Abstract
Systems and methods for operating a driveline disconnect clutch of a hybrid vehicle are presented. In one example, torque capacity of a driveline disconnect is adjusted in response to a change in commanded line pressure. The torque capacity of the driveline disconnect clutch may be adjusted in according to a maximum transmission line pressure.
Claims20
A method for operating a vehicle, comprising:
- via one or more controllers, commanding an adjustment to a driveline disconnect clutch pressure for a predetermined amount of time in response to a change in transmission line pressure.
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;
- a transmission included in the driveline;
- and
- a controller including executable instructions stored in non-transitory memory that cause the controller to adjust a driveline disconnect clutch pressure command for a predetermined amount of time in response to a change in a transmission line pressure.
