A reaction force control unit calculates a driver's requested output and then estimates a maximum output that can be generated by an engine in a current cylinder deactivation operation. Next, the reaction force control unit calculates a difference between the maximum output and the requested output as an output difference and then determines whether the output difference has reached a predetermined reaction force start threshold value, and if the determination result is Yes, the reaction force control unit estimates a number of to-be-reactivated cylinders on the basis of the output difference and the current cylinder deactivation operation state. Subsequently, the reaction force control unit sets a target reaction force on the basis of the output difference and the number of to-be-reactivated cylinders, and outputs drive current to a reaction force actuator.
