摘要： An actively controlled suspension system which successfully prevent a vehicular height from abruptly changing even when failure of a vertical acceleration sensor occurs. The actively controlled suspension system introduces a technology in performing suspension control, such as bouncing control, to shape a vehicular attitude indicative sensor signal, such as vertical acceleration indicative signal by slicing the sensor signal level at a predetermined slice level. In view of suppression of abrupt change of vehicular height at any vehicular driving condition, the slice level introduced in the present invention is variable depending upon a vehicle speed.
摘要翻译：即使发生垂直加速度传感器的故障，也能够成功地防止车辆高度突然变化的主动控制的悬架系统。主动控制的悬架系统引入了执行悬架控制（例如弹跳控制）的技术，以通过将传感器信号电平以预定的限幅电平进行切片来形成指示性传感器信号，例如垂直加速度指示信号。考虑到在任何车辆行驶状态下抑制车辆高度的突然变化，本发明中引入的切片水平根据车辆速度而变化。

摘要： An active suspension system derives a target pressure to adjust fluid pressure in a working chamber (24L) of an active cylinder (24), on the basis of a difference between an actual height level and a desired or target vehicular height level. Pressure supply for the working chamber (24L) is so controlled as to establish the target height. The system detects a vehicular parking state wherein the vehicle speed is zero and a road wheel (12) is locked to limit the variation range of the fluid pressure in the working chamber at the target pressure.

摘要： An active suspension system includes a pressure holding mechanism with a pressure holding valve means which is maintained in conductive state for a given period in which the fluid pressure in a working chamber is gradually adjusted toward a predetermined neutral pressure level after turning OFF of a power switch. The pressure holding valve is, on the other hand, maintained in non-conductive state for. a given period until the fluid pressure is adjusted to the neutral pressure after turning ON of the power switch. A control means is provided for performing suspension control operation in response to various suspension control parameters for adjusting fluid pressure in a working chamber of a cylinder for regulating vehicular height and vehicular attitude. The control means being responsive to switching of the pressure holding valve from non-conductive state to conductive state for permitting pressure supply therethrough for maintaining a suspension control command value at a predetermined value essentially corresponding to a neutral pressure for a predetermined transition period so as to assure moderate increase of the fluid pressure.
