What can an active lane-keeping assistant (LKA) do when it detects an unintended lane departure within its operating conditions?

Correct answer

It can gently correct steering to help remain within the lane.

It can gently intervene in steering to help keep or return the vehicle within the lane. Do not confuse it with LDW, which warns of unintended departure and does not itself imply active correction. Operation depends on the system and its ability to detect the road; the driver must remain attentive and in control. It does not guarantee prevention of every departure or mean automatic braking for obstacles.
