Abstract
This document discloses an adaptive fan control system for controlling a fan that cools an engine of a machine. Many machines carry out repetitive tasks or work cycles. The cooling requirements of the engine vary for each portion or segment of a work cycle. The disclosed system includes a controller with a memory having a plurality of stored work cycle patterns. Using a variety of sensors, the system and controller identifies the work cycle that the machine is carrying out and, using one of the stored work cycle patterns, the system anticipates the cooling requirements of the machine as the machine progresses through the work cycle and the system proactively changes the fan speed for upcoming segments of the work cycle.
