DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS




The present invention provides a system and methods to allow multiple stations in geographically dispersed locations to monitor and track vehicle repair record and service status information regardless of vehicle location.





FIG. 1

illustrates the overall arrangement of a preferred embodiment of a vehicle tracking system


100


according to the present invention. Referring now to

FIG. 1

, vehicle tracking system


100


includes a central equipment manager


101


, regional communications terminals


102


, and local communications terminals


103


. Preferably, a single regional communications terminal


102


is allocated to support a given particularly-bounded geographical region. For example,

FIG. 1

shows three regions (Regions A, B, and C) each having a regional communications terminal


102


. However, one or more additional regional communications terminals


102


may provide backup communications and processing for one or more regions.




Each regional communications terminal


102


is preferably located in a regional company office or other such location having responsibility for maintaining and servicing the vehicles within a particular geographical region or regions. Each local communications terminal


103


is preferably located in a repair and service station having responsibility for repairing broken-down or out-of-service vehicles, as well as for providing routine service and preventive maintenance, for vehicles temporally within that region. A local communications terminal


103


communicates with a regional communications terminal


102


within its local region; however, a given local communications terminal


103


may communicate with one or more regional communications terminals


102


within or outside of its local region. Regional communications terminal


102


is thus provided in shared communication with multiple local communications terminals


103


.





FIG. 2

further illustrates the logical relationships among these elements of vehicle tracking system


100


. Referring now to

FIG. 2

, each regional communications terminal


102


communicates with central equipment manager


101


. Central equipment manager


101


maintains at a single office location vehicle service status information for all regions, and periodically disseminates this information to all regional communications terminals


102


and local communications terminals


103


.




In a preferred embodiment, each regional communications terminal


102


communicates with central equipment manager


101


and multiple local communications terminals


103


using a frame relay network


104


. Frame relay is a packet-switched protocol used for connecting terminals to a Wide Area Network (WAN) supporting T-1 or T-3 data rates. Alternatively, frame relay network


104


comprises public switched or private telecommunications circuits such as telephone landlines, the Internet, or wireless transmission systems including, but not limited to, personal communications services, cellular data, satellite, or point-to-point microwave communications. Regional communications terminals


102


are interconnected via frame relay network


104


.




Referring again to

FIG. 2

, vehicle tracking system


100


includes a vehicle status database


200


operably coupled to each local communications terminal


103


and regional communications terminal


102


. A vehicle status database


200


is also operably coupled to central equipment manager


101


. In a preferred embodiment, central equipment manager


101


is a mainframe computer system, such as a DEC® VAX™ or IBM® Model 3070 system, having a frame relay gateway and an Internet interface. Alternatively, central equipment manager


101


is implemented according to a client-server architecture. Central equipment manager


101


preferably communicates with regional communications terminals


102


via frame relay network


104


and with local communications terminal


103


via Internet interface


108


.




Central equipment manager


101


transmits a multiple breakdown advisory


215


(see

FIG. 6

) to all local communications terminals


103


and all regional communications terminals


102


, preferably once per 24-hour period. Central equipment manager


101


transmits a multiple breakdown advisory


215


to local communications terminals


103


as a database file via File Transfer Protocol (FTP) using Internet interface


108


. Preferably, central equipment manager


101


transmits multiple breakdown advisory


215


to regional communications terminals


102


as a database file via frame relay network


108


. Users at repair/service locations having local communications terminal


103


are able to withhold rental of vehicles listed on multiple breakdown advisory


215


if, in the user's judgment, the vehicle's repair history indicates a high likelihood of break-down during an extended trip such as, for example, an inter-regional or cross-country trip. This allows an operator of vehicle tracking system


100


to achieve higher overall customer satisfaction and to save money on operating costs such as vehicle towing.




Preferably, multiple breakdown advisory


215


is also used to indicate additional conditions affecting the status of a given vehicle such as, but not limited to, a stolen or missing vehicle. For example,

FIG. 17

illustrates a preferred advisory warning generated by local communications terminal


103


and regional communications terminal


102


in response to receiving a multiple break-down advisory


215


from central equipment manager


101

Referring again to

FIG. 2

, a local communications terminal


103


typically provides vehicle service status file


205


to a single regional communications terminal


102


. However, as shown in

FIG. 2

, local communications terminal


103


may alternatively provide vehicle service status file


205


to multiple regional communications terminals


102


located in different regions. The latter situation may occur, for example, when local communications terminal


103


is located sufficiently physically proximate to two or more regional communications terminals


102


such that it is advantageous for that repair/service location to support vehicles within the control span of either or both regional offices.

FIG. 4

describes the contents of vehicle status database


200


. Referring now to

FIG. 4

, vehicle status database


200


includes one or more vehicle service status files


205


, a vehicle history file


210


, and multiple break-down advisory


215


.





FIG. 6

illustrates the flow of vehicle repair and service status information comprising vehicle status database


200


throughout vehicle tracking system


100


, as described herein.




Vehicle service status file


205


is comprised of one or more service event notifications


220


. A service event notification


220


is created or modified by a user, usually a service professional, at a local repair or service location by logging vehicle repair and service information using local communications terminal


103


. Referring again to

FIG. 4

, service event notification


220


may include, for example, a control number


225


, a vehicle identifier

, an equipment type indicator


235


, current status


240


, location identifier


245


, date-in-building indicator


250


, type-of-service-required indicator


255


, an availability prediction


260


, and remarks


265


.




In a preferred embodiment, local communications terminal


103


provides for generation of availability prediction


260


by calculating an average repair/service time for the particular location and providing this information to the user. To calculate the average repair/service time, local communications terminal


103


retrieves from vehicle status database


200


service event notifications


220


for repair/service activities accomplished at this service location during the past thirty days. Local communications terminal


103


then computes an average repair/service time by averaging the number of days from date-in-building


250


to closing of the service event notification


220


for each service event notification within the thirty day period.

FIG. 19

illustrates a preferred display of the calculated repair/service time provided by local communications terminal


103


. Alternatively, a period of time of shorter or longer duration than thirty days is used in calculating the average repair/service time. Preferably, the average repair/service time is calculated daily. Local communications terminal


103


displays the calculated average repair/service time to the user. Local communications terminal


103


further includes an operator interface that allows the user to enter availability prediction


260


using a keyboard, the user having considered a variety of factors including the average repair/service time.




In a first alternative, local communications terminal


103


calculates availability prediction


260


based on, without limitation, the mean-time-to-repair (typically measured in hours) to complete a particular service job for a particular item of equipment. In this alternative embodiment, vehicle status database


200


further includes a set of mean-time-to-repair values indexed by equipment type


235


and type-of-service-required


255


. Mean-time-to-repair values are periodically updated in response to changes in the calculated average repair/service time described above. Local communications terminal


103


sets availability prediction


260


equal to the mean-time-to-repair value associated with the particular equipment type


235


and type-of-service-required


255


. Local communications terminal


103


may modify availability prediction


260


based upon user-provided factors such as, but not limited to, the service backlog at this location, staffing levels at this location, and parts availability.




In a second alternative embodiment, local communications terminal


103


automatically calculates availability prediction


260


by setting availability prediction


260


equal to the date occurring three business days following the date service event notification


220


is entered into vehicle service database


200


. Local communications terminal


103


further includes an operator interface that allows a user to modify availability prediction


260


by manually entering a different projected availability date using a keyboard.




Local communications terminal


103


stores availability prediction


260


with its associated service event notification


220


record using vehicle status database


200


. In a preferred embodiment, availability prediction


260


is included in the service event notification


220


record as shown in FIG.


4


. Alternatively, the service event notification


220


record includes a pointer to a memory location containing availability prediction


260


.





FIG. 5

shows a preferred control number


225


for use with vehicle tracking system


100


. Referring now to

FIG. 5

, control number


225


is formed by sequentially concatenating two numeric digits corresponding to the current month, two numeric digits corresponding to the current day of the month, and a three-digit sequential service number


275


. Service number


275


is preferably determined by local communications terminal


103


at the time the user enters a new service event notification


220


. A distinct control number


225


is provided for each service request for an individual vehicle. Control number


225


thus patently conveys to an observer an indication of: (1) the date that a particular service event notification


220


was created for the associated vehicle, and (2) the order in which that service event notification


220


was created with respect to other service event notifications


220


logged by that local communications terminal


103


on a particular date.




Referring again to

FIG. 4

, vehicle service status file


205


is comprised of the service event notifications


220


entered or modified at a local communications terminal


103


since the last time vehicle service status file


205


was uploaded to regional communications terminal


102


. In a preferred embodiment, vehicle service status file


205


is created by local communications terminal


103


immediately prior to uploading it to regional communications terminal


102


. Local communications terminal


103


creates vehicle service status file


205


by formulating a query requesting retrieval all of the service event notifications


220


entered or modified (e.g., service ticket closed at the completion of repair, service location changed) since the time of the most recent upload. The retrieved service event notification


220


records are then stored as vehicle service status file


205


using vehicle status database


200


.




Referring again to

FIG. 6

, vehicle service status file


205


is then uploaded to regional communications terminal


102


using frame relay network


104


. In a preferred embodiment, local communications terminal


103


automatically uploads vehicle status file


205


periodically at a frequency of once every 30 minutes. Alternatively, the frequency of upload can be decreased to minimize the number of transmissions or increased to approach real-time notification. Personnel at regional company offices use regional communications terminal


102


to determine equipment status and location in order to manage reservations. For example, if equipment is scheduled to be serviced in a particular region, personnel at other regions will not reserve that vehicle for an inter-regional trip.




Regional communications terminal


102


aggregates each of the vehicle status files


205


received from local communications terminals


103


into a vehicle service status report


285


. Regional communications terminal


102


then transmits vehicle service status report


285


to central equipment manager


101


. In a preferred embodiment, regional communications terminal


102


automatically uploads vehicle service status report


285


periodically at a frequency of once every 30 minutes. In a preferred embodiment, vehicle service status report
