Claim:
1. A method for evaluating output signals of a rotational rate sensor unit, comprising: providing an n-tuple-of angular speed values measured by at least one rotational rate sensor of the rotational rate sensor unit, in a first method step; determining an intermediate value as a function of the n-tuple of angular speed values, in a second method step; calculating a new change of orientation value as a function of the intermediate value and as a function of an earlier change of orientation value stored in a register of the rotational rate sensor unit, in a third method step; and storing the new change of orientation value in the register, in a fourth method step; wherein the first, second, third, and fourth method steps are repeated until, at least one of: i) in a fifth method step, the new change of orientation value is read out by an external data processing unit connected to the rotational rate sensor unit, and ii) in a sixth method step, an exceeding of a threshold value is detected, and wherein a current change of orientation value is successively summed by multiple repetition of a loop including the first, second, third, and fourth method steps, so that all of the items of change of position information are represented in the new change of orientation value.
