Title:
OUTPUT CONTROLLER OF INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/1990/008889
Kind Code:
A1
Abstract:
An output controller of an internal combustion engine of this invention determines a target torque of a driving shaft in an automobile based on a step-in stroke of an acceleration pedal, determines the difference between this target torque and an actual torque of the driving shaft and determines a steady output torque necessary for providing the target torque to the driving shaft by assuming that the automobile inclusive of the internal combustion engine as a whole is in a steady operating state. In the output controller, a steady intake of the internal combustion engine which provides the steady output torque to the engine is determined and corrected by a feedback quantity based on the difference described above. In this manner, a target intake of the internal combustion engine is determined and the opening of the throttle valve is controlled so as to attain this target intake.
