ABSTRACT:
When vibrations having a period at which pitching tends to occur in a vehicle body is detected, if its amplitude falls out of the range between "H" and "L", a control unit increases the damping force of each suspension unit by using an actuator. In addition, if the amplitude falls out of the range between "HH" and "LL", the control unit supplies a predetermined amount of air to each air spring chamber in response to an upward displacement of vehicle height, and exhausts a predetermined amount of air from each air spring chamber in response to a downward displacement of vehicle height.
