179.1 Actors
The actors associated with this scenario are as follows:
| Actor | Description | Type | Depiction |
|---|---|---|---|
ego |
Vehicle under test | vehicle |

179.2 Prerequisites
The vehicle_cut_in scenario requires a road with at least two lanes in the same direction. The Ego and the vehicle_actor must not start in the same lane.
179.3 Match criteria
Interval open: The Ego and the vehicle_actor are in different lanes, going in the same direction. The latter vehicle remains in a range of min_distance_from_sut_in_time_units and max_distance_from_sut_in_time_units from the Ego.
- Interval close: When the vehicle_actor is ahead of and in the same lane as the Ego.
- Preconditions:
179.4 Scenario phases
The phase descriptions are as follows:
179.4.1 init_drive
Ego: The Ego drives in one lane, in the adjacent lane to the vehicle_actor.
vehicle_actor: The vehicle_actor drives at the adjacent lane, ahead of the Ego and remains in a range of
min_distance_from_sut_in_time_units and max_distance_from_sut_in_time_units from the Ego during the entire phase.
179.4.2 change_lane
Ego: The Ego drives in one lane, behind the vehicle_actor.
vehicle_actor: The vehicle_actor changes lane to the Ego's lane, ahead of the Ego and remains in a range of
min_distance_from_sut_in_time_units and max_distance_from_sut_in_time_units from the Ego during the entire phase.
179.4.3 post_phase
vehicle_actor: The vehicle_actor in the same lane during the entire phase.
