摘 要
汽车历经100多年的发展，由原始汽车变化成为一个高科技的结晶体。特别是电子技术、电脑技术的飞速发展，使汽车的高科技化程度不断得到提高。电子燃油喷射系统的应用，ABS ，防抱死制动系统、SRS安全气囊系统、电子控制自动变速箱系统、空气悬挂系统、动力转向系统、自动巡航系统、中控门锁及防盗系统、动力牵引系统、自我诊断系统……，这一系列高新技术，不断完善着汽车的性能，展现在我们面前的汽车再也不是一个简单的四轮交通工具，再也不是被人讥笑为“笨重的怪物”；而是一个集现代文明和智慧的高科技产物，而这个高科技产物，还在不断地向高科技领域纵深发展。 
这种汽车自身的高科技特征，加上先进技术的不断采用，多种系统的不断发展，使得广大汽车维修技术人员对汽车电路维修信息方面的需求越来越强烈。因此汽车电路图已成为汽车维修人员必备的技术资料。正确识读汽车电路图，需要一定的技巧。电路图是了解汽车电气系统工作时使用的重要资料，了解汽车电路的类型及特点，各车系的电路特点及表达方式，各系统电路图读法、规律与技巧，指导读者如何正确识读、使用电路图有很重要的作用。

ABSTRACT
The development of the car after 100 years, the original auto change into a high-t ct. Especially the electronic technology, computer technology rapid development, that the car continuously improved high tech level. The application of electronic fuel injection system, ABS, ABS, SRS airbag system, electronic control automatic transmission system, air suspension system, power steering system, automatic cruise system, central control locks and security system, dynamic traction system, self , this series of high-tech, and constantly improve the performance of the car, show in front of us car is not a simple four-wheel transportation, no longer being laughed at for "heavy monster"; But a collection of modern civilization and wisdom of high-tech products, and this high-tech product, also continues to high-tech areas further development.
This car own tech characteristics, plus the continuously adopts advanced technology, a variety of system development, make broad vehicle maintenance technician for car circuit maintenance information needs more and more intense. So car diagram has become the necessary technology car maintenance personnel data. Correct circuit diagram, need certain car starts the skills. Circuit diagram is understanding the automobile electrical system work with important material, understand the type of car circuits and their characteristics, the circuit characteristics and the larger super cars to express way, each system diagram method, regularity and conversational skills, guidance readers how to correctly use circuit starts, very important role
