    摘要: A method and system for controlling an engine function includes a deflection determination module generating a clutch deflection signal. The system further includes an engine function module controlling an engine function in response to the clutch deflection signal. The clutch deflection signal may be generated by sensors associated with the transmission shaft such as within the clutch housing or the friction disk.

    摘要: An engine control system includes a disturbance module, a misfire threshold determination module, a disturbance ratio module, and a spark control module. The disturbance module determines a disturbance value for a past combustion stroke of a cylinder based on rotation of a crankshaft. The misfire threshold determination module determines a jerk value indicative of a misfire within the cylinder. The disturbance ratio module determines a disturbance ratio for the past combustion stroke based on the disturbance value and the jerk value. The spark control module determines a spark timing for a future combustion stroke of the cylinder, determines a spark timing correction for the future combustion stroke based on the disturbance ratio, determines a corrected spark timing based on the spark timing and the spark timing correction, and generates spark during the future combustion stroke based on the corrected spark timing.
