Adaptive vibration management system for a work machine
First Claim
1. A vibration management system for a work machine, comprising:
- at least one machine component configured to respond to input commands from an operator of the work machine;
one or more vibration sensors configured to output a signal indicative of a vibration level experienced by the operator; and
a controller configured to;
monitor the output signal from one or more vibration sensors and determine an average vibration level experienced by the operator;
monitor the input commands from the operator and calculate a predicted response of the at least one machine component to at least one of the input commands;
determine a predicted vibration effect on the operator based on the predicted response; and
adjust an actual response of the at least one machine component to the at least one operator input command based on the predicted vibration effect and the average vibration level.

Abstract
A vibration management system for a work machine may include at least one machine component configured to respond to input commands from an operator of the machine. One or more vibration sensors may be configured to output a signal indicative of a vibration level experienced by the operator. A controller may be configured to monitor the output signal from the one or more vibration sensors and determine an average vibration level experienced by the operator. The controller may also be configured to monitor the input commands from the operator and calculate a predicted response of the at least one machine component to at least one of the input commands. The controller may also be configured to determine a predicted vibration effect on the operator based on the predicted response and adjust an actual response of the at least one machine component to the at least one operator input command based on the predicted vibration effect and the average vibration level.

29. A vibration management system for a work machine, comprising:
-
at least one machine component configured to respond to input commands from an operator of the machine; one or more vibration sensors configured to output a signal indicative of a vibration level experienced by the operator; at least one vibration reduction unit; and a controller configured to; monitor the output signal from the one or more vibration sensors and determine an average vibration level experienced by the operator; monitor the input commands from the operator and calculate a predicted response of the at least one machine component to at least one of the input commands; determine a predicted vibration effect on the operator based on the predicted response; and operate the at least one vibration reduction unit in a manner to at least partially counteract the predicted vibration effect on the operator when the predicted vibration effect would cause the average vibration level to exceed a predetermined vibration threshold value. - View Dependent Claims (30, 31, 32)
