STUDY ON THE DYNAMICS OF TURNING TRUCKS EQUIPPED WITH EMERGENCY BRAKE ASSIST AND BBRAKE FORCE DISTRIBUTION SYSTEMS

Abstract

In Vietnam, statistics indicate that many traffic accidents involving automobiles stem from poor braking performance, particularly when vehicles turn on low-traction road surfaces, such as wet or slippery roads. This underscores the necessity of enhancing braking efficiency and maintaining vehicle directional stability. To address this issue, modern braking systems with electronic controls, such as Electronic Brakeforce Distribution and Brake Assist, have been widely implemented. This study employs Matlab Simulink software to simulate and evaluate the effectiveness of EBD and BA systems on trucks during turning maneuvers. Results reveal that, under conditions of dry, flat asphalt roads with a friction coefficient of 0.8 and a rolling resistance coefficient of 0.015, trucks equipped with EBD and BA systems reduced braking time from 8 seconds to 6.2 seconds and braking distance from 45m to 32m, while significantly improving directional stability. The study highlights the crucial role of advanced braking systems in enhancing traffic safety and provides a scientific foundation for designing and developing modern braking systems in the future.
