CLUTCH AND ELECTRIC MACHINE CONTROL FOR DRIVELINE DAMPING
First Claim
Patent Images
1. A method of controlling a vehicle comprising:
- in response to a torque output by an electric machine achieving a torque limit while operating to partially satisfy a demand for driveline damping and while a clutch, coupling the electric machine and wheels, is locked, slipping the clutch to completely satisfy the demand for driveline damping.

Abstract
A vehicle includes an engine, a traction motor, a clutch, and a controller. The clutch selectively couples the traction motor to wheels. The controller, in response to a torque output by the fraction motor achieving a torque limit while operating to partially satisfy a demand for driveline damping and while the clutch is locked, slips the clutch to completely satisfy the demand for driveline damping.

11. A method of controlling a vehicle comprising:
in response to an engine charging a battery configured to supply power to an electric machine while the electric machine is supplying torque to at least partially satisfy a given demand for driveline damping, reducing the torque and increasing slip of a clutch coupling the electric machine and wheels based on a torque limit of the electric machine. - View Dependent Claims (12, 13, 14, 15, 16, 17)
