Abstract
An apparatus for testing a pressure change rate of a component in an electro-pneumatic braking system of a commercial vehicle includes a pressure change rate test bench, a pneumatic loop configured to implement on-off control of air and detection on a pressure change rate of a tested component in an electro-pneumatic braking system of a commercial vehicle, a signal processing unit configured to acquire a pressure signal and a differential pressure signal and perform analog-digital conversion on the signals to provide signals recognizable by an upper controller and a lower execution component, and a control unit configured to communicate with the pneumatic loop and drive the components in the pneumatic loop to act by setting a control parameter to obtain test data of the tested component in the electro-pneumatic braking system of the commercial vehicle in the pneumatic loop.
