Method for switching the headlights of a vehicle from full beam to the dipped position and vice versa, said vehicle being provided with at least one image acquisition sensor facing in the direction in which the vehicle is travelling and suitable for detecting the presence of at least one second vehicle, comprising the steps of: a. acquiring by means of said at least one acquisition sensor one or more successive images having a plurality of chromatic shade levels; b. splitting each of said at least one or more images acquired into an array of cells, each cell of said array of cells being associated with an intensity value which corresponds to the chromatic shade level identified for said one or more images during step a) of the method; c. processing each cell of said array of cells to identify the presence of said at least one second vehicle; d. switching the position of the headlights from full beam to the dipped position according to the presence of said at least one second vehicle detected during step c) of the method; characterised in that step c) of the method comprises the step of: e. calculating for each array of cells one or more areas of greater intensity according to the maximum intensity value identified on at least one cell of said array of cells; f. calculating the relative distance between said two vehicles by comparing the areas of greater intensity identified during step e) of the method with one or more previously defined reference values. |
