AUTOSAR (Automotive Open System Architecture) stands as a global collaboration between automotive and software industry leaders, dedicated to crafting and promoting a standardised software framework and open system architecture for the automotive sector.


Understanding AUTOSAR (Automotive Open System Architecture)

AUTOSAR, the Automotive Open System Architecture, is an open framework designed to serve automotive OEMs and Tier-1 suppliers in achieving several critical objectives within the automotive industry. These objectives are centered on enhancing ECU software quality, reducing development costs, and eliminating the redundancy of developing similar ECU software components for identical vehicular applications. AUTOSAR achieves these goals by presenting a layered software architecture definition.


The primary objective of AUTOSAR is to simplify the process of transferring, combining, and integrating software components throughout the entire lifespan of a vehicle. This is accomplished by standardizing and structuring the software and electronic systems used in modern vehicles.

What is AUTOSAR used for?

AUTOSAR is used to provide inherent benefits to professionals involved in managing increasingly intricate electrical and electronic systems within a vehicle. These advantages include:

  • Simplified Integration: AUTOSAR simplifies the integration of various software components and functions within a vehicle's electronic control units (ECUs), making it easier to develop and maintain complex systems.
  • Function Switching: AUTOSAR enables the switching of functions within a complex engine control network, offering flexibility and adaptability in response to changing requirements.
  • Enhanced Control: AUTOSAR provides enhanced control over the entire product lifecycle, from initial development through maintenance and upgrades, leading to more efficient and cost-effective management of automotive software.

These features make AUTOSAR an essential framework in the automotive industry for achieving software quality, cost reduction, and adaptability to evolving vehicle technology.

ECU Transition: TC27 to TC39

To upgrade the Brake Electronic Control Unit (ECU) from the 1st generation (TC27) to the 2nd generation (TC39), follow these steps:

  1. Assess compatibility and hardware requirements for TC39.
  2. Backup existing configurations and data from TC27.
  3. Install the TC39 ECU and connect all necessary components.
  4. Update firmware and software to the latest versions.
  5. Test the new ECU for functionality and compatibility.
  6. Ensure proper communication between TC39 and other ECUs in the vehicle.
  7. Perform diagnostics and troubleshooting, if required.
  8. Complete the transition and document the process.

This transition is a crucial step in improving the performance and capabilities of the Brake ECU and ensuring compatibility with the latest technologies.
