Alternator controls for quick engine torque modulation

An engine torque control method for a vehicle, the engine torque control method comprising:

• providing an alternator driven by a crankshaft of an engine of the vehicle and configured to generate electrical energy;
• providing an energy storage system configured to receive at least a maximum current from the alternator while the alternator is operating at a maximum duty cycle;
• detecting, by a control system of the vehicle, a request to decrease a torque generated by the engine by a desired torque reduction;
• and
• in response to detecting the request, commanding, by the control system, the alternator to operate at a desired duty cycle based on the desired torque reduction,
• wherein the energy storage system receives and stores the electrical energy generated by the alternator while operating at the desired duty cycle.
