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 |
