Class LongitudinalDistanceAction

Applied Stereotypes:
XSDcomplexType
Implements Interfaces:
MotionControlAction

This action activates a controller for the longitudinal behavior of an entity in a way that a given distance or time gap to the reference entity is maintained.
The target position may be either on the same road segment where the reference entity is positioned or on a connecting road. In the latter case for coordinate systems lane and road, the distance or time gap is calculated along the road reference line / lane centerline of the connecting road. It is assumed that the reference line of the road / lane centerline of the reference entity continues seamlessly on the connecting road (even if its shape changes). It is assumed that the target position relates to the routing of the reference entity. Otherwise, the calculation of the target position cannot be interpreted within the OpenSCENARIO standard.

Properties
  Name Type Cardinality AppliedStereotypes Description
  continuous boolean 1..1 XSDattribute If false, the action ends when the target distance is reached. If true it does not end and can only be stopped.
  coordinateSystem CoordinateSystem 0..1 XSDattribute Definition of the coordinate system to be used for calculations. If not provided the value is interpreted as "entity". If "entity", the coordinate system is interpreted as the actor's local coordinate system.
  displacement LongitudinalDisplacement 0..1 XSDattribute The displacement in which the distance or time gap applies. Where omitted, 'trailingReferencedEntity' is assumed.
  distance double 0..1 XSDattribute Distance value, not to be used together with timeGap attribute. Unit: [m]. Range: [0..inf[.
  entityRef Entity 1..1 nameRef, XSDattribute Reference entity the distance shall be kept to.
  freespace boolean 1..1 XSDattribute True: Distance is measured using the distance between closest bounding box points False: Reference point distance is used.
  timeGap double 0..1 XSDattribute Time gap value, not to be used together with distance attribute. Unit: [s]. Range: [0..inf[.
  dynamicConstraints DynamicConstraints 0..1 XSDelement Parameter that assigns either unlimited dynamics (if ommitted) or limited maxAcceleration/maxDeceleration/maxSpeed to the action.
