Method for controlling modules for projecting pixelated light beams for a vehicle

A method for controlling projection modules for projecting pixelated light beams from a host vehicle, the host vehicle comprising

• a set of sensors, and
• at least one device for controlling light beam projection modules,
• wherein the method comprises:
• collecting, via a data acquisition device, a set of data used to model a profile of a road stretching in front of the host vehicle;
• determining, via a control device and according to the set of data collected, a polynomial function modeling the profile of an edge and of a center of the road, such that
• the modeling of the profile of the road results from a first degree polynomial function of the form y=f(x)=Bi.x+Ai when the profile of the road is rectilinear,
• the modeling of the profile of the road results from a second degree polynomial function of the form y=f(x)=Ci.x2+Bi.x+Ai when the profile of the road is parabolic, or
• the modeling of the profile of the road results from a third degree polynomial function of the form y=f(x)=Di.x3+Ci.x2+Bi.x+A when the profile of the road comprises an inflection point;
• determining, via the control device, a starting point (Pd) and an end point (Pa) of a projection zone for projection of patterns;
• determining, via the control device, a distance (Dc) between an axis (Ac) of the data acquisition device and patterns of a right projection zone of the projection zone and patterns of a left projection zone of the projection zone;
• and
• determining, via the control device, a width (Lm) of the patterns.
