Abstract—This study presents an experimental investigation into the braking dynamics of automobiles operating under typical road conditions in the Mekong Delta region, using a Kistler dynamic testing device. The primary objective of the study is to evaluate braking efficiency and capture key dynamic parameters during braking maneuvers with high measurement accuracy. The Kistler dynamic testing system was selected due to its ability to provide reliable, high-resolution data, allowing a precise assessment of braking performance under controlled experimental conditions. Braking tests were conducted at a constant initial vehicle speed of 80 km/h on road surfaces with friction coefficients of 0.5, 0.7, and 0.8. During each braking event, critical dynamic variables were recorded, including wheel slip ratio, vehicle speed variation during braking, vertical reaction forces at both the front and rear wheels, longitudinal body pitch angle, and braking distance. These parameters provide comprehensive insight into the braking behavior and stability of the vehicle under different friction conditions. Based on the experimental results, key input parameters were identified for the development of a future theoretical and numerical simulation model of vehicle braking dynamics. The close agreement between measured data and expected physical behavior demonstrates the reliability of the experimental setup and confirms the effectiveness of the Kistler dynamic testing device in capturing braking performance characteristics. The findings establish a solid experimental foundation for subsequent modeling and simulation studies aimed at improving braking efficiency and safety of automobiles operating in the Mekong Delta.
