The invention provides a suspension control system that executes control of
actuators that apply a vertical force to the vehicle wheels depending on
the travel state of the vehicle, and at the same time, carry out power
generation by using the energy of the vertical motion of the wheels and
use the obtained energy to drive the actuator motor. In the suspension
control apparatus in which the vehicle wheels can receive a force in the
vertical direction from a motor, power generation is carried out by the
motor depending on the vertical motion of the vehicle wheels, and a
storage cycle that stores energy in a storage apparatus and a discharge
cycle that drives the motor by the energy stored in the storage apparatus
are repeated.
