摘要:传感器在汽车中的应用非常重要,有了它,汽车变得不仅仅是一辆会行驶的铁皮,而是有感应的更智能的交通工具。汽车传感器的技术水平代表了这辆车的电子化技术水平,它是研究汽车电子技术的核心部分。一辆豪华的的高配轿车一般装有几百只各种类型的传感器,而一辆普通的低配汽车上只有几十个传感器,由此可见,传感器的数量和性能代表着现代汽车电子系统的性能。汽车上的传感器技术目前在国内外已经获得了高度重视,汽车的智能化电子化技术越发达,就越依赖传感器的技术水平。
本文就传感器在汽车上的应用技术进行了较全面的讨论,对汽车传感器进行了简要概括,包括它的作用和分类的介绍,并针对传感器在汽车上不同功能的应用了进行了简单原理的介绍。而本文的主要内容是介绍了三种应用在汽车上的传感器:发动机传感器、测速传感器和红外反射式雨量传感器。其中对于发动机传感器进行了简单的介绍,对基于磁敏传感器的测速装置进行了简单的设计,包括它的基本工作原理和结构组成。而对红外反射式雨量传感器的设计进行了较详细的研究,包括其工作原理,光路结构的设计和硬件电路的设计。

Application research on new type of sensor in automotive electronics industry
Abstract Sensors in the car is very important, with it, the car will e not just a travel iron, but a more intelligent vehicles induction. Automotive sensor technology represents the car's electronic technical level, it is a core part of research automotive electronic technology. High with a luxury car equipped with hundreds of ships of various types of sensors, but on an ordinary low with only a few dozen cars sensor, it shows that the number and performance of the sensor represents a modern automotive electronic systems performance. Sensor technology is currently in the car has received great attention at home and abroad, the car's intelligent electronic technology more developed, the more dependent on technology level sensors.
This article describes the application of sensor technology in the car for a prehensive discussion of automotive sensors are briefly summarized, including the introduction of its role and classification, and sensors for automotive applications in the different functions of a simple principle . The main content of this paper is to introduce the three sensors in automotive applications: an engine sensor, speed sensor and an infrared reflective rain sensor. Wherein th
