新型基于激光雷达的主动防撞系统

New Active Collision Avoidance System Based on LIDAR

为解决传统主动安全控制系统人机交互性能较差的问题,提出了一种全新的基于SICK LMS151激光雷达的主动防撞系统。该系统采用Freescale MC9S08DZ60单片机为中央处理器,具有双执行模式的特点,既可自身处理数据并控制执行器执行预定操作,也可作为网关将数据结果通过USB端口有线传输和无线Wi Fi信号两种传输方式上传到上位机进行处理,并支持用户远程警戒参数配置。实验表明,该系统较好地解决了主动安全系统人机交互性较差的问题,增强了主动安全控制器与用户的互动性。

Traditional active safety system＇s man-machine interaction function has poor performance,to solve this problem,we provide the system which is based on Freescale MC9S08DZ60 MCU. It provides dual execution modes,specifically,it can process the data from LIDAR and control the actuators independently. It can also upload the data to a host computer through a USB cable or WiFi signal as a gateway. It also allows the operator to configure thevigilance parameters of the system remotely. This system basically solved the problem of the low man-machine interaction and increased the interactivity between users and the active safety system.
