1. ) A method of maintaining a dynamic stability of a material handling vehicle having a vertical lift, the method comprising:

  • a) continuously calculating dynamic center-of-gravity parameters for the vehicle over a time interval during which the vehicle is moving, wherein a vertical position of the dynamic center-of-gravity is dependent on a position of the vertical lift;

    b) continuously calculating wheel loads based on the calculated dynamic center-of-gravity parameters; and

    c) adjusting vehicle operating parameters based on the calculated wheel loads and center-of-gravity parameters to maintain vehicle dynamic stability.
