BBCU in Smart Cities applications

The article describes the architecture and use cases of the vehicles external control unit (BBCU - BODY & BOARD CONTROL UNIT) for the vehicle communication within global traffic systems including traffic security and safety (Car2Car, Car2Infrastructure concepts supported), IoT architectures as well as Smart Cities applications. The BBCU is an embedded system optionally supplemented with graphical user interface installed inside the vehicle and designed to fulfil three basic functions. The function of an event recorder storing data from sensors installed both inside and outside the vehicle. It monitors and records data of the trip and other significant events. The other function is the communication with peripheral systems installed inside the vehicle (IR cameras, RFID readers etc.). The third function is the analysis of data received from peripheral systems and transmission of data to the system eCall as under preparation and other transport applications. What has to be safeguarded for this purpose are free interfaces, computing capacity, safe and fast data storage.
