The invention relates to a method for determining the absolute angular position of the steering wheel of a motor vehicle. According to said method, first angle measured values, which have been physically detected by a sensor unit that is allocated to a control unit, are continually read by said sensor unit at a constant first interval, are processed and are output in the form of encoded output values via an output interface. The aim of the invention is to improve a method of this type to such an extent that a reliable angular measurement, verifiable by means of plausibility considerations, can be achieved even at high rotational speeds of the steering wheel, at which the difference between two consecutively measured angular values becomes increasingly greater as a result of the constant measuring rate. To achieve this, at least one additional, second angular measured value is read by the control unit for each output value, whereby a second interval lies between the read operations of a respective first angular measured value and a second angular measured value allocated to said first value, said interval being shorter than the first interval.
