2. Description of the Related Art
Logistical or supply chain structures involve the acquisition, storage, transport, and supply of commodities and raw materials within an organization. For simple and/or relatively small organizations, supply chain management is complex and frequently requires the use of one or more systems dedicated to supply chain logistics to ensure the smooth operation of the organization. For larger and/or more complex organizations such as large commercial entities, governmental agencies, and military organizations, supply chain logistics represent an important part of not only keeping the organization functioning, but also of improving the speed, efficiency, cost control, and responsiveness of the organization.
For many organizations, the supply chain structure includes the necessary staffing and infrastructure to ensure equipment (e.g., uniforms, forklifts, trucks, aircraft), consumables (e.g., food, fuel, parts), and a service organization (e.g., manuals, training, policies, procedures) to repair and maintain the equipment is available in the necessary volume and in the appropriate locations. For a commercial organization, streamlined and efficient supply chain logistics can assist in providing customers and clients products and services at the lowest cost. For a military organization, streamlined and efficient supply chain logistics can advantageously increase the responsiveness and ability of the organization to respond quickly and efficiently on either a short or long term basis in remote regions of the world.
More complex assets such as trucks, all-terrain vehicles, specialized equipment, and the like require significant maintenance to ensure a high level of equipment availability and maximize reliability. For large, diverse organizations such as military organizations, standardized documents, training, and procedures reviewed and approved for distribution by an administrative agency and authorized for use throughout all or a portion of the organization ensure the use of similar or common practices and procedures by all personnel. Such maintenance and service procedures improve the responsiveness of the organization since equipment, crew, and support personnel are individually assignable.
Within many organizations, training and documentation change frequently to reflect changing conditions and circumstances as well as to reflect previously unforeseeable events and conditions. Prior to “rolling out” such changes, many fleet operators impose a formal review and approval processes. Thus, in addition to supply chain logistical issues, many organizations, particularly governmental and military organizations impose a relatively complex, formal, approval structure on the distribution of documentation related to the maintenance and repair of vehicles and equipment. When combined with routine or typical changes that occur in vehicles and equipment throughout a production run, many organizations would benefit from an integrated management system able to track supply chain logistics, document preparation and approval, and document distribution to appropriate operating and maintenance personnel.
To reduce the volume of documentation required to support the field repair and maintenance of vehicles such as military vehicles portable electronic devices such as tablet computers can replace and/or augment more traditional, printed, service, maintenance and repair documentation. The use of portable electronic devices offers several advantages including a significant reduction in the weight and volume of documentation needed to field repair and maintain vehicles and equipment. Additionally, electronic documentation supports the presentation of maintenance and repair information in machine executable formats such as animations, audio, video, and audio/visual presentations heretofore impossible to include in printed documentation. Finally, the use of portable electronic devices permits the near instantaneous bi-directional transmission of information from the field to a back-end system and from the back-end system to the field, when a communications channel is available and the vehicle is not operating in a radio silence mode. Such information can include the transmission of data indicative of vehicle system and/or vehicle condition by a field portable device to a back-end system. Such information may also include the transmission of analytical data, parts and/or materials availability, and location information from the back-end system to the field portable device. Such information may additionally include the transmission of up-to-date checklists and/or instruction sets relevant to the vehicles associated with a particular portable device from the back-end system to the respective portable device.
Each portable device assigned to a vehicle crewmember or field maintenance technician is logically associated with a number of vehicles that may be of the same make and model or may be of different makes and/or models. Each vehicle carries vehicle identification information that uniquely identifies the vehicle. Responsive to receiving data indicative of a vehicle identifier, the portable device can cause one or more checklists and/or instruction sets to appear on a display device. The portable device receives vehicle system data either autonomously via a tethered (e.g., wire, optical fiber) or wireless (e.g., RF, microwave, radio, transmitter, receiver, transceiver) connection to the respective vehicle or manually via input provided by the vehicle crewmember or maintenance technician assigned to the respective vehicle.
Vehicle system and/or condition data received by the portable device is stored at least temporarily within a nontransitory memory or non-volatile storage device. The portable device transmits vehicle system and/or condition data to a remote recipient such as a back end system where the data can be analyzed, actual or potential maintenance or repair issues identified, and parts and materials needed for maintenance and repair of the vehicle dispatched to a defined location. Additionally, where maintenance and repair instructions are not stored locally on the portable device, the back-end system can communicate the maintenance and repair instructions to the portable device.
Vehicle related authored assets include the aforementioned checklists and/or instruction sets as well as other maintenance, repair and operational information provided by vehicle manufacturers and/or equipment suppliers. Vehicle manufacturers and/or equipment suppliers supply such vehicle related authored assets in electronic format or in a physical format that is convertible to an electronic format, for example through scanning and/or optical character recognition. Within the vehicle fleet operator's organization, formal review and approval processes occur prior to distributing the vehicle related authored assets to crewmembers and/or field maintenance technicians.
The back-end system can include an Authoring Versioning Approval System that tracks the formal review and approval of the vehicle related authored assets by the fleet operator's organization. An Authored Content Distribution System then distributes the approved vehicle related authored assets to the portable devices associated with vehicle crewmembers and field maintenance technicians assigned to a particular vehicle. An Auditing System monitors the checklists and/or instruction sets on each of the portable devices to ensure the most recent versions relevant to the vehicles associated with each portable device are loaded on the respective portable device. The back-end system also includes a Vehicle Deployment Positioning System to locate and dispatch replacement equipment and/or vehicles to defined locations to replace vehicles as determined by the back-end system.

The headings and Abstract of the Disclosure provided herein are for convenience only and do not interpret the scope or meaning of the embodiments.
One or more digital processors or controllers 104 control some or all of the mechanical or electrical systems found in many private, commercial, and military vehicles 102. For example, vehicle engines often have one or more controllers 104 to adjust motor operating parameters to improve fuel efficiency, reduce emissions, or alternate between powertrain systems (e.g., switch between internal combustion and hybrid powertrain systems). Vehicle powertrains may have a number of controllers 104 to implement antilock braking, operate traction control, switch between drivetrain systems (e.g., switch between two wheel and four wheel drive systems). Instrumentation, climate control, and communications systems may share of have dedicated controllers 104. In operation, each controller 104 receives signals from sensors and similar data acquisition or data collection devices or systems coupled to one or more vehicular systems. Based on the received data, each controller 104 is able to operate, control, alter or adjust one or more vehicular system operating parameters as well as determine when one or more systems may be in need of maintenance or repair. For example, a “CHECK ENGINE” light (or similar indicator) may indicate the need for service or repair to the vehicle engine or one or more engine support systems (e.g., fuel, air, emissions control, ignition) to the vehicle operator. At times, a diagnostic or service code generated by one or more controllers 104 may accompany such an indicator. These diagnostic or service codes provide vehicle crewmembers or maintenance personnel with an indication of the type of service, repair, and/or maintenance procedure required to restore the vehicle to a desired operating condition. On the other hand, military and commercial vehicles may be equipped with one or more busses (e.g., a controller area network or “CAN” bus) to facilitate the communication of such maintenance, repair or diagnostic signals between onboard controllers or between the controllers and one or more remote devices. The ability to transmit service information from each vehicle advantageously permits the coordination of maintenance via one or more centralized systems.
In at least some instances, each vehicle 102 may be equipped with one or more communications interfaces 106a-106n (collectively “communications interfaces 106”) to facilitate communication between the vehicle 102 and one or more external devices 110. For example, the communications interface 106 may communicably couple a vehicle to an external device 110 via a tethered connection 108a, a wireless connection 108b, or some combination thereof (collectively “connection 108”). Such data may include, without limitation, data provided autonomously by a vehicular controller, data provided by autonomously by a vehicular sensor, data provided manually by a vehicle operator or crewmember, or any combination thereof. In at least some instances, the communications interface 106 may be communicably coupled to at least one or more vehicular busses (e.g., the CAN bus). In some instances, (not shown in
The portable device 110 can include any device capable of communicably coupling to one or more vehicles 102 via one or more connections 108. Example external devices can include, but are not limited to: portable computing devices such as tablet and laptop computers; handheld computing devices such as personal digital assistants and smartphones; and wearable computing devices such as Google® Glass® which may provide authored content in a form of virtual or augmented reality presentations.
In at least some instances, the portable device 110 may include a vehicle operation tablet computer. The vehicle operation tablet computer may be assigned to a vehicle crewmember staffing the vehicle or to a dedicated vehicle maintenance technician. In some instances, the vehicle operation tablet computer provides checklists and/or instruction sets 112 to the system user based at least in part on the primary role assigned to or associated with the system user. For example, the vehicle checklists and/or instruction sets 112 provided by the vehicle operation tablet computer to an identified maintenance technician may have greater technical content or technical scope than the vehicle checklists and/or instruction sets 112 provided to an unidentified user or a user identified by the vehicle operation tablet computer as a vehicle crewmember having a different primary assignment. In another example, the vehicle checklists and/or instruction sets 112 provided to a maintenance technician qualified at a higher level of technical training or education (e.g., a certified level 4 vehicle maintenance specialist) may contain instructions or procedures not included in the vehicle checklists and/or instruction sets 112 provided to an unqualified maintenance technician or a maintenance technician qualified at a lower level of technical training or education (e.g., a certified level 1 mechanic).
The vehicle operation tablet computer assigned to a group or unit operating a limited number of different vehicle makes and/or models may contain stored, saved, or otherwise retained checklists and/or instruction sets 112 relevant to only those vehicle makes and models associated with or assigned to the unit. Thus, a logical association may exist between the vehicle operation tablet computer and a limited number of vehicle makes and models. For example, a vehicle operation tablet computer assigned to a unit equipped principally with wheeled vehicles may not include checklists and/or instruction sets 112 associated with the maintenance and repair of tracked vehicles.
Data communicated by the vehicle 102 to the external device 110 is communicated in whole or in part with one or more back-end systems communicably coupled to the external device 110 via the network 114. Such back-end systems may include, but are not limited to: one or more inventory logistics systems 120, one or more diagnostics systems 130, one or more vehicle deployment or positioning systems 140, one or more authored content versioning approval systems 150, one or more authored content distribution systems 160, and/or one or more auditing systems 170. Each of these systems is described in detail below.
The inventory logistics system 120 can provide supply chain management for the parts and materials used to repair and maintain the vehicles 102. Maximizing the operational availability of vehicles 102 typically entails delivery of parts and materials used in the operation and maintenance of vehicles 102 to appropriate locations and at appropriate times when each particular vehicle is available for maintenance and repair. The inventory logistics system 120 coordinates the flow of parts and materials from the supplier to one or more warehouse, depot, or distribution points for storage and forwarding to one or more field, repair, and/or maintenance locations. The inventory logistics system 120 further coordinates the delivery of parts and materials used in maintaining and repairing particular vehicles in a field location or service depot location where a particular vehicle is positioned and at a time when the particular vehicle is available for maintenance or repair. The inventory and logistics system 120 can further coordinate the expedited delivery of parts and materials used in the repair of vehicles suffering damage in the field. In at least some instances, the inventory logistics system 120 may be included in an enterprise management system that includes at least accounting functionality (e.g., order placement, order tracking, accounts receivable/payable functionality). In at least some instances, the inventory logistics system 120 may be included in a transportation management system that includes sea, air, and land routing and/or logistics for distribution and delivery of parts and materials used in the maintenance and repair of vehicles 102.
In at least some instances, the inventory logistics system 120 may include one or more modules or subsystems that predict the type and number of parts and/or materials used at a particular location or to maintain or repair a particular vehicle type based at least in part on the operating environment in which the vehicle is deployed. Such modules or subsystems advantageously facilitate the use of “just in time” or similar delivery schemes that minimize parts and/or maintenance item inventory carrying costs at warehouse, depot, or distribution locations.
The diagnostics system 130 provides vehicle maintenance or repair analysis capabilities exceeding those onboard the portable device 110. The portable device 110 can include limited diagnostic capabilities that provide the ability to maintain or service the vehicle 102 in the field. In some instances, the repair and/or maintenance required by a vehicle 102 may involve comprehensive maintenance or repair procedures that are not included in the more routine maintenance procedures onboard the portable device 110. For example, the portable device 110 may provide a maintenance technician or vehicle crewmember a daily checklist of inspection items particular to a vehicle make and model. Such checklists may be temporally generated (e.g., daily, weekly, bi-weekly, and monthly checklists) or event driven checklists generated responsive to one or more detected vehicle conditions (e.g., a checklist that includes inspecting the vehicle drivetrain generated by the portable device 110 responsive to a detected high bearing temperature in the drivetrain). In at least some instances, the diagnostic system 130 uses the information provided via a checklist or similar user interface on the portable device 110 to analyze one or more aspects of a particular vehicle 102. Based on the results of the analysis performed by the diagnostics system 130, information regarding one or more maintenance and/or repair procedures is communicated to the portable device 110. In some instances, such as when a vehicle 102 is in a remote location removed from parts and material resources to complete the repair or maintenance procedure, such repair or maintenance information may take the form of expedient repairs or maintenance sufficient to permit the movement of the vehicle to a more fully equipped repair or maintenance facility.
In at least some instances, the diagnostics system 130 and the inventory logistics system 120 are communicably coupled 132. In such instances, the diagnostic system 130 may determine one or more parts and/or materials needed to perform a repair or maintenance procedure on a particular vehicle are not available at the vehicle's location or will not be available when the vehicle reaches the repair location. In such instances, by communicating data indicative of the parts and/or materials needed for the repair and/or maintenance procedure and the estimated time of arrival of the vehicle at the repair location to the inventory logistics system 120, the inventory logistics system 120 can acquire and route the parts and/or materials to the future vehicle repair location. Such integration can advantageously expedite the repair or maintenance process and reduce the vehicle downtime associated with performing the repairs or maintenance.
The vehicle deployment and positioning system 140 provides motor pool logistical information to the portable device 110. In some instances, the diagnostic system 130 may determine based on economic considerations, temporal considerations, or both, to deploy a replacement vehicle in lieu of repairing a damaged vehicle. In such instances, the vehicle deployment and positioning system 140 can provide information to the portable device regarding the availability, location, and estimated time of availability of the replacement vehicle. Large organizations, such as commercial fleet operators and military organizations frequently maintain a ready reserve of vehicles to replace those vehicles damaged, destroyed, or otherwise rendered unfit for service. Typically, such replacement vehicles are stored in one or more central storage locations, depots, warehouses, motor pools or the like. As replacements are needed in the field, vehicles are pulled from the central storage location and routed to a field location. The vehicle deployment and positioning system 140 provides data indicative of the type, number, and location of an organization's reserve supply of vehicles.
In at least some instances, the vehicle deployment and positioning system 140 and the diagnostics system 130 are communicably coupled 142. In such instances, the diagnostic system 130 may determine that the repairs or maintenance required by a particular field vehicle is too extensive and a replacement vehicle is preferable. In such instances, the diagnostics system may provide vehicle make, model, and/or type information to the vehicle deployment and positioning system 140. Responsive to the receipt of the information indicative of a vehicle make, model, and/or type, the vehicle deployment and positioning system 140 can dispatch a replacement vehicle from a motor pool or supply depot. In some instances, the inventory logistics system 120 can route the replacement vehicle provided by the vehicle deployment and positioning system 140 to the appropriate field location.
Within large fleet operations, standardized maintenance practices and procedures streamline servicing, ensure all vehicles receive in near uniform maintenance, and increase the operational availability of all vehicles within the fleet. Such standardized maintenance practices and procedures often originate with information provided by the vehicle manufacturer and/or equipment supplier. Standardized maintenance may include a variety of checklists tailored to routine or preventive maintenance performed in the field by a vehicle crewmember or at a service location by a maintenance technician. Standardized maintenance may also include checklists or instructions on repairing or restoring expected vehicle damage typically encountered during field operations (e.g., replacing a flat tire, swapping a radio, replacing a windshield).
Fleet operators create such maintenance and repair checklists and instructions based on manufacturer requirements, recommendations, and best practices. Maintenance and repair checklists and instructions are generally vehicle make and model specific. Maintenance and repair checklists used by a fleet operator are also tailored to the vehicles and are reflective of the expected operating conditions encountered by the vehicles. Thus, in addition to manufacturer or supplier based practices and procedures, such checklists are often customized by the fleet operator to reflect the operational experience of the fleet operator with a particular vehicle make and model and also based upon the expected service conditions that the vehicle will encounter.
Fleet operators will consider vehicle manufacturer and/or equipment supplier maintenance and repair requirements, recommendations, and best practices as a baseline in preparing maintenance and repair checklists and instructions. In addition to the requirements, recommendations, and best practices provided by the vehicle manufacturer and/or equipment supplier, the fleet operator can modify existing instructions or checklist items or provide additional instructions or checklist items based on operational experience and expected vehicle service conditions.
Many large organizations distribute checklists and instructions to maintenance and service personnel only after one or more levels of organizational review and approval. The review and approval process may include one or more divisional approvals to ensure adequate staffing, training, supplies, and materials are available to support the expected maintenance and repair needs of the vehicle fleet. For example, the personnel department may review checklists and instructions to ensure adequate staffing exists, to ensure staff training is adequate, and to coordinate additional training to support the maintenance and repair practices and procedures. A supply chain department may review checklists and instructions to ensure supplies needed to perform various maintenance and repair processes are at levels in in locations necessary to support fleet operations. Each of a number of organizational levels, groups, and/or departments approves or otherwise certifies the accuracy and/or content of each checklist and/or set of instructions prior to widespread distribution throughout the organization. Changes, alterations, additions, and/or revisions also pass through a similar approval process to ensure the organization maintains adequate human and material resources to facilitate fleet operations. Given the diversity of vehicles operated by an organization and the potentially large number of vehicles in the organization, developing checklists and instruction sets and tracking the various prerequisite approvals of each of the checklists and instruction sets presents a significant logistical hurdle.
In at least some instances, checklists and/or instruction sets may be developed in electronic format, for example using one or more asset authoring and distribution systems as described in U.S. Patent Application Ser. No. 61/861,887, filed Aug. 2, 2013 and U.S. Patent Application Ser. No. 61/865,463 filed Aug. 13, 2013, each of which are incorporated herein by reference in their entireties. Electronic checklists and/or instruction sets may be provided by the vehicle manufacturer and/or equipment supplier or may be generated by the fleet operator. As organizationally unapproved documents, such checklists and/or instruction sets must be reviewed and approved prior to distribution.
The Authoring Versioning Approval System 150 provides a system for tracking and providing notifications of pending and granted approvals for electronic documents such as checklists and instruction sets within an organization. In some instances, the Authoring Versioning Approval System 150 may include one or more optional components such as a document scanner or similar to facilitate the generation of electronic checklists and/or instruction sets from paper or similarly published documents. In other instances, the Authoring Versioning Approval System 150 may receive one or more electronic files containing data representative of one or more checklists and/or instruction sets 112. The fleet operator, the vehicle manufacturer, the equipment supplier or any combination thereof may generate the checklists and/or instruction sets 112 in whole or in part.
The Authoring Versioning Approval System 150 can route the received checklists and/or instruction sets 112 to the appropriate approval authorities within the fleet operator's organization. In some instances, such routing may include the generation and transmission of email or similar notifications that announce the availability of the checklists and/or instruction sets 112 for review and approval. In some instances, the Authoring Versioning Approval System 150 may establish due dates for review and approval and may follow up with periodic reminders of pending, unapproved, checklists and/or instruction sets 112. In some instances, the Authoring Versioning Approval System 150 may store or otherwise retain approved checklists and/or instruction sets 112 in a communicably coupled nontransitory storage to provide an evolutionary history for each checklist and/or instruction set 112.
After receiving organizational approval, the Authoring Versioning Approval System 150 communicates or otherwise transmits each checklist and/or instruction set 112 to the Authored Content Distribution System 160. The Authored Content Distribution System 160 distributes the approved checklists and/or instruction sets 112 to the appropriate recipients throughout the organization. In some instances, the Authored Content Distribution System 160 distributes checklists and/or instruction sets 112 specific to a particular vehicle make and model to the portions of the organization operating, maintaining and repairing those vehicles. The Authored Content Distribution System 160 may not routinely transmit checklists and/or instruction sets 112 not relevant to a particular group within an organization to the group however such checklists and/or instruction sets 112 may be distributed by the Authored Content Distribution System 160 to the portable device 110 upon request.
In addition to transmitting various checklists and/or instruction sets 112 throughout the organization, the Authored Content Distribution System 160 also tracks the version of the checklists and/or instruction sets 112 used by various groups within the organization to ensure the appropriate checklists and/or instruction sets 112 is in use. For example, a first group within the organization may be equipped with FV432 Mark I armored personnel carriers while a second group within the organization may be equipped with a number of later developed FV432 Mark III armored personnel carriers. The Authored Content Distribution System 160 can ensure the first group receives, loads, and uses the latest version of checklists and/or instruction sets 112 relevant to the FV432 Mark I, and the second group receives, loads and uses the latest version of checklists and/or instructions sets 112 relevant to the FV432 Mark III. The Authored Content Distribution System 160 also ensures the first and the second groups receive, load, and use checklists and/or instruction sets 112 relevant to both Mark I vehicles and Mark III vehicles.
The Auditing System 170 can audit field devices, including portable devices 110, to ensure the latest checklists and/or instruction sets 112 versions are in use by operating, maintenance, and repair personnel. Operational requirements, particularly for military organizations, may dictate that the portable devices 110 used by vehicle crews to perform checklist reviews and to plan, schedule, and/or perform vehicle field maintenance or repairs remain in a “dark mode” in which communications are disabled for operational security purposes. Since the Authored Content Distribution System 160 can distribute revised checklists and/or instruction sets 112 at any time, the possibility exists that at least some checklists and/or instruction sets 112 will be issued when the portable devices 110 are in dark mode. In other instances, vehicles may be operating in remote areas (e.g., an oilfield environment in remote northern Canada) having no or unreliable communications and one or more checklist and/or instruction set 112 updates may be missed or only partially received by the portable device 110. In such instances, the Auditing System 170 will confirm the latest versions of any checklists and/or instruction sets 112 relevant to the vehicles associated with a particular portable device 110 are loaded when the portable device 110 establishes a communicable coupling to the network 114.
In at least some implementations, the above-described functionality of the Inventory Logistics System 120, Diagnostics System 130, Vehicle Deployment and Positioning System 140, Authoring Versioning Approval System 150, Authored Content Distribution System 160, and Auditing System 170 may be combined as modules or the functional equivalent thereof into one or more systems such as an Enterprise Management system. While not explicity illustrated as such, the network 114, or some other network, may provide access to computer systems of one or more original equipment manufacturers (OEMs), for instance a manufacturer of the vehicle. Such may, for example, take the form of an OEM/MOD Web portal, which provides access to manufacturer related information such as system design documents, manuals, charts, diagnostic procedures, parts lists, etc. Such may provide access to authored content, which may or may not be proprietary content.
Although not required, the embodiments will be described in the general context of computer-executable instructions, such as program application modules, objects, or macros being executed by a computer. Those skilled in the relevant art will appreciate that the illustrated embodiments as well as other embodiments can be practiced with other computer system configurations, including hand-held devices, multiprocessor systems, microprocessor-based or programmable consumer electronics, personal computers (“PCs”), network PCs, mini computers, mainframe computers, and the like. The embodiments can be practiced in distributed computing environments where tasks or modules are performed by remote processing devices, which are linked through a communications network. In a distributed computing environment, program modules may be located in both local and remote memory storage devices.
The back-end system 210 may take the form of a conventional mainframe or mini-computer that includes a processing unit 212, an at least partially nontransitory system memory 214 and a system bus 216 that couples various system components including the system memory 214 to the processing unit 212. The back-end system 210 will at times be referred to in the singular herein, but this is not intended to limit the embodiments to a single back-end system since in typical embodiments, there will be more than one back-end system or other device involved. The computing environment may employ other computers, such as conventional personal computers, where the size or scale of the system allows.
The processing unit 212 may be any logic processing unit, such as one or more central processing units (CPUs), digital signal processors (DSPs), application-specific integrated circuits (ASICs), etc. Unless described otherwise, the construction and operation of the various blocks shown in
The system bus 216 can employ any known bus structures or architectures, including a memory bus with memory controller, a peripheral bus, and a local bus. The system memory 214 includes read-only memory (“ROM”) 218 and random access memory (“RAM”) 220. A basic input/output system (“BIOS”) 222, which can form part of the ROM 218, contains basic routines that help transfer information between elements within the back-end system 210, such as during start-up.
The back-end system 210 also includes a hard disk drive 224 for reading from and writing to a hard disk 226, and an optical disk drive 228 and a magnetic disk drive 230 for reading from and writing to removable optical disks 232 and magnetic disks 234, respectively. The optical disk 232 can be a CD-ROM, while the magnetic disk 234 can be a magnetic floppy disk or diskette. The hard disk drive 224, optical disk drive 228 and magnetic disk drive 230 communicate with the processing unit 212 via the system bus 216.

The one or more communications interfaces 282 can include one or more Bluetooth® interfaces, one or more near field communications (“NFC”) interfaces, one or more cellular interfaces, or any other RF or microwave interface capable of supporting a data exchange with an external device such as a vehicle 102. The one or more communications interfaces 282 can also include one or more tethered communications interfaces such as an IEEE 1394 (“Firewire”) interface, a USB interface, or similar standard or proprietary interface capable of supporting a data exchange with an external device such as a vehicle 102. In at least some implementations, any number of communications interfaces 282 may be in simultaneous use by the portable device 110. For example, a vehicle 102 may communicate vehicle identification and system data to complete a vehicle checklist 112 appearing on the portable device 110 via a wireless IEEE 802.11 communications interface 282. At the same time, the portable device 110 may communicate the checklist information to a back-end system 210 via a global system for mobile devices (“GSM”) cellular communications interface 282.
A system operator such as a maintenance technician or vehicle crewmember can enter commands and information into the portable device 110 by providing input to a user interface 286 through input devices such as a touch screen or keyboard 290 and/or a pointing device such as a mouse 288. Other optional input devices can include a microphone, joystick, game pad, tablet, scanner, etc. These and other input devices are communicably coupled to the processor 270 through an interface such as a universal serial bus (“USB”) interface that couples to the system bus 268, although other interfaces such as a parallel port, a game port or a wireless interface or serial port can be used. A display device 284 is coupled to the system bus 268. The portable device 110 can include other optional output devices, such as speakers, printers, etc.
The portable device 110 displays a vehicle checklist and/or instruction set 112 specific to a particular vehicle for completion either autonomously (e.g., checklist completion via data transfer from one or more vehicle onboard communications systems), manually (e.g., the crewmember or maintenance technician manually enters vehicle data into the portable device 110), or some combination thereof. The acquired or entered data received by the portable device 110 is logically associated with an identifier from the originating vehicle and stored in a nontransitory storage media for subsequent transmission to a back-end system 210. The checklist generation and data collection method commences at 302.
At 304, the portable device 110 receives data indicative of the make and model of a particular vehicle 102. In some instances, the vehicle 102 communicates information indicative of the make and model (e.g., a vehicle identification number or similar assigned defined identifier) to the portable device 110 via a tethered or wireless connection. In some instances, the crewmember or user completing the checklist on the portable device 110 enters information indicative of the make and model via a user interface 286.
At 306, responsive to the receipt of an input indicative of the vehicle make and model, the portable device 110 displays user interface including a checklist and/or instruction set 112 specific to the vehicle make and model. In some instances, the portable device 110 retrieves one or more checklists and/or instruction sets 112 from the non-transitory memory 278 and/or drives 280. In some instances, the portable device 110 retrieves one or more checklists and/or instruction sets 112 from a remote non-transitory storage location, such as from a non-transitory storage location in the backend system 210. The checklists and/or instruction sets 112 retrieved by the portable device are specific to a particular vehicle make and model. Such advantageously ensures the collection of data relevant to a particular vehicle, specifically data relevant to particular maintenance and/or repairs useful in maintaining the vehicle at a high level of operational readiness.
At 308, via the user interface 286 the crewmember or maintenance technician completes the checklist and/or instruction 112 presented on the portable device 110 display 284. In some instances, the crewmember or maintenance technician provides input to the portable device 110 via a touchscreen display. In some instances, the crewmember or maintenance technician provides input to the portable device 110 via either a physical or virtual keyboard or similar data input device 290. In some instances, the crewmember or maintenance technician provides input to the portable device 110 via any other input device, such as voice command or the like.
At 310, the data acquired by the portable device 110 is stored in a non-transitory memory. In at least some instances, such data may be stored locally in the non-transitory memory or drives 280 disposed in the portable device 110. In some instances, such data may be stored remotely in a non-transitory memory or drive coupled to one or more back end systems 210. Retaining such information in a non-volatile, non-transitory storage medium advantageously permits the development of a complete vehicle repair and maintenance history.
At 312, the portable device 110 communicates all or a portion of the acquired data stored in the non-transitory memory or drives 280 to one or more remote systems, such as one or more backend systems 210. Such data can include a vehicle identifier unique to a particular vehicle 102 and all or a portion of the data received by one or more checklists and/or instruction sets 112 logically associated with the identified vehicle 102.
In some instances, the data collected by the one or more checklists and/or instruction sets 112 is transmitted in real-time or near real-time to one or more back-end systems 210. In other instances, for example when out of communication with one or more networks or observing “radio silence” protocol, the data collected by the one or more checklists and/or instruction sets 112 is transmitted on a delayed basis to the one or more back-end systems 210, for example when communications are restored or when radio silence protocol is no longer observed. The ability to accommodate for times when a piece of equipment (e.g., a vehicle) is either out of communications, for example being outside a range of communications or operating in a “radio silence” mode is particular advantageous. In such situations, the ability to function autonomously, for instance via stored authored content allows continued operation. The ability of automatically update authored content once communications is reestablished ensures that the most up to date authored content is available, and stored in anticipation of further loss of communications. The method 300 concludes at 314.
At 404, the portable device 110 identifies the role of the system user. In some instances, the system user can provide information via touchscreen or keyboard that is indicative of the user's role. In other instances, the user may cause the portable device 110 to read one or more identification media using one or more communicably coupled media readers (e.g., mag-stripe card readers, radio frequency interrogators, near field communication transceivers). In yet other instances, the portable device 110 may include one or more biometric input devices able to read one or more physiological parameters of indicative of the system user to identify the system user autonomously.
The portable device also identifies the make and model of a particular vehicle scheduled for maintenance or repairs, for example using one or more techniques discussed at 304. Based at least in part on the identified system user's role and based on the identified make and model of the particular vehicle requiring maintenance or repairs, the portable device 110 selects one or more checklists or instruction sets at 406. In some instances, the portable device 110 can provide instructional or informative supplemental information as part of the user interface 286. Such supplemental information can include illustrations, animations, audio, video, and multimedia presentations containing information commensurate with the system user's technical expertise and useful in performing the maintenance or repairs detailed in the checklists and/or instruction sets 112 presented in the user interface 286.

In some instances, the acquired vehicle data and vehicle identification information may be transmitted in real-time or near real-time to the remote recipient. In other instances, for example when a radio silence policy is in effect, the acquired vehicle data and vehicle identification information the checklist may be stored locally on the portable device 110 for subsequent transmission to the remote recipient. The data transfer from the portable device 110 to the back-end system 210 may be executed as a background task by the portable device operating system. In such instances, the system user may be unaware that the data transfer has occurred.
At 506, a synchronization message is generated on the display 284 of the portable device 110. In some instances, the back-end system 210 generates and transmits the synchronization message to the portable device 110 upon successful receipt of the acquired vehicle data and the vehicle identification information from the portable device 110. In other instances, the portable device 110 generates synchronization message upon successful completion of the transmission of acquired vehicle data and vehicle identification information to the back-end system 210. Given the at times asynchronous transmission of acquired vehicle data in vehicle identification information, the synchronization message advantageously provides the system user with an indication that data successfully transferred from the portable device 110 to the back-end system 210. The method 500 for transmitting vehicle specific data from portable device 110 to a back-end system 210 and generating a synchronization message indicative of data transfer success concludes at 508.
At 604, one or more vehicular communications interfaces communicate information including data indicative of vehicle system data and vehicle identification information to the portable device 110. The vehicular communications interfaces may include one or more tethered interfaces, one or more wireless interfaces, or any combination thereof. In some instances, a wireless vehicular communications interface may automatically connect or communicably couple to the portable device 110. Upon connection, the portable device 110 will confirm the vehicle identification information supplied by the vehicle corresponds to the checklist 112 vehicle identification information displayed on the portable device 110. After confirming the correct vehicle, as identified using the vehicle identification information, has connected to the portable device 110 the vehicle transmits vehicle system information to the portable device 110 via the wireless communications interface.
In a similar manner, a vehicle 102 can initially communicate vehicle identification information via a tethered communications interface to a portable device 110. Upon receipt of the vehicle identification information from the vehicle, the portable device 110 will confirm the vehicle identification information supplied by the vehicle corresponds to the checklist 112 vehicle identification information. After confirming the correct vehicle as identified using the vehicle identification information, has connected to the portable device 110 the vehicle transmits vehicle system information to the portable device 110 via the tethered communications interface.
At 606, the portable device 110 populates the one or more checklists 112 with vehicle system information received by the portable device 110. The method 600 of automatically receiving vehicle specific data from the vehicle and populating one or more checklists 112 with the received data concludes at 608.
At 704, the vehicle 102 communicates a message including data indicative of the condition of the vehicle to a portable device 110 logically associated with the vehicle 102. The vehicle condition data may include vehicle identification data, vehicle system data, and other data helpful in assessing the overall service condition and/or field reparability of the vehicle by the portable device 110 and/or a remote recipient, such as a back-end system 210. In at least some instances, the vehicle condition data transmitted from the vehicle to the portable device 110 includes vehicle system data sufficient to determine whether field repairs are possible or whether assignment of a replacement vehicle is appropriate.
At 706, the portable device 110 communicates all or a portion of the message including data indicative of the condition of the vehicle to a remote recipient, such as the back-end system 210. The method 700 of automatically receiving data from a vehicle indicative of the vehicle's condition in communicating the received vehicle condition data to one or more remote recipients concludes at 708.
At 804, a back-end system 210 receives a number versions of vehicle related authored content. For example, an Authoring Versioning Approval System 150 forming at least a portion of the back-end system 210 can receive the number of versions of vehicle related authored content. In at least some instances, the vehicle related authored content includes one or more checklists and/or instruction sets 112. A vehicle manufacturer and/or equipment supplier may communicate or otherwise transmit the number versions of vehicle related authored content to the back-end system 210. In at least some instances, each of the number of versions of vehicle related authored content associated with a particular vehicle configuration, a particular vehicle component, a particular vehicle system, and/or a particular vehicle make and model.
At 806, the back-end system 210 stores each of the number of versions of vehicle related authored content in a non-transitory storage media. The Authoring Versioning Approval System 150 generates and communicates notifications to one or more approval authorities. Each of these notifications contains information on the vehicle related authored content requiring approval by the authority. Each of the notifications may also contain a link to the stored vehicle related authored content requiring approval or may containing a copy of the vehicle related authored content requiring approval.
At 808, after receiving all required approvals the Authoring Versioning Approval System 150 communicates the approved vehicle related authored content to the Authored Content Distribution System 160 for distribution to some or all of the portable devices 110 used by crewmembers and/or maintenance personnel to maintain and repair the vehicles 102. In some instances, the Authored Content Distribution System 160 communicates to each of the portable devices 110 the vehicle related authored content relevant to only those vehicles 102 logically associated with the portable device. Thus, for example, a portable device 110 logically associated with personnel assigned to a unit equipped with Stryker Armored Fighting Vehicles (“AFVs”) would receive checklists and/or instruction sets 112 logically associated with Stryker AFVs but would not receive checklists and/or instruction sets 112 logically associated with M1A2 Abrams main battle tanks.
At 810, the Authored Content Distribution System 160 tracks the approved versions of the vehicle related authored content received from the Authoring Versioning Approval System 150. By tracking the various approved versions of vehicle related authored content, the Authored Content Distribution System 160 confirms that the checklists and instruction sets 112 used by each portable device 110 are the most recent revisions relevant to the vehicles 102 logically associated with the portable device 110.
At 812, the Authored Content Distribution System 160 beneficially pushes the latest approved version to those portable devices 110 logically associated with the vehicle or vehicles associated with the most recent version of the vehicle related authored content. The method 800 of generating versions of vehicle related authored content and tracking the distribution of approved versions of the vehicle related authored content across any number of portable devices used for vehicle repair and/or maintenance concludes at 814.
To ensure portable device user compliance with organizational goals or requirements, the Auditing System 170 continuously or intermittently polls some or all of the portable devices 110. During the polling process, the portable device 110 communicates data indicative of the versions of vehicle related authored content stored in the portable device 110 to the Auditing System 170. The Auditing System uses the received data to determine whether the portable device 110 contains the latest versions of vehicle related authored content relevant to the vehicles logically associated with the portable device 110.

In some instances, the compliance audit collects data indicative of the vehicles logically associated with the portable device 110 and data indicative of the versions of any checklists and/or instruction sets 112 used by the portable device 110. The Auditing System 170 compares the vehicle data and the checklist and/or instruction set 112 version data to ensure the most recent revision of the checklist and/or instruction set 112 relevant to the vehicles logically associated with the portable device 110 are loaded on the portable device 110.
In some instances, the Auditing System 170 collects compliance audit data from all field deployed portable devices 110, including those portable devices 110 that have previously indicated receipt of the most recent versions of the vehicle checklists and/or instruction sets 112. In other instances, the Auditing System collects compliance audit data from only those field deployed portable devices 110 that have not indicated receipt of the most recent versions of the vehicle checklists and/or instruction sets 112.
At 906, the Auditing System 170 communicates the compliance audit synchronization data to the back-end system 210. Responsive to the receipt of the compliance audit synchronization data the back-end system 210 may cause the Authored Content Distribution System 160 to communicate the appropriate most recent revision of the vehicle related authored content to each portable device 110 that has not indicated receipt of the most recent version(s) of the vehicle checklists and/or instruction sets 112. The method 900 of collecting compliance audit synchronization data from some or all portable devices 110 concludes at 908.
At 1004, the back-end system 210 receives vehicle system data and vehicle identification data. In some instances, a portable device 110 assigned to a vehicle crewmember or vehicle maintenance personnel collects the data using one or more checklists and/or instruction sets 112.
At 1006, the back-end system 210 analyzes the received vehicle system data. In some instances, the Diagnostics System 130 can receive and analyze all or a portion of the vehicle system data and vehicle identification data communicated by the portable device 110.
At 1008, the back-end system 210 generates an analytical result based on the vehicle system data supplied by the portable device 110. In some instances, the Diagnostic System 130 generates the analytical result. The Diagnostic System 130 may optionally communicate to the Inventory Logistics System 120 data indicative of parts or materials needed to maintain or repair the vehicle based at least in part on the generated analytical result. Responsive to the receipt of the parts and/or materials data from the Diagnostic System 130, the Inventory Logistics System 120 acquires and delivers the needed parts and/or materials to the vehicle's location.
At 1010, the back-end system 210 communicates data indicative of the analytical result to the portable device associated with the vehicle. Such analytical result data provides the portable device user with information on required or recommended vehicle repairs and/or maintenance. In some instances, where data indicative of predicted maintenance or repairs is provided, the back-end system 210 can also provide the portable device user with an estimated duration until maintenance or repairs are due and a location where the parts and materials needed to perform the maintenance and repairs are available. The method 1000 of transmitting vehicle related data collected using a portable device 110 to a back-end system 210 for analysis, and communicating data indicative of the analytical result generated by the back-end system 210 to the portable device 110 concludes at 1012.

At 1106, the Inventory Logistics System 120 receives data indicative of one or more parts and/or materials required to repair or maintain one or more vehicles 102. In some instances, using analytical result data generated using acquired vehicle system data the Diagnostics System 130 either alone or in cooperation with the Inventory Logistics System 120, determines one or more parts and/or materials needed to repair or maintain a vehicle 102. After determining the parts and/or materials needed, the Diagnostics System 130 communicates all or a portion of the data indicative of the needed parts and/or materials to the Inventory Logistics System 120.
In some instances, using on acquired vehicle system data from one or more vehicles 102, the portable device 110 communicates all or a portion of the data indicative of one or more parts and/or materials required to repair or maintain one or more vehicles 102 to the Inventory Logistics System 120. In some instances, the portable device user communicates all or a portion of the data indicative of one or more parts and/or materials required to repair or maintain one or more vehicles 102 to the Inventory Logistics System 120.
At 1108, the Inventory Logistics System 120 determines the location of the parts and/or materials requested by the Diagnostic System 130, the portable device 110, and/or the portable device user. In addition, the Inventory Logistics System 120 may optionally determine the date when the needed parts will be available at the field location of the vehicle. The back-end system 210 communicates data indicative of the parts and/or materials needed to repair or maintain the vehicle 102, the time at which the parts and/or materials will be available, and optionally the location at which the parts and/or materials will be positioned to the portable device 110 associated with the respective vehicle 102. The method 1100 of determining the location of parts and/or materials needed for repair of one or more vehicles and specifying at least one of the date and time that the parts and/or materials are needed or a location where the parts and/or materials are needed concludes at 1110.
At 1204, the back-end system 210 determines the need for deployment of a replacement vehicle from a vehicle motor pool, warehouse, or depot based on received data indicative of field-positioned vehicle system data and/or field-positioned vehicle condition. In at least some instances, the Diagnostic System 130 can assess the data indicative of field-positioned vehicle system data and/or field-positioned vehicle condition to determine the need for deployment of a replacement vehicle from a vehicle motor pool, warehouse, or depot. For example, responsive to the receipt of data indicative of a comprehensive engine failure in a Challenger II main battle tank, the Diagnostic System 130 may determine the technical expertise of the crewmembers or maintenance personnel associated with the vehicle are insufficient to perform remedial engine repairs. In such instances, the Diagnostic System 130 can provide data to the Vehicle Deployment Positioning System 140 that includes the type and location of the vehicle.
At 1206, the Vehicle Deployment Positioning System 140 requests deployment of a replacement vehicle 102 from a vehicle motor pool, warehouse, or depot. In at least some instances, the Vehicle Deployment Positioning System 140 can transmit to the portable device 110 information indicative of the replacement vehicle identification, a time at which the replacement vehicle will be available, and/or a location at which the replacement vehicle will be available. The method 1200 of determining the need for deployment of a replacement vehicle 102 based on the acquired vehicle system data and/or the acquired vehicle condition data provided by the portable device 110 associated with a particular vehicle 102 concludes at 1208.

Such vehicle related authored content may include one or more checklists and/or instruction sets 112 logically associated with a particular vehicle version (e.g., 2009 GMC Sierra pick-ups) included in the motor pool of a fleet operator. The vehicle manufacturer or equipment supplier physically or electronically transmits the new version of vehicle related content to a back-end system 210 for review and approval prior to general distribution via field-deployed portable devices carried by crewmembers or maintenance personnel. In at least some instances, the Authoring Versioning Approval System 150 can receive all or a portion of the vehicle related authored content published by the vehicle manufacturer or equipment supplier.
At 1306, the Authoring Versioning Approval System 150 forwards the received vehicle related authored content to one or more defined approval authorities for review and approval. Such an approval process may include multiple parallel approvals or a number of sequential approvals by various approval authorities within the fleet operator's administrative organization. As approvals are received from each of the approval authorities, the Authoring Versioning Approval System 150 stores data indicative of the approval in a nontransitory storage memory communicably coupled to the back-end system 210.
At 1308, the Authoring Versioning Approval System 150 identifies those approval authorities from whom approval for a new version of vehicle related authored content is pending.
At 1310, the Authoring Versioning Approval System 150 generates data indicative of one or more approval authorities from whom approval is pending. In at least some implementations, the Authoring Versioning Approval System 150 transmits notifications including a message reminding the approval authority of the new version of vehicle related authored content awaiting their approval. The method 1300 of tracking and approving various versions of vehicle related authored content concludes at 1312.
