  • Patent number: 10899350
    Abstract: A method and system include a vehicle system including a plurality of vehicles. The system includes a handling unit comprising a communication device and a controller. The communication device receives first position data for a first vehicle of the vehicle system and second position data for a second vehicle of the vehicle system relative to a route on which the vehicle system is traveling. The controller determines that the first vehicle is entering into a curved portion of the route, and generates a control signal based on the first and second position data. The control signal changes an operating parameter of at least one of the first or second vehicles to control a separation distance between the vehicles or a deviation distance between respective travel paths taken by the first and second vehicles through the curved portion of the route.

  • Patent number: 10845426
    Abstract: A system for testing a ground fault detection system in an electric circuit establishes a ground connection between a bus and the ground via an inverter and a load by closing an inverter switch of the inverter and a grounding switch disposed between the load and the ground, determines whether the ground connection is detected, and determines a fault in the ground fault detection system responsive to the first ground connection not being detected by the ground fault detection system. Optionally, a ground fault may be identified by determining three phase voltages provided from each of plural inverters, determining symmetrical components of the three phase voltages for each of the inverters, and identifying a ground fault in one or more of the inverters while powered by the power supply based on the symmetrical components.

  • Patent number: 10829104
    Abstract: A vehicle control system examines characteristics of an upcoming segment of a trip of a hybrid vehicle. One or more locations in the upcoming segment of the trip are identified based on the characteristics as places where an engine of the vehicle is incapable of generating enough energy to power the vehicle through the locations. Operational settings of the vehicle are calculated based on the locations to operate the vehicle in a way that charges an energy storage device with energy that can be used to replace or supplement the energy provided by the engine to propel the hybrid vehicle over or through the locations. The one or more processors are configured to one or more of automatically control or generate a control signal for automated operation of the hybrid vehicle according to the one or more operational settings that are calculated.

  • Patent number: 10780772
    Abstract: A locomotive propulsion system includes an engine assisting apparatus and an engine control unit that monitors an output parameter of a locomotive engine. The control unit determines whether the engine output decreases sufficiently low to at least partially de-fuel the engine and to activate an assisting apparatus.
