Abstract
Systems and methods for improving operation of a hybrid vehicle are presented. In one example, compensation is provided for a dual mass flywheel positioned in a vehicle driveline. The approaches may reduce driveline torque disturbances.
Claims19
A method of adjusting operation of a hybrid vehicle driveline, comprising:
- adjusting a torque converter clutch 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 a driveline component positioned between the engine and the driveline disconnect clutch.
A method of adjusting operation of a hybrid vehicle driveline, comprising:
- engaging a driveline disconnect clutch to rotate an engine via a driveline integrated starter/generator (DISG);
- and
- adjusting the DISG in response to a speed or torque differential across a dual mass flywheel (DMF) positioned in the hybrid vehicle driveline between the engine and the driveline disconnect clutch, where the DMF is a driveline component between the engine and the driveline disconnect clutch.
A hybrid vehicle system, comprising:
- an engine;
- a dual mass flywheel (DMF) including a first side mechanically coupled to the engine;
- a driveline disconnect clutch including a first side mechanically coupled to a second side of the DMF;
- a driveline integrated starter\generator (DISG) including a first side coupled to a second side of the driveline disconnect clutch;
- and
- a controller including non-transitory instructions executable to adjust the DISG in response to a speed difference across the DMF.
3 more elements
A method of adjusting operation of a vehicle driveline, comprising:
- adjusting an actuator in response to engagement of a driveline disconnect clutch to dampen oscillation of a dual mass flywheel (DMF) positioned between an engine and the driveline disconnect clutch, and where the DMF is between the engine and the driveline disconnect clutch.
