A software-defined vehicle (SDV) platform is a comprehensive software and hardware architecture that allows vehicles to be upgraded and customized through software updates, rather than relying solely on hardware changes.
This means that features, functionalities, and even performance can be enhanced throughout the vehicle’s lifespan via over-the-air (OTA) updates, similar to how smartphones are updated.
The SDV platform centralizes software functions, enabling a more flexible and adaptable vehicle ecosystem.
Below is a more detailed look at this new and emerging technology.
Key concepts
Centralized architecture
SDVs move away from the fragmented, domain-specific electronic control units (ECUs) of traditional vehicles towards a more centralized architecture, where software functions are managed in a more cohesive manner.
Software-centric approach
The core functionality of the vehicle is determined by its software, allowing for continuous updates, feature additions, and performance improvements without requiring physical hardware changes.
Modular design
SDV platforms utilize a layered architecture, separating software development from hardware constraints, enabling greater flexibility and interoperability between different software components and hardware systems.
Over-the-air (OTA) updates
SDVs can receive software updates and new features remotely, without needing to visit a service center, enhancing the vehicle’s capabilities and addressing potential issues throughout its lifespan.
Benefits of SDV platforms
Improved user experience
Consumers can benefit from a continuously evolving vehicle with new features and improved performance over time.
Reduced development costs
Software updates can address issues and add new functionalities, potentially reducing the need for expensive hardware redesigns and replacements.
New business models
SDVs open up opportunities for new revenue streams through subscription-based services, feature-on-demand, and personalized experiences.
Enhanced safety and security
SDVs can incorporate advanced safety features and security protocols that can be continuously updated to address emerging threats and vulnerabilities.
Greater flexibility and customization
The ability to add or remove features and customize the vehicle’s behavior through software provides greater flexibility and personalization for both consumers and manufacturers.
Examples of SDV platform capabilities
Infotainment system updates
Adding new apps, features, and user interfaces.
ADAS (advanced driver-assistance systems) enhancements:
Improving safety features like lane keeping assist, adaptive cruise control, and automatic emergency braking.
Powertrain optimization
Adjusting performance parameters for better fuel efficiency or enhanced acceleration.
Remote diagnostics and maintenance
Enabling remote troubleshooting and proactive maintenance for vehicle components.
Essential software
In essence, the SDV platform represents a fundamental shift in how vehicles are designed, built, and used, paving the way for a more connected, personalized, and adaptable future of transportation.
Companies developing software-defined vehicle technology
As you might expect, all leading vehicle manufacturers have in-house teams developing software-defined vehicles technology. Some might be further ahead than others, but most have yet to launch a true SDV.
And while the automakers are busy with their own development, they might also look to bring in ideas and technologies from companies outside the vehicle manufacturing sector.
Here’s a list of companies that are not automakers which are developing software-defined vehicles.
- Bosch: A leading automotive supplier with extensive expertise in automotive software, developing integrated software platforms and cybersecurity solutions for SDVs.
- Nvidia: Provides powerful computing platforms (e.g., DRIVE Orin) and AI solutions that are crucial for enabling autonomous driving and advanced features in SDVs.
- Qualcomm.: Offers Snapdragon Ride platforms and is actively involved in promoting open-source platforms for SDVs, partnering with various OEMs.
- Continental: Developing software-defined vehicle platforms like “Automotive Edge Server” for ADAS and autonomous driving functions.
- Valeo: Expanding its expertise in automotive embedded software and offering cutting-edge applications, middleware, and services for SDV development.
- Aptiv: A global technology company focused on smart mobility solutions, including advanced software platforms for SDVs.
- Sonatus: A specialized software company providing in-vehicle and cloud software that enables automakers to achieve the full promise of SDVs, focusing on software infrastructure, data collection, and OTA updates.
