摘　　要：针对博格华纳公司生产的12V直流电机式EGR阀匹配一拖公司柴油机,基于Infineon公司推出的新一代32位单片机TC1766平台,开发系统控制软件。采用32位高性能单片机与L9958专用驱动芯片相结合的驱动方式,满足了EGR阀的控制实时性要求。通过匹配柴油机台架试验,验证了控制系统的功能。For the diesel produced by YTO Group Corporation with 12-voltage direct current electromotor EGR valve from Borgwarner company, the control software was developed based on new 32-bit single-chip microcontroller TC1766 platform. This controller was driven by combination of 32-bit high performance microcontroller and L9958 special chip. The real-time controlling requirement of EGR valve was realized. On the diesel test bench, all functions of controller were validated.
