    Abstract: A control system for an internal combustion engine, which is capable of quickly and properly ensuring excellent fuel economy of the engine even when atmospheric pressure has changed. The control system includes an ECU. The ECU performs weighted average calculation on lowland map values and highland map values, based on atmospheric pressure, to thereby calculate map values of a demanded torque that minimize a fuel consumption ratio of the engine in the atmospheric pressure, and calculates engine demanded output. The ECU calculates demanded torque and demanded engine speed using the map values and the engine demanded output, respectively. The ECU controls the engine using the demanded torque.

  • Patent number: 9284897
    Abstract: An intake control system for an internal combustion engine, which, even when there are a plurality of intake air amounts for attaining one target torque, is capable of positively selecting a minimum intake air amount therefrom without causing hunting, and setting the minimum intake air amount as a target intake air amount, thereby making it possible to improve fuel economy. The intake control system calculates a maximum intake air amount, sets a plurality of provisional intake air amounts within a range of 0 to the maximum intake air amount, calculates torques estimated to be output from the engine with respect to the provisional intake air amounts, respectively, selects a minimum provisional intake air amount that makes the estimated torque equal to or close to the target torque from the relationship between the provisional intake air amounts and the estimated torques, and sets the same as the target intake air amount.
