摘要： When a car is stationary, the driver may test the attitude control of a suspension pressure control system by ordering with specific switches a rolling test or a pitching test. Assuming he chooses a rolling test and rotates a steering wheel towards the right, the vehicle inclines laterally such that a height of the left side of the vehicle rises up and the height of the right side falls down by an amplitude responding to the rotation angle of the steering wheel. Whenever a longitudinal inclination is superimposed to the rolling, the driver is able to detect a failure of the control system and to pinpoint the faulty suspension.

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 value (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： An electronic controlled suspension system detects a load on the fluid actuators and calculates a torsional load on the vehicle. Responsive to the calculated torsional load, corrective control is executed on the fluid flow to and from the fluid actuators, eliminating torsional load on the vehicle. Therefore, the driving characteristic is prevented from changing due to an unbalanced load on the vehicle. On the other hand, the electronic controlled suspension system detects a vehicle's cornering state. Responsive to the cornering state detected, control signals are output to increase the roll stiffness distribution to the front wheels. As a result, the roll stiffness distribution to the front wheels while the vehicle is about to corner becomes larger than that while the vehicle is steadily cornering. Responsive to the control signals, the vehicle attitude is controlled by supplying and discharging fluid to and from fluid actuators. Consequently, when the vehicle is just starting to corner, laterally moving load is controlled, and quick-responsive steering is realized.
