Abstract: The general scheme of the automatic steering car with potential energy is determined. Based on the requirements of the self-steering vehicle, a creative design and analysis of vehicle is presented with a view to striving for a simple structure with function decomposition, and in which kinematics and dynamics were utilized. How to raise the running accuracy of the vehicle was discussed. Finally, the design case of the car is given, which can meet the requirements of the expected motion precision.

Key words: self-steering vehicle, structural design, mechanism design
