PROBLEM TO BE SOLVED: To provide an EGR control device capable of preventing inhibition of an actuation of an EGR device in a state that requires the actuation of the EGR device.SOLUTION: An EGR introduction line corresponding to an EGR introduction level X according to an operational state of an engine is set to a temperature map using, as a parameter, a temperature of cooling water of the engine and a temperature of air passing through an intake passage. An actuation of an EGR device is allowed or inhibited on the basis of a comparison result on the temperature map between both the temperature of the cooling water of the engine and the temperature of the air passing through the intake passage and the EGR introduction line.SELECTED DRAWING: Figure 2 |
