Abstract:
A vehicle is disclosed having a motor and engine selectively coupled to the motor via a clutch. The vehicle includes a controller configured to, in response to a vehicle wheel torque reversal, open the clutch to disconnect the engine from the motor, command the engine to enter a speed control mode, and control a motor output torque through a region surrounding the vehicle wheel torque reversal to reduce torque disturbances in a vehicle driveline.
