    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 control system includes an engine control module and a transmission control module. The transmission control module communicates with the engine control module via a network. The engine control module generates a mean engine speed signal and a minimum engine speed signal. The engine control module transmits the mean engine speed signal and the minimum engine speed signal to the transmission control module via the network. The transmission control module controls operation of at least one of a torque converter and a transmission based on the mean engine speed signal and the minimum engine speed signal. The torque converter is connected between an engine and the transmission.

    摘要: A cylinder misfire control system for a displacement on demand (DOD) engine that is operable in an activated mode and a deactivated mode includes a sensor that is responsive to rotation of a crankshaft of the engine and a first module that calculates a time derivative based on a first time period associated with a first deactivated cylinder and a second time period associated with a second deactivated cylinder. The first and second time periods are based on the rotation of the crankshaft. A second module detects a misfire occurrence in an activated cylinder based on the time period derivative.

    摘要: An engine system includes an engine, an alternator, a load, and a controller that communicates with the engine, the alternator, and the load. The controller signals the engine to drive the alternator when the engine idles. When a load increase on the engine is detected, the controller reduces an alternator load on the engine in response to the load increase. Air flow into the engine is adjusted to compensate for the load increase, and concurrently the alternator load is increased. When a load decrease is detected, the alternator load is increased, and the air flow is subsequently adjusted while decreasing the alternator load. In another embodiment, spark timing of the engine is adjusted to compensate for the load decrease.
