Abstract (en)

The present invention concerns a system (1) and a method for determining the speed of a guided vehicle (2) and/or the distance travelled by said guided vehicle (2), the latter being guided along a route by at least one rail (3), the system (1) comprising: - a laser beam emitter (11) configured for emitting a pulsed laser beam (111) aligned with a first direction (D1) configured for pointing to a first location on a rail surface (31); - at least one IR detector (12, 13) configured for having a field of view (F21, F22) aligned with a second direction (D21, D22) in order to point to a second location on the rail surface (31) when the system (1) is installed onboard the guided vehicle (2) and the latter is guided by said rail (3) along said route, wherein the second location is separated from the first location by a predefined distance ”X; - a processing unit (14) configured for determining the distance travelled by the guided vehicle (2) and/or its speed from the predefined distance ”X, a signal D (SD1, SD2) related to a detection by the IR detector (12, 13 respectively) of a warm spot at interaction area (I1, 12, 13) of the laser beam pulse with the rail surface (31) and control parameters related to the pulses emitted by the laser beam emitter (11).
