PROBLEM TO BE SOLVED: To prevent hunting of wheel generative force change control and roll rigidity control when controlling the front-rear wheel roll rigidity distribution ratio in accordance with the degree of margin of lateral force generated in the front wheels and rear wheels. SOLUTION: A roll rigidity control device of a vehicle calculates longitudinal force Fxai of the respective wheels after subtracted correction by variation Fxdyci in longitudinal force by behavior control and variation Fxdvci in longitudinal force by distribution control of driving force from longitudinal force Fxi of the respective wheels, and lateral force Fyai of the respective wheels after subtracted correction by variation Fystci in lateral force by turning angle control from lateral force Fyi of the respective wheels (S22 to 32), and calculates a maximum lateral force Fymaxi capable of being generated in the respective wheels (S26 and S34). Also, this roll rigidity control device calculates degrees Af and Ar of margin of lateral force respectively generated in the front and rear wheels based on the lateral force Fyai and the maximum lateral force Fymaxi (S36 and S38), and controls active stabilizer devices 16 and 18 so as to reduce a difference between the degrees Af and Ar of margin (S90 and S100).
