Abstract
10.7467/KSAE.2023.31.11.919
Heavy-duty vehicles have a large mass and a large payload, and high braking power is generated when using only mechanical brakes. As a result, phenomena such as fade and vapor lock occur, leading to the risk of loss of braking power. Therefore, an auxiliary brake system is installed in addition to the main brake. In this study, a mathematical performance model and a braking control logic for a hydraulic retarder, which is an auxiliary braking device mounted on the transmission output shaft, were developed. Moreover, a simulator for the vehicle braking system was developed to analyze braking control performance on actual roads, while the reliability of the control logic was verified through a comparative analysis of the test data.
