Abstract: A device synchronizes primary speed of a primary shaft receiving an electrical torque from an electric machine with a secondary speed lower than the primary speed of a secondary transmission shaft. The primary shaft and secondary shaft are decoupled. The primary shaft has a kinetic energy associated with the primary speed. The device provides electrical braking torque to the primary shaft until the primary speed is substantially equal to the secondary speed. The device also at least partially recovers, in the form of electrical energy, the kinetic energy lost by the primary shaft and transmits the electrical energy to an energy storage device.

The device includes a phase-locked loop to determine an instantaneous frequency of the network as a function of a measurement of a voltage of an electrical supply network, a regulating mapping to determine a neutral current setting as a function of a setting of battery current, a device to calculate an amplitude of a frequency variation of the network as a function of the instantaneous frequency, a correction mapping that receives as input a value of the amplitude of the frequency variation and emits as output a correction value of the neutral current setting, and a summer to determine a corrected neutral current setting by adding the correction value of the neutral current setting to the neutral current setting.

Abstract: A method for managing longitudinal speed of an autonomous vehicle travelling on a traffic lane including stop signage located in front of the autonomous vehicle. The autonomous vehicle is equipped with a first detector to detect a first range and a second detector to detect a second range. The first range is greater than the second range. The method includes detecting the stop signage by the first detector and implementing a first deceleration logic and detecting the stop signage by the second detector and implementing a second deceleration logic. The first and second deceleration logic implement jerks, the absolute value of which is less than a first threshold. The second deceleration logic controls the stopping of the autonomous vehicle with an accuracy of around one centimeter relative to the stop signage.

Abstract: An anticipating module for a device for controlling, in real time, the path of a motor vehicle includes a sub-module for computing a turning command for compensating for the curvature of a bend in the lane of the vehicle and a variable-gain device that is connected to an output of the computing sub-module. The gain of the variable-gain device is connected to a controller to adjust the gain so as to decrease the lateral offset between the centre of gravity of the vehicle and the centre of the lane of the vehicle depending on the result of the comparison of components of a vector of current measurements of state variables of the device to one another and to a detection threshold, the output of the variable-gain device being the steering command for compensating for the curvature of the bend.

Abstract: A method for automated management of the longitudinal speed of a first vehicle travelling on a first lane includes: detecting an intention of a second vehicle travelling on a second lane adjacent to the first lane to perform an insertion maneuver on the first lane; estimating a corrected longitudinal distance, the corrected longitudinal distance corresponding to the longitudinal distance that will separate the first vehicle from the second vehicle at the end of the insertion maneuver, the corrected longitudinal distance being calculated as a function of a measured longitudinal distance between the first vehicle and the second vehicle, and as a function of a relative longitudinal speed measured between the second vehicle and the first vehicle; and calculating a longitudinal speed setpoint of the first vehicle as a function of the corrected longitudinal distance.

Abstract: A method for setting an anticipator module with which a control device controls the trajectory of a motor vehicle is equipped includes detecting whether the anticipator module is unsuitable during a turn by taking account of a lateral deviation with respect to an ideal trajectory and/or a contribution of a feedback module of the control device, determining primary parameters, calculating a secondary parameter by an optimization-based calculation method taking account of the determined primary parameters, and updating a bicycle model of the vehicle by taking account of the calculated secondary parameter.

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.
