CAN Bus Data Logging for Fleet Management in India: AutoPi Telematics

GSAS Engineering · · 7 min read

Why CAN Bus Data Logging Matters for Indian Fleets

India’s commercial vehicle fleet, trucks, buses, construction equipment, agricultural machinery, generates vast amounts of operational data through the Controller Area Network (CAN) bus. Engine RPM, fuel consumption, brake pressure, transmission temperature, exhaust gas readings, and dozens of other parameters flow continuously on the CAN bus during vehicle operation. Capturing this data enables predictive maintenance, fuel optimisation, driver behaviour analysis, and regulatory compliance.

Traditional fleet management systems use proprietary black-box devices that extract a limited set of OBD-II parameters. These devices are closed, the fleet operator gets a dashboard but cannot access raw CAN frames, cannot add custom DBC files for non-standard parameters, and cannot run edge processing on the device itself.

AutoPi: Open Platform CAN Bus Telematics

AutoPi (Aalborg, Denmark) takes a fundamentally different approach. The AutoPi telematics gateway, available as the CAN-FD Pro for high-speed CAN FD networks, or the TMU CM4 for standard CAN, connects directly to the vehicle’s OBD-II port and provides full programmatic access to the CAN bus via SocketCAN on Linux.

Key capabilities for Indian fleet deployments:

  • Raw CAN frame access: read every CAN ID on the bus, not just standard OBD-II PIDs
  • DBC file support: import manufacturer-specific DBC files to decode proprietary CAN signals
  • Edge processing: run Docker containers on the device for local data filtering, aggregation, and alert generation
  • 4G/LTE connectivity: transmit processed data to cloud platforms over Indian cellular networks
  • AutoPi Cloud: fleet-scale device management, OTA updates, and data visualisation

Applications in India

  • Fleet operators: monitor fuel consumption, driver behaviour, and maintenance schedules across hundreds of vehicles
  • Automotive OEMs: field data acquisition for warranty analysis and product improvement
  • EV developers: battery state-of-charge monitoring, thermal management data, charging session logging
  • Agricultural equipment: tractor and harvester operational data for precision agriculture

AI Inside the Engineering Process: What Is Worth Automating, and What Still Needs an Engineer

Arm, SEGGER, Perforce and Siemens EDA have each put AI inside a step of the engineering process rather than on top of it: debug, remediation, design entry, inference on the part. GSAS sets out the position behind our coverage of each: which steps are now worth automating, and which keep a human because the cost of being wrong is a recall.

10BASE-T1S and PLCA: Multidrop Ethernet Explained

10BASE-T1S is the one member of the T1 single-pair Ethernet family that keeps a shared medium, and PLCA is the reconciliation sublayer that stops the nodes on it from colliding. This article covers what IEEE 802.3cg standardises, how the beacon and transmit opportunities schedule a cycle, the node count and segment length figures the OPEN Alliance interoperability test suite works to, and the failure modes that put a segment quietly back into contention while every link still looks up. Written by the GSAS Micro Systems engineering team in India for teams bringing up multidrop segments on the bench.

Automotive Ethernet Connectors: H-MTD, MATEnet, MQS

An ECU arrives on the bench with a connector nobody has a mate for, and the day is gone. Search the family names and you get connector product pages that describe their own part and stop there. This article puts the families side by side in one table using only what their public pages state, then makes the point those pages leave out: the IEEE link segment definition, not the connector, is what sets reach and loss limits, and shielding is a channel decision rather than a preference.
