Abstract: A door component for pivoting a movable door of a motor vehicle has a drive with an electric drive motor in order to influence a pivoting of the door between a closed setting and an open setting. A position measure for an angular setting of the door leaf and a speed parameter for an angular speed of the door leaf are detected by a position sensor.

Then the current intensity flowing through the drive motor is ascertained. The setpoint voltage is increased if the current intensity is lower than the electrical setpoint current intensity, and the setpoint voltage is decreased if the current intensity is higher than the electrical setpoint current intensity.
