Abstract
Methods and systems for operating a tandem axle that includes two electric machine propulsion sources are described. In one example, a controller determines a presence or absence of a beat signal that may be generated via rotating components of the tandem axle. Operation of the tandem axle may be adjusted in response to detection of the beat signal.
