Transforming Legacy Chassis Systems and Architecture for Seamless Integration into SDVs

The automotive industry is on the cusp of a revolution, with autonomous driving and software-defined vehicles (SDVs) transforming the future of mobility. However, this transformation also presents a significant challenge for Original Equipment Manufacturers (OEMs): how to transform their legacy chassis architecture to support the demands of SDVs. The traditional chassis systems, which have been in use for decades, are no longer sufficient to meet the requirements of modern vehicles, and OEMs must adapt to stay competitive.

The Challenges with Legacy Chassis Architectures

Today’s decentralized chassis architectures are characterized by tightly coupled hardware and software components, complex arbitration strategies, and high development costs. Such an architecture makes it difficult to integrate new features and technologies, leading to increased development costs and time-to-market. For instance, various components such as EPAS, steering, braking, and suspension are tightly coupled with their respective Electronic Control Units (ECUs), actuators, and software components. This tight coupling limits the flexibility and scalability of the system, making it challenging to implement new functionalities and innovations.

Unlocking the Potential of a Centralized Chassis Architecture

A centralized chassis, built on a Service-Oriented Architecture (SOA), offers a promising solution to the challenges posed by legacy architectures. KPIT’s integrated Vehicle Motion Control (iVMC) provides a well-defined methodology and reusable components, empowering OEMs to transition their legacy chassis architecture to a centralized, SDV-ready design. The iVMC framework consists of three distinct layers:

• Applications Layer
• Core Components Layer
• Vehicle Abstraction Layer

This framework enables OEMs to develop and integrate new features more efficiently. By decoupling hardware and software components, a centralized architecture allows for greater flexibility and scalability, and new features can be integrated more seamlessly.

The iVMC Advantage

By adopting the iVMC framework, OEMs can unlock the full potential of SDVs and achieve a higher level of scalability, flexibility, and innovation. Reusable components, a centralized arbitration mechanism, and an integrated motion control enable faster integration of new technologies and innovations, reducing development costs and time-to-market. The iVMC framework also enables OEMs to improve the overall performance and efficiency of their vehicles, resulting in enhanced safety, comfort, and driving experience.

Real-World Results

We’re working with multiple OEMs to help them transition to a centralized chassis architecture using our iVMC framework. One leading automaker has already seen significant benefits from our collaboration, including improved vehicle stability and reduced development costs.

Conclusion

The automotive industry is approaching a significant transformation, necessitating OEMs to adapt to maintain their competitive edge. By adopting a centralized chassis architecture, OEMs can accelerate their journey towards SDVs. With the iVMC framework, OEMs can unlock the full potential of SDVs, achieve greater scalability and flexibility, and improve the overall performance and efficiency of their vehicles.
