    Abstract: A method for displaying a graphical representation for an arrangement including a vehicle body, a device for displaying the graphical representation including a storage unit for storing digital data, at least one display being integrated into a front segment of the vehicle, and/or a rear segment of the vehicle, and a control unit for controlling the display, the display including a face intended for readout of the graphical representation and oriented toward the exterior. The method includes selecting, via the control unit, an animation script and image stored beforehand in the storage means, the image especially being a three-dimensional representation of an object, especially a logo.

    Abstract: A device estimates the electromagnetic torque of a three-phase synchronous electric machine including permanent magnets. The device includes: a first flux estimator including two integrators of electromotive force for estimating the respective components of the flux in a fixed two-phase coordinate system tied to the stator, an estimator for estimating the torque from the respective estimated-flux components, a second flux estimator that uses currents expressed in a rotating two-phase coordinate system tied to the rotor, with an observer for determining variables that characterize magnetic uncertainties of the machine with a view to correcting the flux estimation of the second estimator, and a detector for generating a signal for resetting initial flux conditions of the two integrators based on the flux estimation delivered by the second estimator, when the discrepancy between the estimated torque and a setpoint torque is higher than a predefined threshold.

    Abstract: A method corrects the time defined by an internal clock of an entity capable of receiving signals from a satellite positioning system and of communicating with at least one other entity. When the signals do not allow the satellite positioning of the entity, the method includes: receiving, by the entity, a message originating from the other entity, the message including a first piece of time data associated with the instant the message was transmitted; determining, by the entity, a second piece of time data associated with the instant the message was received by the entity; calculating a time difference between the second piece of time data and the first piece of time data; and then, when the time difference is negative, determining a time correction to be made to the internal clock of the entity.

    Abstract: A method for estimating a precise position of a vehicle on a map includes acquiring at least one geolocated position of the vehicle by way of a geolocation system, pre-positioning the vehicle on the map, and particle filtering in which possible positions of the vehicle, called particles are processed. The particle filtering includes distributing particles on the map, and then updating the particles on the map, calculating the likelihood of each particle, selecting a limited set of particles, and, if an indicator relating to the likelihood of the selected particles and to the number of selected particles drops below a threshold, resampling particles on the map.

    Abstract: A device and method for detecting when at least one heat source exceeds a temperature threshold. The device includes a component having an electrical resistance that varies according to the operating temperature of the component, and an electrical power source suitable for supplying an electrical current to the component. The component is configured to be thermally coupled to the heat source, such that the operating temperature varies according to the temperature of the heat source and the heat released in the component by the Joule effect, the variable electrical resistance having a high value if the operating temperature is greater than a triggering threshold, the electrical power source being configured to generate the electrical current such that the operating temperature is greater than or equal to the triggering threshold once the temperature of the heat source is greater than or equal to the temperature threshold.

    Abstract: A method is for autonomously driving an actuator of an automotive device. The actuator is intended to have an influence on the trajectory of the device. The method includes acquiring parameters relating to the trajectory of the device and a computer calculating a setpoint for driving the actuator as a function of the parameters via a controller associated with at least one saturation function for an output of the controller. The controller satisfies a model of the at least one saturation function per nonlinear sector.
