Investigation of a real-time communication interface between C200 and a computer
2009 (English)Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
Abstract [en]

Scania is developing a telematic unit for remote communication called Communicator 200 (C200). The purpose of the unit is to collect vehicle data and send it back to Scania. C200 is a black box hidden in the top drawer with no interaction towards the driver. Field tests are performed to verify functions in C200. Data from the tests are stored in databases in the office where it is analyzed. The loss of a driver interface makes the tests uncertain and inefficient. To simplify and make the test process more efficient an interface between C200 and the driver needs to be developed. A driver can then analyze and verify data on a computer in the vehicle during a test. This thesis is an investigation about how such an interface shall look like. Three communication interfaces and two communication protocols have been reviewed. Interviews and discussions with engineers complemented with literature studies have been the source of knowledge. The conclusion of the thesis is to use C200 extern CAN bus together with the Can Calibration Protocol (CCP) for the communication. An interface for real-time logging of parameters would make the test process much more efficient. This will reduce resources in form of saved time and human efforts.
