摘　　要：针对换道过程存在风险性的特点,采用激光雷达与微处理器设计了车辆换道预警系统。换道过程中,车辆前后两个激光雷达对周围其他车辆进行探测,微处理器对自身车辆与周围其他车辆的相对位置关系进行判断,当识别得到存在碰撞风险时利用I/O接口向驾驶员提示危险,从而避免事故的发生。Aiming at the risk of lane change process, laser radar and micro-chip were used to design lane change warning system. During the lane change process, two laser radar which were installed in rear bumper of vehicle will detect other vehicles around own vehicle. Once the MCU estimated there will be risk of collision during lane change, lane change warning signal will be sent to the drivers in aim of accident avoidance
