Abstract
An electric drive system for a machine includes a transmission, and an electric drive motor coupled to a transmission input. The electric drive system also includes a plurality of sensing subsystems, each monitoring a speed of rotation and a direction of rotation of one of the electric drive motor or the transmission input. An electric drive control system in the electric drive system includes an electronic controller structured to receive health data of the sensing subsystems, and determine a drive system control command, according to a sensor data sourcing pattern that is dependent upon the health data. Related methodology and control logic is also disclosed.
