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

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.
