The invention relates to a method for rolling an electrically driven vehicle (10) into a parking lock device (44) from a position in which a pawl (48) is prevented from locking a parking lock gear (46). When the parking lock device (44) is activated, a biasing spring (54) is biased by an actuator (52). A position, identified by position sensing (36), of a parking lock gear (46) accommodated in a rotationally fixed manner is then sent to a control unit (40). Subsequently, an angle of rotation of the rotor shaft (34) of an electric motor (14) which is required to reach the nearest tooth space (60) of an outer toothing (56) of the parking lock gear (46) is determined. The electric motor (14) is then activated in order for the determined angle of rotation to be swept and a controlled approach to be made to the position of the determined closest tooth space (60). The invention further relates to the use of the method for rolling an electrically driven vehicle (10) into a parking lock device (44) from a position in which a pawl (48) is prevented from locking a parking lock gear (46).
