A method () for shifting an electrically shiftable transmission () for a vehicle (), such as a commercial vehicle, is provided. The method () includes ascertaining () a constraint () relating to a shifting element () of the transmission () and determining () a motion profile () for the shifting element (). The motion profile () defines a position (P) of the shifting element () as a function of time (t). The method further includes outputting () a regulation signal () for regulating the position of the shifting element () on the basis of the motion profile ().

Method for shifting an electrically shiftable transmission for a vehicle, in particular a commercial vehicle

A method () for shifting an electrically shiftable transmission () for a vehicle (), in particular a commercial vehicle () includes detecting () a state () of a shifting element () relating to a blocking position () of a shifting element () relative to a further shifting element (). A control signal () for controlling a movement of the shifting element () is determined, taking into account the detection of the blocking position (). The control signal () defines a target variable (Z) of the movement of the shifting element () and an oscillation (O) about the target variable (Z). The control signal () is output and moves the shifting element () out of the blocking position and into a final position of engagement with the further shifting element ().
