“…The main factors affecting braking performance are vehicle weight, the structure of the braking system, braking effectiveness of the front-rear wheels, the design of the braking system, the condition of the brake hydraulic and mechanical parts, the environmental conditions that may affect the braking system, the condition of the tires, the load on the vehicle, road conditions, braking settings, the wheel -is the coefficient of friction and adhesion between the road [3]. However, there are still many problems in the vehicle stability and the braking performance [4]. Load sensing brake proportioning is a means of optimizing the ratio of front-to-rear wheel retarding forces for the full range of vehicle loadings and decelerations [5].…”

The brake system is used to keep the speed of the moving vehicle con-stant, slow down, stop it and fix it while parked. Heavy vehicles have an air braking system. (71/320/AT) It should be produced in accordance with the regulations of motor vehicle classes and brake systems. Periodic tests should be carried out in authorized institutions. In the brake systems of vehicles in Trucks, Trailers, Trailers, Semi Trailers, Buses, load adjusting valves called ALB are used, which increase or decrease the rear brake forces of the vehicle according to the load of the vehicle. ALB can be used mechanically or pneumatically in heavy vehicles. In this study, a test device was designed us-ing the microcontroller card, pressure sensor and LCD screen in order to ena-ble the operator, who performed the pneumatic ALB test, to perform the test alone without help and to increase the reliability of the test. As a result of the study, the operator was able to perform the Pneumatic ALB test alone, in-crease the reliability, and save time and labor.

Heavy commercial road vehicles have a longer stopping distance, owing to the inherent time lag associated with the conventional air brake system used in them. In general, electropneumatic brake systems would respond more quickly, resulting in a shorter stopping distance; these are the focus of this study. In an earlier work, the best configuration of the electropneumatic brake system was determined, considering both response and cost perspectives. This study focuses on the development of an experimentally corroborated mathematical model for this brake system. Non-linear model-based deceleration and brake chamber pressure control schemes were subsequently developed and their performance evaluated using a hardware-in-loop system. The model-based analysis and the control schemes presented in this article will assist in the development of advanced and cost-efficient active safety systems for heavy commercial road vehicles.

Abstract. The performance of the braking system has an important influence on the safe operation of the train. In this paper, the AMESim simulation software is used to simulate the pneumatic valve unit (PVU) for the direct electro-pneumatic braking system controlled by the microcomputer. And the correctness of the model is verified by the simulation of the service braking and the emergency braking. At the same time, the vehicle dynamics model is built in the MATLAB/Simulink environment, and the AMESim pneumatic valve model is combined with the simulation to verify the effectiveness of the anti-skid logic. The simulation results from the service braking and emergency braking can be drawn that the PVU for the direct electro-pneumatic braking system controlled by the microcomputer is consistent with the response of the real system, which verifies the correctness of the PVU model. It can be seen from the simulation results that the anti-skid control logic can achieve the control requirements, and can achieve the stability of the anti-skid effect in the event of a continuous sliding. The results of this study provide an effective model base for the design of the actual vehicle braking system and solutions to the fault.
