Abstract:
Method and systems are provided for adjusting an engine torque in response to changes in a desired engine torque. In one example, a method may comprise responsive to increasing desired engine torques, monotonically decreasing an alternator torque to a first level from a second level when not injecting fuel to engine cylinders, and stepping up the alternator torque from the first level to the second level while initiating engine combustion, and then monotonically decreasing the alternator torque from the second level to the first level in response to the alternator torque reaching the first level. In this way, a method may comprise adjusting a load exerted on an engine by an alternator mechanically coupled to said engine during both cylinder combustion, and during non-fueling conditions.

Claim (Index 20):
A vehicle system comprising:\n an engine with one or more cylinders; an alternator mechanically coupled to the engine; a first battery electrically coupled to a starting system for starting the vehicle system and turning on the engine, and selectively electrically coupled to one or more of the alternator and various electrical loads; a second battery electrically coupled to the alternator and the electrical loads; a voltage regulator configured to maintain a voltage and/or current supplied to a field coil of the alternator to a set point; and a controller with computer readable instructions for adjusting the voltage and/or current supplied to the field coil between a first level and a second level based on engine operating conditions, where the adjusting comprises: when not injecting fuel to the one or more engine cylinders, monotonically decreasing the voltage and/or current supplied to the field coil with increasing engine torque demand, and in response to a desired engine torque reaching a first threshold, stepping up the current and/or voltage supplied to the field coil from the first level to the second level; when injecting fuel to the one or more engine cylinders, monotonically decreasing an alternator torque with increasing engine torque demand from the first threshold to a second threshold; and maintaining the current and/or voltage supplied to the field coil at the first level in response to the engine torque demand increasing above the second threshold.
