Virtual validation tests software in simulated vehicle environment.
Key Takeaways:
The rise of software-defined-vehicle recalls highlights the growing complexity of automotive systems and the need for advanced testing methods.
Virtual vehicle validation offers a cost-effective solution for detecting issues earlier in the development cycle.
Challenges such as real-time performance, integration and scalability hinder the widespread adoption of virtualized testing environments.
The future of software-defined vehicles depends on overcoming compatibility and validation gaps within virtual platforms.
Software has become the linchpin of modern vehicles, with an average car now housing over 100 million lines of code. While this software drives innovation, it also introduces complexities that traditional validation methods struggle to address. Virtual vehicle validation offers a new paradigm, promising earlier problem detection, streamlined development and improved safety. However, implementing this approach isn’t without its challenges.
The Problem: Delayed Detection of Software Issues
Software testing often occurs late in the product lifecycle, sometimes only after developing physical prototypes. This delay increases the risk of discovering critical flaws during production or, worse, after the vehicle reaches the market. Software-related recalls have risen sharply, accounting for 42% of all vehicle recalls in 2024 – up from just 15% in 2023 – and affecting millions of vehicles.
Automakers recognize the need to “shift left,” addressing issues earlier in the development cycle. However, creating a complete in-vehicle environment for early-stage testing remains challenging, given the reliance on physical hardware prototypes. The solution lies in virtualization, where software can be tested in a simulated vehicle environment.
Challenges of Virtual Validation
While virtual vehicle validation offers exciting potential, it also comes with significant challenges that must be addressed to unlock its full value.
Bridging the Gap Between OEMs and Virtual Testing
For original equipment manufacturers, effective virtual vehicle validation requires a strategic approach to overcome these challenges. Key priorities include:
Requirement Decomposition: Breaking down high-level goals into detailed specifications ensures that every component and system is tested effectively.
Hierarchical Testing: Testing must occur at multiple levels – from system-wide assessments to individual components – using a combination of manual and automated tools.
Comprehensive Testing Environments: Virtual platforms must support simulations at varying levels of abstraction and offer traceability to link requirements to test cases. Scalability and flexibility are critical to accommodate evolving needs.
Automation: Automated test generation and execution can reduce time and ensure consistency, especially for repetitive tasks.
By leveraging these strategies, OEMs and suppliers can address the challenges of virtual validation and position themselves for success in the evolving automotive ecosystem.
What’s Next for Virtual Vehicle Validation?
While challenges remain, the potential of virtual vehicle validation to transform the automotive industry is undeniable. By addressing these roadblocks, automakers and suppliers can leverage virtual environments to deliver safer, more reliable vehicles while reducing costs and accelerating time-to-market.
Collaboration, innovation and the adoption of industry-wide standards will be key to unlocking the full potential of virtual vehicle validation technologies. As the industry shifts toward software-defined vehicles, it’s critical to prioritize tools and strategies that address current challenges and anticipate future needs.
The journey to seamless virtual validation will require effort, but the rewards – a safer, more efficient automotive ecosystem – are worth it.
