Abstract: A vehicle includes an engine, a clutch, and a controller. The clutch is configured to crank the engine during an engine start. The controller is programmed to, in response to a command to start the engine, adjust a clutch actuator pressure to drive a disconnect clutch torque toward a desired value. The controller is further programmed to, in response to variances of the disconnect clutch torque relative to the clutch actuator pressure exceeding a threshold, issue a disconnect clutch fault.

Abstract: A method of producing a disconnect clutch includes producing a disconnect clutch, configured to selectively connect an engine and an electric machine, such that the disconnect clutch exhibits a clutch transfer function that causes a transmission output shaft torque variability that is less than a predetermined threshold during a simulated starting of the engine using the electric machine.
