摘要： 提出一种基于2个6缸柴油机电控单元构成主-从电子控制单元( Electronic Control Unit, ECU)的控制系统，实现对12缸电控单体泵机车柴油机控制.主、从ECU具有完全相同的软、硬件结构，由ECU所在控制系统中的物理位置决定其主、从身份，两者具有完全可互换性.阐述了主、从ECU的硬件结构、身份识别逻辑、通信协议以及发动机控制策略，并将设计的系统应用于12V280机车柴油机.实验证明，所提出的控制系统设计合理，各实验工况转速稳定，误差可以控制在0.5%以内.

Abstract: This paper presented a master-slave electronic control unit (ECU) control system of diesel engine based on two 6-cylinder engine control units, which implements control on a 12-cylinder locomotive diesel engine. The master and slave ECUs have the same hardware and software architecture, and the identification of master or slave ECU only depends on their physical positions, therefore they have fully interchangeability. The paper described the hardware architecture, the logic of status identification, the communication agreement and engine control strategy of the master-slave ECU. The results of experiments prove the rationality of the control system. The 12V280 locomotive engine works well and the speed is stable in experimental conditions, as well as the errors can be controlled within 0.5%.

Key words: master-slave electronic control unit, diesel engine, control system
