摘要： An engine controller diagnostic system includes a cylinder identification (ID) comparison module and a synchronization diagnostic module. The cylinder ID comparison module compares a first cylinder ID associated with a first controller with a second cylinder ID associated with a second controller. The synchronization diagnostic module determines a synchronization status of the first controller based on a comparison between the first cylinder ID and the second cylinder ID.

摘要： A system for a vehicle includes a time stamping module, a period determination module, a stochastic pre-ignition (SPI) indication module, and an SPI remediation module. The time stamping module generates first and second timestamps when a crankshaft of an engine is in first and second crankshaft positions during an engine cycle, respectively. The period determination module determines a period between the first and second timestamps. The SPI indication module selectively indicates that an SPI event occurred within a cylinder of the engine based on the period. The SPI remediation module selectively adjusts at least one engine operating parameter in response to the SPI indication module indicating that the SPI event occurred within the cylinder.

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.

摘要： A system for an engine includes first, second, third, and fourth modules. The first module determines an expected response of crankshaft speed due to combustion within a cylinder of the engine. The second module determines a value based on the expected response and a measured response of crankshaft speed due to combustion within the cylinder of the engine. The third module estimates an indicated mean effective pressure (IMEP) for the cylinder of the engine based on the value. The fourth module selectively adjusts an operating parameter of the engine based in the estimated IMEP.

摘要： An engine torque control module comprises a derivative module and a cylinder torque module. The derivative module determines a derivative term for a first cylinder of an internal combustion engine based on rotation of a crankshaft and determines an average derivative term for the first cylinder based upon the derivative term. The cylinder torque module determines an operating condition of the first cylinder based on the average derivative term, adjusts a torque output of the first cylinder based on the operating condition, and adjusts a torque output of a second cylinder based on the operating condition.
