Abstract: A method for operating a self-driving motor vehicle. A prescribed starting location and a prescribed destination are used to ascertain a driving route. A speed trajectory is determined for the ascertained driving route and the motor vehicle drives along the driving route independently on the basis of the determined speed trajectory. The determination of the speed trajectory includes the following method steps: (i) ascertainment of multiple candidate speed trajectories for the ascertained driving route, (ii) computation of an unpunctuality characteristic value for each of the ascertained candidate speed trajectories, wherein the unpunctuality characteristic value is a measure of a divergence from a prescribed desired time of arrival at the destination, and (iii) selection of that candidate speed trajectory having the unpunctuality characteristic value with the smallest magnitude.
