Road vehicles — Low-speed serial data communication — Part 3: Vehicle area network (VAN)
Specifies the data link layer and the physical layer of the VAN, a communications network up to 125 kbit/s, for road vehicle application. The VAN is an access-method oriented multimaster-multislave which allows optimized request/response management by special method of handling a remote transmission request (retaining access to the medium to allow insertion of a response). Defines the general architecture of the network and the content of the data link layer, and the physical layer for transmission between different types of electronic modules on board road vehicles.
ISO 11519-3:1994 - Road vehicles - Low-speed serial data communication - Part 3: Vehicle Area Network (VAN) - specifies the data link layer (LLC/MAC) and the physical layer for an automotive low-speed serial network (up to 125 kbit/s). The standard defines a multimaster–multislave, access-method oriented network that optimizes request/response exchanges by permitting a remote transmission request with in-frame response insertion (retaining medium access to allow the responder to insert data).
ISO 11519-3 is intended for:
Стандарты, упомянутые в описании
Practical benefits include improved interoperability between heterogeneous modules (including very simple slave devices), prioritized messaging through arbitration, optimized request/response exchanges, and defined conformance tests for reliable vehicle integration.
