System and method for active lane-changing assistance for a motor vehicle

A method for providing lane-changing assistance to a motor vehicle and configured to assist the vehicle to actively maneuver a change of lane from an initial position on a first lane to a final position on a second lane, which method comprises the steps of:

• determining the initial position of the vehicle and transmitting the initial position to a controller of a lane-changing assistance system of the vehicle;
• determining at least one relative position of at least one other vehicle detected in a vicinity of the vehicle and transmitting the relative position to the controller;
• determining the final position in the dependence on a set of final data containing at least the initial position and at least the relative position;
• creating a virtual clone of the vehicle;
• attributing to the virtual clone localization datum containing at least the final position, the localization datum being configured to simulate by the means of the virtual clone a presence of a dummy real vehicle in the final position;
• emitting, via a communication device of the lane-changing assistance system of the vehicle, the localization datum configured to be received by a further communication device of a further lane-changing assistance system provided on the other vehicle;
• and
• managing, via each said controller provided in the lane-changing assistance system of which the communication device has emitted or received the localization datum, a displacement of the vehicle provided with the controller in dependence on the localization datum;
• and
• wherein a reception of a first and a second localization datum by a same communication device of a lane-changing assistance system of a vehicle is capable of triggering a safety procedure for the vehicle.

A lane-changing assistance system to be provided on a motor vehicle and to facilitate a lane-changing maneuver from an initial position on a first lane to a final position on a second lane, said lane-changing assistance system comprising:

• a controller;
• a localization device for determining the initial position of the vehicle and transmitting the initial position to said controller;
• an obstacle detection system for determining at least one relative position of at least one other vehicle relative to the vehicle and transmitting the relative position of the other vehicle to said controller;
• said controller determining the final position in dependence on a set of final data containing at least the initial position;
• a device for generating a virtual clone capable of creating a virtual clone of the vehicle and simulating by means of the virtual clone a presence of a dummy real vehicle in the final position by generating localization datum of the virtual clone of the vehicle configured to permit a localization of the virtual clone in the final position;
• and
• a communication device capable of exchanging at least one localization datum with at least one further communication device provided in a further lane-changing assistance system of another vehicle and with said controller.
