Abstract: With the rapid increase in the number of functions of electric vehicle controllers and software, it has become a general trend to build layered architecture to improve the scalability of products on different platforms, the safety and reliability of software, portability and life cycle. As one of theelectronic control units of electric vehicles, the motor controller has been on a par with the motor control algorithm in terms of the requirements and importance of communication and functional safety, matching vehicle architecture and adapting system characteristics. In the research on the layered architecture of motor controller software, the functional coverage was not comprehensive enough, and the layered system was not mature enough. Based on a brief analysis of the AUTOSAR concept and the layered architecture system, and analysis of the functional modules of the motor controller, the occupation of hardware and software resources and their interaction, the layering principle and the overall architecture system was put forward; The realization and description of each layer of the AUTOSAR-based motor controller software architecture of the control algorithm and functional safety module were given. the software flowchart of aspecific examples were used for analysis and explanation to verify the feasibility of the theoretical design.

Key words: motor controller, hardware/software coupling, automotive open system architecture(AUTOSAR), software layered architecture
