Abstract
A method of dissipating power on a propelled machine includes setting a target ground speed for the machine, and, if the throttle position is less than a first predetermined minimum and if the machine is on a negative grade in the direction of travel no greater than a second predetermined minimum, and the calculated machine resistance power is less than the calculated grade power, the method include engaging at least a portion of the energy-dissipating electrically or electrohydraulically controlled accessories to retard the machine to maintain the machine within a set range of a target speed.
