摘要： An engine control apparatus works to determine a target value of each of performance parameters associated with different types of performances of a combustion engine based on operating conditions of the combustion engine, determine target values of combustion parameters associated with combustion states of fuel in the combustion engine based on the target values of the performance parameters using first correlation data representing correlations between the performance parameters and the combustion parameters, and calculate command values of controlled parameters for actuators as a function of the target values of the combustion parameters. When actual values of the performance parameters are in coincidence with the target values, the system changes or corrects the target value of a selected one of the performance parameters so as to enhance the level of a corresponding one of the performances of the engine based on the other performance parameters.

摘要： An engine control system which may be used in automotive vehicles includes first correlation data representing correlations between performance parameters associated with different types of performances of a combustion engine and uncorrelated common factors existing among the performance parameters and second correlation data representing correlations between the common factors and combustion parameters associated with combustion states of fuel in the combustion engine. The engine control system determines target values of the common factors using the first correlation data and also determines target values of the combustion parameters using the second correlation data. The engine control system determines command values as a function of the target values of the combustion parameter and outputs them to actuators which control combustion states of fuel in the engine for achieving desired levels of the performances of the combustion engine. This enables the performance parameters to be controlled independently of each other without any interference.

摘要： A learning time counter is started and updated if an operation state is stabilized after shifting to a certain operation range. Then, convergence of a FCCB correction value of a variation in an injection characteristic is determined. If the FCCB correction value is determined to have converged, a permit flag is turned on and the FCCB correction value is decided as a learning value. Even if the FCCB correction value does not converge, the learning value is compulsorily decided when the learning time counter reaches a threshold. If the FCCB correction value is decided early, a surplus time is added to a threshold of the next operation range. Thus, the variation of the injection characteristics among cylinders can be learned highly accurately while averting unnecessary lengthening of a learning time.

摘要翻译：如果在转换到某个操作范围之后操作状态稳定，则启动和更新学习时间计数器。然后，确定喷射特性的变化的FCCB校正值的收敛。如果确定FCCB校正值已经收敛，则允许标志被打开，FCCB校正值被确定为学习值。即使FCCB校正值不会收敛，当学习时间计数器达到阈值时，强制地决定学习值。如果早期确定FCCB校正值，则将剩余时间添加到下一个操作范围的阈值。因此，可以高精度地学习气缸之间的喷射特性的变化，同时避免学习时间的不必要的延长。
