T.idal: The Heart Defined by Software
With 500 million lines of code, the Harrier EV's T.idal (Tata Intelligent Digital Architecture Layer) is designed to revolutionize the automotive industry and transform it into a real Software-Defined Vehicle (SDV). Kulkarni highlights that we are now software-first rather than hardware-dominated. "T.idal's cockpit domain controller integrates infotainment, ADAS, and vehicle components to provide responsiveness comparable to a smartphone."
With the Harrier EV, the architecture makes its premiere and ushers in the era of software-defined vehicles. At its heart is a Cockpit Domain Controller, which centralizes entertainment, navigation, and vehicle controls for a smooth user experience. It is driven by high-compute Qualcomm Snapdragon CPUs and Continental processors. Notable features include "Anywhere Park Assist," which makes parking in cities simple by utilizing a 540° stitched surround view system with rim protection and underfloor visibility, as well as a precision touchpad interface that offers 15 degrees of granularity instead of the usual 45.
Additionally, the Harrier EV adds Vehicle-to-Load (V2L) and Vehicle-to-Vehicle (V2V) capabilities, which enable it to charge other EVs or power external equipment. After purchase, the car is kept up to date with regular over-the-air software updates. A totally redesigned Electrical and Electronic (E&E) architecture serves as the foundation for this, allowing T.idal's high processing demands. Although it is geared toward cost and feature relevance in smaller vehicles, this E&E arrangement is scalable and will be incorporated into Tata's future EV lineup.
