Abstract：

The　vehicle　dynamics　models　which　have　integrated　electric　power　steering　(EPS)　and　active　suspension　system　(ASS)　were　built,　the　integrated　LQG　(Linear-Quadratic　Gaussian)　controller　which　adopts　centralized　structure　was　designed,　computer　simulations　were　carried　out　with　the　MATLAB/Simulink　software.　The　simulation　results　showed　that　the　LQG　controller　could　not　only　apparently　filter　sensor　measurement　noise　influencing　the　integrated　systems,　but　also　effectively　improve　vehicle　handing　stability　and　steering　portability.　©　the　authors.
