Crowd force control in electrically propelled machine

摘要

A method of operating an electrically propelled machine includes the steps of, operating an electrical power source for the machine, and limiting an output torque of an electrical propulsion motor system of the machine based upon the occurrence of a crowd force condition of the machine. An electrically propelled machine is further provided, including an electronic controller having means for limiting motor output torque based at least in part on a crowd force condition of the machine.
