DEVICE AND METHOD FOR CONTROLLING VEHICLE

An engine ECU executes a program including: a step (S104) of estimating the occluded amount of NOx if an engine is self-rotating (YES in S100) and a catalyst temperature is equal to or higher than a predetermined temperature Ta(0) (YES in S102); and a step (S108) of performing NOx reduction treatment if the estimated occluded amount of NOx is equal to or more than a predetermined amount (YES in S106).
