ABSTRACT:
An electric control apparatus for a shock absorber disposed between unsprung mass and sprung mass of a suspension mechanism in an automative vehicle and provided with an electrically operated control valve for changing damping characteristics of vertical displacement of the sprung mass relative to the unsprung mass, wherein absolute vertical displacement velocity of the sprung mass and relative vertical displacement velocity of the sprung mass to the unsprung mass are detected to determine a target opening degree of the control valve in accordance with the detected absolute vertical displacement velocity and relative vertical displacement velocity of the sprung mass, and where variation of the target opening degree is allowed in a large range only when the direction of the relative vertical displacement velocity has changed and is restricted in a predetermined small range under other conditions where the shock absorber acts to absorb vibration of the vehicle body.
