Authors: Wang Ding and Wang Fangrong, colleagues from the Electrical and Electronic Teaching Center of Jilin University and colleagues from brother colleges in Jilin Province, based on the teaching reform practice of electrotechnics in recent years, wrote this book to improve the construction of top-quality courses and better meet the technical needs of automobile specialty.

This book not only meets the basic requirements of the non-electrical electrotechnics course issued by the electrotechnics course group of the Ministry of Education, but also adopts some novel writing methods in the content structure and knowledge arrangement, thus making this book have the following characteristics.

1. Although the textbook system of this book is still consistent with the general Electrical and Electronic Technology, in order to better meet the technical needs of automobile specialty, the following three innovative means are adopted: ① The specific content is closely combined with automobile technology. ② At the end of many chapters, a new section "Application of Electrical and Electronic Knowledge in Automobile" has been added. (3) A separate chapter on "Motor in Automobile" not only makes this book have the characteristics of the close combination of electrical and electronic technology and automobile industry technology, but also enables learners to better complete the transformation from theoretical study to engineering application. At the same time, it fills the knowledge gap of some automotive professional courses from the general "Electrical and Electronic Technology" to the automotive electronic control course.

2. The content structure of this book has been carefully arranged, especially for the characteristics of distance education and self-study exams. Before each chapter of the textbook, there are "learning requirements", so that learners can fully understand the main points of knowledge to be mastered in learning, make clear the learning objectives, and be aware of them. After each chapter, there are three sections: key and difficult questions, exercises and self-test questions. It can make learners have a deeper understanding and improvement of what they have learned, and also highlight learners' subjectivity and initiative, and further evaluate the learning effect correctly, so as to be aware of it.

3. With the continuous decrease of oil resources and the improvement of people's environmental awareness, how to make cars more energy-efficient or develop new energy vehicles such as electric vehicles has inevitably attracted more and more attention. However, there are few textbooks about the new technical content of automotive electrician and electronics. Based on the development direction of automotive electrical and electronic technology in the future, the author has compiled the electrical and electronic knowledge needed by new vehicles such as power electronic circuit, drive motor and electric vehicle drive control. This is a progress in the teaching material construction of "Electrical and Electronic Technology" for automobiles.

This book is edited by, edited by, and served as deputy editor-in-chief and presiding judge of Chen Ren. Among them are (1, chapter 2), (chapters 3, 4, 5, 6 and 7), (section 8. 1, section 8.2), Lei (section 8.3), (introduction, preface) and (introduction).

Professor Chen of Hunan University reviewed this book in spite of his busy schedule and put forward suggestions for revision. I would like to express my heartfelt thanks here.

Due to the editor's limited knowledge and time, there are inevitably some mistakes and omissions in the book. Please criticize and correct me.
