智能汽车雷达预警系统的设计 电子信息科学与技术06-2 *** 指导教师 *** 摘要 随着我国经济飞速发展，越来越多的人拥有了自己的汽车，同时由泊车和倒车所引发的事故也越来越多。安全性是运行工具中最基率的条件，预测潜在的行车危险（如文通事故、交通堵塞等)，及时采取避碰措施，对驾驶来说是至关重要的，在当今交通状况日益恶化的情况下尤其如此。在已研制的各种用来探测车辆周围空间存在的潜在碰撞危险的汽车传感器中，雷达传感器因其性能良好及不受气候条件的影响而被看好。在汽车工业朝着智能驾驶控制方向发展的进程中，汽车雷达已成为提高汽车安全性的有效手段之一。汽车雷达能以声音或者更为直观的显示告知驾驶员周围障碍物的情况，解除了驾驶员泊车和启动车俩时前后左右探视所引起的困扰，并帮助驾驶员扫除视野的死角和视线模糊的缺陷。本文介绍了以SPCE061单片机为核心的一种低成本、高精度、微型化，并有数字显示和声光报警功能的汽车雷达系统，该汽车雷达根据超声波测距原理研制，采用优化的软硬件技术，将测得的结果送至液晶屏显示，同时进行三级声光报警。驾驶员只需坐在驾驶室就能做到心里有数，极大的提高了泊车和行车时的安全和效率。 关键词：汽车，安全性，测距技术，防撞，雷达 Intelligent design of automotive radar early warning system Electronic Information Science and Technology 06-2 *** Supervisor *** Abstract With the rapid development of Chinas economy, more and more people owned their own car, while parking and reversing caused by the accident is also increasing. These incidents are often caused so much trouble to the drivers, Security is the most basic tools to run conditions for rates to predict the potential road hazards (such as text through accidents, traffic congestion, etc.), time to take collision avoidance measures, driving is essential, in the deteriorating traffic conditions when the fortunate especially under the circumstances. Has been developed in a variety of space around the vehicle to detect the potential risk of collision exists automotive sensors, radar sensors and their performance was not optimistic about the impact of climatic conditions. Intelligent drive control in the automotive industry towards the direction of the process, automotive radar to improve vehicle safety has become an effective means. Automotive radar, also known as parking aids is a safe car parking assist device, capable of voice or a more intuitive display of obstacles around the situation told the driver to lift the driver when parking and launch vehicles around, both visit trouble caused, and to help the driver to remove the dead, and blurred vision defect. This paper introduces the SPCE061 MCU as the core of a low-cost, h
