Abstract:

Methods and systems are provided for operating an engine, the engine coupled to a traction alternator for vehicle travelling. In one example, the method includes, in an off-highway vehicle running mode of operation, supplying current from the traction alternator to a traction motor via a traction inverter to propel the vehicle, and, in a starting mode of operation, supplying stored energy from a first energy source and a secondary energy source to the traction alternator to start the engine.

US Classification:

219202, 392379

Abstract:

A system is provided for use with a rail vehicle having a wheel that travels on a rail. The system includes an air source for supplying compressed air and a heating unit fluidly coupled to the air source and configured to produce heated compressed air by heating the compressed air or heating air prior to the air being compressed by the air source, and to direct the heated compressed air onto a contact surface of the rail.

International Classification:

H03K 5/08

US Classification:

327326

Abstract:

A power unit (e.g., inverter module) includes a housing and a switch attached to the housing. The switch may be configured to be electrically coupled to a remotely-mounted drive circuit through two or more wire leads. The power unit also includes a clamping circuit electrically coupled to terminals of the switch and in parallel with the switch. The clamping circuit may be disposed inside the housing or on an outer surface of the housing, and is configured to limit a voltage across the switch.

International Classification:

B60M 3/02
B60M 1/30
B60M 7/00
B60L 9/12

Abstract:

A method and system include determining a resonant frequency of a vehicle system operably coupled with an external power source that provides voltage and current to the vehicle system. A first filter extracts a phase or a frequency component from the voltage provided by the external power source to generate a stabilizing voltage component. A second filter extracts a phase or a frequency component from the current provided by the external power source to generate a stabilizing current component. The stabilizing voltage component is out of phase with the stabilizing current component. A control input of a converter device of the vehicle system is determined based on the stabilizing voltage component, the stabilizing current component, and the resonant frequency. The stabilizing voltage component, the stabilizing current component, and the control input are communicated with the converter device to change the resonant frequency of the vehicle system.

Abstract:

A monitoring system and method determine a consumption metric representative of one or more of an amount of fuel consumed or an amount of energy consumed by a vehicle during travel over a route. The consumption metric is independent of one or more of vehicle load or elevation change over the route. The system and method optionally can determine a route condition metric representative of a condition of a route traveled upon by a vehicle. The route condition metric is based on a comparison between an actual grade of the route at one or more locations along the route and an estimated grade of the route at the one or more locations.

International Classification:

B60L 7/02
H01C 3/10
H01C 1/082

Abstract:

A resistive grid includes a frame and at least one resistive element. The frame has a first frame end and a second frame end opposite the first frame end. The first frame end and the second frame end are joined by frame sides. The first frame end has a first length that is shorter than a second length of the second frame end. The at least one resistive element extends between the first frame end and the second frame end. The at least one resistive element has a first portion proximate the first frame end, and a second portion proximate the second frame end. The first portion is configured to have one or both of decreased heat generation or decreased electrical resistance relative to the second portion.

International Classification:

B60R 16/03
H02M 5/458

Abstract:

A power supply system includes an onboard rectifier that may be disposed onboard an electric vehicle. The onboard rectifier is configured to receive an alternating current conducted from a power generating station via a transmission line at a frequency that is at least a utility power line frequency. The onboard rectifier may change the alternating current into a direct current and to output the direct current to an electric propulsion system of the electric vehicle to power the propulsion system and propel the electric vehicle.

Jeffrey John Wolff - Erie PA, US

International Classification:

B60K 1/04

Abstract:

A mounting system includes a chassis, guide rods, and lifting elements. The guide rods extend from a back wall of the chassis and are suspended above a support platform of the chassis. A first guide rod is spaced a designated height above the support platform to be received within a channel of a module while the module is disposed on the support platform. The first guide rod guides movement of the module towards the back wall. As the module approaches the back wall, a first lifting element engages the module at an angled contact interface to lift the module off the support platform responsive to additional movement of the module towards the back wall. When the module is fully loaded, the module is supported by the back wall, the first lifting element, and/or the first guide rod, and is spaced apart from the support platform by a gap.
