    摘要： A vehicle motion control apparatus is provided for performing a vehicle stability control on the basis of a parameter indicative of lateral margin for a tire on a road. 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. The steering control device is controlled to decrease the tire angle relative to the steering angle, when the parameter is decreased from a value of relatively large lateral margin to a value of relatively small lateral margin, which is smaller than a first threshold value, and the decelerating control device is controlled to decrease the vehicle speed in addition to the steering control by the steering control device, when the parameter is further decreased to a value of lateral margin smaller than a second threshold value, which is smaller than the first threshold value.

    摘要： 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.

    摘要： A steering control apparatus obtains a steered amount by which a steered wheel is steered based on a left-and-right braking force difference control amount, a vehicle state control amount, and a steering control amount. The apparatus changes the magnitude of the braking force difference control amount and the magnitude of the vehicle state control amount according to a vehicle speed or to time elapsed from when braking started to be applied to the left and right wheels. Accordingly, the vehicle driving on a μ-split road is prevented from being deflected toward a side of higher friction coefficient due to the left-and-right braking force difference when the braking is applied.

    摘要： A steering control apparatus is provided for controlling a steered wheel angle of a wheel to be steered. On the basis of a road coefficient of friction estimated between right and left wheels, a braking force difference between the right and left wheels is calculated. A slip angle—total lateral force characteristic indicative of a relationship between a slip angle and a total lateral force of a wheel to be steered is provided on the basis of the estimated coefficient of friction. Then, a steered wheel angle of the wheel to be steered is set on the basis of the braking force difference and the slip angle—total lateral force characteristic.

    摘要： A vehicle motion control apparatus is provided with an anti-skid control device and a steering angle adjusting device, which adjusts the steering angle of at least one of the front and rear wheels to cancel a yaw deviation between a desired yaw factor and an actual yaw factor, to be substantially zero. An incompatibility between the devices is determined on the basis of a state of the wheel adjusted by the steering angle adjusting device to cancel the yaw deviation. And, a predetermined parameter provided between a vehicle stability directive parameter and a brake directive parameter is set on the basis of the incompatibility. Then, the anti-skid control device controls the braking force applied to each wheel of the vehicle on the basis of the predetermined parameter. Consequently, the anti-skid control giving importance to the braking force can be performed, as long as the steering angle adjusting device is operative.
