A system and method are provided for battery control of hybrid vehicles such as, but not limited to, hybrid locomotives. The system and method are implemented to sense a present state of charge (SoC) of one or more batteries and generate present SoC data there from, sense a present excursion defined by a relationship represented as maximum SoC&#x2212;minimum SoC for a desired cycle and generate present excursion data there from, and control the one or more battery power/current charging limits in response to the present SoC data and the present excursion data.

System and method for battery control

A system is provided for segregating an energy storage system from at least one of at least one air pipe and at least one electric cable of a hybrid energy vehicle. The energy storage system includes at least one energy storage device and at least one hybrid cable. The system includes a pair of first regions proximately positioned below a respective pair of walkways extending along opposing sides of the vehicle, and a second region positioned between the pair of first regions. The energy storage system and at least one of the at least one air pipe and at least one electric cable are respectively positioned within one of the pair of first regions and the second region to segregate the energy storage system from at least one of the at least one air pipe and at least one electric cable of the hybrid energy vehicle.

A compressed air system and method of operating the system wherein the slip between the compressor motor and its powering alternator is used as an indication of whether the compressor is running in a loaded or unloaded mode. A slip parameter such as % Slip is determined and compared to an allowable value in real time. If the compressor is determined to be erroneously in a loaded mode, a corrective action may be taken to reduce the probability that the motor is later started with the compressor still in the loaded mode.

The invention includes a system and method for managing an operation of a locomotive as a function of a location of the locomotive. The system comprises a location unit for determining the location of the locomotive and a control unit for controlling an operation of the locomotive as a function of the determined location. In another embodiment, the invention includes a system and method for receiving a security authorization input from an operator of the locomotive, comparing the received operator security authorization input to a security authorization parameter, and restricting an operation of the locomotive when the received operator security authorization input does not match the security authorization parameter. In yet another embodiment, the invention includes a system and method of sending a control command from a remote system, receiving the control command at the locomotive, and controlling an operation of the locomotive responsive to the received control command. In still another embodiment, the invention includes a system and method for controlling an operation of the locomotive as a function of the location of the locomotive, a monitored emission parameter and an emission characteristic.

Locomotive control system and method

A compressed air system, wherein a decision to de-energize a compressor motor is made with consideration of the likely need for the operation of the compressor at a future point in time. A rate of pressure decay in an air reservoir may be extrapolated over a predetermined time period to predict the need for operation of the compressor within the time period. If operation of the compressor is predicted to be needed within the time period, the compressor is allowed to continue to run in an unloaded mode beyond a normal cool down period.

Compressed air system and method of control

A method and apparatus for chronologically combining fault data, repair data, and operational parameters for a railroad locomotive. Generally, this data is collected and stored in separate databases. The present invention teaches combining the data so that an ordered analysis reflecting the timing of faults, repairs, and operational information can be carried out to determine the root causes of the faults.

Diagnosis of faults in a complex system

An apparatus for determining the direction of locomotive travel while in dynamic braking is disclosed. This direction of travel is derived from current sensors associated with the locomotive traction motors. When in the dynamic braking mode, current flows through the current sensors in a first direction when a train is traveling in the first direction and reverses the direction of flow when the train is traveling in a second direction.
