ABSTRACT:
A method is provided for dissipating power in a propelled machine having an electric drive system and a mechanical brake system. An inclination of the machine is determined. A speed of the machine is determined. A retarding requirement is determined based on the determined inclination and speed. A first portion of the retarding requirement is allocated to be met by the electric drive system, the first portion being less than or equal to a retarding capacity of the electric drive system. A second portion of the retarding requirement is allocated to be met by the mechanical brake system if the retarding requirement is greater than the retarding capacity of the electric drive system.
