Quadrature scheme is a scientific method of arranging multi-factors and multi-standards, because it can get enough experiment information with less experiment times, so it is suitable for multi-factor and multi-level experiments. In this paper, the orthogonal test method is adopted to design the test scheme to analyze the influence of vehicle quality and driving speed on vehicle handing stability. And the order and contribution rate of every experiment factor on target index is determined by
