Method for carrying out a closing operation, closing device, server apparatus and communication terminal for carrying out a method of this type

A method for carrying out a closing operation of a closing part of a closing device of a vehicle driven by an electric motor drive unit, wherein the method comprises the following steps:

• ascertaining friction force data representing a current stiffness of the closing device in a control unit using a model,
• ascertaining target drive power data for the drive unit that take the friction force data into consideration, and
• operating the drive unit based on the ascertained target drive power data to perform the closing operation during at least one subsequent closing operation,
• wherein the model was generated by a machine learning method on an external server device, wherein the machine learning method is trained with frictional force reference data as input data from previous closure operations, wherein the input data is transmitted from the control unit to the external server device to update the model, and where the model is updated based on current input data in response to a trigger event in the external server device and transferred to the control unit in an updated form.
