As vehicle functions and services increase, the complexity of todays automotive software increases. To make automotive software stable, most automotive components must support the AUTOSAR platform, a global standard for automotive software created by leading companies in the automotive industry. In addition, analysis of automotive software to meet functional safety requirements is also inevitably required of suppliers. Software FMEA is one of the widely used methods for analyzing software architecture and software failure risk. In this paper, we propose a convenient and efficient method for software analysis based on the AUTOSAR architecture. It also provides guidelines for conducting software FMEAs of AUTOSAR software and creating deliverables for software FMEA.

In this paper, we propose a typical SW architecture for motor-based smart actuators. First, the functional/non-functional requirements of the smart actuator were analyzed. Each functional requirement was mapped to AUTOSAR SW-C. HW-dependent SW-C and independent SW-C were designed separately. HW-independent SW-C is expected to be reu sable in several types of smart actuators. In addition, RTE code generation was performed using SW architecture. It was confirmed that the generated source code was applied to the actual smart actuator to satisfy the basic control performance criteria.
