Auto fluid condition alert
First Claim
1. A method for determining an optimal time to recharge hydraulic fluid in a work vehicle, the method comprising:
- making a real time determination of at least a quality parameter of the hydraulic fluid in the work vehicle, wherein the quality parameter includes particle count;
comparing, in real time, the at least a quality parameter of the hydraulic fluid with a predetermined value for the hydraulic fluid;
determining in real time, from the comparative value of the at least a quality parameter, the optimal time for a recharge of the hydraulic fluid in the work vehicle; and
alerting an operator of the work vehicle of the opportunity to recharge the hydraulic fluid in the work vehicle, wherein the alerting includes using an escalated alarm system for stepwise reduction in the work vehicle efficiency according to the degree of contamination of the hydraulic fluid.

Abstract
A method and device for determining the appropriate time to recharge hydraulic fluid in a work vehicle. The method preferably includes making a real time determination of the at least a quality parameter of hydraulic fluid in a work vehicle. The system includes comparing in real time, the quality parameter to a predetermined value for the hydraulic fluid. The method of the present invention also includes a system for comparing the determined values and communicating same to an operator. The method of the present invention also includes the capacity to control the output level of the work vehicle according to the level of contamination in the hydraulic fluid. The present invention also provides a device for real time monitoring and control of the hydraulic fluid.
