Introduction
Since the 1990s, the automotive industry has witnessed a proliferation of electronic control units (ECUs) in vehicles, driven by increasing system complexity. Features such as anti-lock braking systems, traction control, and advanced driver assistance systems (ADAS) demanded dedicated ECUs, allowing for optimization, and ensuring efficient performance and reliability.
This modular approach to ECU design facilitated easier integration of new features without overhauling the entire system, offering flexibility and cost-effectiveness in sourcing, assembly, and maintenance. Moreover, dedicated ECUs for critical functions such as braking and airbag deployment significantly improved vehicle safety and reliability by isolating these functions and reducing the risk of system failures.
