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.
Claims20
A method for operating a tandem axle of a vehicle, comprising:
- adjusting operation of a first axle via a controller in response to a presence of a beat signal generated via the first axle and a second axle;
- and
- adjusting torque of a first electric machine in the first axle and adjusting torque of a second electric machine in the second axle.
A tandem axle system, comprising:
- a first axle including a first electric machine configured to provide propulsive effort via the first axle;
- a second axle including a second electric machine configured to provide propulsive effort via the second axle;
- and
- a controller including executable instructions stored in non-transitory memory that cause the controller to adjust operation of the first axle and the second axle in response to a beat signal, the beat signal generated via combining a first signal generated via the first axle and a second signal generated via the second axle.
