Egr device

An EGR device to be applied to a vehicle, the EGR device comprising:

• a valve driver configured to drive an EGR valve to open, when fuel cut has been continued for a predetermined time in a state where an engine speed of an engine of the vehicle is equal to or higher than a predetermined rotational speed;
• a pressure comparison unit configured to compare a pre-driving pressure of an intake pipe of the engine before the EGR valve is driven with a post-driving pressure of the intake pipe after the EGR valve has been driven;
• a freeze determination unit configured to set a determination flag indicating that the EGR valve is frozen when a difference between the pre-driving pressure and the post-driving pressure is less than a predetermined value and an external temperature is less than a threshold;
• and
• an EGR controller configured to, when the determination flag has been set, set a control state of the EGR valve to a closed state and stop EGR control.
