BEHAVIOR CONTROL DEVICE FOR VEHICLE

摘要

PROBLEM TO BE SOLVED: To positively and effectively prevent the spin of a vehicle caused by tack-in. SOLUTION: A spin state quantity SS is computed (S20-40), a drift-out state quantity DS is computed (S50-70), the target slip factor of a control wheel is computed on the basis of the spin state quantity SS (S120), the target slip factor of the control wheel is computed on the basis of the drift-out state quantity DS (S140), and the braking force of each wheel is controlled on the basis of these target slip factors to suppress-control spin or drift-out (S150-200). Whether there is the possibility of a vehicle being put in a tack-in state is discriminated (S80-110), and when there is the possibility of the vehicle being put in the tack-in state, the threshold value for judging whether to execute spin suppressing control is lowered (S130).
