320.1 Scenario phases

The phase descriptions are as follows:

320.1.1 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.

320.1.2 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.

320.2 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
npc_relative_side_to_ego av_side The side of the NPC relative to the Ego during the scenario (left or right). There is no default value, the user must provide a value.
min_lateral_speed speed The minimum lateral speed of the Ego during the sut_laterally_encroach_in_lane phase. 0.15 mps
max_lateral_distance length The maximum lateral distance between the Ego and the NPC during the entire scenario. 5m
min_longitudinal_distance length The minimum longitudinal distance between the Ego and the NPC during the entire scenario. -5m
max_longitudinal_distance length The maximum longitudinal distance between the Ego and the NPC during the entire scenario 5m

The input items inherited from the sut.logiq_base_vehicle_scenario scenario are as follows:

Parameter Type Description Default value
kinds list of evaluation_object_kind The possible kinds of vehicle_actor in the scenario No default value
