Abstract: In order to revise the national standard GB/T 31970—2015, firstly, the importance of air disc brake (ADB) caliper in the air brake system of commercial vehicles is clarified by analyzing the technology and development trend of electronic parking brake (EPB) of commercial vehicles. Secondly, a test method of static characteristics of air disc brake caliper in parking is proposed, and the compilation principle, definition of relevant terms and specific test steps of this method are introduced in detail. Finally, a test bench of parking static characteristics is designed and developed, and the hardware selection and software implementation method of the test bench are described in detail. Through test verification, the test method of the proposed parking static characteristics is reasonable. The test bench data are accurate and consistent, and the relevant feature points have a strong guiding significance for the vehicle design and brake product design, which can be an important supplement to GB/T 31970—2015.
