TURNING BEHAVIOR CONTROL DEVICE AND METHOD

PROBLEM TO BE SOLVED: To stabilize a turning behavior while preventing the deeri of turning performance. SOLUTION: A difference E1 is calculated (step S1). When the difference E1 exceeds a first prescribed value th1 (a determination of step S3 is "YES"), an estimation value γe at a point of the time is set as a target value γ* (step S4). A difference E2 is calculated (step S6). When the difference E2 is larger than a second prescribed value th2 (a determination of step S7 is "YES"), correction amount Δθ of a turning angle θw is calculated according to the difference E2 (step S8), and counter steering is performed according to the correction amount Δθ. Subsequently, when the difference E2 becomes smaller than the second prescribed value th2 and the difference E1 becomes smaller than the first prescribed value th1 (a determination of the step S10 is "YES"), the calculation of the correction amount Δθ and the counter steering are finished.
