摘要： A suspension apparatus has suspension units which have individual fluid spring chambers and are arranged on the wheels. When a detected negative acceleration (deceleration) exceeds a reference negative deceleration, front wheel fluid supply valves are opened for a control time T to supply a predetermined amount of fluid to the front wheel spring chambers and rear wheel fluid extent valves are opened for the control time T to exhaust a predetermined amount of fluid from the rear wheel fluid spring chambers, thereby decreasing nose dive at the time of deceleration.

摘要： The characteristic of the suspension is held to be a soft one when the vehicle is running along a flat surface, while it is automatically switched by the switch unit to a hard one when the cycle period T of vertical vibration of the vehicle height becomes near the cycle of the natural vibration of sprung mass of the suspension at the time of running along a road having an irregular surface or jumping a projection, thereby suppressing the resonance of the vehicle body due to external force applied from the road to improve the comfortability.

摘要： A vehicle suspension apparatus including suspension units each provided for each wheel and having an air spring chamber is disclosed. When steering wheel is quickly returned toward the center position at the time of a slalom running, it is detected from the steering angular velocity and vehicle velocity that the vehicle body has begun to be returned to a neutral state, and communication control valves are opened before the reaching of the center position, i.e., before the steering angle reaches an insensitive range. Rolling control thus can be improved without delay in the restoration of the position of the vehicle body even at the time of a high speed slalom running, at which time the steering wheel is repeatedly operated quickly.

摘要： A vehicle suspension apparatus including suspension units each provided for each wheel and having an air spring chamber is disclosed, in which rolling control and vehicle height control are done through control of air to and from the air spring chambers. The driving of a reservoir tank for storing compressed air to be supplied to the air spring chambers, is inhibited until the engine operation has been stabilized after the start of the engine preset level. In this way, the problems in the engine lubrication and idling are solved, and the defficiencies of the starting property of the engine are overcome.

摘要： The front wheel exhaust valves and the rear wheel supply valves are opened for a predetermined period of time when rapid acceleration of the vehicle is detected by the accelerator pedal sensor and the gear position sensor, the absolute value of change in vehicle position and its velocity can be properly controlled. Therefore, comfort and steering stability can be improved as compared with vehicles mounting of the conventional apparatus. In addition, since an acceleration state is detected by the gear position sensor as well as the accelerator pedal sensor, rapid acceleration of the vehicle can be accurately detected, thereby preventing unnecessary position control.

摘要： A suspension apparatus has suspension units mounted on wheels and each unit has a fluid spring chamber. Fluid is supplied to contracted fluid spring chambers and is exhausted from elongated fluid spring chambers to control the change in position of the vehicle. In the position control mode, a large-diameter path is selected to supply or exhaust a large amount of compressed fluid. In the height control mode, a small-diameter path is selected to supply or exhaust a small amount of compressed fluid. The required amounts of compressed fluid can be supplied to the fluid spring chambers in both the position and height control modes.
