摘　　要：现代电控机械自动变速器(AMT)控制系统中较多的控制参数、复杂的控制策略、较高的实时控制要求和恶劣的工作环境增加了其电子控制单元设计的难度。充分利用数字信号处理(DSP)芯片TMS320LF2407A高效的运算速度以及丰富的内置功能模块单元,采用模块化的软件设计方法设计AMT控制单元,提高了AMT控制系统的稳定性、实用性以及可升级换代的能力。按照装备机械式燃油系统柴油发动机的重型车辆对AMT的要求,设计开发了相应的电控单元。In the modern automated mechanical transmission （AMT） control system, many controlled variables, complex control strategies, high real-time control requirements and bad working conditions increase the difficulty of electronic control unit （ECU） design. Taking advantage of highly effective operating speed and rich embedded function module unit of digital signal processing （DSP） chip TMS320LF2407A, adopting the modularized design method, the AMT electronic control unit was designed. The stability, practicability and ability of upgrade of the ECU were improved. According to the demand of heavy-duty vehicle equipped with mechanical fuel oil system of diesel engine to the AMT, the corresponding ECU was developed.
