CYLINDER COMBUSTION PERFORMANCE MONITORING AND CONTROL WITH COORDINATED TORQUE CONTROL

An engine control system includes a disturbance module, a torque correction module, a torque-to-spark module, and a spark correction module. The disturbance module determines a disturbance value for a past combustion stroke of a cylinder of an engine based on rotation of a crankshaft. The torque cor...

Zusammenfassung:An engine control system includes a disturbance module, a torque correction module, a torque-to-spark module, and a spark correction module. The disturbance module determines a disturbance value for a past combustion stroke of a cylinder of an engine based on rotation of a crankshaft. The torque correction module selectively determines a torque correction for a future combustion stroke of the cylinder based on the disturbance value. The torque-to-spark module determines a spark correction based on the torque correction and determines an uncorrected spark timing based on a torque request. The spark correction module determines a corrected spark timing based on the uncorrected spark timing and the spark correction and generates spark during the future combustion stroke based on the corrected spark timing.
