445. LCA common metrics and checks
All LCA scenarios have a common set of coverage, KPIs and checks. They are defined under the top.adas_info scenario, which is a global scenario and is active during the entire execution of an LCA scenario. They are defined under $FTX_PACKAGES/adas/LCA/scenarios/common/metrics_checks/lca_top.osc
445.1 Common coverage
| Item | Unit / Type | Range | Description |
|---|---|---|---|
| ego_max_abs_distance_from_lane_center_while_lca_active | meter | [0..2], every 0.1 | Maximum lateral deviation from lane center of ego while LCA is active |
445.2 Common KPIs
| KPI | Unit / Type | Range | Description |
|---|---|---|---|
| min_road_radius_while_lca_active | meter | [50..500] every 50 | Minimum radius of the road on which ego drives while LCA is active |
| max_road_radius_while_lca_active | meter | [50..500] every 50 | Maximum radius of the road on which ego drives while LCA is active |
| ego_max_abs_lat_jerk_while_lca_active | mpspsps | Maximum absolute value of the lateral jerk of ego vehicle while LCA is active | |
| ego_average_abs_lateral_jerk_while_lca_active | mpspsps | Average value of absolute lateral jerk of ego vehicle, measured while LCA is active | |
| ego_average_speed_while_lca_active | kph | [0..100] every 10 | Average value of the speed of ego vehicle, measured while LCA is active |
| max_absolute_lateral_acceleration | mpsps | Maximum absolute value of the average lateral acceleration of ego vehicle while LCA is active |
445.3 Common checks
| Check | Default severity | Issue kind | Default threshold | Description |
|---|---|---|---|---|
| max_absolute_lateral_acceleration | error | LCA_checks | 10mpsps | Check that maximum absolute value of the average lateral acceleration of ego vehicle while LCA is active did not go above the predefined threshold. |
| ego_within_lane_bounds | error | LCA_checks | Check that ego vehicle does not get outside of the bounds of the lane it is driving on while LCA is active. |
