1. A control device of a vehicle, the vehicle including:
an engine having an exhaust system provided with a combustion chamber and a catalyst, and configured to generate a driving force to operate drive wheels of the vehicle;
a motor able to operate the drive wheels; and
a battery configured to supply driving power to the motor in a motor assist operation in which the motor operates the drive wheels, and to be charged in a regenerative operation in which the motor generates power,
the control device comprising a controller configured to control operation of the vehicle,
wherein, when the vehicle decelerates, the controller performs:
a first control in which an engine resistance is increased to obtain a higher deceleration than a requested deceleration and the motor assist operation is performed according to an increase of the engine resistance, when a state of charge (SOC) of the battery is a first given value or above; and
a second control in which a combustion state of the engine is controlled to raise a temperature of the catalyst, and the regenerative operation is performed, when the SOC of the battery is a second given value that is below the first given value.
