Hardware part of the test bench includes air brake system, dSPACE real-time simulation system, sensor and driving simulation platform. Software part of the test bench includes vehicle dynamics model, real-time software of RTI and test software ControlDesk, as well as control algorithm for the controller. On the basis of the hardware-in-the-loop test bench, real-time communication with the vehicle model under various braking conditions, as well as acquisition of feedback information during vehicle braking control can be implemented. The bench can be adopted for verifying the control strategy of ABS controller quickly. The application results have shown that test results got from the proposed hardware-in-the-loop test bench for pneumatic ABS controller prototype are accurate and correct, and it can shorten the development cycle and save development costs significantly.
