1. An oscillation control system of a vehicle, comprising:
a distribution control module configured to determine:
a first front torque request for one or more front electric motors of the vehicle; and
a first rear torque request for one or more rear electric motors of the vehicle;
a first control module configured to:
determine a second front torque request for the one or more front electric motors of the vehicle based on the first front torque request and a front wheel road profile; and
control power flow to the one or more front electric motors based on the second front torque request;
a second control module configured to:
determine a second rear torque request for the one or more rear electric motors of the vehicle based on the first rear torque request and a rear wheel road profile; and
control power flow to the one or more rear electric motors based on the second rear torque request.
