Being the behavior control unit

摘要

PROBLEM TO BE SOLVED: To prevent a spin suppression effect from being reduced due to contribution of a second-order differential value of a vehicular body slip angle when abrupt steering is repeated, in a behavior controller for suppressing a spin behavior of a vehicle, using a spin state quantity calculated based on the vehicular body slip angle, a differential value thereof and the second-order differential value thereof as controlled variables.;SOLUTION: This controller reduces gradually the contribution of the second-order differential value of the vehicular body slip angle in the spin state quantity, after executing the steering in one of left and right directions of the vehicle, and after a level of the second-order differential value of the vehicular body slip exceeds a prescribed value.;COPYRIGHT: (C)2010,JPO&INPIT
