Abstract: In the suspension control apparatus of the present invention, a CPU determines a desired damping force, based on an acceleration of a car body in a vertical direction, which is detected by an acceleration sensor, and also determines a PWM duty ratio corresponding to an intensity of a target current (an average intensity of the applied current) required for generating the desired damping force. Further, the CPU detects a voltage provided by a battery and adjusts the PWM duty ratio, based on the detected voltage value, so as to maintain a dither amplitude at a predetermined level. A PWM signal having the adjusted duty ratio is outputted to a transistor, to thereby apply a current which is obtained by superimposing a dither on the target current.
