Road vehicles — Controller area network (CAN) — Part 4: Time-triggered communication

Road vehicles — Controller area network (CAN) — Part 4: Time-triggered communication

ISO 11898-4:2004 specifies time-triggered communication in the controller area network (CAN): a serial communication protocol that supports distributed real-time control and multiplexing for use within road vehicles. It is applicable to setting up a time-triggered interchange of digital information between electronic control units (ECU) of road vehicles equipped with CAN, and specifies the frame synchronisation entity that coordinates the operation of both logical link and media access controls in accordance with ISO 11898-1, to provide the time-triggered communication schedule.

Véhicules routiers — Gestionnaire de réseau de communication (CAN) — Partie 4: Déclenchement temporel des communications

L'ISO 11898-4:2004 spécifie le déclenchement temporel des communications des gestionnaires de réseau de communication (CAN): un protocole de communication série qui prend en charge la commande répartie en temps réel et le multiplexage, pour le besoin des véhicules routiers. Elle est applicable à la mise en place d'un échange d'informations numériques, avec déclenchement temporel, entre les unités de contrôle électronique (UCE) de véhicules routiers équipés d'un CAN, et spécifie l'entité de synchronisation des trames qui coordonne le fonctionnement du contrôle de liaison logique et du contrôle de l'accès au support, conformément à l'ISO 11898-1, pour produire un ordonnancement des communications par déclenchement temporel.

Road vehicles — Diagnostic communication over Controller Area Network (DoCAN) — Part 2: Transport protocol and network layer services

This document specifies a transport and network layer protocol with transport and network layer services tailored to meet the requirements of CAN-based vehicle network systems on controller area networks as specified in ISO 11898-1. The diagnostic communication over controller area network (DoCAN) protocol supports the standardized abstract service primitive interface as specified in ISO 14229-2 (UDS). This document supports different application layer protocols such as: — enhanced vehicle diagnostics (emissions-related system diagnostics beyond legislated functionality, non-emissions-related system diagnostics); — emissions-related on-board diagnostics (OBD) as specified in the ISO 15031 series and SAE J1979 series; — world-wide harmonized on-board diagnostics (WWH-OBD) as specified in the ISO 27145 series; and — end of life activation of on-board pyrotechnic devices (the ISO 26021 series). The transport protocol specifies an unconfirmed communication. NOTE This document does not determine whether CAN CC, CAN FD or both are recommended or required to be implemented by other standards referencing this document.

Road vehicles — Data communication between sensors and data fusion unit for automated driving functions — Logical interface

This document is applicable to road vehicles with automated driving functions. The document specifies the logical interface between in-vehicle environmental perception sensors (for example, radar, lidar, camera, ultrasonic) and the fusion unit which generates a surround model and interprets the scene around the vehicle based on the sensor data. The interface is described in a modular and semantic representation and provides information on object level (for example, potentially moving objects, road objects, static objects) as well as information on feature and detection levels based on sensor technology specific information. Further supportive information is available. This document does not provide electrical and mechanical interface specifications. Raw data interfaces are also excluded.

Road vehicles — Open Test sequence eXchange format (OTX) — Part 2: Core data model specification and requirements

This document defines the OTX core requirements and data model specifications. The requirements are derived from the use cases described in ISO 13209-1. They are listed in the requirements section. The data model specification aims at an exhaustive definition of all OTX core features implemented to satisfy the core requirements. Since OTX is designed for describing test sequences, which themselves represent a kind of program, the core data model follows the basic concepts common to most programming languages. Thus, this document establishes rules for syntactical entities like parameterised procedures, constant and variable declarations, data types, basic arithmetic, logic and string operations, flow control statements like loop, branch or return, simple statements like assignment or procedure call as well as exception handling mechanisms. Each of these syntactical entities is accompanied by semantic rules which determine how OTX documents are interpreted. The syntax rules are provided by UML class diagrams and XML schemas, whereas the semantics are given by UML activity diagrams and prose definitions. With respect to documentation use cases, special attention is paid to defining a specification/realisation concept (which allows for “hybrid” test sequences: human readable test sequences that are at the same time machine-readable) and so-called floating comments (which can refer to more than one node of the sequence). The core data model does not define any statements, expressions or data types that are dependent on a specific area of application. For the convenience of the user, the ISO 13209-2 OTX XML schema definition file (XSD) is published alongside this document.

This document specifies the diagnostic protocol data unit application programming interface (D‑PDU API) as a modular vehicle communication interface (MVCI) protocol module software interface and common basis for diagnostic and reprogramming software applications. This document covers the descriptions of the application programming interface (API) functions and the abstraction of diagnostic protocols, as well as the handling and description of MVCI protocol module features. Sample MVCI module description files accompany this document. The purpose of this document is to ensure that diagnostic and reprogramming applications from any vehicle or tool manufacturer can operate on a common software interface and can easily exchange MVCI protocol module implementations.

They are listed in Clause 4. The data model specification aims at an exhaustive definition of all features of the OTX extensions which have been implemented to satisfy the requirements. This document establishes rules for the syntactical entities of each extension. Each of these syntactical entities is accompanied by semantic rules which determine how OTX documents containing extension features are to be interpreted. The syntax rules are provided by UML class diagrams and XML schemas, whereas the semantics are given by UML activity diagrams and prose definitions.
