摘要

A method for increasing the availability of path - / position measuring systems on the basis of potentiometers with slider tap in a closed control loop, the controller is formed by a microcontroller, which the position of the slider via an analog / digital - converter is supplied, characterized in that within the active processing step, generally available by the evaluation of a circle size of the precise position of a defective slider position of the potentiometer is determined and the input to the control circuit of overcharging defined, so that the defective slider position in the case of the path - / position measurement is avoided and an intact slider position is reached.
