SystemConfigBlueprint

This file contains the possible agent modules and channels of a dynamically generated agent. The content of this file should only be adjusted by experienced users with knowledge of the simulation architecture. The SystemConfigBlueprint is a special SystemConfig and has the same schema. Only the system with id 0 is used for generating dynamic agents. If the simulation uses only statically configured agents (AgentProfile Type attribute is “Static”), this file isn’t required.

AgentComponents

All components are listed here. An agent consists of a subset of this components.

Attribute	Description
Id	Used as key by the simulation to find the component
Priority	The module with the highest priority value gets executed first by the scheduler
Offset	Delay for the trigger method of each component in ms
Cycle	Interval in which the component gets triggered by the scheduler in ms
Response	Delay for the UpdateOutput method of each component in ms
Library	Library name of this component
Parameters	Parameters used by the component

Example: This example describes the Sensor_Driver module.

<component>
    <id>SenderCar2X</id>
    <schedule>
        <priority>399</priority>
        <offset>0</offset>
        <cycle>100</cycle>
        <response>0</response>
    </schedule>
    <library>AlgorithmCar2XSender</library>
    <parameters/>
</component>

Priorities

Please refer to the Components and channel communication diagram for assignment of a proper priority. Based on the signal flow, input relevant components like sensors need to be executed first. They provide data for consuming components (algorithms) like ADAS and drivers. Data is then handled by algorithms like Algorithm_Lateral. Output-relevant modules like dynamics and actions are executed last.

Prioritizer can be applied on different levels depending on the modules/data they need to handle levels as following can be defined:

• Level 1 describes data produced by ADAS and drivers

• Level 2 describes data output by vehicle dynamic controllers

• Level 3 describes data delivered by dynamics

Priorities can be grouped (coarse) as following: Highest number indicates highest priority.

Scope	Range
Parameters	500
OpenScenarioActions	400
Sensor	350…399
Event	330
DriverMode	310
ADAS	250…299
ComponentController	200

Updater	0…24

The table below can be used as orientation when a new module is introduced.

Channel-Ids

Channels allow components to communicate with each other. The signal flow is set explicitly via a channel-Id of 4 digits (see also Components and channels communication diagram).

The first two numbers define the sending module (XX 00). The other two digits define the type of signal that is sent (00 XX).

Signals as well as modules can be grouped to allow explicit numbering (see tables below).

Channel-Ids between Sensor and SensorFusion are an exception to this rule. For sensor/sensor fusion communication channel-ids are 9900 + x (incremented for every new sensor)

Example: PrioritizerAccelerationDriver -> AlgorithmLongitudinalDriver with signal of type AccelerationSignal: 1813.

    <parameter>
        <id>StringParameter</id>
        <type>string</type>
        <unit/>
        <value>Lorem ipsum</value>

            <mean>15.0</mean>
            <sd>2.5</sd>
            <min>10.0</min>
