Abstract: A method generates a setpoint for controlling a steering system and a differential braking system of a motor vehicle. The method includes: acquiring a value relating to a total yawing moment to be applied to the motor vehicle such that it follows a required path, and the speed of the motor vehicle, calculating, as a function of the speed, at least one threshold relating to the maximum proportion of the total yawing moment that the steering system or that the differential braking system can provide, determining, as a function of the threshold, a distribution rate relating to the proportion of the total yawing moment that the steering system or that the differential braking system must provide, and generating a setpoint for controlling the steering system and the differential braking system as a function of the distribution rate and of the value relating to the total yawing moment.

Abstract: A device for assisting in the driving of a motor vehicle includes a line detector for detecting the boundary line of a traffic lane, a setup module capable of establishing a virtual lane from the line detected, a monitoring module capable of monitoring the risk of the motor vehicle leaving the virtual lane established. The device also includes a module for acquiring an image representing a relevant object. The setup module includes a first map containing values of a position of a virtual-lane boundary according to a lateral shift of the relevant object in the acquired image.

Abstract: An assistance device for driving in a traffic lane for a motor vehicle includes a module for determining at least one input variable chosen from among variables related to the vehicle and variables related to the traffic lane, a module for producing a correction instruction according to the input variable, and an assistance module capable of implementing a driving assistance action according to the correction instruction. The input variable includes a lateral position of the vehicle in the traffic lane and a lateral deflection speed of the vehicle.

Abstract: A method detects a risk of collision between a motor vehicle and a secondary object located in traffic lanes adjacent to the main traffic lane of the vehicle, in the event of a lane change by the vehicle, which involves detecting objects in a predetermined danger zone, and estimating a time-to-collision between the vehicle and a detected object. Detecting objects in a danger zone involves: calculating the actual distance between the vehicle and each object detected by the radar, the actual distance corresponding to the length of an arc between two points; determining a danger zone as a function of lines of the main traffic lane and a width of the main traffic line; and checking, for each object detected by the radar, whether its coordinates are inside the predetermined danger zone.

Abstract: A method for determining an avoidance path of a motor vehicle includes the steps of:—acquiring data relating to an obstacle located in the surroundings of the motor vehicle by means of a detection system,—determining a final position to be reached according to the position of the obstacle and an initial position of the motor vehicle,—calculating a theoretical impact position located between the initial position and the final position, and—developing the avoidance path such that the motor vehicle passes through the initial position and the final position and avoids the theoretical impact position around the outside.
