The present invention describes a method for actuating the cruise control function in a vehicle equipped with hybrid driving, comprising at least a primary driving and an electric driving. The method comprises the steps of: —cyclic check of the possibility of activation of the cruise control function; if positive—activation of the electric driving of the type “electric cruise-control” (ElCC), and deactivation of the primary driving, if a cyclic check of the conditions of activation of the electric driving is positive; otherwise—activation of the primary driving of the type “engine cruise-cruise control” (EnCC), and deactivation of the electric driving.
