摘要： The invention relates to a vehicle or traffic control method and to a vehicle or traffic control system. The vehicle or traffic control method comprises the steps: a) estimating actual and/or future behavior of a first traffic participant and of a second traffic participant, respectively, the second traffic participant being different from the first traffic participant, b) estimating a trajectory to be taken by the first traffic participant and/or a trajectory to be taken by the second traffic participant, c) determining risk of collision of the first traffic participant relative to the second traffic participant by calculating information adapted for risk assessment of collision of the first traffic participant relative to the second traffic participant, and d) controlling the behavior of the first traffic participant based on the information provided after step a), step b) and/or step c). In this way a probability value is determined which indicates the plausibility that a vehicle or traffic participant might enter into collision within a certain time horizon in the future.

摘要： A vehicle driving aid method includes and defining an occupation grid corresponding to discretization into N cells of a field of kinematic parameters of a detected object; acquiring at each time k an observation zk produced by a sensor and determining a sensor probability modeling the behavior thereof; calculating for each cell X, a predicted occupation probability providing the probability that the cell X is, at time k, in occupied state having knowledge of a density of estimated of occupation of the grid a the preceding time; calculating for each cell X, an estimated probability of occupation providing the sensor probability and predicted occupation probability; the latter at time k determined by supposing that a single cell of the grid constitutes, at time k−1, the antecedent of the cell X concerned; evaluating, for each cell X, a collision probability, based on the estimated probability at time k and emitting a signal to avoid the object.
