Design and application of testing system for pneumatic ABS ECU

As the core control unit of ABS system, ECU plays an important role in evaluating the safety standards of the ABS system, it can be used to control the executive unit according to the state parameters of vehicle. Aimed at the high-cost, complex and long in the road test, an improved ABS ECU test system for the pneumatic ABS is proposed in this paper. Composed of finished ECU, data acquisition card, V/F convertor and PC, the system accomplishes the establishing of vehicle, brake and braking air pressure model for realistic simulation, and the dynamic loading method is used to load the different model on PC. Using the system, we can test and evaluate the signal processing ability, communication capacity and the effectiveness of the controlling algorithm of ECU. Finally, a type of ECU produced by one company is taken as an example to verify the feasibility of the testing system, and the results show that the system is available for practical application for its low-cost and short-cycle.
