Abstract

Various embodiments of the present invention provide systems and methods for managing fault codes triggered by one or more vehicles during operation. In general, various embodiments of the invention involve recording and analyzing fault codes triggered during a particular time period while a vehicle is in operation. As a result of the analysis, various embodiments of the invention may set a state for each of the identified fault codes, the state indicating a level of action to address the identified fault code. In particular embodiments, the states may be one of a caution state indicating one or more components or sub-systems of the vehicle should be monitored, a critical state indicating one or more components or sub-systems of the vehicle should be repaired, or an environmental state indicating failure or potential failure of one or more components or sub-systems of the vehicle may affect one or more environmental conditions.

Claims

1. A system for managing fault codes associated with a vehicle, the system comprising:

a memory storing a plurality of parameters and a plurality of fault codes, wherein each parameter is associated with a fault code and said plurality of parameters comprise;

an upper limit and a lower limit associated with a particular fault code, the upper limit and lower limit defining a range of a number of times the particular fault code is generated during a predefined time period the vehicle was in operation; and

one or more computer processors configured to;

receive fault code information retrieved from the vehicle, the fault code information comprising one or more of said plurality of fault codes, the one or more fault codes generated during a particular time period the vehicle was in operation;

retrieve parameters stored in the memory associated with the one or more fault codes;

analyze the fault code information to identify each of the one or more fault codes signaling failure or potential failure of one or more components or sub-systems of the vehicle based at least in part on the parameters associated with the one or more fault codes in the fault code information; and

set a state for each identified fault code, based at least in part on the parameters associated with each identified fault code, the state indicating a level of action associated with the identified fault code, wherein the state for the particular fault code is set by the processors in response to the fault code information showing that the particular fault code was generated a number of times within the range defined by the upper limit and lower limit during the predefined time period.

2. The system of claim 1, wherein the state comprises one of a caution state indicating the one or more components or sub-systems of the vehicle should be monitored, a critical state indicating the one or more components or subsystems of the vehicle should be repaired, or an environmental state indicating the failure or potential failure of the one or more components or sub-systems of the vehicle affects one or more environmental conditions.

3. The system of claim 1, wherein the one or more computer processors are configured to send one or more notifications to one or more parties for each of the identified fault codes, the one or more notifications comprising the state for each of the identified fault codes.

4. The system of claim 1, wherein the one or more computer processors are configured to initiate a work order for repair of at least one of the one or more components or sub-systems of the vehicle.

5. The system of claim 1, further comprising an interface configured to provide access to one or more procedures for diagnosing the one or more components or sub-systems associated with each of the identified fault codes.

6. The system of claim 5, wherein the interface is further configured to display comments provided by one or more individuals on performing the one or more procedures for diagnosing the one or more components or sub-systems.

7. The system of claim 5, wherein the interface is further configured to provide a map displaying the GPS coordinates of the vehicle.

8. The system of claim 5, wherein the interface is further configured to display results of performing the one or more procedures for diagnosing the one or more components or sub-systems.

9. The system of claim 1, further comprising an interface configured to provide access to one or more maintenance procedures associated with each of the identified fault codes.

10. The system of claim 9, wherein the interface is further configured to display results of performing the one or more maintenance procedures.

11. A system for managing fault codes associated with a vehicle, the system comprising:

a memory storing a plurality of parameters and a plurality of fault codes, wherein each parameter is associated with a fault code and said plurality of parameters comprise;

a threshold value and a consecutive value associated with the particular fault code, the threshold value defining a threshold number of times the particular fault code is generated during the predefined time period the vehicle was in operation and the consecutive value defining a number of consecutive predefined time periods during which the threshold value was met or exceeded; and

one or more computer processors configured to;

receive fault code information retrieved from the vehicle, the fault code information comprising one or more of said plurality of fault codes, the one or more fault codes generated during a particular time period the vehicle was in operation;

retrieve parameters stored in the memory associated with the one or more fault codes;

analyze the fault code information to identify each of the one or more fault codes signaling failure or potential failure of one or more components or sub-systems of the vehicle based at least in part on the parameters associated with the one or more fault codes in the fault code information; and

set a state for each identified fault code, based at least in part on the parameters associated with each identified fault code, the state indicating a level of action associated with the identified fault code, wherein the state for the particular fault code is also set by the processors in response to the fault code information showing that the particular fault code was generated a number of times meeting or exceeding the threshold value during a number of consecutive time periods meeting or exceeding the consecutive value.

12. The system of claim 11, wherein the state comprises one of a caution state indicating the one or more components or sub-systems of the vehicle should be monitored, a critical state indicating the one or more components or subsystems of the vehicle should be repaired, or an environmental state indicating the failure or potential failure of the one or more components or sub-systems of the vehicle affects one or more environmental conditions.

13. The system of claim 11, wherein the one or more computer processors are configured to send one or more notifications to one or more parties for each of the identified fault codes, the one or more notifications comprising the state for each of the identified fault codes.
