Abstract: The invention relates to a method for processing, by a computer system (100) installed on board a motor vehicle, a signal transmitted by a remote communicating entity and received by means of a radiofrequency signal communication apparatus arranged inside the vehicle, and to a system implementing such a method and to a motor vehicle comprising such a system. The aim of the invention is to determine the plausibility of a radiofrequency signal transmitted by a remote communicating entity, in particular a signal that contains data relative to a followed course and/or a geographical position of the vehicle.

Abstract: The invention relates to a method for relaying an item of useful data by way of a transit station (SR), the item of useful data passing via the transit station from a first station (S1) to a second station (S2), wherein a station is a vehicle, a road infrastructure or a personal device of a pedestrian.

Abstract: A method for assisting the driving of a vehicle (V) on a road (R) having a portion (PV) with mandatory passing zones (ZP11-ZP22), wherein the vehicle (V) is capable to communicate by over-the-air waves and to be driven autonomously. The method comprises a step where, when the vehicle (V) reaches the vicinity of the portion of the road, the vehicle's relative position with respect to a predefined location of at least one mandatory passing zone (ZP21) is determined, then a path to follow passing through a mandatory passing zone (ZP21) is determined as a function of mapping information defining the mandatory passing zones, traffic information in the mandatory passing zones and the determined relative position of the vehicle, and then the driving of the vehicle (V) is controlled so that it takes this path to follow.
