Enumeration Literals

Name Description
ECU

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.

Sensor

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

Actuator

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

CouplingDevice

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.

EnergyStorage

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

Generator

A device that can generate energy.

PowerDistribution

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

Switch

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).

Lamp

Deprecated since VEC V1.2. Use ComponentNodeType "Actuator" instead and ComponentSubType Lamp.

Relay

Deprecated since VEC V1.2. Use instead ComponentSubType Relay. 

Fuse

Deprecated since VEC V1.2. Use instead ComponentSubType Fuse. 

Ground

Defines that this ComponentNode is a grounding point.

OpenEnd

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.

OpenLink

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.

PotentialDistributor

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