A control device of an internal-combustion engine

Document Type and Number:

Japanese Patent JP6264325

Kind Code:

B2

Abstract:

A control device for an internal combustion engine (10) includes a knock control system, a cooling system (30; 16, 30), and an electronic control unit (44). The knock control system is configured to ignite a spark plug an ignition crank angle obtained by retarding the ignition crank angle in response to an occurrence of the knocking. The electronic control unit (44) is configured to supply a command value corresponding to a target value of a cooling parameter to the cooling system (30; 16, 30) such that the cooling system (30; 16, 30) performs cooling of the internal combustion engine (10) according to the command value. The electronic control unit (44) is configured to correct the command value based on a KCS learned value such that as the KCS learned value increases, a correction amount for correcting the command value increases in correction amount in a direction in which a cooling capacity of the cooling system (30; 16, 30) increases.
