Abstract
Systems and methods for improving operation of a hybrid vehicle are presented. In one example, operation of a driveline disconnect clutch is adjusted to compensate for clutch wear and manufacturing tolerances.
Claims20
A method of operating a hybrid vehicle driveline, comprising:
- adjusting torque output of a driveline integrated starter/generator (DISG) in response to a difference between a desired driveline torque and an actual driveline torque during at least partially closing a driveline disconnect clutch.
A method of operating a hybrid vehicle driveline, comprising:
- adjusting torque output of a driveline integrated starter/generator (DISG) in response to a difference between a desired driveline torque and an actual driveline torque during at least partially closing a driveline disconnect clutch;
- and
- adjusting a driveline disconnect clutch transfer function based on the difference between the desired driveline torque and the actual driveline torque.
A hybrid vehicle driveline system, comprising:
- a driveline torque sensor;
- a driveline integrated starter/generator (DISG);
- an engine;
- a driveline disconnect clutch positioned in a driveline between the engine and the DISG;
- and
- a controller including executable non-transitory instructions for adjusting DISG torque output in response to a difference between a desired driveline torque and an output of the driveline torque sensor during application of the driveline disconnect clutch.
