1. A method for ascertaining a vehicle trajectory, comprising:
detecting, by a plurality of motor vehicles, traveled individual trajectories and secondary information linked to the individual trajectories, wherein the individual trajectories comprise position information and lane information linked thereto, and the secondary information includes data related to vehicle dynamics, road conditions, and/or traffic patterns as sensed by onboard sensors and processed to form the individual trajectories and associated secondary information;
transmitting, by the plurality of motor vehicles, the individual trajectories and the secondary information linked thereto to a network server;
aggregating and processing, by the network server, the received individual trajectories, including the position information and the secondary information linked thereto to ascertain a swarm trajectory, wherein the network server utilizes the secondary information to dynamically weight the individual trajectories based on varying road conditions, vehicle dynamics, and traffic patterns;
configuring the swarm trajectory for transmission to at least one motor vehicle based on the aggregated position information and the secondary information; and
transmitting, via wireless communication, the configured swarm trajectory to the at least one motor vehicle; and
automatically adjusting, by the at least one motor vehicle using a driving system, its current trajectory based on the received swarm trajectory, resulting in modified vehicle steering, acceleration, or braking.
