Abstract: A method controls a motor vehicle equipped with autonomous driving structure, sensors, fusion circuitry, and a road navigation assistance device. The method includes: determining a first value when the estimated trajectory of the vehicle intersects or approaches the central line of a traffic lane, determining a second value when the closest target object on the vehicle's driving line is also detected by a telemetry sensor, determining a third value when a collision will occur by comparing the distance between the closest target object and the vehicle to a predetermined threshold, determining a fourth value when the space between the vehicle and the closest target object is empty based on data from the telemetry sensor, and determining a fifth value when there is congestion on the trajectory of the vehicle, and then determining whether the autonomous driving structure can be activated based on only the first to fifth values.

Abstract: A method for estimating the speed of a motor vehicle includes defining a first speed threshold that corresponds to a minimum speed value supplied by a vehicle wheel angular speed sensor, defining a second speed threshold that is greater than the first, estimating low speed values when the vehicle is running below the first speed threshold by using an estimation method of adaptive filtered type, measuring high speed values when the vehicle is running above the second speed threshold by using vehicle speed values supplied by the wheel angular speed sensor, and in the intermediate zone between the first and second speed thresholds, mixing high speed with low speed.

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 determining a movement vector of a motor vehicle includes: determining, via a radar system of the vehicle, at two successive instants, positions, relative to the vehicle, of elements of an environment of the vehicle that are static relative to the environment, associating the positions determined at these two successive instants with each other in such a way as to form different pairs of positions each grouping together the preceding position and the subsequent position of a given element of the environment, and determining the movement vector of the vehicle by linear regression, based on the pairs of positions thus formed.

Abstract: A method and device detect the imbalance of a vehicle wheel. The method includes measuring a rotation speed of the wheel while the vehicle is moving, and calculating a filtered value by applying at least one step of band-pass filtering to the measured rotation speed value of the wheel. A position of a pass-band of the band-pass filtering step is offset while moving as a function of the rotation speed of the wheel.

Abstract: A method for a motor vehicle to select a preferred traffic lane to access a toll area having a plurality of traffic lanes includes the following: a) detecting traffic lanes of the toll area, b) determining, for at least some of the traffic lanes, a first item of data relating to the distance between the motor vehicle and the corresponding traffic lane, and a second item of data relating to the number of other vehicles situated on the corresponding traffic lane, c) minimizing a cost function that depends on each first item of data and on each second item of data, so as to identify the preferred traffic lane, and d) determining the possibility or the risk for the motor vehicle of changing traffic lane in order to move towards the preferred traffic lane.
