车辆变道智能报警装置的设计与初步实现

Intelligent Vehicle Lane-changing Warning System:Design and Implementation

针对现有车辆无法在变道前发出安全预警的缺陷,提出一种车辆变道的预警方案,并设计完成一种车辆变道的智能报警装置.车辆变道的预警方案包括实时监测车辆左右转弯灯的开启,利用超声波等探测方式来采集侧后方的车辆等障碍物,确定其相对位置,据此在驾驶员意欲变道时发出对应的声光安全预警.实验结果表明,本文技术方案易于实现,报警装置成本低廉,效果良好.

Design and implementation of a warning system for vehicle＇s lane-changing was proposed in which monitor sends out signals when driver is to tum or change lanes after detecting vehicle＇s side rear obstacle by ultrasonic, determining obstacle＇s relative position, and giving corresponding warning to the driver. Experimental results show that the technique is characterized by low cost and easy operation.
