    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: In accordance with a vehicle motion control apparatus, a steering angle (θh) of a steering wheel is determined on the basis of a rotation angle (θpm) of an assist motor (24m) detected by a rotation angle sensor (24s) and a rotation angle (θvm) of a gear ratio variable motor (32m) detected by a rotation angle sensor (32s), and a VGRS control process (40a) of a gear ratio variable mechanism is executed on the basis of the determined steering angle (θh). Accordingly, since the steering angle (θh) of the steering wheel is determined on the basis of the rotation angle (θvm) used for the VGRS control process (40a) of the gear ratio variable mechanism and the rotation angle (θpm) used for an EPS control process (30a) of an EPS actuator, it is possible to obtain the steering angle (θh) of the steering wheel without a steering angle sensor. Therefore, it is possible to reduce the number of the parts of a vehicle motion control apparatus.

    摘要: In a steering apparatus, in accordance with a grip limit control process (30b′), it is determined whether or not a grip degree ε estimated by a grip degree estimation arithmetically operating process (30a) is less than a predetermined grip degree (ε′), and in the case that it is determined that an estimated grip degree (ε) is less than the predetermined grip degree (ε′), the process applies such a feeling that a steering operation by a steering wheel suddenly becomes light to a driver, by suddenly increasing an assist quantity by a motor (M), thereby notifying the driver of the matter that the grip degree of a steered wheel is close to a limit. Therefore, it is possible to transmit to the driver a probability that a side slip is generated by further turning the steering wheel 21 in the same direction as the current direction, thereby calling the driver's attention for steering. Accordingly, there is an effect that a stability of a vehicle behavior can be improved without applying any fear of insecurity to the driver.
