For acceleration slip regulation system(ASR), the traditional method develops the control algorithm through vehicle road experiments, which needs a long period and a high cost. The experiments are only carried on after the development of ECU hardware, which can’t meet the requirement of parallel engineering of software and hardware. The ASR controller was developed based on the V-flow method. Then the development of ECU was accomplished, by the modeling and simulation of ASR system, implementation of rapid control prototype(RCP), hardware-in-the-loop simulation(HILS), and the vehicle road tests. The research results indicate that the developed ECU can realize the ASR function preferably, and the V-flow developing method is ascendant to develop of the vehicle electronic control systems.
