【Abstract】Signal processng and modeling of automotive electronic control systems directly affectvehicle performance andfunctional safety.Thearticle mainlystudies technologies suchas noisereductionof sensor signalsandoptimizationof instruction transmision，andconstructs thedual time scalemodelof powertrain，the parameterization methodof vehicle dynamicsand thehybridlogicmodelof intellgentdriving.Through theintegrationverificationof hardware-in-loop（HIL） and digital twin technology，it was found that the hybrid H2/H∞ control can improve the closed-loop accuracy，and the time-domaindecouplingcan handletherigidityproblemof themodel.Theresearchprovides theoriesandverification methods for the optimization of system architecture.
