Abstract:
1. A vehicle comprising: an engine; a traction motor connected to the engine by an upstream clutch; a driveline connected to a vehicle wheel, the driveline connected to the traction motor by a downstream clutch; and a controller configured to control traction motor torque through a region surrounding vehicle wheel torque reversal, control driveline input torque during torque reversal of driveline output torque to limit rate of change of driveline output torque, and control traction motor torque during a torque reversal of at least one driveline component to limit rate of change of the torque applied to the driveline component when at least one of the upstream and downstream clutches are locked, the region defined as a function of driveline input torque, driveline output torque, nonproportional driveline losses, and an actual torque ratio across the driveline.
