The Design of Autonomous Smart Car Used in Simulation of Vehicle Platoon

Abstract

The autonomous smart car is the foundation of physical simulation of vehicle platoon based on vehicle and road cooperation. This paper analyzed the architecture of vehicle platoon system in the case of vehicle-road cooperation, and proposed the constitution and structure of autonomous smart car control system.After analyzing functional requirement of the autonomous smart car, the paper designed the key hardware and software of the autonomous smart car. It took the microchip as the controller, and used camera and ultrasonic sensor for the lane navigation. At the same time, it used DC motor for control driving and steering,and the Zigbee technology was adopted to design the wireless communication module. The key algorithm about recognizing navigation lane and movement controlling method was proposed, including path extraction and controlling algorithms. The test indicated the autonomous smart car had a good and stable performance.
