LGS – lane guard system
Lane Guard System (LGS)
Greater safety in traffic thanks to lane monitoring
On long and monotonous routes or during nighttime driving the driver's attention sometimes wanes – or he may even fall asleep for a second. The lane guard system (LGS) monitors whether the vehicle stays correctly in lane, thus ensuring greater safety and driving comfort. If the vehicle leaves its lane without the driver having actuated the direction indicators an acoustic signal sounds to warn the driver.
Function and operation
A video camera behind the windscreen records the lane markings and vehicle's position in respect of the lane markings. If the vehicle crosses the lane markings the driver is warned by the sound of "rattling nails" from a loudspeaker near the right-hand or left-hand door, depending on which lane marking has been crossed. The system activates itself automatically at speeds over 60 km/h and can be deactivated via a rocker switch. At speeds below 75 km/h the warning is sounded when the vehicle reaches the inner lane marking and above 75 km/h at the outer lane marking. If no warnings can be given, e.g. because there are no lane markings, the driver is informed accordingly by means of a check lamp or by the Highline display.
