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 estimating driveline disconnect clutch torque so that driveline torque disturbances may be reduced. In one example, driveline disconnect clutch torque capacity and engine torque may be a basis for estimating driveline disconnect clutch torque.
Claims20
A vehicle system, comprising:
- an electric machine;
- an engine;
- a driveline disconnect clutch mechanically coupled to the engine and the electric machine;
- and
- one or more controllers including executable instructions stored in non-transitory memory to adjust an engine torque actuator responsive to driveline disconnect clutch torque, the driveline disconnect clutch torque based on an engine torque and driveline disconnect clutch torque capacity.
2 more elements
A vehicle operating method, comprising:
- receiving sensor input to a controller;
- adjusting a driveline torque actuator responsive to a driveline disconnect clutch torque, the driveline disconnect clutch torque based on engine torque and a driveline disconnect clutch capacity, where the engine torque is based on the sensor input.
A vehicle operating method, comprising:
- receiving sensor input to a controller;
- adjusting a driveline torque actuator responsive to a driveline disconnect clutch torque, the driveline disconnect clutch torque being responsive to operating the driveline disconnect clutch in at least one of a plurality of driveline disconnect clutch torque prediction zones.
