Patent ID: 7975670

Claim:
A control unit for a torque-demand-type internal combustion engine, comprising: a learning control unit that executes learning of a flow characteristic of a throttle valve, which adjusts an amount of air taken in the internal combustion engine, when a state of the internal combustion engine satisfies a predetermined ISC learning control start condition; and a control unit that executes a torque-demand control using a relationship established among at least an intake efficiency of the internal combustion engine, a torque output from the internal combustion engine and an engine speed, wherein the control unit includes an intake efficiency control unit that changes the intake efficiency of the internal combustion engine so as to change an opening amount of the throttle valve while the flow characteristic of the throttle valve is being learned, and an ignition timing control unit that changes an ignition timing of the internal combustion engine when the intake efficiency of the internal combustion engine is being changed, thereby controlling the ignition timing of the internal combustion engine so that the engine speed is kept unchanged.
