A system and method for controlling a vehicle system may determine one or more of a route parameter of a route on which the vehicle system is moving or a vehicle parameter of the vehicle system. The system and method may also determine whether a ratio of a lateral force exerted by one or more wheels of the vehicle system on the route to a vertical force exerted by the one or more wheels of the vehicle system on the route increases to a value exceeding a designated threshold as a result of the one or more route parameter of vehicle parameter that is determined. The ratio of the lateral force to the vertical force exerted by the one or more wheels of the vehicle system on the route may be reduced to a value less than the designated threshold by changing an operation of the vehicle system.

Vehicle control system

A system includes one or more sensors that generate sensor measurements representing a first parameter of one or more components of a power circuit. The system includes a control unit that obtains a reference rate of change value of the first parameter based at least in part on the sensor measurements over time. The control unit compares rates of change of monitored values of the sensor measurements over time to the reference rate of change value over time, and determines a deviation condition in response to the rate of change of a first monitored value of the sensor measurements differing from the reference rate of change value by more than a determined tolerance margin value. The control unit generates a control signal responsive to detecting the deviation condition to change an operating condition of at least one of the components of the power circuit.

Deviation detection system for power circuit

A system and method determine (a) thermal characteristics of an energy storage apparatus that supplies electric current to one or more vehicular loads for powering the one or more vehicular loads and/or (b) electrical characteristics of the energy storage apparatus or the one or more vehicular loads. The system and method determine whether operation of the energy storage apparatus indicates that the energy storage apparatus is unexpectedly heating or unexpectedly cooling and identifying a fault in the energy storage apparatus responsive to determining that the energy storage apparatus is unexpectedly heating or unexpectedly cooling.

Monitoring system for an energy storage apparatus

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.

Vehicle control system and method

A ground impedance and fault detection system may include a controller that can identify a location of a ground fault in a circuit. The circuit also may include one or more positive contactors connected with a positive portion of the bus between battery strings and a load and a negative bus contactor coupled with a negative portion of the bus between the battery strings and the loads. The controller may identify the ground fault by opening the one or more positive contactors and closing the negative bus contactor, measuring the voltages using the impedance devices, and comparing the voltages that are measured.

Ground impedance and fault detection system and method

A system and method includes commencing movement of a vehicle system including a plurality of vehicles from a stationary state. Operation of the vehicle system is controlled to control spacing between the vehicles of the vehicle system.

Systems and methods for operating a vehicle system

A method and system controller includes determining a power requirement for a vehicle system to complete a planned trip over a route. The method includes determining whether an amount of available power from the vehicle system is sufficient to propel the vehicle system to complete the planned trip by comparing the available power with the power requirement that is determined. The method includes changing one or more operational aspects of the planned trip based on the comparison between the amount of available power and the power requirement that is determined to generate a newly planned modified trip.

An assembly is provided that may include a battery, and an end cap mechanically and electrically coupled to the battery. The end cap may contain an electrical connector with at least one electric cable configured to supply current to at least one operating system electrically coupled to the battery. The end cap may also contain at least one electronic board coupled to the battery, and may be configured to detach from the battery to provide access to the electrical connector and the electronic board.

Assembly and method for battery maintenance

A vehicle control system and method include processors that determine that an energy storage device of a vehicle will have insufficient energy to power a propulsion system of the vehicle under a first set of operational settings to move the vehicle from a first location within a powered segment to a designated second location that is outside of an unpowered segment of a route. Responsive to determining that the energy storage device will have insufficient energy, the processors change one or more settings of the vehicle to operate the vehicle under a second set of operational settings while the vehicle moves within the powered segment of the route to charge the energy storage device to a greater extent relative to operating of the vehicle according to the first set of operational settings.

An electric supply system for a vehicle system includes two or more electric energy storage devices. Two or more buses each conductively couple an energy storage device with a corresponding load of plural loads. A controller controls conduction of current from one or more of the energy storage devices to one or more other buses to transfer energy to other energy storage devices or other loads. A method includes directing a first energy storage device of a first power supply assembly to supply electric current to a first bus conductively coupling the first energy storage device to one or more first loads onboard the vehicle system. The method further includes conducting the electric current from the first energy storage device to one or more second buses of one or more second power supply assemblies to recharge one or more second energy storage devices or power one or more second loads.

The one or more processors may communicate a message associated with the wheel size to an off-board device when the wheel size is below a threshold size.

System and method for controlling an axle of a vehicle

A charge transfer timing system and method include determining a charge capability of one or more power sources configured to supply charging power to multiple battery packs of a powered system. The system and method include calculating a time required to charge the battery packs to at least one of a target voltage or a target energy level. The time that is calculated may be based at least in part on a current state of charge (SOC) of the battery packs, a pack configuration of the battery packs, and the charge capability.

Charge transfer timing system and method

A method includes detecting an out of phase condition and an in-phase condition between a vehicle platform and two or more propulsion units attached to the platform. A first speed from a first propulsion unit is compared to a second speed and a torque of one or more propulsion units is controlled to reduce the out of phase condition and/or the in-phase condition when a difference between the first speed and the second speed is greater than a threshold value. A vehicle includes a platform, two or more propulsion units attached to the platform, and a processor. The processor compares a first speed from a first propulsion unit to a second speed, detects from the comparison an out of phase condition between the platform and the two or more propulsion units, and detects from the comparison an in-phase condition between the platform and the two or more propulsion units.
