A telematic control unit (TCU) in the automobile industry refers to the embedded system on board a vehicle that controls tracking of the vehicle. A TCU consists of: * a global positioning system (GPS) unit, which keeps track of the latitude and longitude values of the vehicle; * an external interface for mobile communication (GSM, GPRS, Wi-Fi, WiMax, or LTE), which provides the tracked values to a centralized geographical information system (GIS) database server; * an electronic processing unit; *a microcontroller, in some versions; a microprocessor or field programmable gate array (FPGA), which processes the information and acts on the interface between the GPS; * a mobile communication unit; * and some amount of memory for saving GPS values in case of mobile-free zones or to intelligently store information about the vehicle's sensor data. ==See also== *telematics 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Telematic control unit」の詳細全文を読む スポンサード リンク
