Abstract (en)
[origin: EP0435055A1] The device permits identification and determination of the instant when a plurality of vehicles (4) pass a reference line (30). <??>It comprises a mobile station (1) installed on the vehicle and a fixed station (2) arranged at the edge of a race track (3). The fixed station (2) transmits a synchronisation signal at low frequency of period T, which is received by a mobile station (1) which in its turn transmits a series of signals of duration Tn situated at a predetermined rank with respect to the time, to, marking each period T start. Conjointly, the mobile station (1) allots, to each signal Tn an identification code which is unique to a defined mobile object. The signals received by the fixed station (2) are stored in a memory storing, for each signal, its absolute time, its assignment to a given vehicle (4) and its amplitude. <??>The device is used for motor vehicle races comprising a large number of contestants. <IMAGE>
