PROBLEM TO BE SOLVED: To provide a vehicle behavior control device capable of most suitably controlling wheel slippage and vehicle behavior in accordance with a road surfaceμ. SOLUTION: A target left and right wheel cylinder pressure differenceΔP1 * in accordance with target yaw rate deflectionΔψ'* is computed from a difference of braking force required for generation of a vehicle behavior correction moment, first target wheel cylinder pressure P1i * is computed by distributing them to current wheel cylinder pressure Pi , a target left and right slip rate differenceΔS* in accordance with the target yaw rate deflectionΔψ'* is computed from a wheel speed difference at the time of turning in a neutral steering state, a target slip rate Si* and target wheel speed Vwi * is computed by distributing them to each of the wheels, second target wheel cylinder pressure P2i * is computed by adding and subtracting second target wheel cylinder increase reduction pressure quantityΔPi * required for performance of the target wheel speed Vwi * to and from the current wheel cylinder pressure Pi , and the smaller of the two is made to follow the wheel cylinder pressure.
