Connected vehicle telematics service

Ericsson’s Telematics Service creates convenience, safety and security by enabling a wide range of user services for vehicle ease-of-use.

The Telematics Service is based on the generic Vehicle Data Protocol (VDP) Interface for the Connected Vehicle Cloud (CVC). The VDP Interface is used for communication between connected vehicles and the CVC for different types of data services, including telematics. The VDP Interface supports the adaptation capability when integrating with the different electric control units in the vehicle and the platform’s application programming interface ensures an efficient and rapid end-to-end integration.

Telematics Service Features

Remote safety

Remote safety connects the call-center contact to the connected vehicle via CVC to provide emergency and breakdown calls (eCall and bCall).

The eCall protocol supports both automatic and manual emergency calls when a car accident has occurred. The information reported from the vehicle is a minimal set of data (MSD) that includes vehicle location, time of accident, direction of travel, vehicle identification number, etc.

The B-Call protocol allows the driver to call road assistance if the vehicle has broken down. During the call, the call center can gather information from the CVC or directly from the vehicle.

Remote control

Remote control sends commands to a vehicle via CVC and shares the result of the command back, once it is completed. Typically, remote control will include multiple asynchronous message exchanges from CVC to the connected vehicles.

Remote control services include: remote control inhibition, engine start/stop, climate control, seat heat, lock/unlock door/trunk, honk/flash and close/open windows/sunroof.

Remote Security

The Remote Security services allows notification and actions to occur upon suspected theft.

Theft notification allows the CVC to collect theft information reported from the vehicle and make it available for other applications.

Remote vehicle immobilization allows for the call center, or other authorities, to send a command and block the suspected stolen vehicle from starting. Remote vehicle immobilization can be operated both when the vehicle is running and when the engine is turned off.

The Stolen Vehicle Tracking, SVT, allows the call center to send a command to the suspected stolen vehicle that allows it to monitor and track the vehicle continuously.

Remote Status

Remote Status & dashboard service enables the vehicle to report measurements to the CVC based on predefined events, including ignition on, ignition off, or time intervals. Meanwhile, the user can send commands from different clients via CVC to receive an update from the vehicle.

Journey Log

The Journey Log collects, processes and stores the vehicle trip information in the CVC and makes it available for different services and applications.

Remote Diagnostic Code Handling

Remote Diagnostic Code handling provides the services of collecting, processing and visualizing the diagnostics information collected from the vehicle’s Diagnotic Trouble Codes.
