| Anti-lock Braking System(ABS)is a kind of machtronics equipment, which is based on traditional braking system, using electronic control technique to realize auto-adjusting of braking pressure. It keeps the wheel from lock when braking, which can get the highest braking efficiency and enhance the safety of vehicle.Generally speaking, hydraulic Anti-lock Braking System has three important components: Speed Sensor,Electronic Control Unit and Hydraulic Control Unit. Hydraulic Control Unit is the implement outfit of ABS. The dynamic respond characteristic of it plays an important role to ABS. It is the main fact that can influence the performance of ABS. In this paper, through founding a testing system which could meet the need of testing ABS Hydraulic Control Unit Solenoid valve capability and ABS Hydraulic Control Unit capability, we do a great deal of testing of ABS Hydraulic Control Unit Solenoid valve and the ABS Hydraulic Control.The paper is to investigate and design the whole testing scheme, according to the capabilities testing content of ABS Hydraulic Control Unit. The analysis and research is in the aspect of hardware designing and software designing. The design of test-bed behaves collocate of machinery- electricity- hydraulic integrative equipment, which makes the system perform the test commendably and has high degree of automatization.Through ABS Hydraulic Control Unit capacity testing, it indicates that, the test-bed could perform the solenoid valve test and the whole test of ABS Hydraulic Control Unit. It has great actual engineering value to enhance the veracity and work efficiency of ABS Hydraulic Control Unit capacity testing. |
