摘要： A system is provided that includes a controller having one or more processors. The one or more processors may be configured to obtain first vehicle system data from a first vehicle system of plural vehicle systems based on a common characteristic shared by the plural vehicle systems, and obtain second vehicle system data from a second vehicle system of the plural vehicle systems, the second vehicle system data based on the common characteristic shared by the two or more vehicle systems. The one or more processors may also be configured to compare the first vehicle system data to the second vehicle system data, and identify one of the first vehicle system or the second vehicle system as a candidate vehicle system for maintenance based on comparing the first vehicle system data to the second vehicle system data.

摘要： A system and method that identify a location and/or magnitude of a ground fault in a circuit having a bus that connects battery strings with loads and a ground reference between the loads are provided. Potential of the bus is shifted relative to a ground reference in a first direction. A first impedance in the bus between the battery strings and the ground reference is determined, and the bus is shifted relative to the ground reference in a second direction. A second impedance in the bus between the battery strings and the ground reference is determined. A location and/or severity of a ground fault is determined based on a relationship between the first impedance and the second impedance.

摘要： A controller of a first vehicle system that moves along a first route and a method related thereto includes determining a first prioritization score of the first vehicle system moving along the first route. The first prioritization score indicates one or more characteristics of the first vehicle system. A second prioritization score of a second vehicle system moving along the first route or a second route that intersects the first route is received. The second prioritization score indicates one or more characteristics of the second vehicle system. A prioritization ranking is determined between the first vehicle system and the second vehicle system by comparing the first prioritization score of the first vehicle system with the second prioritization score of the second vehicle system. Movement of the first vehicle system is automatically controlled based on the prioritization ranking.

摘要： A control system including one or more processors that may determine vehicle locations of one or more vehicles and states of charge of vehicle energy storage devices onboard the one or more vehicles. The control system may include an energy chassis having a fuel source holding a supply of fuel, an energy converter to convert at least a portion of the supply of the fuel from the fuel source into electric energy, and a communication device to communicate with the processors. The processors may direct which of the one or more vehicles are to couple with and be powered by the electric energy of the energy chassis based on one or more of: the vehicle locations, the states of charge of the vehicle energy storage devices, an amount of the supply of the fuel of the energy chassis, and a chassis location of the energy chassis.

摘要： Various methods and systems are provided for a method for a multi-pressure fueling system. In one example, the multi-pressure fueling system includes providing a first fuel delivery pressure enabling high pressure direct injection of a fuel at a first injector and a second fuel delivery pressure insufficient for high pressure direct injection, at a second injector, based on engine operation.

摘要： Methods and systems are proposed for controlling a temperature of exhaust gases generated by the engine by operating an E-Turbo of the vehicle. In one embodiment, a method is provided, comprising increasing a power generated by an electric machine mechanically coupled with an exhaust turbine of an E-Turbo of a vehicle or adjusting an engine power based on a speed of the exhaust turbine and an air-fuel ratio (AFR) of an engine of the vehicle of the engine responsive to the speed of the exhaust turbine increasing above a threshold turbine speed. By increasing or decreasing the power generated by the electric machine and/or adjusting the engine power, the temperature of the exhaust gas may be maintained within a threshold temperature range where an efficiency of an aftertreatment system may be maximized, thereby reducing an emissions of the vehicle.

摘要： A system includes one or more processors that are configured to obtain a constraint on movement for a first vehicle system along a route. The constraint is based on movement of a separate second vehicle system that is concurrently traveling along the same route. The processor(s) are configured to determine a speed profile that designates speeds for the first vehicle system according to at least one of distance, location, or time based on the constraint such that the first vehicle system maintains a designated spacing from the second vehicle system along the route.

摘要： A vehicle control system an onboard controller device to interface with a propulsion system and a brake system. A remote controller device wirelessly communicates with the onboard controller device and receives input from an operator, generates control signals based on the input, wirelessly communicates the control signals to the onboard controller device while the vehicle system moves along one or more main line routes. A method includes receiving input from an operator at a remote controller device, generating control signals at the remote controller device based on the input from the operator, wirelessly communicating the control signals to an onboard controller device, controlling one or more of a propulsion system or a brake system of the vehicle system to change movement of the vehicle system while the vehicle system moves along one or more main line routes.

摘要： A system and method generate a trip plan for a trip of a vehicle system along a route. The usage of an engine during the trip is determined based on engine operational parameters, energy storage device operational parameters, and one or more objectives of the trip desired to be achieved. The usage of the energy storage device during the trip is also determined based on the engine operational parameters, the energy storage device operational parameters, and the one or more objective, including when to charge or discharge the energy storage device during the trip.

摘要： A system is provided that may include plural data collector devices that may be configured to be communicatively coupled with each other in a network. Each of the data collector device may include one or more processors configured to receive display data from one or more data sources. The one or more processors may also be configured to communicate different portions of the display data to different respective network locations in the network. The one or more processors of each of the data collector devices may also be configured to control a respective display device of several display devices to alternate between displaying the different network locations at different times.
