1. A vehicle action control device applied to a vehicle in which an anti-dive force that is a force for displacing a front portion of a vehicle upward is generated when a braking force is applied to a front wheel, and an anti-lift force that is a force for displacing a rear portion of the vehicle downward is generated when a braking force is applied to a rear wheel, the vehicle action control device comprising:
a vehicle required braking force acquisition unit that acquires a vehicle required braking force which is a required value of a braking force applied to the vehicle; and
a roll control unit that performs a roll suppression control of suppressing a rolling motion of the vehicle by adjusting a distribution ratio of a braking force with respect to a target wheel including at least one of a rear wheel on an inside during turning of the vehicle and a front wheel on an outside during turning of the vehicle when the braking force is applied to the vehicle according to the vehicle required braking force under a situation where the vehicle is turning,
wherein execution of the roll suppression control is started when a determination is made that the vehicle is gradually turning and there is no wheel in which the slip amount is greater than or equal to the determination slip amount which is set as a determination criterion for whether a deceleration slip has occurred in the wheels,
wherein in the roll suppression control, the roll control unit sets the distribution ratio of a braking force with respect to at least one of a rear wheel on an inside during turning of the vehicle and a front wheel on an outside during turning of the vehicle higher than a distribution ratio when the roll suppression control is not performed, and
wherein the roll control unit permits execution of the roll suppression control when the vehicle turns by automatic driving, and does not permit execution of the roll suppression control when the vehicle turns by manual steering.
