Abstract

A method and an apparatus for transitioning a motor vehicle from a manual operating mode to an automated or assisting operating mode for driving along a saved trajectory including a memory, in which the trajectory and a tolerance region of the trajectory are saved; a mechanism for ascertaining the location of the motor vehicle relative to the saved trajectory; and a control unit, wherein the control unit is configured so that, if a predetermined criterion is met, a transition trajectory from a current instantaneous position to the saved trajectory is calculated and a steering torque is generated that steers the motor vehicle in the direction of the calculated transition trajectory, wherein the at least one criterion is a distance threshold value with respect to the saved trajectory, wherein the distance threshold value is selected so it is outside the tolerance region.
