浅谈电子技术在汽车上的应用论文

摘要

随着汽车工业与电子工业的不断发展，在现代汽车上，电子技术的应用越来越广泛，汽车电子化的程度也越来越高。汽车电子技术是汽车技术与电子技术相结合的产物。可以说，今天的汽车已经进入电子控制的时代，而这一切都依赖于电子技术的发展。国外专家预测，汽车上装备的电子装置成本将占汽车整车成本的50％以上。汽车将由单纯的机械产品向高级的机电一体化产品方向发展，“电子汽车”走向未来。

Abstract

The auto industry and electronic industry development, in the modern bus, electronic technology used more widely, automobile electronic degree more and more is also high. Automobile electronic technology is auto technology and electronic techniques. Can say, today's cars have entered the electronic control period, but it all depends on the development of electronic technology. Foreign experts predict, bus equipment electronic device cost will account for more than 50% of the auto cost. Cars will be mechanical products from pure to advanced mechtronie product direction, "electronic car" into the future.

Keywords: electronic technology device vehicle
