The Next Big Evolution in Transportation

The Next Big Evolution in Transportation

Software, Cloud, and Service-oriented vehicle architectures with heterogeneous computing are revolutionizing vehicle development. While new-age OEMs are capturing the market with superior software technology, rapid innovation is expected from legacy OEMs and Tier-1 suppliers to adapt to automotive solutions that are digitally native, sustainable, secure, and reliable. 

Software-Defined Vehicles (SDVs) will create new revenue streams from applications and services for OEMs. With an always-learning AI, multiple ECU consolidations, and software updates, and robust cybersecurity solutions, we will move to a world where a car is the outdated version of itself when purchased.  With continuous automotive software upgrades, it will get better and more enriched. 

TETHER by Tata Elxsi, serves as a base Connected Vehicle Platform (CVP) for Data Collection, Over-the-air updates, cloud computation, and generating new revenue streams for OEMs through on-demand application services. Through our classic and adaptive AUTOSAR stack coupled with automotive cybersecurity product readiness, we are helping global OEMs realize their vision of Software-Defined Vehicles.
