Abstract
An ECU (electronic control unit) for the high-pressure common-rail fuel system was designed for production.By using high performance the microcontroller MC68376 according to the modularization method and the reliability design procedure, the hardware and fundamental software of ECU were designed. The hardware was composed of MCU, power, input-output module. And the software included initialization, sampling, and outputting module. The engine bench and real truck test show that the system has powerful function, credible performance and the accurate and reliable control can be relied on.
