汽车电子化是七十年代以来迅速发展的一项新技术,它的发展有其一定的工业技术基础和社会背景。从技术上看,汽车电子控制技术的研究和应用,早在五十年代即已开始,随着电子技术的发展,经历了电子管、晶体管、集成电路到微处理机控制这一过程。在五六十年代,由于受当时电子器件等的限制,研制的电子控制装置体积大,可靠性差,价格贵,不能实现复杂 Automotive electronics is a new technology developed rapidly since the seventies, its development has its own industrial technology foundation and social background. From a technical point of view, the research and application of automotive electronic control technology began as early as the fifties. With the development of electronic technology, it has undergone the process of tubes, transistors and integrated circuits to microprocessor control. In the fifties and sixties, due to the limitations of electronic devices and so on at that time, the developed electronic control device was bulky, poor in reliability, expensive and could not be complicated
