Abstract: A method secures a host vehicle circulating on a traffic lane of a road infrastructure including at least one lane adjacent to the traffic lane. The securing method includes, for each adjacent lane: detecting a plurality of vehicles present on the adjacent lane, including an estimate of at least one information item relating to each detected vehicle, including the speed; determining, with the detected vehicles forming a flow of vehicles, a value representing the speed of the flow on the adjacent lane, for example, the average speed; comparing the speed of the host vehicle with the value representing the speed of the flow of vehicles on the adjacent lane; and, if the speed of the host vehicle is greater than a predetermined threshold at the value representing the speed of the flow of vehicles on the adjacent lane, detecting a hazardous situation for the host vehicle.

Abstract: A device for controlling, in real time, the trajectory of an autonomous vehicle includes a control module which produces, in real time, from a state vector at each point in time, a first steering command in order to stabilize the trajectory of the vehicle relative to a vehicle path. The device includes an anticipation module which generates a variable representative of a meta-vector of deviations for each predicted position of the vehicle at points in time resulting in a given quantity at the current point in time and of the state vector at the current point in time. The control module produces the first steering command by quadratic optimization of a relationship between the generated representative variable and a meta-vector of successive steering commands for each predicted position of the vehicle at points in time resulting in a given quantity at the current point in time.
