Abstract: The invention provides a roll-over suppressing control apparatus for a vehicle which can make a decision of a start of roll suppressing control appropriately in response to the degree of the possibility of turning over on its side of the vehicle. The roll-over suppressing control apparatus includes a braking mechanism for braking wheels of the vehicle, a roll rate sensor for detecting a roll rate of the vehicle, and a roll-over suppressing control section for controlling the braking mechanism so that, if the roll rate detected upon turning of the vehicle becomes equal to or higher than a control starting threshold value, then it is decided that the vehicle is in an excessively rolling state and braking force is applied to the wheels. The control starting threshold value is set to different values depending upon different types of turning of the vehicle (depending upon whether the turning is sudden steering back turning, moderate steering back turning or one-directional turning).

Abstract: An apparatus for controlling the turning behavior of a vehicle controls the braking forces of diagonally located wheels of the vehicle independently of depression of a brake pedal to produce a target braking force difference between the controlled wheels when the vehicle is turning, thereby applying a desired yaw moment to the vehicle. The braking forces of the controlled wheels are determined taking account of actual braking forces of respective non-controlled wheels which are located on the other, right or left side of the corresponding controlled wheels.

Abstract: An automatic deceleration control apparatus for a vehicle operates so as to secure appropriate tire grip performance, depending on the conditions of a road surface on which the vehicle runs turning, and restrain excessive rolling of the vehicle body, thereby stabilizing the turning behavior of the vehicle at all times. While the vehicle is turning on a high-friction road surface without undergoing yaw moment control, a safe vehicle speed is computed within the rollover limit of the vehicle. While the vehicle is turning on a low-friction road surface under yaw moment control, on the other hand, a safe vehicle speed that ensures satisfactory tire grip performance is computed in accordance with an estimated road friction coefficient. When the vehicle is about to exceed its safe speed as it turns, it is automatically decelerated to the safe speed or below. Thus, the vehicle can be prevented from spinning, drifting out, or rolling over.
