System Design and Algorithm Implementation of Embedded Intelligent Car

摘要

In this paper, a multifunctional intelligent model car is designed and fabricated through hardware and software. Firstly, the MK60FX512VLQ12 chip is used as the core controller, cooperated with detection modules and execution mechanisms. Moreover, the design of software is derived by fuzzy control algorithm and Speed-current double closed loop control system, to optimize their central lines by extracting effective edge data of obstructions, overtaking, corners and vehicle barriers path types, and to improve the stability and accuracy. The intelligent car is capable of detecting surrounding environments, path-selecting, decision-making and assisting driving. Moreover, different circumstances are considered to maximize practicality, such as overtaking, keeping distance between model cars, and avoiding obstacles automatically.
