9、1:2013ISO 16844-1:2013(E)ForewordISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in
10、 a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commiss
11、ion (IEC) on all matters of electrotechnical standardization.International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical co
12、mmittees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not
13、 be held responsible for identifying any or all such patent rights.ISO 16844-1 was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 3, Electrical and electronic equipment.This second edition cancels and replaces the first edition (ISO 16844-1:2001), which has been technicall
14、y revised. It also incorporates the Technical Corrigendum ISO 16844-1:2001/Cor.1:2005.ISO 16844 consists of the following parts, under the general title Road vehicles Tachograph systems: Part 1: Electrical connectors Part 2: Electrical interface with recording unit Part 3: Motion sensor interface Pa

16、ncil Regulations (EC) No. 561/20061and (EEC) No. 3821/85 as last amended.2The purpose of this part of ISO 16844 is to ensure the compatibility of tachographs from various tachograph manufacturers.The basis of the digital tachograph concept is a recording unit (RU) that stores data related to the act
17、ivities of the drivers of a vehicle on which it is installed. When the RU is in normal operational status, the data stored in its memory are made accessible to various entities such as drivers, authorities, workshops, and transport companies in a variety of ways: they may be displayed on a screen, p
18、rinted by a printing device, or 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 data link.A typical tachog
19、raph system is shown in Figure 1.Key1 positive supply 3 speed signal, real time2 battery minus 4 data signal in/outFigure 1 Typical tachograph system ISO 2013 All rights reserved vBS ISO 16844-1:2013BS ISO 16844-1:2013Road vehicles Tachograph systems Part 1: Electrical connectors1 ScopeThis part of
20、ISO 16844 gives the dimensions and tests and requirements for the performance of electrical connectors needed for ensuring the interchangeability of different components of the tachograph systems used for road vehicles in accordance with Council Regulation (EEC) No. 3821/85 on recording equipment in
21、 road transport. In particular, this part of ISO 16844 specifies the connectors used to connect the recording unit of the tachograph to the vehicle electrical wiring harness.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indisp
22、ensable for its application. For dated references, only the edition cited applies.
