Hydraulic motor having controlled output based on machine slippage model

A non-transitory computer-readable medium including computer executable instructions for managing excessive slippage at a physical interface between a machine and a traveled surface, the computer-executable instructions, when executed by a programmed controller, facilitating performing the steps of:

• determining a track force, the track force being indicative of the propulsive force exerted by the machine on the traveled surface;
• determining a modeled slippage based, at least in part, upon the track force and a slippage model;
• and
• conditionally causing a reduction of power output to propulsive drive components, by a motor, based upon a comparison between the modeled slippage and a slippage limit.

A machine including:

• a propulsive force source for driving the machine on a traveled surface;
• and
• a programmed controller including a slippage control module including computer-executable instructions for managing excessive slippage at a physical interface between a machine and a traveled surface, the computer-executable instructions, when executed by the programmed controller, facilitating performing the steps of:
• determining a track force, the track force being indicative of the propulsive force exerted by the machine on the traveled surface;
