Embedded telematics: how it works, use cases and benefits for connected vehicles
Discover how embedded telematics works, the data it collects and its applications for connected vehicles and fleets.
In an automotive sector undergoing rapid technological change, the transformation of vehicles into connected objects is fundamentally redefining how companies and fleet managers run their vehicle fleets. The rise of on-board data at the heart of the electronic architecture turns a simple means of transport into a genuine source of strategic information that can be used in real time. Today, embedded telematics has become the cornerstone of modern fleet management, predictive maintenance and overall journey optimisation.
By capturing, transmitting and analysing the activity of each vehicle, this technology offers unprecedented visibility into fleet condition, driver behaviour and operating costs. A recognised specialist in embedded systems, CAN data acquisition and connected mobility, DUNASYS supports automotive and transport players in deploying cutting-edge telematics solutions, tailored to the technological requirements of today’s and tomorrow’s vehicles.
What is embedded telematics?
Embedded telematics refers to the convergence of telecommunications and computing applied to vehicles. In practical terms, this technology relies on integrating a telematics system into the vehicle to collect, process and transmit information about the vehicle and its immediate environment.
Thanks to the connectivity provided by wireless communication modules, data is collected and transmitted in real time or with a delay to central servers. This enables continuous monitoring of the vehicle, its speed, its engine parameters and its geographical position.
It is essential to distinguish a simple consumer GPS from an embedded telematics system. A conventional GPS unit merely determines geographical coordinates and shows a route. A telematics unit, on the other hand, communicates directly with the vehicle’s on-board networks. It records not only the vehicle’s location but also fuel consumption, engine health, technical alerts and driving habits. Telematics thus turns a positioning signal into a comprehensive decision-support solution for the business.
How does an embedded telematics system work?
A complete telematics system relies on an integrated technology chain made up of several interconnected hardware and software components:
Telematics unit
The telematics unit is the central element installed in the vehicle. Connected to the diagnostic port or interfaced directly with the internal electronic architecture, it continuously reads the technical parameters generated by the vehicle’s ECUs.
On-board GPS
The on-board GPS module continuously captures the vehicle’s location, instantaneous speed, heading and route travelled. It enables accurate and responsive vehicle tracking.
Mobile networks
The data collected by the unit is encrypted and transmitted remotely over mobile networks (3G, 4G, 5G or dedicated IoT networks). This connectivity ensures a smooth flow of information between the field and the servers.
Cloud platform
A cloud platform centralises and stores all the large volumes of data sent by connected vehicles. It applies analysis algorithms to process the raw data and turn it into key performance indicators.
User dashboards
Fleet managers and operations managers access reports, charts and interactive maps from user-friendly dashboards. These interfaces make it possible to manage activity, set up custom alerts and improve decision-making.
What data can be collected?
Automotive telematics offers extremely precise measurement capabilities. The variety of information collected covers the full range of operational needs:
Vehicle position
Real-time GPS coordinates, journey history, routes taken and geofence crossing detection.
Mileage
Automatic and accurate odometer readings, essential for tracking servicing, managing lease contracts or allocating costs per journey.
Driving time
Measurement of engine running time, journey durations, idling time and compliance with working-hour limits for mobile staff.
Energy consumption
Close monitoring of fuel consumption for combustion vehicles, or of state of charge and electricity consumption for electric vehicles.
Driver behaviour
Analysis of driving style through speed, harsh acceleration, heavy braking, sharp cornering and over-revving, encouraging eco-driving and road safety.
Vehicle condition
Indicators on battery voltage, tyre pressure, fluid temperatures and the overall wear of mechanical components.
Fault codes and maintenance
Immediate reporting of ECU error codes, making it possible to detect emerging faults before they lead to costly downtime.
Applications of embedded telematics
Telematics adapts to many professions across all business sectors:
Fleet management
Overall supervision of light vehicle, van or heavy goods vehicle fleets to cut costs and optimise fleet utilisation.
Car sharing
Deployment of self-service fleets with automated booking and keyless access for employees or customers.
Predictive maintenance
Anticipating breakdowns and automatically scheduling services based on the actual wear measured on the vehicle.
Logistics
Optimisation of delivery rounds, real-time tracking of goods and traceability of transport operations.
Corporate mobility
Flexible management of business travel, tracking of mileage allowances and roll-out of mobility credit schemes.
Electric vehicles
Range management, charging planning and optimisation of the total cost of ownership of electrified fleets.
Embedded telematics and fleet management
For any business manager, fleet management is a major cost item. Integrating telematics into the automotive sector transforms the way the fleet is run day to day.
By analysing vehicle position and behaviour, managers can optimise routes effectively, cutting unnecessary mileage and fuel consumption. Real-time vehicle tracking makes it possible to dispatch the nearest technician in an emergency, leading to a clear increase in productivity.
In addition, analysing driver behaviour helps reduce accidents and premature component wear. Cost savings show up directly in the fuel bill, maintenance and insurance premiums.

Embedded telematics and car sharing
Embedded telematics is the essential technology building block for developing car sharing within companies or for public services.
Thanks to vehicle booking features linked to the telematics unit, a user can book a vehicle from a mobile app. Telematics enables doors to be unlocked remotely via a smartphone or an RFID badge, removing the need to handle physical keys.
This vehicle sharing increases the utilisation rate of company cars and encourages modern collaborative mobility, while ensuring accurate tracking of the mileage driven by each user.

Embedded telematics and predictive maintenance
Moving from reactive or time-based maintenance to predictive maintenance delivers considerable financial gains for professional fleets.
Embedded telematics sends instant technical alerts as soon as a malfunction appears on the vehicle’s CAN network. This early detection of anomalies makes it possible to intervene before a major breakdown and avoid serious mechanical failures.
By scheduling interventions only when necessary, you significantly reduce unplanned vehicle downtime.
