METHODS AND SYSTEMS FOR A DRIVELINE DUAL MASS FLYWHEEL
First Claim
Patent Images
1. A method of adjusting operation of a hybrid vehicle driveline, comprising:
- adjusting an actuator in response to a speed or torque differential across a dual mass flywheel (DMF) positioned in the hybrid vehicle driveline between an engine and a driveline disconnect clutch where the DMF is driveline component positioned between the engine and the driveline disconnect clutch.
