Abstract (en)

[origin: WO2007028932A1] The invention concerns a vehicle steering aid method comprising an object sensing detector, including the following steps which consists in: defining an occupation grid corresponding to discretization into N cells of a field of kinematic parameters of the detected object; and, at each time k, acquiring an observation z<SUP>k</SUP> produced by the sensor and determining a sensor probability modelling the behaviour 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 probability of occupation of the grid at the preceding time; calculating for each cell X, an estimated probability of occupation providing the sensor probability and the predicted occupation probability; the predicted occupation probability at time k being 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.
