Abstract
The invention concerns a driving aid system for supplying data to a vehicle running on an infrastructure, and comprising a magnetic marking formed on the infrastructure and adapted to encode data addressed to the vehicle, the data being modifiable, and a detection device comprising a plurality of magnetic sensors onboard the vehicle for detecting a total magnetic field including the magnetic field generated by the magnetic marking and for producing signals representing the total magnetic field, and a processing unit adapted to process the representative signals, and to determine a first distance between the vehicle and the magnetic marking, and to decode the data encoded on the magnetic marking.
