Being the behavior control unit

摘要

PROBLEM TO BE SOLVED: To provide a behavior control device for a vehicle capable of improving accuracy in behavior control of the vehicle and drivability.;SOLUTION: The behavior control device 1 has an ECU 2. The ECU 2 calculates a vehicle body slip angle β (step 2), calculates a target slip angle βr (step 3), calculates a target wheel speed Ws_cmd such that the vehicle body slip angle β is converged upon the target slip angle βr (step 4), sets a changeover function setting parameter VPOLE for determining a convergence speed of the vehicle body slip angle β upon the target slip angle βr according to the vehicle body slip angle β (steps 31-35), and changes the target slip angle βr according to occurrence frequency of β≥βr in a prescribed period (steps 19-21).;COPYRIGHT: (C)2008,JPO&INPIT
