摘要:
A vehicle includes a body and at least one propulsion unit operatively coupled to the body. The vehicle also includes an electrical power system at least partially disposed within the body. The electrical power system includes a rechargeable battery and a health management unit operatively coupled to the rechargeable battery. The health management unit includes a state of health module configured to output information corresponding to battery health based on received battery-related data. The battery-related data includes data collected in real time operation of the rechargeable battery and battery relevant fault history of the vehicle.

A transponder module for vehicles. The module has a substantially universal vehicle sensor input interface capable of receiving sensor input from different types of vehicle sensors and from different types of vehicles. One or more processors and memory, in real time, receive vehicle sensor input data via the input interface. Based on a vehicle type stored in the memory, the processor(s) use the sensor input data to determine conditions of subsystems the vehicle. Based on the determined conditions, the processor(s) determine performance capabilities of the vehicle. The transponder module outputs information as to the stored vehicle type, determined conditions, and vehicle performance capabilities.

A system for identifying events includes a memory capable of storing a compressed event table including a number of events, the event table having been compressed by reducing the number of events in the event table without reducing the number of events represented by the event table. Each event of the event table includes a set of state parameters, and may also be associated with an output. The system also includes a processor capable of operating a fast state recognition (FSR) application. The FSR application, in turn, can receive a plurality of inputs, and identify an event of the compressed event table based upon the plurality of inputs and the state parameters of the compressed event table, event being identified in accordance with a state recognition technique.

A system and methods for mission re-planning are presented. Vehicles are monitored in real-time, and an incapacitated vehicle from among the vehicles that performs an incomplete task is detected. A remaining coverage set comprising a remaining coverage area for each of the vehicles is determined. A travel distance from a task completion location of each of the vehicles to a stopped point of the incapacitated vehicle is calculated to provide a travel set. An extra coverage set is determined based on the travel set and the remaining coverage set, and an incomplete coverage area for the incomplete task is calculated. The extra coverage set is compared to the incomplete coverage area and the remaining coverage area to provide a sufficiency list, and an assigned vehicle is selected from the vehicles based on the sufficiency list.

A system and method for dividing a predefined search region into a map of a plurality of subregions to be searched by a plurality of mobile platforms, taking into account the capabilities of the mobile platforms and varying environmental conditions within the subregions, while minimizing the time needed to search each of the subregions. The system and method updates the map of the subregions as needed, in real time, to account for changing environmental conditions and changes in the capabilities of the mobile platforms being used. The subregions may also be determined using a desired level of probability for detecting targets within the subregions in a desired number of passes through the subregion. The system optimizes coverage time while insuring a desired probability of coverage (i.e., observability) for heterogeneous mobile platforms.

A system and methods for life optimal power management of a distributed or centralized battery network system for use in aircraft functions and subsystems are disclosed. The method determines power priority of the subsystems, and selectively distributes power from the battery network system to the subsystems based on the power priority. Concurrently with distributing power, the method manages the energy in the battery network system. To determine whether the battery power is sufficient for aircraft functions, the method also computes and indicates the actual available energy left in the battery network systems. With this approach, the system and methods can provide a persistent power supply in the event an unexpected battery failure occurs, thereby enabling the aircraft to safely maintain flight operability despite a battery failure.
