one of the one or more traction motors to provide a braking effort to resist movement of the vehicle system when the parking brake is in the engaged state.

Abstract: A method and system determine, during movement of a vehicle system along a route, a tractive load demanded by the vehicle system to propel the vehicle system along the route. The vehicle system includes a propulsion-generating vehicle having plural individually controllable traction motors. A first selected set of the traction motors for deactivation is identified during the movement of the vehicle system along the route based at least in part on the tractive load demanded by the vehicle system. The traction motors in the first selected set are deactivated while at least one of the traction motors in a first remaining set of the traction motors continues to generate tractive effort to propel the vehicle system. The traction motors that are selected for deactivation may all be on the same vehicle in the vehicle system, or may be on different vehicles of the same vehicle system.

CPC classification number: B61K5/04
Abstract: An apparatus for lifting and moving an axle of a rail vehicle includes a frame, a pair of rollers rotatably mounted to the frame to movably support the frame on a railroad track rail, and a pair of wedges mounted to the frame having mutually opposed ramped faces. The pair of wedges adjustable along the frame between a first position in which the ramped faces bracket, but do not contact, a rail vehicle wheel that rests on the track rail, and a second position in which the ramped faces engage the circumference of the wheel to support the wheel at a height above the railroad track rail. The apparatus further includes at least one jacking device for urging the wedges toward one another from the first position to the second position.

Abstract: A system includes a location determining circuit configured to acquire position information of a vehicle system moving along a route. The system also includes a controller circuit having one or more processors. The controller circuit is configured to calculate curvatures of the route, based at least in part on the position information, to form a curvature waveform. The controller circuit is further configured to generate a route map based on the curvature waveform.

Abstract: A system includes a sensor and a controller. The sensor is configured to detect sliding of a wheel of a vehicle. The controller is configured to communicate with the sensor and a traction motor operatively connected to the wheel such that the traction motor selectively applies forces in at least one direction to the wheel during operation. The controller is further configured to direct the traction motor to apply a motoring slide reducing force to the wheel when the sensor detects sliding of the wheel resulting from a frictional braking force.

Abstract: Methods and systems detect short circuits in an electrical system, such as a dynamic braking grid of a vehicle. The methods and system measure a characteristic of a current that is conducted through one or more resistive elements of an electrical system. The current is supplied to the electrical system from a power source as an applied voltage. A resistance change signal representative of a change in one or more electrical resistances of the one or more resistive elements is determined The resistance change signal can be based at least in part on a difference between the characteristic of the current that is measured and a low pass filtered value of one or more of the characteristic of the current that is measured or the applied voltage supplied by the power source. A short circuit event is identified based at least in part on the resistance change signal.

Abstract: A method and system for determining rail defects. The method and system receive route performance measurements from a vehicle system traveling along a route and normalize the route performance measurements based on one or more characteristics of the vehicle system. The method and a system also determine a defect for a segment of the route based at least in part on the normalized route performance measurements with respect to a threshold bandwidth corresponding to the segment. The method and system also examine velocity differences in a vehicle speed of a vehicle and the angular speed of the axles and/or wheels of the vehicle system traveling along a route to determine if the route is damaged and/or to identify the location of the potentially damaged section of the route. The differences may represent wheel creeps of the vehicle system.

Abstract: A control system including a measurement module configured to receive motor measurements that represent operating parameters of plural traction motors of a common vehicle system as the vehicle system propels along a route. The control system also includes an analysis module configured to compare the motor measurements to an expected measurement. The expected measurement corresponds to a designated motor type. The analysis module is configured to determine that at least one of the traction motors is different from the designated motor type based on comparing the motor measurements to the expected measurement.
