Abstract
Systems and methods for improving operation of a hybrid vehicle are presented. In one example, a transfer function of a driveline disconnect clutch is adapted.
Claims20
A driveline disconnect clutch adaptation method, comprising:
- adjusting application force of a driveline disconnect clutch in a vehicle driveline in response to a torque sensor.
A driveline disconnect clutch adaptation method, comprising:
- rotating a torque converter impeller at a speed less than a speed based on a maximum desired torque at a torque converter turbine, the torque converter impeller in a vehicle driveline;
- and
- adjusting application force of a driveline disconnect clutch in the vehicle driveline in response to a torque sensor while an engine in the vehicle driveline is not combusting air and fuel.
A vehicle system, comprising:
- an engine;
- a dual mass flywheel including a first side mechanically coupled to the engine;
- a driveline disconnect clutch mechanically including a first side coupled to a second side of the dual mass flywheel;
- a driveline integrated starter/generator (DISG) including a first side coupled to a second side of the driveline disconnect clutch;
- a transmission selectively coupled to the engine via the driveline disconnect clutch;
- and
- a controller including executable instructions stored in non-transitory memory to adjust an estimate of torque transferred through the driveline disconnect clutch in response to a torque sensor output.
