摘　　要：针对超声波传感器能够感知外部环境的特点,设计了具有避障功能的智能车。该系统以16位超低功耗MSP430单片机作为整个系统的主控核心,使用TCT40-16F/S超声波传感器均匀分布在智能车前方,通过主控系统处理超声波接受器传输过来的数据以及环境温度,控制电机驱动芯片L298的工作状态,从而实现智能车自动控制,达到避障的目的。对研制的智能车模型进行了实际测试,智能车能够在多障碍物环境中高速安全通过,没有擦、撞现象的发生,达到了避障的设计要求。Based on the characteristics of an ultrasonic sensor vehicle with obstacle avoidance function was designed. The 16 that can sense the external environment, an intelligent ultra-low power MSP430 microcontroller was used as the core of the system while the TCT40-16F/S ultrasonic sensors were evenly distributed in front of the intelligent car to process the data and ambient temperature that transmitted from the ultrasonic receiver through the main control system. The main system controls the working status of the motor driver IC L298, realizing the function of intelligent controlling and avoiding obstacles automatically. The actual test proves that the intelligent car moves quickly and safely in a multi- obstacle environment, meeting the design requirements.
