Abstract
A hydraulic management system and method are provided that account for auxiliary work tool usage. The hydraulic management system automatically calculates an effective use time of a hydraulic element, such as a hydraulic fluid or hydraulic filters, by multiplying work tool usage by a desired gain factor, where the gain factor may exceed 1 for auxiliary work tools.
Claims22
A work vehicle including:
- a chassis;
- a plurality of traction devices supporting the chassis;
- a first hydraulic work tool selectively coupled to the work vehicle for movement relative to the chassis;
- a second hydraulic work tool selectively coupled to the work vehicle for movement relative to the chassis;
- and
- a hydraulic management system including a controller that determines an effective use time of at least one hydraulic element of the work vehicle, the controller increasing the effective use time at a first rate based on usage of the first hydraulic work tool and at a second rate based on usage of the second hydraulic work tool, the second rate differing from the first rate.

A work vehicle including:
- a chassis;
- a plurality of traction devices supporting the chassis;
- at least one hydraulic work tool selectively coupled to the work vehicle for movement relative to the chassis;
- and
- a hydraulic management system including:
- a controller;
- and
- a gain input that communicates a gain factor associated with the at least one hydraulic work tool to the controller, the controller multiplying usage of the at least one hydraulic work tool by the gain factor to determine an effective use time of at least one hydraulic element of the work vehicle.
5 more elements
A method of managing a hydraulic system of a work vehicle, the method including the steps of:
- receiving a gain factor associated with a hydraulic work tool;
- operating the work vehicle with the hydraulic work tool coupled to the work vehicle;
- monitoring an actual time of the operating step;
- and
- determining an effective use time of at least one hydraulic element of the work vehicle by multiplying the actual time of the operating step by the gain factor.
