A new test method esp / abs accumulator test device

The present invention relates to the field of automotive test apparatus designed to provide a new ESP / ABS Test Method for testing the accumulator means, comprising a test circuit in the ESP / ABS pieces to be tested, the test circuit and connected to the reciprocating means a hydraulic cylinder, proportional valve, a pressure sensor, a displacement sensor, and IPC. The present invention does not need to do a test piece assembly, controlled by a liquid gas simplifying / saving the required test equipment, the circuit can be simulated vehicle brake hydraulic pressure boost / pressure, so that ESP / ABS environmental test piece to be tested and closer to the actual use conditions; the present invention accumulator PV performance curves and durability test, can be of ESP / ABS accumulator performance direct, accurate, rapid test, to predict in advance, reducing the risk of failure.
