摘要： According to the present invention, as soon as the sporadic protrusion or sinking of a road surface is detected at the front wheel of the vehicle during its running on the road surface, the air chambers of the air suspensions for the right and the left rear wheels of the vehicle are connected to each other to alter the spring constant of the rear suspensions to `soft` when the rear wheel passes over the sporadic protrusion or sinking of the road surface, so that the feel of ride of the vehicle and the controllability and stability thereof are kept good. After the rear wheel moves over the sporadic protrusion or sinking, the characteristic of the rear suspensions is returned to the original state appropriate to the normal running state of the vehicle. Detectors for the sporadic protrusion or sinking of the road surface may be provided for the right and the left front wheels of the vehicle, respectively. The rear suspensions of the vehicle can be more appropriately controlled by that.

摘要： A suspension controller for controlling the suspension characteristic of a vehicle having a suspension which supports a vehicle body on plural wheels, wherein the distance between the vehicle body and at least one of the wheels is measured and a corresponding signal indicating the height of the vehicle is produced. This height signal is compared against preset reference signals and the characteristic of the suspension is altered, e.g., the suspension is made harder or softer, in dependance on the comparison. Additionally, the preset reference signals themselves are changed depending upon the alteration in the characteristic of the suspension. Changing the reference signals eliminates influence of the change in the amplitude of vibration of the height of the vehicle as a result of altering of the suspension characterisitc, whereby exact detection of a change in the amplitude of the vibration due to irregularities of the road surface is enabled to prevent overcontrol and hunting.
摘要翻译：一种悬架控制器，用于控制具有支撑多个车轮上的车身的悬架的车辆的悬架特性，其中测量车体与至少一个车轮之间的距离，并且指示车辆高度的相应信号是生产。将该高度信号与预设的参考信号进行比较，并且根据比较改变悬架的特性，例如，使悬架变得更硬或更软。此外，预设参考信号本身根据悬架的特性的变化而改变。改变参考信号消除了由于悬架特性的变化而导致的车辆高度的振动振幅的变化的影响，由此精确地检测由于路面的不规则性引起的振动振幅的变化是能够防止过度控制和狩猎。

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.
