摘要:
A suspension control system for an automotive vehicle is provided in which a movement of a sprung mass velocity is monitored, when the magnitude of the sprung mass velocity is below a predetermined threshold value, a control unit outputs a control signal to a pulse motor to vary the position of an adjuster so that one of extension and compression stroke sides of a position member of a shock absorber, whose direction is the same as that of the sprung mass velocity provides a high damping coefficient, and when the magnitude of the sprung mass velocity is above the predetermined threshold value, a control constant for the damping coefficient is changed toward a high damping sensitivity range until the sprung mass velocity exceeding the predetermined threshold value is reduced below another predetermined threshold value, a magnitude of the other predetermined threshold value being lower than that of the predetermined threshold value.
