How Does a Telematics Device Work?

From receiving GPS information to engine interface, telematics works wonders in the vehicle industry. Learn about how Telematics devices work in EVs.

We all know that the Automotive industry is a billion-dollar industry with a CAGR (Compound Annual Growth Rate) of at least 8%. Similarly, the EV industry is also booming, with a whopping 25% CAGR in India. 

But what makes all of this so technologically evolved? It’s definitely the autonomous driving features, connectivity (IoT), and telematics that make it grow more.

In this article, let’s understand how a telematics device works, especially in an EV.

A telematics device combines informatics with telecommunications to collect car data, such as position, speed, and diagnostics. It helps with theft recovery, vehicle health monitoring, insurance pricing based on driving behavior, and fleet management. These gadgets are essential for improving efficiency and safety since they transmit data via cellular and GPS technologies. The main question is, 

How Does a Telematics Device Work?

A telematics device utilizes GPS for location tracking, sensors for data collection (speed, diagnostics), and cellular networks for data transmission. It sends vehicle information to a central system, enabling real-time monitoring, fleet management, and performance analysis.

Let’s take a closer look at the main components of the telematics system.

Basic Components of Telematics Device System

A few basic components in a telematics device system enable real-time monitoring and provide information to a central system. Let’s see what they are.

  • Vehicle tracking device: Usually consists of sensors and a GPS receiver to gather information about the vehicle, such as miles, speed, and diagnostics.
  • Data Transmission: Transfers gathered data securely to central servers or cloud-based platforms via satellite or cellular networks.
  • Data Reception: Central servers or cloud-based systems receive and store transmitted data for real-time fleet and vehicle monitoring, analysis, and remote management.

Now that we've covered the basics let's explore how these telematics devices gather, transmit, and store all that crucial data.

Data Collection, Transmission, and Storage in Telematics Device System

Advanced technology is used by telematics systems to gather precise information about driving habits and car location.

Let’s learn more about how data works in telematics device systems.

  1. Sensors and Data Gathering

Telematics device units are fitted with various carefully positioned sensors in many regions of the vehicles. These sensors keep an eye on several different characteristics, including:

  • Speed: Monitoring the live speed of the car.
  • Accumulation and Deceleration: Quantifying the speed at which the vehicle increases or decreases.
  • Braking Patterns: Frequency and severity of braking are recorded.
  • Engine diagnostics: Tracking parameters related to engine performance, like RPM, temperature, and fuel efficiency.

These sensors collect data continually while the car is being driven, giving a complete picture of the driver's style and vehicle state.

  1. GPS Technology

The Global Positioning System (GPS) is essential to telematics because it precisely determines the vehicle's location. Coordinates for latitude, longitude, and altitude are obtained via satellite communication between the telematics device and satellites' GPS receivers. Since this data is updated often, tracking vehicle movements in real-time is made possible.

Fleet managers can use this data to monitor vehicle movements, plan more efficient routes, and enforce operating boundaries with geofences. Historical tracking capabilities offer insights into past routes and driver behavior, making performance analysis and compliance monitoring easier. GPS integration with other telematics data benefits businesses from construction to logistics by enhancing asset tracking and operational control, improving safety through quick emergency response.

  1. Data Storage: Centralized Storage and Analysis

Integration with analytics tools enables visualization and reporting of key performance indicators (KPIs), aiding decision-making. Centralized systems ensure data security and regulation compliance and facilitate rapid emergency response. Scalable infrastructure accommodates expanding fleets and growing data volumes, ensuring continuous improvement in fleet management, safety, and operational effectiveness across various industries.

Regarding temporary data, recent operational data is temporarily stored in a vehicle's telematics device before being transmitted to centralized systems. This storage device provides real-time position, speed, and diagnostic data. This provisional storage guarantees data continuity during connectivity failures and enables smooth data transfer when communication is restored.

  1. Data Transmission

Telematics data transmission uses networks like GPRS, 4G, or satellite to transfer real-time vehicle data, such as position, speed, and diagnostics, from onboard equipment to centralized computers. 

Thanks to this constant flow of information, fleet managers can guarantee timely maintenance, optimize routes, and monitor fleet activities. It facilitates proactive decision-making by offering insights into driver behavior and vehicle performance. 

Data integrity and confidentiality are ensured during transmission through secure communication protocols, which is crucial for compliance and operational effectiveness in all sectors of the economy that depend on fleet management and logistics.

Now, let's move on to how to install these telematics devices in vehicles properly.

Installation of Telematics Devices

Installing telematics devices involves considerations of vehicle compatibility, installation methods, and functionality, especially when integrating into the OBD-II port or considering pre-installed versus aftermarket options:

  1. Guide for Installing OBD-II Ports

Installing telematics devices usually involves using the OBD-II (On-Board Diagnostics) port on the car, usually found under the dashboard. This connector supplies electricity to the gadget and offers direct access to diagnostic and operational data from the car. Usually, the installation procedure entails:

  • Finding the OBD-II Port involves locating the port beneath the dashboard, which is typically close to the driver's side.
  • The first step in connecting the telematics device is firmly inserting it into the OBD-II port. It is important to ensure the gadget doesn't block or interfere with the driver's other controls, such as the pedals.
  • Safeguarding the Link: establishing a solid and steady connection to avoid dislodgement when driving a vehicle.

OBD-II ports' data transfer methods (such as the CAN bus) are standardized, making integrating with the car's internal systems easier.

  1. Pre-installed vs Aftermarket Installation Options
  • Pre-installed Telematics Systems: A few cars have telematics systems fitted from the factory. During production, these systems are seamlessly integrated into the car's design, offering features like GPS tracking, remote diagnostics, and vehicle status monitoring. However, they might just provide a few choices for personalization.

  • Aftermarket Telematics Devices: Aftermarket devices offer freedom for cars without factory-installed systems. Usually, these gadgets work with many car makes and models. Considerable elements include:
  1. Compatibility: Verifying that the gadget complies with the car's power and OBD-II protocols (such as the CAN bus).
  2. Functionality: Evaluating attributes such as GPS tracking, data transfer (GPRS, 4G), and software integration for fleet management.
  3. Installation Expertise: Professional installation skills may be needed, particularly to guarantee correct positioning, safe connections, and adherence to vehicle-specific instructions.
