Abstract: PROBLEM TO BE SOLVED: To properly control a vehicle's traveling motion regardless of the operating condition of a roll rigidity changing apparatus by computing a desired yaw rate to an appropriate value while taking the operating condition of the roll rigidity changing apparatus into consideration. SOLUTION: This vehicle traveling motion controller controls a front wheel side active stabilizer device 16 and a rear wheel side active stabilizer device 18 based on desired anti-roll moment Mat and the desired front-to-rear-wheel distribution ratio Rfr of roll rigidity (S80, 100-130). A stability factor Kh is computed in such a way that the stability factor gets higher as the desired roll rigidity distribution ratio Rfr of the front wheels to the rear wheels gets higher (S230). A desired yaw rate γt is computed based on the stability factor Kh, whereby the desired yaw rate γt is computed in such a manner to become smaller as the distribution ratio of roll rigidity to the rear wheels becomes higher (S310). The controlling driving force on each wheel is controlled so that the vehicle's yaw rate γ becomes equal to the desired yaw rate γt, whereby the vehicle's traveling motion is controlled (S320-340).
