The long body, high hazard factor and complex braking system of tractor semi-trailer make it difficult to conduct real-world tests in the development of the ECPBS (Electronically Controlled Pneumatic Brake System) controller. In order to reduce the number of real-world tests, accelerate the development of the controller and achieve rapid verification of the control strategy, this paper proposed a test system scheme integrating model-in-the-loop and hardware-in-the-loop test methods. Based on the circuit structure of the ECPBS of tractor semi-trailer, a model of the braking system was established using AMESim and embedded in the IPG simulation platform to realize the model-in-the-loop test function. An ECPBS controller was built based on the dSPACE real-time system and interconnected with a bench simulating the braking system of a real vehicle to realize the hardware-in-the-loop test function. A generic ECPBS control strategy was developed and tested on this test system. The results showed that the accuracy and reproducibility of the test system are well performed and can provide a reliable platform for the development of ECPBS controllers for tractor semi-trailer.
