摘　　要：拖拉机动力换挡采用动力换挡技术,将传统机械传动系统替换为动力换挡传动系统。设计基于英飞凌公司推出的新一代32位单片机TC1766平台,包含A/D、GPTA和I/O模块。CAN总线通信实现对控制系统的自动标定和仪表的显示。将整个设计软件控制系统匹配一拖公司多款电控柴油机样机,以此完成了功能验证。Tractor power shift adopts power shifting technique and replaces traditional mechanical transmission system with power shifting transmission system. Design is developed based on new 32-bit single-chip microcontroller TC1766 platform,which includes A / D,GPTA and I / O module. CAN communication can actualize auto calibration of controlling system and instrument display. The whole design of software controlling system is applied in many diesel prototypes produced by First Tractor Company Limited,and all functions of controlling system are validated by experiments.
