Title Design and Realization of Smart car for The Eighth Freescale Cup Smart Car Content——Hardware Design of the Electromagnetic Sensor Guidance Intelligent Vehicle Control System
Abstract
Based on the eighth “freescale” cup national smart car competition and “the eighth freescale game rules”, an vehicle control system guided by intelligent electromagnetic is determined. In order to achieve the purpose of the automatic navigation walking independently, the path recognition of the electromagnetic sensor is used. Micro-controller core control module, power management module, the electromagnetic sensor module, servo driver module, motor drive module, the encoder ramp speed measuring module, detection module, man-machine interface module, wireless communication module and signal detection module is included in the hardware system. In order to ensure the stability of the car system, all the circuit of PCB is designed according to the theory of EMC. The experimental results show that the system has good performance and meets the design requirements.
Keywords: intelligent vehicle MCU electromagnetic transducer path recognition
