1. A method (100) for shifting an electrically shiftable transmission (230) for a vehicle (200a), wherein the method (100) comprises the steps of:
ascertaining (110) a constraint (310) relating to a shifting element (235) of the transmission (230);
determining (120) a motion profile (300) for the shifting element (235) on the basis of the constraint, wherein the motion profile (300) defines a position (P) of the shifting element (235) as a function of time (t); and
outputting (130) a regulation signal (255) for regulating the position of the shifting element (235) on the basis of the motion profile (300);
wherein the constraint (310) comprises an impact velocity (315) at a constraint position (P2, P3).
