Title:
INTERNAL COMBUSTION ENGINE CONTROL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/021721
Kind Code:
A1
Abstract:
This internal combustion engine control system is provided with: a control calculation device (20) that is a calculation device performing calculation by use of a control storage area (20m) and that, in accordance with a user request torque which is requested by a user and is a driving torque of an internal combustion engine, calculates a target control amount which is a target value of a control amount for controlling the combustion state of the internal combustion engine; and a monitoring calculation device (30) that is a calculation device performing calculation by use of a monitoring storage area (30m) different from the control storage area and that monitors whether or not an estimation torque, which is an estimation value of the actual torque of the internal combustion engine, is in a torque abnormality state of being deviated by greater than or equal to a predetermined value from engine demand torque demanded by the internal combustion engine. The monitoring calculation device has an engine demand torque calculation unit (32) that calculates the engine demand torque and an estimation torque calculation unit (33) that calculates the estimation torque. The engine demand torque calculation unit calculates, as a reserve torque, a decreased amount of the actual torque caused in association with a retard angle in ignition time of the internal combustion engine, and calculates the engine demand torque on the basis of the user request torque and the calculated reserve torque.
