Abstract

Method for calculating an interval within which is located a reference part (3) of a travelling railway vehicle (1), comprising:- calculating, at predefined and successive instants of time, by means on an electronic control unit (210):- a maximum and a minimum positions reached by the railway vehicle calculated both as points on a digital map (205) and based on signals provided by a receiver (220) which are indicative of the current absolute position of the railway vehicle;- a maximum and a minimum distances travelled by the railway vehicle with respect to a reference point, said distances calculated based on signals provided by an onboard odometry system (230);- at a selected instant of time (Tn) adding:- to the maximum and minimum positions calculated at an instant of time (T1) earlier than the selected instant of time (Tn), respectively, the difference between the value of the maximum distance calculated at the selected instant of time and the value of the maximum distance calculated at the earlier instant of time, thereby determining on the digital map a first reference maximum position, and the difference between the value of the minimum distance calculated at said selected instant of time and the value of the minimum distance calculated at said earlier instant of time, thereby determining on the digital map a second reference minimum position.The interval is assigned, as its advanced end, the most forward position between the position calculated for the first reference maximum position and the value of the maximum position calculated at the selected instant of time, and as its rear end, the most rearward position between the position calculated for the second reference minimum position and the value of the first minimum position calculated at the selected instant of time.
