Typically for the design of vehicle control systems and the test of electronic control units, using Hardwarein-the-Loop （HiL） simulation, HIL integrated the multibody system （MBS） analysis was studied. The Vehicle Electronic Embedded hardware in loop simulation platform owning intellectual copyright was embedded vehicle model based on vehicle real-time multibody dynamics subsystem synthesis method The dynamic model of the mobile, the characteristic model of electromagnetic valve, the model of braking system and the model of tire were analyzed, for use in HiL-simulators the equations of motion with open interfaces of the applied forces and torques were provided to be integrated in a modular dynamic ride model ECU hardware in loop simulation on vehicle security ESP （ABS） system was researched The experimental results show hardware in loop simulation platform based on real-time multibody dynamics model can quicken the development process of ESP vehicle security system, and improve control performance.
