1. A stroller frame, comprising:
a sensor unit for capturing sensor data at a sampling frequency; and
a drive unit; and
a computing unit coupled to the sensor unit and coupled to the drive unit,
wherein the computing unit is configured to switch the drive unit between a driving state and a non-driving state as a function of a comparison of the sensor data and a tolerance interval,
wherein the computing unit is configured to switch the drive unit to the non-driving state if fewer than a predetermined number of temporally contiguous measured values of a subset of the sensor data are not within the tolerance interval and configured to switch the drive unit to the driving state if a predetermined number of the temporally contiguous measured values of the subset are within the tolerance interval; or
wherein the computing unit is configured to switch the drive unit to the non-driving state if a statistical measure of a spread of the measured values of the sensor data is within the tolerance interval and configured to switch the drive unit to the driving state if the statistical measure of the spread of the measured values is outside the tolerance interval.
