We suggest a process for the basic software configurations and application development in the mode management design of AUTOSAR-based ECU. Mode management is an essential task and AUTOSAR provides the mode management components for the runtime state handling of an ECU, such as BswM, application mode manager and RTE. BswM is used to meet the custom's requirements for ECU state handling. The behavior of BswM is configured with a set of rules in the form of "if-else" statements, so it is a complicated job and a potential source of errors as the number of rules increases. These difficulties can be overcome using the Model-Based Development approach, which is widely used in the AUTOSAR SW development. An efficient process is proposed to apply the MBD approach to the BswM configuration. An application mode development process is also proposed to improve the mode management design by combining the MBD process. Development tools are developed to adapt these proposed processes to the traditional ones. Simulation and experimental results are provided to prove the feasibility of the proposed approach.
