Development of a test bench for integrative evaluation of the pneumatic ABS/TCS performance

A test bench for integrative evaluation of the pneumatic activated ABS/TCS performance of a vehicle has been developed. The test bench is built based on the platform of Matlab/xPC. It can be used to test the performance of ABS/TCS ECU and the characteristic of pneumatic solenoid valve. It can also be used in guiding the design of a ABS/TCS product for original equipment manufactures (OEMs), or find the most suitable product among various market available ABS/TCSs for specific vehicle application for a vehicle manufacturer. The scheme of hardware and software of the bench is described in detail. The tests of braking and starting performance of a vehicle with ABS/TCS driving on the road with low adhesive coefficient and the road which experiences sharp changes in adhesive coefficient and the operating characteristic of the solenoid valve are taken as major test contents. The test results show that the bench can completely emulate the real operating characteristic of a ABS/TCS system as its operating on real roads.
