Abstract: A method for implementing a closed loop of an advanced driving aid device for the lateral control of a motor vehicle includes synthesizing a controller of the closed loop by solving an optimization problem based on a bicycle model of the vehicle. A family of at least two bicycle models of the vehicle is established, these models having, with respect to one another, at least one dispersion chosen from among a dispersion of mass of the vehicle, a dispersion of drift rigidity on a drivetrain of the vehicle, a dispersion of the center of gravity of the vehicle, and a dispersion of the position of the matrix of inertia of the vehicle, the optimization problem being solved on the basis of all models of the family.

Abstract: A system for controlling a power propulsion unit of a hybrid type for a four-wheel-drive automotive vehicle that includes at least one electric motor part and at least one thermal engine part capable of driving the independent front and rear driving axles of the vehicle. The system includes a mechanism determining total torque set point from a request of the driver, a mechanism distributing the total torque set point, and a system optimizing the duty point, to dynamically determine the torques to be applied to each of the two driving axles and to optimize fuel consumption of the power propulsion group according to the drivability requested by the driver and driving conditions.
