Abstract
A method for operating a vehicle that includes a driveline disconnect clutch is described. In one example, the method adjusts torque of an electric machine in response to a estimated torque capacity of the driveline disconnect clutch. The estimated torque capacity of the driveline disconnect clutch is based on a combined inertia of a dual mass flywheel and the driveline disconnect clutch.
Claims20
A vehicle operating method, comprising:
- estimating an amount of torque transferred through a driveline disconnect clutch via a combined inertia of one side of a dual mass flywheel and one side of the driveline disconnect clutch;
- and
- adjusting torque of an integrated starter/generator via a controller in response to the amount of torque transferred through the driveline disconnect clutch.
A vehicle system, comprising:
- an engine;
- a dual mass flywheel coupled to the engine and a driveline disconnect clutch;
- an electric machine coupled to the driveline disconnect clutch;
- a torque converter coupled to the electric machine and a step ratio transmission;
- a controller including executable instructions stored in non-transitory memory to estimate an amount of torque transferred through the driveline disconnect clutch via a spring torque of the dual mass flywheel and combined inertia of one side of the dual mass flywheel and one side of the driveline disconnect clutch, and additional instructions to adjust a torque of the electric machine in response to the amount of torque transferred through the driveline disconnect clutch.
