The apparatus includes a steering control device for controlling a relationship between a steering angle and a tire angle to be varied, and a decelerating control device for controlling a vehicle speed to be decreased. The parameter indicative of lateral margin for the tire is monitored, and the steering control device and the decelerating control device are controlled on the basis of the monitored parameter.

Abstract: In vehicle roll sensing of the present invention, a self-aligning torque (SAT) estimator estimates a composite value of SATs generated on tire contact patch of right and left wheels. A slip angle computer detects a vehicle speed and a steering angle and computes a slip angle of the wheel from the measured vehicle speed and steering angle. An SAT model value computer estimates an SAT model value as a composite value of SATs of the right and left wheels when no load shifts between the right and left wheels on the basis of the slip angle. A load shift ratio estimator estimates a load shift state of the right and left wheels on the basis of the composite value of the SATs of the wheels and the SAT model value. A vehicle rollover estimator estimates a rollover of the vehicle on the basis of the estimated load-shift state.

Abstract: In a stabilizer apparatus for a vehicle, an electronic control unit calculates a target current of an electric motor from vehicle speed, steering angle, and lateral acceleration, and increases and decreases actual current such that the calculated target current flows through the motor. The control unit decreases the actual current by a predetermined amount when the difference between the target current and the actual current becomes smaller than a predetermined value during control of increasing the actual current. The predetermined amount is equal to the difference between the determined target current at the time of the detection of the difference and current which is necessary to obtain, during control of decreasing the actual current, an output torque equal to the output torque of the speed reduction mechanism obtained as a result of the target current flowing through the electric motor.

Abstract: In accordance with a steering apparatus (20), a grip state between a ground surface on which a steered wheel is grounded and the steered wheel is estimated by a grip degree estimation arithmetically operating process (30a) which is arithmetically operated by AFS_ECU (30), and VGRS target angle is set such that a steering gear ratio is increased in the case that the grip degree gets close to a grip limit on the basis of an estimated grip state, in accordance with a grip degree vs gear ratio map (30b). Accordingly, since it is possible to estimate the grip degree which is changed in correspondence to a magnitude of the road surface it, for example, in the case that the steered wheel gets close to the grip limit, it is possible to increase the steering gear ratio so as to set large even at a time when the vehicle runs at the low speed. Therefore, since it is possible to prevent a phenomenon that the steered wheel is largely controlled by a smaller steering angle from being generated in the case that the vehicle runs on the road surface having the low μ, there is obtained an effect that a stability in the vehicle motion can be improved.
