Components of the  MEKRA Turn Assist System (AAS)

The Side Defender is a radar based object detection system with a FMCW-radar sensor. The radar alerts the driver of a large commercial truck or communal vehicle if there is a vulnerable road user in the blind spot of the vehicle, i.e. bicyclist, other vehicles and pedestrians. Thanks to its smart operating modes, the AAS triggers alerts when bicyclists or other vehicles enter the detection zone. False alerts due to stationary objects are kept to a minimum (i.e. guard rails or parked cars).


The in-cab display on the A-pillar provides visual and audible alerts when potentially dangerous conditions arise next to the vehicle. Combined with our camera system is this a perfect solution to eliminate the dangerous blind spot.
