Abstract
Systems and methods for operating a hybrid driveline that includes an engine, a motor/generator, and a driveline disconnect clutch are described. The systems and methods may improve vehicle efficiency while providing expected vehicle operation and performance. In one example, transmission line pressure is adjusted to match driveline disconnect clutch torque capacity to driver demand torque.
Claims20
A driveline operating method, comprising:
- receiving a driver demand torque to a controller;
- and
- adjusting a torque capacity of a driveline disconnect clutch via the controller responsive to the driver demand torque and an offset torque.
A driveline operating method, comprising:
- receiving a driver demand torque to a controller;
- and
- adjusting a torque capacity of a driveline disconnect clutch via adjusting a line pressure output from a transmission pump and the controller in response to the driver demand torque and a first offset torque.
A driveline system, comprising:
- an engine;
- an integrated starter/generator;
- a driveline disconnect clutch positioned in a driveline between the engine and the integrated starter/generator;
- a transmission including a pump;
- and
- a controller including executable instructions stored in non-transitory memory to adjust an outlet pressure of the pump in response to a driver demand torque and a first offset torque.
