Abstract
A new system architecture of the engine control system for spark ignition engines is described, based on engine torque as the central reference value.
In contrast to previous developments, this structure is not limited to the introduction of torque values at the interface of larger subsystems in a sense of rescaling of conventional interfaces. It rather represents a consequent new design in respect to the calculation of the torque, influencing control signals of the engine.
This means that there are significant advantages in regard to managing the total complexity, as well as decoupling, and the associated simplification of each calibration step, i.e., the calibration of the various characteristic values.
