468. LKA lane hugger

In this scenario the ego (DUT) drives on the road at center of a lane. It then moves laterally to either side of the lane with respect to lateral_offset and turn_side inputs.

468.2 FRun parameters

Configuration Type Range Description
turn_side side right,left ego moving side
lateral_offset length [0..0.1]m Lateral distance from lane markings to side of ego (left_to_left,right_to_right)
duration time Time for lateral movement

468.3 Coverage metrics

Item Unit / Type Range Description
turn_side right,left The side to which ego moves
ego_lateral_offset length (m) range: [-2..2],every: 0.5 Lateral offset of the ego from the center of the lane
ego_speed speed (kph) range: [10..100], every: 10 Speed of ego when it starts to move laterally
ego_max_jerk jerk (mpspsps) range: [0..5], every: 1 Maximum jerk of ego

468.4 Checks

The check will fail if the following happens:

  • LKA was not set to 'on' throughout the scenario
  • LKA was activated even though the ego did not change lane
