Lane Assist And Centering Control Description And Function: Components
Technical Description:
The lane assist and centering control is integrated in the ADAS functions. It contains the following functions:
- Lane departure warning (LDW)
- Lane keeping assist (LKA)
- Emergency lane keeping (ELK)
These three systems are functionally interdependent. Lane Departure Warning serves as the basis. Lane Keeping Assist and Emergency Lane Keeping each extend the functionality of the subordinate system.
You can activate "Lane Assist" in the "Driving Assistance" menu. You can also choose the acoustic signal (chime) the system emits as a warning. You can use the "Responsiveness" button to set the sensitivity level of the system.
Lane Departure Warning (LDW) can only be issued once the vehicle has crossed the "earliest warning line" into the "warning zone" and the vehicle unintentionally drives beyond the "earliest keeping line" into the "intervention zone". LKA can provide active steering control to keep the vehicle in its original lane.
Emergency Lane Keeping (ELK) can also provide steering intervention whenever an oncoming or overtaking object/vehicle is detected when the vehicle is unintentionally drifting into the ELK keeping zone.
The "earliest keeping line" is affected by lane width, vehicle dynamic status and road condition. The "earliest keeping line" of Emergency Lane Keeping (ELK) can be calibrated. When the vehicle is in a curved lane, the "earliest keeping lines" on both sides will move to the inner side of the curve. The "earliest warning line" and the "latest warning line" are both parameters in the control unit.
