Lane Departure Warning (LDW) - limitations

Lane Departure Warning is one of the functions in the Driver Alert System - sometimes also referred to as LDW (Lane Departure Warning).

The function is intended for use on motorways and similar major roads in order to reduce the risk of the vehicle accidentally leaving its own lane in certain situations.

Lane Keeping Aid's camera sensor has limitations similar to the human eye.

There are some situations where LDW does not give any warning, such as:

  • Direction indicators are switched on
  • The driver has his/her foot on the brake pedal1
  • In the event of rapid depression of the accelerator pedal1
  • In the event of rapid steering wheel movements1
  • If turning is so sharp that the car rolls.
