Advancements in Zonal Architecture
Understanding the shift from domain-based to zonal control for weight and cost reduction.
AT-TCU-3-A-100
The telematics control unit, purpose-built for India's EV 3-wheeler ecosystem. OEM DVP-compliant, hardware-secured, and engineered for the duty cycles of daily commercial 3-wheeler operation. Reliable telematics for platforms that run every single day.
Empowering Every 3 Wheeler EV
AT-TCU-3-A-100 turns every EV 3-wheeler into a connected, trackable, and serviceable asset, built specifically for the OEMs and fleet platforms driving India's electric last-mile shift.
OEM-Ready by Design
Designed for the EV 3-wheeler market and compliant with OEM DVP requirements. Validated to the duty cycles and integration standards 3W manufacturers already test against, so it fits the platform without a redesign cycle.
Hardware-Level Security
Modem secured with Transport Layer Security 1.2 and an external Hardware Security Module. Data leaves the vehicle encrypted and authenticated at the hardware layer, not bolted on in software.
OTA-Enabled Lifecycle Management
Firmware updates delivered over the air via HTTPS and CAN. Fleets stay current without a single vehicle coming off the road for a manual flash.
Precise, Reliable Positioning
GNSS support across GPS, BDS, and Galileo via internal L1+L5 antenna, so location data stays accurate through the tight turns and dense traffic of urban 3W routes.
