ABSTRACT:
A spin suppress control device of a vehicle makes a first spin state estimation of the vehicle body and a second spin state estimation of the vehicle body in close time proximity to the first spin state estimation, and applies a braking force to one of the front left and right wheels at the outside of the turn such that a first braking force is applied according to the first spin state estimation and a second braking force is applied according to the second spin state estimation to be at least either stronger than the first braking force or with a greater advancement relative to an actual spin state of the vehicle than the first braking force. The second spin state estimation may be executed by a reversal of yaw rate of the vehicle body across its neutral, or by a spin state above a predetermined level occurring before a predetermined time lapses from the end of the spin suppress control according to the first spin state estimation, or by a spin state estimating parameter being modified to incorporate a time-based differential thereof.
