ABSTRACT:
A suspension control apparatus comprises a sprung velocity measuring device for measuring a sprung velocity, a relative velocity measuring device for measuring a relative velocity between the sprung and unsprung velocities, a controller for mode-converting, weighting and inversely mode-converting the sprung velocity and relative velocity, and having a dead zone setting circuit for changing over a control value when the polarity of the velocity difference is inverted at a first time, in order to calculate a velocity ratio and determine a target damping force, and an actuator for controlling the opening area in the variable throttle mechanism communicating with the cylinder piston apparatus of absorber was disclosed. The suspension control apparatus has the effect that there is no delay in controlling and any shock and the generation of hunting is prevented.
