    摘要： A movably arranged vehicle component is operatively coupled to and may be driven by an electric motor. The electric motor is supplied with a motor current to drive the movement of the vehicle component. A method for detecting a movement obstruction comprises the steps of supplying the electric motor with a supply voltage, thereby supplying the motor current; determining a frequency content of the motor current; and analysing the frequency content to determine whether the movement obstruction is present or not.
    A motor control system is configured to perform the above-mentioned method.

    摘要： An arrangement for a movable roof element (101) for a motor vehicle (100) has: – a carriage (103) which is designed to be guided in a rail (104) and to be moved relative to the rail (104), and which has a first component (105) and a second component (106), and – a drive cable (107), wherein the second component (106) at least partially surrounds the first component (105) and the drive cable (107) in order to form a coupling (108) between the drive cable (107) and the carriage (103), wherein the coupling (108) has: – a roughening (109) of the first component (105) in order to form a frictional and/or integrally bonded connection between the first component (105) and the second component (106).
