Name Description

Electronic Control Unit. An electronic control unit (ECU) is any embedded system in automotive electronics that controls one or more of the electrical systems or subsystems in a vehicle.


A sensor is a device that detects changes to the environment and sends them as information to other devices (e.g. an ECU).


An actuator is a device that is responsible for controlling or moving a mechanism.


A CouplingDevice is the (virtual) device that separates / connects two or more wiring harnesses. "Virtual" because it can be interpreted as a device / interface definition between the harnesses, where one harness behaves like an E/E component form the point of view of the other harness.


A device that stores energy in some kind of way (e.g. a battery).


A device that can generate energy.


A device that distributes power to other devices (e.g. a fuse box).


A "Switch" is a device that can change its internal connectivity in reaction to some external action (e.g. connect / disconnect some pins). A switch has no "active" logic (in contrast to an ECU).








Defines that this ComponentNode is a grounding point.


Defines that this ComponentNode is the end point for some unconnected connections that require wires and routings in the resulting harness (e.g. an antenna). A component node of this type is used whenever connections shall not be connected (on one side), regardless if it is an individual wire or a core of a multi core wire.


Defines that this ComponentNode is an OpenLink. In the description of partial systems, it can be necessary to reference a ComponentNode that is not defined in the scope of the partial system (e.g. vehicle infrastructure like power, ground, bus systems). OpenLinks must be resolved and replaced by a determined ComponentNode when a partial system is integrated into a vehicle system.


A passive device that distributes one or more potentials. Splits a network into different Connections with the same Signal.
