Abstract


With the implementation of increasingly stringent emissions regulations and economy of the vehicle power system reliability have become increasingly demanding requirements of automotive safety , comfort and other aspects are also rising. Traditional mechanical devices and technology in the automotive sector has matured , some of them even has reached its physical limits , it is difficult to further development . With the rapid development of electronic technology , the electronic control unit (ECU) is widely used in the car , so the car power , economy , security , comfort , reliability has been significantly improved and enhanced . Have been deployed in the high-end car 60 or more ECU , but the vast majority of these ECU foreign products , the core technology of foreign enterprises to master . R \u0026 D in China with independent intellectual property rights of automotive electronic control unit has a very important strategic and economic significance . HT5-1.1 ECU of the of Zhenjiang Hengchi Technology Co., Ltd. is a multiple - fuel engine ECU . The paper introduces the of Cikuan ECU hardware architecture , based on its hardware research and an ECU software development platform . ECU master chip peripheral interface circuit and its software development platform for software architecture . The modular design concept , design , and peripheral interface circuit in the ECU module underlying driver . ECU 's boot program and interrupt mechanism is described . Automotive electronic control units are very high requirements for real-time the ECU software uses the traditional front and back office systems to multi-task processing is difficult to meet real-time requirements . Paper embedded real-time operating system μC/OS- Ⅱ ported to the ECU to handle real-time multi-tasking and interrupt and cutting optimization transplantation μC/OS- Ⅱ system . Application layer program design method based on the ECU software development platform . In order to ensure the correctness of the software development platform , rigorous testing program designed to test the underlying drivers for the peripheral circuit module and transplantation μC/OS- Ⅱ system . Current Hengchi Technology Co., Ltd. has been successfully based on the ECU software development platform to develop hydrogen fuel engine ECU, high-pressure diesel common rail ECU variety of electronic control unit , and to ensure that emissions reach Europe - III emission standards .
