The reviewed ISO 11898 standard has been completely restructured. It is now divided in two parts: ISO 11898-1 specifies the data link layer with its LLC and MAC sub-layers; ISO 11898-2 describes the high-speed MAU and MDI sub-layers. The reviewed documents has been harmonized with the C and VHDL models from Bosch, this is mainly the integration of the implementation guidelines. In addition, an optional Bus Monitoring Mode and the Time-Triggered Communication (TTC) option have been specified.

CANopen is a CAN-based higher layer protocol originally developed for industrial control systems. The CANopen specifications include different device and application profiles. CANopen networks are also used in vehicles, e.g. in buses for engine control, in public transportation for passenger information systems, and in off-road vehicles for different purposes. In opposite to other higher-layer approaches, CANopen software is first compiled and afterwards the network will be configured. In traditional vehicle networks configuration is done before compilation.

As opposed to other higher-layer approaches, CANopen software is first compiled and afterwards the network will be configured. In traditional vehicle networks configuration is done before compilation. Besides the use in a hybrid bus, CANopen is already implemented in different fork-lifts, road construction machines, as well as mining vehicles. CiA is developing device profiles for diesel engines, electronic gears, joysticks, hydraulic valves, etc. In addition, CANopen has been used in agriculture and forrestry machines and maritime applications.

J1939-based networks are used in most of the in-vehicle networks in trucks and buses and in some off-highway vehicles. In Europe, many of the super-construction manufacturers like to use off-the-shelf, price-competitive CANopen devices originally developed for other applications fields. CANopen is a standardized CAN-based application layer and profile specification. In order to standardize the gateway functionality, a CANopen standardized truck gateway profile is introduced.

J1939-based networks are used in most of the in-vehicle networks in trucks and buses and in some off-road vehicles. In addition, some off-highway vehicles such as agriculture and forestry machines and military vehicles are equipped with J1939-based networks. Because in Europe, many of the super-construction manufacturers like to use off-the-shelf, price-competitive devices originally developed for other applications fields, they like to buy CANopen-based modules. CANopen is a standardized CAN-based application layer and profile specification. In order to standardize the gateway functionality, a CANopen device profile for J1939 truck gateway is introduced.
