  • Method of characterizing the condition of a road
    Patent number: 11530932
    Abstract: The invention is a method of characterizing a road for at least one route travelled by at least one road user, with sensors: a three-axis accelerometer (ACC) and a geolocation sensor (GPS). The method comprises a measurement step (MES), a measurement processing step for disregarding (AFF) the effects related to the road user's speed in order to determine vibrations due to the road roughness, and an analysis of the vibrations to characterize (CAR) the condition of the road.

  • METHOD FOR DETERMINING A NUMBER OF VEHICLE CROSSINGS ON AT LEAST ONE ROAD PORTION OF A ROAD NETWORK
    Publication number: 20220148418
    Abstract: The present invention relates to a method for determining a number of vehicle crossings (Ntot) on at least one road portion of a road network, wherein measurements using fixed sensors (1) and geolocation measurements (GEO) are performed. For this method, a spatialized scalar field (SCA) is determined. Finally, the number of vehicle crossings (Ntot) is determined by way of the determined spatialized scalar field (SCA) (which depends in particular on the measurements using fixed sensors and the geolocation measurements (GEO).

  • Method of controlling a positive-ignition internal combustion engine by means of a knock estimator
    Patent number: 10830659
    Abstract: The present invention relates to a method of controlling a positive-ignition internal combustion engine, in which the ignition advance is controlled (CON) by means of an estimation (EST) of the distribution of the knock measurements (MEAS). This estimation (EST) makes it possible to determine, for these measurements (MEAS), a confidence interval (qmin, qmax) of a predetermined quantile of the distribution of the knock measurements (MEAS).
