MAN Truck & Bus
An LGS (lane guard system) assists drivers in keeping to their own lane on well-developed roads and monotonous sections. Above a speed of 60 kilometres per hour, the system monitors the vehicle's position with respect to the lane and emits an acoustic signal to warn the driver if the lane marking is accidentally crossed.
The lane marking lines are captured via a Multi-function Camera in the cab. The vehicle's position is evaluated in relation to the lane boundary. If the vehicle leaves the lane without the driver activating the indicators, a "rumble strip" audible warning signal is emitted from the left or right door speakers. Commercial vehicles generally drive with a slight offset to the periphery of the lane. LGS takes this into account by means of an asymmetric warning – the warning threshold is shifted to the periphery of the lane. 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 via the Highline display. The current version of the LGS lane guard system from MAN functions more reliably, conveniently and with substantially reduced error warnings compared to the predecessor system.
