Abstract: A system for control of an internal combustion system having subsystems, each with different response times. Subsystems may include a fuel system, an air handling system, and an aftertreatment system, each being operated in response to a set of reference values generated by a respective target determiner. Calibration of each subsystem may be performed independently. The fuel system is controlled at a first time constant. The air handling system is controlled on the order of a second time constant slower than the first time constant. The aftertreatment system is controlled on the order of a third time constant slower than the second time constant. A subsystem manager is optionally in operative communication with each target determiner to coordinate control. Generally, dynamic parameters from slower subsystems are treated as static parameters when determining reference values for controlling a faster subsystem.

Abstract: Methods and apparatuses for calibration and control of various engine subsystems using a target value approach. Under the target value approach, the control of each engine subsystem is separated or decoupled to include a set of target values, or a reference value set. A subsystem has a corresponding target determiner, which provides a target value set, or reference value set, in response to a basis variable set and optionally an overall subsystem target. The basis variable set includes parameters selected to robustly characterize the variables that affect the operation of the particular subsystem. The target determiner is optionally calibrated to provide a reference value set within specifications of the subsystem. A physical subsystem controller operates in response to the reference value set.

Abstract: An ECU (20), after the cranking is started, performs a control such that the first combustion cycle is executed on a CPS-equipped cylinder (step 100). After that, self-ignition occurs in the first combustion cycle, and the in-cylinder pressure changes. The ECU (20) detects change of the in-cylinder pressure by using a cylinder pressure sensor (22), and acquires the maximum value thereof as a value Pmax (step 102). Next, the acquired value Pmax is corrected on the basis of the engine coolant temperature or the amount of in-cylinder air (step 104). The ECU (20) pre-stores the relationship between the value Pmax and the octane number (RON) as a map. The ECU (20) determines the octane number (RON) that corresponds to the value Pmax, from the map (step 106).
