Abstract
A power management system for a forestry machine includes a controller, a cutting tool, a cutting tool positioning system, a propulsion system, and a steering system. The power management system also includes an engine control module for calculating engine load. Based upon the calculated engine load, the controller automatically adjusts at least one of cutting tool speed, cutting tool positioning system power, and steering system power and adjusts the cutting tool speed toward a speed range defined by a first predetermined percentage above a standard set speed and a second predetermined percentage below the standard set speed.
Claims19
A power management system for a forestry machine comprising:
- a controller;
- a cutting tool;
- a cutting tool positioning system;
- a propulsion system;
- a steering system;
- and
- an engine control module for calculating engine load;
- wherein, the controller compares the calculated engine load to a maximum engine power value and, if the calculated engine load exceeds the maximum engine power value, the controller automatically reduces at least one of cutting tool speed, cutting tool positioning system power, and steering system power and adjusts the cutting tool speed toward a speed range defined by a first predetermined percentage above a standard set speed and a second predetermined percentage below the standard set speed;
- wherein, the maximum engine power value is the maximum power output of the engine.
