 Abstract
 With the rapid development of computer technology and artificial intelligence, the smart car has been greatly improved in the functional and technical level. Without human management, it can operate automatically under the pre-determined model. As a result, the smart car can be used in scientific prospecting and industrial production for transporting, loading and blanking. Furth -ermore, it can also be widely used in tourism, medical care, and other industries.
 The technology of smart car is a research hotspot in recent years and self-driving is its most basic function. In this study, the smart car is divided into four modules according to the requirem -ent of self-driving---motor drive module, optical encoder velocimetry module, liquid crystal dis -play module and remote control circuit module. This paper introduces in detail the basic functio -ns and design methods of each module, and completed the production and debugging of hardw -are in each module. Finally, with procedures designed, it achieves the target requirements of the system. In this design, the structure is simple, easy to achieve, and the smart car is designed with a high degree of intelligent and user-friendly features and so on, which gives the smart car better ap -plication value. 
Keywords：smart car; motor drive system; optical code disc; liquid crystal display; remote control module
