摘要： A suspension pressure control system applies a pressure which is proportional to a current level supplied to a solenoid of a pressure control valve to a shock absorber associated with a suspension from the valve. When a pressure in a high pressure line which feeds a high pressure to the pressure control valve falls (rises), the pressure applied to the suspension is decreased (increased). Accordingly, the pressure in the high pressure line is detected by a sensor, and if it is low (high), the current level of the pressure control valve is corrected to a high value (low value). In order to prevent an abnormal pressure rise in the suspension which may be caused by an excessive pressure rise in the high pressure line during an idling operation of an engine, a correction which responds to the pressure of the high pressure line is chosen large when a vehicle speed is equal to zero or very low. In order to prevent an abnormality from occurring in the correction of the pressure which is attributable to an errorneous detected value during a failure of operation of sensor, such detected value is determined to be faulty, and in the event a fault occurred, the correction is modified to a given volume (0) which is allocated to a standard pressure in the high pressure line.

摘要： In a hydraulic suspension system, a plurality of actuators having working fluid chambers are provided. Each actuator is adapted to increase and decrease vehicle height as the results of the supply and the discharge of working fluid to and from its working fluid chamber, respectively. Working fluid supply passages supply working fluid at supply pressure to the working fluid chambers and working fluid discharge passages discharge working fluid from the working fluid chambers. Cut-off valves and pressure control devices are provided in the supply passages and the discharge passages. Each cut-off valve is adapted to remain in its closed position whenever the supply pressure is not more than a predetermined value. Each pressure control device is adapted to control the supply of the working fluid to and the discharge from the associated working fluid chamber to adjust the pressure within the chamber. The system further comprises devices for detecting the pressures within the working fluid chambers and a device for determining the supply pressure. The pressure control devices are controlled so that their controlling pressures may substantially be equal to the pressures within the associated working fluid chambers determined by the pressure determining devices at least until the cut-off valves are opened.

摘要： In a hydraulic active suspension system, a plurality of actuators having working fluid chambers are provided corresponding to vehicle wheels. Each actuator is adapted to increase and decrease vehicle height as the results of the supply and the discharge of working fluid to and from its working fluid chamber, respectively. Supplying and discharging devices supply working fluid to and discharge from the working fluid chamber. Vehicle height sensors detect the vehicle heights at the locations corresponding to the vehicle wheels. A control device is further provided. The control device controls the supplying and discharging devices so that the pressure within the working fluid chamber in each actuator may be a value corresponding to the sum of a basic pressure determined according to the running conditions of the vehicle and a compensating pressure determined based upon the integral value of the difference between a standard vehicle height and an actual vehicle height. When the integral value of the difference is larger in magnitude than a predeterminate value, it is reduced in magnitude by the control device so as to prevent the control with the compensating pressure from overriding the control with the basic pressure.

摘要： In a hydraulic active suspension system, a plurality of actuators having working fluid chambers are provided corresponding to the vehicle wheels. Each actuator is adapted to increase and decrease vehicle height in response to the pressure within its working chamber, which is controlled by a pressure control device. Vehicle speed and vehicle heights at the locations corresponding to the vehicle wheels are detected by corresponding sensors. A control device is further provided for controlling the pressure control device so that the pressures within the working fluid chambers are driven to substantially the desired pressures, the desired pressures determined by, at least, the sum of the first control parameters corresponding to the differences between the actual vehicle heights detected and the associated desired vehicle heights and the second control parameters corresponding to the changing amounts of the vehicle height differences. The second control parameters are so set that the higher the vehicle speed is, the higher the second quantities are in magnitude, enhancing the controllability and stability of the vehicle under higher vehicle speed conditions and ensuring a greater comfortability level of the vehicle under lower vehicle speed conditions.

摘要： In a hydraulic active suspension system, a plurality of actuators having working fluid chambers are provided corresponding to vehicle wheels. Each actuator is adapted to increase and decrease vehicle height in response to the pressure within its working chamber, which is controlled by a pressure control device. Vehicle speed and lateral acceleration are detected by corresponding sensors. A control device is further provided for controlling the pressure control device by compensating values determined base upon the lateral acceleration detected. The control device is adapted to reduce the compensating values in magnitude when the vehicle speed is lower than a predetermined value under which the lateral acceleration sensor sometimes detects a false lateral acceleration, thereby reducing the possibility that the vehicle body may generate an unpleasant roll due to the erroneous control on the pressures within the working fluid chambers based upon a false lateral acceleration.

摘要： An object of the invention is to increase driving force of driving wheels at starting a vehicle, when the vehicle runs on a μ-sprit road. At first, a road surface for a driving wheel is detected, which has a higher coefficient of friction than that of a road surface for the other driving wheel. An operation for controlling grounded load of the driving wheels is carried out during a period, in which differential rotations of the driving wheels are limited. The grounded load of the driving wheel which is traveling on a high-μ road is increased, whereas the grounded load of the other driving wheel which is traveling on a low-μ road is decreased.

摘要： A vehicle brake control device includes a brake member, a wheel brake cylinder mounted on a wheel, and a master cylinder. The master cylinder generates a master cylinder hydraulic pressure in response to an operating force applied to the brake member. The brake control device also includes an automatic pressure increasing control device, a braking force control device, a coefficient of friction detecting device that detects a coefficient of friction of the road, and an automatic pressure increasing restraining device. The automatic pressure increasing control device controls automatic pressure increasing operation of the master cylinder based on the operating force applied to the brake member. The braking force control device controls the increased master cylinder hydraulic pressure supplied to the wheel brake cylinder. The automatic pressure increasing restraining device restrains automatic pressure increasing operation of the master cylinder when anti-skid control is being performed with a low coefficient of friction.
