摘要： 针对某型装有液力自动变速器的重型载重汽车,设计了电控系统的TCU硬件电路实现方案,在其内部固化了各种控制程序,包括换挡控制、闭锁离合器控制、液力缓速器充排油控制、换挡品质控制等;采用分层、分模块方式开发了电控系统的软件。制定了重型车两参数自动换挡策略,结合台架试验,最终实现功能验证。结果表明,所设计的电控系统软硬件能够实现对自动变速箱的综合控制,并且能够改善换挡质量。

关键词: 流体传动与控制, 液力自动变速器, 控制系统, 试验验证

Abstract: The hardware circuit implementation scheme of TCU of the electric control system for a certain type heavy vehicle with hydrodynamic automotive transmission was designed. In this scheme various control procedures were cured, including shift control, lockup clutch control, filling and emptying oil of hydrodynamic retarter control, shift quality control and so on. The software of the electronic control system was developed by layered and sub-module method. Automatic shift strategy with two parameters was formulated and combined with the bench test, which finally realized the functional verification. The testing results show that the designed hardware and software of the electronic control system can realize the integrated control of the automatic transmission and improve the shift quality.

Key words: fluid power transmission and control, automatic transmission, control system, experimental verification
