A car sharing telematics unit is the core hardware inside a vehicle that makes an automated, on-demand mobility service possible. Think of it as the brain that transforms an ordinary car into a smart, connected asset you can rent with a tap on your phone.
In this lesson, we'll explain what a telematics unit does, its core functions, and why it's the most critical component for automating your operations and creating a seamless user experience.
Defining Car Sharing Telematics
A car sharing telematics unit is a device installed in a vehicle that transforms a standard vehicle into a connected, shareable asset. For you as the operator, it provides real-time data like GPS location, fuel level, and mileage. For your customer, it enables a completely keyless experience through their mobile app.
You can choose from different integration methods to install telematics in your vehicles. The first one connects the unit directly to the vehicle's internal nervous system, the CAN (Controller Area Network) bus. This network allows all of the car's electronics to communicate with each other, providing the richest data on everything from fuel levels to specific diagnostic codes.
For faster deployment, a plug-and-play device connects to the OBD (On-Board Diagnostics) port. This is a standard service port, usually under the dashboard. It offers a simpler installation process.
A third option is to use the manufacturer's built-in hardware, known as OEM telematics. This doesn't require additional aftermarket hardware but does need complex integration work.
Regardless of the method, the unit's purpose is the same: access vehicle data, convert it into operational insights, and let customers find, open, and close the vehicle via phone.
How Telematics Power the User Journey
From the moment a customer opens your app to the second they end their trip, the telematics unit creates a seamless experience. It powers every critical step, turning complexity into a few simple taps.
Making Vehicles Discoverable
By constantly reporting its precise GPS location, the telematics hardware allows users to see available cars on a map in real time. They can choose one nearby that suits their needs.
Enabling Keyless Access
When the user arrives at the car and taps "unlock" in the app, a secure command is sent to the telematics unit. The unit then instructs the vehicle's electronics to unlock the doors and deactivate the engine immobilizer. This process starts the rental period. It's the core of the on-demand experience.
For reliability in areas with poor cellular service, systems like CloudBoxx use Bluetooth as a backup. This allows the phone to communicate directly with the car.
Tracking Usage and Closing the Loop
During the drive, the telematics unit tracks the trip duration and distance traveled. This data is essential for accurate, automated billing. When the user ends the rental, the unit sends a final report, locks the doors, and makes the car available again for the next person. The loop is closed on a smooth, fully automated journey.
Enabling Data-Driven Fleet Operations
Beyond customer experience, the telematics unit provides a constant stream of data that transforms fleet management from reactive problem-solving into strategic, proactive operation.
The hardware reports critical vehicle health information to your fleet management software. It provides exact fuel levels, battery charge states, and diagnostic trouble codes, the same alerts that trigger "check engine" lights. You can schedule maintenance before small issues become serious problems.
The system creates automatic alerts when a car's battery runs low or tire pressure drops. Tasks dispatch to your street team instantly, who locate the vehicle via GPS and resolve the issue. This proactive approach increases availability, reduces maintenance costs, and keeps customers satisfied.
Key Features of a Reliable Unit
The quality of this hardware directly impacts your business success. When choosing a telematics unit, look for five essential attributes:
-
Connectivity
-
Real-time data
-
Security
-
Scalability
-
Analytics
Connectivity: Stay Connected Everywhere
A reliable unit maintains constant cellular connection, supporting multiple network types like 4G or LTE-M. For underground garages and weak signal areas, Bluetooth backup allows direct phone-to-car communication.
Accuracy: Know Where Your Cars Really Are
The unit must deliver precise GPS positioning so customers find vehicles exactly where shown. Vehicle data like mileage, fuel or battery must be correct for fair billing and efficient operations.
Security and Durability: Built to Last
The hardware protects against unauthorized access while controlling core vehicle functions. It must withstand constant vibrations and temperature changes inside a car. A reliable, secure, accurate unit is the foundation of trustworthy car sharing.
The Future: Mixed-Fleet Models
Telematics technology is evolving toward deeper integration and more intelligent capabilities. The key trend is the rise of mixed-fleet models.
More vehicle manufacturers now build telematics into cars during assembly. You can use these systems without installing additional hardware. However, this does not replace the need for aftermarket devices entirely. They offer additional features specifically for car sharing, like Damage Detection. Instead, you can build a diverse fleet using both OEM-connected vehicles and cars fitted with aftermarket telematics.
A single unified software platform processes data from both sources, giving you flexibility to add any vehicle model you choose.
