During the development of the ASW model for automotive ECUs, the toolchain and development environment are usually configured at the early stages of the project. For instance, in the Simulink model library, even the simplest operators, such as Add, are configured to standardize the usage of various Simulink blocks among team members.As a team member, … Read more
1. Why Choose SVR for SOC Prediction? SOC prediction is essentially a regression problem — predicting the remaining battery percentage based on features such as voltage, current, temperature, and time. Support Vector Regression (SVR) performs excellently in small sample, nonlinear problems, making it particularly suitable for batteries, which are influenced by multiple factors and have … Read more
In safety-critical fields such as automotive, aerospace, and medical devices, system robustness directly determines whether products can maintain safe operation under abnormal conditions. Fault Injection Testing actively creates abnormal scenarios to verify the system’s fault tolerance capabilities. This article focuses on the technical points and implementation process of fault injection testing within the Simulink environment. … Read more
In the model-based design (MBD) process, multi-task code generation and real-time scheduling serve as a critical bridge connecting model design to hardware implementation. As the functionality of industrial control systems becomes increasingly complex, issues such as multi-rate sampling, real-time task priority management, and resource conflict avoidance have become significant development challenges. Simulink provides comprehensive support … Read more
This article demonstrates how to perform circuit simulation using MATLAB to measure the voltage of an RLC circuit. I am using R2014a, and the interface may vary slightly in different versions of the software. Open the MATLAB software and create a new Simulink Model, as shown in the figure below. After the untitled window pops … Read more
In Matlab development, the workspace is the core container for variable storage and management. Effectively utilizing the multi-workspace mechanism not only enhances the modularity of the code but also effectively avoids variable conflicts and improves program maintainability. This article systematically analyzes the types and scope rules of Matlab’s multi-workspaces, focusing on the logic of workspace … Read more
1. Background and Application Value of MBD Technology In the field of automotive electronics, Model-Based Design (MBD) has become the mainstream method for embedded system development. Compared to traditional handwritten code development, MBD achieves algorithm visualization design through graphical modeling (such as Simulink/Stateflow). Its core advantages include: – Early design verification: Algorithm logic can be … Read more
