Systems and methods of determining causes of performance deficiencies of vehicles
First Claim
1. A method of determining causes of performance deficiencies of an off-road vehicle, comprising:
- determining whether the vehicle is in a full-pull condition;
measuring a ground speed of the vehicle in the full-pull condition;
determining whether the measured ground speed is below a predetermined ground speed value;
measuring a plurality of key indicator values of the vehicle when the measured ground speed is below the predetermined ground speed value;
determining whether at least one of the measured plurality of key indicator values is outside of a predetermined specification for the corresponding key indicator value;
concluding that low measured ground speed is the result of a mechanical condition when at least one of the measured plurality of key indicator values is outside of specification; and
concluding that low measured ground speed is the result of an operational condition when none of the measured plurality of key indicator values is outside of specification.

Abstract
A method of determining a cause of a performance deficiency of a vehicle may include: Determining whether the vehicle is operating in a defined load condition; comparing an actual vehicle performance parameter with a predetermined baseline performance parameter for the defined load condition; comparing a plurality of key indicator values of the vehicle with a predetermined specification for each of the plurality of key indicator values; concluding that the performance deficiency is the result of a mechanical condition of the vehicle when at least one of the key indicator values is outside of the predetermined specification for a corresponding key indicator value and when the actual vehicle performance parameter is outside of the predetermined baseline performance parameter; and concluding that the performance deficiency is the result of an operational condition when none of the key indicator values is outside of the predetermined specification for the corresponding key indicator value and when the actual vehicle performance parameter is outside of the predetermined baseline performance parameter.

12. A method of determining a cause of a performance deficiency of a vehicle, comprising:
-
determining whether the vehicle is operating in a defined load condition; comparing an actual vehicle performance parameter with a predetermined baseline performance parameter for the defined load condition when the vehicle is operated in the defined load condition; comparing a plurality of key indicator values of the vehicle with a predetermined specification for each of said plurality of key indicator values; concluding that the performance deficiency is the result of a mechanical condition of the vehicle when at least one of the key indicator values is outside of the predetermined specification for a corresponding key indicator value and when the actual vehicle performance parameter is outside of the predetermined baseline performance parameter; and concluding that the performance deficiency is the result of an operational condition when none of the key indicator values is outside of the predetermined specification for the corresponding key indicator value and when the actual vehicle performance parameter is outside of the predetermined baseline performance parameter. - View Dependent Claims (13, 14, 15, 16, 17, 18)

19. A non-transitory computer-readable storage medium having computer-executable instructions embodied thereon that, when executed by at least one computer processor cause the processor to:
-
determine when an off-road vehicle is in a full-pull condition; determine a ground speed of the vehicle in the full-pull condition; determine whether the ground speed is below a predetermined ground speed value; receive from a vehicle sensing system a plurality of key indicator values of the vehicle when the ground speed is below the predetermined ground speed value; determine whether at least one of the received plurality of key indicator values is outside of a predetermined specification for the corresponding key indicator value; conclude that low measured ground speed is the result of a mechanical condition when at least one of the plurality of key indicator values is outside of specification; and conclude that low measured ground speed is the result of an operational condition when none of the measured plurality key indicator values is outside of specification.

20. A system for determining causes of performance deficiencies of an off-road vehicle, comprising:
-
a network; a plurality of sensors operatively associated with the off-road vehicle for sensing at least a plurality of key indicator values, said plurality of sensors being operatively associated with said network; a processing system operatively associated with said network, said processing system being configured to; determine whether the vehicle is in a full-pull condition; determine a ground speed of the vehicle in the full-pull condition; determine whether the ground speed is below a predetermined ground speed value; determine whether at least one of the plurality of key indicator values is outside of a predetermined specification for the corresponding key indicator value; conclude that low ground speed is the result of a mechanical condition when at least one of the plurality of key indicator values is outside of specification; and conclude that low ground speed is the result of an operational condition when none of the measured plurality key indicator values is outside of specification; and a display system operatively associated with said processing system, said processing system displaying on said display system at least information relating to said conclusions.
