MotionWise Communication Accelerates Software-Defined Vehicles

On December 11, TTTech Auto unveiled MotionWise Communication, a new middleware platform aimed at accelerating the shift toward Software-Defined Vehicles by simplifying and standardizing in-vehicle communication. Designed for both OEMs and Tier-1 suppliers, the solution consolidates complex communication requirements across all vehicle domains into one scalable, production-ready software product.
As part of the broader MotionWise portfolio, MotionWise Communication enables automotive manufacturers to deploy ECU-level and vehicle-level communication use cases without building fragmented, domain-specific stacks. This unified approach reduces integration complexity, shortens development cycles, and supports the software-centric architectures now defining modern vehicle platforms.
MotionWise Communication for Software-Defined Vehicles
Built on modern data-centric communication standards, MotionWise Communication for Software-Defined Vehicles leverages DDS and Zenoh protocols powered by ZettaScale Technology. These protocols are designed to handle high data throughput, deterministic latency, and reliability, making them suitable for next-generation automotive applications where software coordination across domains is critical.
The middleware addresses communication demands across:

• Safety-critical and real-time vehicle functions

• Centralized compute ECUs and domain controllers

• ADAS and autonomous driving systems

• Zonal and service-oriented vehicle architectures

This flexibility allows manufacturers to standardize communication strategies while maintaining performance and safety requirements.
Scalable architecture across ECUs and compute platforms
MotionWise Communication is engineered to scale seamlessly from high-performance central compute units to resource-constrained microcontrollers. This ensures consistent communication behavior across heterogeneous hardware platforms, a key requirement for Software-Defined Vehicles that rely on distributed yet tightly coordinated software functions.
Key architectural advantages include:

• One off-the-shelf middleware for multiple vehicle domains

• Support for mixed-criticality workloads

• Compatibility with centralized and zonal E/E architectures

• Reduced software duplication across ECUs

This scalability helps OEMs future-proof vehicle platforms as software complexity continues to grow.
Safety-ready communication for next-generation vehicles
Safety remains a core requirement for software-defined architectures. MotionWise Communication is designed to support safety-certified deployments, with a DDS safety-certified stack beta planned for availability by the end of 2025. This roadmap aligns with increasing regulatory and functional safety expectations for ADAS and automated driving systems.
By integrating safety-ready communication capabilities early in the development cycle, OEMs and Tier-1 suppliers can streamline compliance efforts while accelerating innovation across vehicle software platforms.
MotionWise Communication reinforces TTTech Auto’s focus on enabling modular, software-centric vehicle development, offering the automotive industry a practical pathway toward scalable and reliable Software-Defined Vehicles.
