Hydraulic motor having controlled output based on machine slippage model
First Claim
1. A method of managing excessive slippage at a physical interface between a machine and a traveled surface, the method comprising:
- determining a track force, the track force being indicative of a 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 drive components, by a motor, based upon a comparison between the modeled slippage and a slippage limit.

Abstract
A method of managing operation of a machine is described herein. The machine includes drive components that supply a propulsive force exerted by the machine on a traveled surface. The machine includes a programmed controller that controls power output by a motor to the drive components of the machine, in accordance with a slippage model, to actively manage excessive slippage at a physical interface between the machine and the traveled surface. The programmed controller determines a track force indicative of the propulsive force exerted by the machine on the traveled surface. The programmed controller further determines a modeled slippage based, at least in part, upon the track force and the slippage model. The machine conditionally causes a reduction of the power output by the motor based upon a comparison, by the programmed controller, between the modeled slippage and a slippage limit.
