Most of modern vehicles have the trailer hitch for meeting various customer needs, and automotive OEMs should confirm trailer capacity to customers not only for truck but also for passenger cars. In order to confirm the trailer capacity, there are many trailering related requirements such as propulsion, powertrain cooling, handling stability, braking, and structure durability performance. Among those, trailer handling is one of the most important part for active vehicle safety since the lateral instability of towing-vehicle-trailer combinations could cause the serious accident by unexpected dynamic behavior during cornering, especially the vehicle with the trailer exceeding the capacity. Hence, automotive OEMs have been trying to predict the lateral stability for the trailer handling performance at each trailer weight condition for determining the trailer capacity. This paper deals with the lateral stability of passenger-car and trailer combinations. Firstly, we build up a high-fidelity towing-vehicle-trailer ADAMS model based on the verified base vehicle and the trailer related parameters correlated with actual tests, and secondly perform the trailer handling performance simulation according to the test event defined in ISO9815 and SAEJ2664. Based on the simulation results, we evaluate the lateral stability of passenger-car and trailer combinations by damping of articulation angle which is quantified value of relative yaw angle between towing vehicle and trailer through Logarithmic Decrement Method And we also perform design sensitivity study to get meaningful results for various parameters such as hitch damping (Roll, Pitch, and Yaw), friction, and hitch loading condition for robust MBD-based vehicle ad trailer models and reliable simulation results.
