The penultimate installment in this series highlighted the importance of a DevOps cycle that connects operations and development in autonomous driving systems, with software updates ensuring the car evolves over time. As we wrap up this series, we turn our focus to the concept of the software-defined vehicle (SDV), which is reshaping the automotive landscape.

One prominent example of SDV development is the Scalable Open Architecture for Embedded Edge (SOAFEE) initiative, a collaborative effort led by companies in the automotive industry to build an open-source architecture for SDVs. In the SOAFEE architecture, software developed and simulated in the cloud is distributed to vehicles and runs directly on onboard computers.

This is what is known as a cloud-native architecture and Autoware has been selected as a reference application for SOAFEE, taking advantage of its open-source model and free availability.

According to a Japanese government report, SDVs have the following features:

• Separation of software and hardware
• Simulation environments
• Data-driven development with frequent over-the-air updates
• Continuous value addition through software updates

These features align with the themes discussed throughout this series. Here’s a recap:

• Autonomous driving technology requires continuous adaptation to evolving road environments, achieved through regular software updates that address new scenarios.
• Open-source software like Autoware enhances development efficiency and facilitates widespread technology adoption.
• Autonomous driving development involves extensive testing with computer simulations. However, the concept of safety of the intended functionality (SOTIF) remains crucial for identifying and mitigating unknown risks.
• A DevOps cycle ensures ongoing improvements by integrating real-world data, conducting simulations, and refining systems post-deployment.
• Traditionally, cars have been built with the idea that a vehicle is the safest at the time of manufacture. However, to incorporate autonomous driving capabilities, it is essential for the vehicle to evolve through software. This necessitates a change in the vehicle's architecture, signifying a shift in the importance of software over hardware, and altering the role that hardware plays in the vehicle.

In the context of autonomous vehicles, the key elements of SDVs include software installations for autonomous driving capabilities, simulation testing during the development phase, a DevOps cycle based on real-world data, and continuous over-the-air updates to enhance safety and performance.

E/E architecture for autonomous vehicles

The integration of advanced software and continuous updates is becoming increasingly critical as the automotive industry embraces SDVs. As we move towards an era where vehicles are increasingly defined by their software, the potential of SDVs extends beyond autonomous driving.

This series has explored how this shift enhances autonomous driving capabilities, paving the way for innovative mobility solutions such as robotaxis and car-sharing services. The final installment focused on the pivotal role of software-defined vehicles in the evolution of autonomous driving.
