Classification: CPC B | IPC B

Claim 0:
1. A vehicle roll control apparatus, comprising:
an active suspension having an actuator provided for a first axle of a vehicle and configured to vary roll stiffness of the first axle;
an active stabilizer having an actuator provided for a second axle of the vehicle and configured to vary roll stiffness of the second axle, the active stabilizer has a control amount that is lower than a control amount of the active suspension; and
a processor configured to control the active suspension and the active stabilizer,
the processor is configured to:
increase a control amount of the active suspension so as to increase the roll stiffness of the first axle while increasing a control amount of the active stabilizer so as to increase the roll stiffness of the second axle in accordance with an increase in a lateral acceleration acting on the vehicle, and
decrease a gain of the control amount of the active suspension with respect to the lateral acceleration in accordance with the increase in the lateral acceleration when the lateral acceleration increases to a high acceleration range beyond a low acceleration range so that a roll stiffness distribution ratio of the first axle does not exceed a predetermined value when the lateral acceleration increases to the high acceleration range beyond the low acceleration range.
