Abstract: With the development of commercial vehicles, consumers are increasingly demanding vehicle safety. Braking response time is an important indicator for evaluating the performance of pneumatic braking systems, and it is of great significance to study solutions to shorten the braking response time. The test shows that by optimizing the selection and layout of the pneumatic braking system, the braking response time can be effectively improved, the braking distance can be shortened, and the safety of the entire vehicle can be improved. The article analyzes the pipeline layout and optimization of the pneumatic brake system, and combines the test data to demonstrate the factors that affect the braking response time, and solidify some optimization schemes.
