摘要： A vehicle motion control system which generates a minimized switching noise when a hydraulic pressure control valve is switched. The vehicle motion control system includes an automatic hydraulic pressure generator generating a hydraulic pressure irrespective of a brake pedal operation and a hydraulic pressure control valve adjusting the hydraulic brake pressure by opening or blocking a connection between the automatic hydraulic pressure generator and a wheel brake cylinder, and performs a motion control by controlling at least the hydraulic pressure control valve in accordance with the motion of a vehicle. The vehicle motion control system has a hydraulic pressure sensor detecting a generated hydraulic pressure of the automatic hydraulic pressure generator, setting a necessary hydraulic pressure for control, and adjusting the generated hydraulic pressure of the automatic hydraulic pressure generator by controlling the automatic hydraulic pressure generator in accordance with the result of a comparison between the actually generated hydraulic pressure of the automatic hydraulic pressure generator and the necessary hydraulic pressure for the motion control.

摘要： A vehicle driving condition detection device is adapted to detect a vehicle running along a banked or laterally sloping road, as well as a lateral acceleration, and sideslip angle with good accuracy. The sideslip angle is estimated at a vehicle-body sideslip angle estimating circuit based on a steering angle &dgr;f, a lateral acceleration ÿ, a yaw rate {dot over (&thgr;)}, and a vehicle speed V. In addition, using a differentiating device, the estimated sideslip angle is differentiated to calculate a slip angular velocity. A subtracting device is provided at which a deviation is calculated between the slip angular velocity and a slip angular velocity detected at a slip angular velocity calculating circuit. The deviation can detect a banked or laterally sloping road due to the fact that the detected slip angular velocity at the slip angular velocity calculating circuit includes the gravity acceleration component that depends on the slope or bank of the road. Upon detecting a banked or sloping road, a deviation &Dgr;ÿ (={dot over (&thgr;)}·V−ÿ) is outputted from a switching device, and at a subtracting device the detected lateral acceleration ÿ is corrected by being subtracted with the deviation &Dgr;ÿ. On the basis of the resultant or corrected lateral acceleration ÿ, the vehicle-body sideslip angle is estimated. Such an estimation is made irrespective of the slope or bank of the road.

摘要： The present invention is directed to a monitor system for use in an automotive vehicle which includes wheel brake cylinders operatively mounted on wheels, respectively, and which includes a hydraulic pressure control apparatus for generating a hydraulic braking pressure in response to depression of a brake pedal. A difference calculating unit calculates a difference between a wheel speed of a wheel to be determined and a wheel speed of at least one reference wheel which is compared with a predetermined value, when a braking operation detection unit detects a braking operation. Then, a determination unit compares the difference with a predetermined value, and determines that the pressure circuit provided for the wheel to be determined is normal, when the difference is lower than the predetermined value. An output unit may be provided to produce an output signal when a period of time during which the difference continues to be equal to or greater than the predetermined value, exceeds a predetermined time.
