摘要： If an actual lateral acceleration is equal to or greater than a target lateral acceleration Gth and at least one of a steering angle lateral acceleration Gys and a yaw-rate lateral acceleration Gyy is less than the target lateral acceleration Gth, the increase of the W/C pressure of the vehicle to be controlled is inhibited. Accordingly, it is possible to suppress the increase in the roll angle by actively generating the understeering to suppress rolling and to early suppress an increase in understeering if the increase in understeering is made to be unnecessary.

摘要： The present invention is directed to a vehicle motion control apparatus, which includes a hydraulic pressure regulating device disposed between a master cylinder and a pair of wheel brake cylinders included in each of a dual hydraulic circuit, and a monitor for monitoring state variable of the vehicle. It is determined whether a wheel out of the wheels operatively associated with the pair of wheel brake cylinders is located on the inside of a curve along which the vehicle is turning, or located on the outside of the curve. Also, a state of road holding of the wheel located on the inside of the curve is determined. A desired value for the wheel located on the outside of the curve is set at least on the basis of the road holding determination. And, the pressure regulating device is controlled in response to a result of comparison between the desired value and the monitored state variable, to regulate the hydraulic braking pressure in the wheel brake cylinder operatively associated with the wheel located on the outside of the curve, whereby the vehicle is decelerated smoothly, when the wheel located on the inside of the curve has come to be apart from the road.

摘要： A braking force distribution control device for an automotive vehicle is designed to make it possible to initiate a braking force distribution control as rapidly as possible upon rapid braking operation while at the same time being capable of preventing a malfunction of the braking force distribution control even when one of hydraulic pressure lines fails. The braking force distribution control establishes a predetermined relationship between the wheel cylinder pressure of a front wheel and a wheel cylinder pressure of a rear wheel on the basis of a comparison between the wheel speeds of the front and rear wheels. The braking force distribution control is initiated when the decelerations of all the wheels exceed a set value.

摘要： The present invention is directed to a system for detecting a difference in level on a road, wherein an acceleration sensor is provided for detecting an acceleration of a vehicle, and a wheel speed sensor is provided for detecting a wheel speed of at least one wheel of the vehicle. A wheel acceleration is calculated continuously on the basis of the wheel speed detected by the wheel speed sensor. It is determined if a variation of the signal output from the acceleration sensor is greater than a predetermined range. And, it is determined if the calculated wheel acceleration varied in the same direction as that of the variation of the signal output from the acceleration sensor, and then varied in the reverse direction to exceed a predetermined reference value. On the basis of the result of each determination, it is determined if the wheel ran over the difference in level on the road. If the affirmative result is obtained in each determination, the difference in level on the road can be detected.
