  "textContent": "Provided is a control device for an internal combustion engine that includes an EGR device equipped with an EGR cooler bypass passage and a flow-rate-ratio control valve equipped with a valve disc and capable of controlling a flow rate ratio. The control device is configured, when an opening degree control execution condition is met, to execute a vibration reduction control for controlling the flow-rate-ratio control valve such that the opening degree of the valve disc becomes greater than or equal to a vibration reduction opening degree that is greater than a minimum opening degree within an opening degree control range of the valve disc. The opening degree control execution condition includes a requirement that a parameter (pulsation level value) that becomes greater when exhaust pulsation acting on the valve disc is greater is equal to or greater than a first threshold value.",
