140.1 Scenario phases

The phase descriptions are as follows:

140.1.1 sut_laterally_encroach_in_lane

Ego: The Ego stays in the same lane at a maximum distance of max_lateral_distance from the vehicle_actor and drives at a lateral speed of at least min_lateral_speed.

vehicle_actor: The vehicle_actor drives in the same lane as the Ego, on the npc_relative_side_to_ego side of the Ego, with a longitudinal distance between a minimum of min_longitudinal_distance and a maximum of max_longitudinal_distance.

140.1.2 sut_near_npc_in_same_lane

Ego: The Ego stays in the same lane, keeping a maximum of max_lateral_distance from the vehicle_actor

vehicle_actor: The vehicle_actor drives in the same lane as the Ego, on the npc_relative_side_to_ego side of the Ego, with a longitudinal distance between a minimum of min_longitudinal_distance and a maximum of max_longitudinal_distance.

140.2 Configuration parameters

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

Parameter Type Unit Description Default value
npc_relative_side_to_ego av_side Side of the NPC relative to the Ego during the scenario (left or right) Required
min_lateral_speed speed mps Minimum lateral speed of the Ego during the sut_laterally_encroach_in_lane phase 0.15 mps
max_lateral_distance length m Maximum lateral distance between the Ego and the NPC during the entire scenario 5m
min_longitudinal_distance length m Minimum longitudinal distance between the Ego and the NPC during the entire scenario -5m
max_longitudinal_distance length m Maximum longitudinal distance between the Ego and the NPC during the entire scenario 5m

140.5 Usage

Import the post-match scenario top file and register the matcher in a match: block, overriding only the parameters you need. Any omitted parameters use the defaults listed in Configuration parameters.

The matcher is also available through the shared post-match import bundle:

  • $FTX/logiq/customers/base/osc/post_match_scenarios.osc
  • $FTX/evaluate/library/scenarios/scenario_library_post_match.osc (evaluation builds).

import "$FTX/logiq/scenario_library_post_match/adjacent_vehicles/ego_laterally_encroach_in_lane/ego_laterally_encroach_in_lane_top.osc"

# The following example imports the top file and overrides six parameters:
