The invention relates to a method for autonomously parking a motor vehicle (1), in which the motor vehicle (1) is positioned in a start position (5), wherein the start position (5) is associated with a parking area (7) with a plurality of parking spaces (6), by means of a parking control device (4), one of the parking spaces (6) is selected for parking for the motor vehicle (1) and a trajectory (12) for autonomously moving the motor vehicle (1) from the start position (5) to the selected parking space (6) is determined, wherein interior data describing an interior (16) of the motor vehicle (1) is received by means of the parking control device (4), and it is examined based on the received interior data if a living entity is in the interior (16) of the motor vehicle (1), and the moving of the motor vehicle (1) along the determined trajectory (12) remains undone if the living entity is in the interior (16).
