Abstract: A system controls steering of a motor vehicle in case of an imminent collision with an obstacle. The vehicle includes a system to locate the vehicle relative to its lane and to determine a lateral deviation from the lane center, a determination unit for determining the presence of obstacles, a gyrometer for measuring the rotation speed of the vehicle, and a steering device, the steering angle of which can be controlled based on the measurement of a steering angle sensor or the steering torque of which can be controlled. The control system includes a perception device for determining the maximum lateral distance available for movement of the vehicle relative to obstacles, a decision device for transmitting a correction request based on the trajectory of the vehicle and on the lateral maximum distance, and an intervention device for controlling the steering device to correct the trajectory of the vehicle.

Abstract: A method for automatically controlling a vehicle includes giving a reference local path and a potential speed of the vehicle. The method also includes calculating a stirring angle automatic setpoint that makes it possible to calculate a lateral acceleration proportional to the square of the potential speed of the vehicle, making the vehicle describe an arc of a circle including a point of intersection with the reference local path at a distance from the vehicle. A speed setpoint is generated and set to a value equal to that of the potential speed when the lateral acceleration has a value lower than a maximum permissible lateral acceleration value and the value of the potential speed is decreased when the lateral acceleration has a value higher than or equal to the maximum permissible lateral acceleration value so as to calculate a reduced lateral acceleration by repeating the calculating.

Abstract: A method for controlling the position and speed of a vehicle having steered wheels includes, determining an overall path comprising a plurality of points and defining the course of the vehicle between a starting point and an endpoint; determining the current position of the vehicle; if the current position does not correspond to a point on the overall path, generating a local path connecting the current position of the vehicle to a point on the overall path; and generating control signals in order to steer the steered wheels and control the speed of the vehicle so that the vehicle moves along the local path. The control signals are generated by convex optimization of linear matrix inequalities.

Abstract: The present invention relates to a method for assistance in the parking of a vehicle from a roadway into a free parking space, by one or more maneuvers of the slot parking type, comprising the following steps: determination of the length of the free parking space, determination of an optimum path to be followed by the movement of the vehicle by successive arcs of a circle, characterized in that it comprises a step for determining the number of maneuvers Nm needed in order to bring the vehicle into the parking space and in that these maneuvers are implemented when this number of maneuvers Nm is less than a threshold S2.
