telematics control module

Telematics is an interdisciplinary field encompassing telecommunications, vehicular technologies (road transport, road safety, etc., as part of Intelligent transportation systems), electrical engineering (sensors, instrumentation, wireless communications, etc.), and computer science (multimedia, Internet, etc.). Telematics can involve any of the following:

The technology of sending, receiving, and storing information using telecommunication devices, such as a Telematic control unit, to control remote objects
The integrated use of telecommunications and informatics for application in vehicles and to control vehicles on the move
Global navigation satellite system technology (most commonly GPS) integrated with computers and mobile communications technology in automotive navigation systems, often using a GPS tracking unit
(Most narrowly) The use of such systems within road vehicles (also called vehicle telematics)
