摘要： A method for determining the position of a movable element to be driven by a direct current motor between first and second positions includes counting ripples contained in a motor current signal as the motor rotates to drive the element. The position of the element is determined based on the counted ripples. The motor actuates, until the current signal is void of ripples, to move the element into the first position when the element is to be moved out of the first position towards the second position. The counted ripples is reset to a reset value after the motor has been actuated to move the element into the first position such that the reset value corresponds to the position of the element being in the first position. The motor actuates to move the element towards the second position after the counted ripples has been reset.

摘要： An electrical circuit arrangement for controlling a unit, such as an adjustment system for windows or a sliding sunroof, that is driven by a motor and is situated in a motor vehicle. The arrangement guarantees that, in the case of a short-circuit of circuit components, especially a control device operation of a motor is still possible, especially in a preferred direction of motor rotation, whereby the direction of rotation results in an opening of the unit and the short-circuit is caused by salt water for instance. Two circuit-breaker elements that operate the motor in either direction can be directly activated by an allocated circuit device which bypasses a failed control device. The remaining circuit-breaker element is blocked at least when the first circuit-breaker element is activated.
