Abstract: To control turn behavior of a vehicle such as an automobile more effectively and desirably by presuming the turn behaving of the vehicle at higher precision, a turn behavior control device detects lateral acceleration Gy of a vehicle body, vehicle speed V and yaw rate r of the vehicle body, then calculates lateral slide velocity Vy of the vehicle by integrating deviation Gy-Vr according to a predetermined integration time constant, then presumes the turn behavior of the vehicle based upon at least the lateral slide velocity Vy, and then controls the turn behavior of the vehicle based upon the presumed turn behavior. When the turn behavior of the vehicle is presumed to be stable, the integration time constant is made small to decrease accumulation of errors, whereas when the turn behavior of the vehicle is presumed to be unstable, the integration time constant is made large so as to definitely execute the behavior control.
