22、4-6:2015(E)IntroductionThis International Standard supports and facilitates the communication between electronic control units and a tachograph. The tachograph is based upon the European Council Regulation (EC) No 561/20063and (EEC) No 3821/854as last amended.The digital tachograph concept is based
23、upon an RU storing data, related to the activities of the various drivers driving the vehicle, on which it is installed.During the normal operational status of the RU, data stored in its memory are accessible to different entities (drivers, authorities, workshops, transport companies) in different w
24、ays (displayed on a screen, printed by a printing device, downloaded to an external device). Access to stored data is controlled by a smart card inserted in the tachograph.In order to prevent manipulation of the tachograph system, the speed signal sender (motion sensor) is provided with an encrypted
25、 data link.A typical tachograph system is shown in Figure 1.Key1 positive supply2 battery minus3 speed signal, real time4 data signal in/outFigure 1 Typical tachograph systemvi ISO 2015 All rights reservedBS ISO 16844-6:2015ISO 16844-6:2015(E)This part of ISO 16844 has been established in order to e
26、nable the implementation of unified diagnostic services on CAN and on K-Line.To achieve this, it is based on the Open Systems Interconnection (OSI) Basic Reference Model specified in ISO/IEC 7498-11and ISO/IEC 10731,2which structures communication systems into seven layers.

29、BS ISO 16844-6:2015BS ISO 16844-6:2015Road vehicles Tachograph systems Part 6: Diagnostics1 ScopeThis part of ISO 16844 defines diagnostic communication and services for tachograph systems of road vehicles. The communication is specified both for CAN communication mode and K-line communication mode.
30、The diagnostic services based on ISO 14229-1 and most services are common for the two communication interfaces. Interface specific implementations are specified in the respective sections.2 Normative referenceThe following documents, in whole or in part, are normatively referenced in this document a
