The invention relates to a method for meshing a starter pinion (19) of a starting device (16) into a ring gear (13) of an internal combustion engine (10). The internal combustion engine (10) has a driveshaft (22), and the starting device (16) has a starter motor (25), said driveshaft (22) having a variable rotational speed (n). The internal combustion engine (10) is switched off in a method step (S1), and the starter pinion (19), which is not being rotationally driven by the starter motor (25), is then advanced in the direction of the ring gear (13) by a toe-in actuator (28) by means of a toe-in force (FV) in a method step (S2) until the starter pinion contacts the ring gear. A meshing force (FE) is then exerted onto the starter pinion (19) in a controlled manner in an additional method step (S3) in order to mesh the starter pinion (19) into a tooth gap (34) of the ring gear (13).
A method for meshing a starter pinion (19) of a starting device (16) into a ring gear (13) of an internal combustion engine (10), wherein the internal combustion engine (10) has a driveshaft (22) and the starting device (16) has a starter motor (25), wherein the driveshaft (22) has a variable rotation speed (n), and in a method step (S1) the internal combustion engine (10) is switched off and then in a method step (S2) the starter pinion (19), which is not driven in rotation by the starter motor (25), is advanced by means of a pre-meshing force (FV) using a pre-meshing actuator (28), in a direction of the ring gear (13) until said starter pinion (19) touches said ring gear (13) and then in a further method step (S3) a meshing force (FE) is selectively applied to the starter pinion (19) in order to mesh the starter pinion (19) in a tooth gap (34) of the ring gear (13).
