Patent ID: 7761215

Claim:
A turning behavior control device of a vehicle having front and back, left and right wheels, comprising: a control yaw moment calculator for calculating a control yaw moment to be added to a vehicle; a first yaw motion adjuster, adjusting a drive force applied to the left wheel and the right wheel in at least one of the front wheels and the rear wheels of the vehicle to adjust difference in driving force between the left and right wheels; a second yaw motion adjuster, adjusting a braking force applied to the left wheel and the right wheel in at least one of the front wheels and the rear wheels in order to adjust difference in driving force between the left and right wheels, the second yaw motion adjuster being provided independently from the first yaw motion adjuster, such that the second yaw motion adjuster adjusts the braking force independently from the drive force adjusted by the first yaw motion adjuster; and a yaw motion controller, outputting control signals to the first and second yaw motion adjustor to generate the control yaw moment, controlling the second yaw motion adjustor to increase braking force of the turning outer wheel while controlling the first yaw motion adjustor in order to increase driving force of the turning inner wheel when decelerating the yaw motion of the vehicle, and controlling the second yaw motion adjustor to increase the braking force of the turning inner wheel while controlling the first yaw motion adjustor to increase driving force of the turning outer wheel when accelerating the yaw motion of the vehicle, wherein; when accelerating the yaw motion of the vehicle, the yaw motion controller increases an amount of control distributed to the first yaw motion adjustor, such that the increase in the amount of control is larger than an increase in the amount of control distributed to the first yaw motion adjustor in the case of decelerating the yaw motion of the vehicle; and when decelerating the yaw motion of the vehicle, the yaw motion controller increases an amount of control distributed to the second yaw motion adjustor, such that the increase in the amount of control is larger than an increase in the amount of control distributed to the second yaw motion in the case of the accelerating the yaw motion of the vehicle.
