  • Patent number: 11891048
    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.

  • Publication number: 20240034311
    Abstract: A method controls a motor vehicle equipped with at least two perception sensors to avoid a target. The control method includes: determining data of the sensors, fusing the data of the sensors so as to determine the steering wheel angle, the vehicle speed and the vehicle heading, planning an avoidance path to avoid the target, taking the form of a Euler spiral, refining the avoidance path depending on the steering wheel angle, on the vehicle speed and on the vehicle heading and based on the solution of an optimisation problem, controlling the vehicle so as to follow the refined path, the refining the path including honing the avoidance path depending on the path length, on the direction of steering wheel rotation and on the final heading and refining the honed trajectory depending on the initial heading and on the direction of steering wheel rotation.

  • Publication number: 20220379883
    Abstract: A method automatically controls an actuator of a control system of an automotive device. The method includes determining a reference trajectory, determining a position of the device with respect to the reference trajectory, acquiring a parameter relating to a force exerted by a driver on a manual control device of the control system, and calculating a controlling setpoint of the actuator. The controlling setpoint is calculated as a function of the parameter and of the position of the device with respect to the reference trajectory.
