Patent ID: 7487679

Claim:
A tool for measuring and analyzing vibrations in a vehicle having an operator seat, comprising: a plurality of rotational velocity sensors configured to measure a rotational velocity of at least one driveline member; a tri-axial accelerometer configured to be coupled to said operator seat; a processing unit including a display and a processor electrically coupled to said plurality of rotational velocity sensors and to said tri-axial accelerometer; and wherein said processing unit is configured to receive acceleration signals from said tri-axial accelerometer, receive rotational velocity signals from said plurality of rotational velocity sensors, determine vehicle vibration levels from said acceleration signals and said rotational velocity signals, attribute said vehicle vibration levels to possible vibration sources, and display said possible vibration sources; wherein said processing unit is further configured to: house a list of acceptable vibration thresholds based on vibration type and amplitude; compare said vehicle vibration levels to said list of acceptable vibration thresholds; determine if one of said vehicle vibration levels exceeds one of said acceptable vibration thresholds; and if one of said vehicle vibration levels exceeds one of said acceptable vibration thresholds, display a possible remedy to reduce said threshold exceeding vehicle vibration level.
