Designing a future-ready vehicle is no easy feat. Building one, demands comprehensive knowledge of vehicle architecture, expertise in software development, and the competence to integrate both. More importantly, for such software-driven vehicles to function efficiently post- launch, the software must be regularly updated — remotely and Over-the-Air (OTA).
Shift from discrete to domain to central computing architecture: Statistics peg most vehicle architectures will support High-Performance-Computing (HPC)1 by 2030. Also, it is predicted that OEMs will establish in-house capabilities in the fields of application software, functions and services, and semiconductor know-how.2
OTA as a foundational feature of vehicle architecture: With connectivity expected to reach between USD 450-750 Bn by 20303, software-driven vehicles must be updatable for better functioning. OTA’s versatility may transform it into a data pipe for other applications and a potential channel for data monetization/revenue4 for OEMs.
Non-uniform OTA adoption rates: All OEMs today, are at different stages of the OTA adoption curve but unstinted focus remains on domain and central computing.
Figure 1- Intended benefits of OTA to Stakeholders
Though OTA accelerates building of software-driven vehicles, the market is set to grow to 79% of vehicles sold worldwide by 20255 and is compliant with cybersecurity regulations, leverages changing architecture and innovative business models, the rate of adoption is slow.
Figure 2- Common notions on OTA adoption
Figure 3- Key challenges
Since the technology to download software onto a vehicle has matured, questions today revolve around bigger issues – the application of updates, downloading correct packages, determining compatibilities with vehicle configuration, state and type, ensuring the efficacy and efficiency of the quantum of update delivered and any other implementational impact. The incessant shift toward centrally controlled architecture may make integration more software-centric, thereby, complicating abilities to anticipate, visualise and verify. Naturally then, the challenges will exceed basic software update mechanisms.
However, such hurdles may be overcome through partnerships with strong, experienced transformation collaborators. That’s where KPIT comes in.
With 20+ years of experience in software integration and expertise in vehicle architecture, KPIT is a preferred partner for many OEMs to accelerate and drive their OTA adoption.
KPIT’s OTA solution for the entire vehicle, both On-board and In-Cloud, is secure, efficient and production-ready.

Highlights of KPIT’s OTA solution:
KPIT’s OTA solution’s in-vehicle software components including the Bootloader and smaller ECUs based on Classic AUTOSAR or a POSIX operator have proven competence. With its DPDU Library in series production with European OEMs, other OTA components in series production with various mainstream passenger car OEMs, and their Cloud catering to the Asian and Indian markets for commercial vehicles, KPIT is set to transform the automotive ecosystem.
“Capable of performing full-vehicle updates, KPIT’s Over-the-Air (OTA) solution addresses domain controllers from Digital Cockpit to e-Powertrain; and has successfully updated around 8 million controllers till date. KPIT’s OTA Update technology has already powered 5+ million vehicles, with another 11+ million vehicles under contract. Bringing to the table a production- grade mature solution, in-depth understanding of vehicle and software architecture, and expertise in software integration, KPIT is a transformation partner to OEMs, helping accelerate OTA adoption.”

Strengthen, accelerate and integrate the Cloud with the Build and Configuration Management Systems: KPIT’s strength lies in in-vehicle software that supports the Infotainment segment and the Service-oriented Architecture (SoA) based on Adaptive Autosar. Of late, focus has centred on developing the Cloud to accelerate and align solutions with the requirements of next-generation complexities in Campaign and Dependency Management and now, WP.29 compliance.
KPIT is a Microsoft ‘Co-sell partner’ for its Over-the-air Software Update solution, certified and optimized to run on the Azure Cloud platform. Their OTA solution integrates Azure Services — Azure IoT Hub, Azure Storage Services, Azure’s support for Containers & Container Management Services. Key tenets — reliability, scalability, high availability and security are achieved by building on the core building blocks of Azure Platform Services.
Develop recordkeeping: When undertaken across the lifecycle of software development workflows, code maturity testing evidence, signing of packages, functional safety compliance, it will eventually feed into the impact of software updates in terms of approvals. Accelerate transition to full WP.29 Software Update Management System (SUMS)-compliant solution for OEMs.
“Flexible and strong OTA solutions are a must-have for automakers today. The increasing reliance on essential capabilities delivered purely in software and the rapid pace of change in the industry makes adopting a coherent OTA solution for all vehicle lines a decision that can no longer be deferred. The progression towards in-vehicle edge, zonal architectures, in-vehicle HPC and software-defined vehicle further amplifies this foundational need. KPIT’s comprehensive end-to-end solution for OTA provides a practical and effective way for OEMs to address this requirement while leveraging the inherent strength and security of the Azure platform.
