Abstract
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.
