Abstract
An engine torque control method for an electrified vehicle having a series hybrid powertrain with at least two electric traction motors includes, in response to detecting an open-to-closed state transition of a drive shaft disconnect system configured to selectively connect and disconnect a first axle system or a pair of first wheels of the electrified vehicle from a first electric traction motor of the series hybrid powertrain, determining an optimum engine torque for the open-to-closed state transition based on a set of parameters for the open state of the drive shaft disconnect system, determining engine torque constraints for the open state and the closed state of the drive shaft disconnect system, applying the engine torque constraints to the optimum engine torque for the open-to-closed state transition to obtain a final engine torque command, and controlling an engine of the series hybrid powertrain based on the final engine torque command.
