Abstract:
A control apparatus of an engine comprising:a throttle valve controller capable of controlling an opening degree of a throttle valve independent from an accelerator;a target torque calculating section calculating a target engine torque using an operation amount of said accelerator;a first opening area calculating section converting said target engine torque into a first opening area of said throttle valve;an idling required air amount calculating section calculating a required air amount at the time of idling;a second opening area calculating section converting said required air amount into a second opening area of said throttle valve;a total opening area calculating section adding said first opening area of said throttle valve and said second opening area of said throttle valve to calculate a target total opening area of said throttle valve;a target opening degree calculating section calculating a target opening degree of said throttle valve in correspondence to said target total opening area; andan output section outputting said target opening degree to said throttle valve controller;wherein said second opening area calculating section converts said required air amount into said second opening area of said throttle valve in a sonic region.
