An apparatus for controlling a vehicle, the vehicle comprising: an internal combustion engine and at least one detecting device, the internal combustion engine comprising a plurality of cylinders and at least one intake control valve, the intake control valve being disposed in a path of intake air, the path being connected to inside of the plurality of cylinders, the intake control valve being capable of generating pulsation of the intake air in accordance with an opening / closing state and adjusting an intake air amount as an amount of the intake air, the opening / closing state being controlled in the intake control valve without seating by abutment by predetermined opening / closing control at least in a normal situation, and the intake control valve allowing inertia supercharging using the pulsation of the intake air by controlling the opening / closing state from a valve closing state to a valve opening state in a valve opening period of an intake valve, and the intake control valve being different from a throttle valve being positioned upstream there from, the detecting device being provided in a one-to-one manner together with the intake control valve, the detecting device being capable of detecting degree of opening of the intake control valve, the degree defining the opening / closing state and being referred to when the opening / closing control is performed, the apparatus having: a judging device that is configured to judge whether or not the detecting device is in a failure state; an intake air change amount detecting device that is configured to detect a change amount of the intake air amount in each of the plurality of cylinders; a limiting device that is configured to limit fluctuation of the intake air amount in a target cylinder as at least one portion of the plurality of cylinders corresponding to the detecting device which is judged to be in the failure state on the basis of the change amount detected in each of the cylinders if it is judged that the detecting device is in the failure state; a specifying device that is configured to specify a predetermined index value defined as correlating with the intake air amount in advance on the basis of the detected change amount for each of the plurality of cylinders; and a target value setting device that is configured to set a target value of the index value, the limiting device being configured to control a target intake control valve as the intake control valve corresponding to the detecting device which is judged to be in the failure state such that the specified index value converges on the set target value, depending on the magnitude relationship between the specified index value and the set target value, without using the detected degree of opening of the target intake control valve. a judging device that is configured to judge whether or not the detecting device is in a failure state; an intake air change amount detecting device that is configured to detect a change amount of the intake air amount in each of the plurality of cylinders; a limiting device that is configured to limit fluctuation of the intake air amount in a target cylinder as at least one portion of the plurality of cylinders corresponding to the detecting device which is judged to be in the failure state on the basis of the change amount detected in each of the cylinders if it is judged that the detecting device is in the failure state; a specifying device that is configured to specify a predetermined index value defined as correlating with the intake air amount in advance on the basis of the detected change amount for each of the plurality of cylinders; and a target value setting device that is configured to set a target value of the index value, the limiting device being configured to control a target intake control valve as the intake control valve corresponding to the detecting device which is judged to be in the failure state such that the specified index value converges on the set target value, depending on the magnitude relationship between the specified index value and the set target value, without using the detected degree of opening of the target intake control valve.
