The automotive electronic control system′s semi-physical simulation solution based on the Jetta 1.6AT car is proposed,and its semi-physical simulation platform is designed and developed combining the actual automotive with the model environment organically using hardware interface circuit by means of the semi-physical simulation.The platform designed can realize real-time data exchange between vehicles and hardware-in-the-loop simulation model as well as accurately capture vehicle sensor signals.The vehicle electronic control system′s work process and control principle can be observed visually through the platform display system.And according to the requirements,different models and different operating conditions are simulated by reasonably changing the parameters of simulation model.This platform not only solves the problem of real conditions simplification and modeling difficulty of mathematical simulation,but also overcomes high cost and long cycle of the physical test,and can be applied to the development,debugging,testing and teaching experiments of automotive electronic control systems.
