Control of a Motor Vehicle

A method comprises the steps of detecting a first trajectory of a first motor vehicle while traveling a predetermined route; determining a course of the route based on predetermined map data; determining a quality to which the trajectory and the course correspond; and transmitting the quality to a second motor vehicle. On board a second motor vehicle, a course of a route may be determined on the basis of predetermined map data; a quality associated with the course may be detected; an environment of the second motor vehicle may be scanned; a second trajectory may be determined by merging the course with the scan; and the second motor vehicle may be controlled to follow the second trajectory.
