The ECU of the stabilizer control apparatus determines, based on a high frequency component of a wheel acceleration and a low frequency component of a wheel speed difference, whether a road surface state is a rough road state or a smooth road state. When the road surface state is determined to be the rough road state, the ECU sets a turning determination threshold to a rough road threshold. When the road surface state is determined to be the smooth road state, the ECU sets the threshold to a smooth road threshold. When a turning determination parameter is greater than the threshold, the ECU sets each of first, second, and third cylinders to a lock state to increase rigidity of stabilizers. When the turning determination parameter is smaller than the turning determination threshold, the ECU sets each of the cylinders to a free state to decrease the rigidity of the stabilizers.
