A vehicle driving assistance system for helping keep or change the travel lane and the associated operating method are described. The system comprises devices (10a,10b) for detecting the environment surrounding the vehicle, which are adapted to provide signals indicating the position of the vehicle with respect to the configuration of the road travelled along, and signals indicating the presence of approaching vehicles. A processing and control unit (20) is arranged for:
- assessing the current driving condition on the basis of the vehicle position signals; and subsequently
- operating on-board signalling devices (40) so as to assume a first activated state indicating an incorrect driving manoeuvre, when a manoeuvre involving a change in the travel lane is in progress and the directional indicator devices have not been activated; or alternatively
- assessing the current driving condition on the basis of the vehicle presence signals, and subsequently
if a manoeuvre involving a change in the travel lane is in progress, operating the on-board signalling means (40) so as to assume a first activated state indicating an incorrect driving manoeuvre, when the directional indicator devices are activated and other vehicles are approaching; or
if the travel lane is maintained, operating the on-board signalling devices (40) so as to assume a second activated state providing a danger warning, when other vehicles are approaching.
