362. Vehicle Cut Out Behind Ego evaluation scenario

In the vehicle_cut_out_behind_ego evaluation scenario, the vehicle_actor drives behind the Ego in the same lane and then cuts out to the adjacent lane.

Scenario location: $FTX/logiq/scenario_library_post_match/vehicle_cut_out/vehicle_cut_out_behind_ego

362.1 Actors

The actors associated with this scenario are as follows:

Actor Description Type Depiction
ego Vehicle under test vehicle
vehicle_actor Vehicle behind the Ego in the same lane, that moves into an adjacent lane vehicle
Figure 1: Vehicle actor cuts out behind the Ego

362.2 Scenario phases

The phase descriptions are as follows:

362.2.1 cut_out_behind_ego_start

Ego: The Ego drives in the same lane as the vehicle_actor at the start and continues to drive in the same lane.

vehicle_actor: The vehicle_actor drives behind the Ego in the same lane while maintaining an initial distance between min_distance_from_sut_in_time_units and max_distance_from_sut_in_time_units. It then initiates a lane change and completes the maneuver at the end of the phase.

362.2.2 cut_out_behind_ego_end

Ego: The Ego continues driving in the same lane.

vehicle_actor: The vehicle_actor drives in a lane adjacent to the Ego.

362.3 Parameters

Use these parameters to constrain the scenario. If you do not set a specific value, the default value will be used.

Parameter Type Description Default value
min_scenario_duration time Minimal duration of the scenario 0.5s
max_scenario_duration time Maximal duration of the scenario 30s
min_angle_diff_between_ego_and_vehicle_actor angle Minimal angle difference (in degrees) between the orientation of the Ego and the vehicle actor 0degree
max_angle_diff_between_ego_and_vehicle_actor angle Maximal angle difference (in degrees) between the orientation of the Ego and the vehicle actor 10degree
min_cut_out_behind_ego_end_phase_duration time Minimal duration of the cut_out_behind_ego_end phase 0.5s
max_cut_out_behind_ego_end_phase_duration time Maximal duration of the cut_out_behind_ego_end phase 1s
