Abstract
Systems and methods for operating a driveline disconnect clutch of a hybrid vehicle are presented. In one example, a time duration of a boost phase of a driveline disconnect clutch closing sequence is adjusted in response to one or more error values. The error values may include pressure error, integrated pressure error, and electric machine speed error.
Claims20
A method for operating a vehicle, comprising:
- via one or more controllers, adjusting a boost phase duration for a driveline disconnect clutch closing sequence in response to a plurality of errors.
A system, comprising:
- an internal combustion engine;
- an integrated starter/generator;
- a disconnect clutch positioned in a driveline between the internal combustion engine and the integrated starter/generator;
- and
- a controller including executable instructions stored in non-transitory memory that cause the controller to adjust a boost phase duration in response to a plurality of error values.
2 more elements
A method for operating a vehicle, comprising:
- via one or more controllers, adjusting a boost phase duration for a driveline disconnect clutch closing sequence in response to a sum of a plurality of weighted error values;
- and
- adjusting opening of a driveline disconnect clutch according to the adjusted boost phase duration.
