Method and system for controlling autonomous vehicle

The control system comprises an acquisition unit, an analysis unit and a control unit, the acquisition unit acquires the road surface friction coefficient in the driving process of the automatic driving vehicle and the braking pressure and the braking distance when braking is needed, and the analysis unit sends the braking danger signal to the control unit when meeting the braking danger signal. Firstly, parameters about tire aging are collected, whether the performance of the automatic driving vehicle is reduced due to tire aging or not is judged, and a signal is given to whether the tire is replaced or not; and if the control unit obtains the signal that the tires are not replaced, the control unit combines the environment of the area, obtains the information of the maintenance point, gives a driving route to the automatic driving vehicle, and controls the automatic driving vehicle to run according to the standard speed. And the braking fault is researched and judged, so that the automatic driving vehicle c
