Abstract:
1. A roll-over suppressing control apparatus for a vehicle, comprising: a braking mechanism that brakes left and right wheels of said vehicle separately from each other; roll parameter value detection means for detecting a parameter value corresponding to a rolling state of said vehicle; turning type decision means for determining whether a turning mode of said vehicle is in a one-directional turning mode where said vehicle turns only in one direction or a steering back turning mode where a steering wheel of said vehicle is rotated in multiple directions to change the direction of turning of the vehicle; and roll-over suppressing control means for controlling said braking mechanism to apply braking force only to left or right turning outer wheels, which are the wheels positioned on the outer radius of the vehicle making a turn, when the rolling state of the vehicle upon turning of the vehicle becomes greater than a first reference state, wherein an amount of braking force applied to only the left or right turning outer wheels depends upon a magnitude of the parameter value detected by said roll parameter value detection means and the turning mode of said vehicle determined by said turning type decision means, wherein said turning type decision means decides that the vehicle is in the steering back turning mode if a steering wheel angular velocity is equal to or greater than an angular velocity set in advance in the opposite direction to the turning direction, and wherein said turning type decision means decides that the vehicle is in the one-directional turning mode if the steering wheel angular velocity is lesser than the angular velocity set in advance.
