Abstract: This paper explains the importance of life cycle management from the perspective of the development of future automotive controllers, analyzes the limitations of traditional controller life cycle management solutions, clarifies the requirements for domain controller life cycle management under the MCU+GPU system architecture, and proposes a domain controller life cycle management solution compatible with Linux operating system. At the same time, it analyzes the faults reaction strategy and designs the software architecture of life cycle management. Finally, the performance of actual software running under this design is given.

Keywords: domain controller; life cycle management; stability; robustness
