Abstract
A drivetrain system for a machine includes an engine, a brake, and a controller operatively coupled to the engine and the brake. The controller is configured to generate a first speed error based on a first speed command signal and a first ground speed signal; generate a first engine speed command signal based on the first speed error; send the first engine speed command signal to the engine; compare the first speed error to an upper threshold; set a brake command signal to an engagement value when a magnitude of the first speed error is greater than a magnitude of the upper threshold; engage the brake in response to setting the brake command signal to the engagement value; and increase a speed of the engine in response to the first engine speed command signal while the brake command signal is set to the engagement value.
