Automobile robust stability quantitative evaluation method and evaluation system based on H-infinity norm

The invention particularly relates to an automobile robust stability objective quantitative evaluation method and evaluation system based on an H-infinity norm, and the method comprises the steps: solving a stable balance point of a high-degree-of-freedom nonlinear vehicle model through a homotopy method, and constructing an interference scene for the vehicle model; a high-degree-of-freedom linear vehicle interference model at a stable equilibrium point is obtained by using a Jacobian linearization method, and the high-degree-of-freedom linear vehicle interference model at the stable equilibrium point is obtained by using the concept of an H-infinity norm in an H-infinity robust control theory, taking the high-degree-of-freedom linear vehicle model as a research object and taking a specific interference environment as a research scene. And a vehicle robust stability quantitative evaluation index based on an H-infinity norm is established, so that the problem of lack of robust stability objective quantitative
