    摘要： An electronic fluid suspension system having longitudinal acceleration sensor, acceleration difference calculation means and vehicle attitude control means in addition to other fluid flow control components known in the conventional suspension system. In this system, the vehicle attitude is controlled responsive to the difference between a maximum acceleration and a minimum acceleration detected within a predetermined time interval. When dive or squat of the vehicle body is anticipated by the difference, vehicle attitude control is performed, without inappropriately responding to a momentary change in the acceleration. After the vehicle attitude control, a return control is performed to restore the original attitude and, further, a vehicle attitude correction control is performed responsive to a difference in actual front/rear heights and corresponding original heights.

    摘要： Provided is an electronic controlled air suspension system consuming less energy in preparing air in the high pressure reserve tank and low pressure reserve tank. Until the total sum of pressures of high pressure reserve tank and low pressure reserve tank reaches a predetermined first value, the pressure in the low pressure reserve tank is preferably controlled. After that, air in the low pressure reserve tank is supplied to the high pressure reserve tank until the pressure in the high pressure reserve tank reaches a desired value. In another feature of the invention, air is rapidly charged to the high pressure reserve tank regardless of the above procedure when a rapid charging to the reserve tanks are needed. This ensures continuous operations of rapid vehicle attitude control.

    摘要： An electronically controlled fluid suspension system detects an average longitudinal or lateral acceleration within a predetermined period, computes an acceleration difference between a maximum average acceleration and a minimum average acceleration. Based on the acceleration difference, an estimated longitudinal or lateral acceleration is computed. In response to the estimated longitudinal or lateral acceleration, computed are a height-raising quantity of a lowered portion of a vehicle and a height-lowering quantity of a raised portion thereof. The supply and release of a fluid to and from fluid springs is rapidly controlled so that the height-raising quantity of the lowered portion of the vehicle is less than the height-lowering quantity of the raised portion thereof. The electronically controlled fluid suspension system, thus, prevents the vehicle from inclining due to changes in driving status, and enhances a road-adherence ability on an uneven road as well as a steering stability.

    摘要： An electronically controlled fluid suspension system for preventing the lateral roll of a vehicle computes a predetermined estimated lateral acceleration based on the running speed and the difference between the maximum steering angle and the minimum steering angle within a predetermined period. The supply and discharge of the air to and from the air springs is rapidly controlled corresponding to the estimated lateral acceleration so as to prevent the vehicle from rolling due to the steering operation. Moreover, the electronically controlled fluid suspension system computes a predetermined target vehicle height based on the lateral acceleration. After the air is supplied and discharged to and from the air springs and the increase of the lateral acceleration is stopped, the vehicle height is restored regardless of the external disturbance, by controlling the supply and discharge of the air corresponding to the vehicle height difference between the target vehicle height and the actual vehicle height.
