Abstract
Judgement of a rough road is made when detecting the number of upward and downward movements exceeding the set range of the vehicle height within a predetermined period of time by the vehicle height sensors or when detecting the upward and downward acceleration exceeding the set value within a predetermined period of time by an acceleration sensor. Since a high vehicle height is automatically set as a target vehicle height to control the vehicle height toward the same high vehicle height by the control unit, the minimum ground height of the body is raised to reduce a contact of the body with the surface of the road, thereby improving drivability of a vehicle on a rough road and decreasing damage of the body. Therefore, even if the first condition is not satisfied by the vehicle height sensor after the vehicle height is controlled to the high vehicle height, the second condition is satisfied by the acceleration sensor to reliably judge the rough road, thereby eliminating a hunting of controlling the vehicle height when traveling on a rough road as in the conventional apparatus.
