中文摘要：
设计采用四块单片机（两片SPCE061A，一片AT89S51和一片AT89C52）作为电动汽车的数据采集，处理和控制核心， 实现了汽车自动行驶；判断并自动躲避障碍，选择正确的行进路线；实时自动记录并显示行驶路程；汽车倒车雷达；汽车万年历；温度的精确检测以及判断司机是否酒后驾车等功能。提出了GPS（全球卫星定位系统）方案。加入语音识别以及语音播报等功能，使得系统具有了智能化、人性化的特色。简易MTV，车牌号和车轮上七彩灯的设计，增强了系统的艺术性和趣味性。GPS（全球卫星定位系统）方案的提出则使系统具有了更强的可扩展性。开关电路采用3.3V供电以及高效的PWM电路设计，提高了电源的利用率。用霍尔器件A44E对车轮转过的转数进行测量，安装方便且测量精确度高。控制电路与电源电路通过光电耦合器件进行隔离。超声波电路实现了前方躲避障碍和倒车雷达功能。用RTC芯片DS1302获得精确的时间数据。用DS18B20进行温度的测量，使得测量分辨率精确到了0.0625度。前置式照明灯,转向灯以及车尾灯的设计，使得行驶状态更加明了。采用LED和LCD双屏幕显示，达到了对不同数据的显示要求。

Title Intellective Dynamoelectric Car
Abstract：
The data that designs to adopt four pieces of automobiles with dynamoelectric machine( two slices of SPCE061A, the one AT89S51 and the one AT89C2051) conduct and actions collect, handling and controlling the core, carrying out the automobile to drive automatically; Judge to combine the au to avoid the obstacle, choose to march forward the route rightly; Solid hour automatic record combine the manifestation drive the road; The automobile reverses the car the radar; Ten thousand calendars of automobile; Whether the accurate examination and the judgment drivers of the temperature drive after drinking or not etc. function. Put forward the GPS( the global satellite fixed position system) project. Join the speech understanding and speeches reports to wait the function, making the system have the intelligence to turn, humanized special features. Seven designs of the colorful lights on the simple MTV, the license plate number and car wheel, strengthened the art and the interest of the system. The GPS( the global satellite fixed position system) project puts forward then making system had stronger can expand sex. The switch electric circuit adopts the 3.3 V power supply and efficiently of the PWM electric circuit design, raised the utilization of the power supply. Used the machine an A44E of the hoer to turned to the car wheel of turn the number to carry on the diagraph, install the convenience and measure the accuracy high. Control the electric circuit and the power supply electric circuits to match the machine piece to carry on the insulation through the light electricity. An electric circuit carries out the front to avoid the obstacle and reverse the car the radar function. The time data that acquire the precision with the RTC chip DS1302.Carry on the diagraph of the temperature with the DS18B20 make measure the resolution precision to 0.0625 degrees. Before the place type floodlight, change direction the design of the light and the car tail lamp, make drive the appearance to understand more. Adopt the LED manifestation request of the different from a screen manifestation, come to a rightness data.
