Abstract: The development of core controller software for new energy vehicle is an important field of automotive electronic technology, which directly affects the performance and safety of new energy vehicle. AUTOSAR architecture is an open standard software architecture for automotive controllers, which has the characteristics of layered model, component-based design, development methodology and tool chain, and can improve the reusability, scalability, interchangeability and reliability of software. This paper takes the battery management system (BMS) of new energy vehicle as an example, and introduces the software development process and method based on AUTOSAR architecture. Firstly, it outlines the basic concepts and features of AUTOSAR architecture, as well as its application and development trend in the field of new energy vehicle; secondly, it analyzes the functional requirements and performance indicators of the battery management system of new energy vehicle, as well as the design and implementation of software components and runnables based on AUTOSAR architecture; finally, it introduces the simulation verification and performance evaluation of the battery management system of new energy vehicle, and looks forward to the future development of the core controller software development method based on AUTOSAR architecture for new energy vehicle.
