  • judging that the vehicle is either moving straight forward or is stationary;

    calculating an imbalance amount representing the degree of imbalance among actual contact loads of all the wheels on a ground surface when the vehicle is stationary or is moving straight;

    determining whether said imbalance amount exceeds a predetermined value; and

    changing said reference vehicle heights for at least two of said suspension units when said imbalance amount exceeds said predetermined value, the vehicle height adjusting means independently controls each of said suspension units based on the changed reference vehicle heigth.
