Abstract
A system for controlling torque in a vehicle includes first and second propulsion systems, the first propulsion system including a combustion engine configured to drive a primary axle, the second propulsion system including an electric motor configured to drive a secondary axle, where the first propulsion system and the primary axle are mechanically independent from the second propulsion system and the secondary axle. A controller is configured to perform a method that includes estimating a first amount of torque applied to the primary axle in response to a primary axle torque request, determining a difference between the first amount of torque applied to the primary axle and the primary axle torque request, and based on the difference exceeding a selected threshold, calculating a dynamic fill torque and applying a second amount of torque to the secondary axle via the electric motor according to the calculated dynamic fill torque.
