CONTROL DEVICE AND CONTROL METHOD FOR VEHICLE

An air amount control valve of a vehicle changes an intake air amount drawn into a cylinder. A fuel cutoff process stops fuel injection from a fuel injection valve when stopping combustion in the cylinder in a case in which a crankshaft is rotating. When execution of the fuel cutoff process is requested, a temperature-increase limiting process is executed to draw fresh air into a catalyst by increasing the intake air amount through control of the air amount control valve. In a case in which an anomaly occurs in driving of the air amount control valve when executing the temperature-increase limiting process, an amount of air drawn into the catalyst is increased by increasing an engine speed.
