Method and system for motor-driven assistance of the movement of a vehicle door, wherein the vehicle door is driven by means of an electric motor, which is controlled by a control unit, depending on a force exerted on the vehicle door by an operator, in a manner assisting this force or exceeding the force, comprising the steps:



the voltage induced in the electric motor due to the force exerted on the vehicle door by the operator is detected and transmitted to the control unit,
this electrical voltage or a signal derived from it is compared with prescribed threshold values in the control unit during a defined, adjustable time interval, and
the motor is driven by the control unit, depending on whether the threshold values are exceeded or undershot, in a manner merely assisting the force exerted on the vehicle door by the operator or exceeding the force.
