Abstract
There is provided a behavior control device for the prevention of a jackknife phenomenon of a combination vehicle including a tractor and a trailer pivotably coupled with the tractor, taking into account that the relative pivoting action of the trailer and tractor varies according to the magnitudes of a vehicle speed or a deceleration. The inventive behavior control device comprises a braking-driving force control portion which controls a braking-driving force of the tractor or the trailer to reduce a difference between a yaw rate of the tractor and a yaw rate of the trailer and a judgment portion which judges whether or not a braking-driving force control of the tractor or the trailer by the braking-driving force control portion is necessary; wherein the judgment portion changes based on a vehicle speed or a deceleration of the vehicle the judgment of whether or not the braking-driving force control is necessary.
