1. A method for automatically controlling at least one following vehicle, the method comprising: producing a scout trajectory for a scout vehicle; guiding the scout vehicle along an actual trajectory, the actual trajectory of the scout vehicle and scout environmental data is captured by scout sensors; producing a desired trajectory for the following vehicle and following vehicle environmental data are captured by following vehicle sensors; determining a scout trajectory similarity based on the scout trajectory produced and the captured actual trajectory, reference trajectory data are produced and reference environmental data are produced based on the scout environmental data; transmitting the reference trajectory data and the reference environmental data to the following vehicle; determining a trajectory similarity by a trajectory comparison based on the desired trajectory produced and the transmitted reference trajectory data; determining an environmental data similarity by an environmental data comparison based on the captured following vehicle environmental data and the transmitted reference environmental data, in which case: in response to the trajectory similarity and/or the environment similarity exceeding a particular threshold value, automatic control of the following vehicle is activated, and in response to the trajectory similarity and/or the environment similarity not exceeding a particular threshold value, a safe driving mode of the following vehicle is activated.
