汽车电控自动变速器的结构原理与检修

The structural principle and maintenance for automobile electronically-controlled automatic transmission

随着电子技术及微处理机的发展,电控自动变速器正实现一机多参数多规律控制,并在此基础上将变速器微机和发动机微机合并在一起,实现综合控制。电控自动变速器变速冲击小,采用最佳的经济性和动力性换档,大大地改善了整车性能。介绍了电控自动变速器的控制原理、基本组成及其部件的工作原理以及性能检测方法和故障诊断方法。

With the electronic and microprocessor technology development, electronically-controlled automatic transmission is a mechanism to achieve more multi-parameter control laws, and on this basis, the transmission and engine computer PC combined to realize the comprehensive control. Electronically-controlled automatic transmission servers as less spead impact and economical and powerful shift, which greatly improve performance. The electrically-controlled automatic transmission control theory is discussed including the working principle and its components, detection methods, performance and fault diagnosis.
