Original Abstract Submitted

a vehicle behavior control apparatus includes: a variable roll stiffness device configured to change roll stiffness of a first axle being one of a front axle and a rear axle and roll stiffness of a second axle being another of the front axle and the rear axle; and a controller. the controller is configured to control the variable roll stiffness device so as to increase the roll stiffness of the first axle in accordance with a lateral acceleration in at least a low acceleration range. the controller is also configured to execute a control process of controlling the variable roll stiffness device so as to increase the roll stiffness of the second axle when the lateral acceleration increases to a high acceleration range beyond the low acceleration range, or a vehicle stability control for reducing at least one of oversteer and understeer of the vehicle is abnormal.
