The work of preparing Inter
9、national Standards is normally carried out through ISO technical committees. Each member body interested 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 wit
10、h ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (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 technica
11、l committees is to prepare International Standards. Draft International Standards adopted by the technical committees 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
12、 the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

21、lection of compliant components interconnected in a manner that provides the intended set of functions and services. Interoperability is achieved by specifying common interfaces, signals, network messages, physical environment and power management requirements. 4.1.1 A system shall be logically or p
22、hysically separated from other vehicle subsystems in a manner that inhibits undesirable interactions with those systems while promoting interchange of pertinent vehicle data across the interfacing boundary. 4.1.2 A system shall support the capability to add or remove hardware and software components
23、 across multiple network technologies. 4.1.3 A system shall, through the use of vehicle interface and service APIs, allow the deployment of various telematics and infotainment services over the lifetime of the vehicle. 4.1.4 A system shall support a common message set across multiple wired and wirel
24、ess network technologies. 4.1.5 A system shall provide a common method of power management. 4.1.6 A system shall provide a common method of diagnostics. 4.1.7 A system shall provide a common method of interconnection. 4.1.8 A system shall provide a standard interface to the vehicles HMI. 4.1.9 A sys
25、tem shall provide a common method to identify and coordinate functional services in the system, service discovery, and power-moding mechanisms. 4.1.10 A system shall support a mechanism to recover from a non-operational state. 4.1.11 A system shall have access to a minimum set of vehicle services in
26、cluding the audio subsystem, power management and some pre-defined body control functions. 4.1.12 A system shall be configured within the guidelines and framework specified in ISO 22902-1 - system architecture. 4.1.13 A system shall maintain or enhance the safe operation of a vehicle. 4.2 Modularity
27、 The elements of an system shall have standardized interfaces so the elements can be modified, upgraded or replaced without requiring a change to the other elements in the system. 4.3 Configure-ability 4.3.1 The system shall allow a configuration to be expanded by adding or deleting additional eleme
28、nts, in combination, to achieve different content levels. It is a typical practice that vehicle systems with many features have some features as options for end customer to select. Configure-ability enables scalability, expandability, and upgradeability. Copyright International Organization for Stan

30、m require the coordinated effort by several components in a system to meet the intended performance levels of the manufacture. 4.4.1 A compliant components shall be compatible with all of the specifications related to the intended functions being provided. 4.4.2 A component placed on the network sha
31、ll be compatible with the network message set, power-moding, device discovery and physical layer specifications. A component shall not interfere with the operation of an system. 4.5 Interchangeability These elements of an AMI-C system shall be interchangeable with similar modules supplied by differe
32、nt manufacturers. 4.6 Security The AMI-C system shall provide security from several perspectives: 4.6.1 A system shall support a mechanism to prevent a malicious attack for the purpose of modifying, degrading, corrupting or otherwise intentionally disrupting normal operation by the owner. 4.6.2 A sy
33、stem shall support a mechanism to limit access to vehicle services to authorized entities. 4.6.3 A system shall support a mechanism to limit access to stored information to authorized entities. 4.6.4 A system shall support a mechanism to restrict downloads to only trusted applications. 4.6.5 A syste
34、m shall support a mechanism to prevent unauthorized wireless devices and services from accessing the system. 4.6.6 A system shall support a mechanism to protect private data during data transfer between local wired and wireless devices. 4.6.7 A system shall support a mechanism to protect data during
35、 data transfer between the system and an off-board system. 4.7 Serviceability and testing An AMI-C system shall comply with the following serviceability and testing requirements: 4.7.1 A system shall be testable and comply with diagnostics service practices in the automotive industry. 4.7.2 A system
36、 shall provide mechanisms to allow a service technician to isolate faulty components of AMI-C systems for replacement or repair. These mechanism may be off-board, on-board or a combination of these methods 4.7.3 A system shall provide the capability for a service technician to determine the configur
37、ation of a system under test by interrogating the system through a diagnostic port and to determine the services provided by the system. Services must be identified with software and/or hardware version numbers. 4.7.4 A system shall provide mechanisms to assist in testing for correct operation at th
38、e time of vehicle assembly.

39、ights reserved 4.8 Service discovery requirements The service discovery requirements for an AMI-C system include: 4.8.1 A system shall support service discovery mechanisms that identify active services available to the applications installed on the system. 4.8.2 The service discovery mechanism shall
40、 identify the services in a manner that is directly obtainable by controller running application programs. 4.8.3 The service being made available to controllers shall, at a minimum, provide the following information: name and version; features of service; device providing service. 4.8.4 The service
41、discovery mechanism shall establish the services available when the system is initially powered and each time the system is reset. 4.8.5 The service discovery mechanism shall update the list of services available when a new service is added or deleted from the system. 4.8.6 In a system with a networ
42、k, device discovery must be completed prior to service discovery. 4.8.7 If a component is capable of determining failure modes of services provided, it will, upon failure detection, remove the disabled services from the registry. 4.8.7.1 The component will restore the services to the registry when t
43、he service function is restored. 5 Architecture requirements The architecture is the framework upon which the AMI-C system is formulated and configured. This framework defines how the various components of an system are interconnected, how the system logically operates, and how the system achieves a
44、ll of AMI-Cs business and technical objectives. The key elements of the architecture are the following: vehicle interface an interface to other vehicle subsystems, information and signals; network standard network and message sets to provide data interchange and control between components; host a co
45、mputer used to execute cross-platform, downloadable application code; Consumer Convenience Access (CCA) an interface to external consumer device(s). The actual implementation and use of these elements is dependent on the requirements by the individual carmakers. However, a vehicle interface must be
46、present in a valid architectural implementation. The following are the general requirements for these key elements.
