  • Patent number: 7412312
    Abstract: A system for automatically determining a public transport vehicle emergency braking characteristics, in particular of a railway vehicle, includes elements (1) for measuring the vehicle speed, elements (2) for measuring the distance travelled by it, and elements (3) for triggering an emergency braking of the vehicle to actuate its braking elements (4). The system includes elements for detecting (5) the activation of the elements (3) triggering the emergency braking and elements for detecting (5) when the vehicle stops, adapted to activate/deactivate the operation of elements (9) acquiring data concerning the speed and the distance travelled by the vehicle for a time interval running between the activation of the emergency triggering elements and the moment the vehicle stops, and elements (9) for analyzing the data to deliver at least a information concerning the distance travelled by the vehicle during the time interval.
