Abstract:
A vehicle for spreading at least one de-icing product on a road surface comprising:distribution means borne by the vehicle and adapted to spread said product on the road surface;electronic control means operatively connected to said distribution means for controlling the spreading of said product by said distribution means in response to operating parameters including a quantity operating parameter, a spreading width parameter, a spreading symmetry parameter and a humidification parameter of the de-icing product, whereinthe electronic control means includes positioning means for generating a position signal correlated with the position of said vehicle, and the electronic control means cooperating with said positioning means in order to associate values of said operating parameters with each position of the vehicle detected along a route; andself-learning means for generating a plurality of values for each operating parameter, each of said values being associated with a position detected along the route which the vehicle is traveling, wherein the self-learning means includes:means for manually inputting said values of operating parameters;detection means for acquiring a position signal generated by the position generating means;means for correlating the inputted values of said operating parameters with said position signal;memory storage means for storing said operating parameters and a position signal associated therewith in a memory; andmeans for cyclical selection of said inputting means, detection means and correlation means adapted to process a plurality of values of said operating parameters in connection with respective positions of a road route traveled by the vehicle.
