车辆动力传动集中控制──变速箱控制系统开发

Central Control of Vehicle Powertrain──Developing of Transmission Control System

为提高车辆的舒适性，减轻驾驶员负担，实现车辆动力传动的集中控制，开发了变速箱控制系统．系统以80C552单片机为核心，开发了控制系统的软件和硬件，根据实验结果确定了主油压控制规律，最后进行了系统联机调试．实验结果表明，所设计的变速箱控制系统能够根据给定的换档控制规律适时换档和进行变矩器的解锁和闭锁控制，系统主油路油压控制合理，能够达到预期的控制效果．

To improve vehicle comfortableness, an automatic transmission control system for the powertrain control system was developed. The automatlc control system was developed using 80C552. The oil pressure control regulation was determined through the experiment. At last, the control system was tested on the test bench. The test results showed that the automatic control system worked well according to the shift schedule, the oil pressure was controlled properly, and the system could meet the design requirement.
