Hardware Design of Tractor AMT Controller Based on DSP

Automatic transmission technology is applied in tractor to solve the problems that frequent shift and driving level influences tractor working efficiency and fuel economy. Based on the analysis of tractor AMT control system structure and functional requirements, the overall design scheme of tractor AMT control system is put forward in this paper. The tractor AMT controller hardware circuit which takes DSP as a core chip is designed. Besides, the main hardware circuit is simulated and analyzed. The simulation results show that the tractor AMT controller circuit module works stably to meet the requirements of tractor performance.
