Anatomy of the AutoSAR family: BSW's pattern management capabilities
AutoSAR is an open automotive software architecture designed to provide standardized solutions to support the development of automotive electronic systems. Among them, BSW (Basic Software), as one of the core components of the AutoSAR architecture, has many important functions. This article will focus on the mode management function of BSW, and provide relevant source code examples to deepen readers' understanding of this function.
1. Overview of model management
Schema management is an important task in automotive software development. It involves controlling the electronic system to work in different working modes to adapt to different needs and environmental conditions. The mode management function of BSW provides a mechanism for managing state migration and behavior switching of different modules. Through this mechanism, it can ensure that the system can efficiently respond to external events and internal changes, and smoothly switch between different modes.
2. Example of mode management
In order to better illustrate the mode management function, we will illustrate it with a simple example below. Suppose we have an automotive electronic system, which contains two modules: Engine Control Module (Engine Control Module, ECM) and Seat Control Module (Seat Control Module, SCM). ECM is responsible for controlling the work of the car engine, while SCM is responsible for controlling the adjustment of the seat.
In this example, we will define two modes: driving mode and parking mode. In the driving mode, the ECM needs to monitor the parameters of the engine and control accordingly, while the SCM does not need to adjust the seat. In park mode, the ECM only needs to keep the engine idling, while the SCM needs to adjust the seat.
Below is a simplified C code example that demonstrates how to use BSW's schema management capabilities to implement the above example:
