Our Daily Driving condition can be divided two conditions one is steady state and the other is transient. Look at our real life driving. How many steady state driving conditions occur? There is no one can answer definitely. Most our driving conditions are transient driving in point of view by change of accelerations. But up to now vehicle dynamics simulation and test were tend to focus on steady state handling performance, So we often met difficulties in correlation steady state handling performance prediction vs. subjective driving evaluation result. To reduce this gap, we focused on transient handling Simulation and Vehicle evaluation. Hence we wrote this paper. Transients are influenced by many suspension parameters. In this paper, we select one parameter only ? Jounce bumper and we are going to discuss this part only. This paper was summarized transient handling improvement history by tuning jounce bumper stiffness and length. First all we establish evaluation guide line for what, How evaluate on transient handling conditions. And Through benchmarking test, we compared suspension performance of recent vehicles. Especially we focus on jounce bumper and we selected best in segment vehicle and we targeted that vehicle for new development vehicle. Jounce bumper tuning sample were used improve transient handling by subjective and objective test, Evaluation. So we can see potential of transient handling improvement by jounce bumper which use prevent impact force of suspension.
