Abstract
A test device for an automatic pressure regulating valve of an electronic braking system includes a test device composed of an air supply, a pneumatic circuit, a valve, a sensor, a signal processing unit, and a control unit. By subjecting an automatic pressure regulating valve to a bench test including a functional test, a static performance test, a dynamic performance test, an air tightness test, a leakage test, and a brake chamber braking force test, the present disclosure avoids the high risk of a field test, improves the test efficiency, and ensures the test consistency. An automatic pressure regulating valve is tested before being loaded on a vehicle, and parameters of the automatic pressure regulating valve are continuously modified through tests to improve the performance, such that the automatic pressure regulating valve can meet the real-time, fast, independent, and accurate regulation requirements of EBS of commercial vehicles.
