How DoIP Powers Intelligent Vehicle Connectivity and Remote Diagnostics

 

Diagnostics over Internet Protocol (DoIP) (ISO 13400) brings IP-based transport to automotive diagnostics over Ethernet. In software-defined vehicles, DoIP enables high-throughput, secure communication between cloud data services (including diagnostic tools and OTA updates) and the vehicle, improving real-time data exchange and remote serviceability across the lifecycle.

High-Speed In-Vehicle Communication

DoIP provides an IP entry point to the vehicle via a DoIP gateway. The gateway routes Unified Diagnostic Services (UDS) requests to individual ECUs—many of which sit on CAN or other legacy buses—so automakers gain IP-level access to distributed systems without requiring every ECU to run an IP stack.

Cloud-Integrated Remote Diagnostics

Because DoIP rides on standard IP, it can be securely bridged to cloud backends. Vehicles and target ECUs are addressed using DoIP’s vehicle identification and logical addressing, letting cloud services interact with precise functions for fault analysis, software management, and predictive maintenance.

Working with SOME/IP

SOME/IP (Scalable service-Oriented Middleware over IP) complements DoIP by enabling service-oriented messaging and discovery among in-vehicle devices. In practice, DoIP handles diagnostic transport while SOME/IP supports distributed services and data aggregation; gateways can expose selected services to cloud applications when required.

Building Scalable, Intelligent Platforms

Together, IP-based diagnostics (DoIP), service-oriented middleware (SOME/IP), and high-bandwidth Ethernet form a foundation for scalable, cloud-integrated vehicle platforms that support faster issue resolution, safer updates, and future-ready architectures.

Real-Time Communication in In-Vehicle Networks: Why It Matters for Safety and Performance

Image
Modern cars are no longer engine-driven mechanical machines—they're also intelligent, software-based systems filled with sensors, cameras, and computers. But for all of these systems to function as they're supposed to, one thing needs to occur: in-vehicle, real-time communication. The in-vehicle network is a game-breaker here. Fast, reliable communications are the foundation of everything from life-safety features such as emergency braking to entertainment screens and parking cameras. Let's examine why that is important and how innovations such as automotive Ethernet, TSN, and delta compression enable it. What Is an In-Vehicle Network? An in-vehicle network is like a car's nervous system. It connects all the important parts— smart sensors such as IP cameras, multiple ECUs (Electronic Control Units), driver assistance or autonomous driving HPCs (High Performance Computing platforms), and information display screens —so they can talk to each other.   So, What...

Designing a Scalable In-Vehicle Network for Autonomous and Electric Vehicles

Image
The rapid evolution of chip-level architectures drives a transformative shift in how in-vehicle networks are designed for autonomous and electric vehicles. As high-performance computing (HPC) elements advance, more vehicle functions can be consolidated into fewer computing platforms.   This architectural compression supports the migration of edge-based software toward centralized HPCs, enabling a more efficient, scalable in vehicle network design that can help new capabilities for years to come.  Two dominant architectural approaches have emerged. Domain Master architectures assign dedicated HPCs to individual vehicle domains, such as powertrain, infotainment, or driver assistance systems. While effective for today's systems, Domain Master setups may struggle to scale as software complexity and data traffic grow. In contrast, Zonal architectures distribute HPCs throughout the vehicle's geography, with each zone controller managing software from multiple domains. This redu...

eSync Technology vs. Proprietary / custom Vehicle Connectivity Solutions

Image
The automotive industry is undergoing a significant transformation, with software now playing a critical role in vehicle functionality. By 2025, 90% of new vehicles are projected to require regular OTA (over-the-air) software updates to maintain optimal performance.   As vehicles grow more advanced, OTA automotive software updates are essential to keep everything from infotainment systems to safety features up-to-date. This has led to two significant solutions: eSync technology and proprietary (custom) vehicle connectivity solutions. Each approach has unique advantages, but which is the right choice for your needs? This shift towards software defined vehicles makes technologies more crucial than ever, ensuring seamless operation.   Let’s explore! How does eSync Stand Out in OTA Software? 1.      Standardization eSync provides a standardized framework that simplifies OTA software updates. Automotive manufacturers and suppliers don't have to ...
