1. A method for controlling an industrial vehicle during a road surface treatment operation of a road route carried out by the industrial vehicle using first treatment parameters, comprising the steps of:
detecting at least one of: i) a physical feature in said road route, ii) an actual variation of the travel direction of the industrial vehicle in said road route, and iii) a planned variation of the travel direction of the industrial vehicle in said road route,
wherein said physical feature determines a local narrowing or widening of said road route, and said actual variation and planned variation determine a corresponding variation of a first distance of the industrial vehicle from a first edge of the road route and of a second distance of the industrial vehicle from a second edge of the road route;
calculating, as a function of said first and second distances, and/or as a function of said local narrowing or widening, second treatment parameters of the road surface; and
in case of actual variation of said travel direction, controlling the immediate implementation of the second treatment parameters by the industrial vehicle;
otherwise carrying out the steps of:
calculating an estimated time for reaching said variation of the travel direction or physical feature,
calculating a time interval value required for a complete implementation of the second treatment parameters, and
starting the implementation, by the industrial vehicle, of the second treatment parameters at a time that is equal to the estimated time excluding the time interval of complete implementation.
