The invention relates to a method for generating a surroundings map (14) of a surrounding area (7) of a motor vehicle (1) in which an object in the surrounding area (7) is detected by means of a sensor device (9) of the motor vehicle (1), a position value (P) that describes a position of the object is determined on the basis of sensor data of the sensor device (9) by means of a control device (3) of the motor vehicle (1) and the determined position value (P) is transferred into the surroundings map (14), wherein a vector (v′) between the object and a predetermined reference point (11) of the motor vehicle (1) that forms an origin (0′) of a vehicle coordinate system (12) is determined, the determined vector (v′) is transformed from the vehicle coordinate system (12) into a global coordinate system (13) of the surroundings map (14) and the position value (P) in the surroundings map (14) is determined on the basis of the transformed vector (v).
