developments in electronics, and DrivebyWire is one of the most important technologies. ETCS (electronic throttle control system) is one part of the powertrain control system, it plays a very importantrole in powertxain control. This thesis firstly introduced the ETCS, then modeled and simulated its dynamics and electrics characters in Matlab/simulink/stateflow, and the model based embedded software code isgenerated, then test is curried out in the realtime workshop.The whole thesis consists of six sections.Riefly states the ETC technique developinghistory, features, the current application situation and products, and then points out the significance of the thesis and the main content of the research work.Analyzes the dynamics of each part of the throttle body, including pneumatics, spring torque, friction etc, and then deduces mathematical model of ETCS. And system identification is also done using the toolbox of Matlab.In the mechanical and electrical control s
