摘  要:
An automatic shift control system, including hardware and software, has been developed in this paper for the purpose of realizing automatic control of a vehicle equipped with hydro mechanical transmission during shifting. The configuration and the design method of the system were described. Design principle of the input module, such as pulse data, analog signals and on off value, and the output module were investigated. Utilizing the idea of modularizing design and the control technology of real time and multi task, the control software was designed, which can be extended and regrouped easily due to it's focus on the interrupt control. PC monitor software has also been designed to inspect and control the system. To validate the design, a simulation test was tried out. The testing results showed that the principle of automatic shift control system was correct and the technology available.
