Abstract
A system and method that maintains the dynamic stability of a material handling vehicle having a vertical lift. The method allows static vehicle properties, such as vehicle weight, wheelbase length, and wheel configuration, and dynamic operating parameters, such as vehicle velocity, floor grade, lift position, and load weight, to be accounted for when maintaining the dynamic stability of a moving material handling vehicle. The method may include calculating and predicting center-of-gravity parameters, wheel loads, and projected force vectors multiple times a second and adjusting vehicle operating parameters in response thereto to maintain vehicle stability.
