Abstract
Systems and methods for operating a hybrid powertrain that includes an engine and a motor/generator are described. The systems and methods provide a way of prepositioning an engine to improve a range of driveline disconnect clutch transfer function adaptation. In one example, an engine is positioned at a location where its torque to turn exceeds a threshold torque.
Claims19
A vehicle operating method, comprising:
- requesting adjustment of an application force to clutch torque capacity relationship via a controller;
- adjusting a stopping position of an engine via the controller in response to the request;
- and
- adjusting the application force to clutch torque capacity relationship via the controller.
1 more element
A vehicle operating method, comprising:
- requesting adjustment of an application force to clutch torque capacity relationship via a controller;
- adjusting a fuel pump spill control valve in response to the request via the controller;
- and
- adjusting the application force to clutch torque capacity relationship via the controller.
1 more element
A vehicle system, comprising:
- an electric machine;
- an engine including a mechanically driven fuel pump;
- a driveline disconnect clutch mechanically coupled to the engine and the electric machine;
- a belt integrated starter/generator coupled to the engine;
- and
- a controller including executable instructions stored in non-transitory memory that cause the controller to request to adjust a relationship between clutch application force and clutch torque capacity, and to adjust the engine to a stop position that is based on a position of the fuel pump in response to the request to adjust the relationship between clutch application force and clutch torque capacity of the driveline disconnect clutch.
