10、O 17215-1:2014ISO 17215-1:2014(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 inter
11、ested in 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
12、 Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO docume
13、nts should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives). Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsibl
14、e for identifying any or all such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents).

16、Foreword - Supplementary informationThe committee responsible for this document is ISO/TC 22, Road vehicles, Subcommittee SC 3, Electrical and electronic equipment.ISO 17215 consists of the following parts, under the general title Road vehicles Video communication interface for cameras (VCIC): Part
17、1: General information and use case definition Part 2: Service discovery and control Part 3: Camera message dictionary Part 4: Implementation of communication requirementsiv ISO 2014 All rights reservedBS ISO 17215-1:2014ISO 17215-1:2014(E)IntroductionDriver assistance systems are more and more comm
18、on in road vehicles. From the beginning, cameras were part of this trend. Analogue cameras were used in the beginning, because of lower complexity of the first systems. With increasing demand for more advanced functionality, digital image processing has been introduced. So-called one box design came
19、ras (combining a digital image sensor and a processing unit) appeared in the vehicles.Currently, the market demands such systems with multiple functions. Even different viewing directions are in use. It seems to be common sense that six up to 12 cameras in a single vehicle will be seen in the next f
20、uture. Out of this and the limitation in size, power consumption, etc. it will lead to designs where the cameras are separated from the processing unit. Therefore, a high performance digital interface between camera and processing unit is necessary.This International Standard has been established in
21、 order to define the use cases, the communication protocol, and the physical layer requirements of a video communication interface for cameras which covers the needs of driver assistance applications.The video communication interface for cameras incorporates the needs of the whole life cycle of an a
22、utomotive grade digital camera, utilizes existing standards to define a long-term stable state-of-art video communication interface for cameras usable for operating and diagnosis purpose, can be easily adapted to new physical data link layers including wired and wireless connections by using existin
23、g adaption layers, and is compatible with AUTOSAR.This part of ISO 17215 is related to the general information and use case definition. This is a general overview document which is not related to the OSI model.To achieve this, it is based on the Open Systems Interconnection (OSI) basic reference mod
24、el specified in ISO/IEC 7498-1 and ISO/IEC 10731 which structures communication systems into seven layers. When mapped on this model, the protocol and physical layer requirements specified by this International Standard, in accordance with Table 1, are broken into following layers: application (laye
25、r 7), specified in ISO 17215-3; presentation layer (layer 6), specified in ISO 17215-2; session layer (layer 5), specified in ISO 17215-2; transport protocol (layer 4), specified in ISO 17215-4, ISO 13400-2; network layer (layer 3), specified in ISO 17215-4, ISO 13400-2; data link layer (layer 2), s

28、cal (layer 1)ISO 17215-1 has been established in order to define the use cases for vehicle communication systems implemented on a video communication interface for cameras; it is an overall document not related to the OSI model.ISO 17215-3 covers the application layer implementation of the video com
29、munication interface for cameras; it includes the API.ISO 17215-2 covers the presentation layer implementation of the video communication interface for cameras.ISO 17215-4, being the common standard for the OSI layers 1 to 4 for video communication interface for cameras, complements ISO 13400-2 and
30、ISO 13400-3 and adds the requirement for video transmission over Ethernet.ISO 17215-2 and ISO 17215-3 (OSI layers 5 to 7) services have been defined to be independent of the ISO 17215-4 (OSI layers 1 to 4) implementation. Therefore, ISO 17215-4 could be replaced by other future communication standar
