Abstract
A method for assisting the driver of a vehicle that comprises an analysis means which analyzes the environment in an area located in front of the vehicle in order to detect boundaries and traffic signs and to provide environmental data representative of said boundaries and traffic signs, and a control means which controls the automated driving of said vehicle. Said method comprises a step in which the environmental data are analyzed to determine a variation in speed limit correlated temporally with a variation in the number of traffic lanes, and when such a determination is made, it is considered that the vehicle is located close to a restricted area and an alert is generated requesting that the driver take back control of the driving while crossing said restricted area or that a specific automated driving strategy be implemented by the control means for said crossing.
