    摘要： The invention concerns a method of driving assistance for assisting a human driver in safely driving a vehicle called host vehicle, implemented by a processor on board of said host vehicle. The host vehicle comprises means for obtaining first information relative to the host vehicle and means for obtaining second information relative to at least one other vehicle in a neighborhood of the host vehicle, said first and second information being obtained at regular time instants, comprising triggering an intervention of a collision avoidance system. The method comprises a step (51) of intervention decision adapted to decide whether to trigger the intervention of the collision avoidance system at a current time instant (Tc) or to postpone said intervention decision at a later time instant (Tl) depending upon additional first and second information to be acquired between the current time instant (Tc) and the later time instant (Tl), said additional first and second information having an associated probability. The invention also concerns an associated system of driving assistance.

    摘要： A computerized device for driving assistance comprises a memory (4) designed to receive data point cloud data (8) in which a point cloud associates, for a given instant, points each having coordinates in a plane associated with the point cloud and a value denoting a height. The device furthermore comprises a calculator (6) designed to access the memory (4) and, for a given point cloud, to calculate data on the probability of belonging to a reference surface, associated with each point of the data point cloud, on the one hand, and node data associating a value denoting a height (hi) and two values indicating a slope in a plane associated with the plane of the given point cloud, on the other hand, by determining a Gaussian random conditional field by way of the data point cloud data (8) corresponding to the given point cloud, which Gaussian random conditional field is represented by a mesh of nodes in said associated plane, which nodes are defined by the node data, and to return the data on the probability of belonging to a reference surface and/or at least some of the node data and values denoting a height.

    摘要： The invention concerns a method for assessment of abnormal driving behaviour to improve driving safety of a vehicle travelling on a road, using position information and motion information about said vehicle and/or at least one neighbouring vehicle travelling in the proximity of said vehicle on said road. The method comprises a step of obtaining and memorizing (40, 42) a plurality of position information items and motion information items, each information item corresponding to a measuring time instant of an observation time interval and a step of obtaining (44) at least one estimate of the reference value for said vehicle and/or its at least one neighbouring vehicles travelling on said road during the observation time interval. Next, the sets of deviation values are computed (46), each deviation value being computed using a memorized information item corresponding to a measuring time instant and the at least one estimate of the reference value and the quantities of deviation are obtained from the corresponding sets of deviation values. If a quantity of deviation among said quantities of deviation is greater than a predetermined threshold for the corresponding driving behaviour, the method implements (52) a measure for safety improvement.
