Research On AUTOSAR OS Specification And Implementation In μC/OS-Ⅱ

Along with the development of the car industry, and increasing ofautomobile’s functionality, the vehicle structure is becoming increasingly complex.New technology is constantly introduced to auto industry and automobile electronicsoftware system becomes complex. Automobile software development facesproblems such as application development repeatedly, difficult to transplants,growing development costs rise, difficulty of management. Many of the automobileindustry manufacturers and suppliers urgently need a vehicle electronic basicsoftware standard.Several major automobile manufacturers, suppliers and semiconductorcomponents manufacturers to set up a joint AUTOSAR organization by2003. Atpresent AUTOSAR development tools is not perfect, and most of them iscommercial implementation，or has not yet reached commercial requirements. Soresearch of AUTOSAR standard,especially OS specification，and attempting toimplement some OS objects through the μC/OS-Ⅱ and apply it to DSCU, toexplore the method to implement AUTOSAR OS specification，and this is thepurpose of this topic.In this thesis, part of the functionality of embedded real-time operating systemμC/OS-Ⅱ is improved，according to the definition of AUTOSAR OS, to meet therequirement of the AUTOSAR OS specification. Summary AUTOSAR OS taskmanagement needs, combined with features of μC/OS-Ⅱ task management, in thisthesis, the author propose two solutions to improve μC/OS-Ⅱ task managementmechanism. Two solutions meet different needs of space and time performance inthe application respectively. After studying AUTOSAR OS Schedule Table object,we reuse μC/OS-Ⅱ counter structure, to design the structure of schedule table canrealized in μC/OS-Ⅱ. Finally, the improved μ C/OS-Ⅱis experimented on DSCUplatform, to verify the correctness of the system’s function.
