Title Design and Realization of Smart Car for The Tenth Freescale Cup Smart Car Contest----Hardware Design of Visual Guidence Intelligent Vehicle Control System Based The Beacon Control
Abstract
Based on the Tenth Freescle cup smart car design contest,aiming at designing a stable and high-speed intelligent vehicle，the hardware design of visual guidence smart car based on beacn control is proposed.The design consists of the following work:selection of system component,schematic and PCB design,and the adjust of car’s mechanical structure.Based on the Top-Down design method,the system is pided into the following parts:control module of MCU,power management module,motor drive module,image processing module,hunman-machine module and debugging module.After the design,every circuit module was tested.After that,The car was assembled,and the whole system test was execute.The test shows that our design scheme is achieveable.
