    摘要： A microcomputer performs roll control and communication control. In roll control, when the steering state detecting means and vehicle velocity detecting means detect a factor which causes a roll state of the vehicle body, a second control signal is produced to open desired supply and exhaust control valve so as to supply a preset amount of fluid to the fluid spring chambers of contracted suspension units and to exhaust a preset amount of fluid from the fluid spring chambers of stretched suspension units. In communication control, a first control signal is supplied to the communicating means to open the communication control valve when the steering state sensor detects that the steering angle falls within a preset steering angle and to close the communication control valve otherwise. After generation of the first control signal, when the steering state sensor detects that the steering direction of the steering wheel is in a return direction toward the neutral position and the steering angular velocity is lower than a preset steering angular velocity, a third control signal is supplied to the communicating means so as to open the communication control valve. When the steering state sensor detects, a third preset time after a second preset time from the generation of the third control signal, that the steering angle has reached the preset neutral range, a fourth control signal is produced to close the communication control valve for a fourth preset time.

    摘要： In a vehicle suspension apparatus having air spring chambers between the vehicle body and the respective wheels to perform height and position control modes by controlling supply control valve means for supplying air to the air spring chambers and exhaust control valve means for exhausting air from the air spring chambers, the vehicle suspension apparatus has a high-pressure reserve tank connected to the respective chambers through the supply control valves, a first compressor for supplying compressed air to the high-pressure reserve tank, a low-pressure reserve tank connected to the respective chambers through the corresponding exhaust control valves and the suction port of the first compressor, and a second compressor for supplying atmospheric air to the high-pressure reserve tank through a check valve and a drier arranged between the check valve and the second compressor. In the position control mode, the compressed air is exhausted from the chambers to the low-pressure reserve tank through the exhaust control valves. In the height control mode, the compressed air is slowly exhausted from the corresponding chambers through the exhaust control valve means via the drier, thereby regenerating the drier during height down control.

    摘要： In a vehicle suspension apparatus, front and rear wheel suspension units respectively have air spring chambers. Air is supplied to predetermined air spring chambers from an air source through a supply control valve, and at the same time air is exhausted from remaining air spring chambers through an exhaust control valve. Three-directional valves are inserted between the respective air spring chambers and the exhaust control valve. One end of a front wheel communication path is connected to the front left wheel three-directional valve and the other end of the path is connected to the front right wheel three-directional valve. Similarly, one end of a rear wheel communication path is connected to the rear left wheel three-directional valve and the other end of the path is connected to the rear right wheel three-directional valve. The air passing through the supply control valve is supplied to the front wheel air spring chambers through the front wheel communication path or to the rear wheel air spring chambers through the rear wheel communication path. Each of the three-directional valves can take the first position where the air spring chambers communicate with the supply control valve or the second position where the air spring chambers communicate with the exhaust control valve, thereby decreasing the numbers of valves and paths so as to perform position control.

    摘要： In a vehicle suspension apparatus comprising communication control means for producing a disabling control signal for disabling the communicating solenoid valves when conditions are satisfied that the velocity detected by the velocity sensor exceeds a preset velocity and the steering angle detected by the steering sensor exceeds a preset steering angle and for producing an enabling control signal when the conditions are not satisfied, and roll control means for producing a control command signal for opening desired ones of the supply and exhaust control valves for a preset control time in order to supply a preset amount of fluid to contracted fluid spring chambers along a roll direction and for exhausting a preset amount of fluid from stretched fluid spring chambers when the conditions are satisfied, the preset velocity as one of the conditions determined by the communication control means is set to have a first value when the communicating solenoid valves are enabled and to have a second value larger than the first value when the communicating solenoid valves are disabled. With this apparatus, passengers experience uniform centrifugal force sensations when roll control is started and cancelled. Discomfort experienced by passengers during and after roll control is reduced to a minimum.
