Aimed at the problems that the calculation of the ReedsShepp path is influenced by the final attitude, and can not be used directly in the navigation scene without goal direction requirements， this paper proposes an optimal path navigation scheme of ReedsShepp and the generation rules of control schemes. Its optimal characteristics in various environmental conditions are verified by the simulation. This path can be utilized for designing the navigation scheme, can effectively reduce the driving time and operation cost of the automatic driving vehicle, in one word, can be widely used in the navigation system of automatic driving vehicles such as UGV, UAV, USV and so on, realizing the purpose of driving them along with the optimal path under control
